Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Organization, Ownership, and Basis of Presentation | Organization, Ownership, and Basis of Presentation Kilroy Realty Corporation (the “Company”) is a self-administered real estate investment trust (“REIT”) active in premier office, life science, and mixed-use property types in the United States. The Company’s approach to modern business environments is designed to drive creativity and productivity for some of the world’s leading technology, entertainment, life science, and business services companies and we have been consistently recognized for our leadership in sustainability and building operations. The Company owns, develops, acquires, and manages real estate assets consisting primarily of premier properties in Los Angeles, San Diego, the San Francisco Bay Area, Seattle, and Austin, which are markets we believe have strategic advantages and strong barriers to entry. The Company qualifies as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”). The Company’s common stock is publicly traded on the New York Stock Exchange (“NYSE”) under the ticker symbol “KRC.” We own our interests in all of our real estate assets through Kilroy Realty, L.P. (the “Operating Partnership”) and conduct substantially all of our operations through the Operating Partnership. Unless stated otherwise or the context otherwise requires, the terms “Kilroy Realty Corporation” or the “Company,” “we,” “our,” and “us” refer to Kilroy Realty Corporation and its consolidated subsidiaries, including the Operating Partnership, and the term “Operating Partnership” refers to Kilroy Realty, L.P. and its consolidated subsidiaries. The descriptions of our business, employees, and properties apply to both the Company and the Operating Partnership. Our stabilized portfolio includes all of our properties with the exception of development and redevelopment properties currently committed for construction, under construction, or in the tenant improvement phase, undeveloped land, and real estate assets held for sale, if any. We define redevelopment properties as those properties for which we expect to spend significant development and construction costs pursuant to a formal plan to change its use, the intended result of which is a higher economic return on the property. We define a property in the tenant improvement phase as a development or redevelopment property where the project has reached “cold shell condition” and is ready for tenant improvements, which may require additional major base building modifications before being placed in service. Projects in the tenant improvement phase are moved into our stabilized portfolio once the project reaches the earlier of 95% occupancy or one year from the date of the cessation of major base building construction activities. Costs capitalized to construction in progress for development and redevelopment properties are transferred to land and improvements, buildings and improvements, and deferred leasing costs on our consolidated balance sheets as the projects or phases of projects are placed in service. We did not have any properties or undeveloped land held for sale at March 31, 2025. Our stabilized portfolio of operating properties was comprised of the following properties at March 31, 2025:
| Number of Buildings |  | Rentable Square Feet |  | Number of Tenants |  | Percentage Occupied (1) |  |
Stabilized Office Properties (2) | 123 |  |  | 17,135,817 |  |  | 432 |  |  | 81.4 | % |  |
________________________ (1)Represents economic occupancy for space where we have achieved revenue recognition for the associated lease agreements. (2)Includes stabilized life science and retail space.
| Number of Properties |  | Number of Units |  | 2025 Average Occupancy
Stabilized Residential Properties | 3 |  |  | 1,001 |  |  | 95.2 | %
As of March 31, 2025, the following development and redevelopment properties were excluded from our stabilized portfolio:
| Number of Properties/Projects |  | Estimated Rentable Square Feet (1)
In-process development projects - tenant improvement | 1 |  | 875,000 |
In-process redevelopment projects - tenant improvement | 2 |  | 100,000 |
________________________ (1)Estimated rentable square feet upon completion. Our stabilized portfolio excludes our future development pipeline, which, as of March 31, 2025, was comprised of eight future development sites, representing approximately 64 gross acres of undeveloped land. As of March 31, 2025, all of our properties and development and redevelopment projects, and all of our business was conducted in the state of California, with the exception of ten stabilized office properties and one future development project located in the state of Washington, and one stabilized office property and one future development project located in Austin, Texas. All of our properties, and development and redevelopment projects are 100% owned, excluding the following four office properties owned by the following three consolidated property partnerships:
Consolidated Property Partnership |  | Property Address |  | Ownership Interest (1)
100 First Street Member, LLC |  | 100 1st Street, San Francisco, CA 94105 |  | 56%
303 Second Street Member, LLC |  | 303 2nd Street, San Francisco, CA 94107 |  | 56%
Redwood City Partners, LLC |  | 900 Jefferson Avenue, Redwood City, CA 94063 |  | 93%
|  | 900 Middlefield Road, Redwood City, CA 94063 |  |
