California Earthquake Insurance: Do You Need It? (2026 Guide)

California earthquake insurance is a separate policy that covers damage to your home, personal belongings, and living expenses after an earthquake. Standard homeowners insurance does not cover earthquake damage. The California Earthquake Authority (CEA) provides most residential earthquake coverage in the state through participating insurers, with deductibles ranging from 5% to 25% of dwelling coverage.

California holds two-thirds of the nation's earthquake risk. Major quakes like Northridge in 1994 and Ridgecrest in 2019 struck on faults that were unknown at the time. Yet the vast majority of California homeowners do not carry earthquake insurance. [1]

Does Homeowners Insurance Cover Earthquakes in California?

No. Standard homeowners insurance in California explicitly excludes earthquake damage. If an earthquake damages your foundation, cracks your walls, or collapses part of your home, your homeowners policy will not pay for repairs. The one exception is fire: if an earthquake causes a fire, your homeowners policy covers the fire damage, not the earthquake damage itself. [2]

California law requires your insurance company to offer you earthquake coverage every two years. If you decline, you are financially responsible for all earthquake damage. [2]

What Is the California Earthquake Authority (CEA)?

The CEA is a publicly managed, not-for-profit organization established in 1996 after the Northridge earthquake caused an estimated $26.4 billion in insured losses (in 2018 dollars). It is one of the world's largest providers of residential earthquake insurance. [3]

CEA policies are sold through more than 20 participating insurance companies. You cannot buy a CEA policy directly. You must purchase it through the same company that provides your homeowners insurance. Key coverage includes dwelling damage up to your homeowners policy limit, personal property protection from $5,000 to $200,000, and additional living expenses from $1,500 to $100,000. [3]

How Do California Earthquake Insurance Deductibles Work?

CEA earthquake deductibles are percentage-based, not flat dollar amounts. You can choose between 5%, 10%, 15%, 20%, and 25% of your dwelling coverage limit. For a home insured at $500,000, a 15% deductible means you'd pay the first $75,000 of earthquake damage out of pocket. [4]

Higher deductibles significantly reduce premiums but increase your financial exposure. The CEA also offers a "Homeowners Choice" policy that lets you customize coverage. For example, you can opt out of personal property coverage to reduce your premium if structural protection is your priority. [4]

How Much Does Earthquake Insurance Cost in California?

Your premium depends on factors including your home's location, construction type, age, foundation, and the coverage and deductible you choose. CEA rates are based on the latest seismic science, not profit. Use the CEA's free online premium calculator at earthquakeauthority.com for a personalized estimate. [1]

Can You Get a Discount on California Earthquake Insurance?

Yes. Older homes that have been seismically retrofitted (bolted to their foundation with braced cripple walls) may qualify for CEA premium discounts of up to 25%. The CEA also facilitates retrofit grant programs to help homeowners afford these improvements. [6]

Retrofitting is more than an insurance play. The California Existing Building Code notes that proper retrofitting can significantly reduce the chance of a home sliding off its foundation during a quake, one of the most expensive types of earthquake damage. [6]
