Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization and Description of Business	1. ORGANIZATION AND DESCRIPTION OF BUSINESS: GTJ REIT, Inc. (the “Company” or “GTJ REIT”) was incorporated on June 26, 2006, under the Maryland General Corporation Law. The Company is focused primarily on the acquisition, ownership, management, and operation of commercial real estate located in New York, New Jersey, Connecticut and Delaware. The Company has elected to be treated as a real estate investment trust, or REIT, under the Internal Revenue Code of 1986, as amended (the “Code”). The Company elected December 31 as its fiscal year end. Under the REIT operating structure, the Company is permitted to deduct the dividends paid to its stockholders when determining its taxable income. Assuming dividends equal or exceed the Company’s taxable income, the Company generally will not be required to pay federal corporate income taxes on such income. On January 17, 2013, the Company closed on a transaction with Wu/Lighthouse Portfolio, LLC, in which a limited partnership (the “Operating Partnership”) owned and controlled by the Company, acquired all outstanding ownership interests of a portfolio consisting of 25 commercial properties (the “Acquired Properties”) located in New York, New Jersey and Connecticut, in exchange for 33.29% of the outstanding limited partnership interest in the Operating Partnership. The outstanding limited partnership interest in the Operating Partnership exchanged for the Acquired Properties was increased to 33.78% due to post-closing adjustments, and to 34.67% due to redemptions of certain shares of GTJ REIT common stock. The acquisition was recorded as a business combination and, accordingly, the purchase price was allocated to the assets acquired and liabilities assumed at fair value. At June 30, 2021, subject to certain anti-dilutive and other provisions contained in the governing agreements, the limited partnership interests in the Operating Partnership may be converted in the aggregate, into approximately 1.9 million shares of the Company’s common stock and approximately 5.4 million shares of the Company’s Series B preferred stock. As of June 30, 2021, the Operating Partnership owned and operated 48 properties consisting of approximately 5.9 million square feet of primarily industrial space on approximately 389 acres of land in New York, New Jersey, Connecticut and Delaware. The Operating Partnership also owns, through a joint venture, a 50% interest in a recently constructed state-of-the-art industrial building in Piscataway, New Jersey. On March 11, 2020, the World Health Organization declared COVID-19, a respiratory illness caused by the novel coronavirus, a pandemic, and on March 13, 2020, the United States declared a national emergency with respect to COVID-19. The COVID-19 pandemic has caused state and local governments within New York, New Jersey, Connecticut, Delaware and elsewhere to institute quarantines, “shelter in place” rules and restrictions on travel, the types of business that may continue to operate, and/or the types of construction projects that may continue. Although many of these restrictions have been lifted, the Company cannot predict whether and to what extent restrictions will be reinstated, whether additional restrictions will be implemented or when restrictions currently in place will expire, in particular due to the impact of variants of COVID-19, such as the Delta variant. The Company continues to monitor its operations and government recommendations and has made modifications to its normal operations, including having its employees work remotely. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was signed into law to provide widespread emergency relief for the economy and to provide aid to corporations. The CARES Act, among other things, includes provisions relating to refundable payroll tax credits, deferment of employer side social security payments, net operating loss carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations, increased limitations on qualified charitable contributions, and technical corrections to tax depreciation methods for qualified improvement property. The effects of the COVID-19 pandemic did not significantly impact the Company’s results of operations, financial condition and cash flows for the six months ended June 30, 2021. However, the COVID-19 pandemic may materially affect the Company’s financial condition and results of operations going forward, including but not limited to, its real estate rental revenues. The Company derives revenues primarily from rents and reimbursement payments received from tenants under leases at the Company’s properties. The Company’s operating results therefore depend materially on the ability of its tenants to make required rental payments. Given the Company’s concentration in the Northeast United States, its entire portfolio could remain subject to various governmental restrictions for the foreseeable future. The extent to which the COVID-19 pandemic impacts the businesses of the Company’s tenants, and the Company’s results of operations, financial condition and cash flows will depend on future developments which are highly uncertain and cannot be predicted with confidence, including the scope, severity and duration of the pandemic, the timing and effectiveness of the ongoing rollout of currently available vaccines, the spread of potentially more contagious and/or virulent forms of the virus, the actions taken to contain the pandemic or mitigate its impact, and the direct and indirect economic effects of the pandemic and such containment measures, among others. While the extent of the pandemic and its impact on the Company and its tenants is uncertain, a prolonged crisis could result in continued disruptions in the credit and financial markets, continued fluctuations in unemployment rates, and an overall worsening of global and U.S. economic conditions. The COVID-19 pandemic is negatively impacting almost every industry directly or indirectly, including industries in which the Company and its tenants operate. The factors described above, as well as additional factors that the Company may not currently be aware of, could materially negatively impact the Company’s ability to collect rent and could lead to termination of leases by tenants, tenant bankruptcies, decreases in demand for properties, difficulties in accessing capital, impairment of the Company’s long-lived assets and other impacts that could materially and adversely affect the Company’s business, results of operations, financial condition and ability to pay distributions to stockholders. A prolonged pandemic could have a material adverse impact on the financial results and business operations of the Company. As of June 30, 2021, the Company agreed upon certain rent relief requests, most often in the form of rent deferral requests, as a result of COVID-19. Not all tenant requests resulted in amended agreements, nor did the Company forego its contractual rights under its lease agreements. Tenants that were granted rent relief requests are in compliance with their rent deferral agreements. These rent relief requests from the Company’s tenants did not have a material impact on the Company’s results of operations, financial condition or cash flows as of June 30, 2021. The rent relief requests resulted in the total payments required by the modified contract being substantially the same or less than the total payments required by the original contract. Therefore, the Company has elected to account for lease concessions related to the effects of the COVID-19 pandemic consistent with how those concessions would be accounted for under lease accounting pronouncements as though enforceable rights and obligations for the concessions existed, regardless of whether those enforceable rights and obligations for the concessions explicitly exist in the contract.