SB 1352 California Senate · 2025-2026 Regular Session

Property taxation: newly constructed: reconstructed property.

Summary
The California Constitution generally limits ad valorem taxes on real property to 1% of the full cash value of that property. For purposes of this limitation, "full cash value" is defined as the assessor's valuation of real property as shown on the 1975–76 tax bill under "full cash value" or, thereafter, the appraised value of that real property when purchased, newly constructed, or a change in ownership has occurred. Existing property tax law defines "newly constructed" and "new construction" to mean any addition to real property since the last lien date and any alteration of land or of any improvement since the last lien date that constitutes a major rehabilitation thereof or that converts the property to a different use. Existing property tax law, in the case of real property that has been damaged or destroyed by misfortune or calamity, excludes from the definition of "newly constructed" and "new construction" any timely reconstruction of the real property, or portion thereof, where the property after reconstruction is substantially equivalent to the property prior to damage or destruction. Existing property tax law authorizes the owner of property substantially damaged or destroyed by a disaster, as declared by the Governor, to apply the base year value of that property to replacement property reconstructed on the same site of the damaged or destroyed property within 5 years after the disaster if the reconstructed property is comparable to the substantially damaged or destroyed property. Existing property tax law requires the assessor to use a specified procedure in determining the appropriate base year value of the reconstructed property. In that regard, existing property tax law applies the adjusted base year value of the property substantially damaged or destroyed to the reconstructed property as its base year value if the full cash value of the reconstructed property does not exceed 120% of the full cash value of the property substantially damaged or destroyed. This bill would revise these provisions to instead authorize the owner of property substantially damaged or destroyed by a disaster, for which the Governor proclaimed a state of emergency, to apply the base year value of that property to replacement property, as described above. The bill would, for the determination of base year values of reconstructed property for the 2026–27 fiscal year to the 2034–35 fiscal year, inclusive, apply the lesser of either the above-described determination based on full cash value, or the adjusted base year value of the property substantially damaged or destroyed if the size of the reconstructed property does not exceed 110% of the size of the property substantially damaged or destroyed, to the reconstructed property as its base year value. The bill would make its provisions operative only until January 1, 2036. This bill would make legislative findings and declarations related to a gift of public funds. The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that, if the Commission on State Mandates determines that the bill contains costs mandated by the state, reimbursement for those costs shall be made pursuant to the statutory provisions noted above. Existing law requires the state to reimburse local agencies annually for certain property tax revenues lost as a result of any exemption or classification of property for purposes of ad valorem property taxation. This bill would provide that, notwithstanding those provisions, no appropriation is made and the state shall not reimburse local agencies for property tax revenues lost by them pursuant to the bill.

What changed between versions

02/20/26 - Introduced 04/13/26 - Amended Senate · 8 edits · Apr 13, 2026
MODERATE
The Senate amendment significantly expands SB 1352 by adding an entirely new Section 70.5 to the Revenue and Taxation Code that establishes a comprehensive framework for transferring base year property tax values from disaster-damaged or destroyed property to reconstructed replacement property. The key new provision allows taxpayers to use the lesser of two calculations (a full cash value test or a size-based test) to determine their reconstructed property's base year value, giving them greater tax relief. The amendment also adds specific extended reconstruction deadlines for properties damaged by named 2018 and 2024-2025 California wildfires.
Scope change
The bill's scope expanded substantially from a narrow definitional amendment to Section 70 (clarifying when reconstruction is 'substantially equivalent' and thus not 'new construction') to a comprehensive property tax relief framework under new Section 70.5 that governs how base year values transfer from disaster-damaged property to reconstructed replacement property, including specific fire-related deadline extensions and a time-limited 'lesser of' calculation method.
SCOPE

Added a new Section 70.5 to the Revenue and Taxation Code that creates a full framework for applying base year values of Governor-declared disaster-damaged property to reconstructed replacement property on the same site within 5 years. This is a major expansion beyond the original bill, which only amended Section 70's definition of 'newly constructed.'

Added a provision stating Section 70.5 applies to real property damaged or destroyed by misfortune or calamity on or after January 1, 2017.

The bill now amends both Section 70 and Section 70.5 of the Revenue and Taxation Code, rather than only Section 70 as in the introduced version.

REQUIREMENT

Added a 'lesser of' rule for fiscal years 2026-27 through 2034-35: the base year value of reconstructed property will be determined by whichever is lower - (1) the adjusted base year value if full cash value does not exceed 120% of the original, or (2) the adjusted base year value if the size does not exceed 110% of the original. This gives taxpayers the more favorable of the two calculations.

TIMELINE

Added a sunset provision: the new 'lesser of' size-based determination is operative only until January 1, 2036.

ELIGIBILITY

Added specific extended reconstruction deadlines (3 additional years) for property damaged by named fires: the 2018 Woolsey Fire and Camp Fire (damage between Nov 1-30, 2018), and the 2025 Palisades, Eaton, Hurst, Lidia, Sunset, and Woodley Fires or the 2024 Mountain and Franklin Fires (damage between Nov 1, 2024 and before Feb 1, 2025).

DEFINITION

Added definitions for 'substantially damaged' (improvements sustain physical damage exceeding 50% of full cash value), 'comparable' (similar in size, utility, and function), and 'disaster' (a major misfortune or calamity proclaimed by the Governor as a state of disaster).

TECHNICAL

Added Senator Allen as a co-sponsor alongside Senator Valladares.
