What a California commercial property policy covers

Building and business personal property

Building coverage pays for the structure itself and permanently installed fixtures. Business personal property (BPP) covers furniture, equipment, inventory and, for tenants, improvements they paid for. Owners usually insure the building; tenants usually insure their BPP. Your lease decides who insures what.

Loss of rents and business income

If a covered loss makes the building unusable, loss of rents coverage replaces the rent you would have collected while it is repaired. For an owner-occupied building or a tenant’s business, business income coverage replaces lost income and helps pay continuing expenses.

Ordinance or law (Coverage A, B and C)

When an older building is damaged, the city may require the repairs to meet current code. A standard policy generally does not pay for that. Ordinance or law coverage fills the gap in three parts:

Coverage A: the value of the undamaged part of the building that must be torn down.
Coverage B: the cost to demolish it and clear the site.
Coverage C: the increased cost to rebuild to current code.

Equipment breakdown

Equipment breakdown covers sudden mechanical or electrical failure of systems such as boilers, HVAC, electrical panels and elevators, which a standard property form typically excludes.

What’s usually excluded: earthquake and flood

Standard commercial property policies in California exclude earthquake and flood. Both need separate coverage, either as a standalone policy or as part of a difference in conditions (DIC) policy.

The California market in 2026

Why buildings get non-renewed

When an insurer non-renews a commercial building, the reasons usually include one or more of these:

Location in a wildfire zone or wildland-urban interface
Age and condition of the roof, electrical, plumbing or HVAC
Vacancy or low occupancy
Loss history
A building value the insurer considers too low or out of date

Our high-fire-risk commercial property checklist for 2026 walks through what to fix before you shop, and our high-risk property insurance guide covers harder-to-place buildings.

Admitted vs. non-admitted (E&S) markets

Admitted insurers are licensed in California and their policies are backed by the California Insurance Guarantee Association. Non-admitted, or excess and surplus lines (E&S), insurers can write buildings that admitted insurers decline, but with different protections and required disclosures. See what to know before you accept a non-admitted (surplus lines) policy.

FAIR Plan + DIC for commercial buildings

When no private insurer will write a building, the California FAIR Plan is the state’s insurer of last resort. Its commercial policy is a basic named-perils policy focused on fire, lightning and smoke, with limited other coverage. It does not include liability, and it leaves gaps that a private policy would normally fill.

Under California Department of Insurance (CDI) Stipulation and Order No. 2026-2, the FAIR Plan’s commercial property option allows limits of up to $20 million per building and $100 million per location. Each building and its limit must be listed on the declarations. This higher-limit option is available through July 2028. The CDI confirmed it was still in effect in its August 3, 2026 alert. Rules can change, so we confirm current limits when we quote.

A difference in conditions (DIC) policy from a private insurer is written alongside the FAIR Plan to add coverage the FAIR Plan leaves out, such as water damage, theft, loss of rents or business income, and sometimes earthquake. You will also need separate general liability coverage; see our guide to general liability insurance for California small businesses. Read more in our California FAIR Plan guide and our article on FAIR Plan and DIC coverage.

Earthquake coverage for commercial buildings

Earthquake coverage for a commercial building is bought as a standalone policy or included in a DIC policy. Deductibles are usually a percentage of the building’s insured value rather than a flat amount, so the dollar figure can be large. Building type matters: older wood-frame soft-story apartment buildings and concrete tilt-up warehouses get extra scrutiny from underwriters, and documented seismic retrofit work can help. In San Francisco, see our article on soft-story retrofits, earthquake insurance and loss of rents.

Lessor’s risk only (LRO)

Lessor’s risk only insurance is for owners who lease an entire building to tenants and do not occupy it. It combines property coverage for the building with liability coverage for the owner’s role as landlord. Because tenants run the day-to-day operations, the lease should require them to carry their own liability and property insurance and to name you as an additional insured. See commercial property insurance and your lease and our San Francisco commercial lease insurance checklist.

How to get better terms at renewal

Start 90 to 120 days before your renewal date. That leaves time to answer underwriter questions and shop more than one market. Prepare:

A current statement of values for each building
An updated timeline for roof, electrical, plumbing and HVAC work
Details of fire sprinklers and alarm systems
A five-year loss run from your current insurer
A defensible-space record with photos and dates, if the building is in a wildfire area

Documented mitigation can also earn credits; see California wildfire mitigation discounts in 2026.

Example scenarios

Example scenario: mixed-use building non-renewed after an inspection

Illustrative example, not a real client. The owner of a mixed-use San Francisco building with ground-floor retail and apartments above receives a non-renewal after an inspection flags the roof and older wiring. The owner completes the work, and the broker re-markets the building with an updated systems timeline, invoices and photos, which gives underwriters current information to quote on.

Example scenario: wildfire-interface building on the FAIR Plan with a DIC policy

Illustrative example, not a real client. An owner of a commercial building in a wildfire-interface area cannot find a private insurer willing to write fire coverage. The building is placed on the California FAIR Plan for fire, and a DIC policy is added for water damage, theft and loss of rents, with separate liability coverage.

Example scenario: no ordinance or law coverage

Illustrative example, not a real client. An older building is partly damaged by fire, and the city requires the repaired section to meet current code. The owner’s policy has no ordinance or law coverage, so the cost of the code upgrades is not covered. At the next renewal, the owner adds Coverage A, B and C.

FAQ: Commercial property insurance in California

What does commercial property insurance cover in California?

It covers the building and the business property inside it against covered losses such as fire, smoke, theft, vandalism and some water damage. Policies can add loss of rents or business income, ordinance or law coverage for code upgrades, and equipment breakdown. Earthquake and flood are usually excluded and need separate coverage.

Does commercial property insurance cover earthquakes in California?

No. Standard commercial property policies in California exclude earthquake damage. You need a separate earthquake policy or a difference in conditions (DIC) policy that includes earthquake. Deductibles are usually a percentage of the building’s insured value, so review the deductible as carefully as the premium.

What can I do if my commercial building was non-renewed?

Read the notice for the stated reason, then gather a statement of values, an updated roof, electrical, plumbing and HVAC timeline, and a five-year loss run. A broker can re-market the building to admitted and surplus lines insurers. If no private insurer will write it, the California FAIR Plan with a DIC policy is a fallback.

Does the California FAIR Plan write commercial buildings?

Yes. The FAIR Plan writes commercial property, mainly for fire and smoke. Under CDI Order 2026-2, limits go up to $20 million per building and $100 million per location, available through July 2028. It does not include liability, so owners usually add a DIC policy and separate liability coverage.

What is ordinance or law coverage and why does it matter for older buildings?

When an older building is damaged, the city can require repairs to meet current code. Standard policies generally do not pay for that. Ordinance or law coverage pays for the undamaged portion that must be demolished (A), demolition and debris removal (B), and the increased cost of building to code (C).

What is lessor’s risk only insurance?

Lessor’s risk only (LRO) insurance is for owners who lease their whole building to tenants and do not occupy it. It covers the building and the owner’s liability as landlord. Because tenants control the space, the lease should require them to carry their own insurance and name the owner as an additional insured.

How far ahead should I start my commercial property renewal?

Start 90 to 120 days before the renewal date. That gives time to update your statement of values and building systems information, collect loss runs, answer underwriter questions and compare several markets. Starting late leaves fewer options, especially for older buildings or buildings in wildfire areas.
