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 23, 2006, under Maryland General Corporation Law. The Company is focused primarily on the acquisition, ownership, management, and operation of commercial real estate located in the New York tri-state area.
	The Company has elected to be treated as a real estate investment trust, or REIT, under the Internal Revenue Code of 1986, as amended and 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 interests in the Operating Partnership; the owner of all 32 properties as of December 31, 2013. 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. As a result of this acquisition and the six properties acquired in 2014, the Company currently beneficially owns a 66.71% interest in a total of 38 properties (including the seven previously-owned properties) consisting of approximately 3.4 million square feet of office and industrial properties on 269 acres of land in New York, New Jersey, and Connecticut. At December 31, 2014, subject to certain anti-dilutive and other provisions contained in the governing agreements, the limited partnership interests in the Operating Partnership may be convertible in the aggregate, into approximately 1.8 million shares of the Company’s common stock and approximately 5.0 million shares of Series B preferred stock.
	Prior to 2013, the Company had operated a group of outdoor maintenance, shelter cleaning, and electrical contracting businesses, as well as a parking garage facility. During 2011, the Board voted to divest these operations which were sold in 2012 and 2013. Accordingly, the operations of these entities are reported as discontinued operations in the statements of operations.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
	Basis of Presentation:
	The accompanying 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 in consolidation. Certain prior period amounts have been reclassified to conform to the 2014 financial statement presentation. The ownership interests of the other investors in the Operating Partnership are recorded as noncontrolling interests. Certain prior period amounts have been reclassified to conform to the current presentation.
	Use of Estimates:
	The preparation of the Company’s 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 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, and stock-based compensation.
	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 are capitalized. 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.
	Upon the acquisition of real estate properties, the 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) in accordance with GAAP. We utilize 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 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 the 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. Acquisition related costs are expensed as incurred. 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 vacates its space 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 in rental revenue of approximately $0.3 million for the year ended December 31, 2014.
	As of December 31, 2014, approximately $2.5 million and $13.1 million (net of accumulated amortization) relating to above-market and in-place leases, respectively, are included in acquired lease intangible assets, net in the accompanying consolidated balance sheet. Approximately $7.8 million (net of accumulated amortization) relating to below-market leases is included in acquired lease intangible liabilities, net in the accompanying consolidated balance sheet.
	The following table presents the projected 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 December 31, 2014 , over the next five years and thereafter (in thousands):

	2019		564		955
	Thereafter		2,724		4,925
		$	5,196	$	13,076
	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.
	Deferred Charges:
	Deferred charges consist principally of leasing commissions, which are amortized ratably over the life of the related tenant leases, and financing costs, which are amortized over the terms of the respective debt agreements. These deferred charges are included in other assets on the consolidated balance sheets.
	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 its real estate holdings. These assessments could have a direct impact on net income, because an impairment loss is recognized in the period that the assessment is made. Management has determined that there were no indicators of impairment relating to its long-lived assets at December 31, 2014.
	Reportable Segments:
	As of December 31, 2014, the Company primarily operated 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. In order for management to determine, in its judgment, that the unbilled rent receivable applicable to each specific property is collectible, management reviews billed and unbilled rent receivables on a quarterly basis and takes into consideration the tenant’s payment history and financial condition. Some of the leases provide for additional contingent rental revenue in the form of percentage rents and 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 their 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, and other recoverable costs are recognized as revenues in the period that the related expenses are incurred.
	Earnings Per Share Information:
	The Company presents both basic and diluted earnings (loss) per share. Basic earnings (loss) per share excludes dilution and is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings (loss) 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 was included in the computation of diluted earnings (loss) per share and stock option awards were excluded from the computation of diluted earnings (loss) per share because the option awards would have been antidilutive for the periods presented.
	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 represents reserves used to pay real estate taxes, insurance, and tenant improvements. At December 31, 2014 and 2013, the Company had restricted cash of $1.0 million and $1.3 million, respectively, which was included in other assets on the consolidated balance sheets.
	Fair Value Measurement:
	The Company determines fair value in accordance with Accounting Standards Codification (“ASC”) 820-10-05 for financial assets and liabilities. 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 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.
	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.
	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, accounting in interim periods and requires increased disclosures. As of December 2014 and 2013, the Company had determined that no liabilities are required in connection with unrecognized tax positions. As of December 31, 2014, the Company’s tax returns for the prior three years are subject to review by the Internal Revenue Service.
	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 noninterest bearing transaction accounts deposited at an insured depository institution are insured by the Federal Deposit Insurance Corporation up to the standard maximum deposit insurance 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.