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: Basis of Presentation: The accompanying unaudited condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and include the financial statements of the Company, its wholly owned subsidiaries, and the Operating Partnership, as the Company makes all operating and financial decisions for (i.e., exercises control over) the Operating Partnership. All material intercompany transactions have been eliminated. The ownership interests of the other investors in the Operating Partnership are presented as non-controlling interests. The accompanying unaudited condensed consolidated interim financial information has been prepared according to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted in accordance with such rules and regulations. The Company’s management believes that the disclosures presented in these unaudited condensed consolidated financial statements are adequate to make the information presented not misleading. In management’s opinion, all adjustments and eliminations, consisting only of normal recurring adjustments, necessary to present fairly the financial position and results of operations for the reported periods have been included. The results of operations for such interim periods are not necessarily indicative of the results for the full year. The accompanying unaudited condensed consolidated interim financial information should be read in conjunction with the Company’s December 31, 2020, audited consolidated financial statements, as previously filed with the SEC on Form 10-K on March 25, 2021. The Company has determined that redemptions of Company shares result in a reallocation between the Operating Partnership’s non-controlling interest (“OP NCI”) and Additional Paid-in-Capital (“APIC”). During the six months ended June 30, 2021, there were no redemptions of Company shares, and therefore, no reallocation was required. Use of Estimates: The preparation of the Company’s condensed consolidated financial statements in conformity with GAAP requires management to make estimates, judgments, and assumptions that affect the reported amounts of assets and liabilities, and related disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amount of revenues and expenses during the reporting period. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. All of these estimates reflect management’s best judgment about current economic and market conditions and their effects based on information available as of the date of these condensed consolidated financial statements. If such conditions persist longer or deteriorate further than expected, it is reasonably possible that the judgments and estimates could change, which may result in impairments of certain assets. Significant estimates include the useful lives of long-lived assets including property, equipment and intangible assets, impairment of assets, collectability of receivables, contingencies, stock-based compensation, and fair value of assets and liabilities acquired in business combinations. Reclassification: None of the prior year amounts have been reclassified for consistency with the current year presentation. Real Estate: Real estate assets are stated at cost, less accumulated depreciation and amortization. All costs related to the improvement or replacement of real estate properties, including interest expense on development properties, are capitalized. Acquisition related costs are capitalized for asset acquisitions. Additions, renovations, and improvements that enhance and/or extend the useful life of a property are also capitalized. Expenditures for ordinary maintenance, repairs, and improvements that do not materially prolong the normal useful life of an asset are charged to operations as incurred. The Company capitalizes all direct costs of real estate under development until the end of the development period. In addition, the Company capitalizes the indirect cost of insurance and real estate taxes allocable to real estate under development during the development period. The Company also capitalizes interest using the avoided cost method for real estate under development during the development period. The Company will cease the capitalization of these costs when development activities are substantially completed and the property is available for occupancy by tenants, but no later than one year from the completion of major construction activity at which time the property is placed in service and depreciation commences. If the Company suspends substantially all activities related to development of a qualifying asset, the Company will cease capitalization of these costs until activities are resumed. The Company had no real estate under development as of June 30, 2021 and December 31, 2020. Upon the acquisition of real estate properties, the relative fair value of the real estate purchased is allocated to the acquired tangible assets (generally consisting of land, buildings and building improvements, and tenant improvements) and identified intangible assets and liabilities (generally consisting of above-market and below-market leases and the origination value of in-place leases) on a relative fair value basis in accordance with GAAP. The Company utilizes methods similar to those used by independent appraisers in estimating the fair value of acquired assets and liabilities. The fair value of the tangible assets of an acquired property considers the value of the property “as-if-vacant.” In allocating the purchase price to identified intangible assets and liabilities of an acquired property, the value of above-market and below-market leases is estimated based on the differences between contractual rentals and estimated market rents over the applicable lease term discounted back to the date of acquisition utilizing a discount rate adjusted for the credit risk associated with the respective tenants. Fixed-rate renewal options have been included in the calculation of the fair value of acquired leases where applicable. The aggregate value of in-place leases is measured based on the avoided costs associated with lack of revenue over a market-oriented lease-up period, the avoided leasing commissions, and other avoided costs common in similar leasing transactions. Mortgage notes payable assumed in connection with acquisitions are recorded at their fair value using current market interest rates for similar debt at the time of acquisitions. The capitalized above-market lease values are amortized as a reduction of rental revenue over the remaining term of the respective leases and the capitalized below-market lease values are amortized as an increase to rental revenue over the remaining term of the respective leases. The value of in-place leases is based on the Company’s evaluation of the specific characteristics of each tenant’s lease. Factors considered include estimates of carrying costs during expected lease-up periods, current market conditions, and costs to execute similar leases. The values of in-place leases are amortized over the remaining term of the respective leases. If a tenant terminates its lease prior to its contractual expiration date, any unamortized balance of the related intangible assets or liabilities is recorded as income or expense in the period. The total net impact to rental revenues due to the amortization of above and below-market leases was a net increase of approximately $0.1 million and $0.3 million for the six months ended June 30, 2021 and June 30, 2020, respectively. As of June 30, 2021, above-market and in-place leases of approximately $0.4 million and $6.5 million (net of accumulated amortization), respectively, are included in acquired lease intangible assets, net in the accompanying condensed consolidated balance sheets. As of December 31, 2020, above-market and in-place leases of approximately $0.6 million and $7.3 million (net of accumulated amortization), respectively, are included in acquired lease intangible assets, net in the accompanying condensed consolidated balance sheets. As of June 30, 2021, and December 31, 2020, approximately $2.9 million and $3.2 million (net of accumulated amortization), respectively, relating to below-market leases are included in acquired lease intangible liabilities, net in the accompanying condensed consolidated balance sheets. The following table presents the projected impact for the remainder of 2021, the next five years and thereafter related to the net increase to rental revenue from the amortization of the acquired above-market and below-market lease intangibles and the increase to amortization expense of the in-place lease intangibles for properties owned at June 30, 2021 (in thousands): Net increase to Increase to rental revenues amortization expense Remainder of 2021 $ 294 $ 669 2022 611 1,300 2023 635 1,189 2024 498 904 2025 147 733 2026 71 603 Thereafter 258 1,106 $ 2,514 $ 6,504 Investment in Unconsolidated Affiliate: The Company has an investment in an entity that has been accounted for under the equity method of accounting. The equity method of accounting is used when an investor has influence, but not control, over the investee. The Company records its share of the profits and losses of the investee in the period when theses profits and losses are also reflected in the accounts of the investee. On February 28, 2018, the Company purchased a 50% interest in Two CPS Developers LLC (the “Investee”) for $5.25 million. The Company has