Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization Griffin Realty Trust, Inc. (formerly known as Griffin Capital Essential Asset REIT, Inc.) (“GRT” or the “Company”) is an internally managed, publicly registered non-traded real estate investment trust (“REIT”) that owns and operates a geographically diversified portfolio of corporate office and industrial properties that are primarily net-leased. GRT’s fiscal year-end is December 31. On December 14, 2018, GRT, Griffin Capital Essential Asset Operating Partnership II, L.P. (the “GCEAR II Operating Partnership”), GRT’s wholly-owned subsidiary Globe Merger Sub, LLC (“EA Merger Sub”), the entity formerly known as Griffin Capital Essential Asset REIT, Inc. (“EA-1”), and GRT OP, L.P. (formerly known as Griffin Capital Essential Asset Operating Partnership, L.P.) (the “GRT OP”) entered into an Agreement and Plan of Merger (the “EA Merger Agreement”). On April 30, 2019, pursuant to the EA Merger Agreement, (i) EA-1 merged with and into EA Merger Sub, with EA Merger Sub surviving as GRT’s direct, wholly-owned subsidiary (the “EA Company Merger”) and (ii) the GCEAR II Operating Partnership merged with and into the GRT OP (the “EA Partnership Merger” and, together with the EA Company Merger, the “EA Mergers”), with the GRT OP surviving the EA Partnership Merger. In addition, on April 30, 2019, following the EA Mergers, EA Merger Sub merged into GRT. On March 1, 2021, the Company completed its acquisition of Cole Office & Industrial REIT (CCIT II), Inc. (“CCIT II”) for approximately $1.3 billion, including transaction costs, in a stock-for-stock transaction (the “CCIT II Merger”). At the effective time of the CCIT II Merger, each issued and outstanding share of CCIT II Class A common stock and each issued and outstanding share of CCIT II Class T common stock were converted into the right to receive 1.392 shares of the Company's Class E common stock. On July 1, 2021, the Company changed its name from Griffin Capital Essential Asset REIT, Inc. to Griffin Realty Trust, Inc. and the GRT OP changed its name from Griffin Capital Essential Asset Operating Partnership, L.P. to GRT OP, L.P. The GRT OP owns, directly or indirectly, all of the properties that the Company has acquired. As of September 30, 2022, (i) the Company owned approximately 91.0% of the outstanding common limited partnership units of the GRT OP (“GRT OP Units”), (ii), the former sponsor and certain of its affiliates owned approximately 7.8% of the limited partnership units of the GRT OP, including approximately 2.4 million units owned by the Company’s Executive Chairman and Chairman of the Company's Board of Directors (the “Board”), Kevin A. Shields, a result of the contribution of five properties to the Company and the self-administration transaction, and (iii) the remaining approximately 1.2% GRT OP Units are owned by unaffiliated third parties. The GRT OP may conduct certain activities through one or more of the Company’s taxable REIT subsidiaries, which are wholly-owned subsidiaries of the GRT OP. As of September 30, 2022, the Company had issued 287,136,954 shares (approximately $2.8 billion) of common stock since November 9, 2009 in various private offerings, public offerings, distribution reinvestment plan (“DRP”) offerings and mergers (includes EA-1 offerings and EA-1 merger with Signature Office REIT, Inc. and the CCIT II Merger). There were 324,066,902 shares of common stock outstanding as of September 30, 2022, including shares issued pursuant to the DRP, less shares redeemed pursuant to the share redemption program ("SRP") and self-tender offer. As of September 30, 2022 and December 31, 2021, the Company had issued approximately $341.1 million in shares pursuant to the DRP.

Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies There have been no significant changes to the Company’s accounting policies since the Company filed its audited financial statements in its Annual Report on Form 10-K for the year ended December 31, 2021. For further information about the Company’s accounting policies, refer to the Company’s consolidated financial statements and notes thereto for the year ended included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”). The accompanying unaudited consolidated financial statements of the Company are prepared by management on the accrual basis of accounting and in accordance with generally accepted accounting principles in the United States (“GAAP”) for interim financial information as contained in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”), and in conjunction with rules and regulations of the SEC. Certain information and footnote disclosures required for annual financial statements have been condensed or excluded pursuant to SEC rules and regulations. Accordingly, the unaudited consolidated financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. The unaudited consolidated financial statements include accounts and related adjustments, which are, in the opinion of management, of a normal recurring nature and necessary for a fair presentation of the Company’s financial position, results of operations and cash flows for the interim period. Operating results for the nine months ended September 30, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022. These unaudited consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 . In addition, see the risk factors identified in the “Risk Factors” section of the Company's Annual Report on Form 10-K for the year ended December 31, 2021. The consolidated financial statements of the Company include all accounts of the Company, the GRT OP, and its subsidiaries. Intercompany transactions are not shown on the consolidated statements. However, each property-owning entity is a wholly-owned subsidiary which is a special purpose entity (“SPE”), whose assets and credit are not available to satisfy the debts or obligations of any other entity, except to the extent required with respect to any co-borrower or guarantor under the same credit facility. Use of Estimates The preparation of the