Accounting Policies [Abstract]
Consolidation and Investments in Joint Ventures	Consolidation and Investments in Joint Ventures The accompanying financial statements are presented on a consolidated basis and include all accounts of the Parent Company, the Operating Partnership, the taxable REIT subsidiaries (“TRSs”) of the Operating Partnership, subsidiaries of the Operating Partnership that are controlled, and any variable interest entities (“VIEs”) in which the Operating Partnership is the primary beneficiary. As of March 31, 2025, we owned investments in two consolidated joint ventures that were VIEs in which the partners did not have substantive participating rights, and we were the primary beneficiary. As of March 31, 2025, these consolidated VIEs had mortgage debt totaling $109.1 million, which was secured by assets of the VIEs totaling $218.9 million. The Operating Partnership guarantees the mortgage debt of these VIEs. The Operating Partnership is considered a VIE as the limited partners do not hold kick-out rights or substantive participating rights. The Parent Company consolidates the Operating Partnership as it is the primary beneficiary. As of March 31, 2025, the Company also owned investments in four unconsolidated joint ventures accounted for under the equity method, which are not considered VIEs. On January 31, 2024, the joint venture that owned Glendale Center Apartments, of which we have an 11.5% ownership interest, sold the 267-unit property to a third party, resulting in a gain on sale of $20.2 million. The Company recognized its share of the gain on sale of unconsolidated property of $2.3 million during the three months ended March 31, 2024. In addition, the Company received a $1.6 million distribution upon the disposition of the property during the three months ended March 31, 2024. The Company maintains an investment in the joint venture, which is in the process of winding up its activities and distributing remaining net assets. Glendale Center Apartments is adjacent to our Glendale Town Center operating retail property in the Indianapolis MSA.
Income Taxes and REIT Compliance	Income Taxes and REIT Compliance Parent Company The Parent Company has been organized and operated, and intends to continue to operate, in a manner that will enable it to maintain its qualification as a REIT for U.S. federal income tax purposes. As a result, it generally will not be subject to U.S. federal income tax on the earnings that it distributes to the extent it distributes its “REIT taxable income” (determined before the deduction for dividends paid and excluding net capital gains) to shareholders of the Parent Company and meets certain other requirements on a recurring basis. To the extent that it satisfies this distribution requirement but distributes less than 100% of its taxable income, it will be subject to U.S. federal income tax on its undistributed REIT taxable income at regular corporate income tax rates. REITs are subject to a number of organizational and operational requirements. If the Parent Company fails to qualify as a REIT in any taxable year, it will be subject to U.S. federal income tax on its taxable income at regular corporate income tax rates for a period of four years following the year in which qualification is lost. Additionally, we may also be subject to certain taxes enacted by the Inflation Reduction Act of 2022 that are applicable to non-REIT corporations, including the nondeductible 1% excise tax on certain stock repurchases. We may also be subject to certain U.S. federal, state, and local taxes on our income and property and to U.S. federal income and excise taxes on our undistributed taxable income even if the Parent Company does qualify as a REIT. The Operating Partnership intends to continue to make distributions to the Parent Company in amounts sufficient to assist the Parent Company in adhering to REIT requirements and maintaining its REIT status. We have elected to treat Kite Realty Holdings, LLC and IWR Protective Corporation as TRSs of the Operating Partnership, and we may elect to treat other subsidiaries as TRSs in the future. This election enables us to receive income and provide services that would otherwise be impermissible for a REIT. Deferred tax assets and liabilities are established for temporary differences between the financial reporting bases and the tax bases of assets and liabilities at the tax rates expected to be in effect when the temporary differences reverse. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that some portion or all of the deferred tax asset will not be realized. Operating Partnership The allocated share of income and loss, other than the operations of our TRSs, is included in the income tax returns of the Operating Partnership’s partners. Accordingly, the only U.S. federal income taxes included in the accompanying consolidated financial statements are in connection with the TRSs.
