Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization First Industrial Realty Trust, Inc. (the "Company") is a self-administered and fully integrated real estate company which owns, manages, acquires, sells, develops and redevelops industrial real estate. The Company is a Maryland corporation organized on August 10, 1993 and a real estate investment trust ("REIT") as defined in the Internal Revenue Code of 1986 (the "Code"). Unless stated otherwise or the context otherwise requires, the terms "we," "our" and "us" refer to the Company and its subsidiaries, including its operating partnership, First Industrial, L.P. (the "Operating Partnership"), and its consolidated subsidiaries. We began operations on July 1, 1994. The Company's operations are conducted primarily through the Operating Partnership, of which the Company is the sole general partner (the "General Partner"), with an approximate 97.7% ownership interest ("General Partner Units") at June 30, 2021. The Operating Partnership also conducts operations through several other limited partnerships (the "Other Real Estate Partnerships"), numerous limited liability companies ("LLCs") and certain taxable REIT subsidiaries ("TRSs"), the operating data of which, together with that of the Operating Partnership, is consolidated with that of the Company as presented herein. The Operating Partnership holds at least a 99% limited partnership interest in each of the Other Real Estate Partnerships. The general partners of the Other Real Estate Partnerships are separate corporations, wholly-owned by the Company, each with at least a .01% general partnership interest in the Other Real Estate Partnerships. The Company does not have any significant assets or liabilities other than its investment in the Operating Partnership and its 100% ownership interest in the general partners of the Other Real Estate Partnerships. The Company's noncontrolling interest in the Operating Partnership of approximately 2.3% at June 30, 2021 represents the aggregate partnership interest held by the limited partners thereof ("Limited Partner Units" and together with the General Partner Units, the "Units"). The limited partners of the Operating Partnership are persons or entities who contributed their direct or indirect interests in properties to the Operating Partnership in exchange for common Limited Partner Units of the Operating Partnership and/or recipients of RLP Units of the Operating Partnership (see Note 6) pursuant to the Company's stock incentive plan. We also own equity interests in, and provide various services to, two joint ventures (the "Joint Ventures") through a wholly-owned TRS of the Operating Partnership. The Joint Ventures are accounted for under the equity method of accounting. The operating data of the Joint Ventures is not consolidated with that of the Company or the Operating Partnership as presented herein. One of the Joint Ventures sold its remaining acres of land during the six months ended June 30, 2021. See Note 5 for more information related to the Joint Ventures. Profits, losses and distributions of the Operating Partnership, the LLCs, the Other Real Estate Partnerships, the TRSs and the Joint Ventures are allocated to the general partner and the limited partners, the members or the shareholders, as applicable, of such entities in accordance with the provisions contained within their respective organizational documents. As of June 30, 2021, we owned 427 industrial properties located in 20 states, containing an aggregate of approximately 61.8 million square feet of gross leasable area ("GLA"). Of the 427 properties owned on a consolidated basis, none of them are directly owned by the Company.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited interim consolidated financial statements have been prepared in accordance with the accounting policies described in the consolidated financial statements and related notes included in our annual report on Form 10-K for the year ended December 31, 2020 ("2020 Form 10-K") and should be read in conjunction with such consolidated financial statements and related notes. The 2020 year end consolidated balance sheet data included in this Form 10-Q filing was derived from the audited consolidated financial statements in our 2020 Form 10-K, but does not include all disclosures required by accounting principles generally accepted in the United States of America ("GAAP"). The following notes to these interim consolidated financial statements highlight significant changes to the notes included in the December 31, 2020 audited consolidated financial statements included in our 2020 Form 10-K and present interim disclosures as required by the Securities and Exchange Commission. Use of Estimates In order to conform with GAAP, in preparation of our consolidated financial statements we are required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of June 30, 2021 and December 31, 2020, and the reported amounts of revenues and expenses for the three and six months ended June 30, 2021 and 2020. Actual results could differ from those estimates. In our opinion, the accompanying unaudited interim consolidated financial statements reflect all adjustments necessary for a fair statement of our financial position as of June 30, 2021 and December 31, 2020, the results of our operations and comprehensive income for each of the three and six months ended June 30, 2021 and 2020, and our cash flows for each of the six months ended June 30, 2021 and 2020. All adjustments are of a normal recurring nature. Recent Accounting Pronouncements

