California Earthquake Insurance: The 3 Numbers to Check Before You Decide

You bought a home in California and you have homeowners insurance. Then an earthquake cracks your walls. Does your insurance pay? In many cases, the answer is no.

I walk a lot of first-time buyers through this, and the line I hear most is, "But I have insurance." In California, homeowners insurance and earthquake insurance are usually two separate things. Here's a plain-English guide to what actually matters when you look at earthquake coverage.

Standard homeowners policies usually exclude earthquakes

A standard homeowners policy typically lists earthquake damage as an exclusion. That means if a quake hits, repairs to the structure, your personal belongings, and even the cost of living somewhere else while the home is unlivable may depend on whether you carry separate earthquake coverage.

The simplest check: open your current policy and look for exclusions that mention "earthquake" or "earth movement." Don't guess, and don't rely on someone telling you it's "probably covered."

The three common parts of an earthquake policy

Earthquake policies are usually split into parts, and you should review each one:

Dwelling: the limit for repairing the house itself.
Personal Property: furniture, electronics, clothing, and other belongings.
Loss of Use: additional living expenses, like a rental or hotel, while you can't live in the home.

Every insurer and every policy combines these differently, with different limits. Don't assume two policies are the same just because the categories have the same names.

The number that matters most: the deductible

Most people ask, "What's the annual premium?" With earthquake insurance, the more important question is about the deductible.

Earthquake deductibles are often not a flat one or two thousand dollars. They're commonly a percentage of your dwelling coverage. So the higher your coverage, the larger the dollar amount of the deductible may be. The real question is: "If something happens, how much do I have to pay out of pocket before insurance kicks in?"

Hypothetical example: if your deductible is a set percentage of a large dwelling limit, then after a major quake you might have to cover a significant repair bill yourself before the policy pays anything. Could you write that check? That's the question to think through honestly.

Your lender not requiring it doesn't mean you have no risk

When you get a mortgage, your lender will typically require homeowners insurance but may not require earthquake coverage. Many buyers take that to mean they don't need it.

Your lender is thinking about its loan risk. You need to think about whether your own savings and net worth could absorb a major earthquake. Those are very different starting points.

How to compare: put three numbers side by side

Here's what I suggest to clients:

Open your current homeowners policy and confirm the earthquake exclusion.
Get an earthquake insurance quote, for example from an insurer that participates in the California Earthquake Authority, or from other carriers.
Compare three numbers side by side: dwelling coverage, deductible, and loss of use.

If your home would be expensive to rebuild and the deductible is also high, ask yourself honestly whether you could cover that deductible. If you couldn't, think about how much practical help the policy would really give you.

It's not "must buy." It's "who carries the risk?"

Earthquake insurance isn't a simple "always buy" or "never buy" decision. The real question is: if a big earthquake happened tomorrow, would you rather carry that risk yourself or transfer it to an insurance company?

Every household's savings, home construction, location, and cash reserves are different, so the answer will be different too. Talk it through with a licensed insurance agent or broker and read the policy terms before you decide.

Put it on your checklist while you're buying

The best time to price earthquake coverage is during escrow, not after you get the keys. When you decide how much to offer and how much to borrow, you should already know the possible premium and the deductible you'd have to cover if something happened. That way the cost is part of your budget from day one, not a surprise later.

It also helps to learn the home's year built and construction type while you're doing your due diligence. Different kinds of homes can carry different earthquake risks, and that can affect both the premium and how you think about the deductible. Ask your inspector about anything structural that looks unusual, and ask your insurance agent how the home's age and construction affect pricing. Write these questions on your inspection checklist so nothing slips through, and keep your quotes with your escrow paperwork so you can compare them when you make the final call.
