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 completed its initial public offering on April 28, 2015 and 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 metropolitan statistical areas ("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 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 444 self storage properties in 26 states with approximately 27.2 million rentable square feet (unaudited) in approximately 215,000 storage units as of December 31, 2017 . 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").

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, 2017 , 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 $248.0 million and $256.8 million as of December 31, 2017 and December 31, 2016 , 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 $140.3 million and $41.4 million as of December 31, 2017 and December 31, 2016 , 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 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 Company's customers. Amortization expense for customer in-place leases amounted to $13.5 million , $12.0 million and $12.0 million for the years ended December 31, 2017 , 2016 and 2015 , respectively. 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 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 consists of ancillary revenues such as tenant insurance-related access fees and commissions and sales of storage supplies which are recognized in the period earned. The Company recognizes gains from disposition of facilities only upon closing in accordance with the guidance on sales of real estate. Payments received from purchasers prior to closing are recorded as deposits. Profit on real estate sold is recognized using the full accrual method upon closing when the collectability of the sales price is reasonably assured and the Company is not obligated to perform significant activities after the sale. Profit may be deferred in whole or part until the sale meets the requirements of profit recognition on sales under this guidance. The Company earns management and other fees for managing and operating its unconsolidated real estate venture. These fees include property management fees, call center fees, platform fees, acquisition fees, development fees and a portion of tenant warranty protection proceeds. The Company recognizes these fees when they are earned, fixed and determinable. The fees are reported in management fees and other revenue in the Company's consolidated statements of operations. 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 $3.7 million , $3.1 million and $2.4 million for the years ended December 31, 2017 , 2016 and 2015 , 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 year ended December 31, 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, 2017 and 2016 . The Company did not have any unrecognized tax benefits related to uncertain tax positions as of December 31, 2017 and 2016 . 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 2014 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, including awards that vested upon completion of the Company's initial public offering, 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 Venture The Company’s investment in its unconsolidated real estate venture is recorded under the equity method of accounting in the accompanying consolidated financial statements. Under the equity method, the Company’s investment in real estate venture is 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 venture. The Company follows the "look through" approach for classification of distributions from joint ventures in its consolidated statements of cash flows. Under this approach, distributions are reported under operating cash flow unless the facts and circumstances of a specific distribution clearly indicate that it is a return of capital (e.g., proceeds from the unconsolidated real estate venture’s sale of assets), in which case it is reported as an investing activity. 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 amongst 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 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 and 2016, the Company had one and two self storage properties classified as held for sale, respectively. 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, 2017 and 2016. 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 has completed its analysis of ASU 2014-09 and concluded that its adoption of ASU 2014-09 will not have a material effect on its consolidated financial statements and related disclosures. The Company adopted ASU 2014-09 effective January 1, 2018. 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. The Company will adopt ASU 2016-02 effective January 1, 2019. ASU 2016-02 requires 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. The Company is evaluating the effect that ASU 2016-02 will have on its operating leases, consolidated financial statements and related disclosures. The Company expects ASU 2016-02 to primarily impact its accounting for its non-cancelable leasehold interest agreements in which it serves as the lessee. See Note 12 for additional information about the Company's non-cancelable leasehold interest agreements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows, which clarifies the classification of certain cash receipts and cash payments in the statement of cash flows, including debt prepayment or extinguishment costs, settlement of contingent consideration arising from a business combination, insurance settlement proceeds, and distributions from certain equity method investees. The Company adopted ASU 2016-15 effective January 1, 2017, which did not result in any changes to the presentation of amounts shown on the Company's consolidated statements of cash flows to all periods presented. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows - Restricted Cash, that requires the inclusion of restricted cash and restricted cash equivalents with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The Company adopted ASU 2016-18 effective January 1, 2017, which resulted in the inclusion of the Company's restricted cash balances along with cash and cash equivalents in the Company's consolidated statement of cash flows and separate line items showing changes in restricted cash balances were eliminated from the Company's consolidated statements of cash flows. ASU 2016-18 was applied retrospectively to all periods presented. In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities, which amends the existing GAAP hedge accounting recognition and presentation requirements. ASU 2017-12 is effective for the Company on January 1, 2019, with early adoption permitted. The Company has completed its analysis of ASU 2017-12 and concluded that its adoption of ASU 2017-12 will not have a material effect on its consolidated financial statements and related disclosures. The Company early adopted ASU 2017-12 effective January 1, 2018.