the ability to exercise significant influence over the Investee, does not have a controlling interest in the Investee, and the Investee is not a variable interest entity. Therefore, the Company accounts for this investment under the equity method of accounting. The Company recorded income of approximately $0.1 million from this investment for the six months ended June 30, 2021 and 2020, respectively. The total assets and liabilities of the Company’s investment in unconsolidated affiliate as of June 30, 2021 were $17.6 million and $10.0 million, respectively. Total revenues and expenses of the Company’s investment in unconsolidated affiliate for the six months ended June 30, 2021 were $0.8 million and $0.7 million, respectively. The total assets and liabilities of the Company’s investment in unconsolidated affiliate as of December 31, 2020 were $17.9 million and $10.0 million, respectively. Total revenues and expenses of the Company’s investment in unconsolidated affiliate for the six months ended June 30, 2020 were $0.8 million and $0.7 million, respectively. Depreciation and Amortization: The Company uses the straight-line method for depreciation and amortization. Properties and property improvements are depreciated over their estimated useful lives, which range from 5 to 40 years. Furniture, fixtures, and equipment are depreciated over estimated useful lives that range from 5 to 10 years. Tenant improvements are amortized over the shorter of the remaining non-cancellable term of the related leases or their useful lives. Asset Impairment: Management reviews each real estate investment for impairment whenever events or circumstances indicate that the carrying value of a real estate investment may not be recoverable. The review of recoverability is based on an estimate of the undiscounted future cash flows that are expected to result from the real estate investment’s use and eventual disposition. Such cash flow analyses consider factors such as expected future operating income, trends and prospects, as well as the effects of leasing demand, competition and other factors. If an impairment event exists due to the projected inability to recover the carrying value of a real estate investment, an impairment loss is recorded to the extent that the carrying value exceeds estimated fair value. Management is required to make subjective assessments as to whether there are impairments in the value of the Company’s real estate holdings. These assessments could have a direct impact on net income, because an impairment loss is recognized in the period the assessment is made. Management has determined that there was no impairment related to its long-lived assets at June 30, 2021 or December 31, 2020. Deferred Charges: Deferred charges consist principally of leasing commissions, which are amortized over the life of the related tenant leases, and financing costs, relating to the Company’s secured revolving credit facility, which are amortized over the terms of the respective debt agreements. These deferred charges are included in other assets on the consolidated balance sheets. If leases or loans are terminated, the unamortized charges are expensed. Reportable Segments: The Company operates in one reportable segment, commercial real estate. Revenue Recognition: Rental income includes the base rent that each tenant is required to pay in accordance with the terms of their respective leases reported on a straight-line basis over the term of the lease. Rental income related to tenants where the collectability of lease payments is not deemed probable will be recorded on a cash basis. If the Company determines that the collectability of a tenant’s lease payments is not probable, then the write-off of the entire tenant receivable, including straight-line rent receivable, is presented as a reduction of revenue rather than an operating expense on the statement of operations. Some of the leases provide for additional contingent rental revenue in the form of increases based on the consumer price index, subject to certain maximums and minimums. Substantially all of the Company’s properties are subject to long-term net leases under which the tenant is typically responsible to pay for its pro rata share of real estate taxes, insurance, and ordinary maintenance and repairs for the property. Property operating expense recoveries from tenants of common area maintenance, real estate taxes, and other recoverable costs are included in revenues in the period that the related expenses are incurred. Future minimum contractual lease payments to be received by the Company (without taking into account straight-line rent, amortization of intangibles and tenant reimbursements) as of June 30, 2021, under operating leases for the remainder of 2021, the next five years, and thereafter are as follows (in thousands): Remainder of 2021 $ 25,439 2022 50,217 2023 45,734 2024 39,665 2025 37,093 2026 34,553 Thereafter 52,093 Total $ 284,794 Lease Accounting: The Company has made an accounting policy election to account for lease concessions related to the effects of COVID-19 consistent with how those concessions would be accounted for under Topic 842, which is as though the enforceable rights and obligations for those concessions existed regardless of whether those enforceable rights and obligations for the concessions explicitly exist in the contract. The Company elected to utilize the practical expedient provided by ASU 2018-11 related to the separation of lease and non-lease components and as a result, revenues related to leases are reported on one line in the presentation within the consolidated statement of operations. As lessee, the Company elected to utilize the practical expedient in the implementation of ASU 2016-02 related to not separating non-lease components from the associated lease component. As lessee, the Company is a party to an office lease which expired on December 31, 2020. The Company will continue to occupy the premises on a month-to-month basis at a current base rent of $24,000. The Company includes right-of-use assets in other assets and right-of-use liabilities as other liabilities on its consolidated balance sheet. There are no right-of-use assets or right-of-use liabilities included in other assets or other liabilities as of June 30, 2021 and December 31, 2020, respectively. The Company elected not to evaluate whether certain sales taxes and other similar taxes are lessor costs or lessee costs. Instead, these costs will be accounted for as if they are lessee costs. Consequently, the Company excludes from the consideration in the contract and from variable payments not included in the consideration in the contract all collections from lessees of taxes within the scope of the election and provides certain disclosures. The accounting policy election includes sales, use, value added, and some excise taxes but excludes real estate taxes. Earnings Per Share Information: The Company presents both basic and diluted earnings per share. Basic earnings per share excludes dilution and is computed by dividing net income attributable to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock, where such exercise or conversion would result in a lower per share amount. Restricted stock and stock options were included in the computation of diluted earnings per share. Cash and Cash Equivalents: The Company considers all highly liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents. Restricted Cash: Restricted cash includes reserves used to pay real estate taxes, leasing costs and capital improvements. Fair Value Measurement: The Company determines fair value in accordance with Accounting Standards Codification (“ASC”) Topic 820, “Fair Value Measurement.” This standard defines fair value, provides guidance for measuring fair value and requires certain disclosures. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Where available, fair value is based on observable market prices or parameters or derived from such prices or parameters. Where observable prices or inputs are not available, valuation models are applied. