A resolution to propose to the people of the State of California an amendment to the Constitution of the State, by amending subdivision (c) of Section 2 of Article XIII A thereof, relating to taxation.

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. This measure would authorize the Legislature to exclude from classification as "newly constructed" the construction or addition, completed on or after January 1, 2019, of a rain water capture system.
