General

The Partnership is a publicly held limited partnership formed under the California Uniform Limited Partnership Act in December 1977. The Partnership raised $20,000,000 in gross proceeds by selling 40,000 units of limited partnership interest ("Units") in an interstate offering, which commenced in May 1978 and completed in November 1978. The Partnership was formed to engage in the business of developing and operating self-storage facilities for personal and business use.

The Partnership has reported annually to the SEC on Form 10-K which includes financial statements certified by its independent registered public accounting firm. The Partnership has also reported quarterly to the SEC on Form 10-Q, which includes unaudited financial statements with such filings. The Partnership expects to continue such reporting. Upon written request, the Partnership will mail a copy of its Annual Report on Form 10-K to the limited partners.

The public may read and copy any materials this Partnership files with the SEC at the SEC’s Public Reference Room at 450 Fifth Street, N.W., Washington, D.C. 20549. The public may obtain information on the operation of the Public Reference Room by calling the SEC at 1-800-732-0330. The Partnership does not maintain a website. However, the SEC maintains an Internet site that contains reports, proxy and information statements, and other information regarding issuers, including the Partnership, that file electronically with the SEC at http://www.sec.gov.

In 1995, there were a series of mergers among Public Storage Management, Inc. (which was the Partnership’s self-storage facilities operator), Public Storage, Inc. (which was one of the Partnership’s general partners) and their affiliates (collectively, “PSMI”), culminating in the November 16, 1995 merger (the “PSMI Merger”) of PSMI into Storage Equities, Inc., a real estate investment trust (“REIT”) organized as a California corporation. In the PSMI Merger, Storage Equities, Inc. was renamed Public Storage, Inc. and acquired substantially all of PSMI’s United States (“U.S.”) real estate operations and became a co-general partner of the Partnership and the operator of the Partnership’s self-storage facilities. Effective June 1, 2007, Public Storage, Inc. was reorganized into Public Storage (“PS”), a Maryland real estate investment trust.

The Partnership's general partners are PS and B. Wayne Hughes ("Hughes") (collectively referred to as the "General Partners"). Hughes has been a general partner of the Partnership since its inception. Hughes is chairman of the board of PS, and was its chief executive officer through November 7, 2002. Hughes and members of his family (the “Hughes Family”) own approximately 17.3% of the outstanding common shares of PS at March 16, 2010. PS, Hughes, and affiliates also own limited partnership interests, see Item 12 “Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters.”

The Partnership is managed, and its investment decisions are made by Hughes and the executive officers and trustees of PS. The limited partners of the Partnership have no right to participate in the operation or conduct of the Partnership’s business and affairs.

The term of the Partnership is until all properties have been sold and, in any event, not later than December 31, 2038.

The Impact of Current Economic Factors

The recessionary trends experienced in 2008 and 2009, including the contraction in economic activity and elevation in unemployment rates experienced in California, Florida and the U.S. have had a negative impact upon the Partnership’s business.

Operationally, the Partnership’s occupancies and rental rates have come under pressure as demand for self-storage space has softened. The Partnership, through its management agreement with PS (the “Management Agreement”), has responded by reducing rental rates, increasing promotional discounts, and increasing its marketing activities to stimulate additional demand for our storage space.

Investment Objectives and Policies

The Partnership’s investment objectives are to (i) preserve and protect invested capital, (ii) maximize the potential for appreciation in value of its investments, and (iii) provide for cash distributions from operations.

Following are the Partnership’s investment practices and policies. The Partnership does not anticipate any new investments, other than maintenance capital expenditures, and does not anticipate liquidating the real estate investments it now holds. While a vote of the limited partners is generally required to change the Partnership’s investment policies, the general partners hold a majority of the limited partnership units, and as a result, the General Partners could change these policies through their vote.

●	Our investments consist of 17 self-storage facilities located in the U.S. See “Self-Storage Facilities” below and Item 2 “Properties” for further information. These investments were acquired both for income and capital gains.

●	There is no limitation on the amount or percentage of assets, which can be invested in any specific person.

The Partnership does not anticipate issuing senior securities, making loans to other persons, investing in the securities of other issuers for the purpose of exercising control, underwriting the securities of other issuers, engaging in the purchase and sale of investments, offering securities in exchange for property, or repurchasing or otherwise reacquiring its outstanding securities. The Partnership may consider borrowing money with the intent of using the proceeds for distribution to partners. There can be no assurance that the Partnership would be able to access any such borrowings at rates of interest the Partnership found attractive in order to do so, if such a course of action were otherwise deemed necessary.

Self-Storage Facilities

Self-storage facilities are designed to offer accessible storage space for personal and business use at a relatively low cost. A user rents a fully enclosed space, securing the space with their own lock, which is for the user's exclusive use and to which only the user has access on an unrestricted basis during business hours. On-site operation is the responsibility of property managers who are supervised by district managers. Some self-storage facilities also include rentable uncovered parking areas for vehicle storage. Storage facility spaces are rented on a month-to-month basis. Rental rates vary according to the location of the property, the size of the storage space and other characteristics that affect the relative attractiveness of each particular space, such as whether the space has drive-up access or its proximity to elevators.

Users of space in self-storage facilities include individuals from virtually all demographic groups, as well as businesses. Individuals usually obtain this space for storage of furniture, household appliances, personal belongings, motor vehicles, boats, campers, motorcycles and other household goods. Businesses normally employ this space for storage of excess inventory, business records, seasonal goods, equipment and fixtures.

Self-storage facilities in which the Partnership has invested generally consist of three to seven buildings containing an aggregate of between approximately 265 to 1,700 storage spaces, most of which have between 25 and 400 square feet and an interior height of approximately 8 to 12 feet.

The Partnership's self-storage facilities are located in California and Florida and are generally located in heavily populated areas and close to concentrations of apartment complexes, single family residences and commercial developments. However, there may be circumstances in which it may be appropriate to own a property in a less populated area, for example, in an area that is highly visible from a major thoroughfare and close to, although not in, a heavily populated area. Moreover, in certain population centers, land costs and zoning restrictions may create a demand for space in nearby less populated areas.

As with most other types of real estate, the conversion of self-storage facilities to alternative uses in connection with a sale or otherwise would generally require substantial investment. However, the Partnership does not intend to convert its self-storage facilities to other uses.

Operating Strategies

The Partnership’s self-storage facilities are operated by PS under the “Public Storage” brand name, which the Partnership believes is the most recognized name in the self-storage industry. The major elements of the Partnership’s operating strategies are as follows:

Capitalize on recognition of the “Public Storage” name. PS has more than 30 years of operating experience in the self-storage business. PS has informed the Partnership that it is the largest self-storage facility operator in the U.S. in terms of both number of facilities and rentable space operated. PS believes that its marketing and advertising programs improve its competitive position in the market. The PS in-house yellow pages staff designs and places advertisements in directories in virtually all markets in which it operates. Customers calling either the PS toll-free telephone referral system, (800) 44-STORE, or a self-storage facility are directed to the PS national telephone reservation system where a trained representative discusses with the customer space requirements, price and location preferences and also informs the customer of other products and services provided by PS and its subsidiaries. The national telephone reservation system supports rental activity at all of the U.S. facilities operated by PS. PS also provides customers the opportunity to review space availability and make reservations online through the PS website, www.publicstorage.com.

Maintain high occupancy levels and increase annual realized rents. Subject to market conditions, the Partnership generally seeks to maximize revenues through the appropriate balance between occupancy, rental rates, and promotional discounting. Average occupancy for the Partnership’s self-storage facilities (excluding the Azusa property) was 89.8% in 2009 and 89.7% in 2008. Annual realized rents per occupied square foot decreased from $15.75 in 2008 to $15.23 in 2009. These amounts exclude the property operated pursuant to the management and performance agreement (the “Performance Agreement”) with a subsidiary of PS (the “PS Sub”). See Item 13 below and Note 5 to the Partnership’s December 31, 2009 financial statements for additional information on the Performance Agreement.

