CEA Earthquake Insurance Discount After a Retrofit (10–25%)
The California Earthquake Authority gives a hazard-reduction discount of 10–25 percent on the earthquake premium for a wood-framed single-family home built before 1980 with a raised or other non-slab foundation, provided the home meets retrofit and water-heater requirements. The exact tier depends on foundation type and build year. Documentation is either a CEA DRV form signed by a licensed contractor or engineer, or a valid EBB verification number.

CEA — Hazard Reduction Discount
Eligibility — the AND-list
Per CEA, every home claiming the discount must meet all of these:
- One-to-four unit single-family dwelling
- Built before 1980
- Wood-framed construction
- Raised or other non-slab foundation
- Water heater properly secured to the building frame
Miss one and the discount does not apply. The water-heater strap is the most commonly overlooked item — California Plumbing Code §508.2 already requires it, but verifying it on the DRV form is a separate line.
The DRV form path
The Dwelling Retrofit Verification (DRV) form is CEA's checklist. A California-licensed General Contractor, Civil Engineer, or Structural Engineer in good standing completes it and you submit it via your participating CEA insurer.
Alternative, faster path: if you did the retrofit through CRMP's EBB program, CEA accepts the EBB verification number in lieu of a DRV inspection. That is the cleanest way to qualify.
What 10 years of discount is actually worth
A representative example. A 1956 East Bay home (raised foundation, $400K dwelling) at a planning anchor of $1,800/year CEA premium:
| Variable | Value |
|---|---|
| Foundation | Raised |
| Build year | 1956 (1940–1979 bracket) |
| Discount tier | 20% |
| Annual premium savings (planning anchor) | $360 |
| 10-year savings (no rate change) | $3,600 |
The $1,800/year premium is a planning anchor by dwelling value, not a quote. CEA premiums vary with location, deductible and coverage. Put your real number into the calculator for a personal estimate.
Why this often matters more than the EBB grant in dollar terms
A $3,000 EBB base grant is a one-time event. The CEA discount renews every cycle. Over a 10-year horizon, the discount can match or exceed the EBB grant, especially for homes with higher dwelling values and the 25% pre-1939 tier. The "worth it" page stacks both.
FAQ
How much is the CEA discount?
10–25 percent off the CEA earthquake premium, depending on foundation type and build year. Raised-foundation homes get the largest discount: 25% if built 1939 or earlier, 20% if built 1940–1979. Mobilehomes get a flat 21%.
Do I need a DRV form?
Yes, unless you completed the retrofit through EBB. CEA accepts a valid Brace + Bolt verification number as documentation. Otherwise a California-licensed General Contractor, Civil Engineer, or Structural Engineer signs the DRV form, which gets submitted to your CEA insurer.
Is the discount only on retrofitted homes?
The discount requires the qualifying retrofit features (bolting, cripple wall bracing, water heater strap) be in place. It is not a discount for buying CEA — it is a discount for the home meeting the hazard-reduction criteria.
How long does the discount last?
Renews every cycle for as long as the home stays qualified. Over 10 years on a $1,800/year premium with the 20% tier, that is $3,600 saved — often comparable to the EBB grant.
What about slab-on-grade homes?
Slab-on-grade does not qualify for the hazard-reduction discount under the published CEA tiers (the tiers cover raised and other non-slab foundations). The retrofit scope is also different from EBB.