	Stock-Based Compensation:
	The Company has a stock-based compensation plan, which is described below in Note 7. The Company accounts for stock-based compensation in accordance with ASC 718-30-30, which establishes accounting for stock-based awards exchanged for employee services. Under the provisions of ASC 718-10-35, share-based compensation cost is measured at the grant date, based on the fair value of the award, and is expensed at the grant date (for the portion that vests immediately) or ratably over the respective vesting periods.
	New Accounting Pronouncements:
	In February 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-02, “Consolidation (Topic 810) – Amendments to the Consolidation Analysis.” ASU 2015-02 amends the consolidation requirements in Accounting Standards Codification (“ASC”) 810 “Consolidation” and changes the required consolidation analysis.  The amendments in ASU No. 2015-02 affect reporting entities that are required to evaluate whether they should consolidate certain legal entities. The amendments impact limited partnerships and legal entities, the evaluation of fees paid to a decision maker or service provider of a variable interest, the effect of fee arrangements on the primary beneficiary determination, the effect of related parties on the primary beneficiary determination, and certain investment funds.  ASU No. 2015-02 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. The Company is currently evaluating the impact of its pending adoption of ASU 2015-02 on its consolidated financial statements.
	In January 2015, the FASB issued ASU No. 2015-01, “Income Statement – Extraordinary and Unusual Items.” ASU 2015-01 eliminates the concept of extraordinary items.  However, the presentation and disclosure requirements for items that are either unusual in nature of infrequent in occurrence remain and will be expanded to include items that are both unusual in nature and infrequent in occurrence. ASU 2015-01 is effective for periods beginning after December 15, 2015.  ASU 2015-01 is not expected to have a material impact on the Company’s consolidated financial statements.
	In August 2014, the FASB issued ASU No. 2014-15, “Presentation of Financial Statements – Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.”  The amendments in ASU 2014-15 are intended to define management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. Under GAAP, financial statements are prepared under the presumption that the reporting organization will continue to operate as a going concern, except in limited circumstances. The going concern basis of accounting is critical to financial reporting because it establishes the fundamentals of measuring and classifying assets and liabilities. This ASU provides guidance to an organization’s management, with principles and definitions that are intended to reduce diversity in the timing and content of disclosures that are commonly provided by organizations in financial statement footnotes. This accounting standard is effective for annual periods ending after December 15, 2016, and interim periods within annual periods beginning after December 15, 2016.  Early adoption is permitted.  The Company is currently evaluating the impact of its pending adoption of ASU 2014-15 on its consolidated financial statements.
	During June 2014, the FASB issued ASU No. 2014-12, “Accounting for Share-Based Payments when the Terms of an Award Profile That a Performance Target Could be Achieved after the Requisite Service Period.” ASU 2014-12 provides explicit guidance on how to account for share-based payments that require a specific performance target to be achieved which may be achieved after an employee completes the requisite service period. ASU 2014-12 is effective for periods beginning after December 15, 2015 and may be applied either prospectively or retrospectively. ASU 2014-12 is not expected to have a material impact on the Company’s consolidated financial statements.
	During May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers,” which supersedes nearly all existing revenue recognition guidance under GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing GAAP. The standard is effective for annual periods beginning after December 15, 2016, and interim periods therein, using either of the following transaction methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). The Company is currently evaluating the impact of its pending adoption of ASU 2014-09 on its consolidated financial statements and has not yet determined the method by which the standard will be adopted in 2017.
	In April 2014, the FASB issued 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.” The amendments in ASU 2014-08 change the criteria for reporting a discontinued operation and require new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. Only disposals representing a strategic shift in operations should be presented as discontinued operations. This accounting standards update is effective for annual filings beginning on or after December 15, 2014. Early adoption is permitted.  The impact of the adoption of ASU 2014-08 on the Company’s results of operations, financial position, cash flows and disclosures will be based on the Company’s future disposal activity.

Secured Revolving Credit Facility	12 Months Ended

Line Of Credit Facility [Abstract]
Secured Revolving Credit Facility	6. SECURED REVOLVING CREDIT FACILITY:
	M&T Financing Agreement:
	On August 26, 2011, the Company and Manufacturers and Traders Trust Company (“M&T”) entered into a certain credit agreement which provided for, among other things, a $10.0 million revolving credit facility (the “Revolver”). The Revolver was available to the Company for acquisitions and for general working capital and other corporate purposes. The Company’s obligations under this credit agreement were satisfied in full on February 22, 2013 and the Revolver was cancelled.