Equity [Abstract]
SHAREHOLDERS' EQUITY AND NONCONTROLLING INTERESTS	SHAREHOLDERS' EQUITY AND NONCONTROLLING INTERESTS Shareholders' Equity The Company completed its initial public offering on April 28, 2015, pursuant to which it sold 23,000,000 of its common shares, at a price of $13.00 per share, which included 3,000,000 common shares sold upon the exercise in full by the underwriters of their option to purchase additional shares. These transactions resulted in net proceeds to the Company of approximately $278.1 million , after deducting the underwriting discount and before additional expenses associated with the offering. Common Share Offerings On December 11, 2017, the Company closed a follow-on public offering of 5,750,000 of its common shares, which included 750,000 common shares sold upon the exercise in full by the underwriters of their option to purchase additional common shares, at a public offering price of $ 25.50 per share. The Company received aggregate net proceeds from the offering of approximately $140.3 million after deducting the underwriting discount and additional expenses associated with the offering. On July 6, 2016, the Company closed a follow-on public offering of 12,046,250 of its common shares, which included 1,571,250 common shares sold upon the exercise in full by the underwriters of their option to purchase additional common shares, at a public offering price of $20.75 per share. The Company received aggregate net proceeds from the offering of approximately $237.5 million after deducting the underwriting discount and additional expenses associated with the offering.

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. At the Market ("ATM") Program On October 11, 2016, the Company entered into open market sales agreements with four agents, pursuant to which the Company may sell from time to time up to $200 million of the Company's common shares in sales deemed to be "at the market offerings." The Company may offer the common shares through the agents, as sales agents, or to the agents, acting as principals by means of, among others, ordinary brokers’ transactions on the NYSE or otherwise at market prices prevailing at the time of sale or at negotiated prices. During the year ended December 31, 2016 , the Company sold 1,740,959 of its common shares through the ATM program. The common shares were sold at an average offering price of $19.54 per share, resulting in net proceeds to the Company of approximately $33.6 million after deducting compensation payable by the Company to such agents, but before expenses. 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 our 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 limited partner equity interests in the Company's 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. 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, 2017 and 2016 , units reflecting noncontrolling interests consisted of the following: December 31, 2017 2016 OP units 26,719,607 26,125,444 Subordinated performance units 11,604,738 11,022,378 LTIP units 771,396 1,543,905 DownREIT units DownREIT OP units 1,834,786 1,834,786 DownREIT subordinated performance units 4,386,999 4,386,999 Total 45,317,526 44,913,512 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. Accordingly, these limited partner interests are included in noncontrolling interests within equity in the accompanying balance sheets as of December 31, 2017 and 2016 . The increase in OP Units outstanding from December 31, 2016 to December 31, 2017 was due to 1,022,718 OP units issued in connection with the acquisition of self storage properties and 992,210 LTIP units which were converted into OP units, as discussed further below, partially offset by the redemption of 1,409,715 OP units and 11,050 OP units which were converted into subordinated performance units. 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 increase in subordinated performance units outstanding from December 31, 2016 to December 31, 2017 was due to the issuance of 300,043 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), the issuance of 271,267 subordinated performance units in connection with the acquisition of self storage properties and 11,050 OP units which were converted into subordinated performance units. LTIP Units LTIP units are a special class of partnership interest in the Company's operating partnership that allow the holder to participate in the ordinary and liquidating distributions received by holders of the OP units (subject to the achievement of specified levels of profitability by the Company's operating partnership or the achievement of certain events). LTIP units may also, under certain circumstances, be convertible into OP units on a one -for-one basis, which are then exchangeable for common shares as described above. LTIP units do not have full parity with OP units with respect to liquidating distributions and may not receive ordinary distributions until such parity is reached pursuant to the terms of the LP Agreement. If such parity is reached under the LP Agreement, upon vesting, vested LTIP units may be converted into an equal number of OP units, and thereafter have all the rights of OP units, including redemption rights. See Note 9 for additional information about the Company's LTIP Units. The decrease in LTIP units outstanding from December 31, 2016 to December 31, 2017 was due to the conversion of 992,210 LTIP units into 992,210 OP units partially offset by the issuance of 219,701 compensatory LTIP units to employees, consultants and trustees.

