This measure, which amends the State Constitution, allows the Legislature to exclude the value of a newly constructed rainwater capture system from a property’s taxable value. Earlier this year, the Legislature passed a law to carry out this measure should it be approved by voters. Under this law, any systems installed between January 1, 2019 and December 31, 2028 would not raise property tax bills. These property tax savings would apply until the property is sold. If a developer installs a system on a new building, the first buyer of the building may claim the property tax savings for the system.
