Foundation & seismic
How much does foundation repair cost in California?
California foundation repair costs $4,500–$45,000+ in 2026. Cripple-wall bracing and bolt-down retrofit runs $4,500–$9,500, partial pier replacement $12K–$25K, and full lift-and-replace on a single-story home $35K–$80K depending on access.
Seismic retrofit is the most common foundation work in California, especially in pre-1980 homes. Bay Area and LA-Basin homes near fault traces are top priority — see the Bay Area foundation guide for fault-proximity context.
Always start with a foundation inspection by a licensed structural engineer; cost is $400–$1,200 and produces the scope letter contractors bid against.