Equity Method Investments and Joint Ventures [Abstract]
INVESTMENT IN UNCONSOLIDATED REAL ESTATE VENTURE	INVESTMENT IN UNCONSOLIDATED REAL ESTATE VENTURE During the year ended December 31, 2016, the Company, through a newly formed subsidiary (the "NSA Member"), entered into an agreement to form an unconsolidated real estate venture (the "Joint Venture") with a state pension fund (the "JV Investor," together with the NSA Member, the "Members") advised by Heitman Capital Management LLC to acquire and operate the 66 -property "iStorage" facilities portfolio (the "JV Portfolio") for an aggregate purchase price of approximately $630.0 million (the "Acquisition"). On October 4, 2016, the Joint Venture completed its acquisition of the JV Portfolio. The Joint Venture financed the Acquisition with approximately $320.0 million in equity (approximately $80.0 million from the NSA Member in exchange for a 25% ownership interest and approximately $240.0 million from the JV Investor in exchange for a 75% ownership interest) with the balance of the purchase price funded using proceeds from new debt financing. During the year ended December 31, 2017 , the Joint Venture acquired five self storage properties with an aggregate fair value of $59.3 million . The Company contributed $14.9 million to the Joint Venture to fund the acquisitions. As of December 31, 2017. the Joint Venture portfolio consisted of 71 properties containing approximately 4.9 million rentable square feet (unaudited), configured in approximately 39,000 storage units and located across 13 states. A subsidiary of the Company is acting as the non-member manager of the Joint Venture (the "NSA Manager"). The Joint Venture pays certain customary fees to the Company for managing and operating the properties, including a monthly property management fee equal to 6% of gross revenues and net sales revenues from Joint Venture assets, an annual call center fee equal to 1% of monthly gross revenues and net sales revenues from Joint Venture assets, a monthly platform fee equal to $1,250 per Joint Venture property, an acquisition fee equal to 0.65% of the gross capitalization (including debt and equity) of the original JV Portfolio, of which one quarter is earned each year over the first four years of the Joint Venture, with an additional fee determined on a sliding scale for future acquisitions, and a development management fee for any development projects acquired by the Joint Venture equal to 3% of construction costs (excluding "soft costs"). An affiliate of the NSA Manager provides tenant warranty protection to tenants at the Joint Venture properties in exchange for 50% of all proceeds from the tenant warranty protection program at each Joint Venture property. During the year ended December 31, 2017 and December 31, 2016 , the Company earned $8.1 million and $1.8 million , respectively, of management and other fees for managing and operating its Joint Venture. The fees are reported in management fees and other revenue in the Company's consolidated statements of operations. The Company's investment in the Joint Venture is accounted for using the equity method of accounting and is included in investment in unconsolidated real estate venture in the Company’s consolidated balance sheets. The Company's investment in the unconsolidated real estate venture totaled $89.1 million and $81.5 million as of December 31, 2017 and December 31, 2016 , respectively. This investment includes $3.7 million of direct costs incurred by the Company primarily related to sourcing joint venture partner capital. Due to the nature of these costs, this additional investment basis is not amortized. The Company’s earnings (losses) from its investment in the Joint Venture is presented in equity in losses of unconsolidated real estate venture on the Company’s consolidated statements of operations and totaled $2.3 million and $1.5 million for the years ended December 31, 2017 and December 31, 2016 , respectively. The following tables present condensed financial information of the Joint Venture as of and for the year ended December 31, 2017 and as of and for the period ended December 31, 2016 (in thousands): December 31, 2017 December 31, 2016 ASSETS Self storage properties, net $ 655,973 $ 614,754 Other assets 8,397 19,936 Total assets $ 664,370 $ 634,690 LIABILITIES AND EQUITY Debt financing $ 317,359 $ 317,047 Other liabilities 4,855 4,498 Equity 342,156 313,145 Total liabilities and equity $ 664,370 $ 634,690 Year Ended Period Ended December 31, 2016 Total revenue $ 54,747 $ 12,197 Property operating expenses 18,463 3,850 Net operating income 36,284 8,347 Supervisory, administrative and other expenses (3,921 ) (949 ) Depreciation and amortization (29,192 ) (6,235 ) Interest expense (11,389 ) (2,823 ) Acquisition and other expenses (1,146 ) (4,277 ) Net loss $ (9,364 ) $ (5,937 ) Separately, the Company, through certain newly formed subsidiaries, agreed to acquire the iStorage property management platform related to the JV Portfolio, including a property management company, a captive insurance company, and related intellectual property for $20.0 million . On October 4, 2016, the Company completed its acquisition of the property management platform. The property management platform was accounted for as a business combination whereby the Company allocated the total purchase price to the estimated fair value of tangible and intangible assets acquired, and liabilities assumed. The Company allocated a portion of the purchase price to tangible fixed assets of $0.4 million and intangible assets consisting of the management contract with an estimated fair value of $10.6 million and the iStorage trade name with an estimated fair value of $3.2 million . The excess of the aggregate consideration paid for the property management platform over the identified assets acquired and liabilities assumed, equal to $5.8 million , was allocated to goodwill. The tangible and intangible assets related to the property management platform are reported in other assets, net in the Company's consolidated balance sheets. The Company’s fair value measurements were based, in part, on valuations prepared by an independent valuation firm and the allocation of the property management platform purchase price required a significant amount of judgment. The Company measured the fair value of the management contract based on discounted future cash flows expected under the management contract. Neither the management contract nor the Joint Venture have a finite term. Accordingly, the Company assigned probabilities to the term of the Joint Venture and the Company’s management relationship with the Joint Venture using the Company’s best estimates and assumptions. The management contract asset is charged to amortization expense on a straight-line basis over 15 years , which represents the time period over which the majority of value was attributed in the Company’s discounted cash flow model. The Company measured the fair value of the trade name, which has an indefinite life and is not amortized, using the relief from royalty method. The results of operations for the property management platform are included in the Company's statements of operations beginning on October 4, 2016. On an unaudited pro forma basis, after giving effect to the acquisition of the property management platform as if it was acquired on January 1, 2015, the Company would have recorded incremental additional revenue of $4.9 million and $6.3 million for the years ended December 31, 2016 and 2015, respectively, and incremental net income of $0.6 million and $0.7 million for the years ended December 31, 2016 and 2015, respectively. This pro forma information was prepared using the following significant assumptions: the Joint Venture acquired the JV Portfolio and the management contract was effective on January 1, 2015; the Company financed the purchase price of the property management platform through borrowings under its Revolver with interest computed based on the effective interest rate of 2.17% as of December 31, 2016; and assumed depreciation and amortization expense is based on the actual acquisition-date fair values and useful lives assigned to tangible fixed assets and the management contract. The unaudited pro forma information in the paragraph above does not purport to represent what the actual results of operations would have been for the periods indicated, nor does it purport to represent the Company's future results of operations. The pro forma information was prepared using audited and unaudited historical financial information related to the JV Portfolio obtained by the Company as part of its underwriting and due diligence process and does not give effect to any assumptions about improved operating performance of the JV Portfolio under the management of the NSA Manager nor does it give effect to potential property acquisitions by the Joint Venture, as such assumptions would require projections and estimates of management’s intentions that are not factually supportable.