Noncontrolling Interests	Noncontrolling Interests We report the non-redeemable noncontrolling interests in subsidiaries as equity, and the amount of consolidated net income attributable to these noncontrolling interests is set forth separately in the accompanying consolidated financial statements. Noncontrolling Interests – Joint Venture Prior to the merger with Retail Properties of America, Inc. (“RPAI”) in October 2021, RPAI entered into a joint venture related to the development, ownership and operation of the multifamily rental portion of the expansion project at One Loudoun Downtown – Pads G & H. The Company owns 90% of the joint venture. Under terms defined in the joint venture agreement, after construction completion and stabilization of the development project (as defined in the joint venture agreement), the Company has the ability to call, and the joint venture partner has the ability to put to the Company, subject to certain conditions, the joint venture partner’s interest in the joint venture at fair value. As of March 31, 2025, the conditions for exercising the put and call options have been met but neither the Company nor the joint venture partner has exercised their respective options. The joint venture is considered a VIE primarily because the Company’s joint venture partner does not have substantive kick-out rights or substantive participating rights. The Company is considered the primary beneficiary as it has a controlling financial interest in the joint venture. As such, the Company has consolidated this joint venture and presented the joint venture partner’s interests as noncontrolling interests. Redeemable Noncontrolling Interests – Limited Partners Limited Partner Units are redeemable noncontrolling interests in the Operating Partnership. We classify redeemable noncontrolling interests in the Operating Partnership in the accompanying consolidated balance sheets outside of permanent equity because we may be required to pay cash to holders of Limited Partner Units upon redemption of their interests in the Operating Partnership or deliver registered shares upon their conversion. The carrying amount of the redeemable noncontrolling interests in the Operating Partnership is reflected at the greater of historical book value or redemption value with a corresponding adjustment to additional paid-in capital. As of March 31, 2025 and December 31, 2024, the redemption value of the redeemable noncontrolling interests in the Operating Partnership exceeded the historical book value, and the balances were accordingly adjusted to redemption value. We allocate net operating results of the Operating Partnership after noncontrolling interests in the consolidated properties based on the partners’ respective weighted average ownership interest. We adjust the redeemable noncontrolling interests in the Operating Partnership at the end of each reporting period to reflect their interests in the Operating Partnership or redemption value. This adjustment is reflected in our shareholders’ and Parent Company’s equity. As of March 31, 2025, the Parent Company’s interest and the limited partners’ redeemable noncontrolling ownership interests in the Operating Partnership were 97.8% and 2.2%, respectively. As of December 31, 2024, the Parent Company’s interest and the limited partners’ redeemable noncontrolling ownership interests in the Operating Partnership were 98.1% and 1.9%, respectively. Concurrent with the Parent Company’s IPO and related formation transactions, certain individuals received Limited Partner Units of the Operating Partnership in exchange for their interests in certain properties. The limited partners have the right to redeem Limited Partner Units for cash or, at the Parent Company’s election, common shares of the Parent Company in an amount equal to the market value of an equivalent number of common shares of the Parent Company at the time of redemption. Such common shares must be registered, which is not fully in the Parent Company’s control. Therefore, the limited partners’ interest is not reflected within permanent equity. The Parent Company also has the right to redeem the Limited Partner Units directly from the limited partner in exchange for either cash in the amount specified above or a number of its common shares equal to the number of Limited Partner Units being redeemed. There were 4,849,588 and 4,192,597 Limited Partner Units outstanding as of March 31, 2025 and December 31, 2024, respectively. The increase in Limited Partner Units outstanding from December 31, 2024 is due to non-cash compensation awards granted to our executive officers in the form of Limited Partner Units.
Fair Value Measurements	Fair Value Measurements We follow the framework established under Financial Accounting Standards Board Accounting Standards Codification (“ASC”) 820, Fair Value Measurements and Disclosures, for measuring fair value of non-financial assets and liabilities that are not required or permitted to be measured at fair value on a recurring basis but only in certain circumstances, such as a business combination or upon determination of an impairment. Assets and liabilities recorded at fair value in the accompanying consolidated balance sheets are categorized based on the inputs to the valuation techniques as follows: •Level 1 fair value inputs are quoted prices in active markets for identical instruments to which we have access. •Level 2 fair value inputs are inputs other than quoted prices included in Level 1 that are observable for similar instruments, either directly or indirectly, and appropriately consider counterparty creditworthiness in the valuation. •Level 3 fair value inputs reflect our best estimate of inputs and assumptions market participants would use in pricing an instrument at the measurement date. The inputs are unobservable in the market and significant to the valuation estimate. In instances where the determination of the fair value measurement is based upon 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 input that is significant to the fair value measurement in its entirety. Our 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.
New Accounting Pronouncements	New Accounting Pronouncements In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. This new guidance requires public entities to disclose, in a tabular format, the amounts of certain natural expenses included within relevant expense captions presented on the face of the income statement, as well as provide additional disclosures about selling expenses. The new disclosure requirements are effective for annual reporting periods beginning after December 15, 2026 and interim periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted, and may be applied either prospectively or retrospectively. The Company is currently evaluating the impact of this guidance on its consolidated financial statements and related disclosures.
