How Prop 60/90 Works
Propositions 60/90 amended section 2 of Article XIIIA of the California Constitution to allow a person who is over age 55 to sell his or her principal place of residence and transfer its base year value to a replacement dwelling of equal or lesser value that is purchased or newly constructed within two years of the sale. These propositions are implemented by Revenue and Taxation Code section 69.5.
Proposition 60 allows for the transfers of a base year value within the same county (intracounty). Proposition 90 allows for the transfers of a base year value from one county to another county in California (intercounty) if the county has authorized such a transfer by an ordinance.
As of November 7, 2018, the following ten counties in California have an ordinance enabling the intercounty base year value transfer:
Alameda
Los Angeles
Orange
Riverside
San Bernardino
San Diego
San Mateo
Santa Clara
Tuolumne
Ventura
Since the counties indicated above are subject to change, we recommend contacting the county assessor's office to which you wish to move to verify eligibility
