California earthquake insurance is sold separately from your homeowners policy, isn’t required by state law or by most mortgage lenders, and is bought by only about 10% of California homeowners even though standard homeowners policies specifically exclude earthquake damage. If you want protection against quake losses, you have to buy a standalone earthquake policy, most often through the California Earthquake Authority (CEA).
Is Earthquake Insurance Required in California?
No. California law does not require homeowners to carry earthquake coverage. It does require insurers to offer it. Under the California Insurance Code, any company that writes a residential property policy in the state has to present you with the option to add earthquake coverage, either by underwriting the risk itself, using an affiliated insurer, or connecting you with a non-affiliated carrier through an agent or broker.1California Legislative Information. California Code Insurance Code 10084 – Earthquake Insurance Most insurers meet that obligation by participating in the CEA, a publicly managed, privately funded entity that is one of the largest residential earthquake insurers in the world and currently holds roughly $19 billion in claim-paying capacity.2California Earthquake Authority. About CEA
Mortgage lenders generally don’t require it either. Fannie Mae and Freddie Mac, which back most U.S. home loans, do not require earthquake coverage even for California homes in high-risk zones.3Federal Housing Finance Agency Office of Inspector General. Disaster Risk for Enterprise Single-Family Mortgages Private portfolio lenders can technically require it, but few do. In practice, buying earthquake coverage is your decision.
What a CEA Homeowners Policy Covers
A CEA homeowners policy includes several coverage types, some standard and some optional:
- Dwelling coverage matches the insured value on your regular homeowners policy. Insure the house at $400,000 there, and the CEA policy insures it at $400,000 too.
- Personal property coverage for belongings like furniture and electronics, at limits of $5,000 or $25,000.
- Loss of use coverage for additional living expenses if the home becomes uninhabitable, with limits from $1,500 to $100,000 and no deductible.
- Building code upgrade coverage of $10,000 included on every policy, with options to raise it to $20,000 or $30,000.
- Emergency repairs up to 5% of your dwelling and personal property limit, with no deductible on the first $1,500.
Deductibles Are the Sticker Shock
Dwelling deductibles come in tiers of 5%, 10%, 15%, 20%, or 25% of the home’s insured value. On a $500,000 home, even the lowest tier means the first $25,000 of damage is yours. Homes valued above $1,000,000, and older homes built before 1980 on a raised foundation without a verified seismic retrofit, are limited to the 15%, 20%, or 25% tiers.4California Earthquake Authority. Coverage Options for Homeowners The homes most likely to sustain serious quake damage are the same ones pushed into the highest deductibles.
Between premiums that run from several hundred to several thousand dollars a year and deductibles that start at 5%, most California homeowners look at the math and self-insure. Whether that’s the right call depends on your equity, your ability to absorb a large loss, and how much your home’s construction type raises or lowers the risk.
Coverage for Renters and Condo Owners
Earthquake coverage isn’t only for people who own a house. The CEA writes renters policies that cover personal property at $5,000 or $25,000 limits with deductibles from 5% to 25%, and loss of use up to $100,000 with no deductible for temporary housing and food costs.5California Earthquake Authority. California Renters Earthquake Insurance Because there’s no structure to insure, renters premiums run substantially lower than homeowners premiums.
Condo owners face a different problem. A homeowners association’s master policy may not cover earthquake damage at all, or may carry a deductible so large the association has to levy a special assessment on every unit owner to pay for repairs. Loss assessment coverage, sold as an add-on to a condo policy, can help pay your share of that assessment. Before deciding whether you need it, read the association’s master policy so you know what the building is actually insured for and what a post-quake assessment could look like.
What Happens If You Don’t Have Earthquake Insurance
Federal disaster aid exists, but it isn’t a replacement for insurance. FEMA’s Individual Assistance program currently caps housing assistance at $43,600 and other needs assistance at $43,600, so the combined maximum won’t come close to rebuilding a destroyed home.6Federal Register. Notice of Maximum Amount of Assistance Under the Individuals and Households Program If you do carry insurance, FEMA subtracts your insurance payments from any award for real property damage; you can’t collect twice for the same loss.7Federal Emergency Management Agency. Duplication of Benefits Fact Sheet
The Small Business Administration offers disaster loans of up to $500,000 for homeowners to repair or replace a primary residence, at interest rates up to 4% if you can’t get credit elsewhere or up to 8% if you can.8U.S. Small Business Administration. Physical Damage Loans These are loans, not grants. A homeowner who loses a $600,000 home and qualifies for the maximum SBA loan is still paying that back for decades, likely on top of the original mortgage. Total federal assistance also can’t exceed the pre-disaster fair market value of the property, so the ceiling on help is real.
Retrofit Discounts and Grants
If cost is the reason you’re not buying coverage, a seismic retrofit can change the numbers. Retrofitting earns a CEA premium discount that depends on when the home was built and its foundation type:
- Built 1940–1979, raised foundation: 20% discount
- Built 1940–1979, other non-slab foundation: 10% discount
- Built 1939 or earlier, raised foundation: 25% discount
- Built 1939 or earlier, other non-slab foundation: 15% discount
To qualify, the home must be a wood-framed single-family dwelling built before 1980, with a raised or non-slab foundation, a properly secured water heater, and a retrofit completed to California standards.9California Earthquake Authority. Earthquake Insurance Policy Premium Discounts A retrofit also unlocks the lower 5% and 10% deductible tiers for pre-1980 homes that would otherwise be capped at 15% or higher.4California Earthquake Authority. Coverage Options for Homeowners
The Earthquake Brace + Bolt program helps pay for the retrofit itself. Eligible homeowners can receive a grant of up to $3,000, and income-eligible households earning $94,480 or less per year can qualify for an additional grant of up to $7,000. The program targets wood-framed homes built before 1980 on raised foundations, the type most likely to slide off the foundation during shaking.10California Residential Mitigation Program. The Earthquake Brace + Bolt Retrofit A typical foundation bolting retrofit runs from roughly $800 to $15,000 depending on the home’s size and condition, so the grants often cover a large share of the cost.
Retrofitting first and then pricing coverage at the discounted rate is the sequence that makes an earthquake policy worth carrying for a lot of California homeowners who would otherwise walk away from the premium.
