What Is the Average Cost for Earthquake Insurance?

Earthquake insurance provides financial protection against damage an earthquake can inflict on a home and its contents. While standard homeowners insurance typically excludes damage from earth movement, a separate earthquake policy covers repair or rebuilding costs after a seismic event. The cost varies widely, influenced by factors unique to each property and its location.

Understanding Earthquake Insurance Coverage

Earthquake insurance covers costs for repairing or rebuilding a dwelling, including attached structures like garages, after an earthquake. This coverage extends to structural damage, such as cracked walls or damaged roofs. Policies also protect personal property, covering items like furniture and appliances.

Additional living expenses (ALE), also known as loss of use coverage, help cover costs such as temporary housing, food, and other necessities if the home becomes uninhabitable during repairs. Some policies also offer coverage for building code upgrades, necessary if an older home needs to meet current building standards during rebuilding, and emergency repairs.

Earthquake policies come with specific exclusions. Fire damage, even if earthquake-caused, is typically covered by standard homeowners insurance and excluded from earthquake insurance. Water damage from external sources like floods or tsunamis, even if triggered by an earthquake, requires a separate flood insurance policy. Other common exclusions include damage to land, vehicles, and pre-existing damage.

Earthquake insurance policies feature percentage-based deductibles, unlike fixed dollar amounts in standard homeowners policies. These commonly range from 2% to 25% of the dwelling’s insured value. For example, a 10% deductible on a $500,000 home means the homeowner is responsible for the first $50,000 in damages. Some policies may apply separate percentage deductibles for the dwelling, personal property, and other structures.

Factors Influencing Premiums

Several variables influence earthquake insurance premiums. Geographic location is a primary factor, particularly proximity to active fault lines and high seismic activity. Homes in high-risk zones generally incur higher premiums due to increased damage likelihood. The type of soil a home is built on also plays a role, with properties on sandy or unstable soil often facing higher costs due to greater susceptibility to damage.

Home characteristics substantially contribute to premium calculations. The age of the home is a key consideration; older structures, especially those built before modern seismic codes, may be more vulnerable and cost more to insure. Construction type also affects rates; wood-frame homes generally have lower premiums than rigid materials like brick or masonry, which are more susceptible to earthquake stresses. The home’s foundation type, number of stories, and overall rebuilding cost also impact the premium.

Seismic retrofitting can reduce premiums. Strengthening a home’s foundation by bolting it to the frame, reinforcing chimneys and walls, or installing shear walls significantly lowers damage risk, which insurers often recognize with discounts.

The chosen deductible directly influences the premium. A higher percentage-based deductible results in a lower annual premium but means greater financial responsibility in a claim. Conversely, a lower deductible leads to higher premiums. Coverage limits for dwelling, personal property, and additional living expenses also impact cost; higher limits mean higher premiums. Different insurance providers have varying pricing models, so premiums for similar coverage can differ between companies.

Estimating Your Earthquake Insurance Cost

Obtaining a personalized earthquake insurance estimate involves gathering property details and seeking quotes from various sources. Homeowners need to provide their address, the home’s build year, construction type, and desired coverage amounts for dwelling, personal property, and additional living expenses. This information allows insurers to assess the property’s risk profile.

After compiling information, contact multiple insurance providers to compare their offerings. Many insurers offer earthquake insurance as a standalone policy or an endorsement to an existing homeowners policy. Comparison websites can also facilitate obtaining multiple quotes, simplifying the process of finding competitive rates.

When reviewing quotes, look beyond just the premium amount. Homeowners should examine the proposed deductible, understanding it is a percentage of the coverage limit. Verify specific coverages for the dwelling, personal property, and additional living expenses.

In some states with significant seismic activity, state-specific earthquake insurance programs exist. For instance, the California Earthquake Authority (CEA) is a publicly managed organization that provides earthquake insurance policies in California. While policies cannot be purchased directly from the CEA, they are offered through participating insurance companies.
