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 499 self storage properties in 26 states and Puerto Rico with approximately 30.4 million rentable square feet (unaudited) in approximately 242,000 storage units as of December 31, 2018 . 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") and an affiliate of Shader Brothers Corporation d/b/a Personal Mini Storage ("Personal Mini"). In October 2018, the Company entered into definitive agreements with affiliates of Southern Self Storage, LLC d/b/a Southern Self Storage of Palm Beach Gardens, Florida, to add Southern Self Storage ("Southern") as the Company's ninth PRO. In January 2019, the Company completed the initial contribution transaction with Southern. As discussed in Note 15, in February 2019, the Company entered into definitive agreements with affiliates of Investment Real Estate Management, LLC d/b/a Moove In Self Storage of York, Pennsylvania to add Moove In Self Storage ("Moove In") as the Company's tenth PRO. As of December 31, 2018 , the Company also managed through its property management platform an additional portfolio of 176 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 22 states. The Company owns a 25% equity interest in each of its unconsolidated real estate ventures. As of December 31, 2018 , in total, the Company operated and held ownership interests in 675 self storage properties located across 34 states and Puerto Rico with approximately 43.0 million rentable square feet in approximately 345,000 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, 2018 , 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 $240.4 million and $248.0 million as of December 31, 2018 and December 31, 2017 , 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 $138.4 million and $140.3 million as of December 31, 2018 and December 31, 2017 , 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 and 40 years ; furniture and equipment are depreciated over estimated useful lives primarily between three and 10 years . 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, 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 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, 2018 , 2017 and 2016 , the Company recognized $7.5 million , $6.0 million and $4.2 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, 2018 , 2017 and 2016 , the Company recognized retail sales of $1.5 million , $1.3 million and $1.0 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, 2018 , 2017 and 2016 , the Company recognized property management fees, call center fees and platform fees of $7.8 million , $4.8 million and $1.1 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 year life of the unconsolidated real estate ventures and as such, the Company's performance obligation for these acquisition fees are satisfied over a four year period. As of December 31, 2018 and 2017 , the Company had deferred revenue related to the acquisition fees of $4.6 million and $2.8 million , respectively. 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, 2018 , 2017 and 2016 , the Company recognized acquisition fees of $1.6 million , $1.5 million and $0.3 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, 2018 , 2017 and 2016 , the Company recognized $2.4 million , $1.9 million and $0.5 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 $4.1 million , $3.7 million and $3.1 million for the years ended December 31, 2018 , 2017 and 2016 , 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, 2018 and 2017 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 Through December 31, 2014, the Company did not have a profit and loss sharing interest in its operating partnership and did not have any other operations that were subject to taxation. Accordingly, the Company did not generate a federal income tax benefit or expense for the period from its inception through December 31, 2014. 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, 2018 and 2017 . The Company did not have any unrecognized tax benefits related to uncertain tax positions as of December 31, 2018 and 2017 . 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 2015 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. Reclassifications Certain amounts in the consolidated financial statements and related notes have been reclassified to conform to the current year presentation. Such reclassifications do not impact the Company's previously reported financial position or 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 unitholders. Accordingly, the Company allocates GAAP income (loss) utilizing the hypothetical liquidation at book value ("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 13. 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). Assets Held For Sale The Company classifies properties as held for sale when certain criteria are met. At such time, the properties, including significant assets and liabilities that are expected to be transferred as part of a sale transaction, are presented separately on the consolidated balance sheet at the lower of carrying value or estimated fair value less costs to sell and depreciation is no longer recognized. As of December 31, 2017 , the Company had one self storage property classified as held for sale. The results of operations for the self storage properties classified as held for sale are reflected within income from operations in the Company's consolidated statements of operations. 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, 2018 and 2017 . 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 May 2014, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The Company adopted ASU 2014-09 effective January 1, 2018, and concluded that its adoption of ASU 2014-09 had no material effect on its consolidated financial statements as most of the Company's revenue is derived from lease contracts, which are excluded from the scope of the new guidance. For the Company’s other property-related revenue and management fees and other revenue subject to the new guidance, the Company performed an evaluation which included identifying its performance obligations and when such performance obligations are satisfied. Based on this evaluation, the Company determined that there was no material change in the timing or pattern of recognition of revenue for these activities as compared to the application of previous revenue recognition guidance. In February 2016, the 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. ASU 2016-02 initially required a modified retrospective approach, with entities applying the new guidance at the beginning of the earliest period presented in the financial statements in which they first apply the new standard, with certain elective transition relief. 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. The Company elected the package of practical expedients which permits the Company 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. As a lessor, the Company's recognition of rental revenue remained consistent with previous guidance, and the adoption of the lease standard did not change the Company's consolidated statements of operations and did not result in a cumulative catch-up adjustment to opening equity. Adoption of the lease standard will have a material impact on the Company's consolidated balance sheets for its non-cancelable leasehold interest agreements in which it is the lessee. As a lessee, the Company expects to record lease liabilities of approximately $24 million with corresponding right-of-use assets of approximately $23 million. See Note 12 for additional detail about the Company's non-cancelable leasehold interest agreements.

