Standard homeowners and renters policies don't cover earthquakes — the damage is specifically excluded. Whether a separate policy is worth it comes down to where you live and what you'd lose in a major quake. Here's how to decide, with live local risk from USGS.
Nearly every homeowners, renters, and condo policy contains an earth-movement exclusion — earthquakes, landslides, and sinkholes are all carved out. One nuance: if a quake starts a fire, the fire damage is usually covered under your standard policy, but the structural damage from the shaking itself is not.
That gap is the whole reason earthquake insurance exists. It's sold either as a standalone policy or as an endorsement (a rider) added to your existing coverage, and it pays for structural repairs, often the contents of your home, and additional living expenses if your home is uninhabitable after a quake.
1. How active is your area? This is the biggest factor. If damaging quakes are realistic where you live, coverage is worth pricing. Check the recent earthquake history and fault context for your city:
2. What would you lose? The more home equity you have — and the less you could absorb a full rebuild out of savings — the more a policy protects. 3. Could you self-fund? Federal disaster aid after a quake usually arrives as loans, not grants, so "the government will cover it" isn't a plan.
Unlike most insurance, earthquake deductibles are a percentage of your coverage limit — commonly 10–25% — not a flat dollar figure. On a home insured for $400,000, a 15% deductible means you cover the first $60,000 of damage yourself.
That's by design: it keeps premiums affordable and makes the policy catastrophe coverage. Minor quakes rarely exceed the deductible, so earthquake insurance pays off in a major, damaging event — not for hairline cracks. A lower deductible costs more in premium; a higher one costs less.
In California, most residential earthquake policies are written through the California Earthquake Authority (CEA) and sold by your existing home insurer. In other states, coverage comes from private insurers or as an endorsement on your current policy. Note that earthquake and flood are separate risks — flood is covered through the NFIP, not by an earthquake policy, and vice versa.
Because premiums swing widely with your address, the building's age and construction, and the deductible you pick, the only way to know your number is to get quotes for your specific home and compare a couple of deductible levels.
No. Standard homeowners, renters, and condo policies specifically exclude damage from earth movement, including earthquakes. Earthquake coverage has to be bought separately — as a standalone policy or an endorsement added to your existing one.
It depends on three things: how seismically active your area is, how much home equity or personal property you'd lose in a major quake, and whether you could afford to rebuild or replace your belongings out of pocket. If you own in an active region and couldn't self-fund a rebuild, it's worth pricing. If you rent with few valuables, it matters far less.
Premiums vary widely by location, the age and construction of the building, and the deductible you choose. Older homes and higher-risk zones cost more; a newer home on stable ground costs less. Because the deductible is a percentage of your coverage, choosing a higher deductible lowers the premium. Get quotes for your specific address to know your number.
Not by default — the earth-movement exclusion applies to renters policies too. But renters can usually add earthquake coverage for personal belongings, which is often inexpensive relative to a homeowner's policy because there's no structure to insure.
Earthquake deductibles are percentage-based — often 10–25% of your dwelling coverage — so they're high in dollar terms. Minor quakes rarely cause enough damage to exceed the deductible. Earthquake insurance is really catastrophe coverage: it pays off in a major, damaging event, not for hairline cracks.