Real Estate [Abstract]
Investment in Real Estate	Investment in Real Estate Acquisitions During the six months ended June 30, 2021, we acquired three industrial properties comprised of approximately 0.2 million square feet of GLA and five land parcels, one of which was acquired from our Joint Venture I (see Note 5). We accounted for the property and land parcels as asset acquisitions and therefore capitalized transaction costs to the basis of the acquired assets. The following table summarizes the allocation of the aggregate purchase price to each major asset class for the industrial properties and land parcels acquired during the six months ended June 30, 2021: Land $ 120,640 Building and Improvements/Construction in Progress 23,977 In-Place Leases 789 Other Assets 1,592 Total Purchase Price $ 146,998 The revenue and net income associated with the acquisition of the industrial properties and land parcels, since their respective acquisition dates, are not significant to the six months ended June 30, 2021. Real Estate Held for Sale As of June 30, 2021, we had four industrial properties and two industrial condominium units comprised of approximately 0.1 million square feet of GLA held for sale. Sales

See Note 10. (B) Amounts exclude unamortized debt issuance costs of $418 and $1,049 as of June 30, 2021 and December 31, 2020, respectively, which are included in the line item Prepaid Expenses and Other Assets, Net. (C) On July 7, 2021, we amended and restated our 2020 Unsecured Term Loan and our Unsecured Credit Facility. See Note 13 for additional information. Mortgage Loans Payable, Net During the six months ended June 30, 2021, we paid off mortgage loans in the amount of $57,912. As of June 30, 2021, mortgage loans payable are collateralized, and in some instances cross-collateralized, by industrial properties with a net carrying value of $137,238. We believe the Operating Partnership and the Company were in compliance with all covenants relating to mortgage loans as of June 30, 2021. Indebtedness The following is a schedule of the stated maturities and scheduled principal payments of our indebtedness, exclusive of premiums, discounts and debt issuance costs, for the next five years as of June 30, and thereafter: Amount Remainder of 2021 $ 261,579 2022 332,024 2023 321 2024 335 2025 349 Thereafter 1,007,865 Total $ 1,602,473 Our unsecured credit facility (the "Unsecured Credit Facility"), our unsecured term loans (the "Unsecured Term Loans"), our senior notes issued in private placements ("Private Placement Notes") and the indentures governing our senior unsecured notes contain certain financial covenants, including limitations on incurrence of debt and debt service coverage. Under the Unsecured Credit Facility and the Unsecured Term Loans an event of default can occur if the lenders, in their good faith judgment, determine that a material adverse change has occurred which could prevent timely repayment or materially impair our ability to perform our obligations under the loan agreements. We believe the Operating Partnership and the Company were in compliance with all covenants relating to the Unsecured Credit Facility, the Unsecured Term Loans, the Private Placement Notes and the indentures governing our senior unsecured notes as of June 30, 2021; however, these financial covenants are complex and there can be no assurance that these provisions would not be interpreted by our lenders and noteholders in a manner that could impose and cause us to incur material costs. Fair Value At June 30, 2021 and December 31, 2020, the fair value of our indebtedness was as follows: June 30, 2021 December 31, 2020 Carrying Amount (A) Fair Carrying Amount (A) Fair Mortgage Loans Payable, Net $ 83,902 $ 86,609 $ 144,214 $ 148,770 Senior Unsecured Notes, Net 998,509 1,084,772 998,506 1,096,262 Unsecured Term Loans 460,000 460,916 460,000 458,207 Unsecured Credit Facility 60,000 60,065 — — Total $ 1,602,411 $ 1,692,362 $ 1,602,720 $ 1,703,239 _______________ (A) The carrying amounts include unamortized premiums and discounts and exclude unamortized debt issuance costs. The fair values of our mortgage loans payable were determined by discounting the future cash flows using the current rates at which similar loans would be made based upon similar remaining maturities. The current market rates we utilized were internally estimated. The fair value of the senior unsecured notes were determined by using rates, as advised by our bankers, that are based upon recent trades within the same series of the senior unsecured notes, recent trades for senior unsecured notes with comparable maturities, recent trades for fixed rate unsecured notes from companies with profiles similar to ours, as well as overall economic conditions. The fair value of the Unsecured Term Loans was determined by discounting the future cash flows using current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining term, assuming no repayment until maturity. We have concluded that our determination of fair value for each of our mortgage loans payable, senior unsecured notes and the Unsecured Term Loans was primarily based upon Level 3 inputs.