unaudited consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the unaudited consolidated financial statements and accompanying notes. Actual results could materially differ from those estimates. Per Share Data The Company reports earnings per share for the period as (1) basic earnings per share computed by dividing net income (loss) attributable to common stockholders by the weighted average number of common shares outstanding during the period, and (2) diluted earnings per share computed by dividing net income (loss) attributable to common stockholders by the weighted average number of common shares outstanding, including common stock equivalents. Unvested RSUs that contain non-forfeitable rights to dividends are participating securities and are included in the computation of earnings per share pursuant to the two-class method. The effect of including unvested restricted stock units using the treasury stock method was excluded from our calculation of weighted average shares of common stock outstanding - diluted, as the inclusion would have been anti-dilutive for the nine months ended September 30, 2022 and 2021. Total excluded shares were 8,819,588 and 1,132,843 for the nine months ended September 30, 2022 and 2021, respectively. Segment Information ASC 280, Segment Reporting, establishes standards for reporting financial and descriptive information about a public entity’s reportable segments. The Company internally evaluates all of the properties and interests therein as one reportable segment. Change in Consolidated Financial Statements Presentation Certain amounts in the prior period consolidated financial statements have been reclassified to conform to the current period presentation. Interest rate swap assets have been reclassified from other assets to interest rate swap assets on the balance sheet for all periods presented. Income Taxes The Company has elected to be taxed as a REIT under the Internal Revenue Code (“Code”). To qualify as a REIT, the Company must meet certain organizational and operational requirements. The Company intends to adhere to these requirements and maintain its REIT status for the current year and subsequent years. As a REIT, the Company generally will not be subject to federal income taxes on taxable income that is distributed to stockholders. However, the Company may be subject to certain state and local taxes on its income and property, and federal income and excise taxes on its undistributed taxable income, if any. If the Company fails to qualify as a REIT in any taxable year, the Company will then be subject to federal income taxes on the taxable income at regular corporate rates and will not be permitted to qualify for treatment as a REIT for federal income tax purposes for four years following the year during which qualification is lost unless the Internal Revenue Service (“IRS”) grants the Company relief under certain statutory provisions. Such an event could materially adversely affect net income and net cash available for distribution to stockholders. As of September 30, 2022, the Company satisfied the REIT requirements and distributed all of its taxable income. Pursuant to the Code, the Company has elected to treat its corporate subsidiary as a taxable REIT subsidiary (a “TRS”). In general, the TRS may perform non-customary services for the Company’s tenants and may engage in any real estate or non-real estate-related business. The TRS will be subject to corporate federal and state income tax. Goodwill Goodwill represents the excess of consideration paid over the fair value of underlying identifiable net assets of business acquired. The Company's goodwill has an indeterminate life and is not amortized, but is tested for impairment on an annual basis, or more frequently if events or changes in circumstances indicate that the asset might be impaired. The Company takes a qualitative approach to consider whether an impairment of goodwill exists prior to quantitatively determining the fair value of the reporting unit in step one of the impairment test. The Company performs its annual assessment on October 1st. Recently Issued Accounting Pronouncements Changes to GAAP are established by the FASB in the form of ASUs to the FASB’s Accounting Standards Codification. The Company considers the applicability and impact of all ASUs. Other than the ASUs discussed below, the FASB has not recently issued any other ASUs that the Company expects to be applicable and have a material impact on the Company's financial statements.

Additionally, an ongoing replacement reserve is funded by certain tenants pursuant to each tenant’s respective lease as follows: Balance as of September 30, 2022 December 31, 2021 Cash reserves $ 10,502 $ 15,234 Restricted lockbox 1,543 2,288 Total $ 12,045 $ 17,522 Impairments During the nine months ended September 30, 2022, in connection with the preparation and review of the financial statements the Company recorded an impairment provision of approximately $86.3 million as it was determined that the carrying value of the real estate would not be recoverable on five properties located in the Midwest, Southwest and Southern region of the United States. This impairment resulted from a change in anticipated hold period and selling price. In determining the fair value of the properties, the Company considered Level 3 inputs. See Note 8, Fair Value Measurements, for details. Sale of Properties On August 26, 2022, the Company sold a 41-property office portfolio (the “Office Portfolio”) located across the continental United States. The sale price for the Office Portfolio was $1.1 billion, less closing costs and other closing credits. Upon the sale of the Office Portfolio, the Company recognized a loss of approximately $105.9 million. See Note 4, Investment in Unconsolidated Entities, for details. On September 23, 2022, the Company sold one property located in Phoenix, Arizona. The sale price for the property was $93.0 million, less closing costs and other closing credits. The Company recognized a gain of approximately $10.4 million.

