Commercial Property Insurance

What commercial property insurance covers

Commercial property insurance protects the physical things your business owns or is responsible for. If a covered event like a fire, burst pipe, windstorm, theft or vandalism damages your property, the policy pays to repair or replace it.

Covered property usually includes:

• The building, if you own it, including permanent fixtures like built-in shelving and lighting.
• Business personal property: equipment, machinery, computers, furniture, tools kept on site, and supplies.
• Inventory and stock waiting to be sold.
• Tenant improvements: upgrades you paid for in a leased space, like new flooring or a remodeled kitchen.
• Property of others in your care, on some policies (for example, a client's items left at your shop).

Example: An electrical fire starts in the back room of a small retail store at night. The fire damages shelving, ruins inventory and destroys the point-of-sale computers. Commercial property insurance pays to replace the damaged items, minus the deductible.

What it doesn't cover

Standard commercial property policies have important exclusions:

• Flood is excluded from most policies. Coverage is available separately.
• Earthquake usually needs its own policy or endorsement.
• Wear and tear, mold, rust and poor maintenance are not covered.
• Vehicles need commercial auto insurance.
• Equipment away from your premises usually needs tools and equipment insurance.
• Lawsuits from injured customers need general liability insurance.

Replacement cost vs actual cash value

How a claim is paid depends on the valuation in your policy:

Many policies also have a coinsurance clause: if you insure your property for less than a set share of its value, the insurer can reduce your claim payment. Insure your property for its full replacement value to avoid this.

Example: A shop owner's equipment and inventory would cost $200,000 to replace, but the owner insures it for only half that amount to save on premiums. The policy has a coinsurance clause requiring coverage close to the full value. After a covered fire, the insurer reduces the claim payment because the property was underinsured, and the owner pays a large share of the loss personally. Exact formulas differ by policy, so ask your agent how coinsurance works on yours.

How to estimate your property values

• Building: use the cost to rebuild, not the market price of the property. Land isn't insured.
• Equipment and furniture: list each major item with today's replacement price.
• Inventory: use your typical stock value, and ask about seasonal increases if your stock peaks at certain times of year.
• Improvements: if you paid to remodel a leased space, include the cost to redo that work.

Keep photos, receipts and an updated equipment list stored off site or in the cloud, so you can prove what you owned after a fire or break-in. Review the values every year. Rising building and equipment costs can leave you underinsured without realizing it.

Who needs commercial property insurance?

You should consider it if your business:

• Owns a building, including landlords who rent space to tenants (see our landlord insurance guide).
• Leases a shop, office or studio and has equipment, furniture or improvements to protect. Your landlord's policy covers the building, not your things.
• Keeps valuable inventory, like a restaurant, bakery, or auto repair shop.
• Is required to carry it by a lease or a lender.

If you work only from home, your homeowners policy may cover little or no business property. Read our home-based business insurance guide.

How much does commercial property insurance cost?

According to Insureon's 2026 data from 100,000 small-business customers, the median cost of commercial property insurance is $108 a month. Your premium depends on:

• The value of your building and contents
• The building's construction, age, fire protection and security
• Your location and its risk of storms, wildfire and crime
• Your deductible and valuation (replacement cost costs more)
• Your industry and claims history

Tip: many small businesses buy property coverage through a business owner's policy (BOP), which bundles commercial property with general liability. Insureon's 2026 median for a BOP is $83 a month, less than the median for property insurance alone, because insurers offer the package at a discount to qualifying small businesses.

Useful add-ons

• Equipment breakdown: covers mechanical or electrical failure of machinery, such as an HVAC unit, commercial oven or compressor, which standard property policies often exclude.
• Spoilage: pays for food or perishable stock that spoils after a power outage or refrigeration breakdown. Important for restaurants and bakeries.
• Ordinance or law: helps pay extra costs to rebuild to current building codes after a covered loss.
• Outdoor signs and glass: some policies limit or exclude these unless added.
• Flood and earthquake: separate coverage, important in at-risk areas.

Business interruption coverage

If a fire forces you to close for two months, the damaged equipment is only part of the loss. Business interruption insurance (business income coverage) replaces lost income and helps pay ongoing expenses like rent and payroll while you rebuild. It is often included in a BOP or added to a commercial property policy. Check how long the coverage lasts and whether a waiting period applies.