Variable Interest Entities [Abstract]
Variable Interest Entities	Variable Interest Entities Other Real Estate Partnerships The Other Real Estate Partnerships are variable interest entities ("VIEs") of the Operating Partnership and the Operating Partnership is the primary beneficiary, thus causing the Other Real Estate Partnerships to be consolidated by the Operating Partnership. In addition, the Operating Partnership is a VIE of the Company and the Company is the primary beneficiary. The following table summarizes the assets and liabilities of the Other Real Estate Partnerships included in our consolidated balance sheets, net of intercompany amounts: June 30, 2021 December 31, 2020 ASSETS Assets: Net Investment in Real Estate $ 259,093 $ 245,396 Operating Lease Right-of-Use Assets 13,130 13,173 Cash and Cash Equivalents 3,634 4,090 Deferred Rent Receivable 10,527 9,219 Prepaid Expenses and Other Assets, Net 9,266 8,077 Total Assets $ 295,650 $ 279,955 LIABILITIES AND PARTNERS' CAPITAL Liabilities: Mortgage Loans Payable, Net $ 2,487 $ 6,292 Accounts Payable, Accrued Expenses and Other Liabilities 9,527 10,067 Operating Lease Liabilities 10,291 10,304 Rents Received in Advance and Security Deposits 3,730 4,130 Partners' Capital 269,615 249,162 Total Liabilities and Partners' Capital $ 295,650 $ 279,955 Joint Ventures Through a wholly-owned TRS of the Operating Partnership, we own a 49% interest in a joint venture ("Joint Venture I") and a 43% interest in another joint venture ("Joint Venture II", together with Joint Venture I, the "Joint Ventures"). The Joint Ventures were both formed for the purpose of developing, leasing, operating and selling land located in the Phoenix, Arizona metropolitan area. During the six months ended June 30, 2021, Joint Venture I sold its remaining acres of land and liquidated the venture. Under the operating agreements for each of the Joint Ventures, we act as the managing member and are entitled to receive fees for providing management, leasing, development, construction supervision, disposition and asset management services. In addition, both of the Joint Ventures' operating agreements provide us the ability to earn incentive fees based on the ultimate financial performance of each of the Joint Ventures. During the six months ended June 30, 2021 and 2020, we earned fees of $276 and $335, respectively, from the Joint Ventures related to asset management and development services we provided to the Joint Ventures, of which we deferred recognition of $47 and $148, respectively, due to our economic interest in the Joint Ventures. At June 30, 2021, we had an aggregate receivable from the Joint Ventures of $55. Net income of the Joint Ventures for the six months ended June 30, 2021 and 2020 was $14,905 and $45, respectively. Included in net income during the six months ended June 30, 2021 is gain on sale of real estate of $15,028 related to the sale of 138 net developable acres of land for which our economic share of the gain on sale, inclusive of incentive fees, is $10,166. However, since the Company was the purchaser of the 138 net developable acres from Joint Venture I, we netted our portion of gain on sale and incentive fees against the basis of the land acquired.

Stockholders' Equity Note [Abstract]
Stockholders' Equity of the Company and Partners' Capital of the Operating Partnership	Equity of the Company and Partners' Capital of the Operating Partnership Noncontrolling Interest of the Company The equity positions of various individuals and entities that contributed their properties to the Operating Partnership in exchange for Limited Partner Units, as well as the equity positions of the holders of Limited Partner Units issued in connection with the grant of restricted limited partner Units ("RLP Units") pursuant to the Company's stock incentive plan, are collectively referred to as the “Noncontrolling Interests.” An RLP Unit is a class of limited partnership interest of the Operating Partnership that is structured as a “profits interest” for U.S. federal income tax purposes and is an award that is granted under our stock incentive plan (see Note 9). Generally, RLP Units entitle the holder to receive distributions from the Operating Partnership that are equivalent to the dividends and distributions that would be made with respect to the number of shares of Common Stock underlying such RLP Units, though receipt of such distributions may be delayed or made contingent on vesting. Once an RLP Unit has vested and received allocations of book income sufficient to increase the book capital account balance associated with such RLP Unit (which will initially be zero) equal to, on a per-unit basis, the book capital account balance associated with a "common" Limited Partner Unit of the Operating Partnership, it automatically becomes a common Limited Partner Unit that is convertible by the holder to one share of Common Stock or a cash equivalent, at the Company's option. Net income is allocated to the Noncontrolling Interests based on the weighted average ownership percentage during the period. Noncontrolling Interest - Joint Venture II

Share-based Payment Arrangement, Noncash Expense [Abstract]