Unaudited Pro Forma Financial Information For 2016 Business Combinations The Company acquired 107 self storage properties during the year ended December 31, 2016 that were accounted for as business combinations. On a pro forma basis, after giving effect to the acquisition of 100 of the 107 self storage properties as if they were acquired on January 1, 2015 (pro forma financial information is not presented for seven of the self storage properties acquired during the year ended December 31, 2016 since the information required is not available to the Company), the Company would have recorded incremental additional revenue of $35.5 million and net income of $15.3 million for the year ended December 31, 2016 and additional revenue of $61.2 million and an incremental net loss of $23.1 million for the year ended December 31, 2015. This unaudited pro forma information was prepared using the following significant assumptions: (i) for the cash portion of the purchase price, the Company assumed borrowings under the Company's revolving line of credit with interest computed based on the effective interest rate of 2.17% as of December 31, 2016 ; (ii) for assumed debt financing directly associated with the acquisition of specific self storage properties, interest was computed for the entirety of the periods presented using the effective interest rates under such financings; and (iii) for acquisition costs $6.5 million incurred during the year ended December 31, 2016 , pro forma adjustments give effect to these costs as if they were incurred on January 1, 2015. The unaudited pro forma information presented in the paragraph above does not purport to represent what the actual results of operations would have been for the periods indicated, nor does it purport to represent the Company's future results of operations. As described in greater detail above, given that certain information with respect to the business combinations is not available to the Company, readers of this Form 10-K and investors are cautioned not to place undue reliance on the Company's unaudited pro forma financial information.

Effective interest rate incorporates the stated rate plus the impact of interest rate cash flow hedges and discount and premium amortization, if applicable. For the revolving line of credit, the effective interest rate excludes fees for unused borrowings. Credit Facility The Company has an unsecured credit facility with a syndicated group of lenders, which, as of December 31, 2017 , provided for total borrowings of $895.0 million consisting of four components: (i) a Revolver which provides for a total borrowing commitment up to $400.0 million , whereby the Company may borrow, repay and re-borrow amounts under the Revolver, (ii) a $235.0 million Term Loan A, (iii) a $155.0 million Term Loan B, and (iv) a $105.0 million Term Loan C.