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the instruments or market and the instruments’ complexity. Assets and liabilities disclosed at fair values are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels, which are defined by ASC 820-10-35, are directly related to the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities. Determining which category an asset or liability falls within the hierarchy requires significant judgment, and the Company evaluates its hierarchy disclosures each quarter. The three-tier fair value hierarchy is as follows: Level 1 — Valuations based on quoted prices for identical assets and liabilities in active markets. Level 2 — Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3 — Valuations based on unobservable inputs reflecting management’s own assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment. Income Taxes: The Company is organized and conducts its operations to qualify as a REIT for federal income tax purposes. Accordingly, the Company is generally not subject to federal income taxation on the portion of its distributable income that qualifies as REIT taxable income, to the extent that it distributes at least 90% of its REIT taxable income to its stockholders and complies with certain other requirements as defined in the Code. The Company also participates in certain activities conducted by entities which elected to be treated as taxable subsidiaries under the Code. As such, the Company is subject to federal, state, and local taxes on the income from these activities. The Company accounts for income taxes under the asset and liability method as required by the provisions of ASC 740-10-30. Under this method, deferred tax assets and liabilities are established based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company provides a valuation allowance for deferred tax assets for which it does not consider realization of such assets to be more likely than not. ASC 740-10-65 addresses the determination of whether tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. Under ASC 740-10-65, the Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position should be measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. ASC 740-10-65 also provides guidance on de-recognition, classification, interest and penalties on income taxes, and accounting in interim periods and requires increased disclosures. As of June 30, 2021, and December 31, 2020, the Company had determined that no liabilities are required in connection with uncertain tax positions. As of June 30, 2021, the Company’s tax returns for the prior three years are subject to review by the Internal Revenue Service. Any interest and penalties would be expensed as incurred. Concentrations of Credit Risk: Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents, which from time-to-time exceed the federal depository insurance coverage. Beginning January 1, 2013, all interest and noninterest bearing transaction accounts deposited at an insured depository institution are insured by the Federal Deposit Insurance Corporation up to the standard maximum deposit amount of $250,000. Management believes that the Company is not exposed to any significant credit risk due to the credit worthiness of the financial institutions. For the six months ended June 30, 2021, rental income of $4.8 million derived from five leases with the City of New York represents approximately 15% of the Company’s rental income. Stock-Based Compensation: The Company has a stock-based compensation plan which is described below in Note 5. The Company accounts for stock-based compensation in accordance with ASC Topic 718, “Compensation – Stock Compensation,” which establishes accounting for stock-based awards exchanged for employee services. Under the provisions of ASC Topic 718, share-based compensation cost is measured at the grant date or service-inception date (if it precedes the grant date), based on the fair value of the award. Share-based compensation is expensed at the grant date (for awards or portion of awards that vested immediately), or ratably over the respective vesting periods, determined from the start of the grant date or service-inception date through the date of vesting. Recently Issued Accounting Pronouncements: In January 2021, the Financial Accounting Standards Board (“FASB”) issued ASU 2021-01, “Reference Rate Reform (Topic 848),” which modifies ASC 848 (ASU 2020-04 discussed below), which was intended to provide relief related to “contracts and transactions that reference LIBOR or a reference rate that is expected to be discontinued as a result of reference rate reform.” ASU 2021-01 expands the scope of ASC 848 to include all affected derivatives and give reporting entities the ability to apply certain aspects of the contract modification and hedge accounting expedients to derivative contracts affected by the discounting transition. ASU 2021-01 also adds implementation guidance to clarify which optional expedients in ASC 848 may be applied to derivative instruments that do not reference LIBOR or a reference rate that is expected to be discontinued, but that are being modified as a result of the discounting transition. The Company does not have any derivative transactions to which this ASU applied. As a result, the implementation of this guidance is not expected to have a material effect on the Company’s consolidated financial statements. In March 2020, the FASB issued ASU No. 2020-04, “Reference Rate Reform (Topic 848) – Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” The new guidance provides optional expedients and exceptions for applying generally accepted accounting principles when accounting for contract modifications, hedging relationships and other transactions impacted by rate reform, subject to meeting certain criteria. ASU 2020-04 is effective as of March 12, 2020 through December 31, 2022. The Company had no transactions to which the ASU was applied since adoption and we are considering the impact of reference rate reform on our consolidated financial statements.

Line Of Credit Facility [Abstract]
Secured Revolving Credit Facility	4 . : On December 2, 2015, the Operating Partnership entered into a Credit Agreement (the “Key Bank Credit Agreement”) with Keybank National Association and Keybanc Capital Markets Inc., as lead arranger (collectively, “Key Bank”). The Key Bank Credit Agreement contemplated a $50.0 million revolving line of credit facility, with an initial term of two years, with a one-year Loans drawn down by the Operating Partnership under the facility will need to specify, at the Operating Partnership’s option, whether they are base-rate loans or LIBOR-rate loans. The base-rate loans initially bore a base rate of interest calculated as the sum of (i) the greater of: (a) the fluctuating annual rate of interest announced from time to time by Key Bank as its “prime rate,” (b) 0.5% above the rate announced by the Federal Reserve Bank of Cleveland (or Federal Funds Effective Rate), or (c) LIBOR plus 100 basis points (bps); plus (ii) 200 to 250 bps, depending on the overall leverage of the properties. The LIBOR-rate loans initially bore interest at a rate of LIBOR rate plus 300 to 350 bps, depending upon the overall leverage of the properties. Each revolving credit loan under the facility will be evidenced by separate promissory note(s). The Operating Partnership agreed to pay to Key Bank an unused facility fee in the amount calculated as 0.30% for usage less than 50% and 0.20% for usage 50% or greater, calculated as a per diem rate, multiplied by the excess of the total commitment over the outstanding principal amount of the loans under the facility at the time of the calculation. Key Bank has the right to reduce the amount of loan commitments under the facility provided that, among other things, they give an advance written notice of such reductions and that in no event the total commitment under the facility is less than $25.0 million. The Operating Partnership may at its option convert any of the revolving credit loans into a revolving credit loan of another type which loan will then bear interest as a base-rate loan or a LIBOR-rate loan, subject to certain conversion conditions. In addition, Key Bank also agreed to extend, from time to time, as the Operating Partnership may request, upon an advance written notice, swing loans in the total amount not to exceed $5.0 million. Such loans, if and when extended, will also be evidenced by separate promissory note(s). Due to the revolving nature of the facility, amounts prepaid under the facility may be borrowed again. The Key Bank Credit Agreement contemplates (i) mandatory prepayments by the Operating Partnership of any borrowings under the facility in excess of the total allowable commitment, among other events, and (ii) optional prepayments, without any penalty or premium, in whole or in part, subject to payments of any amounts due associated with the prepayment of LIBOR rate contracts. The Operating Partnership’s obligations under the facility are secured by a first priority lien and security interest to be held by the agents for Key Bank, in certain of the property, rights and interests of the Operating Partnership, the Guarantors (as defined below) and their subsidiaries now existing