Commercial Property Insurance

No. Earthquake is excluded from standard California commercial property policies, so it is purchased separately, either through a private earthquake insurer or in some cases a specialty market. The mechanic that surprises people is the deductible, which is typically set as a percentage of the coverage limit rather than a flat dollar amount, so the out-of-pocket figure scales with the value insured. It is also worth knowing that building, contents, and business income inside an earthquake policy can carry their own limits and deductible treatment rather than moving together.

Flood is also excluded from standard commercial property policies and is written separately. For commercial risks that is usually through a private flood market or, for eligible buildings, the federal program, and the two differ in available limits and in how contents and business income are treated. Flood zone matters less than people expect for whether you can buy it and more for what it costs, and a property outside a mapped high-risk zone can still flood. Coverage normally has a waiting period before it takes effect, so it is not something to arrange when rain is forecast.

Annually, and any time the building or the contents change. Renovations, new equipment, higher inventory levels, and a new location all move the number. Two California pressures move it without you doing anything. Construction costs have risen sharply, which quietly puts a building out of compliance with its coinsurance clause. Code requirements also change, and a rebuild must meet current code rather than the code the building was built to, which is what ordinance or law coverage exists to fund.

Report it, protect the property from further damage, and document before you clear anything. The duty to mitigate is in the policy, and reasonable emergency repairs are usually recoverable, so keep every receipt. Photograph and inventory before disposal, since an adjuster cannot inspect what is already in a dumpster. Keep a log of downtime, because that feeds the business income claim. California’s fair claims settlement regulations give the insurer 40 days after receiving proof of claim to accept or deny it in whole or in part. Current as of August 2026.

By penalizing you at claim time for insuring the building for less than it is worth. A coinsurance clause requires the limit to equal a stated percentage of the property’s value, often 80, 90, or 100 percent. Fall short and the insurer pays only the proportion you did carry, even on a small partial loss. A building worth $1,000,000 insured for $600,000 under an 80 percent clause is carrying 75 percent of what was required, so a $100,000 loss is reduced accordingly. Rising construction costs in California move buildings into breach quietly, without anything changing on the policy.

Evaluate the replacement cost of your building and contents, considering factors like location, industry-specific risks, and the value of your assets. Because the right limits depend on the specific property, operations, and any contract or lease requirements, review your individual needs with a licensed agent or qualified advisor rather than working from a general figure.

The losses it excludes are mostly the slow ones and the ones that belong elsewhere. Wear, deterioration, rust, and settling are maintenance rather than sudden loss. Faulty workmanship, design, or materials are excluded, though resulting damage may still be covered. Employee dishonesty belongs to crime coverage, property in transit to inland marine, and vehicles to commercial auto. If you lease, the building itself is your landlord’s. Earthquake and flood are excluded and written separately. Code-required upgrades on a rebuild are also outside the base form unless ordinance or law coverage was added.