On December 16, 2016, the Company closed a follow-on offering of 5,175,000 of its common shares, which included 675,000 common shares sold upon the exercise in full by the underwriters of their option to purchase additional common shares, at an offering price of $20.48 per share. The Company received aggregate net proceeds from the offering of approximately $105.5 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 dividend 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, 2018 and 2017 , units reflecting noncontrolling interests consisted of the following: December 31, 2018 2017 Series A-1 preferred units 343,719 — OP units 28,874,103 26,719,607 Subordinated performance units 10,749,475 11,604,738 LTIP units 931,671 771,396 DownREIT units DownREIT OP units 1,834,786 1,834,786 DownREIT subordinated performance units 4,386,999 4,386,999 Total 47,120,753 45,317,526 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. The increase in Series A-1 preferred units outstanding from December 31, 2017 to December 31, 2018 was due to the issuance of Series A-1 preferred units in connection with the acquisition of self storage properties. 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, 2017 to December 31, 2018 was due to the issuance of 2,024,170 OP units related to the voluntary conversions of 997,074 subordinated performance units (as discussed further below), the issuance of 584,004 OP units in connection with the acquisition of self storage properties and 9,100 LTIP units which were converted into OP units, partially offset by the redemption of 462,778 OP units for common shares. 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 year lock-out period and then generally (i) at the holder’s election only upon the achievement of certain performance thresholds relating to the properties to which such subordinated performance units relate 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. The holders of DownREIT subordinated performance units are generally not entitled to elect redemption until at least five years after the date of the contributor's initial contribution. The decrease in subordinated performance units outstanding from December 31, 2017 to December 31, 2018 was due to the voluntary conversion of 997,074 subordinated performance units into 2,024,170 OP units partially offset by the issuance of 141,811 subordinated performance units for co-investment by certain of the Company's PROs in connection with the acquisition of self storage properties. 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. See Note 9 for additional information about the Company's LTIP Units. The increase in LTIP units outstanding from December 31, 2017 to December 31, 2018 was due to the issuance of compensatory LTIP units to employees, trustees and consultants net of forfeitures partially offset by the conversion of 9,100 LTIP units into OP units.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
EQUITY-BASED AWARDS	EQUITY-BASED AWARDS The Company grants awards in the form of LTIP units and restricted common shares to provide equity based incentive compensation to members of its senior management team, independent trustees, advisers, consultants, other personnel, and as consideration for self storage property acquisitions. LTIP units were first granted under the 2013 Long-Term Incentive Plan (the "2013 Plan"), which authorized up to 2.5 million LTIP units for issuance. In connection with the Company's initial public offering, the Company terminated the 2013 Plan but the awards granted thereunder remained outstanding after its termination. Restricted common shares were first granted under the 2015 National Storage Affiliates Trust Equity Incentive Plan (the "2015 Plan"), which authorizes the Company's compensation, nominating, and corporate governance committee to grant share options, restricted common shares, phantom shares, dividend equivalent rights, LTIP units and other restricted limited partnership units issued by its operating partnership and other equity-based awards up to an aggregate of 5% of the common shares issued and outstanding from time to time on a fully diluted basis (assuming, if applicable, the exercise of all outstanding options and the conversion of all warrants and convertible securities, including OP units and LTIP units, into common shares). As of December 31, 2018 , the Company did not have outstanding under its equity compensation plan, any options, warrants or rights to purchase the Company's common shares. LTIP Units Through December 31, 2018 , an aggregate of 2,474,710 LTIP units have been issued under the 2013 Plan, 565,672 LTIP units have been issued under the 2015 Plan, and 313,759 LTIP units have been issued under the LP Agreement. Some of the granted LTIP units vested immediately or upon completion of the Company's initial public offering. Others vest upon the contribution of self storage properties or along a schedule at certain times through May 15, 2022. 