Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION AND NATURE OF OPERATIONS	ORGANIZATION AND NATURE OF OPERATIONS National Storage Affiliates Trust was organized in the state of Maryland on May 16, 2013 and is a fully integrated, self-administered and self-managed real estate investment trust focused on the self storage sector. As used herein, "NSA," the "Company," "we," "our," and "us" refers to National Storage Affiliates Trust and its consolidated subsidiaries, except where the context indicates otherwise. The Company has elected and believes that it has qualified to be taxed as a real estate investment trust for U.S. federal income tax purposes ("REIT") commencing with its taxable year ended December 31, 2015. Through its controlling interest as the sole general partner of NSA OP, LP (its "operating partnership"), a Delaware limited partnership formed on February 13, 2013, the Company is focused on the ownership, operation, and acquisition of self storage properties located within the top 100 MSAs in the United States. Pursuant to the Agreement of Limited Partnership (as amended, the "LP Agreement") of its operating partnership, the Company's operating partnership is authorized to issue preferred units, Class A Units ("OP units"), different series of Class B Units ("subordinated performance units"), and Long-Term Incentive Plan Units ("LTIP units"). The Company also owns certain of its self storage properties through other consolidated limited partnership subsidiaries of its operating partnership, which the Company refers to as "DownREIT partnerships." The DownREIT partnerships issue equity ownership interests that are intended to be economically equivalent to the Company's OP units ("DownREIT OP units") and subordinated performance units ("DownREIT subordinated performance units"). The Company owned 567 consolidated self storage properties in 29 states and Puerto Rico with approximately 34.5 million rentable square feet (unaudited) in approximately 275,000 storage units as of December 31, 2019. These properties are managed with local operational focus and expertise by the Company and its participating regional operators ("PROs"). These PROs are SecurCare Self Storage, Inc. and its controlled affiliates ("SecurCare"), Kevin Howard Real Estate Inc., d/b/a Northwest Self Storage and its controlled affiliates ("Northwest"), Optivest Properties LLC and its controlled affiliates ("Optivest"), Guardian Storage Centers LLC and its controlled affiliates ("Guardian"), Move It Self Storage and its controlled affiliates ("Move It"), Arizona Mini Storage Management Company d/b/a Storage Solutions and its controlled affiliates ("Storage Solutions"), Hide-Away Storage Services, Inc. and its controlled affiliates ("Hide-Away"), an affiliate of Shader Brothers Corporation d/b/a Personal Mini Storage ("Personal Mini"), Southern Storage Management Systems, Inc. d/b/a Southern Self Storage ("Southern") and affiliates of Investment Real Estate Management, LLC d/b/a Moove In Self Storage ("Moove In"). As of December 31, 2019, the Company also managed through its property management platform an additional portfolio of 175 properties owned by the Company's unconsolidated real estate ventures. These properties contain approximately 12.6 million rentable square feet, configured in approximately 103,000 storage units and located across 21 states. The Company owns a 25% equity interest in each of its unconsolidated real estate ventures. As of December 31, 2019, in total, the Company operated and held ownership interests in 742 self storage properties located across 35 states and Puerto Rico with approximately 47.1 million rentable square feet in approximately 378,000 storage units.

SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying consolidated financial statements are presented on the accrual basis of accounting in accordance with U.S. generally accepted accounting principles ("GAAP"). Principles of Consolidation The Company's consolidated financial statements include the accounts of its operating partnership and its controlled subsidiaries. All significant intercompany balances and transactions have been eliminated in the consolidation of entities. When the Company obtains an economic interest in an entity, the Company evaluates the entity to determine if the entity is deemed a variable interest entity ("VIE"), and if the Company is deemed to be the primary beneficiary, in accordance with authoritative guidance issued on the consolidation of VIEs. When an entity is not deemed to be a VIE, the Company considers the provisions of additional guidance to determine whether the general partner controls a limited partnership or similar entity when the limited partners have certain rights. The Company consolidates all entities that are VIEs and of which the Company is deemed to be the primary beneficiary. The Company has determined that its operating partnership is a VIE. The sole significant asset of National Storage Affiliates Trust is its investment in its operating partnership, and consequently, substantially all of the Company's assets and liabilities represent those assets and liabilities of its operating partnership. As of December 31, 2019, the Company's operating partnership was the primary beneficiary of, and therefore consolidated, 21 DownREIT partnerships that are considered VIEs, which owned 34 self storage properties. The net book value of the real estate owned by these VIEs was $233.1 million and $240.4 million as of December 31, 2019 and December 31, 2018, respectively. For certain DownREIT partnerships which are subject to fixed rate mortgages payable, the carrying value of such fixed rate mortgages payable held by these VIEs was $136.4 million and $138.4 million as of December 31, 2019 and December 31, 2018, respectively. The creditors of the consolidated VIEs do not have recourse to the Company's general credit. Noncontrolling Interests All of the limited partner equity interests ("OP equity") in its operating partnership not held by the Company are reflected as noncontrolling interests. Noncontrolling interests also include ownership interests in DownREIT partnerships held by entities other than the Company's operating partnership. In the consolidated statements of operations, the Company allocates net income (loss) attributable to noncontrolling interests to arrive at net income (loss) attributable to National Storage Affiliates Trust. For transactions that result in changes to the Company's ownership interest in its operating partnership, the carrying amount of noncontrolling interests is adjusted to reflect such changes. The difference between the fair value of the consideration received or paid and the amount by which the noncontrolling interests is adjusted is reflected as an adjustment to additional paid-in capital on the consolidated balance sheets. Self Storage Properties Self storage properties are carried at historical cost less accumulated depreciation and any impairment losses. Major replacements and betterments, which improve or extend the life of an asset, are capitalized. Expenditures for ordinary repairs and maintenance are expensed as incurred and are included in property operating expenses. Estimated depreciable lives of self storage properties are determined by considering the age and other indicators about the condition of the assets at the respective dates of acquisition, resulting in a range of estimated useful lives for assets within each category. All self storage property assets are depreciated using the straight-line method. Buildings and improvements are depreciated over estimated useful lives primarily between seven three When a self storage property is acquired, the purchase price of the acquired self storage property is allocated to land, buildings and improvements, furniture and equipment, customer in-place leases, assumed real estate leasehold interests, and other assets acquired and liabilities assumed, based on the estimated fair value of each component. When a portfolio of self storage properties is acquired, the purchase price is allocated to the individual self storage properties based on the fair value determined using an income approach with appropriate risk-adjusted capitalization rates, which take into account the relative size, age and location of the individual self storage properties. Cash and Cash Equivalents The Company considers all highly-liquid investments purchased with original maturities of three months or less to be cash equivalents. From time to time, the Company maintains cash balances in financial institutions in excess of federally insured limits. The Company has never experienced a loss that resulted from exceeding federally insured limits. Restricted Cash The Company's restricted cash consists of escrowed funds deposited with financial institutions for real estate taxes, insurance and other reserves for capital improvements in accordance with the Company's loan agreements. Customer In-place Leases In allocating the purchase price for a self storage property acquisition, the Company determines whether the acquisition includes intangible assets. The Company allocates a portion of the purchase price to an intangible asset attributed to the value of customer in-place leases. This intangible asset is amortized to expense using the straight-line method over 12 months, the estimated average rental period for the leases. Substantially all of the leases in place at acquired properties are at market rates, as the leases are month-to-month contracts. Impairment of Long-Lived Assets The Company evaluates long-lived assets for impairment when events and circumstances indicate that there may be impairment. When events or changes in circumstances indicate that the Company's long-lived assets may not be recoverable, the carrying value of these long-lived assets is compared to the undiscounted future net operating cash flows, plus a terminal value attributable to the assets. If an asset's carrying value is not considered recoverable, an impairment loss is recorded to the extent the net carrying value of the asset exceeds the fair value. For the periods presented, no assets were determined to be impaired under this policy. Costs of Raising Capital Commissions, legal fees and other costs that are directly associated with equity offerings are capitalized as deferred offering costs, pending a determination of the success of the offering. Deferred offering costs related to successful offerings are charged to additional paid-in capital within equity in the period it is determined that the offering was successful. Debt issuance costs are amortized over the estimated life of the related debt using the straight-line method, which approximates the effective interest rate method. Amortization of debt issuance costs is included in interest expense in the accompanying statements of operations. Revenue Recognition Rental revenue Rental revenue consists of space rentals and related fees. Management has determined that all of the Company's leases are operating leases. Substantially all leases may be terminated on a month-to-month basis and rental income is recognized ratably over the lease term using the straight-line method. Rents received in advance are deferred and recognized on a straight-line basis over the related lease term associated with the prepayment. Promotional discounts and other incentives are recognized as a reduction to rental income over the applicable lease term. Other property-related revenue Other property-related revenue primarily consists of ancillary revenues such as tenant insurance and/or tenant warranty protection-related access fees and sales of storage supplies which are recognized in the period earned. The Company and certain of the Company’s PROs have tenant insurance- and/or tenant warranty protection plan-related arrangements with insurance companies and the Company’s tenants. During the years ended December 31, 2019, 2018 and 2017, the Company recognized $9.1 million, $7.5 million and $6.0 million, respectively, of tenant insurance and tenant warranty protection plan