Your business earthquake policy will generally cover damage to your building and to your business property such as your inventory. Depending on the policy, lost business income caused by an earthquake may also be covered. Coverage only begins when damage has exceeded your policy’s deductible—the amount you pay out of pocket before your insurance kicks in. Earthquake insurance policies often have high deductibles—ranging from 2 percent to as high as 20 percent of the value of your building, depending on its location, age and condition.
