Organization, Consolidation and Presentation of Financial Statements [Abstract]
Background and Basis of Presentation	Background and Basis of Presentation Description of Business: Alexander & Baldwin, Inc. ("A&B" or the "Company") is a fully integrated real estate investment trust ("REIT") headquartered in Honolulu, Hawai‘i, whose history in Hawai‘i dates back to 1870. Over time, the Company has evolved from a 571-acre sugar plantation on Maui to become one of Hawai‘i's premier commercial real estate companies and the owner of the largest grocery-anchored, neighborhood shopping center portfolio in the state. The Company operates in two segments: Commercial Real Estate ("CRE") and Land Operations. As of June 30, 2025, the Company's commercial real estate portfolio resides entirely in Hawai‘i and consists of 21 retail centers, 14 industrial assets and four office properties, representing a total of four million square feet of gross leasable area ("GLA"), as well as 146 acres of commercial land, of which substantially all is leased pursuant to urban ground leases. Throughout this quarterly report on Form 10-Q, references to "we," "our," "us" and "our Company" refer to Alexander & Baldwin, Inc., together with its consolidated subsidiaries. Basis of Presentation: The interim condensed consolidated financial statements are unaudited. Because of the nature of the Company's operations, the results for interim periods are not necessarily indicative of results to be expected for the year. While these condensed consolidated financial statements reflect all normal recurring adjustments that are, in the opinion of management, necessary for fair presentation of the results of the interim period, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America ("GAAP") for complete financial statements. Therefore, the interim condensed consolidated financial statements should be read in conjunction with the consolidated balance sheets as of December 31, 2024 and 2023, and the related consolidated statements of operations, comprehensive income (loss), cash flows, and equity and redeemable noncontrolling interest for each of the three years ended December 31, 2024, 2023, and 2022, respectively, and the notes thereto included in the Company's Annual Report filed on Form 10-K for the year ended December 31, 2024 ("2024 Form 10-K"), and other subsequent filings with the U.S. Securities and Exchange Commission ("SEC"). Use of Estimates: The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported. Estimates and assumptions are used for, but not limited to: (i) asset impairments, including intangible assets and goodwill, (ii) purchase price allocations with respect to commercial real estate asset acquisitions, (iii) the determination of fair value of sales-type leases, (iv) litigation and contingencies, (v) postretirement benefits, (vi) recoverable amounts of accounts and other receivables, (vii) valuation of derivatives and their effectiveness as hedges, (viii) income taxes, and (ix) valuation of market-based and performance-based restricted stock units. Future results could be materially affected if actual results differ from these estimates and assumptions. Rounding: Amounts in the condensed consolidated financial statements and notes are rounded to the nearest thousand. Accordingly, a recalculation of some per-share amounts and percentages, if based on the reported data, may result in differences.