and as may be acquired (collectively, the “Collateral”). GTJ REIT and each party to the Guaranty are collectively referred to as the “Guarantors.” The parties to the Key Bank Credit Agreement also entered into several side agreements, including, the Joinder Agreements, the Assignment of Interests, the Acknowledgments, the Mortgages, the Guaranty, and other agreements and instruments to facilitate the transactions contemplated under the Key Bank Credit Agreement. Such agreements contain terms and provisions that are customary for instruments of this nature. The Operating Partnership’s continuing ability to borrow under the facility will be subject to its ongoing compliance with various affirmative and negative covenants, including, among others, with respect to liquidity, minimum occupancy, total indebtedness and minimum net worth. The Key Bank Credit Agreement contains events of default and remedies customary for loan transactions of this sort including, among others, those related to a default in the payment of principal or interest, a material inaccuracy of a representation or warranty, and a default with regard to performance of certain covenants. The Key Bank Credit Agreement also includes customary events of default (in certain cases subject to customary cure), in the event of which, amounts outstanding under the facility may be accelerated. The Key Bank Credit Agreement includes customary representations and warranties of the Operating Partnership which must continue to be true and correct in all material respects as a condition to future draws. On July 27, 2017, the maturity date under the Key Bank Credit Agreement was extended from December 1, 2017 to February 28, 2018, with an additional extension option to June 30, 2019, subject to the satisfaction of certain conditions. On February 27, 2018, the Operating Partnership exercised its option to extend the maturity date of the secured revolving line of credit facility with Key Bank to June 30, 2019. On July 31, 2018, the maturity date of the secured revolving credit facility with Key Bank was extended from June 30, 2019 to June 30, 2020 and the applicable margin for LIBOR-rate loans and base-rate loans applicable to the secured revolving credit facility with Key Bank was reduced by 50 bps. The base rate loans bore a base rate of interest calculated as the sum of (i) the greater of: (a) the fluctuating annual rate of interest announced from time to time by Key Bank as its “prime rate,” (b) 50 bps above the rate announced by the Federal Reserve Bank of Cleveland (or Federal Funds Effective Rate), or (c) LIBOR plus 100 bps; plus (ii) 150 to 200 bps, depending on the overall leverage of the properties . The LIBOR rate loans bore interest at a rate of LIBOR plus 250 to 300 bps, depending upon the overall leverage of the properties . On September 11, 2019, the Operating Partnership entered into an amendment to the Key Bank Credit Agreement which reduced the applicable margin for LIBOR-rate loans and base-rate loans by 10 bps. The base-rate loans will bear a base rate of interest calculated as the sum of (i) the greater of: (a) the fluctuating annual rate of interest announced from time to time by Key Bank as its “prime rate,” (b) 50 bps above the rate announced by the Federal Reserve Bank of Cleveland (or Federal Funds Effective Rate), or (c) LIBOR plus 100 bps; plus (ii) 140 to 190 bps, depending on the overall leverage of the properties. The LIBOR-rate loans will bear interest at a rate of LIBOR plus 240 to 290 bps, depending upon the overall leverage of the properties. In addition, the maturity date of the secured revolving credit facility with Key Bank was extended from June 30, 2020 to June 30, 2022. On March 27, 2020, the Operating Partnership drew down $10.0 million under the secured revolving credit facility with Key Bank. The Operating Partnership increased its borrowings under the secured revolving credit facility with Key Bank as a precautionary measure in order to increase liquidity and preserve financial flexibility in light of current uncertainty resulting from the COVID-19 pandemic. The contemplated uses of proceeds under the Key Bank Credit Agreement include, among others, repayment of indebtedness, funding of acquisitions, development and capital improvements, as well as working capital expenditures.

Earnings Per Share [Abstract]
Earnings per Share	6. EARNINGS PER SHARE: In accordance with ASC Topic 260 “Earnings Per Share,” basic earnings per common share (“Basic EPS”) is computed by dividing the net income attributable to common stockholders by the weighted-average number of common shares outstanding. Diluted earnings per common share (“Diluted EPS”) is computed by dividing net income attributable to common stockholders by the weighted average number of common shares and dilutive common share equivalents and convertible securities then outstanding. There were 25,849 and 37,448 common share equivalents in the six months ended June 30, 2021 and 2020, respectively, presented in Diluted EPS. The following table sets forth the computation of basic and diluted earnings per share information for the three and six months ended June 30, 2021 and 2020 (in thousands, except share and per share data): Three Months Ended Six Months Ended June 30, June 30, 2021 2020 2021 2020 Numerator: Net income attributable to common stockholders $ 1,130 $ 905 $ 2,857 $ 2,253 Denominator: Weighted average common shares outstanding – basic 13,661,058 13,564,370 13,644,233 13,551,113 Weighted average common shares outstanding – diluted 13,686,907 13,601,818 13,670,082 13,588,561 Basic and Diluted Per Share Information: Net income per share – basic and diluted $ 0.08 $ 0.07 $ 0.21 $ 0.17

Related Party Transactions [Abstract]
Related Party Transactions	7. RELATED PARTY TRANSACTIONS: Paul Cooper, the Chairman and Chief Executive Officer of the Company, and Louis Sheinker, the President, Secretary and Chief Operating Officer of the Company, each hold minority ownership interests in a real estate brokerage firm in which they do not engage in management activities, The Rochlin Organization. The firm acted as the exclusive broker for one of the Company’s properties. In 2013, the firm introduced a new tenant to the property, resulting in the execution of a lease agreement and a subsequent lease modification and the firm earning brokerage commissions. In subsequent years, the tenant has expanded square footage and exercised renewal options, resulting in the firm earning additional brokerage commissions. In March 2018, the tenant exercised its option to renew its lease for the premises resulting in approximately $107,000 of brokerage commissions on the additional lease modification value of $3,600,000. In November 2018, the tenant concluded negotiations to expand the premises by an additional 30,000 square feet which resulted in approximately $40,000 of brokerage commissions on the additional lease modification value of $670,000. In February 2020, the tenant exercised its option to renew its lease for the premises resulting in approximately $135,000 of brokerage commissions on the additional future lease payments of approximately $4,500,000. In July 2020, the firm introduced a new tenant to the property, resulting in the execution of a lease agreement and the firm earning a brokerage commission of approximately $406,000 on future lease payments of approximately $21,000,000. The Company’s executive and administrative offices, located at 60 Hempstead Avenue, West Hempstead, New York, are being leased from Lighthouse Sixty, L.P., a partnership of which Paul Cooper and Louis Sheinker are managing members of the general partner. The lease agreement expired in 2020. The Company will continue to occupy the premises on a month-to-month basis at a current base rent of approximately $24,000 On November 4, 2014, the Company invested $1.8 million for a limited partnership interest in Garden 1101 Stewart, L.P. (“Garden 1101”). Garden 1101 was formed for the purposes of acquiring an office building in Garden City, NY that was converted to a medical office building. The general partner of Garden 1101 is partially owned by Paul Cooper and Louis Sheinker. The investment is included in investment in unconsolidated affiliate on the consolidated balance sheets. On February 9, 2018, the property acquired by Garden 1101 was sold and the Company received a distribution from the partnership of $3.7 million which resulted in a gain from unconsolidated affiliate of $2.5 million in 2018. A gain of approximately $108,000 is included in equity in earnings of unconsolidated affiliate on the consolidated statement of operations for the year ended December 31, 2019.