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 to three years from the grant date, so long as such person remains an employee or trustee, and performance-based LTIP unit awards, which are designed to align the interests of the Company's executive officers with those of the Company's shareholders in a pay-for-performance structure. The performance-based LTIP unit awards vest contingent upon the achievement of performance criteria measured over a period of three years from the grant date, which is based on the Company's total shareholder return ("TSR") relative to the TSR of the companies in the Morgan Stanley Capital International US REIT Index and the Company's TSR relative to the TSR of its peers in the self storage industry. The value of the performance-based LTIP unit awards take into consideration the probability that the awards will ultimately vest; therefore previously recorded compensation expense is not adjusted in the event that the performance criteria is not achieved. 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 $3.6 million , $3.5 million and $2.5 million for the years ended December 31, 2018 , 2017 and 2016 , respectively. At December 31, 2018 , total unvested compensation cost not yet recognized was $3.7 million . The Company expects to recognize this compensation cost over a period of approximately 3.4 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 following table summarizes activity for the time-based LTIP unit awards for the years ended December 31, 2018 , 2017 and 2016 : Time-Based LTIP Unit Awards 2018 2017 2016 Number of LTIP units Weighted Average Grant-Date Fair Value Number of LTIP units Weighted Average Grant-Date Fair Value Number of LTIP units Weighted Average Grant-Date Fair Value Outstanding unvested at beginning of year 227,766 $ 20.37 294,529 $ 14.74 236,265 $ 10.41 Granted 100,176 27.08 128,051 22.89 177,546 17.59 Vested (104,130 ) 20.18 (194,814 ) 13.43 (119,282 ) 10.41 Unvested at end of year 223,812 $ 23.54 227,766 $ 20.37 294,529 $ 14.74 The aggregate fair value of the time-based LTIP unit awards that vested during the years ended December 31, 2018 , 2017 and 2016 was $2.1 million , $2.6 million and $1.2 million , respectively. The following table summarizes activity for the performance-based LTIP unit awards granted during the year ended December 31, 2018 and 2017 , including the minimum, target and maximum number of LTIP units that may be earned upon the achievement of the performance criteria measured over the period of three years from the grant date.

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, 2018 and 2017 : 2018 2017 Risk-free interest rate 2.04 % 1.58 % Dividend yield 4.11 % 4.35 % Expected volatility 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 and forfeited for acquisition grants during the years ended December 31, 2018 , 2017 and 2016 : Total LTIP units Total unvested units, December 31, 2015 423,800 Units vested in 2016 related to properties contributed or sourced by PROs (45,100 ) Units forfeited (118,300 ) 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 The aggregate fair value of purchase consideration recognized during the years ended December 31, 2017 and 2016 was $0.9 million and $0.8 million , respectively. As of December 31, 2018 , 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. LP Agreement Grants to Consultants Pursuant to the LP Agreement, during the years ended December 31, 2018 , 2017 and 2016 , the Company issued 174 , 776 and 2,758 LTIP units, respectively, that were immediately vested to consultants that provided acquisition services. During the year s ended December 31, 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. Prior to January 1, 2017, the Company's self storage property acquisitions were accounted for as business combinations and accordingly, the acquisition costs related to the LTIP units granted to consultants during the year ended December 31, 2016 are included in acquisition costs in the accompanying statements of operations. The aggregate fair value of the LTIP units was less than $0.1 million , less than $0.1 million and $0.1 million for the years ended December 31, 2018 , 2017 and 2016 , respectively. Restricted Common Shares Through December 31, 2018 , an aggregate of 54,136 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. The following table summarizes activity for restricted common shares for the years ended December 31, 2018 , 2017 and 2016 : Year Ended December 31, 2018 2017 2016 Number of Restricted Common Shares Weighted Average Grant-Date Fair Value Number of Restricted Common Shares Weighted Average Grant-Date Fair Value Number of Restricted Common Shares Weighted Average Grant-Date Fair Value Outstanding at beginning of year 21,585 $ 22.43 13,590 $ 12.40 11,000 $ 12.40 Granted 12,311 27.26 16,525 24.04 8,090 17.19 Vested (8,041 ) 21.88 (8,530 ) 14.11 (5,500 ) 12.40 Forfeited (3,266 ) 25.35 — — — — Unvested at end of year 22,589 $ 24.83 21,585 $ 22.43 13,590 $ 12.40 The aggregate fair value of restricted common shares that vested during the years ended December 31, 2018 , 2017 and 2016 was $0.2 million , $0.1 million and $0.1 million respectively. Total compensation cost recognized for restricted