A change in ownership is a transfer that can reset the assessed value, often to current market. It is a tax event, not a walkthrough of how to record a deed.
A change in ownership for property tax is California's reset trigger: a transfer that can restart the assessed value, often at current market. Other states may reassess on sale under a different name. The event is about the tax roll. This page is not a walkthrough of how to record a deed.
What counts as a change in ownership for property tax?
California's Board of Equalization describes a change in ownership as a transfer of a present interest in the property, including beneficial use, that is substantially equal in value to a fee interest, and gives a purchase or an inheritance as examples. Other states use different stamps for a transfer that rewrites the roll. Some exclusions exist. This page does not catalog them.
Example: a house on the roll at $200,000 sells for $400,000. The new print can start at $400,000. Ten mills on $400,000 is $4,000. That jump is an example of a reset, not a closing statement.
Look up if you are overpaying.
Does a change in ownership always raise the property tax bill?
A reset to current market often raises the print when prices have risen since the last start. A property tax appeal, when one is filed, is still aimed at that new printed figure. The property tax glossary and the base-year value page keep the reset next to the starting point. FairAppeal handles the entire appeal on your behalf when a filing goes forward, and there are no upfront costs with Fair Appeal.
