In California, the base property tax rate is 1% of a property’s assessed value, plus any voter-approved local taxes or special assessments. In San Francisco and Marin, the effective rate typically ranges from 1.1% to 1.25%.
How Property Tax Works in California
California’s property tax system is governed by Proposition 13, which sets the maximum base rate at 1% of assessed value. The “assessed value” is usually the purchase price of the property, with annual increases capped at 2% unless ownership changes.
On top of that base 1%, local jurisdictions can add voter-approved taxes or bond measures. These often fund schools, parks, or infrastructure. That’s why the rate varies slightly depending on where in San Francisco or Marin you own property.
Typical Rates in San Francisco & Marin
-
San Francisco: Around 1.18%
-
Marin County: Around 1.1%–1.25%, depending on the city and local assessments
For example, a $1,500,000 home in San Rafael with a 1.2% effective tax rate would generate an annual property tax bill of about $18,000.
