## 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. [7](https://www.insurance.ca.gov/01-consumers/105-type/95-guides/09-comm/commercialguide.cfm "Commercial Insurance Guide") [8](https://content.naic.org/cipr-topics/business-interruptionbusinessowners-policies-bop "Business Interruption Insurance/Businessowner’s Policies (BOP)") [9](https://www.tdi.texas.gov/pubs/consumer/cb021.html "Commercial property insurance guide")

## Key Differences in Commercial Property Insurance

### Services Around the Policy

Heffernan says clients arranging commercial property can access claims services, loss control, HR consulting, and risk management and assessment; it also describes large deductibles and captives. Aon lists property claims advocacy, catastrophe modeling, risk control, and crisis management. Ask each broker which named services are included with your placement and who performs them. [6](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage") [3](https://www.aon.com/en/capabilities/risk-management/property-risk-management "Property Risk Management")

### Policy Terms Available in the Records

Aon describes property coverage for buildings and contents against perils such as fire, natural catastrophe, theft, and vandalism, potentially including business interruption. Heffernan lists commercial property among its basic lines but does not publish specific insuring agreements, limits, or exclusions. Request the insurer forms and schedules before comparing the breadth of protection. [3](https://www.aon.com/en/capabilities/risk-management/property-risk-management "Property Risk Management") [6](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage")

### Placement and Buyer Contact

Heffernan says it places property with insurance carriers and invites buyers to contact its brokers; Aon also describes carrier-based brokerage and consulting. Neither reviewed record identifies the insurer for a particular account. Ask both for the proposed markets, compensation disclosures, and the person responsible for placement and claim advocacy. [6](https://www.heffins.com/business-insurance/ "Heffernan Business Insurance Brokerage") [3](https://www.aon.com/en/capabilities/risk-management/property-risk-management "Property Risk Management")