________________________ (1)The remaining interests in all three property partnerships were owned by unrelated third parties. The consolidated financial statements of the Company include the consolidated financial position and results of operations of the Company, the Operating Partnership, 100 First Street Member, LLC (“100 First LLC”), 303 Second Street Member, LLC (“303 Second LLC”), Redwood City Partners, LLC (“Redwood LLC”), and all of our wholly-owned and controlled subsidiaries. The consolidated financial statements of the Operating Partnership include the consolidated financial position and results of operations of the Operating Partnership, 100 First LLC, 303 Second LLC, Redwood LLC, and all of our wholly-owned and controlled subsidiaries. All intercompany balances and transactions have been eliminated in the consolidated financial statements. As of March 31, 2025, the Company owned an approximate 99.0% common general partnership interest in the Operating Partnership. The remaining approximate 1.0% common limited partnership interest in the Operating Partnership as of March 31, 2025 was owned by non-affiliated investors. Both the general and limited common partnership interests in the Operating Partnership are denominated in common units. Generally, the number of common units held by the Company is equivalent to the number of outstanding shares of the Company’s common stock, and the rights of all the common units to quarterly distributions and payments in liquidation mirror those of the Company’s common stockholders. The common limited partners have certain redemption rights as provided in the Operating Partnership’s Seventh Amended and Restated Agreement of Limited Partnership, as amended (the “Partnership Agreement”). With the exception of the Operating Partnership and our consolidated property partnerships, all of our subsidiaries are wholly-owned. The accompanying interim financial statements have been prepared by management in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and in conjunction with the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures required for annual financial statements have been condensed or excluded pursuant to SEC rules and regulations. Accordingly, the interim financial statements do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, the accompanying interim financial statements reflect all adjustments of a normal and recurring nature that are considered necessary for a fair presentation of the results for the interim periods presented. However, the results of operations for the interim periods are not necessarily indicative of the results that may be expected for the year ending December 31, 2025. The interim financial statements for the Company and the Operating Partnership should be read in conjunction with the audited consolidated financial statements and notes thereto included in our annual report on Form 10-K for the year ended December 31, 2024. Commencing January 1, 2025, the Company began presenting a new line item, “Other income (expense)”, which includes tax expenses, acquisition and disposition expenses, and income or expenses related to environmental and sustainability initiatives, which were previously included in general and administrative expenses. Historical amounts for general and administrative expenses and other income (expense) have been revised to conform with the current period presentation. Variable Interest Entities The Operating Partnership is a variable interest entity (“VIE”) that is consolidated by the Company as the primary beneficiary, as the Operating Partnership is a limited partnership in which the common limited partners do not have substantive kick-out or participating rights. At March 31, 2025, the consolidated financial statements of the Company included three VIEs in addition to the Operating Partnership: 100 First LLC, 303 Second LLC, and one entity established during the third quarter of 2024 to facilitate a potential future Section 1031 Exchange. At March 31, 2025, the Company and the Operating Partnership were determined to be the primary beneficiaries of these three VIEs since we had the ability to control the activities that most significantly impact each of the VIEs’ economic performance. As of March 31, 2025, the three VIEs’ total assets, liabilities, and noncontrolling interests included on our consolidated balance sheet were approximately $430.9 million (of which $353.0 million related to real estate held for investment), approximately $20.7 million, and approximately $166.4 million, respectively. Revenues, income, and net assets generated by 100 First LLC and 303 Second LLC may only be used to settle their contractual obligations, which primarily consist of operating expenses, capital expenditures, and required distributions. At December 31, 2024, the consolidated financial statements of the Company included three VIEs in addition to the Operating Partnership: 100 First LLC, 303 Second LLC, and one entity established during the third quarter of 2024 to facilitate a potential future Section 1031 Exchange. At December 31, 2024, the Company and the Operating Partnership were determined to be the primary beneficiaries of these three VIEs since we had the ability to control the activities that most significantly impact each of the VIEs’ economic performance. At December 31, 2024, the impact of consolidating the VIEs increased the Company’s total assets, liabilities, and noncontrolling interests on our consolidated balance sheet by approximately $435.5 million (of which $357.3 million related to real estate held for investment), approximately $18.0 million, and approximately $169.4 million, respectively. Recently Issued Accounting Pronouncements In December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09 “Income Taxes (Topic 740): Improvements to Tax Disclosures.” The ASU is effective for annual periods beginning after December 15, 2024. The Company does not currently anticipate that the guidance will have a material impact on our consolidated financial statements or notes to our consolidated financial statements. 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.” The ASU is effective for annual periods beginning after December 15, 2026. The Company is currently evaluating whether the guidance will have a material impact on our consolidated financial statements or notes to our consolidated financial statements.