Systems and controls. PS has an organizational structure and a property operation system which links its corporate office with each of its self-storage facilities. This enables PS to obtain daily information from each facility and to achieve efficiencies in operations and maintain control over its space inventory, rental rates, promotional discounts and delinquencies, and to identify changing market conditions and operating trends as well as analyze customer data, and quickly change properties’ pricing and promotional mix on an automated basis. Expense management is achieved through centralized payroll and accounts payable systems and a comprehensive property tax appeals department. PS also has an extensive internal audit program designed to ensure adherence to specified policies and procedures, and thereby ensure proper handling of cash collections.

Professional property operations. There are approximately 4,900 persons who render services for the Public Storage system in the U.S., primarily personnel engaged in property operations, substantially all of whom are employed by a clearing company that provides certain administrative and cost-sharing services to PS and other owners of properties operated by PS.

Property Operator

The Partnership’s self-storage facilities are managed by PS pursuant to the Management Agreement.

Under the supervision of the Partnership, PS coordinates the operation of the facilities, establishes rental policies and rates, directs marketing activity and directs the purchase of equipment and supplies, maintenance activity and the selection and engagement of all vendors, suppliers and independent contractors.

PS engages, at the expense of the Partnership, employees for the operation of the Partnership's facilities, including property managers, assistant managers, relief managers, and billing and maintenance personnel. Some or all of these employees may be employed on a part-time basis and may also be employed by other persons, partnerships, real estate investment trusts or other entities owning facilities operated by PS.

In the purchasing of services such as advertising (including broadcast media advertising) and insurance, PS attempts to achieve economies-of-scale by combining the resources of the various facilities that it operates. Facilities operated by PS have historically carried comprehensive insurance, including fire, earthquake, liability and extended coverage.

PS has systems for managing space inventories, accounting and handling delinquent accounts, including a computerized network linking PS operated facilities. Property managers are trained in detailed operating procedures.

The Partnership's facilities are typically advertised via signage, yellow pages, flyers, broadcast media advertising (i.e. television and radio) in geographic areas in which many of the Partnership's facilities are located, as well as on the Internet. Broadcast media and other advertising costs are charged to the Partnership's facilities located in geographic areas affected by the advertising.

Under the supervision of the Partnership, PS seeks to increase the cash flow generated by the Partnership’s facilities by: a) regularly evaluating call volume, reservation activity, and move-in/move-out rates for each property relative to marketing activities, b) evaluating market supply and demand factors, and based upon these analyses, adjusting the marketing activities and rental rates, c) attempting to maximize revenues through evaluating the appropriate balance between occupancy, rental rates, and promotional discounting, and d) controlling expense levels.

Under the Management Agreement, the Partnership pays PS a flat fee of 6% of the gross revenues of the self-storage facilities operated for the Partnership. For as long as the Management Agreement between the Partnership and PS is in effect, PS has granted the Partnership a non-exclusive license to use two PS service marks and related designs including the "Public Storage" name in conjunction with rental and operation of facilities managed pursuant to the Management Agreement. Upon termination of the Management Agreement, the Partnership would no longer have the right to use the service marks and related designs. The General Partners believe that the loss of the right to use the service marks and related designs could have a material adverse effect on the Partnership’s business.

The Management Agreement between the Partnership and PS provides that the Management Agreement may be terminated without cause upon 60 days written notice by the Partnership or six months notice by PS.

Competition

Self-storage facilities generally draw customers from residents within a three to five mile radius. Many of the Partnership’s facilities operate within three to five miles of well-located and well-managed competitors (including those facilities owned by PS) that seek the same group of customers through many of the same marketing channels that PS uses in managing our facilities, including yellow page advertising, Internet advertising, as well as signage and banners. As a result, competition is significant and affects the occupancy levels, rental rates, rental income and operating expenses of our facilities. Any increase in availability of funds for investment in real estate may accelerate competition. The Partnership believes that the significant operating and financial experience of PS, and the “Public Storage” brand name recognition should enable the Partnership to continue to compete effectively with other entities.

Other Business Activities

PS owns a corporation that reinsures policies issued to the Partnership’s tenants against lost or damaged goods stored by tenants in the Partnership’s self storage facilities. We believe that the availability of insurance reduces our potential liability to tenants for losses to their goods from theft or destruction. This corporation receives the premiums and bears the risks associated with the reinsurance. The Partnership receives a fee (an “Access Fee”) from this corporation in return for providing tenant listings. This Access Fee is based on the number of spaces the Partnership has to rent.

A subsidiary of PS sells locks and boxes to the general public and tenants associated with securing their spaces and storing and moving their goods. The subsidiary of PS receives the revenues and bears the cost of the activities. We believe these activities, along with availability of insurance as noted above, supplement and strengthen the Partnership’s existing self-storage business by further meeting the needs of storage customers.

Federal Income Tax

Public Storage Properties IV, Ltd. is treated as a partnership for federal and state income tax purposes with the taxable income of the entity allocated to each partner in accordance with the partnership agreement. Accordingly, no federal income tax expense is recorded by the Partnership.

Employees

The Partnership has no direct employees. There are approximately 54 persons who render services on behalf of the Partnership. These persons include resident managers, assistant managers, relief managers, area managers, and administrative and maintenance personnel. Some employees may be employed on a part-time basis and may be employed by other persons, partnerships or other entities owning facilities operated by PS.

Seasonality

The Partnership experiences minor seasonal fluctuations in the occupancy levels of its self-storage facilities with occupancies higher in the summer months than in the winter months. The Partnership believes that these fluctuations result in part from increased moving activity during the summer months.

ITEM 1A. Risk Factors

In addition to the other information in our Annual Report on Form 10-K, you should consider the risks described below that we believe may be material to investors in evaluating the Partnership. This section contains forward-looking statements, and in considering these statements, you should refer to the qualifications and limitations on our forward-looking statements that are described in Forward Looking Statements at the beginning of Item 1.

The General Partners control the Partnership as a group.

Public Storage is a general partner and beneficially owns approximately 29.2% of our outstanding limited partnership units. In addition, B. Wayne Hughes, General Partner of the Partnership, and Chairman of PS and members of his family beneficially own 33.0% of the limited partnership units. As a result, the General Partners, as a group, control matters submitted to a vote of our unitholders, including amending our organizational documents, dissolving the Partnership and approving other such transactions.

Since our business consists primarily of operating real estate, we are subject to the risks related to the ownership and operation of real estate that can adversely impact our business and financial condition.

The value of our investments may be reduced by general risks of real estate ownership. Since we derive substantially all of our income from real estate operations, we are subject to the general risks of acquiring and owning real estate-related assets, including:

·	lack of demand for rental spaces or units in a locale;

·	changes in general economic or local conditions;

·	natural disasters, such as earthquakes and floods; which could exceed the aggregate limits of our insurance coverage;

·	potential terrorist attacks;

·	changes in supply of or demand for similar or competing facilities in an area;

·	the impact of environmental protection laws;

·	changes in interest rates and availability of permanent mortgage funds which may render the sale or financing of a nonstrategic property difficult or unattractive including the impact of the current turmoil in the credit markets;

·	increases in insurance premiums, property tax assessments and other operating and maintenance expenses;

·	adverse changes in tax, real estate and zoning laws and regulations; and

·	tenant and employment-related claims.

In addition, we self-insure certain of our property loss, liability, and workers compensation risks for which other real estate companies may use third-party insurers. This results in a higher risk of losses that are not covered by third-party insurance contracts.

There is significant competition among self-storage facilities and from other storage alternatives. All of our properties are self-storage facilities, which generated substantially all of our revenue for the year ended December 31, 2009. Local market conditions will play a significant part in how competition will affect us. Competition in the market areas in which many of our properties are located from other self-storage facilities and other storage alternatives is significant and has affected the occupancy levels, rental rates and operating expenses of some of our properties. Any increase in availability of funds for investment in real estate may accelerate competition. Further development of self-storage facilities may intensify competition among operators of self-storage facilities in the market areas in which we operate.

We may incur significant environmental costs and liabilities. As an owner and operator of real properties, under various federal, state and local environmental laws, we are required to clean up spills or other releases of hazardous or toxic substances on or from our properties. Certain environmental laws impose liability whether or not the owner knew of, or was responsible for, the presence of the hazardous or toxic substances. In some cases, liability may not be limited to the value of the property. The presence of these substances, or the failure to properly remediate any resulting contamination, whether from environmental or microbial issues, also may adversely affect the owner’s or operator’s ability to sell, lease or operate its property or to borrow using its property as collateral.

