California Extends Tax Credits to Turn Vacant Historic Buildings Into Housing
Sacramento, Friday, 2 October 2026.
Governor Gavin Newsom signed Assembly Bill 1265, extending California’s tax credit through 2031 to lower financial barriers for developers converting old, vacant historic structures into new downtown housing.
Legislative Mechanics and Implementation Timeline
Assembly Bill 1265 formally amends multiple sections of the Revenue and Taxation Code to enact the credit for tax years beginning January 1, 2027, through January 1, 2032 [2]. While Bloomberg Tax reports the law was enacted on September 27, 2026, EIN Presswire states Governor Newsom signed the bill on October 1, 2026 [1][2]. [alert! ‘Conflicting dates provided in sources for enactment vs signing’]. The program is scheduled to commence operations in August 2027, at which point it will hold two application cycles annually [1]. Qualified rehabilitation expenditures for certified historic structures are eligible for a 20% credit, capped at $5 million per taxpayer [1]. To ensure accessibility for smaller developments, 20% of these credits are specifically reserved for projects with under $2.5 million in costs [1].
Political Leadership and Policy Intent
The legislation was authored by Assemblymember Matt Haney (D-San Francisco) and signed by Governor Gavin Newsom (D) [1]. This action is part of a broader legislative push, with Assemblymember Haney noting that all 15 bills sent to the Governor’s desk were signed or enacted [3][4]. The policy intent focuses on addressing housing shortages and downtown revitalization by converting vacant historic structures into housing units [1]. San Francisco Mayor Daniel Lurie partnered with Haney on related housing measures, signaling coordinated local and state efforts to increase housing supply [3]. Haney stated the bill helps bring older buildings back to life rather than letting them sit vacant or tearing them down [1].
Economic Impact and Historical Performance
Historical data suggests significant leverage from state credits, with previous initiatives supporting over $200 million in rehabilitation investment via $40 million in credits [1]. Specific past projects include the Building 8 rehabilitation at the former Naval Air Station Alameda, where $10.4 million was awarded for a $52 million project, representing a credit coverage of 20 percent [1]. Additionally, the Hearst Building conversion received $29.6 million awarded for a nearly $162 million conversion [1]. A 2024 economic impact report by Rutgers University for the National Park Service indicated that for every dollar of federal credit cost, substantial federal tax revenue was generated, though state-specific ratios vary [1]. Annual credit allocations will be determined via the state budget process, with advocacy groups pushing for strong funding in the 2027–28 budget [1].
