The Central Coast sits on or near several active fault systems. The San Andreas runs east of us. The Hosgri runs offshore from Cambria south past Diablo Canyon. The Los Osos and Shoreline faults are in our backyard. Earthquake exposure here is not theoretical, and most California homeowners learn how their insurance works the wrong way: after a tremor.
Earthquake is not in your standard homeowners policy
This is the first thing most homeowners get surprised by. A standard homeowners policy explicitly excludes earthquake damage. If a quake shifts your house off its foundation, the standard policy does not pay. You need a separate earthquake policy, and you need to buy it before something happens, not after.
Two paths: the CEA and the private market
In California, earthquake coverage typically runs through one of two routes.
The California Earthquake Authority (CEA)
The CEA is a publicly managed insurer that most California homeowners carriers participate in. If your homeowners policy is with a participating carrier, your CEA earthquake policy can be added through the same agent. The CEA covers:
- The dwelling (the structure of your home)
- Personal property, with limits
- Loss of use (additional living expenses if your home is uninhabitable)
- Building code upgrade costs to bring repairs up to current code
- Emergency repairs
Deductibles are set as a percentage of the dwelling limit: 5%, 10%, 15%, 20%, or 25%. Higher deductibles mean lower premiums. For a home insured at $500,000, a 15% deductible means $75,000 out of pocket before coverage kicks in.
That sounds harsh. The math, though, is that earthquake insurance is built for catastrophic loss, not minor damage. A cracked tile is on you. A foundation shifted off its piers is exactly what the policy is built to handle.
The private market
For situations the CEA cannot fit (very high property values, certain construction types, or properties not eligible), private market earthquake carriers can be an alternative. We start with the CEA when your property qualifies and the product fits. We work with private market carriers when the CEA isn’t an option.
What drives the premium
Earthquake premiums are calculated from a combination of:
- Location and fault proximity. Closer to a known active fault means higher premium. SLO County’s variation is real: a property in central Atascadero is priced very differently from one near the coast.
- Soil type. Sandy or fill soils amplify shaking. Rock or compact soils dampen it.
- Construction type. Wood frame is most resilient. Stucco-on-wood is fine. Brick or unreinforced masonry is the most expensive to insure (and the most vulnerable).
- Year built. Newer homes built to current seismic codes are cheaper to insure.
- Retrofits. If your home has been retrofitted (cripple wall braced, foundation bolted), the CEA offers a meaningful discount. The CEA’s Brace + Bolt program offers a grant to help fund retrofits for older homes that qualify.
Bundling with auto: the math worth knowing
There’s a Farmers multi-policy discount applied to your auto premium when you also carry earthquake coverage. Depending on your auto premium and your earthquake exposure, that discount often offsets most or all of the earthquake premium itself. We see this most for homes that aren’t directly on a fault line, where earthquake premiums are moderate.
When we quote, we’ll show you both numbers: what the earthquake policy costs standalone, and what your net cost looks like with the bundling discount factored in.
When most people start considering it
Earthquake coverage tends to come up in three scenarios:
- Buying a home. The lender or escrow process often surfaces the question.
- A nearby earthquake. A tremor that rattles dishes is enough to make a lot of people pick up the phone.
- A coverage review. When we review your homeowners renewal, we ask whether earthquake makes sense for your specific situation. For some clients the answer is yes. For others, the math doesn’t favor it given their construction, location, or budget.
What to do next
If you don’t have earthquake coverage and you’re not sure whether you should, the easiest step is a brief conversation. We’ll look at your property’s location, construction, year built, and retrofit status, then pull a quote through the CEA and (where applicable) the private market. The same call covers your homeowners review if it has been a while.