We have conducted preliminary environmental assessments on the Partnership’s properties to evaluate the environmental condition of, and potential environmental liabilities associated with, our properties. These assessments generally consist of an investigation of environmental conditions at the property (not including soil or groundwater sampling or analysis), as well as a review of available information regarding the site and publicly available data regarding conditions at other sites in the vicinity. In connection with these property assessments, we have become aware that prior operations or activities at some facilities or from nearby locations have or may have resulted in contamination to the soil or groundwater at these facilities. In this regard, some of our facilities are or may be the subject of federal or state environmental investigations or remedial actions. Although we cannot provide any assurance, based on the preliminary environmental assessments, we believe we have funds available to cover any liability from environmental contamination or potential contamination and we are not aware of any environmental contamination of our facilities material to our overall business, financial condition or results of operations.

There has been an increasing number of claims and litigation against owners and managers of rental properties relating to moisture infiltration, which can result in mold or other property damage. When we receive a complaint concerning moisture infiltration, condensation or mold problems and/or become aware that an air quality concern exists, we implement corrective measures in accordance with guidelines and protocols we have developed with the assistance of outside experts. We seek to work proactively with our tenants to resolve moisture infiltration and mold-related issues, subject to our contractual limitations on liability for such claims. However, we can give no assurance that material legal claims relating to moisture infiltration and the presence of, or exposure to, mold will not arise in the future.

Property taxes can increase and cause a decline in yields on investments. Each of our properties is subject to real property taxes. These property taxes may increase in the future as property tax rates change and as our properties are assessed or reassessed by tax authorities. We believe that our 12 California properties in particular are assessed at levels that are significantly below current fair values, due to longstanding laws that generally limit assessment increases if there is no change in ownership or new construction. Recent shortfalls in tax revenues of local governments may cause pressure to increase tax rates, assessment levels, or eliminate the longstanding limits on assessment increases and limits on tax rates. In addition, changes in ownership, either direct or indirect (such as by transfers of partnership interests), could trigger a California reassessment. Any such increases could adversely impact our profitability.

We must comply with the Americans with Disabilities Act and fire and safety regulations, which can require significant expenditures. All our properties must comply with the Americans with Disabilities Act and with related regulations (the “ADA”). The ADA has separate compliance requirements for “public accommodations” and “commercial facilities,” but generally requires that buildings be made accessible to persons with disabilities. Various state laws impose similar requirements. A failure to comply with the ADA or similar state laws could result in government imposed fines on us and could award damages to individuals affected by the failure. In addition, we must operate our properties in compliance with numerous local fire and safety regulations, building codes, and other land use regulations. Compliance with these requirements can require us to spend substantial amounts of money, which would reduce cash otherwise available for distribution to shareholders. Failure to comply with these requirements could also affect the marketability of our real estate facilities.

We incur liability from tenant and employment-related claims. From time to time we must resolve tenant claims and employment-related claims by corporate level and field personnel.

Public Storage’s acquisitions or development of properties may subject the Partnership to additional risks.

Public Storage has historically been an acquirer and developer of real estate facilities, most recently acquiring 646 self-storage facilities located in the U.S. in 2006 with its acquisition of Shurgard Storage Centers. Such acquisitions or newly developed facilities do not change the financial interests of the Partnership. However, individual Partnership properties may experience a decrease in move-ins, reductions to rental rates, increases to promotional discounts, or other negative impacts to revenues in the short and/or long-term due to the competitive impact of Public Storage management of the newly acquired or developed facilities, particularly with respect to those facilities that are close to the Partnership’s facilities.

Global economic conditions could adversely affect our business, financial condition, growth and access to capital.

There continues to be global economic uncertainty, elevated levels of unemployment, reduced levels of economic activity, and it is uncertain as to when economic conditions will improve. These negative economic conditions in the markets where we operate facilities, and other events or factors that adversely affect disposable income of the consumer, have and are likely to continue to adversely affect our business.

As a further result of the current global financial crisis, our ability to borrow at reasonable rates may be adversely affected by challenging credit markets conditions. While we currently believe that we have sufficient working capital and cash flow from operations to continue to operate our business as usual, long-term continued turbulence in the credit markets and in the national economy may adversely affect our access to capital.

We have become increasingly dependent upon automated processes, telecommunications, and the Internet and are faced with system security risks.

We have become increasingly centralized and dependent upon automated information technology processes, and certain critical components of our operating systems are dependent upon third party providers. As a result, we could be severely impacted by a catastrophic occurrence, such as a natural disaster or a terrorist attack, or a circumstance that disrupted operations at our third party providers. Even though we believe we utilize appropriate duplication and back-up procedures, a significant outage in our third party providers could negatively impact our operations. In addition, a portion of our business operations are conducted over the Internet, increasing the risk of viruses that could cause system failures and disruptions of operations. Experienced computer programmers may be able to penetrate our network security and misappropriate our confidential information, create system disruptions or cause shutdowns. Nearly half of our move-ins comes from sales channels dependent upon telecommunications (telephone or Internet).

We are subject to laws and governmental regulations and actions that affect our operating results and financial condition.

Our business is subject to regulation under a wide variety of U.S. federal, state and local laws, regulations and policies including those imposed by the SEC and the Sarbanes-Oxley Act of 2002, as well as applicable labor laws. Although we have policies and procedures designed to comply with applicable laws and regulations, failure to comply with the various laws and regulations may result in civil and criminal liability, fines and penalties, increased costs of compliance and restatement of our financial statements.

There can also be no assurance that, in response to current economic conditions or the current political environment or otherwise, laws and regulations will not be implemented or changed in ways that adversely affect our operating results and financial condition, such as current federal legislative proposals to expand health care coverage costs or facilitate union activity or otherwise increase operating costs.

Terrorist attacks and the possibility of wider armed conflict may have an adverse impact on our business and operating results and could decrease the value of our assets.

Terrorist attacks and other acts of violence or war could have a material adverse impact on our business and operating results. There can be no assurance that there will not be further terrorist attacks against the U.S. Attacks or armed conflicts that directly impact one or more of our properties could significantly affect our ability to operate those properties and thereby impair our operating results. Further, we may not have insurance coverage for losses caused by a terrorist attack. Such insurance may not be available, or if it is available and we decide to obtain such terrorist coverage, the cost for the insurance may be significant in relationship to the risk overall. In addition, the adverse effects that such violent acts and threats of future attacks could have on the U.S. economy could similarly have a material adverse effect on our business and results of operations. Finally, further terrorist acts could cause the U.S. to enter into a wider armed conflict, which could further impact our business and operating results.

The Partnership’s cash flows could decline with respect to the Azusa Property when the Performance Agreement expires.

Pursuant to the Performance Agreement described further in Item 13, the Partnership is guaranteed an annual increase in operating income of at least 1% each year with respect to the Azusa Property, and accordingly, recorded net operating income of $1,392,000 from this property during the year ended December 31, 2009. The Performance Agreement will expire on December 31, 2015, at which time the Partnership will earn the underlying net cash flow of the Azusa Property, which totaled $1,378,000 for the year ended December 31, 2009. If the amount payable under the Performance Agreement in 2015 exceeds the Azusa property’s underlying cash flow beginning in 2016, the Partnership’s cash flow from operations will be adversely impacted.

Increases in interest rates may adversely affect the price of our partnership units.

One of the factors that influence the market price of our partnership units is the annual rate of distributions that we pay on the securities, as compared with interest rates. An increase in interest rates may lead purchasers of partnership units to demand higher annual distribution rates, which could adversely affect the market price of our partnership units.

Our ownership interest in STOR-Re may lose value or become a liability.

The Partnership has a 1.8% ownership interest in STOR-Re Mutual Insurance Corporation (“STOR-Re”), which was formed in 1994 as an association captive insurance company, and is controlled by PS. STOR-Re provided limited property and liability insurance coverage to the Partnership, PS, and affiliates of PS for losses occurring prior to April 1, 2004. Liabilities for losses and loss adjustment expenses include an amount determined from loss reports and individual cases and an amount, based on recommendations from an outside actuary that is a member of the American Academy of Actuaries, using a frequency and severity method, for losses incurred but not reported. Determining the liability for unpaid losses and loss adjustment expense is based upon estimates and while we believe that the amount is adequate, the ultimate loss may be in excess of or less than the amounts provided, which may result in a reduction in the value of the Partnership’s investment or could result in future payments to STOR-Re if its reserves were determined to be inadequate. Financial data with respect to STOR-Re is included in Note 5 to the Partnership’s December 31, 2009 financial statements.