common shares during the years ended December 31, 2018 , 2017 and 2016 was $0.3 million , $0.2 million and $0.1 million , respectively. At December 31, 2018 , total unvested compensation cost not yet recognized was $0.3 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, 2018 , 2017 and 2016 (in thousands, except per share amounts): Year Ended December 31, 2018 2017 2016 Earnings (loss) per common share - basic and diluted Numerator Net income $ 56,326 $ 45,998 $ 24,866 Net income attributable to noncontrolling interests (42,217 ) (43,037 ) (6,901 ) Net income attributable to National Storage Affiliates Trust 14,109 2,961 17,965 Distributions to preferred shareholders (10,350 ) (2,300 ) — Distributed and undistributed earnings allocated to participating securities (27 ) (28 ) (18 ) Net income attributable to common shareholders - basic 3,732 633 17,947 Effect of assumed conversion of dilutive securities — — 6,783 Net income attributable to common shareholders - diluted $ 3,732 $ 633 $ 24,730 Denominator Weighted average shares outstanding - basic 53,293 44,423 29,887 Effect of dilutive securities: Weighted average OP units outstanding — — 24,262 Weighted average DownREIT OP unit equivalents outstanding — — 1,835 Weighted average LTIP units outstanding — — 1,846 Weighted average subordinated performance units and DownREIT subordinated performance unit equivalents — — 20,917 Weighted average shares outstanding - diluted 53,293 44,423 78,747 Earnings (loss) per share - basic $ 0.07 $ 0.01 $ 0.60 Earnings (loss) per share - diluted $ 0.07 $ 0.01 $ 0.31 Dividends declared per common share $ 1.16 $ 1.04 $ 0.88 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, 2018 , 383,712 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, 2018 , 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 periods. 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 year lock-out period and then generally (i) at the holder’s election only upon the achievement of certain performance thresholds relating to the properties to which such subordinated performance units relate 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. Although subordinated performance units may only be convertible after a two year lock-out period, the Company assumes a hypothetical conversion of each subordinated performance unit (including each DownREIT subordinated performance unit) into OP units (with subsequently assumed redemption into common shares) for the purposes of calculating diluted weighted average common shares. This hypothetical conversion is calculated using historical financial information, and as a result, is not necessarily indicative of the results of operations, cash flows or financial position of the Company upon expiration of the two -year lock out period on conversions. For the years ended December 31, 2018 and 2017, potential common shares totaling 50.6 million and 50.6 million , respectively, related to OP units, DownREIT OP units, subordinated performance units and DownREIT subordinated performance 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 year s ended December 31, 2018 , 2017 and 2016 , the Company incurred $16.9 million , $14.4 million and $11.0 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 year s ended December 31, 2018 , 2017 and 2016 , the Company incurred $29.5 million , $24.6 million and $19.4 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 year s ended December 31, 2018 , 2017 and 2016 , the Company incurred $0.4 million , $0.7 million and $1.1 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, 2018 and 2017 these due diligence costs are capitalized as part of the basis of the acquired self storage properties and for the year ended December 31, 2016 , these due diligence costs are included in acquisition costs in the accompanying statements of operations. 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 year s ended December 31, 2018 and 2017 , the Company received above-market interest reimbursements from the sellers totaling $1.2 million and $1.3 million , respectively. In addition, in exchange for $1.2 million and $1.3 million of principal payment reimbursements received related to these assumed mortgages during the year s ended December 31, 2018 and 2017 , the Company issued 44,502 and 47,339 OP units to the sellers during the year ended December 31, 2018 and 2017 . Self Storage Property Acquisitions During the year ended December 31, 2018 , the Company issued 11,490 subordinated performance units to an affiliate of Personal Mini (the Company's chairman and chief executive officer, Arlen D. Nordhagen, has a noncontrolling minority ownership interest in this affiliate of Personal Mini), for $0.3 million of co-investment related to the acquisition of a self storage property from an unrelated third party. During the year ended December 31, 2018 , the Company issued 19,047 OP units and 5,824 subordinated performance units as partial consideration for the acquisition of self storage properties to an affiliate of Northwest and an affiliate of Kevin Howard, a member of the Company's board of trustees.

