Does an Earthquake Retrofit Lower Your Insurance in California?
Yes, for qualifying homes. The California Earthquake Authority (CEA), which writes most residential earthquake policies in the state, offers a premium discount of up to 25% on older raised-foundation houses that have been retrofitted to its standard and verified. The retrofit has to include foundation bolting and, where there's a cripple wall, plywood bracing. Here's who qualifies, how the discount is verified, and what it's worth against the cost of the work.

Which houses qualify for the CEA retrofit discount?
The CEA discount is aimed at the houses most likely to be damaged: older wood-frame homes on raised foundations. In general terms, a home qualifies when:
- It was built before 1980.
- It sits on a raised foundation with a crawlspace, not a slab.
- The sill plate is bolted to the foundation.
- Any cripple wall is braced with structural plywood.
- The water heater is strapped.
How much is the discount worth?
Up to 25% off the earthquake policy premium, depending on the home and the retrofit standard met. On a policy running $1,200 a year, that's about $300 a year, every year. Against a $5,000 to $10,000 retrofit, the discount alone pays back the job in 15 to 30 years. The discount isn't the reason to retrofit; keeping the house on its foundation is. But it's real money that keeps coming.
Check your current premium and ask your insurer for the exact percentage for your house. Rates and discount tiers change, and the CEA publishes current figures on its site.
How does the insurer verify the retrofit?
The CEA uses a Dwelling Retrofit Verification Form that your insurance agent submits. It asks for the construction details of the retrofit: bolt type and spacing, cripple wall height, plywood grade and nailing. Some insurers accept a contractor's documentation and photos; some want an inspection.
That's why we photograph every anchor and every panel and give you a written record. Hand the packet to your agent, and the form fills itself in.
What if the house doesn't have earthquake insurance?
Most California homeowners don't carry it; standard homeowners policies exclude earthquake damage. The retrofit still matters more than the discount. A house that slides off its foundation in a major quake routinely costs ten times the retrofit to put back, and without earthquake coverage that cost is yours. We'll say that once and leave it there.

Common Questions
Do I need to use a CEA-approved contractor to get the discount?
The CEA discount is about the work meeting the standard and being verified, not about a contractor list. Ask your insurer exactly what documentation they want before the job so we can produce it.
Does the discount apply to a slab house?
No. The retrofit discount is for raised-foundation homes. A slab-on-grade house has no sill to bolt or cripple wall to brace, so there's nothing to verify. A water-heater strap is still worth doing.
Can I get the discount if the house was retrofitted years ago by a previous owner?
Yes, if it can be verified. If you don't have the paperwork, we can inspect the crawlspace, photograph the existing bolts and plywood, and write up what's there so your agent can submit it.
Is the retrofit discount the same as the Earthquake Brace + Bolt grant?
No. The grant is a separate state program that helps pay for the retrofit itself, with its own eligibility and ZIP-code rules. The insurance discount applies after the retrofit exists, whoever paid for it. Check the CEA and Brace + Bolt sites for current details on the grant.