Developments in California may have an adverse impact on our business and financial results.

The state of California and many local jurisdictions are facing severe budgetary problems and deficits. Action that may be taken in response to these problems, such as increases in property taxes on commercial properties, changes to sales taxes, adoption of a proposed “Business Net Receipts Tax” or other governmental efforts to raise revenues could adversely impact our business and results of operations. In addition, we could be adversely impacted by efforts to reenact legislation mandating medical insurance for employees of California businesses and members of their families.

(a)

This property is operated by a subsidiary of PS (the “PS Sub”) pursuant to a Performance Agreement which will expire on December 31, 2015. See Note 5 to the Partnership’s December 31, 2009 financial statements for further information regarding the terms of the Performance Agreement. Prior to the initiation of the Performance Agreement, this facility had 105,000 net rentable square feet of storage space, and has been increased to 173,000 net rentable square feet by the PS Sub.

For the year ended December 31, 2009, the weighted average occupancy level and the average realized rent per occupied square foot for our self-storage facilities (excluding the Azusa property) were approximately 89.8% and $15.23, respectively.

The Partnership does not have any agreements to buy or sell any real estate. The Partnership does not anticipate any new investments, other than maintenance capital expenditures, and does not anticipate liquidating the real estate investments it now holds.

As of December 31, 2009, none of the properties were encumbered by mortgage debt.

ITEM 3. Legal Proceedings

Brinkley v. Public Storage, Inc. (filed April 2005) (Superior Court of California – Los Angeles County)

The plaintiff sued PS on behalf of a purported class of California non-exempt employees based on various California wage and hour laws. Plaintiff sought certification for alleged meal period violations, rest period violations, failure to pay for travel time, failure to pay for mileage reimbursement, and for wage statement violations. The Court certified subclasses based only on alleged meal period and wage statement violations. In June 2007, the Court granted PS’ summary judgment motion as to the causes of action relating to the subclasses certified and dismissed those claims. Plaintiff appealed. The Court of Appeals sustained the dismissal. The California Supreme Court granted review but deferred the matter pending disposition of a related issue in another case.

Other Items

PS and the Partnership are a party to various claims, complaints, and other legal actions that have arisen in the normal course of business from time to time, that are not described above. We believe that it is unlikely that the outcome of these other pending legal proceedings including employment and tenant claims, in the aggregate, will have a material adverse effect upon the Partnership’s operations or financial position.

PART II

ITEM 5.

Market for the Registrant's Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

The Partnership has no common stock.

The Units are not listed on any national securities exchange or quoted on the NASDAQ System and there is no established public trading market for the Units. Secondary sales activity for the Units has been limited and sporadic. The General Partners monitor transfers of the Units (a) because the admission of the transferee as a substitute limited partner requires the consent of the General Partners under the Partnership's Amended and Restated Certificate and Agreement of Limited Partnership, (b) in order to ensure compliance with safe harbor provisions to avoid treatment as a "publicly-traded partnership" for tax purposes, and (c) because the General Partners (and their affiliates) have purchased Units. However, the General Partners do not have first hand information regarding the prices at which secondary sale transactions in the Units have been effectuated. Various organizations offer to purchase and sell limited partnership interests (including securities of the type such as the Units) in secondary sales transactions. Various publications such as The Stanger Report summarize and report information (on a monthly, bimonthly or less frequent basis) regarding secondary sales transactions in limited partnership interests (including the Units), including the prices at which such secondary sales transactions are effectuated.

Exclusive of the General Partners' interest in the Partnership, as of December 31, 2009, there were approximately 928 unitholders of record.

Distributions to the general and limited partners of all cash available for distribution (as defined) are made quarterly. Cash available for distribution is generally net cash provided by operating activities, less deductions to pay, establish or revise reserves for all other expenses (other than incentive distributions to the general partner) and capital improvements, plus net proceeds from any sale or financing of the Partnership's properties.

Reference is made to Items 6 and 7 hereof for information on the amount of such distributions.

ITEM 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis should be read in conjunction with the Partnership’s financial statements and notes thereto.

Forward Looking Statements

Factors and risks that may impact our future results and performance include, but are not limited to, those described in Item 1A, "Risk Factors" and in our other filings with the Securities and Exchange Commission (“SEC”).

Critical Accounting Policies

Management’s Discussion and Analysis of Financial Condition and Results of Operations discusses our financial statements, which have been prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”). The preparation of our financial statements and related disclosures in conformity with GAAP and our discussion and analysis of our financial condition and results of operations requires management to make judgments, assumptions and estimates that affect the amounts reported in our financial statements and accompanying notes. The notes to the Partnership’s December 31, 2009 financial statements, primarily Note 2, summarize the significant accounting policies and methods used in the preparation of our financial statements and related disclosures.

Management believes the following are critical accounting policies, the application of which has a material impact on the Partnership’s financial presentation. That is, they are both important to the portrayal of our financial condition and results, and they require management to make judgments and estimates about matters that are inherently uncertain.

Impairment of Real Estate: Substantially all of our assets consist of real estate. On a quarterly basis, we evaluate our real estate for impairment. The evaluation of real estate for impairment includes determining whether indicators of impairment exist, which is a subjective process. When any indicators of impairment are found, the evaluation then entails projections of future operating cash flows, which also involves significant judgment. We identified no such impairments at December 31, 2009. However, future events, or facts and circumstances that currently exist, that we have not yet identified, could cause us to conclude in the future that our real estate is impaired. Any resulting impairment loss could have a material adverse impact on the Partnership’s financial condition and results of operations.

Estimated Useful Lives of Long-Lived Assets: Substantially all of our assets consist of depreciable, long-lived assets. We record depreciation expense with respect to these assets based upon their estimated useful lives. Any change in the estimated useful lives of those assets, caused by functional or economic obsolescence or other factors, could have a material adverse impact on our financial condition or results of operations.

Accruals for Contingencies: We are exposed to business and legal liability risks with respect to events that have occurred, but in accordance with GAAP, we have not accrued for certain potential liabilities because the loss is either not probable or not estimable or because we are not aware of the event. Future events and the results of pending litigation could result in such potential losses becoming probable and estimable, which could have a material, adverse impact on our financial condition or results of operations. Significant unaccrued losses that we have determined are at least reasonably possible are described in Notes 5 and 8 to the Partnership’s December 31, 2009 financial statements.

Accruals for Operating Expenses: We accrue for property tax expense and other operating expenses based upon estimates and historical trends and current and anticipated local and state government rules and regulations. If these estimates and assumptions are incorrect, our expenses could be misstated.

Overview of Management’s Discussion and Analysis of Operations

The self-storage industry is highly fragmented and is composed predominantly of numerous local and regional operators. Competition in the markets in which we operate is significant and has increased over the past several years due to additional development of self-storage facilities. We believe that the increase in competition has had a negative impact on the Partnership’s occupancy levels and rental rates in many markets. However, we believe that the Partnership’s affiliation with Public Storage (“PS”) provides several distinguishing characteristics that enable the Partnership to compete effectively with other owners and operators.

PS is the largest owner and operator of self-storage facilities in the U.S. All of the PS facilities in the U.S. are operated under the “Public Storage” brand name, which we believe is the most recognized and established name in the self-storage industry. The concentration of most of the PS and Partnership properties in major metropolitan centers makes various promotional and media programs, such as television, yellow pages, and Internet keyword bidding, far more economical for us than for our competitors.

The self-storage industry is subject to general economic conditions, particularly those that affect the disposable income and spending of consumers, as well as those that affect moving trends. Due to the recessionary pressures in the U.S., demand for self-storage space was soft in 2009 and continues to be soft. As a result, we are experiencing downward pressure on occupancy levels, rental rates, and revenues in our self-storage facilities.

We will continue to focus our growth strategies on improving the operating performance of our existing self-storage properties primarily through increases in revenues achieved through the national telephone reservation system and associated marketing efforts. We expect any potential future increases in rental income to come primarily from increases in realized rent rather than increases in occupancy, although there can be no assurance that we will experience such increases.

