Property Tax Rules for Reconstructed Property

This law changes how California assesses property taxes on buildings that are reconstructed after being damaged or destroyed, setting a limit on the size of reconstruction to maintain similar tax values.

What This Bill Does

  • Defines 'substantially equivalent' reconstruction as when a building's size does not exceed 110% of its original size after damage or destruction.
  • Applies this definition for property taxes starting from January 1, 2025, for buildings damaged or destroyed on or after that date.
  • Changes how the base year value is determined for reconstructed properties between fiscal years 2026-27 and 2034-35.

Who It Names or Affects

  • Property owners who need to reconstruct buildings damaged or destroyed by misfortune or calamity.
  • Local tax officials responsible for assessing and collecting property taxes.

Terms To Know

Base year value
The assessed value of a property used as the starting point for calculating future property taxes, typically set when there is a change in ownership or new construction.
Substantially equivalent reconstruction
Rebuilding a damaged or destroyed building so that it closely resembles its original size and condition.

Limits and Unknowns

  • The law does not specify how the state will reimburse local agencies for costs related to implementing these changes.
  • It is unclear if there are any exceptions to the new rules for specific types of property or situations.

Official Summary Text

SB 1352, as amended, Valladares.
Property taxation: newly constructed: reconstructed property.
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.
This bill would define “substantially equivalent” for these purposes to include when the size of the improvement after reconstruction does not exceed 110% of the size of the improvement before damage or destruction. The bill would apply this change to lien dates occurring on or after January 1, 2025, for real property that serves as replacement property for property that was damaged or destroyed by misfortune or calamity on or after January 1, 2025. By imposing additional duties on local tax officials, the bill would impose a state-mandated local program.
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, 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.