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, 2016 $ 8,159 Cash flow hedge ineffectiveness 12 Losses on interest rate swaps reclassified into interest expense from accumulated other comprehensive income 2,308 Unrealized gains included in accumulated other comprehensive income 1,935 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 included in accumulated other comprehensive income 3,598 Fair value at December 31, 2018 $ 14,195 As of December 31, 2018 and 2017 , the Company had outstanding interest rate swaps designated as cash flow hedges with aggregate notional amounts of $795.0 million and $595.0 million , respectively. As of December 31, 2018 , the Company's swaps had a weighted average remaining term of 4.5 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, 2018 remain constant, the Company estimates that during the next 12 months , the Company would reclassify into earnings approximately $5.4 million of the unrealized gains included in accumulated other comprehensive income (loss). If market interest rates increase above the 1.87% 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 year s ended December 31, 2018 and 2017 . 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, 2018 and 2017 , 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, and accounts payable and accrued liabilities reflected in the balance sheets at December 31, 2018 and 2017 , 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, 2018 and 2017 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. The fair values of fixed rate mortgages were estimated using the discounted estimated future cash payments to be made on such debt; the discount rates used approximated current market rates for loans, or groups of loans, with similar maturities and credit quality (categorized within Level 2 of the fair value hierarchy). The combined principal balance of the Company's fixed rate mortgages payable was approximately $268.1 million as of December 31, 2018 with a fair value of approximately $276.5 million . In determining the fair value, the Company estimated a weighted average market interest rate of approximately 4.17% , compared to the weighted average contractual interest rate of 4.85% . The combined principal balance of the Company's fixed rate mortgages was approximately $271.5 million as of December 31, 2017 with a fair value of approximately $282.6 million . In determining the fair value as of December 31, 2017 , the Company estimated a weighted average market interest rate of approximately 4.04% , compared to the weighted average contractual interest rate of 4.87% .

Subsequent Events [Abstract]
SUBSEQUENT EVENTS	SUBSEQUENT EVENTS Self Storage Property Acquisitions In January and February 2019, the Company acquired 23 self storage properties for approximately $147.0 million . Consideration for these acquisitions included approximately $122.9 million of net cash, the assumption of $0.4 million of other working capital liabilities and OP equity of approximately $23.7 million (consisting of the issuance of 58,942 OP Units, 158,199 Series A-1 preferred units and 692,075 subordinated performance units). In connection with these acquisitions, the Company reimbursed the PROs for $0.1 million of due diligence costs related to the self storage properties sourced by the PROs. New PRO In February 2019, the Company entered into definitive agreements with affiliates of Investment Real Estate Management, LLC d/b/a Moove In Self Storage of York, Pennsylvania to add Moove In Self Storage ("Moove In") as the Company's ten th PRO. Moove In currently owns 19 self storage properties in Pennsylvania, Maryland, New Jersey, and New York. Upon closing, Moove In intends to contribute six self storage properties to NSA as part of the initial contribution transaction, and its remaining properties will be added to the Company's captive pipeline. The Company expects the initial contribution transaction and related closing documentation, including the entry into a facilities portfolio management agreement, to close during the first quarter of 2019, subject to customary closing conditions. Subordinated Performance Unit To OP Unit Conversions Subordinated performance units are convertible into OP units after a two year lock-out period and then generally (i) at the holder’s election only upon the achievement of certain performance thresholds relating to the 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 -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 operating partnership agreement applicable to the distributions of operating cash flow and capital transactions proceeds. During the year ended December 31, 2018 , the Company received notices requesting the conversion of 929,057 subordinated performance units (including 15,377 subordinated performance units in the Company's DownREIT partnerships). Effective January 1, 2019, the Company issued 876,623 OP units (including 13,475 OP units in the Company's DownREIT partnerships) in satisfaction of such conversion requests.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2018
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 Interest	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, 2018 , 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 $240.4 million and $248.0 million as of December 31, 2018 and December 31, 2017 , 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 $138.4 million and $140.3 million as of December 31, 2018 and December 31, 2017 , 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 and 40 years ; furniture and equipment are depreciated over estimated useful lives primarily between three and 10 years . 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, 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 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.