Results of Operations

Year ended December 31, 2009 as compared to year ended December 31, 2008:

The Partnership's net income for 2009 was $9,033,000, as compared to $9,250,000 for 2008, representing a decrease of $217,000 or 2.3%. Property net operating income (rental income less cost of operations, management fees paid to an affiliate and depreciation expense) decreased $193,000 or 2.6% from $7,557,000 in 2008 to $7,364,000 in 2009.

Rental income for 2009 was $11,166,000, as compared to $11,501,000 for 2008, representing a decrease of $335,000 or 2.9%. The decrease in rental income was primarily a result of a 3.3% decrease in realized rent per square foot. Annual realized rent for 2009 decreased to $15.23 per occupied square foot, as compared to $15.75 per occupied square foot for 2008. Weighted average occupancy levels at the self-storage facilities increases slightly to 89.8% in 2009 from 89.7% in 2008. These amounts exclude the property operated pursuant to the management and performance agreement (the “Performance Agreement”) with a subsidiary of PS (the “PS Sub”). See Note 5 to the Partnership’s December 31, 2009 financial statements for additional information.

We believe that demand for self-storage space has been negatively impacted by general economic conditions, the slowdown in housing sales and moving activity, as well as increased competition. Based upon certain comparative December 31, 2009 key operating metrics for the Partnership’s self-storage facilities including 6.7% lower in place annual rent per occupied square foot from $19.06 at December 31, 2008 to $17.79 at December 31, 2009 and a 1.6% increase in square foot occupancy from 87.9% at December 31, 2008 to 89.3% at December 31, 2009, we expect that the revenue will decline for the Partnership’s facilities for the three months ending March 31, 2010, as compared to the same period in 2009. In place annual rent per occupied square foot represents annualized contractual rents per occupied square foot without reductions for promotional discounts and excludes late charges and administrative fees. The Partnership’s operating strategy will be to continue to focus on maintaining occupancy levels by adjusting rental rates, promotional discounts and marketing activities. It is unclear to us how much the above mentioned factors will impact our revenues beyond the first quarter of 2010.

Other income was $386,000 for 2009, as compared to $471,000 for 2008, representing a decrease of $85,000 or 18.0%. Included in other income on our statements of income are access fees paid by PS Insurance Company - Hawaii, Ltd. (“PSICH”), a corporation owned by PS (described more fully in Note 5 to the Partnership’s December 31, 2009 financial statements), totaling $374,000 and $412,000 for 2009 and 2008, respectively. The decline is due to adjustments in timing of the recording of income in 2008 due to changes in accounting estimates. Interest income on cash balances for 2009 declined as compared to 2008 due to significant decreases in average interest rates. The Partnership has $654,000 in cash on hand at December 31, 2009 invested primarily in money-market funds, which earn nominal rates of interest in the current interest rate environment.

Revenues from Affiliates under the Performance Agreement increased $58,000 or 4.3% to $1,392,000 for 2009 from $1,334,000 for 2008. See Note 5 to the Partnership’s December 31, 2009 financial statements for further discussion of the nature of these revenues.

Cost of operations, including management fees paid to an affiliate, (see Note 5 to the Partnership’s December 31, 2009 financial statements) for 2009 was $3,369,000 compared to $3,522,000 for 2008, representing a decrease of $153,000 or 4.3%, as reductions in repairs and maintenance, payroll, advertising and promotion, property taxes and insurance expenses, were partially offset by increases in office expense and professional fees.

Depreciation expense was $433,000 and $422,000 for 2009 and 2008, respectively, representing an increase of $11,000 or 2.6%. The increase in depreciation expense is primarily related to additional capital improvements.

Administrative expense was $109,000 and $112,000 in 2009 and 2008, respectively, representing a decrease of $3,000 or 2.7%.

Year ended December 31, 2008 as compared to year ended December 31, 2007:

The Partnership's net income for 2008 was $9,250,000, as compared to $8,809,000 for 2007, representing an increase of $441,000 or 5.0%. Property net operating income (rental income less cost of operations, management fees paid to an affiliate and depreciation expense) increased $257,000 or 3.5% from $7,300,000 in 2007 to $7,557,000 in 2008.

Rental income for 2008 was $11,501,000 compared to $11,271,000 for 2007, representing an increase of $230,000 or 2.0%. The increase in rental income is attributable primarily to an increase in the weighted average occupancy levels at the self-storage facilities from 89.0% for 2007 to 89.7% for 2008, as well as an increase in annualized realized rent for 2008 to $15.75 per occupied square foot, as compared to $15.56 per occupied square foot for 2007. These amounts exclude the property operated pursuant to the Performance Agreement with the PS Sub. See Note 5 to the Partnership’s December 31, 2009 financial statements for additional information.

Other income was $471,000 for 2008, as compared to $340,000 for 2007, representing an increase of $131,000 or 38.5%. Included in other income for 2008 are additional access fees paid by PSICH totaling $65,000 for amounts earned in 2007. These additional access fees were paid in 2008 as a result of a change in PSICH’s accounting estimates which determine such fees. Included in other income on our statements of income are access fees totaling $412,000 (which includes the $65,000 for amounts earned in 2007) and $199,000 for 2008 and 2007, respectively.

Revenues from Affiliates under the Performance Agreement increased $60,000 or 4.7% to $1,334,000 for 2008 from $1,274,000 for 2007. See Note 5 to the Partnership’s December 31, 2009 financial statements for further discussion of the nature of these revenues.

Cost of operations, including management fees paid to an affiliate, (see Note 5 to the Partnership’s December 31, 2009 financial statements) for 2008 was $3,522,000 compared to $3,550,000 for 2007, representing a decrease of $28,000 or 0.8%, as reductions in advertising and promotion, repairs and maintenance and insurance expenses, were mostly offset by increases in payroll, management fees and property taxes expenses.

Depreciation expense was $422,000 and $421,000 for 2008 and 2007, respectively, representing an increase of $1,000.

Administrative expense was $112,000 and $105,000 in 2008 and 2007, respectively, representing an increase of $7,000 or 6.7%. This increase is attributable to increased allocated expenses and professional fees.

Liquidity and Capital Resources

At December 31, 2009, the Partnership had cash of $654,000 as compared to total liabilities of $834,000. Cash generated from operations ($9,747,000 for the year ended December 31, 2009) has been sufficient to meet all current obligations of the Partnership. Capital improvements totaled $427,000 in 2009, $419,000 in 2008 and $311,000 in 2007. Capital improvements are budgeted at $309,000 for 2010.

As of December 31, 2009, the Partnership had $331,000 in amounts due to affiliate. These amounts arose in December 2009 from the timing of the settlement of shared costs and were paid in January 2010.

Distributions

The Partnership Agreement requires that cash available for distribution (cash flow from all sources less cash necessary for any obligations or capital improvement needs) be distributed at least quarterly. During the year ended December 31, 2009, we paid distributions to the limited and general partners totaling $7,280,000 ($182.00 per unit) and $2,525,000, respectively. During the year ended December 31, 2008, we paid distributions to the limited and general partners totaling $6,680,000 ($167.00 per unit) and $2,317,000, respectively. During the year ended December 31, 2007, we paid distributions to the limited and general partners totaling $8,000,000 ($200.00 per unit) and $2,774,000, respectively. Future distribution rates will be adjusted to levels which are supported by operating cash flow after provisions for capital improvements and any other necessary obligations.

ITEM 7A. Quantitative and Qualitative Disclosures about Market Risk

ITEM 9A. Controls and Procedures

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

Public Storage maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in reports the Partnership files and submits under the Securities Exchange Act of 1934, as amended, (“Exchange Act”) is recorded, processed, summarized and reported within the time periods specified in accordance with SEC guidelines and that such information is communicated to the Partnership’s management, including Public Storage’s Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure based on the definition of "disclosure controls and procedures" in Rules 13a-15(e) and 15d-15(e) of the Exchange Act. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives and management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures in reaching that level of reasonable assurance.