Long-Term Compensation	Long-Term Compensation Awards with Performance Measures During the six months ended June 30, 2021, 58,568 performance units ("Performance Units") and 263,621 RLP Units ("Performance RLP Units" and, together with the Performance Units, collectively the "Performance Awards") were granted to certain employees based on performance-based criteria, which had a fair value of approximately $7,162 on the grant date as determined by a lattice-binomial option-pricing model based on a Monte Carlo simulation. A portion of each Performance Award vests based upon the total shareholder return ("TSR") of the Company's common stock compared to the TSR of the FTSE Nareit All Equity Index and the remainder vests based upon the TSR of the Company’s common stock compared to nine other peer industrial real estate companies. The performance period for these Performance Awards is three years. Compensation expense is charged to earnings over the applicable vesting period for the Performance Awards. At the end of the measuring period, vested Performance Units convert into shares of common stock. Service Based Awards For the six months ended June 30, 2021, 67,127 shares of restricted stock units ("Service Units") and 51,525 RLP Units ("Service RLP Units" and together with the Service Units, collectively the "Service Awards") were granted to certain employees and outside directors based on service-based criteria, which had an aggregate fair value of approximately $5,195 on the grant date. The Service Awards granted to employees generally vest ratably over three years based on continued employment. Service Awards granted to outside directors vest after one year. Compensation expense is charged to earnings over the vesting periods for the Service Awards. At the end of the service period, vested Service Units convert into shares of common stock. Retirement Eligibility Commencing January 1, 2020, all award agreements issued underlying Performance Awards and Service Awards contain a retirement benefit for employees with at least 10 years of continuous service and are at least 60 years old. For employees that meet the age and service eligibility requirements, their awards are non -forfeitab le. As such, during the six months ended June 30, 2021, we expensed 100% of the awards granted to retirement-eligible employees at the grant date as if fully vested. For employees who will meet the age and service eligibility requirements during the normal vesting periods, the grants are amortized over the shorter service period. Outstanding Performance Awards and Service Awards We recognized $3,451 and $3,108 for the three months ended June 30, 2021 and 2020, respectively, and $7,064 and $6,749 for the six months ended June 30, 2021 and 2020, respectively, in compensation expense related to the amortization of the Service Awards and the Performance Awards. Service Award and Performance Award amortization capitalized in connection with development activities was $507 and $330 for the three months ended June 30, 2021 and 2020, respectively, and $1,210 and $1,312 for the six months ended June 30, 2021 and 2020, respectively. At June 30, 2021, we had $17,776 in unrecognized compensation related to unvested Service Awards and Performance Awards. The weighted average period that the unrecognized compensation is expected to be recognized is 0.91 years.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivatives Our objectives in using derivatives are to add stability to interest expense and to manage our cash flow volatility and exposure to interest rate movements. To accomplish these objectives, we primarily use derivative instruments as part of our interest rate risk management strategy. Derivative instruments designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. In connection with the origination of each Unsecured Term Loan (see Note 4), we entered into interest rate swaps to manage our exposure to changes in the one-month LIBOR rate. We have six interest rate swaps, with an aggregate notional value of $260,000, that fix the one-month LIBOR rate at a weighted average rate of 1.79% and mature on September 12, 2022 (the "2015 Swaps") and three interest rate swaps with an aggregate notional value of $200,000, that fix the one-month LIBOR rate at 0.99% that commenced February 1, 2021 and mature on February 2, 2026 (the "2021 Swaps"). We also had four interest rate swaps, with an aggregate notional value of $200,000, that fixed the one-month LIBOR rate at a weighted average rate of 2.29% and matured on January 29, 2021 (the "2014 Swaps"). We designated the 2014 Swaps, the 2015 Swaps and the 2021 Swaps as cash flow hedges. Additionally, during the six months ended June 30, 2020, we entered into an interest rate swap to manage our exposure to changes in the one-month LIBOR rate related to our Unsecured Credit Facility (the "2020 Swap"). The 2020 Swap commenced April 1, 2020, matured on April 1, 2021, had a notional value of $150,000 and fixed the one-month LIBOR rate at 0.42%. Our agreements with our derivative counterparties contain certain cross-default provisions that may be triggered in the event that our other indebtedness is in default, subject to certain thresholds. As of June 30, 2021, we had not posted any collateral related to these agreements and were not in breach of any of the provisions of these agreements. If we had breached these agreements, we could have been required to settle our obligations under the agreements at their termination value. The following table sets forth our financial liabilities related to the 2014 Swaps, the 2015 Swaps, the 2020 Swap and the 2021 Swaps which are included in the line items Accounts Payable, Accrued Expenses and Other Liabilities and are accounted for at fair value on a recurring basis as of June 30, 2021 and December 31, 2020: Fair Value Measurements: Description Fair Value at June 30, 2021 Quoted Prices in Significant Other Unobservable Derivatives designated as a hedging instrument: Liabilities: 2015 Swaps $ (5,167) — $ (5,167) — 2021 Swaps $ (1,885) — $ (1,885) — Fair Value at December 31, 2020 Derivatives designated as a hedging instrument: Liabilities: 2014 Swaps $ (333) — $ (333) — 2015 Swaps $ (7,317) — $ (7,317) — 