Builder's Risk vs. Commercial Property Insurance: What's the Difference?

Builder's risk insurance (also called course of construction insurance) covers buildings and structures while they are under construction or renovation. It protects against physical loss or damage to the structure, materials on site, and sometimes materials in transit — from causes like fire, wind, vandalism, theft, and collapse. Builder's risk is a temporary policy tied to the construction period — it expires when the project is complete, typically when the certificate of occupancy is issued or the owner takes possession.

Commercial property insurance covers buildings and business personal property once they are completed and occupied. It covers physical loss or damage to your owned or leased building, equipment, inventory, and improvements from covered perils (fire, wind, water, theft, etc.). Commercial property is an ongoing policy — it renews annually and covers the building during normal business operations, not during construction.

The transition point is typically when the project reaches substantial completion — usually defined by the certificate of occupancy (CO) issuance or when the building owner takes possession and begins using the structure. At that point, builder's risk typically terminates and commercial property coverage needs to be in place. This transition is a critical coverage gap moment — if commercial property is not in place when builder's risk expires, the building is uninsured even if it's sitting completed but empty. Coordinate the policy transition well before the projected completion date.

Builder's risk is typically purchased by whoever has the greatest financial interest in the project — most commonly the property owner or developer. However, general contractors may purchase it when required by contract, and some lenders require it as a loan condition. The policy should name all parties with an insurable interest: owner, GC, subcontractors, and the lender. Review your construction contract carefully — it should specify who is responsible for procuring builder's risk coverage.

No. Builder's risk covers the structure being built and materials incorporated into it — not the contractor's own tools, equipment, and machinery. Contractor tools, scaffolding, equipment, and temporary structures need separate inland marine / contractors equipment coverage. Theft of contractor tools from a job site at night is the most common scenario where builders assume builder's risk covers their equipment — it does not. Each contractor should carry their own inland marine policy for tools and equipment.