Equity Method Investments and Joint Ventures [Abstract]
Investments in Unconsolidated Entities	Investments in Unconsolidated Entities Office Joint Venture The Company, through its subsidiary GRT VAO OP, LLC (“GRT VAO Sub”), owns indirectly an approximate 49% interest in the Office Portfolio, equal to approximately $159.9 million, through a joint venture (the “Office Joint Venture”). The Office Joint Venture is managed by RVMC Capital LLC, an affiliate of Workspace Property Trust (the “Managing Member”) and governed by a Joint Venture and Limited Liability Company Agreement dated as of August 26, 2022, by and between GRT VAO Sub and the Managing Member (the “JV Agreement”). The Managing Member of the Office Joint Venture has general authority to manage the operations of the Office Joint Venture. The Managing Member also has day-to-day management authority over the Office Joint Venture, subject to certain major decision rights held by the Office Joint Venture JV Partner. The Managing Member may be removed from its management positions upon the occurrence of specified “Cause Events” (as defined in the JV Agreement). GRT VAO Sub has approval rights over certain major decisions regarding actions by the Office Joint Venture, including certain fundamental decisions that the Office Joint Venture may approve. GRT VAO Sub’s obligation is generally limited to its initial contribution. GRT VAO Sub is not obligated to make any additional capital contributions beyond its initial capital contribution. The Office Joint Venture, through various subsidiary borrowers, obtained acquisition financing for the Office Portfolio comprised of (a) a $736.0 million mortgage loan (the “Mortgage Loan”), and (b) a $194.8 million mezzanine loan (the “Mezzanine Loan”, and together with the Mortgage Loan, the “Office JV Loans”). The initial maturity date of the Office JV Loans is September 9, 2023, subject to two, one-year extension options. The interest rates during the initial term of the Mortgage Loan and the Mezzanine Loan are Term SOFR (1-month) (with a 3% interest rate cap on SOFR) + 3.635% (subject to a 0.25% increase during each extension term) and Term SOFR (1-month) with a 3% interest rate cap on SOFR + 6.574% (subject to a 0.25% increase during each extension term), respectively. The Office Joint Venture paid $6.7 million for the interest rate caps. The Company has not guaranteed any debt obligations and has not otherwise committed to providing financial support in respect of the debt. In addition, the Company does not anticipate receiving any near-term cash flow distributions. Considering the Company’s limited economic exposure to the Office Joint Venture, the Company excludes interests in the assets in the Office Joint Venture from operating data. In connection with the Office JV Loans, GRT OP and GRT VAO Sub entered into a certain Put Agreement with JPMorgan Chase Bank, National Association (“JPM”), pursuant to which JPM had the right to put to GRT OP and GRT VAO Sub a portion of its interest in the Mezzanine Loan in the principal face amount of $39.3 million (the “Mezzanine Interest”). On September 29, 2022, JPM sold to GRT VAO Sub the Mezzanine Interest for approximately $34.4 million, which is included in the line item “Investments in unconsolidated entities” in the consolidated balance sheets. No gain or loss was recorded on the put purchase, as the purchase price was at fair value.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Interest Rate Contracts	Interest Rate Contracts Risk Management Objective of Using Derivatives The Company is exposed to certain risks arising from both business operations and economic conditions. The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of debt funding and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the payment of future known and uncertain cash amounts, the values of which are determined by expected cash payments principally related to borrowings and interest rates. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The Company does not use derivatives for trading or speculative purposes. Derivative Instruments The Company has entered into interest rate swap agreements to hedge the variable cash flows associated with certain existing or forecasted LIBOR based variable-rate debt, including the Company's KeyBank Loans. The change in the fair value of derivatives designated and qualifying as cash flow hedges is initially recorded in accumulated other comprehensive income (“AOCI”) and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. Amounts reported in AOCI related to derivatives will be reclassified to interest expense as interest payments are made on the Company's variable-rate debt. The following table sets forth a summary of the interest rate swaps at September 30, 2022 and December 31, 2021: Fair Value (1) Current Notional Amounts Derivative Instrument Effective Date Maturity Date Interest Strike Rate September 30, 2022 December 31, 2021 September 30, 2022 December 31, 2021 Assets/(Liabilities): Interest Rate Swap 3/10/2020 7/1/2025 0.83% $ 13,018 $ 1,648 $ 150,000 $ 150,000 Interest Rate Swap 3/10/2020 7/1/2025 0.84% 8,673 1,059 100,000 100,000 Interest Rate Swap 3/10/2020 7/1/2025 0.86% 6,453 749 75,000 75,000 Interest Rate Swap 7/1/2020 7/1/2025 2.82% 4,324 (7,342) 125,000 125,000 Interest Rate Swap 7/1/2020 7/1/2025 2.82% 3,428 (5,909) 100,000 100,000 Interest Rate Swap 7/1/2020 7/1/2025 2.83% 3,430 (5,899) 100,000 100,000 Interest Rate Swap 7/1/2020 7/1/2025 2.84% 3,398 (5,958) 100,000 100,000 Total $ 42,724 $ (21,652) $ 750,000 $ 750,000 (1) The Company records all derivative instruments on a gross basis in the consolidated balance sheets, and accordingly there are no offsetting amounts that net assets against liabilities. As of September 30, 2022, derivatives in an asset position are included in the line item “Interest rate swap asset” in the consolidated balance sheets at fair value. The LIBO rate as of September 30, 2022 (ef fe ctive dat e) was 2.57%. The following table sets forth the impact of the interest rate swaps on the consolidated statements of operations for the periods presented: Nine Months Ended September 30, 2022 2021 Interest Rate Swap in Cash Flow Hedging Relationship: Amount of gain recognized in AOCI on derivatives $ 59,179 $ 9,611 Amount of loss reclassified from AOCI into earnings