2021 Swaps $ (6,244) — $ (6,244) — Derivatives not designated as a hedging instrument: Liabilities: 2020 Swap $ (106) — $ (106) — There was no ineffectiveness recorded on the 2014 Swaps, 2015 Swaps or the 2021 Swaps during the six months ended June 30, 2021. See Note 7 for more information regarding our derivatives. The estimated fair value of the 2014 Swaps, the 2015 Swaps, the 2020 Swap and the 2021 Swaps was determined using the market standard methodology of netting the discounted fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts are based on an expectation of interest rates (forward curves) derived from observable market interest rate curves. In addition, credit valuation adjustments are incorporated in the fair value to account for potential non-performance risk, including our own non-performance risk and the respective counterparty's non-performance risk. We determined that the significant inputs used to value the 2014 Swaps, the 2015 Swaps, the 2020 Swap and the 2021 Swaps fell within Level 2 of the fair value hierarchy.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies In the normal course of business, we are involved in legal actions arising from the ownership of our industrial properties. In our opinion, the liabilities, if any, that may ultimately result from such legal actions are not expected to have a materially adverse effect on our consolidated financial position, operations or liquidity. In conjunction with the development of industrial properties, we have entered into agreements with general contractors for the construction of industrial properties. At June 30, 2021, we had 13 industrial properties totaling approximately 5.0 million square feet of GLA under construction. The estimated total investment as of June 30, 2021 is approximately $500,900. Of this amount, approximately $300,500 remains to be funded. There can be no assurance that the actual completion cost will not exceed the estimated total investment.

Subsequent Events	Subsequent Events From July 1, 2021 to July 23, 2021, we acquired one land parcel for a purchase price of $26,565, excluding transaction costs. On July 7, 2021, we amended and restated our Unsecured Credit Facility to, among other things, extend the maturity date and increase the borrowing capacity thereunder to $750,000 (as amended and restated, the "New Credit Facility"). The New Credit Facility provides for interest-only payments initially at LIBOR plus 77.5 basis points and a facility fee of 15 basis points. The interest rate and facility fee are each subject to adjustment based on our leverage and investment grade rating. The New Credit Facility matures on July 7, 2025, unless extended at our option pursuant to two six-month extension options, subject to certain conditions. We may request the borrowing capacity under the New Credit Facility to be increased to $1,000,000, subject to certain restrictions.

Accounting Policies [Abstract]
Basis of Presentation	Basis of PresentationThe accompanying unaudited interim consolidated financial statements have been prepared in accordance with the accounting policies described in the consolidated financial statements and related notes included in our annual report on Form 10-K for the year ended December 31, 2020 ("2020 Form 10-K") and should be read in conjunction with such consolidated financial statements and related notes. The 2020 year end consolidated balance sheet data included in this Form 10-Q filing was derived from the audited consolidated financial statements in our 2020 Form 10-K, but does not include all disclosures required by accounting principles generally accepted in the United States of America ("GAAP"). The following notes to these interim consolidated financial statements highlight significant changes to the notes included in the December 31, 2020 audited consolidated financial statements included in our 2020 Form 10-K and present interim disclosures as required by the Securities and Exchange Commission.
Use of Estimates	Use of Estimates In order to conform with GAAP, in preparation of our consolidated financial statements we are required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of June 30, 2021 and December 31, 2020, and the reported amounts of revenues and expenses for the three and six months ended June 30, 2021 and 2020. Actual results could differ from those estimates. In our opinion, the accompanying unaudited interim consolidated financial statements reflect all adjustments necessary for a fair statement of our financial position as of June 30, 2021 and December 31, 2020, the results of our operations and comprehensive income for each of the three and six months ended June 30, 2021 and 2020, and our cash flows for each of the six months ended June 30, 2021 and 2020. All adjustments are of a normal recurring nature.
Recent Accounting Pronouncements	Recent Accounting PronouncementsIn March 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU”) No. 2020-04 Reference Rate Reform (Topic 848). ASU 2020-04 contains practical expedients for reference rate reform-related activities that impact debt, leases, derivatives and other contracts. The guidance in ASU 2020-04 is optional and may be elected over time as reference rate reform activities occur. The Company elected to apply the hedge accounting expedients related to probability and the assessments of effectiveness for future LIBOR-indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives. Application of these expedients preserves the presentation of derivatives consistent with past presentation. The Company continues to evaluate the impact of the guidance and may apply other elections as applicable as additional changes in the market occur.