Fair Value Disclosures [Abstract]
Fair Value	9. FAIR VALUE: Fair Value of Financial Instruments: The fair value of the Company’s financial instruments is determined based upon applicable accounting guidance. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The guidance requires disclosure of the level within the fair value hierarchy in which the fair value measurements fall, including measurements using quoted prices in active markets for identical assets or liabilities (Level 1), quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active (Level 2), and significant valuation assumptions that are not readily observable in the market (Level 3). The fair values of cash and cash equivalents, restricted cash, rent and other receivable s , dividends payable, accounts payable and accrued expenses approximated their carrying value because of the short-term nature based on Level 1 inputs. The fair values of mortgage notes payable and pension withdrawal liability are based on borrowing rates available to the Company, which are Level 2 inputs. The following table summarizes the carrying values and the estimated fair values of the financial instruments (in thousands): June 30, 2021 December 31, 2020 Carrying Estimated Carrying Estimated Value Value Value Value Financial assets: Cash and cash equivalents $ 40,155 $ 40,155 $ 42,255 $ 42,255 Restricted cash 2,165 2,165 1,662 1,662 Rent and other receivables 2,554 2,554 2,141 2,141 Financial liabilities: Dividends payable 1,378 1,378 1,362 1,362 Accounts payable and accrued expenses 3,291 3,291 3,949 3,949 Secured revolving credit facility 50,000 50,000 50,000 50,000 Mortgage notes payable 365,821 376,577 366,201 377,371 Pension withdrawal liability 890 956 926 1,027

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	6 Months Ended
	Jun. 30, 2021
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation: The accompanying unaudited condensed consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and include the financial statements of the Company, its wholly owned subsidiaries, and the Operating Partnership, as the Company makes all operating and financial decisions for (i.e., exercises control over) the Operating Partnership. All material intercompany transactions have been eliminated. The ownership interests of the other investors in the Operating Partnership are presented as non-controlling interests. The accompanying unaudited condensed consolidated interim financial information has been prepared according to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted in accordance with such rules and regulations. The Company’s management believes that the disclosures presented in these unaudited condensed consolidated financial statements are adequate to make the information presented not misleading. In management’s opinion, all adjustments and eliminations, consisting only of normal recurring adjustments, necessary to present fairly the financial position and results of operations for the reported periods have been included. The results of operations for such interim periods are not necessarily indicative of the results for the full year. The accompanying unaudited condensed consolidated interim financial information should be read in conjunction with the Company’s December 31, 2020, audited consolidated financial statements, as previously filed with the SEC on Form 10-K on March 25, 2021. The Company has determined that redemptions of Company shares result in a reallocation between the Operating Partnership’s non-controlling interest (“OP NCI”) and Additional Paid-in-Capital (“APIC”). During the six months ended June 30, 2021, there were no redemptions of Company shares, and therefore, no reallocation was required.
Use of Estimates	Use of Estimates: The preparation of the Company’s condensed consolidated financial statements in conformity with GAAP requires management to make estimates, judgments, and assumptions that affect the reported amounts of assets and liabilities, and related disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amount of revenues and expenses during the reporting period. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. All of these estimates reflect management’s best judgment about current economic and market conditions and their effects based on information available as of the date of these condensed consolidated financial statements. If such conditions persist longer or deteriorate further than expected, it is reasonably possible that the judgments and estimates could change, which may result in impairments of certain assets. Significant estimates include the useful lives of long-lived assets including property, equipment and intangible assets, impairment of assets, collectability of receivables, contingencies, stock-based compensation, and fair value of assets and liabilities acquired in business combinations.
Reclassification	Reclassification: None of the prior year amounts have been reclassified for consistency with the current year presentation.
Real Estate	Real Estate: Real estate assets are stated at cost, less accumulated depreciation and amortization. All costs related to the improvement or replacement of real estate properties, including interest expense on development properties, are capitalized. Acquisition related costs are capitalized for asset acquisitions. Additions, renovations, and improvements that enhance and/or extend the useful life of a property are also capitalized. Expenditures for ordinary maintenance, repairs, and improvements that do not materially prolong the normal useful life of an asset are charged to operations as incurred. The Company capitalizes all direct costs of real estate under development until the end of the development period. In addition, the Company capitalizes the indirect cost of insurance and real estate taxes allocable to real estate under development during the development period. The Company also capitalizes interest using the avoided cost method for real estate under development during the development period. The Company will cease the capitalization of these costs when development activities are substantially completed and the property is available for occupancy by tenants, but no later than one year from the completion of major construction activity at which time the property is placed in service and depreciation commences. If the Company suspends substantially all activities related to development of a qualifying asset, the Company will cease capitalization of these costs until activities are resumed. The Company had no real estate under development as of June 30, 2021 and December 31, 2020. Upon the acquisition of real estate properties, the relative fair value of the real estate purchased is allocated to the acquired tangible assets (generally consisting of land, buildings and building improvements, and tenant improvements) and identified intangible assets and liabilities (generally consisting of above-market and below-market leases and the origination value of in-place leases) on a relative fair value basis in accordance with GAAP. The Company utilizes methods similar to those used by independent appraisers in estimating the fair value of acquired assets and liabilities. The fair value of the tangible assets of an acquired property considers the value of the property “as-if-vacant.” In allocating the purchase price to identified intangible assets and liabilities of an acquired property, the value of above-market and below-market leases is estimated based on the differences between contractual rentals and estimated market rents over the applicable lease term discounted back to the date of acquisition utilizing a discount rate adjusted for the credit risk associated with the respective tenants. Fixed-rate renewal options have been included in the calculation of the fair value of acquired leases where applicable. The aggregate value of in-place leases is measured based on the avoided costs associated with lack of revenue over a market-oriented lease-up period, the avoided leasing commissions, and other avoided costs common in similar leasing transactions. Mortgage notes payable assumed in connection with acquisitions are recorded at their fair value using current market interest rates for similar debt at the time of acquisitions. The capitalized above-market lease values are amortized as a reduction of rental revenue over the remaining term of the respective leases and the capitalized below-market lease values are amortized as an increase to rental revenue over the remaining term of the respective leases. The value of in-place leases is based on the Company’s evaluation of the specific characteristics of each tenant’s lease. Factors considered include estimates of carrying costs during expected lease-up periods, current market conditions, and costs to execute similar leases. The values of in-place leases are amortized over the remaining term of the respective leases. If a tenant terminates its lease prior to its contractual expiration date, any unamortized balance of the related intangible assets or liabilities is recorded as income or expense in the period. The total net impact to rental revenues due to the