revenues. The Company sells boxes, packing supplies, locks and other retail merchandise at its properties. During the years ended December 31, 2019, 2018 and 2017, the Company recognized retail sales of $1.7 million, $1.5 million and $1.3 million, respectively. Management fees and other revenue Management fees and other revenue consist of property management fees, platform fees, call center fees, acquisition fees, and a portion of tenant warranty protection or tenant insurance proceeds that the Company earns for managing and operating its unconsolidated real estate ventures. With respect to both the 2018 Joint Venture and the 2016 Joint Venture, the Company provides supervisory and administrative property management services, centralized call center services, and technology platform and revenue management services to the properties in the unconsolidated real estate ventures. The property management fees are equal to 6% of monthly gross revenues and net sales revenues from the assets of the unconsolidated real estate ventures, and the platform fees are equal to $1,250 per month per unconsolidated real estate venture property. With respect to the 2016 Joint Venture only, the call center fees are equal to 1% of each of monthly gross revenues and net sales revenues from the 2016 Joint Venture properties. During the years ended December 31, 2019, 2018 and 2017, the Company recognized property management fees, call center fees and platform fees of $12.8 million, $7.8 million and $4.8 million, respectively. For acquisition fees, the Company provides sourcing, underwriting and administration services to the unconsolidated real estate ventures. The 2016 Joint Venture paid the Company a $4.1 million acquisition fee equal to 0.65% of the gross capitalization (including debt and equity) of the original 66-property 2016 Joint Venture portfolio (the "Initial 2016 JV Portfolio") in 2016, at the time of the Initial 2016 JV Portfolio acquisition. The 2018 Joint Venture paid the Company a $4.0 million acquisition fee related to the initial acquisition of properties by the 2018 Joint Venture (the "Initial 2018 JV Portfolio") during the year ended December 31, 2018, at the time of the Initial 2018 JV Portfolio acquisition. These fees are refundable to the unconsolidated real estate ventures, on a prorated basis, if the Company is removed as the managing member during the initial four four The Company also earns acquisition fees for properties acquired by the unconsolidated real estate ventures subsequent to the Initial 2016 JV Portfolio and the Initial 2018 JV Portfolio. These fees are based on a percentage of the gross capitalization of the acquired assets determined by the members of the 2016 Joint Venture and the 2018 Joint Venture, and are generally earned when the unconsolidated real estate ventures obtain title and control of an acquired property. During the years ended December 31, 2019, 2018 and 2017, the Company recognized acquisition fees of $1.8 million, $1.6 million and $1.5 million, respectively. An affiliate of the Company facilitates tenant warranty protection or tenant insurance programs for tenants of the properties in the unconsolidated real estate ventures in exchange for 50% of all proceeds from such programs at each unconsolidated real estate venture property. During the years ended December 31, 2019, 2018 and 2017, the Company recognized $4.7 million, $2.4 million and $1.9 million, respectively, of revenue related to these activities. Advertising Costs The Company incurs advertising costs primarily attributable to internet, directory and other advertising. Advertising costs are included in property operating expenses in the accompanying statements of operations. These costs are expensed in the period in which the cost is incurred. The Company incurred advertising costs of $5.2 million, $4.1 million and $3.7 million for the years ended December 31, 2019, 2018 and 2017, respectively. Acquisition Costs The Company incurs title, legal and consulting fees, and other costs associated with the completion of acquisitions. During the year ended December 31, 2017, the Company adopted Accounting Standards Update ("ASU") 2017-01 and as a result, the Company's self storage property acquisitions during the years ended December 31, 2019 and 2018 were accounted for as asset acquisitions, and accordingly, acquisition costs directly related to the self storage property acquisitions were capitalized as part of the basis of the acquired properties. Indirect acquisition costs remain included in acquisition costs in the accompanying statements of operations in the period in which they were incurred. Prior to the Company's adoption of ASU 2017-01, direct and indirect costs were included in acquisition costs in the accompanying statements of operations in the period in which they were incurred. Income Taxes The Company has elected and believes it has qualified to be taxed as a REIT under sections 856 through 860 of the U.S. Internal Revenue Code (the "Code") commencing with the taxable year ended December 31, 2015. To qualify as a REIT, among other things, the Company is required to distribute at least 90% of its REIT taxable income to its shareholders and meet certain tests regarding the nature of its income and assets. As a REIT, the Company is not subject to federal income tax on the earnings distributed currently to its shareholders that it derives from its REIT qualifying activities. If the Company fails to qualify as a REIT in any taxable year, and is unable to avail itself of certain provisions set forth in the Code, all of the Company's taxable income would be subject to federal and state income taxes at regular corporate rates. The Company will not be required to make distributions with respect to income derived from the activities conducted through subsidiaries that the Company elects to treat as taxable REIT subsidiaries ("TRS") for federal income tax purposes. Certain activities that the Company undertakes must be conducted by a TRS, such as performing non-customary services for its customers, facilitating sales by PROs of tenant insurance and holding assets that the Company is not permitted to hold directly. A TRS is subject to federal and state income taxes. On June 25, 2014, the Company formed NSA TRS, LLC ("NSA TRS"), a Delaware limited liability company. The Company has elected to treat NSA TRS as a TRS, and consequently, NSA TRS is subject to U.S. federal and state corporate income taxes. Deferred tax assets and liabilities are recognized to the extent of any differences between the financial reporting and tax bases of assets and liabilities. No material deferred tax assets and liabilities were recorded as of December 31, 2019 and 2018. The Company did not have any unrecognized tax benefits related to uncertain tax positions as of December 31, 2019 and 2018. Future amounts of accrued interest and penalties, if any, related to uncertain tax positions will be recorded as a component of income tax expense. The Company does not expect that the amount of unrecognized tax benefits will change significantly in the next 12 months. The Company's material taxing jurisdiction is the U.S. federal jurisdiction; the 2016 tax year is the earliest period that remains open to examination by these taxing jurisdictions. Earnings per Share Basic earnings per share is calculated based on the weighted average number of the Company's common shares of beneficial interest, $0.01 par value per share ("common shares"), outstanding during the period. Diluted earnings per share is calculated by further adjusting for the dilutive impact using the treasury stock method for any share options and unvested share equivalents outstanding during the period and the if-converted method for any convertible securities outstanding during the period. As more fully described below under " –Allocation of Net Income (Loss)" , the Company allocates GAAP income (loss) utilizing the hypothetical liquidation at book value ("HLBV") method, which could result in net income (or net loss) attributable to National Storage Affiliates Trust during a period when the Company reports consolidated net loss (or net income), or net income (or net loss) attributable to National Storage Affiliates Trust in excess of the Company's consolidated net income (or net loss). The computations of basic and diluted earnings (loss) per share may be materially affected by these disproportionate income (loss) allocations, resulting in volatile fluctuations of basic and diluted earnings (loss) per share. Equity-Based Awards The measurement and recognition of compensation cost for all equity-based awards granted to officers, employees and consultants is based on estimated fair values. Compensation cost is recognized on a straight-line basis over the requisite service periods of each award with non-graded vesting. For awards granted which contain a graded vesting schedule and the only condition for vesting is a service condition, compensation cost is recognized as an expense on a straight-line basis over the requisite service period as if the award was, in substance, a single award. For awards granted for which vesting is subject to a performance condition, compensation cost is recognized over the requisite service period if and when the Company concludes it is probable that the performance condition will be achieved. The estimated fair value of all equity-based awards issued to PROs and their affiliates in connection with self storage property acquisitions is included in the cost of the respective acquisitions. The estimated fair value of such awards is measured at the date the self storage properties are acquired, as this date represents satisfaction of the performance condition and coincides with the award vesting. Derivative Financial Instruments The Company carries all derivative financial instruments on the balance sheet at fair value. Fair value of derivatives is determined by reference to observable prices that are based on inputs not quoted on active markets, but corroborated by market data. The accounting for changes in the fair value of a derivative instrument depends on whether the derivative has been designated and qualifies as part of a hedging relationship. The Company's use of derivative instruments has been limited to interest rate swap and cap agreements. The fair values of derivative instruments are included in other assets and accounts payable and accrued liabilities in the accompanying balance sheets. For derivative instruments not designated as cash flow hedges, the unrealized gains and losses are included in interest expense in the accompanying statements of operations. For derivatives designated as cash flow hedges, the effective portion of the changes in the fair value of the derivatives is initially reported in accumulated other comprehensive income (loss) in the Company's balance sheets and subsequently reclassified into earnings when the hedged transaction affects earnings. The valuation of interest rate swap and cap agreements is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves. The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts are based on an expectation of future interest rates (forward curves) derived from observable market interest rate forward curves. The Company may enter into derivative contracts that are intended to economically hedge certain of its risk, even though hedge accounting does not apply or the Company elects not to apply hedge accounting. Fair Value Measurements When measuring fair value of financial instruments that are required to be recorded or disclosed at fair value, the Company uses a three-tier measurement hierarchy which prioritizes the inputs used to calculate fair value. These tiers include Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. Investments in Unconsolidated Real Estate Ventures The Company’s investments in its unconsolidated real estate ventures are recorded under the equity method of accounting in the accompanying consolidated financial statements. Under the equity method, the Company’s investments in unconsolidated real