As of December 31, 2009, Public Storage carried out an evaluation, under the supervision and with the participation of the Partnership’s management, including Public Storage’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Partnership’s disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act. Based on that evaluation, Public Storage’s Chief Executive Officer and Chief Financial Officer concluded that the Partnership’s disclosure controls and procedures were effective as of December 31, 2009, at a reasonable assurance level.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act. Under the supervision and with the participation of our management, including Public Storage’s Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control-Integrated Framework issued by the Committee on Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the framework in Internal Control-Integrated Framework, our management concluded that our internal control over financial reporting was effective as of December 31, 2009.

This annual report does not include an audit report of the Partnership’s independent registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to audit by the Partnership’s independent registered public accounting firm pursuant to temporary rules of the SEC that permit the Partnership to provide only management’s report in this annual report.

Changes in Internal Control over Financial Reporting

There have not been any changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the fourth quarter of 2009 to which this report relates that have materially affected, or are reasonable likely to materially affect, our internal control over financial reporting.

ITEM 11. Executive Compensation

The Partnership has no subsidiaries, directors or officers. See Item 13 for a description of certain transactions between the Partnership and its General Partners and their affiliates.

ITEM 12.

Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters

(a) At March 25, 2010, the following beneficially owned more than 5% of the Units:

Title of Class	Name and Address of Beneficial Owners	Beneficial Ownership	Percent of Class
Units of Limited Partnership Interest	Public Storage 701 Western Avenue Glendale, California 91201	11,671 Units (1)	29.2%

Units of Limited Partnership Interest	B. Wayne Hughes, PS Orangeco Partnerships, Inc. 701 Western Avenue Glendale, California 91201	13,191 Units (2)	33.0%

(1)	Includes (i) 11,365 Units owned by PS as to which PS has sole voting and dispositive power, and (ii) 306 Units which, on January 1, 2009, PS exercised its option to acquire from Tamara Hughes Gustavson, an adult daughter of Hughes.

(2)

Includes (i) 5,892 Units owned by BWH Marina Corporation II, a corporation wholly-owned by Hughes, as to which Hughes has sole voting and dispositive power and (ii) 7,299 Units owned by PS Orangeco Partnerships, Inc., a corporation in which Hughes and members of his family own approximately 48% of the voting stock, PS owns 46% and members of PS’s management and related individuals own approximately 6%.

(b) The Partnership has no officers and directors.

The General Partners (or their predecessor-in-interest) have contributed $202,020 to the capital of the Partnership and as a result participate in the distributions to the limited partners and in the Partnership's profits and losses in the same proportion that the General Partners' capital contribution bears to the total capital contribution (approximately $161,616 was contributed by PS and $40,404 was contributed by Mr. Hughes). In 1995, Mr. Hughes contributed his ownership and rights to distributions from the Partnership to BWH Marina Corporation II, a corporation wholly-owned by Mr. Hughes. As such, Mr. Hughes continues to act as a general partner but receives no direct compensation or other consideration from the Partnership. Information regarding ownership of Units by PS and Hughes, the General Partners, is set forth under section (a) above. Dann V. Angeloff, a trustee of PS, beneficially owns nine Units (0.02% of the Units). The trustees and executive officers of PS (including Hughes), as a group (16 persons), beneficially own an aggregate of 13,219 Units, representing 33.0% of the Units (including the 5,892 Units owned by Hughes and the 7,299 Units owned by PS Orangeco Partnerships, Inc.).

(c) The Partnership knows of no contractual arrangements, the operation of the terms of which may at a subsequent date result in a change in control of the Partnership, except for articles 16, 17 and 21.1 of the Partnership's Amended Certificate and Agreement of Limited Partnership (the "Partnership Agreement"), a copy of which is included in the Partnership's prospectus included in the Partnership's Registration Statement File No. 2-60530. Those articles provide, in substance, that the limited partners shall have the right, by majority vote, to remove a general partner and that a general partner may designate a successor with the consent of the other general partner and a majority of the limited partners.

ITEM 13. Certain Relationships, Related Transactions and Trustee Independence

The Partnership Agreement provides that the General Partners will be entitled to cash incentive distributions in an amount equal to (i) 8% of distributions of cash flow from operations until the distributions to all partners from all sources equal their capital contributions; thereafter, 25% of distributions of cash flow from operations, and (ii) 25% of distributions from net proceeds from sale and financing of the Partnership's properties remaining after distribution to all partners of any portion thereof required to cause distributions to partners from all sources to equal their capital contributions. During 1986, the partners received cumulative distributions equal to their capital contributions. Mr. Hughes has assigned his ownership and distribution rights in the Partnership to BWH Marina Corporation II (“BWH Marinas”). In addition to their distribution rights with respect to their general partner’s interests, PS and BWH Marinas own 11,365 and 5,892 Units, respectively. During 2009, PS and BWH Marinas received $2,020,000 and $505,000, respectively, in cash distributions related to their general partner’s ownership interests. As described above, the General Partners also hold Limited Partnership Units. Through these holdings, PS and the Hughes Family received $3,511,000 and $1,087,000, respectively, of cash distributions during 2009.

The Partnership has a management agreement (the “Management Agreement”) with PS (as successor-in-interest to PSMI). Under the Management Agreement, the Partnership pays PS a fee of 6% of the gross revenues of the mini-warehouse properties operated for the Partnership. For as long as the Management Agreement is in effect, PS has granted the Partnership a non-exclusive license to use two PS service marks and related designs, including the “Public Storage” name, in conjunction with rental and operation of facilities managed pursuant to the Management Agreement. Upon termination of the Management Agreement, the Partnership would no longer have the right to use the service marks and related designs. The General Partners believe that the loss of the right to use the service marks and related designs could have a material adverse effect on the Partnership’s business. The Management Agreement with PS provides that the Management Agreement may be terminated without cause upon 60 days written notice by the Partnership or six months notice by PS. During 2009, 2008 and 2007, the Partnership paid fees of $669,000, $689,000 and $675,000, respectively, to PS pursuant to the Management Agreement.

A real estate facility owned by the Partnership (the “Azusa Property”) is operated pursuant to a management and performance agreement (the “Performance Agreement”) with a subsidiary of PS (the “PS Sub”). Following the commencement of the Performance Agreement in March 2001, the facility was initially expanded to include industrial space, and this industrial space was subsequently converted to self-storage space. These improvements, along with any other subsequent improvements or capital expenditures during the term of the Performance Agreement, are entirely funded by the PS Sub. During the term of the Performance Agreement, the Partnership is guaranteed to receive the same net operating income it received with respect to the Azusa Property prior to the effective date of the Performance Agreement, with an annual increase of the greater of a) 1% or b) the percentage increase in net operating income achieved at the self-storage facilities managed by PS in the market in which this facility is located (the “Guaranteed Amounts”). The Performance Agreement expires on December 31, 2015, at which time the Partnership will commence collecting the actual net operating income currently earned by the PS Sub from operating the Azusa Property, and the Guaranteed Amounts will no longer apply. The PS Sub recorded revenues of $2,080,000, $2,037,000, and $1,663,000 in 2009, 2008, and 2007, respectively, and costs of operations (excluding depreciation) of $658,000, $659,000, and $733,000 in 2009, 2008, and 2007, respectively, with respect to the operation of the Azusa Property. Capital expenditures for the Azusa Property totaled $25,000, $7,000, and $16,000, in 2009, 2008, and 2007, respectively. Average occupancy of the Azusa Property was 88.2%, 84.7%, and 65.7% during 2009, 2008, and 2007, respectively. The lower average occupancies during 2008 and 2007 are primarily due to the fill-up of expanded self-storage space which was completed at the Azusa property, and paid for by the PS Sub, during 2006. Included in the line item “revenues from affiliate under performance agreement” in the Partnership’s accompanying statements of income, is the Guaranteed Amounts earned by the Partnership under the Performance Agreement. The Partnership recorded a total of $1,392,000, $1,334,000 and $1,274,000 in revenue with respect to the Performance Agreement for the years ended December 31, 2009, 2008 and 2007, respectively.

In addition, the Partnership combines its insurance purchasing power with PS through captive insurance entities controlled by PS (see Note 5 to the Partnership’s December 31, 2009 financial statements). These captive entities provide limited property and liability insurance to the Partnership at commercially competitive rates. The Partnership and PS also utilize unaffiliated insurance carriers to provide property and liability insurance in excess of the captive entities’ limitations. Premiums paid to the captive entities for the years ended December 31, 2009, 2008 and 2007 were $88,000, $103,000 and $88,000, respectively.