amortization of above and below-market leases was a net increase of approximately $0.1 million and $0.3 million for the six months ended June 30, 2021 and June 30, 2020, respectively. As of June 30, 2021, above-market and in-place leases of approximately $0.4 million and $6.5 million (net of accumulated amortization), respectively, are included in acquired lease intangible assets, net in the accompanying condensed consolidated balance sheets. As of December 31, 2020, above-market and in-place leases of approximately $0.6 million and $7.3 million (net of accumulated amortization), respectively, are included in acquired lease intangible assets, net in the accompanying condensed consolidated balance sheets. As of June 30, 2021, and December 31, 2020, approximately $2.9 million and $3.2 million (net of accumulated amortization), respectively, relating to below-market leases are included in acquired lease intangible liabilities, net in the accompanying condensed consolidated balance sheets. The following table presents the projected impact for the remainder of 2021, the next five years and thereafter related to the net increase to rental revenue from the amortization of the acquired above-market and below-market lease intangibles and the increase to amortization expense of the in-place lease intangibles for properties owned at June 30, 2021 (in thousands): Net increase to Increase to rental revenues amortization expense Remainder of 2021 $ 294 $ 669 2022 611 1,300 2023 635 1,189 2024 498 904 2025 147 733 2026 71 603 Thereafter 258 1,106 $ 2,514 $ 6,504
Investment in Unconsolidated Affiliate	Investment in Unconsolidated Affiliate: The Company has an investment in an entity that has been accounted for under the equity method of accounting. The equity method of accounting is used when an investor has influence, but not control, over the investee. The Company records its share of the profits and losses of the investee in the period when theses profits and losses are also reflected in the accounts of the investee. On February 28, 2018, the Company purchased a 50% interest in Two CPS Developers LLC (the “Investee”) for $5.25 million. The Company has the ability to exercise significant influence over the Investee, does not have a controlling interest in the Investee, and the Investee is not a variable interest entity. Therefore, the Company accounts for this investment under the equity method of accounting. The Company recorded income of approximately $0.1 million from this investment for the six months ended June 30, 2021 and 2020, respectively. The total assets and liabilities of the Company’s investment in unconsolidated affiliate as of June 30, 2021 were $17.6 million and $10.0 million, respectively. Total revenues and expenses of the Company’s investment in unconsolidated affiliate for the six months ended June 30, 2021 were $0.8 million and $0.7 million, respectively. The total assets and liabilities of the Company’s investment in unconsolidated affiliate as of December 31, 2020 were $17.9 million and $10.0 million, respectively. Total revenues and expenses of the Company’s investment in unconsolidated affiliate for the six months ended June 30, 2020 were $0.8 million and $0.7 million, respectively.
Depreciation and Amortization	Depreciation and Amortization: The Company uses the straight-line method for depreciation and amortization. Properties and property improvements are depreciated over their estimated useful lives, which range from 5 to 40 years. Furniture, fixtures, and equipment are depreciated over estimated useful lives that range from 5 to 10 years. Tenant improvements are amortized over the shorter of the remaining non-cancellable term of the related leases or their useful lives.
Asset Impairment	Asset Impairment: Management reviews each real estate investment for impairment whenever events or circumstances indicate that the carrying value of a real estate investment may not be recoverable. The review of recoverability is based on an estimate of the undiscounted future cash flows that are expected to result from the real estate investment’s use and eventual disposition. Such cash flow analyses consider factors such as expected future operating income, trends and prospects, as well as the effects of leasing demand, competition and other factors. If an impairment event exists due to the projected inability to recover the carrying value of a real estate investment, an impairment loss is recorded to the extent that the carrying value exceeds estimated fair value. Management is required to make subjective assessments as to whether there are impairments in the value of the Company’s real estate holdings. These assessments could have a direct impact on net income, because an impairment loss is recognized in the period the assessment is made. Management has determined that there was no impairment related to its long-lived assets at June 30, 2021 or December 31, 2020.
Deferred Charges	Deferred Charges: Deferred charges consist principally of leasing commissions, which are amortized over the life of the related tenant leases, and financing costs, relating to the Company’s secured revolving credit facility, which are amortized over the terms of the respective debt agreements. These deferred charges are included in other assets on the consolidated balance sheets. If leases or loans are terminated, the unamortized charges are expensed.
Reportable Segments	Reportable Segments: The Company operates in one reportable segment, commercial real estate.
Revenue Recognition	Revenue Recognition: Rental income includes the base rent that each tenant is required to pay in accordance with the terms of their respective leases reported on a straight-line basis over the term of the lease. Rental income related to tenants where the collectability of lease payments is not deemed probable will be recorded on a cash basis. If the Company determines that the collectability of a tenant’s lease payments is not probable, then the write-off of the entire tenant receivable, including straight-line rent receivable, is presented as a reduction of revenue rather than an operating expense on the statement of operations. Some of the leases provide for additional contingent rental revenue in the form of increases based on the consumer price index, subject to certain maximums and minimums. Substantially all of the Company’s properties are subject to long-term net leases under which the tenant is typically responsible to pay for its pro rata share of real estate taxes, insurance, and ordinary maintenance and repairs for the property. Property operating expense recoveries from tenants of common area maintenance, real estate taxes, and other recoverable costs are included in revenues in the period that the related expenses are incurred. Future minimum contractual lease payments to be received by the Company (without taking into account straight-line rent, amortization of intangibles and tenant reimbursements) as of June 30, 2021, under operating leases for the remainder of 2021, the next five years, and thereafter are as follows (in thousands): Remainder of 2021 $ 25,439 2022 50,217 2023 45,734 2024 39,665 2025 37,093 2026 34,553 Thereafter 52,093 Total $ 284,794
Lease Accounting	Lease Accounting: The Company has made an accounting policy election to account for lease concessions related to the effects of COVID-19 consistent with how those concessions would be accounted for under Topic 842, which is as though the enforceable rights and obligations for those concessions existed regardless of whether those enforceable rights and obligations for the concessions explicitly exist in the contract. The Company elected to utilize the practical expedient provided by ASU 2018-11 related to the separation of lease and non-lease components and as a result, revenues related to leases are reported on one line in the presentation within the consolidated statement of operations. As lessee, the Company elected to utilize the practical expedient in the implementation of ASU 2016-02 related to not separating non-lease components from the associated lease component. As lessee, the Company is a party to an office lease which expired on December 31, 2020. The Company will continue to occupy the premises on a month-to-month basis at a current base rent of $24,000. The Company includes right-of-use assets in other assets and right-of-use liabilities as other liabilities on its consolidated balance sheet. There are no right-of-use assets or right-of-use liabilities included in other assets or other liabilities as of June 30, 2021 and December 31, 2020, respectively. The Company elected not to evaluate whether certain sales taxes and other similar taxes are lessor costs or lessee costs. Instead, these costs will be accounted for as if they are lessee costs. Consequently, the Company excludes from the consideration in the contract and from variable payments not included in the consideration in the contract all collections from lessees of taxes within the scope of the election and provides certain disclosures. The accounting policy election includes sales, use, value added, and some excise taxes but excludes real estate taxes.