estate ventures are stated at cost and adjusted for the Company’s share of net earnings or losses and reduced by distributions. Equity in earnings (losses) is recognized based on the Company’s ownership interest in the earnings (losses) of the unconsolidated real estate ventures. The Company follows the "nature of the distribution approach" for classification of distributions from its unconsolidated real estate ventures in its consolidated statements of cash flows. Under this approach, distributions are reported on the basis of the nature of the activity or activities that generated the distributions as either a return on investment, which are classified as operating cash flows, or a return of investment (e.g., proceeds from the unconsolidated real estate ventures' sale of assets) which are reported as investing cash flows. Segment Reporting The Company manages its business as one reportable segment consisting of investments in self storage properties located in the United States. Although the Company operates in several markets, these operations have been aggregated into one reportable segment based on the similar economic characteristics among all markets. Allocation of Net Income (Loss) The distribution rights and priorities set forth in the operating partnership's LP Agreement differ from what is reflected by the underlying percentage ownership interests of the operating partnership's unitholders. Accordingly, the Company allocates GAAP income (loss) utilizing the HLBV method, in which the Company allocates income or loss based on the change in each unitholders’ claim on the net assets of its operating partnership at period end after adjusting for any distributions or contributions made during such period. The HLBV method is commonly applied to equity investments where cash distribution percentages vary at different points in time and are not directly linked to an equity holder’s ownership percentage. The HLBV method is a balance sheet-focused approach to income (loss) allocation. A calculation is prepared at each balance sheet date to determine the amount that unitholders would receive if the operating partnership were to liquidate all of its assets (at GAAP net book value) and distribute the resulting proceeds to its creditors and unitholders based on the contractually defined liquidation priorities. The difference between the calculated liquidation distribution amounts at the beginning and the end of the reporting period, after adjusting for capital contributions and distributions, is used to derive each unitholder's share of the income (loss) for the period. Due to the stated liquidation priorities and because the HLBV method incorporates non-cash items such as depreciation expense, in any given period, income or loss may be allocated disproportionately to unitholders as compared to their respective ownership percentage in the operating partnership, and net income (loss) attributable to National Storage Affiliates Trust could be more or less net income than actual cash distributions received and more or less income or loss than what may be received in the event of an actual liquidation. Additionally, the HLBV method could result in net income (or net loss) attributable to National Storage Affiliates Trust during a period when the Company reports consolidated net loss (or net income), or net income (or net loss) attributable to National Storage Affiliates Trust in excess of the Company's consolidated net income (or net loss). The computations of basic and diluted earnings (loss) per share may be materially affected by these disproportionate income (loss) allocations, resulting in volatile fluctuations of basic and diluted earnings (loss) per share. Other Comprehensive Income (Loss) The Company has cash flow hedge derivative instruments that are measured at fair value with unrealized gains or losses recognized in other comprehensive income (loss) with a corresponding adjustment to accumulated other comprehensive income (loss) within equity, as discussed further in Note 14. Under the HLBV method of allocating income (loss) discussed above, a calculation is prepared at each balance sheet date by applying the HLBV method including, and excluding, the assets and liabilities resulting from the Company's cash flow hedge derivative instruments to determine comprehensive income (loss) attributable to National Storage Affiliates Trust. As a result of the distribution rights and priorities set forth in the operating partnership's LP Agreement, in any given period, other comprehensive income (loss) may be allocated disproportionately to unitholders as compared to their respective ownership percentage in the operating partnership and as compared to their respective allocation of net income (loss). Gain on sale of self storage properties The Company recognizes gains from disposition of facilities only upon closing in accordance with the guidance on sales of nonfinancial assets. Profit on real estate sold is recognized upon closing when all, or substantially all, of the promised consideration has been received and is nonrefundable and the Company has transferred control of the facilities to the purchaser. Goodwill Goodwill represents the costs of business acquisitions in excess of the fair value of identifiable net assets acquired. The Company evaluates goodwill for potential impairment annually, or whenever impairment indicators are present. The Company determined that there was no impairment to goodwill during the years ended December 31, 2019 and 2018. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Recent Accounting Pronouncements In February 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-02, Leases, which amends the existing guidance for accounting for leases, including requiring lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases and lessees to recognize most leases on-balance sheet as lease liabilities with corresponding right-of-use assets. In July 2018, the FASB issued ASU 2018-11, Leases - Targeted Improvements, which allows entities the option to apply the new standard at adoption date with a cumulative-effect adjustment in the period of adoption. The Company adopted ASU 2016-02 and ASU 2018-11 effective January 1, 2019 and applied it to leases that were in place on the effective date. The Company elected the practical expedients which permit the Company to combine lease and nonlease components and to not reassess (i) whether any expired or existing contracts are or contain leases, (ii) the lease classification for any expired or existing leases, and (iii) any initial direct costs for any existing leases as of the effective date. Results for reporting periods beginning January 1, 2019 are presented under ASU 2016-02 and ASU 2018-11. As a result, beginning on January 1, 2019, activity related to uncollectible accounts are recognized as a current-period adjustment within revenue. For periods prior to January 1, 2019, such amounts were previously included in operating expenses. The adoption of the lease standard did not result in a cumulative catch-up adjustment to opening equity. See Note 13 for additional detail about the Company's non-cancelable leasehold interest agreements where the Company is a lessee.

SHAREHOLDERS' EQUITY AND NONCON

SHAREHOLDERS' EQUITY AND NONCONTROLLING INTERESTS	12 Months Ended
	Dec. 31, 2019
Equity [Abstract]
SHAREHOLDERS' EQUITY AND NONCONTROLLING INTERESTS	SHAREHOLDERS' EQUITY AND NONCONTROLLING INTERESTS Shareholders' Equity At the Market ("ATM") Program On February 27, 2019, the Company entered into a sales agreement with certain sales agents, pursuant to which the Company may sell from time to time up to $250.0 million of the Company's common shares and 6.000% Series A Preferred Shares in sales deemed to be "at the market" offerings. The sales agreement contemplates that, in addition to the issuance and sale by the Company of offered shares to or through the sale agents, the Company may enter into separate forward sale agreements with any forward purchaser. Forward sale agreements, if any, will include only the Company's common shares and will not include any Series A Preferred Shares. If the Company enters into a forward sale agreement with any forward purchaser, such forward purchaser will attempt to borrow from third parties and sell, through the related agent, acting as sales agent for such forward purchaser (each, a "forward seller"), offered shares, in an amount equal to the offered shares subject to such forward sale agreement, to hedge such forward purchaser’s exposure under such forward sale agreement. The Company may offer the common shares and Series A Preferred Shares through the agents, as the Company's sales agents, or, as applicable, as forward seller, or directly to the agents or forward sellers, acting as principals, by means of, among others, ordinary brokers’ transactions on the NYSE or otherwise at market prices prevailing at the time of sale or at negotiated prices. During the year ended December 31, 2019, the Company sold 2,375,000 of its common shares through the ATM program at an average offering price of $30.06 per share, resulting in net proceeds to the Company of approximately $70.6 million, after deducting compensation payable by the Company to such agents and offering expenses. In addition, during the year ended December 31, 2019, the Company sold 1,785,680 of its Series A Preferred Shares through the ATM program at an average offering price of $24.84 per share, resulting in net proceeds to the Company of approximately $43.6 million, after deducting compensation payable by the Company to such agents and offering expenses. Common Share Offerings On July 13, 2018, the Company closed a follow-on offering of 5,900,000 of its common shares at an offering price of $29.86 per share. The Company received aggregate net proceeds from the offering of approximately $175.6 million after deducting expenses associated with the offering. On December 11, 2017, the Company closed a follow-on public offering of 5,750,000 of its common shares, which included 750,000 common shares sold upon the exercise in full by the underwriters of their option to purchase additional common shares, at a public offering price of $25.50 per share. The Company received aggregate net proceeds from the offering of approximately $140.3 million after deducting the underwriting discount and additional expenses associated with the offering. Series A Preferred Share Offering On October 11, 2017, the Company completed an underwritten public offering of 6,900,000 of its 6.000% Series A Preferred Shares, which included 900,000 Series A Preferred Shares sold upon the exercise in full by the underwriters of their option to purchase additional Series A Preferred Shares, resulting in net proceeds to the Company of approximately $166.6 million, after deducting the underwriting discount and the Company's other offering expenses. Dividends on the Series A Preferred Shares, which are payable quarterly in arrears, are cumulative from the date of original issuance in the amount of $1.50 per share each year. The Series A Preferred Shares rank senior to the Company's common shares with respect to rights and rights upon our liquidation, dissolution or winding up. Generally, the Series A Preferred Shares become redeemable by the Company beginning in October 2022 for a cash redemption price of $25.00 per share, plus accrued but unpaid dividends. Noncontrolling Interests All of the OP equity in the Company's operating partnership not held by the Company is reflected as noncontrolling interests. Noncontrolling interests also include ownership interests in DownREIT partnerships held by entities other than the Company's operating partnership. NSA is the general partner of its operating partnership and is authorized to cause its operating partnership to issue additional partner interests, including OP units and subordinated performance units, at such prices and on such other terms as it determines in its sole discretion. As of December 31, 2019 and 2018, units reflecting noncontrolling interests consisted of the following: December 31, 2019 2018 Series A-1 preferred units 642,982 343,719 OP units 30,188,305 28,874,103 Subordinated performance units 11,014,195 10,749,475 LTIP units 743,566 931,671 DownREIT units DownREIT OP units 1,848,261 1,834,786 DownREIT subordinated performance units 4,371,622 4,386,999 Total 48,808,931 47,120,753 Series A-1 Preferred Units The 6.000% Series A-1 Cumulative Redeemable Preferred Units ("Series A-1 preferred units") rank senior to OP units and subordinated performance units in the Company's operating partnership with respect to distributions and liquidation. The Series A-1 preferred units have a stated value of $25.00 per unit and receive distributions at an annual rate of 6.000%. These distributions are cumulative. The Series A-1 preferred units are redeemable at the option of the holder after the first anniversary of the date of issuance, which redemption obligations may be satisfied at the Company’s option in cash in an amount equal to the market value of an equivalent number of the Company's 6.000% Series A Preferred Shares or the issuance of 6.000% Series A Preferred Shares on a one-for-one basis, subject to adjustments. Generally, the Series A-1 preferred units become redeemable by the Company beginning ten years after the initial issuance of each Series A-1 preferred unit at a stated value of $25.00 per unit, plus accrued but unpaid distributions. The increase in Series A-1 preferred units outstanding from December 31, 2018 to December 31, 2019 was due to the issuance of Series A-1 preferred units in connection with the acquisition of self storage properties partially offset by the redemption of 41,439 Series A-1 preferred units for Series A preferred shares. OP Units and DownREIT OP units OP units in the Company's operating partnership are redeemable for cash or, at the Company's option, exchangeable for common shares on a one-for-one basis, and DownREIT OP units are redeemable for cash or, at the Company's option, exchangeable for OP units in its operating partnership on a one-for-one basis, subject to certain adjustments in each case. The holders of OP units are generally not entitled to elect redemption until one year after the issuance of the OP units. The holders of DownREIT OP units are generally not entitled to elect redemption until five years after the date of the contributor's initial contribution. The increase in OP Units outstanding from December 31, 2018 to December 31, 2019 was due to the issuance of 863,148 OP units related to the voluntary conversions of 913,680 subordinated performance units (as discussed further below), the issuance of 350,319 OP units in connection with the acquisition of self storage properties, 396,224 LTIP units which were converted into OP units and the issuance of 285,512 OP units in connection with the acquisition of an interest in a tenant reinsurance company and related cash flows, as discussed in Note 11, partially offset by the redemption of 581,001 OP units for common shares. The increase in DownREIT OP units outstanding from December 31, 2018 to December 31, 2019 was due to the issuance of 13,475 DownREIT OP units related to the conversion of 15,377 DownREIT subordinated performance units (as discussed further below). Subordinated Performance Units and DownREIT Subordinated Performance Units Subordinated performance units may also, under certain circumstances, be convertible into OP units which are exchangeable for common shares as described above, and DownREIT subordinated performance units may, under certain circumstances, be exchangeable for subordinated performance units on a one-for-one basis. Subordinated performance units are only convertible into OP units after a two Following such lock-out period, a holder of subordinated performance units in the Company's operating partnership may elect a voluntary conversion one time each year on or prior to December 1st to convert a pre-determined portion of such subordinated performance units into OP units in the Company's operating partnership, with such conversion effective January 1st of the following year, with each subordinated performance unit being converted into the number of OP units determined by dividing the average cash available for distribution, or CAD, per unit on the series of specific subordinated performance units over the one-year period prior to conversion by 110% of the CAD per unit on the OP units determined over the same period. CAD per unit on the series of specific subordinated performance units and OP units is determined by the Company based generally upon the application of the provisions of the LP Agreement applicable to the distributions of operating cash flow and capital transactions proceeds. The increase in subordinated performance units outstanding from December 31, 2018 to December 31, 2019 was due to the issuance of 1,178,400 subordinated performance units for co-investment by certain of the Company's PROs in connection with the acquisition of self storage properties partially offset by the voluntary conversion of 913,680 subordinated performance units into 863,148 OP units. The decrease in DownREIT subordinated performance units outstanding from December 31, 2018 to December 31, 2019 was due to the conversion of 15,377 DownREIT subordinated performance units into 13,475 DownREIT OP units. LTIP Units LTIP units are a special class of partnership interest in the Company's operating partnership that allow the holder to participate in the ordinary and liquidating distributions received by holders of the OP units (subject to the achievement of specified levels of profitability by the Company's operating partnership or the achievement of certain events). LTIP units may also, under certain circumstances, be convertible into OP units on a one-for-one basis, which are then exchangeable for common shares as described above. LTIP units do not have full parity with OP units with respect to liquidating distributions and may not receive ordinary distributions until such parity is reached pursuant to the terms of the LP Agreement. If such parity is reached under the LP Agreement, upon vesting, vested LTIP units may be converted into an equal number of OP units, and thereafter have all the rights of OP units, including redemption rights.

Credit Facility On July 29, 2019, the operating partnership, as borrower, the Company, and certain of the operating partnership's subsidiaries, as subsidiary guarantors, entered into a second amended and restated credit agreement with a syndicated group of lenders, which extended the maturities, enhanced the terms in line with the current market and increased the total borrowing capacity under the Company's unsecured credit facility by $255.0 million for a total of $1.275 billion (the "credit facility"). The credit facility consists of the following components: (i) a revolving line of credit (the "Revolver") which provides for a total borrowing commitment up to $500.0 million, under which the Company may borrow, repay and re-borrow amounts, (ii) a $125.0 million tranche A term loan facility (the "Term Loan A"), (iii) a $250.0 million tranche B term loan facility (the "Term Loan B"), (iv) a $225.0 million tranche C term loan facility (the "Term Loan C"), and (v) a $175.0 million tranche D term loan facility (the "Term Loan D").

The Revolver matures in January 2024; provided that the Company may elect to extend the maturity to July 2024 by paying an extension fee of 0.075% of the total borrowing commitment thereunder at the time of extension and meeting other customary conditions with respect to compliance. The Term Loan A matures in January 2023, the Term Loan B matures in July 2024, the Term Loan C matures in January 2025 and the Term Loan D matures in July 2026.

Compensatory Grants The Company grants two types of compensatory LTIP units, time-based LTIP unit awards that are subject to time-based vesting typically over a period of one Compensation expense related to compensatory LTIP units granted to members of the Company's senior management team, the Company's independent trustees, advisers, consultants and other personnel is included in general and administrative expense in the accompanying statements of operations. Total compensation cost recognized for the compensatory LTIP unit awards was $4.2 million, $3.6 million and $3.5 million for the years ended December 31, 2019, 2018 and 2017, respectively. At December 31, 2019, total unvested compensation cost not yet recognized was $3.7 million. The Company expects to recognize this compensation cost over a period of approximately 2.4 years. Time-based LTIP unit awards are granted with a fair value equal to the closing market price of the Company's common shares on the date of grant.

The simulation requires assumptions for expected volatility, risk-free rate of return, and dividend yield. The following table summarizes the assumptions used to value the performance-based LTIP unit awards granted during the years ended December 31, 2019, 2018 and 2017: 2019 2018 2017 Risk-free interest rate 2.51 % 2.04 % 1.58 % Dividend yield 4.54 % 4.11 % 4.35 % Expected volatility 25.40 % 24.44 % 29.96 % Acquisition Consideration Grants On December 31, 2013, the Company granted 1,683,560 LTIP units under the 2013 Plan to PROs as part of the consideration for their respective self storage property acquisitions and contributions. The following table presents the number of units vested for acquisition grants during the years ended December 31, 2019, 2018 and 2017: Total LTIP units Total unvested units, December 31, 2016 260,400 Units vested in 2017 related to properties contributed or sourced by PROs (36,400) Total unvested units, December 31, 2017 224,000 Units vested in 2018 related to properties contributed or sourced by PROs — Total unvested units, December 31, 2018 224,000 Units vested in 2019 related to properties contributed or sourced by PROs — Total unvested units, December 31, 2019 224,000 The aggregate fair value of purchase consideration recognized during the years ended December 31, 2017 was $0.9 million. As of December 31, 2019, the remaining unvested LTIP units will vest as additional self storage properties are contributed or sourced by the PROs. The fair value of such LTIP units will be recorded as additional acquisition consideration based on the fair value in the period such acquisitions are completed. Grants to Consultants During the years ended December 31, 2019, 2018 and 2017, the Company issued 5,714, 174 and 776 LTIP units, respectively, that were immediately vested to consultants that provided acquisition services. During the years ended December 31, 2019, 2018 and 2017, the self storage properties acquired were accounted for as asset acquisitions and accordingly, the acquisition costs related to the LTIP units granted to consultants were capitalized as part of the basis of the acquired properties. The aggregate fair value of the LTIP units was $0.2 million, less than $0.1 million and less than $0.1 million for the years ended December 31, 2019, 2018 and 2017, respectively. Restricted Common Shares Through December 31, 2019, an aggregate of 72,354 restricted common shares have been issued under the 2015 Plan. These restricted common shares vest over a weighted average period of approximately 3.0 years. Restricted common shares are granted with a fair value equal to the closing market price of the Company's common shares on the date of grant.

Total compensation cost recognized for restricted common shares during the years ended December 31, 2019, 2018 and 2017 was $0.3 million, $0.3 million and $0.2 million, respectively. At December 31, 2019, total unvested compensation cost not yet recognized was $0.4 million. The Company expects to recognize this compensation cost over a period of approximately 2.0 years. If the grantee has a termination of service for any reason during the vesting period, the unvested restricted common shares will be forfeited. Compensation expense related to restricted common shares is included in general and administrative expense in the accompanying statements of operations.

