Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization	1. ORGANIZATION Global Self Storage, Inc. (the “Company”) is a self-administered and self-managed REIT that owns, operates, manages, acquires, develops and redevelops self storage properties (“stores” or “properties”). The Company’s stores are located in the Northeast, Mid-Atlantic and Mid-West regions of the United States. The Company was formerly registered under the Investment Company Act of 1940, as amended (the “1940 Act”) as a non-diversified, closed end management investment company. The Securities and Exchange Commission’s (“SEC”) order approving the Company’s application to deregister from the 1940 Act was granted on January 19, 2016. Accordingly, effective January 19, 2016, the Company changed its name to Global Self Storage, Inc. from Self Storage Group, Inc., changed its SEC registration to an operating company reporting under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), from an investment company under the 1940 Act, and listed its common stock on the Nasdaq Capital Market (“NASDAQ”) under the symbol “SELF”. The Company has elected to be treated as a REIT under the Internal Revenue Code of 1986, as amended (the “IRC”). To the extent the Company continues to qualify as a REIT, it will not generally be subject to U.S. federal income tax, with certain limited exceptions, on the taxable income that is distributed to its stockholders. The Company invests in self storage properties by acquiring stores through its wholly owned subsidiaries. At December 31, 2017, the Company owned and operated 11 stores. The Company operates primarily in one segment: rental operations. Disclosure of the square footage of the self storage properties is unaudited and outside the scope of our independent registered public accounting firm’s audit of our financial statements in accordance with the standards of the Public Company Accounting Oversight Board (U.S.).

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation Upon deregistration as an investment company, the Company's status changed to an operating company from an investment company since it no longer met the assessment of an investment company under the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946 (“ASC 946”). The Company discontinued applying the guidance in ASC 946 and began to account for the change in status prospectively by accounting for its investments in accordance with other U.S. generally accepted accounting principles (“GAAP”) topics as of the date of the change in status. The consolidated financial statements of the Company are presented on the accrual basis of accounting in accordance with GAAP and include the accounts of the Company and its wholly-owned subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation. Cash and Cash Equivalents Cash and cash equivalents consist of highly liquid investments, and may include money market fund shares, purchased with an original maturity of three months or less. The carrying amount reported on the balance sheet for cash and cash equivalents approximates fair value. Restricted Cash Restricted cash is comprised of escrowed funds deposited with a bank relating to capital expenditures. Income Taxes The Company has elected to be treated as a REIT under the IRC. In order to maintain its qualification as a REIT, among other things, the Company is required to distribute at least 90% of its REIT taxable income to its stockholders and meet certain tests regarding the nature of its income and assets. As a REIT, the Company is not subject to federal income tax with respect to that portion of its income which meets certain criteria and is distributed annually to stockholders. The Company plans to continue to operate so that it meets the requirements for taxation as a REIT. Many of these requirements, however, are highly technical and complex. If the Company were to fail to meet these requirements, it would be subject to federal income tax. In managements opinion, the requirements to maintain these elections are being met. The Company is subject to certain state and local taxes. The Company recognizes the tax benefits of uncertain tax positions only where the position is “more likely than not” to be sustained assuming examination by tax authorities. The Company has reviewed its tax positions and has concluded that no liability for unrecognized tax benefits should be recorded related to uncertain tax positions taken on federal, state, and local income tax returns for open tax years (2014 – 2016), or is expected to be taken in the Company’s 2017 tax returns. Legislation, commonly known as the Tax Cuts and Jobs Act (“TCJA”) was signed into law on December 22, 2017. The TCJA makes significant changes to the U.S. federal income tax rates for taxation of individuals and corporations (including REITs), generally effective for taxable years beginning after December 31, 2017. Investments in Securities Investments in equity securities that have readily determinable fair values are accounted for as available-for-sale. Available-for-sale securities are measured at fair value. Gains or losses from changes in the fair value of available-for-sale securities are recorded in accumulated other comprehensive income, until the investment is sold or otherwise disposed of, or until the investment is determined to be other-than-temporarily impaired, at which time the cumulative gain or loss previously reported in equity is included in income. The specific identification method is used to determine the realized gain or loss on investments sold or otherwise disposed. Fair value is determined using a valuation hierarchy generally by reference to an active trading market, using quoted closing or bid prices. Judgment is used to ascertain if a formerly active market has become inactive and in determining fair values when markets have become inactive. Prior to January 19, 2016, gains and losses from the changes in fair value of investment securities were recorded in the Statement of Operations. Real Estate Assets Real estate assets are carried at the appreciated value as of January 19, 2016, the effective date of the change in status to an operating company, less accumulated depreciation from that date. Purchases subsequent to the effective