Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation. The accompanying condensed consolidated financial statements have been prepared by the Company's management in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial statement and the instructions to Form 10-Q and Article 8 of Regulation S-X. Certain information and footnote disclosures required for annual consolidated financial statements have been condensed or excluded pursuant to rules and regulations of the SEC. In the opinion of management, the accompanying condensed consolidated financial statements reflect all adjustments of a normal and recurring nature that are considered necessary for a fair presentation of our financial position, results of our operations, and cash flows as of and for the three months ended March 31, 2020 and 2019, respectively. However, the results of operations for the interim periods are not necessarily indicative of the results that may be expected for the year ending December 31, 2020. These condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2019. The condensed consolidated balance sheet as of December 31, 2019 has been derived from the audited consolidated financial statements included in the Form 10-K filed with the SEC on March 13, 2020. The results for the three months ended March 31, 2020 are not necessarily indicative of the results to be expected for the full year ending December 31, 2020 due to seasonal variations and other factors, such as the effects of the novel coronavirus (“COVID-19”) and its possible influence on our future results.
Principles of Consolidation	Principles of Consolidation. The accompanying condensed consolidated financial statements include the accounts of the Company and its direct and indirect wholly-owned subsidiaries and entities the Company controls or of which it is the primary beneficiary. All significant intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Significant estimates include the allocation of purchase price paid for property acquisitions among land, building and intangible assets acquired including their useful lives; valuation of long-lived assets, and the allowance for doubtful accounts, which is based on an evaluation of the tenants’ ability to pay. Actual results may differ from those estimates.
Cash Equivalents and Restricted Cash	Cash Equivalents and Restricted Cash. At March 31, 2020 and December 31, 2019, we had approximately $6.1 million and $5.7 million in cash equivalents, respectively, and $2.9 million and $4.7 million of restricted cash, respectively. Our cash equivalents and restricted cash consist of invested cash and cash in our operating accounts and are held in bank accounts at third party institutions. Restricted cash consists of funds used for property taxes, insurance, capital expenditures and leasing commissions.
Real Estate Held for Sale	Real Estate Held for Sale. Real estate held for sale during the current period is classified as “real estate held for sale” for all prior periods presented in the accompanying condensed consolidated financial statements. Mortgage notes payable related to the real estate held for sale during the current period are classified as “mortgage notes payable related to real estate held for sale, net” for all prior periods presented in the accompanying condensed consolidated financial statements. As of March 31, 2020, three properties meet the criteria to be classified as held for sale, which are World Plaza, Garden Gateway and one of the four buildings at Executive Office Park.
Impairments of Real Estate Asset	Impairments of Real Estate Asset. We review for impairment on a property by property basis. Impairment is recognized on properties held for use when the expected undiscounted cash flows for a property are less than its carrying amount at which time the property is written-down to fair value. The calculation of both discounted and undiscounted cash flows requires management to make estimates of future cash flows including revenues, operating expenses, required maintenance and development expenditures, market conditions, demand for space by tenants and rental rates over long periods. Since our properties typically have a long life, the assumptions used to estimate the future recoverability of carrying value requires significant management judgment. Actual results could be significantly different from the estimates. These estimates have a direct impact on net income because recording an impairment charge results in a negative adjustment to net income. The evaluation of anticipated cash flows is highly subjective and is based in part on assumptions regarding future occupancy, rental rates and capital requirements that could differ materially from actual results in future periods. Properties held for sale are recorded at the lower of the carrying amount or the expected sales price less costs to sell. Although our strategy is to hold our properties over the long-term, if our strategy changes or market conditions otherwise dictate an earlier sale date, an impairment loss may be recognized to reduce the property to fair value and such loss could be material.
