Q: What can I expect during the earthquake retrofitting process?

• <div><p>First, you can expect the project to be loud. If you have pets, you might want to take them to a friend's house during the day so they are not disturbed by any of the loud noises.

Once the project is complete, a local building inspector will conduct a final inspection to ensure that the retrofitting is up to code.</p></div>

This includes the initial evaluation and plan, bidding and contract paperwork, permitting and approval process, actual work, and final inspection. Your contractor should give you a more accurate time estimate for your specific project, and they may be able to estimate how long the permitting process will take for your area.</p></div>