The Term Loan A matures in May 2021, the Term Loan B matures in May 2022 and the Term Loan C matures in February 2024. The Revolver, Term Loan A, Term Loan B and Term Loan C are not subject to any scheduled reduction or amortization payments prior to maturity. Interest rates applicable to loans under the credit facility are determined based on a 1, 2, 3 or 6 month LIBOR period (as elected by the Company at the beginning of any applicable interest period) plus an applicable margin or a base rate, determined by the greatest of the Key Bank prime rate, the federal funds rate plus 0.50% or one month LIBOR plus 1.00% , plus an applicable margin.

The Company is also required to pay the following usage based fees ranging from 0.15% to 0.25% with respect to the unused portion of the Revolver; provided that if the Company makes an investment grade pricing election as described in the preceding sentence, the Company will be required to pay rating based fees ranging from 0.125% to 0.300% with respect to the entire Revolver in lieu of any usage based fees. As of December 31, 2017 , the Company had outstanding letters of credit totaling $4.7 million and would have had the capacity to borrow remaining Revolver commitments of $306.8 million while remaining in compliance with the credit facility's financial covenants described in the following paragraph. The Company is required to comply with the following financial covenants under the credit facility: • Maximum total leverage ratio not to exceed 60% • Minimum fixed charge coverage ratio of at least 1.5 x • Minimum net worth of at least $682.6 million plus 75% of future equity issuances • Maximum unsecured debt to unencumbered asset value ratio not to exceed 60% • Unencumbered adjusted net operating income to unsecured interest expense of at least 2.0 x In addition, the terms of the credit facility contain customary affirmative and negative covenants that, among other things, limit the Company's ability to make distributions or certain investments, incur debt, incur liens and enter into certain transactions.

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, 2017 , 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, 2017 , an aggregate of 2,474,710 LTIP units have been issued under the 2013 Plan, 396,471 LTIP units have been issued under the 2015 Plan, and 313,585 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 January 1, 2020. 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 $3.5 million , $2.5 million and $3.0 million for the years ended December 31, 2017 , 2016 and 2015 , respectively. At December 31, 2017 , total unvested compensation cost not yet recognized was $3.4 million . The Company expects to recognize this compensation cost over a period of approximately 2.0 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, 2017 , 2016 and 2015 : Time-Based LTIP Unit Awards 2017 2016 2015 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 294,529 $ 14.74 236,265 $ 10.41 509,166 $ 10.07 Granted 128,051 22.89 177,546 17.59 6,000 13.00 Vested (194,814 ) 13.43 (119,282 ) 10.41 (278,901 ) 9.84 Unvested at end of year 227,766 $ 20.37 294,529 $ 14.74 236,265 $ 10.41 The aggregate fair value of the time-based LTIP unit awards that vested during the years ended December 31, 2017 , 2016 and 2015 was $2.6 million , $1.2 million and $2.7 million , respectively. The following table summarizes activity for the performance-based LTIP unit awards granted during the year ended December 31, 2017 , including the 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. Performance-Based LTIP Unit Awards Minimum Target Maximum Weighted Average Grant-Date Fair Value Outstanding unvested at December 31, 2016 — — — $ — Granted — 40,390 90,874 27.63 Outstanding unvested at December 31, 2017 — 40,390 90,874 $ 27.63 The fair value of the performance-based LTIP unit awards, which have a market condition, is estimated on the date of grant using a Monte Carlo simulation. 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 year ended December 31, 2017: 2017 Risk-free interest rate 1.58 % Dividend yield 4.35 % Expected volatility 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, 2017 , 2016 and 2015 : Total LTIP units Total unvested units, December 31, 2014 522,900 Units vested in 2015 related to properties contributed or sourced by PROs (99,100 ) 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 The aggregate fair value of purchase consideration recognized during the years ended December 31, 2017 , 2016 and 2015 was $0.9 million , $0.8 million and $1.4 million , respectively. As of December 31, 2017 , 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, 2017 , 2016 and 2015 , the Company issued 776 , 2,758 and 88,981 LTIP units, respectively, that were immediately vested to consultants that provided acquisition services. As a result of the Company's adoption of ASU 2017-01 during the year ended December 31, 2017 , the self storage properties acquired during the year ended December 31, 2017 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 the Company's adoption of ASU 2017-01, 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 years ended December 31, 2016 and 2015 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 , $0.1 million and $1.0 million for the years ended December 31, 2017 , 2016 and 2015 , respectively. Restricted Common Shares Through December 31, 2017 , an aggregate of 41,825 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.