The Partnership’s facilities, along with facilities owned by PS and its affiliates, are managed and marketed jointly by PS in order to take advantage of scale and other efficiencies. Joint costs are allocated on a methodology meant to fairly allocate such costs based upon the related activities. As a result, significant components of cost of operations, such as payroll costs, advertising and promotion, data processing and insurance expenses are shared and allocated among the properties using methodologies meant to fairly allocate such costs based upon the related activities. The total of such expenses, substantially all of which are included in cost of operations on the Partnership’s statements of income, amounted to $1,652,000, $1,709,000, and $1,832,000 for the years ended December 31, 2009, 2008, and 2007, respectively. These expenses exclude amounts associated with the Azusa Property.

The Trustees of PS are identified in Item 10 on page 19 of this report.

ITEM 14. Principal Accountant Fees and Services

Fees billed to the Partnership by Ernst & Young LLP for 2009 and 2008 as are follows:

Audit Fees: Audit fees billed (or expected to be billed) to the Partnership by Ernst & Young LLP for the audit of the Partnership’s annual financial statements and reviews of the quarterly financial statements included in the Partnership’s quarterly reports on Form 10-Q totaled $19,000 for each of the years ended December 31, 2009 and 2008.

Tax Fees: Tax fees billed to the Partnership by Ernst & Young LLP for tax services (primarily federal and state income tax preparation) totaled $13,000 for each of the years ended December 31, 2009 and 2008.

Audit-Related Fees and Other Fees: During 2009 and 2008 Ernst & Young LLP did not bill the Partnership for audit-related services or any other services, except audit services and tax services denoted above.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Partners

Public Storage Properties IV, Ltd.

We have audited the accompanying balance sheets of Public Storage Properties IV, Ltd. (the “Partnership”) as of December 31, 2009 and 2008, and the related statements of income, partners' equity and cash flows for each of the three years in the period ended December 31, 2009. Our audits also included the financial statement schedule listed in the Index at Item 15(a). These financial statements and financial statement schedule are the responsibility of the Partnership's management. Our responsibility is to express an opinion on these financial statements and financial statement schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Partnership’s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Partnership’s internal control over financial reporting. Accordingly we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Public Storage Properties IV, Ltd. at December 31, 2009 and 2008, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2009, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set forth therein.

NOTES TO FINANCIAL STATEMENTS

December 31, 2009

1.	Description of Partnership

Public Storage Properties IV, Ltd., (the "Partnership") is a publicly held limited partnership formed under the California Uniform Limited Partnership Act in December 1977. The Partnership raised $20,000,000 in gross proceeds by selling 40,000 units of limited partnership interest ("Units") in an interstate offering, which commenced in May 1978 and completed in November 1978. The general partners in the Partnership are Public Storage, formerly Public Storage, Inc., (“PS”) and B. Wayne Hughes (“Hughes”).

The Partnership was formed to engage in the business of developing and operating self-storage facilities for personal and business use. The Partnership owns 17 self-storage facilities located in California and Florida.

2.	Summary of Significant Accounting Policies and Partnership Matters

Use of Estimates:

The preparation of financial statements in conformity with United States (“U.S.”) generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Revenue and Expense Recognition:

Rental income, which is generally earned pursuant to month-to-month leases for storage space, is recognized as earned. Promotional discounts are recognized as a reduction to rental income over the promotional period, which is generally during the first month of occupancy. Late charges and administrative fees are recognized as income when collected. Interest income is recognized as earned.

We accrue for property tax expense based upon actual amounts billed for the related time periods and, in some circumstances due to taxing authority assessment and billing timing and disputes of assessed amounts, estimates and historical trends. If these estimates are incorrect, the timing and amount of expense recognition could be affected. Cost of operations, general and administrative expense, as well as television, yellow page, and other advertising expenditures are expensed as incurred. Casualty losses or gains are recognized in the period the casualty occurs, based upon the differential between the book value of assets destroyed, and estimated insurance proceeds, if any, that we expect to receive in accordance with our insurance contracts.

Allocation of Net Income:

The general partners' share of net income consists of amounts attributable to their 1% capital contribution and an additional percentage of cash flow (as defined) which relates to the general partners' share of cash distributions as set forth in the Partnership Agreement (Note 4). All remaining net income is allocated to the limited partners.

Per unit data is based on the weighted average number of the limited partnership units (40,000) outstanding during the period.

PUBLIC STORAGE PROPERTIES IV, LTD.

NOTES TO FINANCIAL STATEMENTS

December 31, 2009

Financial Instruments:

The Partnership has estimated the fair value of our financial instruments using available market information and appropriate valuation methodologies. Considerable judgment is required in interpreting market data to develop estimates of market value. Accordingly, estimated fair values are not necessarily indicative of the amounts that could be realized in current market exchanges.

For purposes of financial statement presentation, we consider all highly liquid financial instruments such as short-term treasury securities, money market funds with daily liquidity and a rating of at least AAA by Standard and Poor’s, or investment grade (rated A1 by Standard and Poor’s) short-term commercial paper with remaining maturities of three months or less at the date of acquisition to be cash equivalents.

Due to the short maturity and the underlying characteristics of our cash and cash equivalents, other assets, accrued and other liabilities, and due to affiliate, we believe the carrying values as presented on the balance sheets are reasonable estimates of fair value.

Financial assets that are exposed to credit risk consist primarily of cash and cash equivalents as well as rent and other receivables. Cash and cash equivalents, as described above, are only invested in instruments with an investment grade rating. Our receivables consist of small individual amounts. Accordingly, credit risk on these assets as a whole is minimal.

Real Estate Facilities and Evaluation of Asset Impairment:

Real estate facilities are recorded at cost. Costs associated with the development, construction, renovation and improvement of properties are capitalized. Interest, property taxes, and other costs associated with the development incurred during the construction period are capitalized as building cost. Expenditures for repairs and maintenance are expensed when incurred. Depreciation expense is computed using the straight-line method over the estimated useful lives of the buildings and improvements, which generally range from 5 to 25 years. At December 31, 2009, all of the real estate facilities have been in service longer than 25 years, and accordingly the original development costs of such buildings are fully depreciated.

We evaluate our real estate for impairment on a quarterly basis. We first evaluate these assets for indicators of impairment, and if any indicators of impairment are noted, we determine whether the carrying value of the real estate is in excess of the future estimated undiscounted cash flows attributable to the real estate. If there is excess carrying value over such future undiscounted cash flows, an impairment charge is booked for the excess of carrying value over the real estate’s estimated fair value. Any real estate facility which we expect to sell or otherwise dispose of prior to its estimated useful life is stated at the lower of its estimated net realizable value (estimated fair value less cost to sell) or its carrying value. No impairment was identified from our evaluations in any periods presented in the accompanying financial statements.

Deferred Revenue:

Deferred revenue totaling $289,000 at December 31, 2009 ($297,000 at December 31, 2008), consists of prepaid rents, which are recognized as rental income when earned.

Environmental Cost:

The Partnership’s policy is to accrue environmental assessments and/or remediation costs when it is probable that such efforts will be required and the related costs can be reasonably estimated. Although there can be no assurance, we are not aware of any environmental contamination at any of our facilities, which, individually or in the aggregate, would be material to our overall business, financial condition or results of operations.

NOTES TO FINANCIAL STATEMENTS

December 31, 2009

Income Taxes:

Public Storage Properties IV, Ltd. is treated as a partnership for federal and state income tax purposes with the taxable income of the entity allocated to each partner in accordance with the Partnership Agreement. Accordingly, no federal income tax expense is recorded by the Partnership.

Recent Accounting Pronouncements and Guidance:

As of March 25, 2010, there have been no recent accounting pronouncements and guidance, which were not effective for implementation prior to December 31, 2009, that would have a material impact upon reporting the operations or financial position of the Partnership.

Segment Reporting:

The Partnership only has one reportable segment.