date of the change in status are carried at cost, less accumulated depreciation. Direct and allowable internal costs associated with the development, construction, renovation, and improvement of real estate assets are capitalized. Property taxes and other costs associated with development incurred during the construction period are capitalized. The construction period begins when expenditures for the real estate assets have been made and activities that are necessary to prepare the asset for its intended use are in progress. The construction period ends when the asset is substantially complete and ready for its intended use. We allocate the net acquisition cost of acquired operating self storage properties to the underlying land, buildings, identified intangible assets, and any noncontrolling interests that remain outstanding based upon their respective individual estimated fair values. Any difference between the net acquisition cost and the estimated fair value of the net tangible and intangible assets acquired is recorded as goodwill. Internal and external transaction costs associated with acquisitions or dispositions of real estate, as well as repairs and maintenance costs, are charged to expense as incurred. Major replacements and betterments that improve or extend the life of the asset are capitalized and depreciated over their estimated useful lives. Depreciation is computed using the straight-line method over the estimated useful lives of the buildings and improvements, which are generally between 5 and 39 years. Accounts Payable and Accrued Expenses Accounts payable and accrued expenses primarily consist of property tax accruals, unearned rental income, and trade payables. At December 31, 2017 and 2016, accounts payable and accrued expenses included a $900,000 contingent payment in connection with the purchase of a property made in 2016. Retained Earnings Retained earnings includes an increase to fair value of the properties owned by the Company at the effective date of the change in status to a reporting company under the Exchange Act (see Footnote 3) and the accumulated net income or loss and accumulated distributions paid since inception. Revenue and Expense Recognition Revenues from stores, which are primarily composed of rental income earned pursuant to month-to-month leases for storage space, as well as associated late charges and administrative fees, are recognized as earned. Promotional discounts reduce rental income over the promotional period. Ancillary revenues from sales of merchandise and tenant insurance and other income are recognized when earned. The Company accrues for property tax expense based upon actual amounts billed and, in some circumstances, estimates and historical trends when bills or assessments have not been received from the taxing authorities or such bills and assessments are in dispute. Cost of operations and general and administrative expense are expensed as incurred. Credit Risk Financial assets that are exposed to credit risk consist primarily of cash and cash equivalents and certain portions of accounts receivable including rents receivable from our tenants. Cash and cash equivalents are on deposit with highly rated commercial banks. Evaluation of Asset Impairment The Company evaluates its real estate assets, intangible assets consisting of in-place lease, and goodwill for impairment annually. If there are indicators of impairment and we determine that the asset is not recoverable from future undiscounted cash flows to be received through the asset’s remaining life (or, if earlier, the expected disposal date), we record an impairment charge to the extent the carrying amount exceeds the asset’s estimated fair value or net proceeds from expected disposal. Stock-based Compensation On October 16, 2017, the Company’s stockholders approved the Company’s 2017 Equity Incentive Plan (the “Plan”). The Plan is designed to provide equity-based incentives to certain eligible persons, as defined in the Plan, in the form of options, share appreciation rights, restricted shares, restricted share units, dividend equivalent rights or other forms of equity-based compensation as determined in the discretion of the Board of Directors, the Compensation Committee of the Board of Directors, or other designee thereof. Awards granted are valued at fair value and any compensation expense is recognized over the service periods of each award. As of December 31, 2017, no awards have been granted under the Plan. Use of Estimates The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the 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 materially differ from management’s estimates. Recently Issued Accounting Standards In February 2017, as part of the new revenue standard, the FASB issued ASU No. 2017-05 – Other Income – Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance, which focuses on recognizing gains and losses from the transfer of nonfinancial assets in contracts with non-customers. Specifically, the new guidance defines “in substance nonfinancial asset,” unifies guidance related to partial sales of nonfinancial assets, eliminates rules specifically addressing sales of real estate, removes exceptions to the financial asset derecognition model, and clarifies the accounting for contributions of nonfinancial assets to joint ventures. The new guidance is effective on January 1, 2018. Upon adoption, the Company expects that the majority of its sale transactions will be treated as dispositions of nonfinancial assets rather than dispositions of a business given the FASB’s recently revised definition of a business (see ASU No. 2017-01 below). Additionally, in partial sale transactions where the Company sells a controlling interest in real estate but retains a noncontrolling interest, the Company expects to now fully recognize a gain or loss on the fair value measurement of the retained interest as the new guidance eliminates the partial profit recognition model. In January 2017, the FASB issued ASU 2017-01 - Business Combinations (Topic 805): Clarifying the Definition of a Business, which changes the definition of a business to include an input and a substantive process that together significantly contribute to the ability to create outputs which are