under “Interest expense” $ (5,292) $ (10,655) Total interest expense presented in the consolidated statement of operations in which the effects of cash flow hedges are recorded $ 68,315 $ 63,662 During the twelve months subsequent to September 30, 2022, the Company estimates that an additional $17.6 million of its income will be recognized from AOCI into earnings. Certain agreements with the derivative counterparties contain a provision that if the Company defaults on any of its indebtedness, including a default where repayment of the indebtedness has not been accelerated by the lender within a specified time period, then the Company could also be declared in default on its derivative obligations. As of September 30, 2022, there were no swaps in a liability position. As of December 31, 2021, the fair value of interest rate swaps that were in a liability position, which excludes any adjustment for nonperformance risk related to these agreements, was approximately $25.1 million . As of September 30, 2022 and December 31, 2021, the Company had not posted any collateral related to these agreements.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The Company is required to disclose fair value information about all financial instruments, whether or not recognized in the consolidated balance sheets, for which it is practicable to estimate fair value. The Company measures and discloses the estimated fair value of financial assets and liabilities utilizing a fair value hierarchy that distinguishes between data obtained from sources independent of the reporting entity and the reporting entity’s own assumptions about market participant assumptions. This hierarchy consists of three broad levels, as follows: (i) quoted prices in active markets for identical assets or liabilities, (ii) “significant other observable inputs,” and (iii) “significant unobservable inputs.” “Significant other observable inputs” can include quoted prices for similar assets or liabilities in active markets, as well as inputs that are observable for the asset or liability, such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals. “Significant unobservable inputs” are typically based on an entity’s own assumptions, since there is little, if any, related market activity. In instances in which the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level of input that is significant to the fair value measurement in its entirety. The Company's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. There were no transfers between the levels in the fair value hierarchy during the nine months ended September 30, 2022 and the year ended December 31, 2021. The following table sets forth the assets and liabilities that the Company measures at fair value on a recurring basis by level within the fair value hierarchy as of September 30, 2022 and December 31, 2021: Assets/(Liabilities) Total Fair Value Quoted Prices in Active Markets for Identical Assets and Liabilities Significant Other Observable Inputs Significant Unobservable Inputs September 30, 2022 Interest Rate Swap Asset $ 42,724 $ — $ 42,724 $ — Corporate Owned Life Insurance Asset $ 6,035 $ — $ 6,035 $ — Mutual Funds Asset $ 5,082 $ 5,082 $ — $ — December 31, 2021 Interest Rate Swap Asset $ 3,456 $ — $ 3,456 $ — Interest Rate Swap Liability $ (25,108) $ — $ (25,108) $ — Corporate Owned Life Insurance Asset $ 6,875 $ — $ 6,875 $ — Mutual Funds Asset $ 5,543 $ 5,543 $ — $ — Real Estate As of September 30, 2022, in connection with the preparation and review of the Company's financial statements, the Company determined that four of the Company’s properties were impaired based upon discounted cash flow analyses where the most significant inputs were the market rental rates, terminal capitalization rate, discount rate and expected hold period; one additional property was impaired based on a shortened expected hold period and selling price. The Company considered these inputs as Level 3 measurements within the fair value hierarchy. The following table is a summary of the quantitative information related to the non-recurring fair value measurement for the impairment of the Company's real estate properties for the nine months ended September 30, 2022: Range of Inputs or Inputs Unobservable Inputs: Midwest Properties Southwest Property Market rent per square foot $8.50 to $12.75 $18.00 Terminal capitalization rate 9.50% to 11.25% 7.23% Discount rate 10.25% to 14.00% 8.60% Range of Inputs or Inputs Unobservable Inputs: Southern Property Expected selling price per square foot $295.96 Estimated hold period Less than one year Financial Instruments Disclosed at Fair Value Financial instruments as of September 30, 2022 and December 31, 2021 consisted of cash and cash equivalents, restricted cash, accounts receivable, accrued expenses and other liabilities, and mortgage payable and other borrowings, as defined in Note 5, Debt. With the exception of the mortgage loans in the table below, the amounts of the financial instruments presented in the consolidated financial statements substantially approximate their fair value as of September 30, 2022 and December 31, 2021. The fair value of the nine mortgage loans in the table below is estimated by discounting each loan’s principal balance over the remaining term of the mortgage using current borrowing rates available to the Company for debt instruments with similar terms and maturities. The Company determined that the mortgage debt valuation in its entirety is classified in Level 2 of the fair value hierarchy, as the fair value is based on current pricing for debt with similar terms as the in-place debt.

Equity [Abstract]
