Anaheim, CA
Orange County
Anaheim homes built before 1940 often lack foundation bolts that tie the wood framing to the concrete stemwall, making them vulnerable to sliding off the foundation in a Newport-Inglewood Fault earthquake. Foundation bolting retrofits are permitted under California Existing Building Code Appendix Chapter A3 and eligible for up to 3,000 dollars in Brace and Bolt grants.