Earnings Per Share [Abstract]
EARNINGS PER SHARE	EARNINGS PER SHARE The following table sets forth the computation of basic and diluted earnings (loss) per common share for the years ended December 31, 2019, 2018 and 2017 (in thousands, except per share amounts): Year Ended December 31, 2019 2018 2017 Earnings (loss) per common share - basic and diluted Numerator Net income $ 66,013 $ 56,326 $ 45,998 Net income attributable to noncontrolling interests (62,030) (42,217) (43,037) Net income attributable to National Storage Affiliates Trust 3,983 14,109 2,961 Distributions to preferred shareholders (12,390) (10,350) (2,300) Distributed and undistributed earnings allocated to participating securities (35) (27) (28) Net (loss) income attributable to common shareholders - basic and diluted $ (8,442) $ 3,732 $ 633 Denominator Weighted average shares outstanding - basic and diluted 58,208 53,293 44,423 Earnings (loss) per share - basic and diluted $ (0.15) $ 0.07 $ 0.01 Dividends declared per common share $ 1.27 $ 1.16 $ 1.04 As discussed in Note 2, the Company allocates GAAP income (loss) utilizing the HLBV method, in which the Company allocates income or loss based on the change in each unitholders' claim on the net assets of its operating partnership at period end after adjusting for any distributions or contributions made during such period. Due to the stated liquidation priorities and because the HLBV method incorporates non-cash items such as depreciation expense, in any given period, income or loss may be allocated disproportionately to National Storage Affiliates Trust and noncontrolling interests, resulting in volatile fluctuations of basic and diluted earnings (loss) per share. Outstanding equity interests of the Company's operating partnership and DownREIT partnerships are considered potential common shares for purposes of calculating diluted earnings (loss) per share as the unitholders may, through the exercise of redemption rights, obtain common shares, subject to various restrictions. Basic earnings per share is calculated based on the weighted average number of common shares outstanding during the period. Diluted earnings per share is calculated by further adjusting for the dilutive impact using the treasury stock method for unvested LTIP units subject to a service condition outstanding during the period and the if-converted method for any convertible securities outstanding during the period. Generally, following certain lock-out periods, OP units in the Company's operating partnership are redeemable for cash or, at the Company's option, exchangeable for common shares on a one-for-one basis, subject to certain adjustments and DownREIT OP units are redeemable for cash or, at the Company's option, exchangeable for OP units in its operating partnership on a one-for-one basis, subject to certain adjustments in each case. LTIP units may also, under certain circumstances, be convertible into OP units on a one-for-one basis, which are then exchangeable for common shares as described above. Vested LTIP units and unvested LTIP units that vest based on a service condition are allocated income or loss in a similar manner as OP units. Unvested LTIP units subject to a service condition are evaluated for dilution using the treasury stock method. For the year ended December 31, 2019, 448,089 unvested LTIP units that vest based on a service condition are excluded from the calculation of diluted earnings (loss) per share as they are not dilutive to earnings (loss) per share. For the year ended December 31, 2019, 224,000 unvested LTIP units that vest upon the future acquisition of properties are excluded from the calculation of diluted earnings (loss) per share because the contingency for the units to vest has not been attained as of the end of the reported period. Subordinated performance units may also, under certain circumstances, be convertible into OP units which are exchangeable for common shares as described above, and DownREIT subordinated performance units may, under certain circumstances, be exchangeable for subordinated performance units on a one-for-one basis. Subordinated performance units are only convertible into OP units, after a two two two For the years ended December 31, 2019, 2018 and 2017, potential common shares totaling 54.2 million, 50.6 million and 50.6 million, respectively, related to OP units, DownREIT OP units, subordinated performance units, DownREIT subordinated performance units and vested LTIP units have been excluded from the calculation of diluted earnings (loss) per share as they are not dilutive to earnings (loss) per share. Participating securities, which consist of unvested restricted common shares, receive dividends equal to those received by common shares. The effect of participating securities for the periods presented above is calculated using the two-class method of allocating distributed and undistributed earnings.

Related Party Transactions [Abstract]
RELATED PARTY TRANSACTIONS	RELATED PARTY TRANSACTIONS Supervisory and Administrative Fees For the self storage properties that are managed by the PROs, the Company has entered into asset management agreements with the PROs to provide leasing, operating, supervisory and administrative services. The asset management agreements generally provide for fees ranging from 5% to 6% of gross revenue for the managed self storage properties. During the years ended December 31, 2019, 2018 and 2017, the Company incurred $20.0 million, $16.9 million and $14.4 million, respectively, for supervisory and administrative fees to the PROs. Such fees are included in general and administrative expenses in the accompanying statements of operations. Payroll Services For the self storage properties that are managed by the PROs, the employees responsible for operation of the self storage properties are generally employees of the PROs who charge the Company for the costs associated with the respective employees. For the years ended December 31, 2019, 2018 and 2017, the Company incurred $32.0 million, $29.5 million and $24.6 million, respectively, for payroll and related costs reimbursable to these PROs. Such costs are included in property operating expenses in the accompanying statements of operations. Due Diligence Costs During the years ended December 31, 2019, 2018 and 2017, the Company incurred $0.7 million, $0.4 million and $0.7 million, respectively, of expenses payable to certain PROs related to self storage property acquisitions sourced by the PROs. These expenses, which are based on the volume of transactions sourced by the PROs, are intended to reimburse the PROs for due diligence costs incurred in the sourcing and underwriting process. For the years ended December 31, 2019, 2018 and 2017 these due diligence costs are capitalized as part of the basis of the acquired self storage properties. Notes Receivable In connection with the acquisition of 16 self storage properties from PROs during the year ended December 31, 2014, the Company assumed certain mortgages that provided for interest at above-market rates. The sellers of the self storage properties agreed to reimburse the Company for the difference between the fair value and the contractual value of the assumed mortgages which amounted to $5.2 million. Due to the structure of the transaction, the amount owed to the Company was considered a receivable for the issuance of equity and was recorded as an offset against equity. During the years ended December 31, 2019 and 2018, the Company received above-market interest reimbursements from the sellers totaling $1.3 million and $1.2 million, respectively. In addition, in exchange for $1.3 million and $1.2 million of principal payment reimbursements received related to these assumed mortgages during the years ended December 31, 2019 and 2018, the Company issued 37,770 common shares and 44,502 OP units to the sellers during the year ended December 31, 2019 and 2018, respectively. Self Storage Property Acquisitions During the year ended December 31, 2019, the Company issued 11,100 subordinated performance units to an affiliate of Personal Mini (the Company's executive chairman and former chief executive officer, Arlen D. Nordhagen, has a noncontrolling minority ownership interest in this affiliate of Personal Mini), for $0.4 million of co-investment related to the acquisition of a self storage property from an unrelated third party. During the year ended December 31, 2019, the Company acquired one self storage property from the 2016 Joint Venture for $4.1 million. Acquisition of Interest in Reinsurance Company and Related Cash Flows On June 1, 2019, the Company, as acquiror, and Ground Up Development LLC ("Ground Up"), an affiliate of SecurCare and of the Company's executive chairman and former chief executive officer, Arlen D. Nordhagen, entered into a Contribution and Purchase Agreement (the "Ground Up Contribution Agreement") whereby the Company acquired Ground Up’s ownership interest (approximately 5.5%) in SBOA TI Reinsurance Ltd. (the "Reinsurance Company"), a Cayman Islands exempted company. The Reinsurance Company provides reinsurance for a self storage tenant insurance program issued by a licensed insurance company, whereby tenants of the Company's self storage facilities and tenants of other operators participating in the program can purchase insurance to cover damage or destruction to their personal property while stored at such facilities. The Company will now be entitled to receive its share of distributions of any profits generated by the Reinsurance Company, depending on actual losses incurred by the program. As part of the transaction, the Company also acquired the rights to the access fees previously earned by Ground Up associated with the tenant insurance-related arrangements. For the Company's properties managed by SecurCare, in addition to the tenant insurance revenues the Company received directly from the program insurer, the Company also receives these additional access fees. The consideration paid for the interest in the Reinsurance Company was $15.1 million, which consisted of $6.6 million of cash and 285,512 OP units totaling $8.5 million. Of the total consideration transferred, Arlen D. Nordhagen received $2.2 million of cash and 95,170 OP Units totaling approximately $2.8 million. The Ground Up Contribution Agreement contains customary representations, warranties, covenants and agreements of the Company and Ground Up. The Company allocated the total purchase price to the estimated fair value of the assets acquired, consisting of $0.5 million of equity interest in the Reinsurance Company and $14.6 million as an intangible related to the acquired access fees and rights to control the tenant insurance-related arrangements. These assets are reported in other assets, net in the Company's consolidated balance sheets. The intangible asset is amortized on a straight-line basis over 25 years, which approximates the weighted average remaining useful life of the SecurCare-managed properties, and is recorded in depreciation and amortization expense in the Company's consolidated statements of operations.

