Commercial property insurance
Business insurance that pays to repair or replace a listed building, business personal property and, when included, property of others in the business's care after covered physical loss or damage. Limits, covered causes of loss, valuation, coinsurance, deductibles and exclusions decide what the insurer pays and what the business keeps.
Also called: commercial property, property insurance, business personal property, business personal property coverage, building coverage
After a fire, a break-in or a storm, commercial property insurance is what pays to rebuild the space, replace the furniture and machinery, and restock the inventory. It pays only for the property listed on the declarations, only up to each limit, and only when the cause of loss is covered. The deductible, any excluded cause and any shortfall from too low a limit stay with the business.
How underinsurance shrinks a claim
The standard ISO form, CP 00 10 10 12 (opens in a new tab), pays for direct physical loss of or damage to covered property at the described premises caused by a covered cause of loss. Its coinsurance condition then checks whether the limit is high enough. The form's own example uses property worth $250,000 at the time of loss, an 80% coinsurance requirement, a $40,000 covered loss and a $250 deductible.
Hover or tap a row to highlight it.
| Step | Limit of $100,000 | Limit of $200,000 |
|---|---|---|
| Required insurance ($250,000 × 80%) | $200,000 | $200,000 |
| Share of the requirement carried | $100,000 ÷ $200,000 = 0.50 | Requirement met |
| Loss after coinsurance | $40,000 × 0.50 = $20,000 | $40,000 |
| Insurer pays after $250 deductible | $19,750 | $39,750 |
| Left for the business | $20,250 | $250 |
These figures are the form's illustration, not an average or a quote. Carrying half the required insurance cut the payment roughly in half, even though the loss was well under the limit.
Choices on the policy and what each changes
Each setting moves the premium, the payout or both, according to the California Department of Insurance's Commercial Insurance Guide (opens in a new tab):
- Coverage parts. Building, business personal property and personal property of others can each carry their own limit. A higher limit raises the premium and the most the policy can pay.
- Causes of loss. Basic and broad forms list the perils they cover. Special form covers direct physical loss unless excluded, which is broader and usually costs more.
- Valuation. Actual cash value deducts depreciation. Replacement cost pays to replace with property of like kind and quality, subject to the policy conditions. Agreed value pays a stated amount and can waive the coinsurance penalty when its conditions are met.
- Coinsurance. The ISO form illustrates 80% and 90% requirements. Falling short reduces the claim by formula.
- Deductible. A higher deductible lowers the premium and raises the business's share. On the ISO form it is subtracted from the adjusted loss and applied once per occurrence.
- Business income. This adds coverage for lost income and continuing expenses when covered physical damage shuts the business down, with its own limit, waiting period and restoration period, according to the NAIC's business interruption and BOP overview (opens in a new tab).
- Packaging. A monoline policy carries property alone; a business owner's policy or a commercial package policy combines it with other coverage, which can change eligibility, pricing and exclusions.
Where you see the term
Commercial property appears in business owner's policies, commercial package policies and stand-alone property policies, and homeowners insurance is not a substitute for it. Inventory or equipment kept at home can need separate coverage or an endorsement, according to the NAIC's homeowners insurance guide (opens in a new tab).
On paper, the declarations page lists the covered premises, each limit, the deductible, the valuation method, the coinsurance percentage and the endorsements. You also meet the term on quotes, binders, renewals, lease and lender requirements, claim letters and certificates of property insurance. A certificate of insurance confirms that insurance exists but does not change the policy's coverage, according to the Connecticut State Insurance and Risk Management Board (opens in a new tab). A tenant should read the lease and not rely on the landlord's insurance for its own inventory, equipment or improvements, according to the NAIC's small business insurance overview (opens in a new tab).
What changes in Connecticut and New York
Connecticut has no general statute requiring every business to buy commercial property insurance, though a lease, loan or contract can require it. What state law changes is the policy form and the renewal process. Connecticut sets a standard fire insurance policy form under Conn. Gen. Stat. § 38a-307 (opens in a new tab), and after a commercial policy is cancelled or nonrenewed, the insurer must provide a history report covering policy, premium, pricing and incurred-loss information under Conn. Gen. Stat. § 38a-326 (opens in a new tab).
In New York, Insurance Law § 3426 (opens in a new tab) requires a nonrenewal or conditional-renewal notice 60 to 120 days before expiration, subject to the statute's exceptions. A conditional renewal can mean changed limits, reduced coverage, a higher deductible, a new exclusion or a premium increase above 10%. The first-named insured can request loss information, and the insurer must provide it within 10 days of the written request.
Questions to ask an agent or insurer
- What property falls under Building, Business Personal Property and Personal Property of Others, and what limit applies to each? Customers' property may not fit inside the business personal property limit.
- Is the policy named-peril or special form, and are flood, earthquake, wind, water backup, equipment breakdown and ordinance-or-law coverage excluded or available separately? The covered causes of loss decide whether an event is covered at all.
- Is the property valued at actual cash value, replacement cost or agreed value, and what coinsurance percentage applies? Both change the payment amount.
- What deductible applies to each type of loss, and is it a flat amount or a percentage? Wind, hail, flood and earthquake can carry different deductibles.
- Does the policy include business income coverage, and what waiting and restoration periods apply? Property coverage pays for physical damage, not the income lost during a shutdown.
Frequently asked questions
Specific losses raise a few more questions.
Does commercial property insurance cover liability claims?
No. Property coverage pays for physical loss or damage to the business's own building and property. Claims that the business injured someone or damaged their property fall under general liability insurance, and a business owner's policy commonly combines the two.
Does commercial property insurance cover flood?
Flood is commonly excluded, including on special-form policies, unless coverage is added by endorsement or bought separately. The flood definition, limit and deductible on that coverage control the claim. The Connecticut flood insurance guide covers options for Connecticut property.
Is an "all risk" policy coverage for everything?
No. "All risk" is a misnomer, according to the New York Department of Financial Services (opens in a new tab), because exclusions such as flood, earthquake and wear and tear still apply. Read the exclusions before relying on the label.
Why did the insurer pay less than the damage?
The deductible, a limit, coinsurance, depreciation under actual cash value, an exclusion or a condition requiring repair before full replacement-cost payment can each reduce the check. The declarations and the full policy form control the calculation.
