Earthquake insurance protects commercial property owners against most property damage caused by earthquakes, which is typically excluded from standard commercial property insurance policies.
Earthquake damage can be covered by business insurance, but it’s typically sold as a specialty policy or added as a specialized endorsement to commercial insurance.
Earthquakes can wreak havoc on business property, costing insurers a substantial amount of money in repairs and related losses. Because of this, most standard insurance providers exclude earthquake coverage from their commercial property insurance and business owner’s policies (BOPs).
Earthquake insurance often comes at a higher premium, but it provides crucial coverage for businesses at risk of seismic activity, such as those located in California or the Pacific Northwest.
Commercial earthquake insurance is a type of specialty insurance that covers damage caused by earthquakes. It can be purchased as an endorsement, sometimes called a rider, to a standard property insurance policy, or as a standalone policy through specialty carriers, such as excess and surplus (E&S) lines carriers.
Because surplus lines carriers, also known as non-admitted insurers, are licensed only in their home state, they have greater flexibility in the policies they can sell. This includes coverage for catastrophic risks that standard (admitted) insurers won’t offer, such as:
It’s important to note that non-admitted insurers aren’t backed by the state, meaning the state’s guaranty fund won’t cover claims if the carrier becomes financially insolvent.
Another option worth considering is parametric insurance. When a seismic event reaches a defined magnitude threshold, parametric coverage pays the policyholder a predetermined amount right after the incident. This quick cash can help small business owners stay afloat while they wait for their traditional insurance claims to be processed.

Commercial earthquake insurance provides high-limit business property coverage, which can include:
Earthquake insurance generally covers damage from aftershocks, since they’re considered part of the initial seismic event. However, insurers typically consider all tremors within a certain amount of time, often 72 hours, as a single occurrence under one deductible.
Aftershocks occurring after that timeframe may trigger a new claim and additional deductibles.
While commercial earthquake insurance provides crucial coverage for business property, there are some exclusions. Most earthquake policies won’t cover:

Although earthquake coverage generally costs more than standard policies, it provides vital protection from the catastrophic damage earthquakes can cause.
For example, failing to secure coverage can result in:
Small businesses operating in earthquake-prone areas, such as California, Alaska, and Hawaii, often carry commercial earthquake insurance.
However, 75% of the U.S. could experience substantial seismic activity, making earthquake coverage an important consideration for many small business owners.
If you run your business from home, you can secure earthquake coverage with special endorsements on a homeowner’s policy or a BOP to protect your business assets.
Most homeowner’s insurance policies exclude earthquake damage, including structural damage, foundational cracks, and land movement. Even if you add earthquake coverage to your policy, it likely won’t extend to at-home business property, including inventory and equipment.
The cost of commercial earthquake insurance is affected by many key factors, such as:
Commercial earthquake insurance deductibles are different from standard property deductibles in a few ways, from how much they cost to how often they can change.
Here’s a look at these two types of policy deductibles, side by side:
| Standard commercial property | Commercial earthquake insurance | |
|---|---|---|
Type of deductible | Fixed flat amount | Percentage of total insured value (TIV) |
How it’s calculated | Set at policy start, based on several factors | A percentage of building’s value |
Coverage frequency | Per-occurrence or covered claim | Typically applies to all damage within a limited time period (e.g., 72 hours) |