Leases [Abstract]
LEASES	LEASES The Company determines if a contractual arrangement is a lease at inception. As a lessee, the Company has non-cancelable lease agreements for real estate and its corporate office space that are classified as operating leases. The Company's operating leases are included in operating lease right-of-use ("ROU") assets and operating lease liabilities in its consolidated balance sheets. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the Company's operating leases do not provide an implicit rate, the Company used its incremental borrowing rate based on the information available at commencement date in determining the discount rate for the present value of the lease payments. To the extent that the lease agreements provide for fixed increases throughout the term of the lease, the Company recognizes lease expense on a straight-line basis over the expected lease terms. Real Estate Leasehold Interests The Company has eight properties that are subject to non-cancelable leasehold interest agreements with remaining lease terms ranging from 15 to 73 years, inclusive of extension options that the Company anticipates exercising. Rent expense under these leasehold interest agreements is included in property operating expenses in the accompanying consolidated statements of operations and amounted to $1.6 million, $1.6 million and $1.2 million for the years ended December 31, 2019, 2018 and 2017, respectively. Office Leases The Company has entered into non-cancelable lease agreements for its corporate office space with remaining lease terms ranging from three The weighted-average remaining lease term and the weighted-average discount rate for the Company's operating leases as of December 31, 2019 are as follows: December 31, 2019 Weighted-average remaining lease term Real estate leasehold interests 29 years Office leases 7 years Weighted-average remaining discount rate Real estate leasehold interests 4.9 % Office leases 4.1 % As of December 31, 2019, the future minimum lease payments under the Company's operating leases, for which the Company is a lessee, are as follows (in thousands): Year Ending December 31, Real Estate Leasehold Interests Office Leases Total 2020 $ 1,419 $ 286 $ 1,705 2021 1,444 387 1,831 2022 1,459 381 1,840 2023 1,464 346 1,810 2024 1,470 353 1,823 2025 through 2092 36,728 691 37,419 Total lease payments $ 43,984 $ 2,444 $ 46,428 Less imputed interest (21,440) (323) (21,763) Total $ 22,544 $ 2,121 $ 24,665 As of December 31, 2018, the future minimum lease payments under the Company's operating leases, for which the Company is a lessee, are as follows (in thousands): Year Ending December 31, Real Estate Leasehold Interests Office Leases Total 2019 $ 1,334 $ 345 $ 1,679 2020 1,379 398 1,777 2021 1,404 387 1,791 2022 1,419 381 1,800 2023 1,424 346 1,770 2024 through 2092 36,074 1,073 37,147 Total lease payments $ 43,034 $ 2,930 $ 45,964

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	12 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS Recurring Fair Value Measurements The Company sometimes limits its exposure to interest rate fluctuations by entering into interest rate swap agreements. The interest rate swap agreements moderate the Company's exposure to interest rate risk by effectively converting the interest on variable rate debt to a fixed rate. The Company measures its interest rate swap derivatives at fair value on a recurring basis. The effective portion of changes in the fair value of derivatives designated and that qualify as cash flow hedges are recorded in accumulated other comprehensive income (loss) and are subsequently reclassified into earnings in the period that the hedged transaction affects earnings. The ineffective portion of the change in fair value of the derivatives is recognized directly into earnings. Information regarding the Company's interest rate swaps measured at fair value, which are classified within Level 2 of the GAAP fair value hierarchy, is presented below (dollars in thousands): Interest Rate Swaps Designated as Cash Flow Hedges Fair value at December 31, 2017 $ 12,414 Gains on interest rate swaps reclassified into interest expense from accumulated other comprehensive income (1,817) Unrealized gains on interest rate swaps included in accumulated other comprehensive income 3,598 Fair value at December 31, 2018 $ 14,195 Gains on interest rate swaps reclassified into interest expense from accumulated other comprehensive income (3,337) Unrealized losses on interest rate swaps included in accumulated other comprehensive income (29,941) Fair value at December 31, 2019 $ (19,083) As of December 31, 2019 and 2018, the Company had outstanding interest rate swaps designated as cash flow hedges with aggregate notional amounts of $1,125.0 million and $795.0 million, respectively. As of December 31, 2019, the Company's swaps had a weighted average remaining term of 4.3 years. The fair value of these swaps are presented within other assets and accounts payable and accrued liabilities in the accompanying balance sheets, and the Company recognizes any changes in the fair value as an adjustment of accumulated other comprehensive income (loss) within equity to the extent of their effectiveness. If the forward rates at December 31, 2019 remain constant, the Company estimates that during the next 12 months, the Company would reclassify into earnings approximately $3.2 million of the unrealized losses included in accumulated other comprehensive income (loss). If market interest rates increase above the 1.90% weighted average fixed rate under these interest rate swaps the Company will benefit from net cash payments due to it from its counterparty to the interest rate swaps. There were no transfers between levels during the years ended December 31, 2019 and 2018. For financial assets and liabilities that utilize Level 2 inputs, the Company utilizes both direct and indirect observable price quotes, including LIBOR yield curves. The Company uses valuation techniques for Level 2 financial assets and liabilities which include LIBOR yield curves at the reporting date as well as assessing counterparty credit risk. Counterparties to these contracts are highly rated financial institutions. Although the Company has determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with the Company's derivatives utilize Level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default by the Company and the counterparties. As of December 31, 2019 and 2018, the Company determined that the effect of credit valuation adjustments on the overall valuation of its derivative positions are not significant to the overall valuation of its derivatives. Therefore, the Company has determined that its derivative valuations are appropriately classified in Level 2 of the fair value hierarchy. Fair Value Disclosures The carrying values of cash and cash equivalents, restricted cash, trade receivables, accounts payable and accrued liabilities and equity securities reflected in the balance sheets at December 31, 2019 and 2018, approximate fair value due to the short term nature of these financial assets and liabilities. The carrying value of variable rate debt financing reflected in the balance sheets at December 31, 2019 and 2018 approximates fair value as the changes in their associated interest rates reflect the current market and credit risk is similar to when the loans were originally obtained.

SUBSEQUENT EVENTS	SUBSEQUENT EVENTS Internalization and Acquisition of PRO On February 24, 2020, the Company entered into a definitive agreement with SecurCare, and, among others, Arlen Nordhagen, the Company's executive chairman and former chief executive officer, who owns approximately 53% of SecurCare's outstanding shares, to merge SecurCare into a wholly owned subsidiary of the Company. On the same day, the Company entered into a definitive agreement with DLAN Corporation ("DLAN") to merge DLAN into another wholly owned subsidiary of the Company. DLAN is an entity controlled by Mr. Nordhagen that was formed solely to hold OP units and DownREIT OP units, and it is owned by Mr. Nordhagen's spouse, Wendy Nordhagen, and David Lamb, who is a key person of another existing PRO of the Company. As a result of the SecurCare merger, SecurCare's property management platform and related intellectual property will be internalized by the Company, and the Company will no longer pay any supervisory and administrative fees or reimbursements to SecurCare. In addition, distributions on the series of subordinated performance units related to SecurCare's managed portfolio (the "Series SC subordinated performance units") will be discontinued. As part of the internalization, most of SecurCare's employees and other key persons will be offered employment by the Company and will continue managing SecurCare's portfolio of properties under the brand SecurCare as members of the Company's existing property management platform. Under the terms of the Company's facilities portfolio management agreement with SecurCare, in connection with a retirement event leading to the internalization of SecurCare's property management platform, SecurCare is entitled to receive OP units in exchange for its property management platform and related intellectual property based on a contractual formula. The Company has determined that SecurCare would be entitled to receive 384,020 OP units as part of the internalization transaction. The Company expects that the acquisition of SecurCare's property management platform and related intellectual property will be accounted for as a business combination, whereby the Company will allocate the total purchase price to the estimated fair value of tangible and intangible assets acquired, and liabilities assumed. Immediately prior to the completion of the mergers, giving effect to the OP units that SecurCare owns or would be entitled to receive as part of the internalization and the conversion of 2,015,808 of the Series SC subordinated performance units into 6,769,083 OP units in connection with a retirement event leading to the internalization of SecurCare's property management platform, SecurCare and DLAN will own, or have the right to receive, an aggregate of 8,187,052 OP units. While OP units are economically equivalent to and exchangeable for common shares on a one-to-one basis, in the SecurCare and DLAN mergers, the Company expects to issue 8,105,192 common shares to the owners of SecurCare and DLAN, which represents a 1% discount to the number OP units that each of SecurCare and DLAN will own or be entitled to receive as set forth above immediately prior to the mergers. Of the total number of common shares expected to be issued to the owners of SecurCare, approximately 4.1 million common shares are expected to be issued to Mr. Nordhagen. Although the Company currently expects to complete the transactions described above during the second quarter of 2020, they are subject to customary closing conditions, and there is no assurance that the transactions will be consummated at all or at the time or pursuant to the terms currently contemplated. Self Storage Property Acquisitions In January and February 2020, the Company acquired 34 self storage properties for approximately $205.8 million. Consideration for these acquisitions included approximately $200.6 million of net cash, the assumption of $0.9 million of other working capital liabilities and OP equity of approximately $4.3 million (consisting of the issuance of 73,329 OP Units, 28,894 LTIP units and 13,105 subordinated performance units). In connection with these acquisitions, the Company reimbursed the PROs for $0.2 million of due diligence costs related to the self storage properties sourced by the PROs. In February 2020, the 2016 Joint Venture acquired two self storage properties for approximately $12.1 million. The 2016 Joint Venture financed the acquisitions with capital contributions from the 2016 Joint Venture members, of which the Company contributed $3.0 million. Subordinated Performance Unit To OP Unit Conversions Subordinated performance units are convertible into OP units after a two properties to which such subordinated performance units relate (a "voluntary conversion") or (ii) at the Company's election upon a retirement event of a PRO that holds such subordinated performance units or upon certain qualifying terminations. Following such lock-out period, a holder of subordinated performance units in the Company's operating partnership may elect a voluntary conversion one time each year prior to December 1st to convert a pre-determined portion of such subordinated performance units into OP units in the Company's operating partnership, with such conversion effective January 1st of the following year with each subordinated performance unit being converted into the number of OP units determined by dividing the average cash available for distribution, or CAD, per unit on the series of specific subordinated performance units over the one During the year ended December 31, 2019, the Company received notices requesting the conversion of 332,738 subordinated performance units. Effective January 1, 2020, the Company issued 445,701 OP units in satisfaction of such conversion requests.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements are presented on the accrual basis of accounting in accordance with U.S. generally accepted accounting principles ("GAAP").
Principles of Consolidation and Noncontrolling Interests	Principles of Consolidation The Company's consolidated financial statements include the accounts of its operating partnership and its controlled subsidiaries. All significant intercompany balances and transactions have been eliminated in the consolidation of entities. When the Company obtains an economic interest in an entity, the Company evaluates the entity to determine if the entity is deemed a variable interest entity ("VIE"), and if the Company is deemed to be the primary beneficiary, in accordance with authoritative guidance issued on the consolidation of VIEs. When an entity is not deemed to be a VIE, the Company considers the provisions of additional guidance to determine whether the general partner controls a limited partnership or similar entity when the limited partners have certain rights. The Company consolidates all entities that are VIEs and of which the Company is deemed to be the primary beneficiary. The Company has determined that its operating partnership is a VIE. The sole significant asset of National Storage Affiliates Trust is its investment in its operating partnership, and consequently, substantially all of the Company's assets and liabilities represent those assets and liabilities of its operating partnership. As of December 31, 2019, the Company's operating partnership was the primary beneficiary of, and therefore consolidated, 21 DownREIT partnerships that are considered VIEs, which owned 34 self storage properties. The net book value of the real estate owned by these VIEs was $233.1 million and $240.4 million as of December 31, 2019 and December 31, 2018, respectively. For certain DownREIT partnerships which are subject to fixed rate mortgages payable, the carrying value of such fixed rate mortgages payable held by these VIEs was $136.4 million and $138.4 million as of December 31, 2019 and December 31, 2018, respectively. The creditors of the consolidated VIEs do not have recourse to the Company's general credit. Noncontrolling Interests All of the limited partner equity interests ("OP equity") in its operating partnership not held by the Company are reflected as noncontrolling interests. Noncontrolling interests also include ownership interests in DownREIT partnerships held by entities other than the Company's operating partnership. In the consolidated statements of operations, the Company allocates net income (loss) attributable to noncontrolling interests to arrive at net income (loss) attributable to National Storage Affiliates Trust. For transactions that result in changes to the Company's ownership interest in its operating partnership, the carrying amount of noncontrolling interests is adjusted to reflect such changes. The difference between the fair value of the consideration received or paid and the amount by which the noncontrolling interests is adjusted is reflected as an adjustment to additional paid-in capital on the consolidated balance sheets.