defined as the results of inputs and substantive processes that provide goods or services to customers, other revenue, or investment income. The standard is effective on January 1, 2018. Upon adoption of the new guidance, the Company expects that the majority of future property acquisitions will now be considered asset acquisitions, resulting in the capitalization of acquisition related costs incurred in connection with these transactions and the allocation of purchase price and acquisition related costs to the assets acquired based on their relative fair values. In November 2016, the FASB issued ASU No. 2016-18 - Statement of Cash Flows (Topic 230): Restricted Cash, which requires the statement of cash flows to explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The new guidance also requires entities to reconcile such total to amounts on the balance sheet and disclose the nature of the restrictions. The standard is effective on January 1, 2018. The standard requires the use of the retrospective transition method. The adoption of this guidance will not have a material impact on the Company’s consolidated financial statements as the update relates to financial statement presentation and disclosures. In August 2016, the FASB issued ASU No. 2016-15 - Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. The eight items that the ASU provides classification guidance on include (1) debt prepayment and extinguishment costs, (2) settlement of zero-coupon debt instruments, (3) contingent consideration payments made after a business combination, (4) proceeds from the settlement of insurance claims, (5) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, (6) distributions received from equity method investments, (7) beneficial interests in securitization transactions, and (8) separately identifiable cash flows and application of the predominance principle. The standard became effective on January 1, 2018. The standard requires the use of the retrospective transition method. The adoption of this guidance will not have a material impact on the Company’s consolidated financial statements as the update relates to financial statement presentation and disclosures. In March 2016, the FASB issued ASU No. 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which is intended to simplify various aspects related to how share-based payments are accounted for and presented in the financial statements. The new guidance allows for entities to make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. In addition, the guidance allows employers to withhold shares to satisfy minimum statutory tax withholding requirements up to the employees’ maximum individual tax rate without causing the award to be classified as a liability. The guidance also stipulates that cash paid by an employer to a taxing authority when directly withholding shares for tax-withholding purposes should be classified as a financing activity on the statement of cash flows. The standard became effective on January 1, 2017. The adoption of this guidance did not have an impact on the Company’s consolidated financial position or results of operations. In February 2016, the FASB issued ASU No. 2016-02 - Leases (Topic 842), which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either financing or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. The new standard requires 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. The standard is effective on January 1, 2019, however early adoption is permitted. The Company does not believe this standard will have a material impact on operating results of financial condition, because all lease revenues are derived from month to month self storage leases and the Company does not incur a material amount of lease expense. In January 2016, the FASB issued ASU 2016-01, Financial Instruments – Overall (Subtopic 825-10). The updated accounting guidance, among other things, requires that all nonconsolidated equity investments, except those accounted for under the equity method, be measured at fair value and that the changes in fair value be recognized in net income. The updated guidance is effective for the Company as of January 1, 2018. With certain exceptions, the updated accounting guidance requires a cumulative effect adjustment to beginning retained earnings in the year the guidance is adopted. If we had adopted the provisions of the updated guidance as of January 1, 2017 for our equity investments classified as available-for-sale securities, net income attributable to such securities would have increased by approximately $78,000 in 2017. In May 2014, the FASB issued ASU No. 2014-09 - Revenue from Contracts with Customers (Topic 606), 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 new guidance outlines a five-step process for customer contract revenue recognition that focuses on transfer of control as opposed to transfer of risk and rewards. The new guidance also requires enhanced disclosures regarding the nature, amount, timing, and uncertainty of revenues and cash flows from contracts with customers. In May 2016, the FASB issued ASU 2016-12 - Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, which amends ASU 2014-09 and is intended to address implementation issues that were raised by stakeholders. ASU 2016-12 provides practical expedients on collectability, noncash consideration, presentation of sales tax and contract modifications and completed contracts in transition. Both standards became effective on January 1, 2018. The standards will not have a material impact on the Company’s consolidated statements of financial position or results of operations primarily because the majority of its revenue is derived from lease contracts, which are excluded from the scope of the new guidance. The Company’s insurance fee revenue, and merchandise sale revenue are included in the scope of the new guidance, however, the Company identified similar performance obligations under this standard as compared with deliverables and separate units of account identified under its previous revenue recognition methodology. Accordingly, revenue recognized under the new guidance will not differ materially from revenue recognized under previous guidance and there will be no material prior year impact.