Equity	Equity Classes Class T shares, Class S shares, Class D shares, Class I shares, Class A shares, Class AA shares, Class AAA and Class E shares vote together as a single class, and each share is entitled to one vote on each matter submitted to a vote at a meeting of the Company's stockholders; provided that with respect to any matter that would only have a material adverse effect on the rights of a particular class of common stock, only the holders of such affected class are entitled to vote . The following table sets forth the classes of outstanding common stock as of September 30, 2022 and December 31, 2021. As of September 30, 2022 December 31, 2021 Class A 24,481,843 24,509,573 Class AA 47,522,112 47,592,118 Class AAA 926,936 926,936 Class D 42,013 42,013 Class E 248,621,352 249,088,676 Class I 1,911,731 1,911,731 Class S 1,800 1,800 Class T 559,115 565,265 Common Equity As of September 30, 2022, the Company had received aggregate gross offering proceeds of approximately $2.8 billion from the sale of shares in the private offering, the public offerings, the DRP offerings and mergers (includes EA-1 offerings and EA-1 merger with Signature Office REIT, Inc., the EA Mergers and the CCIT II Merger), as discussed in Note 1, Organization . As part of the $2.8 billion from the sale of shares, the Company issued approximately 43,772,611 shares of its common stock upon the consummation of the merger of Signature Office REIT, Inc. in June 2015 and 174,981,547 Class E shares (in exchange for all outstanding shares of EA-1's common stock at the time of the EA Mergers) in April 2019 upon the consummation of the EA Mergers and 93,457,668 Class E shares (in exchange for all the outstanding shares of CCIT II's common stock at the time of the CCIT II Merger). As of September 30, 2022, there were 324,066,902 shares outstanding, including shares issued pursuant to the DRP, less shares redeemed pursuant to the SRP and the self-tender offer, which occurred in May 2019. Distribution Reinvestment Plan (DRP) The Company has adopted the DRP, which allows stockholders to have dividends and other distributions otherwise distributable to them invested in additional shares of common stock. No sales commissions or dealer manager fees will be paid on shares sold through the DRP, but the DRP shares will be charged the applicable distribution fee payable with respect to all shares of the applicable class. The purchase price per share under the DRP is equal to the net asset value ("NAV") per share applicable to the class of shares purchased, calculated using the most recently published NAV available at the time of reinvestment. The Company may amend or terminate the DRP for any reason at any time upon 10 days' prior written notice to stockholders, which may be provided through the Company's filings with the SEC. On July 17, 2020, the Company filed a registration statement on Form S-3 for the registration of up to $100 million in shares pursuant to the Company's DRP (the “DRP Offering”). The DRP Offering may be terminated at any time upon 10 days’ prior written notice to stockholders. On October 1, 2021, the Board approved a suspension of the DRP, effective October 11, 2021. The following table summarizes the DRP offerings, by share class, as of September 30, 2022: Share Class Amount Shares Class A $ 9,687 1,052,170 Class AA 19,047 2,068,367 Class AAA 290 31,521 Class D 21 2,231 Class E 311,405 32,299,362 Class I 437 47,028 Class S — 12 Class T 177 19,090 Total $ 341,064 35,519,781 As of September 30, 2022 and September 30, 2021, the Company had issued approximately $341.1 million in shares pursuant to the DRP offerings. Share Redemption Program (SRP) The Company has adopted the SRP which enables stockholders to sell their common stock to the Company in limited circumstances. On October 1, 2021, the Company announced that it had suspended the SRP beginning with the next cycle, which commenced during fourth quarter 2021. On August 5 2022, the Company announced that it had amended and restated the SRP and that the SRP would resume August 5, 2022, with the applicable redemption date of September 30, 2022. As was the case prior to the SRP’s most recent suspension, the SRP continues to be available only for redemptions in connection with a holder’s death, disability or incompetence. The amended and restated SRP differs from the prior SRP in a number of respects, including, among other things, that the cap on quarterly redemptions is no longer tied to the NAV of shares issued under the DRP but rather is a dollar amount to be set by the Board and disclosed by the Company. Quarterly redemptions are capped at $5 million (or some other quarterly or annual amount determined by the Board and announced at least 10 business days before the applicable redemption date). In addition, during any calendar year, with respect to each share class, the Company may redeem no more than 5% of the weighted-average number of shares of such class outstanding during the prior calendar year. Under the SRP, the Company redeems shares as of the last business day of each quarter. The redemption price will is equal to the most recently published NAV per share for the applicable class prior to quarter end. Redemption requests must be received by 3:00 p.m. (Central time) one business day before on the last business day of the applicable quarter. Redemption requests exceeding the quarterly cap are filled on a pro rata basis, except that if pro rata redemption would result in a stockholder owning less than the minimum balance of $2,500 of shares of the Company's common stock, then the Company will redeem all of such stockholder’s shares. All unsatisfied redemption requests are treated as a request for redemption at the redemption date unless withdrawn by the stockholder. The following table summarizes share redemption (excluding the self-tender offer) activity during the three and nine months ended September 30, 2022 and 2021: Three Months Ended September 30, Nine Months Ended September 30, 2022 2021 2022 2021 Shares of common stock redeemed 673,649 588,662 673,649 2,232,476 Weighted average price per share $ 7.42 $ 9.09 $ 7.42 $ 9.03 During the three months ended September 30, 2022, the Company received requests for the redemption of common stock for approximately $5.4 million, which exceeded the quarterly limitation of $5.0 million. Since July 31, 2014 and through September 30, 2022, the Company had redeemed 28,978,578 shares (excluding the self-tender offer) of common stock for approximately $270.5 million at a weighted average price per share of $9.33 pursuant to the SRP. Issuance of Restricted Stock Units to Executive Officers, Employees and Directors The restricted stock units ("RSUs") granted since 2019 were pursuant to the Company’s Employee and Director Long-Term Incentive Plan (the “Plan”). The Plan provides for the grant of awards to the Company’s directors, full-time employees and certain consultants that provide services to the Company or affiliated entities. Awards granted under the Plan may consist of