	Capital One Loan Agreement:
	On April 8, 2014, the Company entered into a Loan Agreement (the “Loan Agreement”) with Capital One, N.A. (the “Lender”). The Loan Agreement is for a $45.0 million senior revolving credit facility, secured by certain properties located in NYC (the “NYC Borrowers”) by means of, among other things, negative pledges relating to such properties. The intended uses of the proceeds of this facility include funding of the acquisitions of additional properties as well as working capital expenditures.
	The facility is a full obligation of the NYC Borrowers, together with GTJ REIT, Inc. and GTJ Realty, LP (the “Guarantors”). Subject to certain conditions, the facility is available at any time prior to the April 2016 maturity of this facility, in minimum principal amounts of $1.0 million. Due to the revolving nature of the facility, amounts prepaid under the facility may be borrowed again. The line of credit facility has an initial term of two years, with a one-year extension option, subject to certain other customary conditions. The NYC Borrowers may prepay the facility, in whole or in part, at any time without fees or penalty, subject to reimbursement of the Lender’s breakage costs associated with the prepayment of LIBOR rate loans. The interest-only facility includes a floating rate using (i) LIBOR plus an applicable margin (200 basis points (bps) to 335 bps), or (ii) base rate plus an applicable margin, depending upon the overall leverage of the properties. A commitment fee of 35 bps (if less than 50% of the facility is used), and 25 bps (if 50% or more is being used) will accrue on unused portions of the commitments under the facility.
	The principal amount of the line of credit facility and all interest, fees, and other amounts owing under the line of credit are guaranteed by the Guarantors under the terms and provisions of the Guaranty Agreement (the “Guaranty”). The continuing ability to borrow under the line of credit facility will be subject to the ongoing compliance of the Guarantors and the NYC Borrowers with various affirmative and negative covenants, including, among others, with respect to liens, indebtedness, investments, and distributions. The Loan 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 Loan Agreement includes customary representations and warranties of the Guarantors and the NYC Borrowers, which must continue to be true and correct in all material respects as a condition to future draws. In addition, the Loan Agreement also includes customary events of default, in certain cases subject to customary cure, following which, amounts outstanding under the facility may be accelerated.
	On November 20, 2014, the above-referenced parties executed an amendment to the Loan Agreement to increase the credit facility from $45.0 million to $60.0 million. The additional credit facility extension was underwritten by People's United Bank. The terms and provisions of the extension are substantially the same as the one under the original credit facility. The parties also entered into several side agreements and instruments to facilitate the transactions contemplated under the foregoing amendment.
	As of December 31, 2014 the outstanding balance on the Company’s revolving credit facility was $43.8 million.
	On February 20, 2015, the Company secured a loan facility in the principal amount of $233.1 million. Using proceeds available under the loan facility, the Company repaid the outstanding balance on the revolving credit facility of approximately $56.0 million, thereby paying off and terminating the revolving credit facility.

	In order to qualify as a REIT, the Company must distribute at least 90% of its taxable income and must distribute 100% of its taxable income in order not to be subject to corporate federal income taxes on retained income. The Company anticipates it will distribute all of its taxable income to its stockholders. Because taxable income differs from cash flow from operations due to non-cash revenues or expenses (such as depreciation), in certain circumstances, the Company may generate operating cash flow in excess of its distributions or, alternatively, may be required to borrow to make sufficient distribution payments.
	Stock Based Compensation:
	On June 11, 2007, the Board of Directors approved the Company’s 2007 Incentive Award Plan (the “Plan”). The Plan covers directors, officers, key employees and consultants of the Company. The purposes of the Plan are to further the growth, development, and financial success of the Company and to obtain and retain the services of the individuals considered essential to the long-term success of the Company. The Plan may provide for awards in the form of restricted shares, incentive stock options, non-qualified stock options and stock appreciation rights. The aggregate number of shares of common stock which may be awarded under the Plan is 1,000,000 shares. As of December 31, 2014, the Company had 446,296 shares available for future issuance of awards under the Plan. Dividends paid on restricted shares are recorded as dividends on shares of the Company’s common stock whether or not they are vested. In accordance the ASC 718-10-35, the Company measures the compensation costs for these shares as of the date of the grant and the expense is recognized in earnings, at the grant date (for the portion that vest immediately) or ratably over the respective vesting periods.
	On February 7, 2008, 55,000 options were granted to non-employee directors and vested immediately and 200,000 options were granted to key officers of the Company and had a three year vesting period. On June 9, 2011, the Company granted 10,000 options to a non-employee director and vested immediately. No options were exercised during 2013 or 2014. All options expire ten years from the date of grant. For the years ended December 31, 2014 and 2013, there was no stock compensation expense relating to these stock option grants.
