Under Prop. 13, property in California is reassessed at market value only when it is sold. In between changes of ownership, the assessed value can only go up by an inflation rate of up to 2 percent per year. If the homeowner makes a major improvement, it’s added to the assessed value, but it does not trigger a reassessment of the entire property.
As a result, people who have owned a home for many years pay far less in property tax than they would if they purchased the same house today, or in some cases even a smaller one.
In the past, many Marin homeowners have taken advantage of a state law that gives homeowners who are at least 55 or disabled a once-in-a-lifetime chance to transfer the property tax base from their primary residence to one of equal or lesser value. Prop. 60 lets longtime homeowners 55 or older who have a low property tax assessment avoid a potentially steep tax increase, even on a cheaper home.
The catch is that the replacement home must be in the same county as the current property. Prop. 90 exceptions allow portability of tax base to replacement homes in eleven California counties that accept inter-county transfers of property tax assessments. In the Bay Area, only San Mateo, Santa Clara and Alameda counties participate.