stock options, restricted stock, stock appreciation rights, distribution equivalent rights and other equity-based awards. The stock-based payments are measured at fair value and recognized as compensation expense over the vesting period. At the 2020 annual meeting of stockholders, stockholders approved an amended and restated Plan (the “Amended and Restated Plan”) that reduced the maximum number of shares authorized under the Plan to 7,000,000 shares, among other changes. Awards that vest or are granted on or after March 30, 2020 (the effective date of the Amended and Restated Plan) are subject to the terms and provisions of the Amended and Restated Plan. As of September 30, 2022 , approximately 5,494,646 shares were available for future issuance under the Amended and Restated Plan. On August 5, 2022, the Company issued 1,050,741 RSUs to employees, including officers, under the Amended and Restated Plan. The fair value of grants issued was approximately $7.8 million. As of September 30, 2022, there was $14.2 million of unrecognized compensation expense remaining, which vests between half a year and four years. Total share-based compensation expense for the three months ended September 30, 2022 and 2021 was approximately $2.7 million and $1.9 million, respectively. Compensation expense for nine months ended September 30, 2022 and 2021 was approximately $6.1 million and $5.7 million, respectively. The following table summarizes the activity of unvested shares of RSU awards for the periods presented: Number of Unvested Shares of RSU Awards Weighted-Average Grant Date Fair Value per Share Balance at December 31, 2020 943,836 Granted 1,619,255 $ 8.97 Forfeited (222,367) $ 9.10 Vested (812,111) $ 9.24 Balance at December 31, 2021 1,528,613 Granted 1,050,741 $ — Forfeited (68,743) $ 9.06 Vested (1) (128,235) $ 8.97 Balance at September 30, 2022 2,382,376

Noncontrolling Interests

Noncontrolling Interest [Abstract]
Noncontrolling Interests	Noncontrolling Interests Noncontrolling interests represent limited partnership interests in the GRT OP in which the Company is the general partner. General partnership units and limited partnership units of the GRT OP were issued as part of the initial capitalization of the GRT OP and GCEAR II Operating Partnership, in conjunction with members of management's contribution of certain assets, other contributions, and in connection with the self-administration transaction as discussed in Note 1, Organization. As of September 30, 2022, noncontrolling interests were approximately 9.0% of total shares and 8.8% of weighted average shares outstanding (both measures assuming GRT OP Units were converted to common stock). The Company has evaluated the terms of the limited partnership interests in the GRT OP, and as a result, has classified limited partnership interests issued in the initial capitalization, in conjunction with the contributed assets and in connection with the self-administration transaction, as noncontrolling interests, which are presented as a component of permanent equity, except as discussed below. The Company evaluates individual noncontrolling interests for the ability to recognize the noncontrolling interest as permanent equity on the consolidated balance sheets at the time such interests are issued and on a continual basis. Any noncontrolling interest that fails to qualify as permanent equity has been reclassified as temporary equity and adjusted to the greater of (a) the carrying amount or (b) its redemption value as of the end of the period in which the determination is made. As of September 30, 2022, the limited partners of the GRT OP owned approximately 31.8 million GRT OP Units, which were issued to affiliated parties and unaffiliated third parties in exchange for the contribution of certain properties to the Company, and in connection with the self-administration transaction and other services. In addition, 0.2 million GRT OP Units were issued to unaffiliated third parties unrelated to property contributions. To the extent the contributors should elect to redeem all or a portion of their GRT OP Units, pursuant to the terms of the respective contribution agreement, such redemption shall be at a per unit value equivalent to the price at which the contributor acquired its GRT OP Units in the respective transaction. The limited partners of the GRT OP, other than those related to the Will Partners REIT, LLC ("Will Partners") property contribution, will have the right to cause the general partner of the GRT OP, the Company, to redeem their GRT OP Units for cash equal to the value of an equivalent number of shares, or, at the Company’s option, purchase their GRT OP Units by issuing one share of the Company’s common stock for the original redemption value of each limited partnership unit redeemed. The Company has the control and ability to settle such requests in shares. These rights may not be exercised under certain circumstances which could cause the Company to lose its REIT election. The following summarizes the activity for noncontrolling interests recorded as equity for the nine months ended September 30, 2022 and year ended December 31, 2021: Nine Months Ended September 30, 2022 Year Ended December 31, 2021 Beginning balance $ 218,653 $ 226,550 Reclass of noncontrolling interest subject to redemption 956 (159) Distributions to noncontrolling interests (8,184) (10,942) Allocated distributions to noncontrolling interests subject to redemption (12) (18) Allocated net (loss) income (17,643) 66 Allocated other comprehensive income (loss) 5,666 3,156 Ending balance $ 199,436 $ 218,653 Noncontrolling interests subject to redemption Operating partnership units issued pursuant to the Will Partners property contribution are not included in permanent equity on the consolidated balance sheets. The partners holding these units can cause the general partner to redeem the units for the cash value, as defined in the GRT OP agreement. As the general partner does not control these redemptions, these units are presented on the consolidated balance sheets as noncontrolling interest subject to redemption at their redeemable value. The net income (loss) and distributions attributed to these limited partners is allocated proportionately between common stockholders and other noncontrolling interests that are not considered redeemable.

