What is builder's risk insurance in construction?

Builder's risk insurance is property insurance that covers a building while it is under construction, including materials on site and often in transit or storage, against losses such as fire, wind, theft, and vandalism.

Builder's risk insurance, sometimes called course of construction insurance, covers the structure itself while it is being built. If a fire takes out a framed apartment building or thieves strip copper wire from a half-finished house, builder's risk pays to rebuild or replace the lost work and materials. It is property coverage. It does not cover injuries to people or damage to neighbors; that is general liability insurance.

Who buys builder's risk

The contract decides. On many commercial jobs, the owner buys the policy and names the GC and subs as insureds. On others, the GC buys it and includes the premium in the contract sum or general conditions. On residential jobs, a homeowner's existing policy usually does not cover a major renovation or new build, so the builder or owner buys a separate policy. Whoever buys it, everyone with an interest in the work should be on the policy, including the lender.

What it typically covers and excludes

Builder's risk coverage, typical pattern
Usually coveredOften excluded or limited
Fire and lightningFaulty workmanship or design (the defect itself)
Wind and hailFlood and earthquake unless added
Theft of installed work and materials on siteEmployee theft
VandalismWear, tear, and mechanical breakdown
Materials in transit or off-site storage (if endorsed)Contractor's tools and equipment
Soft costs like extra interest or permits (if endorsed)Losses after the building is occupied

Policies vary a lot. Read the actual form, not a summary, and watch for theft exclusions on unsecured sites, water damage limits, and deductibles that differ by peril.

How a claim works on a real job

Say a GC is building a $2.8 million retail building. Halfway through, a storm tears off newly installed roof deck and soaks the drywall stocked on the second floor. The super documents damage with photos that day, secures the site, and notifies the insurer. The adjuster inspects. The policy pays to replace the deck, the drywall, and the labor to remove damaged work, minus the deductible. If the delay pushes completion and the policy has a soft cost or delay in completion endorsement, some extra costs like loan interest may be covered too.

The fight usually comes over cause. If the roof sheathing was not fastened per the drawings, the insurer may cover the resulting water damage but not the cost of redoing the defective fastening.

Common mistakes

  1. Assuming the owner bought it, or the GC did, without seeing the certificate.
  2. Policy limit set at the original contract value and never raised after big change orders.
  3. Letting the policy lapse before the job is accepted, or keeping it after occupancy when coverage may stop.
  4. Not adding stored materials off site or in transit.
  5. Missing the waiver of subrogation, so the insurer can sue a sub after paying a loss.

Frequently asked questions

Does a homeowner's policy cover new construction?

Usually not for a new build or major renovation. A separate builder's risk or renovation policy is typically needed. Ask the homeowner's insurance agent.

When does builder's risk coverage end?

It depends on the policy. Coverage often ends when the building is occupied, put to its intended use, accepted by the owner, or at the policy's expiration date, whichever comes first.

Does builder's risk cover tools?

Generally no. Contractors' tools and equipment are covered under a separate inland marine or equipment floater policy.

Who pays the deductible on a builder's risk claim?

The contract should say. Many contracts make the party responsible for the loss pay the deductible, or split it.
