Builders risk insurance — also known as course of construction (COC) insurance — is a specialized form of property insurance that covers a building or structure during the period of construction, renovation, or installation. It protects the physical project itself: the structure under construction, the materials incorporated into it, and the materials stored on-site or in transit, from a wide range of covered perils including fire, wind, vandalism, theft, and collapse.

Builders risk insurance is a temporary policy, effective from the date construction begins until the project is complete and the building is ready for occupancy. It addresses a fundamental gap: during construction, a building is not yet a finished structure that can be insured under a standard property policy, but it represents enormous financial value that must be protected.

Builders Risk vs. Homeowners Insurance: Homeowners insurance insures a completed, occupied dwelling. Builders risk insures a structure being built or substantially renovated. Standard homeowners policies contain an exclusion for buildings under construction. During a major kitchen gut renovation or whole-house renovation, the homeowner’s existing policy may continue to provide limited protection — but only for the portions not affected by construction.

Builders Risk vs. General Liability Insurance: Builders risk covers what happens to the building being constructed — fire, storm, theft, collapse. General liability covers what the construction activity does to other people and other property. Both are required on every construction project. Lenders financing construction projects typically require both policies.

Why Standard Property Policies Exclude Construction: Elevated fire risk from combustible materials and hot work, theft and vandalism at rates far exceeding occupied buildings, collapse risk in partially constructed structures, weather exposure through open wall cavities, rapidly changing insured value as materials are incorporated daily, complex insured interest structure with multiple parties, and faulty workmanship risks all make standard policies unsuitable for construction.

Who Needs Builders Risk Insurance: Property owners and developers, general contractors, construction lenders (who require builders risk as a condition of the construction loan with the lender named as a mortgagee), subcontractors with significant material investments, and architects and engineers.

Owner-Purchased vs. Contractor-Purchased Policies: When a contractor controls a builders risk policy, a potential conflict of interest arises if the insured loss is caused by the contractor’s own negligence. Owners on large projects should carefully consider whether to purchase their own policy.

Residential vs. Commercial Builders Risk: Residential policies are simpler and available from standard carriers for individual homebuilders and renovation contractors. Commercial policies include broader coverage components — soft costs, delay in completion, business income, testing and commissioning — with underwriting focused heavily on the general contractor’s experience and qualifications.

New Construction vs. Renovation Projects: Renovation projects are more complex because the existing building has value already insured under a standard property policy that must coordinate with the builders risk policy without gaps or overlaps.

The Critical Transition: Builders Risk to Permanent Insurance: The permanent policy should be applied for and approved before the anticipated completion date so it can be bound immediately upon completion. Set a calendar reminder 60–90 days before builders risk expiration. A gap between the two policies leaves the newly completed building uninsured.

Key Coordination Points: Builders risk and general liability both required; construction loan requires builders risk with lender as mortgagee; subcontractors should carry their own GL and workers’ comp; soft costs coverage should include construction loan interest.