Change In Status [Abstract]
Change in Status	3. CHANGE IN STATUS Prior to the January 19, 2016 change in status as a registered investment company, the Company recorded its investment in the self storage properties at fair value and recorded the changes in the fair value as an unrealized gain or loss. Upon the effective date of the deregistration of the Company as a registered investment company, the fair value accounting as a registered investment company was no longer applicable to the Company, rather the Company began presenting on a consolidated basis, the underlying assets and liabilities of the self storage properties. The Company’s initial carrying value of the net assets of the self storage properties was the fair value on the effective date of the change in status determined as follows: Fair value of self storage properties on the effective date of the change in status $ 34,624,573 Total net assets of the combined self storage properties Property plant and equipment - self storage $ 26,388,167 Cash and cash equivalents 464,585 Accounts receivable 87,103 Prepaid expenses and other assets 206,146 Accounts payable and accrued expenses (488,514 ) 26,657,487 Increase to the initial carrying value of the net assets of the self storage properties on the effective date of the change in status $ 7,967,086

Fair Value Disclosures [Abstract]
Fair Value Measurements	7. FAIR VALUE MEASUREMENTS GAAP establishes a valuation hierarchy for disclosure of the inputs to valuation used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration. Level 3 inputs are unobservable inputs based on our own assumptions used to measure assets and liabilities at fair value. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The following table provides the assets and liabilities carried at fair value measured on a recurring basis as of December 31, 2017 and December 31, 2016: December 31, 2017 Level 1 Level 2 Level 3 Total Assets Investment in securities $ 1,552,090 $ — $ — $ 1,552,090 Total assets at fair value $ 1,552,090 $ — $ — $ 1,552,090 December 31, 2016 Level 1 Level 2 Level 3 Total Assets Investment in securities $ 1,473,950 $ — $ — $ 1,473,950 Total assets at fair value $ 1,473,950 $ — $ — $ 1,473,950 There were no assets transferred from level 1 to level 2 as of December 31, 2017 or December 31, 2016. The Company did not have any assets or liabilities that are re-measured on a recurring basis using significant unobservable inputs as of December 31, 2017 or December 31, 2016. The fair values of financial instruments including cash and cash equivalents, restricted cash, accounts receivable, and accounts payable approximated their respective carrying values as of December 31, 2017 and 2016, respectively. The aggregate carrying value of the Company’s debt was $20,000,000 as of December 31, 2017 and 2016, respectively. The estimated fair value of the Company’s debt was $18,970,317 as of December 31, 2017 and 2016, respectively. These estimates were based on market interest rates for comparable obligations, general market conditions and maturity. The Company’s debt is classified as level 2 in the fair value hierarchy.

Notes Payable [Abstract]
Note Payable	8. NOTE PAYABLE On June 24, 2016, certain wholly owned subsidiaries (the “Secured Subsidiaries”) of the Company entered into a loan agreement (the “Loan Agreement”) borrowing the principal amount of $20 million pursuant to a promissory note (the “Promissory Note”). The Promissory Note bears an interest rate equal to 4.192% per annum (effective interest rate 4.40%) and is due to mature on July 1, 2036. Pursuant to a security agreement (the “Security Agreement”), the obligations under the Loan Agreement are secured by certain real estate assets owned by the Secured Subsidiaries. The Company entered into a non-recourse guaranty on June 24, 2016 (the “Guaranty,” and together with the Loan Agreement, the Promissory Note and the Security Agreement, the “Loan Documents”) to guarantee the payment to Lender of certain obligations of the Secured Subsidiaries under the Loan Agreement. The Loan Documents require the Secured Subsidiaries and the Company to comply with certain covenants, including, among others, a minimum net worth test and other customary covenants. The Lender may accelerate amounts outstanding under the Loan Documents upon the occurrence of an Event of Default (as defined in the Loan Agreement) including, but not limited to, the failure to pay amounts due or commencement of bankruptcy proceedings. The Company incurred loan procurement costs of $646,246 and such costs have been recorded net of the note payable on the consolidated balance sheet and are amortized as an adjustment to interest expense over the term of the loan. As of December 31, 2017 and 2016 the carrying value of the Company’s note payable is summarized as follows: Note Payable December 31, 2017 December 31, 2016 Principal balance outstanding $ 20,000,000 $ 20,000,000 Less: Loan procurement costs, net (582,595 ) (625,029 ) Total note payable, net $ 19,417,405 $ 19,374,971 As of December 31, 2017, the note payable was secured by certain of its self storage properties with an aggregate net book value of approximately $33.7 million.

