## What Is Commercial Property Insurance?

Commercial property may fit your business if you own a building or rely on equipment and stock. Compare replacement-cost terms, deductibles and any coinsurance condition, and check lost-income protection separately. [11](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [12](https://content.naic.org/cipr-topics/business-interruptionbusinessowners-policies-bop "Business Interruption Insurance/Businessowner’s Policies (BOP)") [13](https://www.tdi.texas.gov/pubs/consumer/cb021.html "Commercial property insurance guide")

## Key Differences in Commercial Property Insurance

### Coverage and Valuation

Gallagher’s small-business property page describes repairing or replacing buildings, equipment, and store fixtures after fire, windstorm, or a break-in. MMA says it tailors property placement to an organization’s industry and risks but does not publish specific peril terms. A tenant or owner should compare the scheduled building and contents against the causes of loss shown in the proposed policy. [6](https://www.gallaghersmallbusiness.com/insurance-products/buildings-and-property/ "Buildings and Property") [10](https://www.marshmma.com/us/solutions/property.html "Property Insurance | MMA")

### Placement and Buyer Service

Gallagher’s intake asks about the company, business description, additional coverage interests, employee count, and revenue; it also names appraisal and global placement services in its larger property practice. MMA asks buyers to contact an adviser or specialist, without a published quote checklist. Ask whether the property values will be appraised or modeled for replacement cost. [6](https://www.gallaghersmallbusiness.com/insurance-products/buildings-and-property/ "Buildings and Property") [10](https://www.marshmma.com/us/solutions/property.html "Property Insurance | MMA")

## What to Confirm in Commercial Property Insurance Quotes

- Ask Gallagher whether the quote includes tenant contents, inventory, and the building or only the insured party’s property. [6](https://www.gallaghersmallbusiness.com/insurance-products/buildings-and-property/ "Buildings and Property")
- Ask MMA for the proposed peril list, appraisal basis, and any separate flood or catastrophe terms. [10](https://www.marshmma.com/us/solutions/property.html "Property Insurance | MMA")
- Ask both to identify the insurer, scheduled locations, valuation basis, limits, deductibles, and exclusions. [6](https://www.gallaghersmallbusiness.com/insurance-products/buildings-and-property/ "Buildings and Property") [10](https://www.marshmma.com/us/solutions/property.html "Property Insurance | MMA")
