1- Hire an Engineer and Contractor:


You should hire an engineer or architect licensed in the state of California to evaluate the strength of the building. The engineer or architect must then develop plans for the building’s seismic strengthening in compliance with this program.

You should check if the Contractor is Licensed by the Contractors State License Board of California: http://cslb.ca.gov.

You should ask the Contractor for references for similar work that he has done and call them to ask about their experience.