Stockholders Rights Plan	12. STOCKHOLDER RIGHTS PLAN On January 28, 2016, the Company announced that the Board of Directors had adopted a stockholders rights plan (the “Rights Plan”). To implement the Rights Plan, the Board of Directors declared a dividend distribution of one right for each outstanding share of Company common stock, par value $.01 per share, to holders of record of the shares of common stock at the close of business on January 29, 2016. Each right entitled the registered holder to purchase from the Company one one-thousandth of a share of preferred stock, par value $.01 per share. The rights were distributed as a non-taxable dividend and were set to expire on January 29, 2026. The rights were evidenced by the underlying Company common stock, and no separate preferred stock purchase rights certificates had been distributed. The rights to acquire preferred stock were not immediately exercisable and would have become exercisable only if a person or group, other than Exempt Persons (as defined in the Rights Plan agreement), acquired or commenced a tender offer for 9.8% or more of the Company’s common stock. If a person or group, other than an Exempt Person, acquires or commences a tender offer for 9.8% or more of the Company’s common stock, each holder of a right, except the acquirer, would have been entitled, subject to the Company’s right to redeem or exchange the right, to exercise, at an exercise price of $12, the right to purchase one one-thousandth of a share of the Company’s newly created Series A Participating Preferred Stock, or the number of shares of Company common stock equal to the holder’s number of rights multiplied by the exercise price and divided by 50% of the market price of the Company’s common stock on the date of the occurrence of such an event. The Company’s Board of Directors could terminate the Rights Plan at any time or redeem the rights, for $0.01 per right, at any time before a person acquired 9.8% or more of the Company’s common stock. This Rights Plan replaced the Company’s stockholders rights plan dated November 25, 2015, which expired on its own terms on March 24, 2016. On October 20, 2017, the Company and American Stock Transfer & Trust Company, LLC, as rights agent (the “Rights Agent”), entered into an amendment (the “Rights Plan Amendment”) to the Company’s stockholders rights plan, dated as of January 29, 2016, between the Company and the Rights Agent (“Rights Plan”). The Rights Plan Amendment accelerated the expiration of the Company’s preferred share purchase rights under the Rights Plan from the Close of Business (as such term is defined in the Rights Plan) on January 29, 2026 to the Close of Business on October 20, 2017, and the Rights Plan was terminated at such time. At the time of the termination of the Rights Plan, all of the rights distributed to holders of the Company’s common stock pursuant to the Rights Plan expired.

SUBSEQUENT EVENTS On March 28, 2018, the Company filed with the SEC a Registration Statement on Form S-8 On March 29, 2018, the Company entered into an employment agreement with its Chief Executive Officer and President, Mark C. Winmill. The employment agreement has an initial term of three years and is subject to automatic one-year extensions thereafter, unless either party provides at least 90 days’ notice of non-renewal. The employment agreement provides for: • a monthly base salary of $26,416; • eligibility for an annual cash performance bonus based on the satisfaction of performance goals established by our Board of Directors or its Compensation Committee; and • participation in benefit plans applicable generally to executive officers. The employment agreement provides that, if Mr. Winmill’s employment is terminated by the Company without “cause” or by Mr. Winmill for “good reason” (each as defined in the employment agreement), or as a result of the Company’s notice of non-renewal of the employment term, Mr. Winmill will be entitled to the following severance payments and benefits, subject to the execution and non-revocation of a general release of claims: • accrued but unpaid base salary, bonus and other benefits earned and accrued but unpaid prior to the date of termination; • an amount equal to three times the sum of Mr. Winmill’s annual base salary plus the greater of the average annual bonus received by Mr. Winmill with respect to the two years prior to the year of termination and Mr. Winmill’s “target” annual bonus; and • continued health benefits (including for Mr. Winmill’s dependents) for twenty-four months following termination. In the event Mr. Winmill’s employment terminates by reason of his death or disability he or his estate shall receive: • accrued but unpaid base salary, bonus and other benefits earned and accrued but unpaid prior to the date of termination; • a prorated annual bonus for the year in which the termination occurs; and • continued health benefits (including for Mr. Winmill’s dependents) for twenty-four months following termination. The employment agreement contains standard confidentiality provisions, which apply indefinitely, and both non-competition and non-solicitation of employees and customers covenants, which apply during the term of employment and for a period of twelve months thereafter. On March 29, 2018, the Company approved restricted share awards under its 2017 Equity Incentive Plan (the “Plan”) to certain of its officers and employees in the aggregate amount of 73,155 shares, of which 15,025 shares are performance-based grants and the remainder of the shares are time-based grants. Mark Winmill, our Chief Executive Officer and President, and Thomas O’Malley, our Chief Financial Officer, received 32,125 and 13,900 shares, respectively. With respect to the grants made to Messrs. Winmill