Property taxation: application of base year value: disaster relief.
(1) 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 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 law, where real property 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 law, pursuant to the authorization of the California Constitution, authorizes the transfer of the base year value of property that is substantially damaged or destroyed by a disaster, as declared by the Governor, to comparable replacement property within the same county that is acquired or newly constructed within 5 years after the disaster, as provided.