3.	Cash Distributions

The Partnership Agreement requires that cash available for distribution (cash flow from all sources less cash necessary for any obligations or capital improvements) be distributed at least quarterly. During the year ended December 31, 2009, we paid distributions to the limited and general partners totaling $7,280,000 ($182.00 per unit) and $2,525,000, respectively. During the year ended December 31, 2008, we paid distributions to the limited and general partners totaling $6,680,000 ($167.00 per unit) and $2,317,000, respectively. During the year ended December 31, 2007, we paid distributions to the limited and general partners totaling $8,000,000 ($200.00 per unit) and $2,774,000, respectively. Future distribution rates may be adjusted to levels, which are supported by operating cash flow after provisions for capital improvements and any other obligations.

4.	Partners' Equity

PS and Hughes are general partners of the Partnership. In 1995, Hughes contributed his ownership and rights to distributions from the Partnership to BWH Marina Corporation II, a corporation wholly-owned by Hughes. As such, Mr. Hughes continues to act as a general partner but receives no direct compensation, or other consideration from the Partnership.

The general partners have a 1% interest in the Partnership. In addition, the general partners have 8% interest in cash distributions attributable to operations (exclusive of distributions attributable to sale and financing proceeds) until the limited partners recover all of their initial investment. Thereafter, the general partners have a 25% interest in all cash distributions (including sale and financing proceeds). In 1986, the limited partners recovered all of their initial investment. All subsequent cash distributions are being made 25.75% (including the 1% interest) to the general partners and 74.25% to the limited partners. Transfers of equity are made periodically to reconcile the partners’ equity accounts to the provisions of the Partnership Agreement. These transfers have no effect on the results of operations or distributions to partners.

5. Related Party Transactions

Management Agreements and Shared Expenses with Affiliates

The Partnership has a management agreement (the “Management Agreement”) with PS pursuant to which PS operates the self-storage facilities for a fee equal to 6% of the facilities' gross revenue (as defined). For 2009, 2008 and 2007, the Partnership paid PS $669,000, $689,000 and $675,000, respectively, pursuant to this Management Agreement.

A real estate facility owned by the Partnership (the “Azusa Property”) is operated pursuant to a management and performance agreement (the “Performance Agreement”) with a subsidiary of PS (the “PS Sub”). Following the commencement of the Performance Agreement in March 2001, the facility was initially expanded to include industrial space, and this industrial space was subsequently converted to self-storage space. These improvements, along with any other subsequent improvements or capital expenditures during the term of the Performance Agreement, are entirely funded by the PS Sub. During the term of the Performance Agreement, the Partnership is guaranteed to receive the same net operating income it received with respect to the Azusa Property prior to the effective date of the Performance Agreement, with an annual increase of the greater of a) 1% or b) the percentage increase in net operating income achieved at the self-storage facilities managed by PS in the market in which this facility is located (the “Guaranteed Amounts”). The Performance Agreement expires on December 31, 2015, at which time the Partnership will commence collecting the actual net operating income currently earned by the PS Sub from operating the Azusa Property, and the Guaranteed Amounts will no longer apply. The PS Sub recorded revenues of $2,080,000, $2,037,000, and $1,663,000 in 2009, 2008, and 2007, respectively, and costs of operations (excluding depreciation) of $658,000, $659,000, and $733,000 in 2009, 2008, and 2007, respectively, with respect to the operation of the Azusa Property. Capital expenditures totaled $25,000, $7,000, and $16,000, in 2009, 2008, and 2007, respectively. Average occupancy of the Azusa Property was 88.2%, 84.7%, and 65.7% during 2009, 2008, and 2007, respectively. The lower average occupancies during 2008 and 2007 are primarily due to the fill-up of expanded self-storage space which was completed at the Azusa Property, and paid for by the PS Sub, during 2006. Included in the line item “revenues from affiliate under performance agreement” in the Partnership’s accompanying statements of income, is the Guaranteed Amounts earned by the Partnership under the Performance Agreement. The Partnership recorded a total of $1,392,000, $1,334,000 and $1,274,000 in revenue with respect to the Performance Agreement for the years ended December 31, 2009, 2008 and 2007, respectively.

The Partnership’s facilities, along with facilities owned by PS and its affiliates, are managed and marketed jointly by PS in order to take advantage of scale and other efficiencies. Joint costs are allocated on a methodology meant to fairly allocate such costs based upon the related activities. As a result, significant components of cost of operations, such as payroll costs, advertising and promotion, data processing and insurance expenses are shared and allocated among the properties using methodologies meant to fairly allocate such costs based upon the related activities. The total of such expenses, substantially all of which are included in cost of operations in our accompanying statements of income, amounted to $1,652,000, $1,709,000, and $1,832,000 for the years ended December 31, 2009, 2008 and 2007, respectively. These expenses exclude amounts associated with the Azusa Property.

Ownership of Limited Partnership Interest by the General Partners

PS owns 11,365 Limited Partnership Units (“Units”), as to which PS has sole voting and dispositive power.

PUBLIC STORAGE PROPERTIES IV, LTD.

NOTES TO FINANCIAL STATEMENTS

December 31, 2009

At December 31, 2008, Hughes and members of his family (the “Hughes Family”) owned 6,198 Units. Hughes owned 5,892 Units, as to which Hughes had sole voting and dispositive power, through a wholly-owned corporation and Tamara Hughes Gustavson, an adult daughter of Hughes, owned 306 Units as to which Tamara Hughes Gustavson had sole voting and dispositive power. On January 1, 2009, PS exercised its option to acquire 306 of the Units held by Tamara Hughes Gustavson for a cost of approximately $136,000. At December 31, 2009, Hughes owns 5,892 Units.

In addition, there are 7,299 Units owned by PS Orangeco Partnerships, Inc., a corporation in which the Hughes Family owns approximately 48% of the voting stock, PS owns 46% and members of PS management and related individuals own approximately 6%.

Captive Insurance Activities with PS

The Partnership has a 1.8% ownership interest in STOR-Re Mutual Insurance Corporation (“STOR-Re”), which was formed in 1994 as an association captive insurance company, and is controlled by PS. The Partnership accounts for its investment in STOR-Re, which is included in other assets on our accompanying balance sheets, on the cost method, and has received no distributions during the three years ended December 31, 2009.

STOR-Re provides limited property and liability insurance coverage to the Partnership, PS, and affiliates for losses occurring before April 1, 2004. STOR-Re was succeeded with respect to these activities for losses occurring after March 31, 2004 by a wholly owned subsidiary of PS (collectively, this entity and STOR-Re are referred to as the “Captive Entities”). Liabilities for losses and loss adjustment expenses include an amount determined from loss reports and individual cases and an amount, based on recommendations from an outside actuary that is a member of the American Academy of Actuaries, using a frequency and severity method, for losses incurred but not reported. Determining the liability for unpaid losses and loss adjustment expense is based upon estimates and while we believe that the amount is adequate, the ultimate loss may be in excess of or less than the amounts provided. The methods for making such estimates and for establishing the resulting liability are reviewed quarterly.

The following table sets forth certain condensed consolidated financial information (unaudited) with respect to STOR-Re (representing 100% of this entity’s operations and not the Partnership’s pro-rata share):

	2009			2008
	(Amounts in thousands)

Other Activities with PS

PS Insurance Company – Hawaii, Ltd. (“PSICH”), is a corporation owned by PS that reinsures policies against losses to goods stored by tenants in the Partnership’s and PS’ storage facilities. PSICH receives the premiums and bears the risks associated with the re-insurance. The Partnership receives a fee (an “Access Fee”) from PSICH in return for providing tenant listings. This Access Fee is based on the number of spaces the Partnership has to rent. Included in other income on our accompanying statements of income for these Access Fees are $374,000, $412,000 and $199,000 for the years ended December 31, 2009, 2008 and 2007, respectively.

A subsidiary of PS sells locks and boxes to the general public and tenants to be used in securing their spaces and moving their goods. The subsidiary of PS receives the revenues and bears the cost of the activities.

Due to Affiliate

6. Taxes Based on Income

Taxes based on income are the responsibility of the individual partners and, accordingly, the Partnership's financial statements do not reflect a provision for such taxes.

Taxable net income (unaudited) was $8,401,000, $9,113,000 and $8,715,000 for the years ended December 31, 2009, 2008 and 2007 respectively. The difference between taxable net income and net income is primarily related to depreciation expense resulting from differences in depreciation and capitalization methodologies.
