About Earthquake Insurance
Standard homeowners insurance does not cover earthquake damage. Earthquake insurance is a separate policy — or endorsement — and is most critical in high-seismic-risk states like California, Washington, and Oregon. California has the CEA (California Earthquake Authority) which offers standardized policies. Older homes built before modern seismic codes face significantly higher risk and premiums. Earthquake deductibles are typically expressed as a percentage of your home's insured value (10–25%), making it important to have adequate savings for partial losses.
Frequently Asked Questions
Does homeowners insurance cover earthquakes?
No. Standard homeowners policies specifically exclude earthquake damage. You need a separate earthquake insurance policy or endorsement to be covered.
What is the CEA?
The California Earthquake Authority is a publicly managed, privately funded insurer that provides earthquake coverage to California homeowners. It's one of the largest earthquake insurers in the world.
What is a typical earthquake insurance deductible?
Earthquake deductibles are usually 10–25% of the dwelling coverage amount — far higher than standard homeowners deductibles. On a $500,000 home with 15% deductible, you'd pay $75,000 before insurance kicks in.
How does building age affect earthquake risk?
Older homes — especially those built before 1980 — may use construction methods that perform poorly in earthquakes (e.g., unreinforced masonry, soft-story framing). Retrofitting can improve safety and lower premiums.
Is earthquake insurance worth it outside California?
In moderate-risk areas like the Pacific Northwest and the New Madrid Seismic Zone in the Midwest, earthquake insurance can be cost-effective. In very low-risk areas, it's usually not worth the added expense.