The terms of the Dealer Manager Agreement are substantially similar to the terms of the dealer manager agreement from the Company's initial public offering, except as it relates to the share classes offered and the fees to be received by the dealer manager. The Follow-On Offering terminated on September 20, 2020. See Note 9, Equity. Subject to the Financial Industry Regulatory Authority, Inc.'s limitations on underwriting compensation, under the Dealer Manager Agreement, the Company is required to pay to the dealer manager a distribution fee for ongoing services rendered to stockholders by participating broker-dealers or broker-dealers servicing investors’ accounts, referred to as servicing broker-dealers. The fee accrues daily, is paid monthly in arrears, and is calculated based on the average daily NAV for the applicable month. Conflicts of Interest Administrative Services Agreement In connection with EA-1’s self-administration transaction, the Company, GRT OP, L.P., Griffin Capital Essential Asset TRS, Inc, and Griffin Capital Real Estate Company, LLC, on the one hand, and GCC and Griffin Capital, LLC (“GC LLC”), on the other hand, entered into that certain Administrative Services Agreement dated December 14, 2018 (as amended, the “ASA”), pursuant to which GCC and GC LLC continue to provide certain operational and administrative services at cost to Company. The Company’s Executive Chairman is also the Chief Executive Officer of and controls GCC, which is the sole member of GC LLC. The Company pays GCC a monthly amount based on the actual costs anticipated to be incurred by GCC for the provision of such services until such items are terminated from the ASA. Such costs are reconciled periodically and a full review of the costs will be performed at least annually. In addition, the Company will directly pay or reimburse GCC for the actual cost of any reasonable third-party expenses incurred in connection with the provision of such services. On March 30, 2022 and June 30, 2022, the Company amended the ASA to reduce the scope of services provided, including removing the provision of office space and advisor services. Following such amendments, GCC and GC LLC are obligated to provide the Company with human resources support, and general corporate support on an as-needed basis. Office Sublease On March 25, 2022, the Company executed a sublease agreement with GCC (the “Sublease”) for the building located at 1520 E. Grand Ave, El Segundo, CA (the “Building”) which is the location of the Company’s corporate headquarters. The Building is part of a campus that contains other buildings and parking (the “Campus”). The Sublease also entitles the Company to use certain common areas on the Campus. Prior to the sublease agreement being signed, the rent for the office space was paid to GCC as part of the Administrative Services Agreement. The Campus is owned by GCPI, LLC (“GCPI”), and the Building is master leased by GCPI to GCC. GCC is the sublessor under the Sublease. The Company’s Executive Chairman is the Chief Executive Officer of and controls GCC and is also affiliated with GCPI. The Sublease provides for initial monthly base rent of $0.05 million, subject to annual escalations of 3% as well as additional rent for certain operating expenses for the Building and portions of the Campus. The Company’s Executive Chairman is the Chief Executive Officer of and controls GCC and is also affiliated with GCPI. Certain Conflict Resolution Procedures Every transaction that the Company enters into with affiliates is subject to an inherent conflict of interest. The Board may encounter conflicts of interest in enforcing the Company's rights against any affiliate in the event of a default by or disagreement with an affiliate or in invoking powers, rights or options pursuant to any agreement between the Company and affiliates. See the Company's Code of Ethics available at the “Governance Documents” subpage of the “Investors” section of the Company's website at www.grtreit.com for a detailed description of the Company's conflict resolution procedures.

Leases [Abstract]
Leases	Leases Lessor The Company leases commercial and industrial space to tenants primarily under non-cancelable operating leases that generally contain provisions for minimum base rents plus reimbursement for certain operating expenses. Total minimum lease payments are recognized in rental income on a straight-line basis over the term of the related lease and estimated reimbursements from tenants for real estate taxes, insurance, common area maintenance and other recoverable operating expenses are recognized in rental income in the period that the expenses are incurred. The Company recognized $277.7 million and $280.7 million of lease income related to operating lease payments for the nine months ended September 30, 2022 and 2021, respectively. The Company's current leases have expirations ranging from 2022 to 2044. The following table sets forth the undiscounted cash flows for future minimum base rents to be received under operating leases as of September 30, 2022: As of September 30, 2022 Remaining 2022 $ 64,680 2023 260,124 2024 246,214 2025 230,770 2026 219,626 Thereafter 983,351 Total $ 2,004,765 The future minimum base rents in the table above excludes tenant reimbursements of operating expenses, amortization of adjustments for deferred rent receivables and the amortization of above/below-market lease intangibles. Lessee Certain of the Company’s real estate are subject to ground leases. The Company’s ground leases are classified as either operating leases or financing leases based on the characteristics of each lease. As of September 30, 2022, the Company had five ground leases classified as operating and two ground leases classified as financing. Each of the Company’s ground leases were acquired as part of the acquisition of real estate and no incremental costs were incurred for such ground leases. The Company’s ground leases are non-cancelable, and contain no renewal options. The Company's Chicago office space lease has a remaining lease term of approximately three years and no option to renew. On March 25, 2022, the Company executed a sublease agreement with GCC for the building which is the Company’s corporate headquarters (See Note 11, Related Party Transactions, for details). The Company leases office space as part of conducting day-to-day business in El Segundo. The Company's office space lease has a remaining lease term of approximately two years and one option to renew for a period of five years. As of September 30, 2022, the Company recorded a lease liability and a right-of-use asset for approximately $1.0 million and is included in Right of Use Asset and Lease Liability on the Company’s consolidated balance sheet. The Company incurred operating lease costs of approximately $3.1 million for the nine months ended September 30, 2022 and $2.8 million for the nine months ended September 30, 2021, which are included in “Property Operating Expense” in the accompanying consolidated statement of operations. Total cash paid for amounts included in the measurement of operating lease liabilities was $1.6 million for the nine months ended September 30, 2022 and $1.2 million for the nine months ended September 30, 2021. The following table sets forth the weighted-average for the lease term and the discount rate as of September 30, 2022: As of September 30, 2022 Lease Term and Discount Rate Operating Financing Weighted-average remaining lease term in years 76 years 15 years Weighted-average discount rate (1) 4.86 % 3.26 % (1) Because the rate implicit in each of the Company's leases was not readily determinable, the Company used an incremental borrowing rate. In determining the Company's incremental borrowing rate for each lease, the Company considered recent rates on secured borrowings, observable risk-free interest rates and credit spreads correlating to the Company's creditworthiness, the impact of collateralization and the term of each of the Company's lease agreements. Maturities of lease liabilities as of September 30, 2022 were as follows: As of September 30, 2022 Operating Financing Remaining 2022 $ 534 $ 338 2023 2,151 355 2024 1,906 360 2025 1,567 365 2026 1,501 375 2026 1,524 381 Thereafter 250,233 3,458 Total undiscounted lease payments 259,416 5,632 Less: imputed interest (216,320) (2,130) Total lease liabilities $ 43,096 $ 3,502

In determining the Company's incremental borrowing rate for each lease, the Company considered recent rates on secured borrowings, observable risk-free interest rates and credit spreads correlating to the Company's creditworthiness, the impact of collateralization and the term of each of the Company's lease agreements. Maturities of lease liabilities as of September 30, 2022 were as follows: As of September 30, 2022 Operating Financing Remaining 2022 $ 534 $ 338 2023 2,151 355 2024 1,906 360 2025 1,567 365 2026 1,501 375 2026 1,524 381 Thereafter 250,233 3,458 Total undiscounted lease payments 259,416 5,632 Less: imputed interest (216,320) (2,130) Total lease liabilities $ 43,096 $ 3,502

Basis of Presentation and Sum_2

Basis of Presentation and Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2022
Accounting Policies [Abstract]
Basis of Accounting	The accompanying unaudited consolidated financial statements of the Company are prepared by management on the accrual basis of accounting and in accordance with generally accepted accounting principles in the United States (“GAAP”) for interim financial information as contained in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”), and in conjunction with rules and regulations of the SEC. Certain information and footnote disclosures required for annual financial statements have been condensed or excluded pursuant to SEC rules and regulations. Accordingly, the unaudited consolidated financial statements do not include all of the information and footnotes required by GAAP for complete financial statements.
