Earthquake Insurance: Is It Separate and Do You Need It in California?

By the PolicyZen Team · Updated March 2026 · 8 min read

More than 10 million California homeowners don't have earthquake insurance. If a major earthquake damages their home, they're entirely on their own. Standard homeowners insurance explicitly excludes earthquake damage — it's not an oversight, it's a deliberate exclusion that has been standard practice for over a century.

Earthquake insurance is a completely separate policy from homeowners insurance. It covers structural damage to your home, loss of personal property, and additional living expenses while your home is uninhabitable after an earthquake. In California, most earthquake insurance is purchased through the California Earthquake Authority (CEA) — a publicly managed, privately funded program that covers about 85% of California's residential earthquake insurance market.

What Earthquake Insurance Covers

The Deductible — The Biggest Surprise

Earthquake insurance deductibles are not a flat dollar amount — they're a percentage of the dwelling coverage limit. On a home insured for $800,000 with a 15% deductible, your earthquake deductible is $120,000. You pay the first $120,000 of damage before insurance pays anything.

CEA deductible options: 5%, 10%, 15%, 20%, 25%. Lower deductible = higher premium. Many homeowners choose 15-25% deductibles to keep premiums manageable, but need to understand they'd pay six figures before coverage kicks in after a major event.

Cost in California

Annual premiums vary significantly based on location, soil type, home construction, age, and coverage amounts. Rough ranges:

Only about 13% of California homeowners have earthquake insurance. After a major earthquake, federal disaster assistance averages less than $10,000 per household — far less than the cost of major structural repairs. The state cannot bail out millions of uninsured homeowners simultaneously. The financial recovery risk from a major uninsured earthquake loss is a legitimate catastrophic exposure.

Should You Buy It?

Consider earthquake insurance if: you're near an active fault, your home is on soft soil or fill (check USGS liquefaction maps), your home is older construction, you couldn't afford to repair or rebuild without insurance, or you have significant equity to protect.

Does earthquake insurance cover fire after an earthquake?
Post-earthquake fires (from broken gas lines, electrical damage) are typically covered by your standard homeowners policy, not your earthquake policy — because fire is a covered peril in homeowners insurance regardless of the cause. This means homeowners without earthquake insurance might have some coverage for fire damage if the fire was earthquake-triggered, but not for the direct structural shaking damage.