Fair Value Measurements	Fair Value Measurements. Under GAAP, we are required to measure certain financial instruments at fair value on a recurring basis. In addition, we are required to measure other non-financial and financial assets at fair value on a non-recurring basis (e.g., carrying value of impaired real estate loans receivable and long-lived assets). Fair value is defined as the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The GAAP fair value framework uses a three-tiered approach. Fair value measurements are classified and disclosed in one of the following three categories: •Level 1: unadjusted quoted prices in active markets that are accessible at the measurement date for identical assets or liabilities; •Level 2: quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which significant inputs and significant value drivers are observable in active markets; and •Level 3: prices or valuation techniques where little or no market data is available that requires inputs that are both significant to the fair value measurement and unobservable. When available, we utilize quoted market prices from independent third-party sources to determine fair value and classify such items in Level 1 or Level 2. In instances where the market for a financial instrument is not active, regardless of the availability of a nonbinding quoted market price, observable inputs might not be relevant and could require us to make a significant adjustment to derive a fair value measurement. Additionally, in an inactive market, a market price quoted from an independent third party may rely more on models with inputs based on information available only to that independent third party. When we determine the market for a financial instrument owned by us to be illiquid or when market transactions for similar instruments do not appear orderly, we use several valuation sources (including internal valuations, discounted cash flow analysis and quoted market prices) and establish a fair value by assigning weights to the various valuation sources. Additionally, when determining the fair value of a liability in circumstances in which a quoted price in an active market for an identical liability is not available, we measure fair value using (i) a valuation technique that uses the quoted price of the identical liability when traded as an asset or quoted prices for similar liabilities when traded as assets or (ii) another valuation technique that is consistent with the principles of fair value measurement, such as the income approach or the market approach. Changes in assumptions or estimation methodologies can have a material effect on these estimated fair values. In this regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, may not be realized in an immediate settlement of the instrument.
Subsequent Events	Subsequent Events. We evaluate subsequent events up until the date the consolidated financial statements are issued. Correction of Previously Issued Financial Information. We have corrected certain information in the current quarter related to the subsequent event disclosure surrounding the sale of Centennial Technology Center as well certain information related to our Segments footnote as reported in our Annual Report on Form 10-K for the year ended December 31, 2019 filed with the Securities and Exchange Commission (“SEC”) on March 13, 2020. These corrections were disclosure based in nature and had no impact on our previously reported financial statements as of December 31, 2019.
Recently Issued and Adopted Accounting Pronouncements	Recently Issued and Adopted Accounting Pronouncements. In March 2020, the FASB issued Accounting Standards Update (“ASU”) No. 2020-04, Reference Rate Reform which provides optional expedients and exceptions in order to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting as it relates to contracts, hedging relationships and other transactions by allowing companies to modify contracts that previously contained LIBOR rates without evaluating whether the modification constituted a new contract. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, and are used on a prospective basis upon adoption. The Company adopted this guidance as of March 2020 noting no impact to the financial statements. In March 2017, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses, amended in February 2020 with ASU No. 2020-02, Financial Instruments—Credit Losses (Topic 326) and Leases (Topic 842). ASU 2016-13 introduces a new model for estimating credit losses for certain types of financial instruments, including loans receivable, held-to-maturity debt securities, and net investments in direct financing leases, amongst other financial instruments. ASU 2016-13 also modifies the impairment model for available-for-sale debt securities and expands the disclosure requirements regarding an entity’s assumptions, models, and methods for estimating the allowance for losses. While ASU 2016-13 was effective for periods beginning after December 15, 2019, the issuance of ASU 2020-02 has allowed for the delay in adoption for certain smaller public companies, and is now effective for fiscal periods beginning after December 15, 2022. Retrospective adjustments shall be applied through a cumulative-effect adjustment to retained earnings. The Company is continuing to evaluate the impact of this guidance on its financial statements. In August 2018, the FASB issued ASU No. 2018-13, Disclosure Framework — Changes to the Disclosure Requirements for Fair Value Measurement which removes, modifies, and adds certain disclosure requirements related to fair value measurements in ASC 820. This guidance is effective for public companies in fiscal years beginning after December 15, 2019 with early adoption permitted. The Company adopted this guidance as of January 1, 2020 and noted no impact on its consolidated financial statements.
