Earthquake insurance covers damage from ground shaking that your standard homeowners policy will not
Standard homeowners insurance does not cover earthquake damage — not the foundation cracks, not the collapsed chimney, not the broken gas line. If an earthquake damages your house, you pay for repairs yourself unless you have bought a separate earthquake policy. The trade-off is straightforward: you pay an extra premium to shift that risk to an insurance company, but only if the risk matters where you live and you can afford the deductible.
Whether earthquake insurance makes sense depends on three things: how likely earthquakes are in your area, how much damage would cost you, and whether you can absorb that cost if it happens. A homeowner in California faces a very different calculation than one in Ohio. This guide walks through the real advantages and disadvantages so you can decide whether the premium is worth it.
Key Takeaways
- Earthquake insurance is a separate policy you buy in addition to homeowners insurance, and it covers structural damage and some contents that standard policies exclude.
- The deductible is usually 10 to 20 percent of your home's insured value, meaning you pay thousands out of pocket before insurance kicks in.
- Premiums vary wildly by location and building type — a wood-frame house in a low-risk zone might pay $100 to $200 per year, while a masonry home in a high-risk zone could pay $1,000 or more.
- If you live in a low-seismic area or have significant savings to cover repairs, earthquake insurance may not be worth the cost.
- If you live near a fault line, have a mortgage, or cannot afford major repairs, earthquake insurance protects you from financial ruin.
How earthquake insurance actually works
Earthquake insurance is sold as a separate endorsement or policy, not as part of your standard homeowners coverage. You contact your insurance company or agent and request it — it does not come automatically. The policy covers structural damage to your home (walls, foundation, roof), built-in appliances, and sometimes personal property inside, depending on what you choose.
The deductible is the catch. Most earthquake policies use a percentage deductible rather than a flat dollar amount. That means if your home is insured for $400,000 and your deductible is 15 percent, you pay the first $60,000 of any earthquake damage yourself. The insurance company pays the rest, up to your policy limit. This is very different from a $1,000 deductible on your homeowners policy — you are responsible for a much larger share of the loss.
Coverage limits work the same way as homeowners insurance: you choose how much your home and contents are insured for, and that is the maximum the company will pay. If your home is insured for $400,000 and damage totals $500,000, you get $400,000 and pay $100,000 yourself (after meeting the deductible).
The cost varies dramatically by location and building type
Earthquake insurance premiums depend almost entirely on where you live and what your house is made of. A wood-frame house in a rural area far from any fault line might cost $100 to $300 per year. The same house in the San Francisco Bay Area could cost $1,500 to $3,000 per year. A masonry or unreinforced concrete home in a high-risk zone can cost even more.
Insurance companies use detailed seismic hazard maps that show the probability of ground shaking at your specific address. They also factor in your home's age, construction type, and whether it sits on soft soil (which amplifies shaking). A newer wood-frame house on firm ground pays less than an older masonry house on clay soil, even in the same neighborhood.
Some states, including California, have a state-run earthquake insurance program (the California Earthquake Authority) that offers policies when private insurers will not. These programs often have lower premiums than private policies but also lower coverage limits and higher deductibles. If you live in a high-risk area and cannot find private coverage, the state program may be your only option.
The main advantage: protection from catastrophic loss
The strongest reason to buy earthquake insurance is that a major earthquake can cost more than most people have saved. A moderate earthquake can cause $50,000 to $100,000 in damage. A large one can total a house. Without insurance, you would have to pay for repairs out of pocket, take out a loan, or live in a damaged home indefinitely. With insurance, the company covers most of the cost (after your deductible).
This matters most if you have a mortgage. Your lender does not require earthquake insurance the way it requires homeowners insurance, but if an earthquake damages your home and you cannot repair it, you still owe the full mortgage balance. You would be paying a loan on a house you cannot live in and cannot sell. Earthquake insurance prevents that scenario.
Earthquake insurance also covers damage that homeowners insurance will not touch. If an earthquake cracks your foundation, breaks your chimney, or ruptures your gas line, homeowners insurance denies the claim. Earthquake insurance covers it. This distinction matters because foundation and structural damage is often the most expensive part of earthquake repairs.
The main disadvantage: high deductibles and uncertain payoff
The percentage deductible is the biggest drawback. On a $400,000 home with a 15 percent deductible, you pay $60,000 before insurance pays anything. That is more than many people have in savings. Even a 10 percent deductible is $40,000. If you cannot afford to pay that amount out of pocket, the insurance does not help you much — you would still struggle to repair your home.