and O’Malley, 24,100 of the shares for Mr. Winmill and 10,400 of shares for Mr. O’Malley vest solely based on continued employment, with 6.25% of the shares eligible to vest on each three-month anniversary of the grant date. These restricted shares entitle the holder to dividends paid by the Company on shares of its common stock. Further, these time-based restricted share grants are front loaded and represent three years of grants; therefore, no additional time-based grants are currently expected be made to Messrs. Winmill and O'Malley in 2019 and 2020. The remaining 8,025 of the shares for Mr. Winmill and 3,500 of the shares for Mr. O'Malley vest based on continued employment and the achievement of certain AFFO and same store revenue growth (“SSRG”) goals by the Company during 2018. Between 0% and 200% of these shares will be earned based on achievement of the AFFO and SSRG goals in 2018, and the shares which are earned will remain subject to quarterly vesting during the remaining four-year time vesting period. Dividends paid by the Company prior to the determination of how many shares are earned will be retained by the Company and released only with respect to earned shares. If a Change in Control (as defined in the Plan) occurs during 2018, the number of shares earned will equal the greater of the number of shares granted and the number of shares which would have been earned based on the AFFO and SSRG through the date of the Change in Control. If following a Change in Control, a grantee is terminated by the Company without Cause or by the grantee with Good Reason (as each is defined in the Plan), all unvested restricted shares will fully vest.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2017
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation Upon deregistration as an investment company, the Company's status changed to an operating company from an investment company since it no longer met the assessment of an investment company under the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 946 (“ASC 946”). The Company discontinued applying the guidance in ASC 946 and began to account for the change in status prospectively by accounting for its investments in accordance with other U.S. generally accepted accounting principles (“GAAP”) topics as of the date of the change in status. The consolidated financial statements of the Company are presented on the accrual basis of accounting in accordance with GAAP and include the accounts of the Company and its wholly-owned subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of highly liquid investments, and may include money market fund shares, purchased with an original maturity of three months or less. The carrying amount reported on the balance sheet for cash and cash equivalents approximates fair value.
Restricted Cash	Restricted Cash Restricted cash is comprised of escrowed funds deposited with a bank relating to capital expenditures.
Income Taxes	Income Taxes The Company has elected to be treated as a REIT under the IRC. In order to maintain its qualification as a REIT, among other things, the Company is required to distribute at least 90% of its REIT taxable income to its stockholders and meet certain tests regarding the nature of its income and assets. As a REIT, the Company is not subject to federal income tax with respect to that portion of its income which meets certain criteria and is distributed annually to stockholders. The Company plans to continue to operate so that it meets the requirements for taxation as a REIT. Many of these requirements, however, are highly technical and complex. If the Company were to fail to meet these requirements, it would be subject to federal income tax. In managements opinion, the requirements to maintain these elections are being met. The Company is subject to certain state and local taxes. The Company recognizes the tax benefits of uncertain tax positions only where the position is “more likely than not” to be sustained assuming examination by tax authorities. The Company has reviewed its tax positions and has concluded that no liability for unrecognized tax benefits should be recorded related to uncertain tax positions taken on federal, state, and local income tax returns for open tax years (2014 – 2016), or is expected to be taken in the Company’s 2017 tax returns. Legislation, commonly known as the Tax Cuts and Jobs Act (“TCJA”) was signed into law on December 22, 2017. The TCJA makes significant changes to the U.S. federal income tax rates for taxation of individuals and corporations (including REITs), generally effective for taxable years beginning after December 31, 2017.
Investments in Securities	Investments in Securities Investments in equity securities that have readily determinable fair values are accounted for as available-for-sale. Available-for-sale securities are measured at fair value. Gains or losses from changes in the fair value of available-for-sale securities are recorded in accumulated other comprehensive income, until the investment is sold or otherwise disposed of, or until the investment is determined to be other-than-temporarily impaired, at which time the cumulative gain or loss previously reported in equity is included in income. The specific identification method is used to determine the realized gain or loss on investments sold or otherwise disposed. Fair value is determined using a valuation hierarchy generally by reference to an active trading market, using quoted closing or bid prices. Judgment is used to ascertain if a formerly active market has become inactive and in determining fair values when markets have become inactive. Prior to January 19, 2016, gains and losses from the changes in fair value of investment securities were recorded in the Statement of Operations.