	On April 30, 2012, and June 7, 2012, the Company issued an aggregate of 55,149 and 5,884 restricted shares of common stock, respectively, under the Plan. The shares issued on June 7, 2012 have a value of approximately $40,000 ($6.80 per share), were granted to non-management members of the Board of Directors, and vested immediately. The shares issued on April 30, 2012 have a value of approximately $375,000 ($6.80 per share), were granted to certain executives of the Company, and vest ratably over a four year period. One fourth of the shares granted to the executives vested on the grant date and one fourth will vest each year on the following dates: April 30, 2013, April 30, 2014, and April 30, 2015.

Fair Value	11. FAIR VALUE:
	Fair Value of Financial Instruments:
	The fair value of the Company’s financial instruments are 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 process in active markets for identical assets or liabilities (Level 1), quoted process for similar instruments in active markets or quoted process 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, accounts receivable, accounts payable and accrued expenses, available-for-sale securities and secured revolving credit facility 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):

	The Company elected to be taxed as a REIT under the Internal Revenue Code. A REIT will generally not be subject to federal income taxation on that portion of its income that qualifies as REIT taxable income, to the extent that it distributes at least 90% of its taxable income to its shareholders and complies with certain other requirements. It is management’s intention to adhere to these requirements and maintain the Company’s REIT status. If the Company fails to qualify as a REIT in any taxable year, it will be subject to federal income taxes at regular corporate rates (including any applicable minimum tax and may not be able to qualify as a REIT for subsequent taxable years). Even if the Company qualifies for taxation as a REIT, the Company may be subject to certain state and local taxes on its income and federal income and excise taxes on its undistributed taxable income. In addition, taxable income from non-REIT activities managed through taxable REIT subsidiaries are subject to federal, state, and local income taxes.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation:
	The accompanying 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 in consolidation. Certain prior period amounts have been reclassified to conform to the 2014 financial statement presentation. The ownership interests of the other investors in the Operating Partnership are recorded as noncontrolling interests. Certain prior period amounts have been reclassified to conform to the current presentation.
Use of Estimates	Use of Estimates:
	The preparation of the Company’s 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 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, and stock-based compensation.
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 are capitalized. 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.
	Upon the acquisition of real estate properties, the 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) in accordance with GAAP. We utilize 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 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 the 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. Acquisition related costs are expensed as incurred. 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 vacates its space 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 in rental revenue of approximately $0.3 million for the year ended December 31, 2014.
	As of December 31, 2014, approximately $2.5 million and $13.1 million (net of accumulated amortization) relating to above-market and in-place leases, respectively, are included in acquired lease intangible assets, net in the accompanying consolidated balance sheet. Approximately $7.8 million (net of accumulated amortization) relating to below-market leases is included in acquired lease intangible liabilities, net in the accompanying consolidated balance sheet.
	The following table presents the projected 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 December 31, 2014 , over the next five years and thereafter (in thousands):
				Increase to
		Net increase to		amortization
		rental revenues		expense
	2015	$	381	$	2,739
	2016		573		1,913

	2018		488		1,189
	2019		564		955
	Thereafter		2,724		4,925
		$	5,196	$	13,076
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.
Deferred Charges	Deferred Charges:
	Deferred charges consist principally of leasing commissions, which are amortized ratably over the life of the related tenant leases, and financing costs, which are amortized over the terms of the respective debt agreements. These deferred charges are included in other assets on the consolidated balance sheets.
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 its real estate holdings. These assessments could have a direct impact on net income, because an impairment loss is recognized in the period that the assessment is made. Management has determined that there were no indicators of impairment relating to its long-lived assets at December 31, 2014.
Reportable Segments	Reportable Segments:
	As of December 31, 2014, the Company primarily operated 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. In order for management to determine, in its judgment, that the unbilled rent receivable applicable to each specific property is collectible, management reviews billed and unbilled rent receivables on a quarterly basis and takes into consideration the tenant’s payment history and financial condition. Some of the leases provide for additional contingent rental revenue in the form of percentage rents and 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 their 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, and other recoverable costs are recognized as revenues in the period that the related expenses are incurred.
Earnings Per Share Information	Earnings Per Share Information:
	The Company presents both basic and diluted earnings (loss) per share. Basic earnings (loss) per share excludes dilution and is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings (loss) 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 was included in the computation of diluted earnings (loss) per share and stock option awards were excluded from the computation of diluted earnings (loss) per share because the option awards would have been antidilutive for the periods presented.
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 represents reserves used to pay real estate taxes, insurance, and tenant improvements. At December 31, 2014 and 2013, the Company had restricted cash of $1.0 million and $1.3 million, respectively, which was included in other assets on the consolidated balance sheets.