The second disadvantage is that you may never use it. If you live in an area where major earthquakes are rare, you could pay premiums for decades and never file a claim. That money goes to the insurance company, not to you. Over 20 years, a $200 annual premium adds up to $4,000. If no earthquake happens, that is $4,000 you did not get back.
Earthquake insurance also does not cover everything. It typically excludes landscaping, fences, pools, and detached structures like garages or sheds. It does not cover loss of use (temporary housing if your home is uninhabitable), though some policies offer this as an add-on. Read the policy carefully to understand what is and is not covered.
Who should buy earthquake insurance
Buy earthquake insurance if you live in a seismic zone — California, Oregon, Washington, Utah, or parts of the Midwest and Southeast near fault lines. Buy it if you have a mortgage and cannot afford major repairs out of pocket. Buy it if your home is older, made of masonry or unreinforced concrete, or sits on soft soil, because these homes suffer more damage in earthquakes.
Buy it if you have significant equity in your home and want to protect that investment. Buy it if you live in a multi-story building or in a home that would be expensive to repair. The premium is worth it if the alternative — paying tens of thousands out of pocket — would cause real financial hardship.
You should also consider your local building codes. Homes built before modern seismic codes (roughly pre-1980 in California, later in other states) are more vulnerable. If your home predates these codes and you live in an active seismic zone, earthquake insurance is more valuable because the risk is higher.
Who can probably skip it
Skip earthquake insurance if you live far from any fault line and seismic activity is rare. If you live in the Midwest or East Coast outside of known seismic zones, the risk is low enough that the premium may not be worth it. Check the USGS seismic hazard map for your area — if it shows very low probability of strong shaking, earthquake insurance is less critical.
Skip it if you have substantial savings (at least $50,000 to $100,000) and could absorb the cost of major repairs without borrowing. If you can afford to pay the deductible and some repairs out of pocket, you are self-insuring to some degree, and the premium may not add value.
Skip it if your home is new, well-built, and sits on firm ground. Newer homes built to current seismic codes suffer less damage. If your home is wood-frame (which performs better in earthquakes than masonry), the risk is lower. If you live on bedrock rather than soft soil, ground shaking will be less severe. These factors lower both the risk and the value of insurance.
How to decide: a straightforward framework
Start by finding out your seismic risk. Go to the USGS Earthquake Hazards Program website and enter your address. It will show you the probability of strong shaking in your area over the next 50 years. If the probability is very low (less than 5 percent), earthquake insurance is probably not worth the cost. If it is moderate to high (10 percent or more), it is worth considering.
Next, get a quote. Call your homeowners insurance company or an independent agent and ask for an earthquake insurance quote. Find out the annual premium, the deductible percentage, and what is covered. Calculate what you would actually pay out of pocket in a moderate earthquake (the deductible) and whether you could afford it.
Then ask yourself: if an earthquake caused $50,000 in damage, could I pay my deductible plus any uncovered costs? If yes, you might skip it. If no, buy it. Also ask: how long do I plan to stay in this home? If you are selling in two years, the premium may not be worth it. If you plan to stay 20 years, it is more likely to pay off.
Frequently Asked Questions
Does earthquake insurance cover my personal belongings?
Most earthquake policies cover personal property inside your home, but only if you add it to the policy and only up to a limit you choose. Jewelry, electronics, and furniture are usually covered. Some policies exclude certain items like art or collectibles. Check your specific policy to see what is included and what limits explore.
Can I get earthquake insurance if I have already had earthquake damage?
Most insurance companies will not sell you earthquake insurance if your home has already been damaged by an earthquake. Some state programs may cover you, but with exclusions or higher premiums. If you live in a seismic zone, buy earthquake insurance before damage occurs.
What is the difference between earthquake insurance and a homeowners policy?
Homeowners insurance covers fire, theft, wind, and some water damage, but explicitly excludes earthquakes. Earthquake insurance covers only earthquake damage. You need both policies for full protection. Earthquake insurance is sold separately and costs extra.
Will my mortgage lender require me to buy earthquake insurance?
No. Mortgage lenders require homeowners insurance but not earthquake insurance, even in seismic zones. However, if an earthquake damages your home and you cannot repair it, you still owe the full mortgage balance. Earthquake insurance protects you from this scenario, even though it is not required.
How much does earthquake insurance cost?
Premiums vary widely by location and home type. In low-risk areas, expect $100 to $300 per year. In moderate-risk areas, $300 to $800 per year. In high-risk areas like the San Francisco Bay Area, $1,500 to $3,000 or more per year. Get a quote from your insurance company for your specific address and home.
