Earthquake Mitigation/Seismic Retrofit New Construction Exclusion:
Specified seismic retrofitting and earthquake hazard mitigation features that are added to existing buildings may be excluded from reassessment. An owner must notify the Assessor prior to, or within 30 days of, the completion of the construction project that he or she intends to claim this exclusion. The applicant must also certify (or have certified) to the Assessor in writing those portions of any new construction project that are specifically attributable to seismic retrofit or earthquake mitigation technologies.
Previously installed seismic retrofit or earthquake mitigation technologies are NOT excluded from reassessment when property changes ownership. (R&T 74.5)
