cost for seismic retrofit
Larger homes, homes with many floor levels, steep hillside homes, and homes with finished basement area rooms, or homes with rooms over garages will cost more to retrofit. In these situations, a complete earthquake retrofit can cost $10,000 or more.t this time there is no formal accrediting agency or certification process for seismic retrofitting, even for engineers. Experience, formal and informal training of employees, and a companyâs track record of retrofitted homes are the foundation for its expertise.