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, 2017 , 2016 and 2015 (in thousands, except per share amounts): Year Ended December 31, 2017 2016 2015 Earnings (loss) per common share - basic and diluted Numerator Net income $ 45,998 $ 24,866 $ 4,796 Net (income) loss attributable to noncontrolling interests (43,037 ) (6,901 ) 7,644 Net income attributable to National Storage Affiliates Trust 2,961 17,965 12,440 Distributions to preferred shareholders (2,300 ) — — Distributed and undistributed earnings allocated to participating securities (28 ) (18 ) (9 ) Net income attributable to common shareholders - basic 633 17,947 12,431 Effect of assumed conversion of dilutive securities — 6,783 (4,919 ) Net income attributable to common shareholders - diluted $ 633 $ 24,730 $ 7,512 Denominator Weighted average shares outstanding - basic 44,423 29,887 15,463 Effect of dilutive securities: Weighted average OP units outstanding — 24,262 15,697 Weighted average DownREIT OP unit equivalents outstanding — 1,835 1,171 Weighted average LTIP units outstanding — 1,846 1,272 Weighted average subordinated performance units and DownREIT subordinated performance unit equivalents — 20,917 11,806 Weighted average shares outstanding - diluted 44,423 78,747 45,409 Earnings (loss) per share - basic $ 0.01 $ 0.60 $ 0.80 Earnings (loss) per share - diluted $ 0.01 $ 0.31 $ 0.17 Dividends declared per common share $ 1.04 $ 0.88 $ 0.54 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. Additionally, the Company did not have an ownership interest or share in its operating partnership's profits and losses prior to the completion of the Company's initial public offering. As a result, all of the operating partnership's profits and losses for the period from January 1, 2015 to April 28, 2015 were allocated to noncontrolling interests. 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, 2017 , 318,640 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, 2017 , 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 year ended December 31, 2017 , potential common shares totaling 50.6 million , 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.

During the year s ended December 31, 2017 , 2016 and 2015 , the Company incurred $14.4 million , $11.0 million and $7.6 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 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, 2017 , 2016 and 2015 , the Company incurred $24.6 million , $19.4 million and $13.4 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, 2017 , 2016 and 2015 , the Company incurred $0.7 million , $1.1 million and $0.6 million , respectively, of expenses payable to certain PROs related to self storage property acquisitions sourced by the PROs.

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, 2017 and 2016 , the Company received above-market interest reimbursements from the sellers totaling $1.3 million and $1.4 million , respectively. In addition, in exchange for $1.3 million and $1.4 million of principal payment reimbursements received related to these assumed mortgages during the year s ended December 31, 2017 and 2016 , the Company issued 47,339 and 67,832 OP units to the sellers during the year ended December 31, 2017 and 2016 .

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Operating Leases The Company has six properties that are subject to non-cancelable leasehold interest agreements that are classified as operating leases. These lease agreements expire between 2034 and 2092, inclusive of extension options that the Company anticipates exercising. To the extent that the leasehold interest agreements provide for fixed increases throughout the term of the lease, the Company recognizes lease expense on a straight-line basis over the expected lease terms. Rent expense under these leasehold interest agreements are included in property operating expenses in the accompanying statements of operations and amounted to $1.2 million , $1.1 million and $1.0 million for the years ended December 31, 2017 , 2016 and 2015 , respectively. In March 2014, the Company entered into a non-cancelable operating lease that expires in July 2020 for its corporate headquarters in Greenwood Village, Colorado. Under the terms of the office lease, the Company obtained an option to extend the lease for an additional term of five years at then current market rates. The office lease provides for an abated rent period and the value of this inducement is being accounted for as a reduction to rent expense over the term of the lease. Rent expense related to this office lease is included in general and administrative expenses in the accompanying statements of operations and amounted to $0.2 million , $0.1 million and $0.1 million for the years ended December 31, 2017 , 2016 and 2015 , respectively. As of December 31, 2017 , future minimum cash payments under the Company's operating leases are as follows (in thousands): Year Ending December 31, Real Estate Leasehold Interests Office Lease Total 2018 $ 1,329 $ 184 $ 1,513 2019 1,334 188 1,522 2020 1,379 112 1,491 2021 1,404 — 1,404 2022 1,419 — 1,419 2023 through 2092 37,498 — 37,498 $ 44,363 $ 484 $ 44,847 Legal Proceedings The Company is subject to litigation, claims, and assessments that may arise in the ordinary course of its business activities.