Self Storage Properties	Self Storage Properties Self storage properties are carried at historical cost less accumulated depreciation and any impairment losses. Major replacements and betterments, which improve or extend the life of an asset, are capitalized. Expenditures for ordinary repairs and maintenance are expensed as incurred and are included in property operating expenses. Estimated depreciable lives of self storage properties are determined by considering the age and other indicators about the condition of the assets at the respective dates of acquisition, resulting in a range of estimated useful lives for assets within each category. All self storage property assets are depreciated using the straight-line method. Buildings and improvements are depreciated over estimated useful lives primarily between seven three When a self storage property is acquired, the purchase price of the acquired self storage property is allocated to land, buildings and improvements, furniture and equipment, customer in-place leases, assumed real estate leasehold interests, and other assets acquired and liabilities assumed, based on the estimated fair value of each component. When a portfolio of self storage properties is acquired, the purchase price is allocated to the individual self storage properties based on the fair value determined using an income approach with appropriate risk-adjusted capitalization rates, which take into account the relative size, age and location of the individual self storage properties.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly-liquid investments purchased with original maturities of three months or less to be cash equivalents. From time to time, the Company maintains cash balances in financial institutions in excess of federally insured limits. The Company has never experienced a loss that resulted from exceeding federally insured limits.
Restricted Cash	Restricted Cash The Company's restricted cash consists of escrowed funds deposited with financial institutions for real estate taxes, insurance and other reserves for capital improvements in accordance with the Company's loan agreements.
Customer In-place Leases	Customer In-place Leases In allocating the purchase price for a self storage property acquisition, the Company determines whether the acquisition includes intangible assets. The Company allocates a portion of the purchase price to an intangible asset attributed to the value of customer in-place leases. This intangible asset is amortized to expense using the straight-line method over 12 months, the estimated average rental period for the leases. Substantially all of the leases in place at acquired properties are at market rates, as the leases are month-to-month contracts.
Impairment of Long-Lived Assets	Impairment of Long-Lived AssetsThe Company evaluates long-lived assets for impairment when events and circumstances indicate that there may be impairment. When events or changes in circumstances indicate that the Company's long-lived assets may not be recoverable, the carrying value of these long-lived assets is compared to the undiscounted future net operating cash flows, plus a terminal value attributable to the assets. If an asset's carrying value is not considered recoverable, an impairment loss is recorded to the extent the net carrying value of the asset exceeds the fair value.
Costs of Raising Capital	Costs of Raising CapitalCommissions, legal fees and other costs that are directly associated with equity offerings are capitalized as deferred offering costs, pending a determination of the success of the offering. Deferred offering costs related to successful offerings are charged to additional paid-in capital within equity in the period it is determined that the offering was successful.
Debt Issuance Costs	Debt issuance costs are amortized over the estimated life of the related debt using the straight-line method, which approximates the effective interest rate method. Amortization of debt issuance costs is included in interest expense in the accompanying statements of operations.
Rental Revenue	Rental revenueRental revenue consists of space rentals and related fees. Management has determined that all of the Company's leases are operating leases. Substantially all leases may be terminated on a month-to-month basis and rental income is recognized ratably over the lease term using the straight-line method. Rents received in advance are deferred and recognized on a straight-line basis over the related lease term associated with the prepayment. Promotional discounts and other incentives are recognized as a reduction to rental income over the applicable lease term.
Other Property-related Revenue and Management Fees and Other Revenue	Other property-related revenue Other property-related revenue primarily consists of ancillary revenues such as tenant insurance and/or tenant warranty protection-related access fees and sales of storage supplies which are recognized in the period earned. The Company and certain of the Company’s PROs have tenant insurance- and/or tenant warranty protection plan-related arrangements with insurance companies and the Company’s tenants. During the years ended December 31, 2019, 2018 and 2017, the Company recognized $9.1 million, $7.5 million and $6.0 million, respectively, of tenant insurance and tenant warranty protection plan revenues. The Company sells boxes, packing supplies, locks and other retail merchandise at its properties. During the years ended December 31, 2019, 2018 and 2017, the Company recognized retail sales of $1.7 million, $1.5 million and $1.3 million, respectively. Management fees and other revenue Management fees and other revenue consist of property management fees, platform fees, call center fees, acquisition fees, and a portion of tenant warranty protection or tenant insurance proceeds that the Company earns for managing and operating its unconsolidated real estate ventures. With respect to both the 2018 Joint Venture and the 2016 Joint Venture, the Company provides supervisory and administrative property management services, centralized call center services, and technology platform and revenue management services to the properties in the unconsolidated real estate ventures. The property management fees are equal to 6% of monthly gross revenues and net sales revenues from the assets of the unconsolidated real estate ventures, and the platform fees are equal to $1,250 per month per unconsolidated real estate venture property. With respect to the 2016 Joint Venture only, the call center fees are equal to 1% of each of monthly gross revenues and net sales revenues from the 2016 Joint Venture properties. During the years ended December 31, 2019, 2018 and 2017, the Company recognized property management fees, call center fees and platform fees of $12.8 million, $7.8 million and $4.8 million, respectively. For acquisition fees, the Company provides sourcing, underwriting and administration services to the unconsolidated real estate ventures. The 2016 Joint Venture paid the Company a $4.1 million acquisition fee equal to 0.65% of the gross capitalization (including debt and equity) of the original 66-property 2016 Joint Venture portfolio (the "Initial 2016 JV Portfolio") in 2016, at the time of the Initial 2016 JV Portfolio acquisition. The 2018 Joint Venture paid the Company a $4.0 million acquisition fee related to the initial acquisition of properties by the 2018 Joint Venture (the "Initial 2018 JV Portfolio") during the year ended December 31, 2018, at the time of the Initial 2018 JV Portfolio acquisition. These fees are refundable to the unconsolidated real estate ventures, on a prorated basis, if the Company is removed as the managing member during the initial four four The Company also earns acquisition fees for properties acquired by the unconsolidated real estate ventures subsequent to the Initial 2016 JV Portfolio and the Initial 2018 JV Portfolio. These fees are based on a percentage of the gross capitalization of the acquired assets determined by the members of the 2016 Joint Venture and the 2018 Joint Venture, and are generally earned when the unconsolidated real estate ventures obtain title and control of an acquired property. During the years ended December 31, 2019, 2018 and 2017, the Company recognized acquisition fees of $1.8 million, $1.6 million and $1.5 million, respectively. An affiliate of the Company facilitates tenant warranty protection or tenant insurance programs for tenants of the properties in the unconsolidated real estate ventures in exchange for 50% of all proceeds from such programs at each unconsolidated real estate venture property. During the years ended December 31, 2019, 2018 and 2017, the Company recognized $4.7 million, $2.4 million and $1.9 million, respectively, of revenue related to these activities.
Advertising Costs	Advertising CostsThe Company incurs advertising costs primarily attributable to internet, directory and other advertising. Advertising costs are included in property operating expenses in the accompanying statements of operations. These costs are expensed in the period in which the cost is incurred.
Acquisition Costs	Acquisition Costs The Company incurs title, legal and consulting fees, and other costs associated with the completion of acquisitions. During the year ended December 31, 2017, the Company adopted Accounting Standards Update ("ASU") 2017-01 and as a result, the Company's self storage property acquisitions during the years ended December 31, 2019 and 2018 were accounted for as asset acquisitions, and accordingly, acquisition costs directly related to the self storage property acquisitions were capitalized as part of the basis of the acquired properties. Indirect acquisition costs remain included in acquisition costs in the accompanying statements of operations in the period in which they were incurred. Prior to the Company's adoption of ASU 2017-01, direct and indirect costs were included in acquisition costs in the accompanying statements of operations in the period in which they were incurred.