Consolidation	The consolidated financial statements of the Company include all accounts of the Company, the GRT OP, and its subsidiaries. Intercompany transactions are not shown on the consolidated statements. However, each property-owning entity is a wholly-owned subsidiary which is a special purpose entity (“SPE”), whose assets and credit are not available to satisfy the debts or obligations of any other entity, except to the extent required with respect to any co-borrower or guarantor under the same credit facility.
Use of Estimates	The preparation of the unaudited consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the unaudited consolidated financial statements and accompanying notes. Actual results could materially differ from those estimates.
Per Share Data	The Company reports earnings per share for the period as (1) basic earnings per share computed by dividing net income (loss) attributable to common stockholders by the weighted average number of common shares outstanding during the period, and (2) diluted earnings per share computed by dividing net income (loss) attributable to common stockholders by the weighted average number of common shares outstanding, including common stock equivalents. Unvested RSUs that contain non-forfeitable rights to dividends are participating securities and are included in the computation of earnings per share pursuant to the two-class method. The effect of including unvested restricted stock units using the treasury stock method was excluded from our calculation of weighted average shares of common stock outstanding - diluted, as the inclusion would have been anti-dilutive for the nine months ended September 30, 2022 and 2021. Total excluded shares were 8,819,588 and 1,132,843 for the nine months ended September 30, 2022 and 2021, respectively.
Segment Information	ASC 280, Segment Reporting, establishes standards for reporting financial and descriptive information about a public entity’s reportable segments. The Company internally evaluates all of the properties and interests therein as one reportable segment.
Change in Consolidated Financial Statements Presentation	Certain amounts in the prior period consolidated financial statements have been reclassified to conform to the current period presentation. Interest rate swap assets have been reclassified from other assets to interest rate swap assets on the balance sheet for all periods presented.
Income Taxes	The Company has elected to be taxed as a REIT under the Internal Revenue Code (“Code”). To qualify as a REIT, the Company must meet certain organizational and operational requirements. The Company intends to adhere to these requirements and maintain its REIT status for the current year and subsequent years. As a REIT, the Company generally will not be subject to federal income taxes on taxable income that is distributed to stockholders. However, the Company may be subject to certain state and local taxes on its income and property, and federal income and excise taxes on its undistributed taxable income, if any. If the Company fails to qualify as a REIT in any taxable year, the Company will then be subject to federal income taxes on the taxable income at regular corporate rates and will not be permitted to qualify for treatment as a REIT for federal income tax purposes for four years following the year during which qualification is lost unless the Internal Revenue Service (“IRS”) grants the Company relief under certain statutory provisions. Such an event could materially adversely affect net income and net cash available for distribution to stockholders. As of September 30, 2022, the Company satisfied the REIT requirements and distributed all of its taxable income.Pursuant to the Code, the Company has elected to treat its corporate subsidiary as a taxable REIT subsidiary (a “TRS”). In general, the TRS may perform non-customary services for the Company’s tenants and may engage in any real estate or non-real estate-related business. The TRS will be subject to corporate federal and state income tax.
Goodwill	Goodwill represents the excess of consideration paid over the fair value of underlying identifiable net assets of business acquired. The Company's goodwill has an indeterminate life and is not amortized, but is tested for impairment on an annual basis, or more frequently if events or changes in circumstances indicate that the asset might be impaired. The Company takes a qualitative approach to consider whether an impairment of goodwill exists prior to quantitatively determining the fair value of the reporting unit in step one of the impairment test. The Company performs its annual assessment on October 1st.
Recently Issued Accounting Pronouncements and Adoption of New Accounting Pronouncements	Changes to GAAP are established by the FASB in the form of ASUs to the FASB’s Accounting Standards Codification. The Company considers the applicability and impact of all ASUs. Other than the ASUs discussed below, the FASB has not recently issued any other ASUs that the Company expects to be applicable and have a material impact on the Company's financial statements.
