Value Change Notices and Prop 8 Notices

There will not be a notice generated for every property. If your property changed owners or had new construction in 2016, or if the assessed value was adjusted due to a Prop 8 review, then your search should return a notice.

As a cost savings measure, the Assessed Value Change Notices and Prop 8 Notices will no longer be mailed through the U.S. Postal Services unless specifically requested.