Fair Value Measurement	Fair Value Measurement:
	The Company determines fair value in accordance with Accounting Standards Codification (“ASC”) 820-10-05 for financial assets and liabilities. 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 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.
	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.
	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, accounting in interim periods and requires increased disclosures. As of December 2014 and 2013, the Company had determined that no liabilities are required in connection with unrecognized tax positions. As of December 31, 2014, the Company’s tax returns for the prior three years are subject to review by the Internal Revenue Service.
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 noninterest bearing transaction accounts deposited at an insured depository institution are insured by the Federal Deposit Insurance Corporation up to the standard maximum deposit insurance 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.
Stock-Based Compensation	Stock-Based Compensation:
	The Company has a stock-based compensation plan, which is described below in Note 7. The Company accounts for stock-based compensation in accordance with ASC 718-30-30, which establishes accounting for stock-based awards exchanged for employee services. Under the provisions of ASC 718-10-35, share-based compensation cost is measured at the grant date, based on the fair value of the award, and is expensed at the grant date (for the portion that vests immediately) or ratably over the respective vesting periods.
New Accounting Pronouncements	New Accounting Pronouncements:
	In February 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-02, “Consolidation (Topic 810) – Amendments to the Consolidation Analysis.” ASU 2015-02 amends the consolidation requirements in Accounting Standards Codification (“ASC”) 810 “Consolidation” and changes the required consolidation analysis.  The amendments in ASU No. 2015-02 affect reporting entities that are required to evaluate whether they should consolidate certain legal entities. The amendments impact limited partnerships and legal entities, the evaluation of fees paid to a decision maker or service provider of a variable interest, the effect of fee arrangements on the primary beneficiary determination, the effect of related parties on the primary beneficiary determination, and certain investment funds.  ASU No. 2015-02 is effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. The Company is currently evaluating the impact of its pending adoption of ASU 2015-02 on its consolidated financial statements.
	In January 2015, the FASB issued ASU No. 2015-01, “Income Statement – Extraordinary and Unusual Items.” ASU 2015-01 eliminates the concept of extraordinary items.  However, the presentation and disclosure requirements for items that are either unusual in nature of infrequent in occurrence remain and will be expanded to include items that are both unusual in nature and infrequent in occurrence. ASU 2015-01 is effective for periods beginning after December 15, 2015.  ASU 2015-01 is not expected to have a material impact on the Company’s consolidated financial statements.
	In August 2014, the FASB issued ASU No. 2014-15, “Presentation of Financial Statements – Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern.”  The amendments in ASU 2014-15 are intended to define management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. Under GAAP, financial statements are prepared under the presumption that the reporting organization will continue to operate as a going concern, except in limited circumstances. The going concern basis of accounting is critical to financial reporting because it establishes the fundamentals of measuring and classifying assets and liabilities. This ASU provides guidance to an organization’s management, with principles and definitions that are intended to reduce diversity in the timing and content of disclosures that are commonly provided by organizations in financial statement footnotes. This accounting standard is effective for annual periods ending after December 15, 2016, and interim periods within annual periods beginning after December 15, 2016.  Early adoption is permitted.  The Company is currently evaluating the impact of its pending adoption of ASU 2014-15 on its consolidated financial statements.
	During June 2014, the FASB issued ASU No. 2014-12, “Accounting for Share-Based Payments when the Terms of an Award Profile That a Performance Target Could be Achieved after the Requisite Service Period.” ASU 2014-12 provides explicit guidance on how to account for share-based payments that require a specific performance target to be achieved which may be achieved after an employee completes the requisite service period. ASU 2014-12 is effective for periods beginning after December 15, 2015 and may be applied either prospectively or retrospectively. ASU 2014-12 is not expected to have a material impact on the Company’s consolidated financial statements.
	During May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers,” which supersedes nearly all existing revenue recognition guidance under GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing GAAP. The standard is effective for annual periods beginning after December 15, 2016, and interim periods therein, using either of the following transaction methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). The Company is currently evaluating the impact of its pending adoption of ASU 2014-09 on its consolidated financial statements and has not yet determined the method by which the standard will be adopted in 2017.
	In April 2014, the FASB issued 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.” The amendments in ASU 2014-08 change the criteria for reporting a discontinued operation and require new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation. Only disposals representing a strategic shift in operations should be presented as discontinued operations. This accounting standards update is effective for annual filings beginning on or after December 15, 2014. Early adoption is permitted.  The impact of the adoption of ASU 2014-08 on the Company’s results of operations, financial position, cash flows and disclosures will be based on the Company’s future disposal activity.