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, 2015 $ (972 ) Designation of interest rate swap as a cash flow hedge 19 Losses on interest rate swaps reclassified into interest expense from accumulated other comprehensive loss 2,678 Unrealized losses included in accumulated other comprehensive loss 6,434 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 loss 2,308 Unrealized gains included in accumulated other comprehensive loss 1,935 Fair value at December 31, 2017 $ 12,414 As of December 31, 2017 and 2016 , the Company had outstanding interest rate swaps designated as cash flow hedges with aggregate notional amounts of $595.0 million and $425.0 million , respectively. As of December 31, 2017 , the Company's swaps had a weighted average remaining term of 3.5 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, 2017 remain constant, the Company estimates that during the next 12 months , the Company would reclassify into earnings approximately $1.1 million of the unrealized losses included in accumulated other comprehensive loss. If market interest rates increase above the 1.51% 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, 2017 and 2016 . 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, 2017 and 2016 , 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, 2017 and 2016 , 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, 2017 and 2016 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 $271.5 million as of December 31, 2017 with a fair value of approximately $282.6 million . In determining the fair value, the Company estimated a weighted average market interest rate of approximately 4.04% , compared to the weighted average contractual interest rate of 4.87% . The combined principal balance of the Company's fixed rate mortgages was approximately $201.7 million as of December 31, 2016 with a fair value of approximately $214.0 million . In determining the fair value as of December 31, 2016 , the Company estimated a weighted average market interest rate of approximately 3.89% , compared to the weighted average contractual interest rate of 5.25% .

Subsequent Events [Abstract]
SUBSEQUENT EVENTS	SUBSEQUENT EVENTS Self Storage Property Acquisitions In January and February 2018, the Company acquired 18 self storage properties from third-party sellers for approximately $101.8 million . Consideration for these acquisitions included approximately $78.9 million of net cash, the assumption of $0.5 million of other working capital liabilities and OP equity of approximately $22.4 million (consisting of the issuance of 464,056 OP Units, 316,103 Series A-1 Preferred Units and 56,228 subordinated performance units). Such amounts incorporate the effect of $2.1 million of subordinated equity issued in exchange for cash co-invested by Personal Mini and Move It. The 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 Series A Preferred Shares or the issuance of Series A Preferred Shares on a one-for-one basis, subject to adjustments. In connection with these acquisitions, the Company reimbursed the PROs for $0.2 million of due diligence costs related to the self storage properties sourced by the PROs. In January 2018, the Joint Venture acquired one self storage property with an estimated fair value of $9.3 million . The venture financed the acquisition with capital contributions from the venture members, of which the Company contributed $2.4 million . Credit Facility Increase On January 29, 2018 , pursuant to a full exercise by the Company's operating partnership of its remaining expansion option and a partial exercise of its Additional Expansion Option (defined below) under its credit agreement dated as of May 6, 2016, the Company's operating partnership, as borrower, certain of its subsidiaries that are party to the credit facility, as subsidiary guarantors, and the Company, as parent guarantor, entered into a third increase agreement and amendment (the "Increase Agreement") with a syndicated group of lenders to increase the total borrowing capacity under the Company's credit facility by adding an additional tranche D term loan facility ("Term Loan D") in an aggregate outstanding principal amount of $125.0 million , for a total credit facility of over $1.0 billion consisting of the following components: (i) a $400.0 million Revolver, (ii) Term Loan A, which provides for a total borrowing commitment of up $235.0 million , (iii) Term Loan B, which provides for a total borrowing commitment of up to $155.0 million , (iv) Term Loan C, which provides for a total borrowing commitment of up to $105.0 million and (iv) Term Loan D, which provides for a total borrowing commitment of up to $125.0 million . The Company renewed its expansion option under the credit facility to permit an additional $300.0 million of revolving commitments and/or term loans (the "Additional Expansion Option"), which was partially exercised in the amount of $20.0 million in connection with Term Loan D. If exercised in full, the Additional Expansion Option would provide for a total borrowing capacity under the credit facility of $1.3 billion . The Term Loan D matures on January 29, 2023. It is not subject to any scheduled reduction or amortization payment prior to maturity. Interest rates applicable to loans under Term Loan D are determined based on a 1, 2, 3 or 6 month LIBOR period (as elected by the Company at the beginning of any applicable interest period) plus an applicable margin, or a base rate, determined by the greatest of the Key Bank prime rate, the federal funds rate plus 0.50% or one month LIBOR plus 1.00% , plus an applicable margin. The applicable margins for Term Loan D are leverage based and range from 1.30% to 1.85% for LIBOR loans and 0.30% to 0.85% for base rate loans; provided that after such time as the Company achieves an investment grade rating from at least two rating agencies, the Company may elect (but is not required to elect) that Term Loan D is subject to the rating based on applicable margins ranging from 0.90% to 1.75% for LIBOR Loans and 0.00% to 0.75% for base rate loans. Term Loan D may be prepaid at any time without penalty. Other than the increases and amendments related to Term Loan D and Additional Expansion Option described above, the Increase Agreement did not impact or amend the credit facility's previously disclosed terms, including its covenants, events of default, or terms of payment. 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, 2017 , the Company received voluntary conversion notices for 997,074 subordinated performance units. Effective January 1, 2018, the Company issued 2,024,170 OP units in satisfaction of such voluntary conversions.