Cost of Raising Capital	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	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 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 and Management fees and other revenue	Other property-related revenue Other property-related revenue 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, 2018 , 2017 and 2016 , the Company recognized $7.5 million , $6.0 million and $4.2 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, 2018 , 2017 and 2016 , the Company recognized retail sales of $1.5 million , $1.3 million and $1.0 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, 2018 , 2017 and 2016 , the Company recognized property management fees, call center fees and platform fees of $7.8 million , $4.8 million and $1.1 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 year life of the unconsolidated real estate ventures and as such, the Company's performance obligation for these acquisition fees are satisfied over a four year period. As of December 31, 2018 and 2017 , the Company had deferred revenue related to the acquisition fees of $4.6 million and $2.8 million , respectively. 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, 2018 , 2017 and 2016 , the Company recognized acquisition fees of $1.6 million , $1.5 million and $0.3 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, 2018 , 2017 and 2016 , the Company recognized $2.4 million , $1.9 million and $0.5 million , respectively, of revenue related to these activities.
Advertising Costs	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.
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, 2018 and 2017 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 Through December 31, 2014, the Company did not have a profit and loss sharing interest in its operating partnership and did not have any other operations that were subject to taxation. Accordingly, the Company did not generate a federal income tax benefit or expense for the period from its inception through December 31, 2014. 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, 2018 and 2017 . The Company did not have any unrecognized tax benefits related to uncertain tax positions as of December 31, 2018 and 2017 . 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 2015 tax year is the earliest period that remains open to examination by these taxing jurisdictions.
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 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	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 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.
Reclassifications	Reclassifications Certain amounts in the consolidated financial statements and related notes have been reclassified to conform to the current year presentation. Such reclassifications do not impact the Company's previously reported financial position or net income (loss).
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 unitholders. Accordingly, the Company allocates GAAP income (loss) utilizing the hypothetical liquidation at book value ("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 13. 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).
Assets Held For Sale	Assets Held For Sale The Company classifies properties as held for sale when certain criteria are met. At such time, the properties, including significant assets and liabilities that are expected to be transferred as part of a sale transaction, are presented separately on the consolidated balance sheet at the lower of carrying value or estimated fair value less costs to sell and depreciation is no longer recognized. As of December 31, 2017 , the Company had one self storage property classified as held for sale. The results of operations for the self storage properties classified as held for sale are reflected within income from operations in the Company's consolidated statements of operations.
Goodwill	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.
Use of Estimates	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	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The Company adopted ASU 2014-09 effective January 1, 2018, and concluded that its adoption of ASU 2014-09 had no material effect on its consolidated financial statements as most of the Company's revenue is derived from lease contracts, which are excluded from the scope of the new guidance. For the Company’s other property-related revenue and management fees and other revenue subject to the new guidance, the Company performed an evaluation which included identifying its performance obligations and when such performance obligations are satisfied. Based on this evaluation, the Company determined that there was no material change in the timing or pattern of recognition of revenue for these activities as compared to the application of previous revenue recognition guidance. In February 2016, the 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. ASU 2016-02 initially required a modified retrospective approach, with entities applying the new guidance at the beginning of the earliest period presented in the financial statements in which they first apply the new standard, with certain elective transition relief. 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. The Company elected the package of practical expedients which permits the Company 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. As a lessor, the Company's recognition of rental revenue remained consistent with previous guidance, and the adoption of the lease standard did not change the Company's consolidated statements of operations and did not result in a cumulative catch-up adjustment to opening equity. Adoption of the lease standard will have a material impact on the Company's consolidated balance sheets for its non-cancelable leasehold interest agreements in which it is the lessee. As a lessee, the Company expects to record lease liabilities of approximately $24 million with corresponding right-of-use assets of approximately $23 million. See Note 12 for additional detail about the Company's non-cancelable leasehold interest agreements.