Earnings Per Share Information	Earnings Per Share Information: The Company presents both basic and diluted earnings per share. Basic earnings per share excludes dilution and is computed by dividing net income attributable to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock, where such exercise or conversion would result in a lower per share amount. Restricted stock and stock options were included in the computation of diluted earnings per share.
Cash and Cash Equivalents	Cash and Cash Equivalents: The Company considers all highly liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents.
Restricted Cash	Restricted Cash: Restricted cash includes reserves used to pay real estate taxes, leasing costs and capital improvements.
Fair Value Measurement	Fair Value Measurement: The Company determines fair value in accordance with Accounting Standards Codification (“ASC”) Topic 820, “Fair Value Measurement.” This standard defines fair value, provides guidance for measuring fair value and requires certain disclosures. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Where available, fair value is based on observable market prices or parameters or derived from such prices or parameters. Where observable prices or inputs are not available, valuation models are applied. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the instruments or market and the instruments’ complexity. Assets and liabilities disclosed at fair values are categorized based upon the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels, which are defined by ASC 820-10-35, are directly related to the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities. Determining which category an asset or liability falls within the hierarchy requires significant judgment, and the Company evaluates its hierarchy disclosures each quarter. The three-tier fair value hierarchy is as follows: Level 1 — Valuations based on quoted prices for identical assets and liabilities in active markets. Level 2 — Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3 — Valuations based on unobservable inputs reflecting management’s own assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment.
Income Taxes	Income Taxes: The Company is organized and conducts its operations to qualify as a REIT for federal income tax purposes. Accordingly, the Company is generally not subject to federal income taxation on the portion of its distributable income that qualifies as REIT taxable income, to the extent that it distributes at least 90% of its REIT taxable income to its stockholders and complies with certain other requirements as defined in the Code. The Company also participates in certain activities conducted by entities which elected to be treated as taxable subsidiaries under the Code. As such, the Company is subject to federal, state, and local taxes on the income from these activities. The Company accounts for income taxes under the asset and liability method as required by the provisions of ASC 740-10-30. Under this method, deferred tax assets and liabilities are established based on differences between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company provides a valuation allowance for deferred tax assets for which it does not consider realization of such assets to be more likely than not. ASC 740-10-65 addresses the determination of whether tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. Under ASC 740-10-65, the Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position should be measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. ASC 740-10-65 also provides guidance on de-recognition, classification, interest and penalties on income taxes, and accounting in interim periods and requires increased disclosures. As of June 30, 2021, and December 31, 2020, the Company had determined that no liabilities are required in connection with uncertain tax positions. As of June 30, 2021, the Company’s tax returns for the prior three years are subject to review by the Internal Revenue Service. Any interest and penalties would be expensed as incurred.
Concentrations of Credit Risk	Concentrations of Credit Risk: Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents, which from time-to-time exceed the federal depository insurance coverage. Beginning January 1, 2013, all interest and noninterest bearing transaction accounts deposited at an insured depository institution are insured by the Federal Deposit Insurance Corporation up to the standard maximum deposit amount of $250,000. Management believes that the Company is not exposed to any significant credit risk due to the credit worthiness of the financial institutions. For the six months ended June 30, 2021, rental income of $4.8 million derived from five leases with the City of New York represents approximately 15% of the Company’s rental income.
Stock-Based Compensation	Stock-Based Compensation: The Company has a stock-based compensation plan which is described below in Note 5. The Company accounts for stock-based compensation in accordance with ASC Topic 718, “Compensation – Stock Compensation,” which establishes accounting for stock-based awards exchanged for employee services. Under the provisions of ASC Topic 718, share-based compensation cost is measured at the grant date or service-inception date (if it precedes the grant date), based on the fair value of the award. Share-based compensation is expensed at the grant date (for awards or portion of awards that vested immediately), or ratably over the respective vesting periods, determined from the start of the grant date or service-inception date through the date of vesting.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements: In January 2021, the Financial Accounting Standards Board (“FASB”) issued ASU 2021-01, “Reference Rate Reform (Topic 848),” which modifies ASC 848 (ASU 2020-04 discussed below), which was intended to provide relief related to “contracts and transactions that reference LIBOR or a reference rate that is expected to be discontinued as a result of reference rate reform.” ASU 2021-01 expands the scope of ASC 848 to include all affected derivatives and give reporting entities the ability to apply certain aspects of the contract modification and hedge accounting expedients to derivative contracts affected by the discounting transition. ASU 2021-01 also adds implementation guidance to clarify which optional expedients in ASC 848 may be applied to derivative instruments that do not reference LIBOR or a reference rate that is expected to be discontinued, but that are being modified as a result of the discounting transition. The Company does not have any derivative transactions to which this ASU applied. As a result, the implementation of this guidance is not expected to have a material effect on the Company’s consolidated financial statements. In March 2020, the FASB issued ASU No. 2020-04, “Reference Rate Reform (Topic 848) – Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” The new guidance provides optional expedients and exceptions for applying generally accepted accounting principles when accounting for contract modifications, hedging relationships and other transactions impacted by rate reform, subject to meeting certain criteria. ASU 2020-04 is effective as of March 12, 2020 through December 31, 2022. The Company had no transactions to which the ASU was applied since adoption and we are considering the impact of reference rate reform on our consolidated financial statements.
