Informal Request for Decline In Value (Prop 8)

  • A Proposition 8 reduction is a form of assessment relief. It may be applied by the Assessor when a property's assessed value exceeds the current market value. By the end of June, all Santa Clara County property owners receive notification of their assessed value. At that time an informal Proposition 8 request for a reduction below the assessed value could be submitted to the Assessor. Requests for review must have been submitted to the Assessor’s Office by August 1, 2025 for the Assessor to consider a change to the 2025/26 roll.
