Seismic Safety Construction Exclusion

You may be eligible for a reassessment exclusion if you make seismic safety improvements or use earthquake hazard mitigation technologies on an existing building.
(See Revenue & Taxation Code Section 74.5.) 

• Only the part of your project that includes certified seismic retrofitting is excluded from reassessment.
• This does not include other work like electrical, plumbing, or finishing materials.

Example:
If you spend $100,000 to remodel your property, and $25,000 of that amount is certified as seismic retrofitting, then only the $25,000 is excluded from reassessment.

To qualify, the property owner must:

• File the Claim for Seismic Safety Construction Exclusion from Assessment form
• Include all required supporting documents
• Submit the form within 6 months after the project is finished
