On November 3, 1998, the voters of California approved Proposition 1. This constitutional amendment allows one of two forms of property tax relief for qualified contaminated property.
Property owners may choose from either of the following relief:
Base Year Value Transfer
Subject to certain conditions and limitations, contaminated property may be sold and its base year value transferred to a replacement property of “equal or lesser value”. Both the original property and the replacement property must be located in Alameda County. The replacement property must be acquired or newly constructed within five (5) years after the sale or transfer of the qualified contaminated property. A timely claim must be filed within three (3) years after the replacement property is acquired or newly constructed.
New Construction Exclusion
If structures located on the qualified contaminated property are substantially damaged or destroyed in the course of the remediation of environmental problems, the repair or replacement of such structures may be excluded from the definition of “new construction” provided that the repaired or replacement structure is similar in size, utility, and function to the original structure. An owner must notify the Assessor prior to, or within 30 days of, the completion of the construction project that he or she intends to claim this exclusion.
