Earthquake Insurance, Explained

Every standard homeowners, condo, and renters policy in California excludes earthquake damage. Separate earthquake coverage — most commonly through the California Earthquake Authority (CEA), a publicly managed, privately funded pool sold through regular insurers — is how you protect the largest asset you own from the state's signature risk. Roughly nine in ten California homeowners don't carry it. Sometimes that's a reasoned choice; often it's just inertia. This guide gives you the actual decision framework.

You buy a CEA policy through the same carrier that writes your homeowners insurance (we arrange it alongside your home policy). Key mechanics:

• Percentage deductibles: you choose 5% to 25% of your dwelling limit (15% is standard). On an $800,000 dwelling limit, a 15% deductible means the first $120,000 of quake damage is yours. The deductible isn't a check you write — it's subtracted from the claim payment.
• Coverage choices: dwelling, contents, and loss-of-use limits are selected separately, so you can tune the premium.
• Retrofit discounts: older homes that have been properly bolted and braced (cripple-wall bracing, foundation bolting) can earn discounts of up to 25%. The state's Earthquake Brace + Bolt program periodically offers grants toward the retrofit itself.

What it costs in Los Angeles

Premiums depend on location, soil, construction type, age, and the deductible you pick. For a Los Angeles-area single-family home, CEA premiums commonly run from several hundred dollars to $3,000+ per year. Renters' earthquake policies (contents + loss of use only) are far cheaper — often under $150/year. The CEA's own premium calculator gives instant estimates; we'll run it with you and quote non-CEA alternatives, which sometimes fit better for high-value homes.

Ask three questions:

• Equity: how much of your net worth is in this house? If losing it would be financially unrecoverable, insure it.
• Structure: pre-1980 wood-frame homes on raised foundations (common on the Westside) benefit enormously from retrofit + coverage; a retrofitted home is both cheaper to insure and likelier to survive.
• Rebuild math: could you absorb the deductible AND alternative housing during a rebuild? If yes for small quakes but no for 'the big one' — that is exactly the scenario insurance exists for.

A mortgage does not require earthquake coverage, which is why so many skip it. But after a major event, federal disaster aid is mostly loans, not grants — insurance is the only mechanism that actually restores your equity.

Three parts of a CEA homeowners policy are easy to miss and change the worth-it arithmetic:

• Building code upgrade: $10,000 is included with every CEA homeowners policy, with higher limits available. After a damaging quake, bringing an older house up to current code is often what makes the rebuild unaffordable — this is the coverage for that gap.
• Loss of use: temporary housing, meals, moving and storage — and it carries no deductible. Your percentage deductible applies to the structure and contents, not to keeping your family housed.
• Emergency repairs: the first $1,500 has no deductible, so the tarp, the board-up and the make-safe work don't wait on a claim settlement.

Dwelling, personal property and loss-of-use limits are chosen separately, which is the main lever for tuning the premium to a number you'll actually keep paying.

CEA deductibles are 5%, 10%, 15%, 20% or 25% of your dwelling limit — but not every home can choose freely. Homes with a dwelling limit above $1,000,000, and pre-1980 dwellings on raised foundations without a verified retrofit, are limited to the 15%, 20% and 25% options.

That restriction is the strongest financial argument for a retrofit on the Westside, where raised-foundation homes from before 1980 are the norm: a documented cripple-wall and foundation-bolting retrofit can unlock the lower deductibles and earn a premium discount of up to 25%. If your house is in that category, get the retrofit documented before you shop the policy — the paperwork is worth money.

Earthquake coverage is not just a single-family-home product:

• Renters insure contents and displacement only, so the sums are small. We wrote a separate guide: renters insurance with earthquake coverage.
• Condo owners need two things a homeowners-style policy doesn't give them: coverage for interior improvements (the parts of the unit the HOA master policy doesn't insure) and loss assessment — your share when the association levies a special assessment for quake damage to the building. Master policies commonly exclude earthquake outright, which is exactly how an uninsured owner ends up with a five-figure assessment.
• Mobile homes have their own earthquake policy form; the risk profile (and the value of proper foundation systems) is different again.

If you're on an HOA board, ask us to read the master policy before renewal rather than after an event.