Real Estate Assets	Real Estate Assets Real estate assets are carried at the appreciated value as of January 19, 2016, the effective date of the change in status to an operating company, less accumulated depreciation from that date. Purchases subsequent to the effective date of the change in status are carried at cost, less accumulated depreciation. Direct and allowable internal costs associated with the development, construction, renovation, and improvement of real estate assets are capitalized. Property taxes and other costs associated with development incurred during the construction period are capitalized. The construction period begins when expenditures for the real estate assets have been made and activities that are necessary to prepare the asset for its intended use are in progress. The construction period ends when the asset is substantially complete and ready for its intended use. We allocate the net acquisition cost of acquired operating self storage properties to the underlying land, buildings, identified intangible assets, and any noncontrolling interests that remain outstanding based upon their respective individual estimated fair values. Any difference between the net acquisition cost and the estimated fair value of the net tangible and intangible assets acquired is recorded as goodwill. Internal and external transaction costs associated with acquisitions or dispositions of real estate, as well as repairs and maintenance costs, are charged to expense as incurred. Major replacements and betterments that improve or extend the life of the asset are capitalized and depreciated over their estimated useful lives. Depreciation is computed using the straight-line method over the estimated useful lives of the buildings and improvements, which are generally between 5 and 39 years.
Accounts Payable and Accrued Expenses	Accounts Payable and Accrued Expenses Accounts payable and accrued expenses primarily consist of property tax accruals, unearned rental income, and trade payables. At December 31, 2017 and 2016, accounts payable and accrued expenses included a $900,000 contingent payment in connection with the purchase of a property made in 2016.
Retained Earnings	Retained Earnings Retained earnings includes an increase to fair value of the properties owned by the Company at the effective date of the change in status to a reporting company under the Exchange Act (see Footnote 3) and the accumulated net income or loss and accumulated distributions paid since inception.
Revenue and Expense Recognition	Revenue and Expense Recognition Revenues from stores, which are primarily composed of rental income earned pursuant to month-to-month leases for storage space, as well as associated late charges and administrative fees, are recognized as earned. Promotional discounts reduce rental income over the promotional period. Ancillary revenues from sales of merchandise and tenant insurance and other income are recognized when earned. The Company accrues for property tax expense based upon actual amounts billed and, in some circumstances, estimates and historical trends when bills or assessments have not been received from the taxing authorities or such bills and assessments are in dispute. Cost of operations and general and administrative expense are expensed as incurred.
Credit Risk	Credit Risk Financial assets that are exposed to credit risk consist primarily of cash and cash equivalents and certain portions of accounts receivable including rents receivable from our tenants. Cash and cash equivalents are on deposit with highly rated commercial banks.
Evaluation of Asset Impairment	Evaluation of Asset Impairment The Company evaluates its real estate assets, intangible assets consisting of in-place lease, and goodwill for impairment annually. If there are indicators of impairment and we determine that the asset is not recoverable from future undiscounted cash flows to be received through the asset’s remaining life (or, if earlier, the expected disposal date), we record an impairment charge to the extent the carrying amount exceeds the asset’s estimated fair value or net proceeds from expected disposal.
Stock-based Compensation	Stock-based Compensation On October 16, 2017, the Company’s stockholders approved the Company’s 2017 Equity Incentive Plan (the “Plan”). The Plan is designed to provide equity-based incentives to certain eligible persons, as defined in the Plan, in the form of options, share appreciation rights, restricted shares, restricted share units, dividend equivalent rights or other forms of equity-based compensation as determined in the discretion of the Board of Directors, the Compensation Committee of the Board of Directors, or other designee thereof. Awards granted are valued at fair value and any compensation expense is recognized over the service periods of each award. As of December 31, 2017, no awards have been granted under the Plan.
Use of Estimates	Use of Estimates The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the 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 materially differ from management’s estimates.