SUMMARY OF SIGNIFICANT ACCOUN25

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2017
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, 2017 , 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 $248.0 million and $256.8 million as of December 31, 2017 and December 31, 2016 , 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 $140.3 million and $41.4 million as of December 31, 2017 and December 31, 2016 , 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 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 Company's customers.
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.
Revenue Recognition	Revenue Recognition 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 consists of ancillary revenues such as tenant insurance-related access fees and commissions and sales of storage supplies which are recognized in the period earned. The Company recognizes gains from disposition of facilities only upon closing in accordance with the guidance on sales of real estate. Payments received from purchasers prior to closing are recorded as deposits. Profit on real estate sold is recognized using the full accrual method upon closing when the collectability of the sales price is reasonably assured and the Company is not obligated to perform significant activities after the sale. Profit may be deferred in whole or part until the sale meets the requirements of profit recognition on sales under this guidance. The Company earns management and other fees for managing and operating its unconsolidated real estate venture. These fees include property management fees, call center fees, platform fees, acquisition fees, development fees and a portion of tenant warranty protection proceeds. The Company recognizes these fees when they are earned, fixed and determinable. The fees are reported in management fees and other revenue in the Company's consolidated statements of operations.
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 year ended December 31, 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, 2017 and 2016 . The Company did not have any unrecognized tax benefits related to uncertain tax positions as of December 31, 2017 and 2016 . 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 2014 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, including awards that vested upon completion of the Company's initial public offering, 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 Venture The Company’s investment in its unconsolidated real estate venture is recorded under the equity method of accounting in the accompanying consolidated financial statements. Under the equity method, the Company’s investment in real estate venture is 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 venture. The Company follows the "look through" approach for classification of distributions from joint ventures in its consolidated statements of cash flows. Under this approach, distributions are reported under operating cash flow unless the facts and circumstances of a specific distribution clearly indicate that it is a return of capital (e.g., proceeds from the unconsolidated real estate venture’s sale of assets), in which case it is reported as an investing activity.
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 amongst 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 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 and 2016, the Company had one and two self storage properties classified as held for sale, respectively. 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 has completed its analysis of ASU 2014-09 and concluded that its adoption of ASU 2014-09 will not have a material effect on its consolidated financial statements and related disclosures. The Company adopted ASU 2014-09 effective January 1, 2018. 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. The Company will adopt ASU 2016-02 effective January 1, 2019. ASU 2016-02 requires 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. The Company is evaluating the effect that ASU 2016-02 will have on its operating leases, consolidated financial statements and related disclosures. The Company expects ASU 2016-02 to primarily impact its accounting for its non-cancelable leasehold interest agreements in which it serves as the lessee. See Note 12 for additional information about the Company's non-cancelable leasehold interest agreements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows, which clarifies the classification of certain cash receipts and cash payments in the statement of cash flows, including debt prepayment or extinguishment costs, settlement of contingent consideration arising from a business combination, insurance settlement proceeds, and distributions from certain equity method investees. The Company adopted ASU 2016-15 effective January 1, 2017, which did not result in any changes to the presentation of amounts shown on the Company's consolidated statements of cash flows to all periods presented. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows - Restricted Cash, that requires the inclusion of restricted cash and restricted cash equivalents with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The Company adopted ASU 2016-18 effective January 1, 2017, which resulted in the inclusion of the Company's restricted cash balances along with cash and cash equivalents in the Company's consolidated statement of cash flows and separate line items showing changes in restricted cash balances were eliminated from the Company's consolidated statements of cash flows. ASU 2016-18 was applied retrospectively to all periods presented. In August 2017, the FASB issued ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities, which amends the existing GAAP hedge accounting recognition and presentation requirements. ASU 2017-12 is effective for the Company on January 1, 2019, with early adoption permitted. The Company has completed its analysis of ASU 2017-12 and concluded that its adoption of ASU 2017-12 will not have a material effect on its consolidated financial statements and related disclosures. The Company early adopted ASU 2017-12 effective January 1, 2018.