Income Taxes	Income Taxes The Company has elected and believes it has qualified to be taxed as a REIT under sections 856 through 860 of the U.S. Internal Revenue Code (the "Code") commencing with the taxable year ended December 31, 2015. To qualify as a REIT, among other things, the Company is required to distribute at least 90% of its REIT taxable income to its shareholders and meet certain tests regarding the nature of its income and assets. As a REIT, the Company is not subject to federal income tax on the earnings distributed currently to its shareholders that it derives from its REIT qualifying activities. If the Company fails to qualify as a REIT in any taxable year, and is unable to avail itself of certain provisions set forth in the Code, all of the Company's taxable income would be subject to federal and state income taxes at regular corporate rates. The Company will not be required to make distributions with respect to income derived from the activities conducted through subsidiaries that the Company elects to treat as taxable REIT subsidiaries ("TRS") for federal income tax purposes. Certain activities that the Company undertakes must be conducted by a TRS, such as performing non-customary services for its customers, facilitating sales by PROs of tenant insurance and holding assets that the Company is not permitted to hold directly. A TRS is subject to federal and state income taxes. On June 25, 2014, the Company formed NSA TRS, LLC ("NSA TRS"), a Delaware limited liability company. The Company has elected to treat NSA TRS as a TRS, and consequently, NSA TRS is subject to U.S. federal and state corporate income taxes. Deferred tax assets and liabilities are recognized to the extent of any differences between the financial reporting and tax bases of assets and liabilities. No material deferred tax assets and liabilities were recorded as of December 31, 2019 and 2018. The Company did not have any unrecognized tax benefits related to uncertain tax positions as of December 31, 2019 and 2018. Future amounts of accrued interest and penalties, if any, related to uncertain tax positions will be recorded as a component of income tax expense. The Company does not expect that the amount of unrecognized tax benefits will change significantly in the next 12 months.
Earnings per Share	Earnings per Share Basic earnings per share is calculated based on the weighted average number of the Company's common shares of beneficial interest, $0.01 par value per share ("common shares"), outstanding during the period. Diluted earnings per share is calculated by further adjusting for the dilutive impact using the treasury stock method for any share options and unvested share equivalents outstanding during the period and the if-converted method for any convertible securities outstanding during the period. As more fully described below under " –Allocation of Net Income (Loss)" , the Company allocates GAAP income (loss) utilizing the hypothetical liquidation at book value ("HLBV") method, which could result in net income (or net loss) attributable to National Storage Affiliates Trust during a period when the Company reports consolidated net loss (or net income), or net income (or net loss) attributable to National Storage Affiliates Trust in excess of the Company's consolidated net income (or net loss). The computations of basic and diluted earnings (loss) per share may be materially affected by these disproportionate income (loss) allocations, resulting in volatile fluctuations of basic and diluted earnings (loss) per share.
Equity-Based Awards	Equity-Based Awards The measurement and recognition of compensation cost for all equity-based awards granted to officers, employees and consultants is based on estimated fair values. Compensation cost is recognized on a straight-line basis over the requisite service periods of each award with non-graded vesting. For awards granted which contain a graded vesting schedule and the only condition for vesting is a service condition, compensation cost is recognized as an expense on a straight-line basis over the requisite service period as if the award was, in substance, a single award. For awards granted for which vesting is subject to a performance condition, compensation cost is recognized over the requisite service period if and when the Company concludes it is probable that the performance condition will be achieved. The estimated fair value of all equity-based awards issued to PROs and their affiliates in connection with self storage property acquisitions is included in the cost of the respective acquisitions. The estimated fair value of such
Derivative Financial Instruments	Derivative Financial Instruments The Company carries all derivative financial instruments on the balance sheet at fair value. Fair value of derivatives is determined by reference to observable prices that are based on inputs not quoted on active markets, but corroborated by market data. The accounting for changes in the fair value of a derivative instrument depends on whether the derivative has been designated and qualifies as part of a hedging relationship. The Company's use of derivative instruments has been limited to interest rate swap and cap agreements. The fair values of derivative instruments are included in other assets and accounts payable and accrued liabilities in the accompanying balance sheets. For derivative instruments not designated as cash flow hedges, the unrealized gains and losses are included in interest expense in the accompanying statements of operations. For derivatives designated as cash flow hedges, the effective portion of the changes in the fair value of the derivatives is initially reported in accumulated other comprehensive income (loss) in the Company's balance sheets and subsequently reclassified into earnings when the hedged transaction affects earnings. The valuation of interest rate swap and cap agreements is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves. The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts are based on an expectation of future interest rates (forward curves) derived from observable market interest rate forward curves. The Company may enter into derivative contracts that are intended to economically hedge certain of its risk, even though hedge accounting does not apply or the Company elects not to apply hedge accounting.
Fair Value Measurements	Fair Value Measurements When measuring fair value of financial instruments that are required to be recorded or disclosed at fair value, the Company uses a three-tier measurement hierarchy which prioritizes the inputs used to calculate fair value. These tiers include Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.
Investments in Unconsolidated Real Estate Venture	Investments in Unconsolidated Real Estate Ventures The Company’s investments in its unconsolidated real estate ventures are recorded under the equity method of accounting in the accompanying consolidated financial statements. Under the equity method, the Company’s investments in unconsolidated real estate ventures are stated at cost and adjusted for the Company’s share of net earnings or losses and reduced by distributions. Equity in earnings (losses) is recognized based on the Company’s ownership interest in the earnings (losses) of the unconsolidated real estate ventures. The Company follows the "nature of the distribution approach" for classification of distributions from its unconsolidated real estate ventures in its consolidated statements of cash flows. Under this approach, distributions are reported on the basis of the nature of the activity or activities that generated the distributions as either a return on investment, which are classified as operating cash flows, or a return of investment (e.g., proceeds from the unconsolidated real estate ventures' sale of assets) which are reported as investing cash flows.
Segment Reporting	Segment ReportingThe Company manages its business as one reportable segment consisting of investments in self storage properties located in the United States. Although the Company operates in several markets, these operations have been aggregated into one reportable segment based on the similar economic characteristics among all markets.
Allocation of Net Income (Loss)	Allocation of Net Income (Loss) The distribution rights and priorities set forth in the operating partnership's LP Agreement differ from what is reflected by the underlying percentage ownership interests of the operating partnership's unitholders. Accordingly, the Company allocates GAAP income (loss) utilizing the HLBV method, in which the Company allocates income or loss based on the change in each unitholders’ claim on the net assets of its operating partnership at period end after adjusting for any distributions or contributions made during such period. The HLBV method is commonly applied to equity investments where cash distribution percentages vary at different points in time and are not directly linked to an equity holder’s ownership percentage. The HLBV method is a balance sheet-focused approach to income (loss) allocation. A calculation is prepared at each balance sheet date to determine the amount that unitholders would receive if the operating partnership were to liquidate all of its assets (at GAAP net book value) and distribute the resulting proceeds to its creditors and unitholders based on the contractually defined liquidation priorities. The difference between the calculated liquidation distribution amounts at the beginning and the end of the reporting period, after adjusting for capital contributions and distributions, is used to derive each unitholder's share of the income (loss) for the period. Due to the stated liquidation priorities and because the HLBV method incorporates non-cash items such as depreciation expense, in any given period, income or loss may be allocated disproportionately to unitholders as compared to their respective ownership percentage in the operating partnership, and net income (loss) attributable to National Storage Affiliates Trust could be more or less net income than actual cash distributions received and more or less income or loss than what may be received in the event of an actual liquidation. Additionally, the HLBV method could result in net income (or net loss) attributable to National Storage Affiliates Trust during a period when the Company reports consolidated net loss (or net income), or net income (or net loss) attributable to National Storage Affiliates Trust in excess of the Company's consolidated net income (or net loss). The computations of basic and diluted earnings (loss) per share may be materially affected by these disproportionate income (loss) allocations, resulting in volatile fluctuations of basic and diluted earnings (loss) per share.
Other Comprehensive Income (Loss)	Other Comprehensive Income (Loss)The Company has cash flow hedge derivative instruments that are measured at fair value with unrealized gains or losses recognized in other comprehensive income (loss) with a corresponding adjustment to accumulated other comprehensive income (loss) within equity, as discussed further in Note 14. Under the HLBV method of allocating income (loss) discussed above, a calculation is prepared at each balance sheet date by applying the HLBV method including, and excluding, the assets and liabilities resulting from the Company's cash flow hedge derivative instruments to determine comprehensive income (loss) attributable to National Storage Affiliates Trust. As a result of the distribution rights and priorities set forth in the operating partnership's LP Agreement, in any given period, other comprehensive income (loss) may be allocated disproportionately to unitholders as compared to their respective ownership percentage in the operating partnership and as compared to their respective allocation of net income (loss).
Gain on Sale of Self Storage Properties	Gain on sale of self storage propertiesThe Company recognizes gains from disposition of facilities only upon closing in accordance with the guidance on sales of nonfinancial assets. Profit on real estate sold is recognized upon closing when all, or substantially all, of the promised consideration has been received and is nonrefundable and the Company has transferred control of the facilities to the purchaser.
Goodwill	GoodwillGoodwill represents the costs of business acquisitions in excess of the fair value of identifiable net assets acquired. The Company evaluates goodwill for potential impairment annually, or whenever impairment indicators are present.
Use of Estimates	Use of EstimatesThe preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In February 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-02, Leases, which amends the existing guidance for accounting for leases, including requiring lessors to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases and lessees to recognize most leases on-balance sheet as lease liabilities with corresponding right-of-use assets. In July 2018, the FASB issued ASU 2018-11, Leases - Targeted Improvements, which allows entities the option to apply the new standard at adoption date with a cumulative-effect adjustment in the period of adoption. The Company adopted ASU 2016-02 and ASU 2018-11 effective January 1, 2019 and applied it to leases that were in place on the effective date. The Company elected the practical expedients which permit the Company to combine lease and nonlease components and to not reassess (i) whether any expired or existing contracts are or contain leases, (ii) the lease classification for any expired or existing leases, and (iii) any initial direct costs for any existing leases as of the effective date. Results for reporting periods beginning January 1, 2019 are presented under ASU 2016-02 and ASU 2018-11. As a result, beginning on January 1, 2019, activity related to uncollectible accounts are recognized as a current-period adjustment within revenue. For periods prior to January 1, 2019, such amounts were previously included in operating expenses. The adoption of the lease standard did not result in a cumulative catch-up adjustment to opening equity. See Note 13 for additional detail about the Company's non-cancelable leasehold interest agreements where the Company is a lessee.