Recently Issued Accounting Standards	Recently Issued Accounting Standards In February 2017, as part of the new revenue standard, the FASB issued ASU No. 2017-05 – Other Income – Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Asset Derecognition Guidance, which focuses on recognizing gains and losses from the transfer of nonfinancial assets in contracts with non-customers. Specifically, the new guidance defines “in substance nonfinancial asset,” unifies guidance related to partial sales of nonfinancial assets, eliminates rules specifically addressing sales of real estate, removes exceptions to the financial asset derecognition model, and clarifies the accounting for contributions of nonfinancial assets to joint ventures. The new guidance is effective on January 1, 2018. Upon adoption, the Company expects that the majority of its sale transactions will be treated as dispositions of nonfinancial assets rather than dispositions of a business given the FASB’s recently revised definition of a business (see ASU No. 2017-01 below). Additionally, in partial sale transactions where the Company sells a controlling interest in real estate but retains a noncontrolling interest, the Company expects to now fully recognize a gain or loss on the fair value measurement of the retained interest as the new guidance eliminates the partial profit recognition model. In January 2017, the FASB issued ASU 2017-01 - Business Combinations (Topic 805): Clarifying the Definition of a Business, which changes the definition of a business to include an input and a substantive process that together significantly contribute to the ability to create outputs which are defined as the results of inputs and substantive processes that provide goods or services to customers, other revenue, or investment income. The standard is effective on January 1, 2018. Upon adoption of the new guidance, the Company expects that the majority of future property acquisitions will now be considered asset acquisitions, resulting in the capitalization of acquisition related costs incurred in connection with these transactions and the allocation of purchase price and acquisition related costs to the assets acquired based on their relative fair values. In November 2016, the FASB issued ASU No. 2016-18 - Statement of Cash Flows (Topic 230): Restricted Cash, which requires the statement of cash flows to explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. The new guidance also requires entities to reconcile such total to amounts on the balance sheet and disclose the nature of the restrictions. The standard is effective on January 1, 2018. The standard requires the use of the retrospective transition method. The adoption of this guidance will not have a material impact on the Company’s consolidated financial statements as the update relates to financial statement presentation and disclosures. In August 2016, the FASB issued ASU No. 2016-15 - Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. The eight items that the ASU provides classification guidance on include (1) debt prepayment and extinguishment costs, (2) settlement of zero-coupon debt instruments, (3) contingent consideration payments made after a business combination, (4) proceeds from the settlement of insurance claims, (5) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies, (6) distributions received from equity method investments, (7) beneficial interests in securitization transactions, and (8) separately identifiable cash flows and application of the predominance principle. The standard became effective on January 1, 2018. The standard requires the use of the retrospective transition method. The adoption of this guidance will not have a material impact on the Company’s consolidated financial statements as the update relates to financial statement presentation and disclosures. In March 2016, the FASB issued ASU No. 2016-09, Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which is intended to simplify various aspects related to how share-based payments are accounted for and presented in the financial statements. The new guidance allows for entities to make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. In addition, the guidance allows employers to withhold shares to satisfy minimum statutory tax withholding requirements up to the employees’ maximum individual tax rate without causing the award to be classified as a liability. The guidance also stipulates that cash paid by an employer to a taxing authority when directly withholding shares for tax-withholding purposes should be classified as a financing activity on the statement of cash flows. The standard became effective on January 1, 2017. The adoption of this guidance did not have an impact on the Company’s consolidated financial position or results of operations. In February 2016, the FASB issued ASU No. 2016-02 - Leases (Topic 842), which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either financing or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. The new standard requires 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. The standard is effective on January 1, 2019, however early adoption is permitted. The Company does not believe this standard will have a material impact on operating results of financial condition, because all lease revenues are derived from month to month self storage leases and the Company does not incur a material amount of lease expense. In January 2016, the FASB issued ASU 2016-01, Financial Instruments – Overall (Subtopic 825-10). The updated accounting guidance, among other things, requires that all nonconsolidated equity investments, except those accounted for under the equity method, be measured at fair value and that the changes in fair value be recognized in net income. The updated guidance is effective for the Company as of January 1, 2018. With certain exceptions, the updated accounting guidance requires a cumulative effect adjustment to beginning retained earnings in the year the guidance is adopted. If we had adopted the provisions of the updated guidance as of January 1, 2017 for our equity investments classified as available-for-sale securities, net income attributable to such securities would have increased by approximately $78,000 in 2017. In May 2014, the FASB issued ASU No. 2014-09 - Revenue from Contracts with Customers (Topic 606), 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 new guidance outlines a five-step process for customer contract revenue recognition that focuses on transfer of control as opposed to transfer of risk and rewards. The new guidance also requires enhanced disclosures regarding the nature, amount, timing, and uncertainty of revenues and cash flows from contracts with customers. In May 2016, the FASB issued ASU 2016-12 - Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, which amends ASU 2014-09 and is intended to address implementation issues that were raised by stakeholders. ASU 2016-12 provides practical expedients on collectability, noncash consideration, presentation of sales tax and contract modifications and completed contracts in transition. Both standards became effective on January 1, 2018. The standards will not have a material impact on the Company’s consolidated statements of financial position or results of operations primarily because the majority of its revenue is derived from lease contracts, which are excluded from the scope of the new guidance. The Company’s insurance fee revenue, and merchandise sale revenue are included in the scope of the new guidance, however, the Company identified similar performance obligations under this standard as compared with deliverables and separate units of account identified under its previous revenue recognition methodology. Accordingly, revenue recognized under the new guidance will not differ materially from revenue recognized under previous guidance and there will be no material prior year impact.
