Builders' risk insurance covers a building while it's being built. It pays to repair or replace the structure, materials and supplies on site when they're damaged by a covered event like fire, wind or theft. Once the project is finished and occupied, the coverage ends and regular property insurance takes over.

It sounds simple, and mostly it is. The tricky parts are who buys it, what it leaves out, and how to confirm it's actually in place. That's what this guide walks through.

What builders' risk insurance covers

Builders' risk protects the physical project, not people. Most policies cover:

  • The structure under construction, including foundations, framing and anything permanently installed.
  • Materials and supplies stored on site, and often materials in transit or stored off site for the project.
  • Temporary structures like scaffolding, fencing and construction forms.
  • Common causes of loss such as fire, lightning, wind, hail, theft and vandalism.

Many policies also offer add-ons. Soft costs cover the extra interest, fees and permits you pay when a loss delays the project. Delay in startup covers lost income when the opening date slips.

What builders' risk usually doesn't cover

This is where most surprises come from. Policies vary, but these are commonly excluded or limited:

  • Faulty workmanship or design. The mistake itself usually isn't covered, though damage it causes elsewhere sometimes is.
  • Wear and tear, mold and gradual deterioration.
  • Flood and earthquake, which often need a separate endorsement or carry a lower limit.
  • Contractor tools and equipment. These usually sit on a separate inland marine policy.
  • Existing buildings on a renovation project. The original structure often needs its own coverage.
  • Injuries and third-party property damage. That's a liability exposure, covered by construction liability insurance, not builders' risk.

Always read the exclusions against your contract. The certificate won't list them.

Builders' risk vs. course of construction insurance

They're the same thing. "Course of construction insurance" is simply another name for builders' risk, and you'll see both in contracts and on policies. If someone asks what property insurance for a construction project is called, the answer is either one.

Builders' risk vs. property insurance

The difference is timing and what's being protected.

  • Builders' risk covers a structure that's still being built. It's written for the length of the project, usually a few months to a few years.
  • Commercial property insurance covers a finished, occupied building. It renews every year and includes risks that only exist once people are using the space.

The handoff matters. Most builders' risk policies end when the building is occupied, put into use or accepted by the owner. If property coverage doesn't start on that same day, there's a gap. It's one of the easiest gaps to miss and one of the most expensive to discover.

Who buys builders' risk: owner or contractor?

Either can, and the construction contract decides. On commercial projects, the owner often buys it because they hold the financial interest in the finished building. On many residential and smaller projects, the general contractor buys it and builds the cost into the bid.

What matters is that everyone with a stake is named. Owners, general contractors, subcontractors and lenders can all have an insurable interest. If your contract says you're covered, check that you're actually listed on the policy.

Why builders' risk insurance can be expensive

Premiums are usually figured as a rate applied to the completed value of the project, so bigger projects cost more. Beyond size, these factors move the price:

  • Construction type. Wood frame burns. Steel and concrete hold up better, so they usually cost less to insure.
  • Location. Hurricane, wildfire, hail and flood exposure all raise rates.
  • Project length. The longer the build, the longer the policy runs.
  • Site security. Fencing, lighting, cameras and guards can lower theft and vandalism risk.
  • Deductibles and add-ons. Lower deductibles, soft costs and delay coverage all add premium.

A good broker can show you which of these you can change before the policy is bound.

How builders' risk coverage is calculated

Most policies are written one of two ways.

  • Completed value form. The limit equals the full value of the finished project from day one. It's the most common approach because it's simple.
  • Reporting form. The limit grows as work progresses, and you report the value at set intervals. It can lower premium early on, but late or missed reports can leave you underinsured.

The limit should cover materials, labor and the cost to rebuild, usually without the value of the land. For a deeper walkthrough, see how to calculate building construction coverage.

Builders' risk and the other construction policies

Builders' risk is one piece of a project's insurance program. It usually sits alongside:

  • General liability for injuries and damage to others. See construction liability insurance.
  • Workers' compensation for injured employees.
  • Commercial auto for vehicles used on the job.
  • Umbrella or excess liability for limits above the primary policies.
  • Pollution liability for environmental exposures. See contractors' pollution insurance.
  • Professional liability for design and engineering errors.

On larger projects, some of these are bundled into a wrap-up program. Here's what to track under an OCIP or CCIP.

How to confirm builders' risk is in place

A standard ACORD 25 certificate shows liability coverage, not builders' risk. Property coverage is usually evidenced on a separate form, often an ACORD 28 for commercial projects. When you review it, check:

  • The project address and description match the job.
  • The limit covers the full completed value.
  • The policy dates run through substantial completion, with no gap before permanent property coverage starts.
  • Your company is named as a loss payee or additional insured where your contract requires it.
  • Deductibles are within what the contract allows.

That's a lot to check on every project, and it changes as policies renew. Lumie reads certificates and endorsements against your requirements and flags anything that doesn't match. Here's how certificates of insurance work if you're new to them.

Builders' risk insurance FAQ

Is builders' risk insurance required?

It isn't required by law, but lenders almost always require it on financed projects, and most construction contracts assign it to the owner or the contractor.

When does builders' risk coverage end?

Usually when the project is complete, occupied, put to its intended use or accepted by the owner, whichever comes first. Some policies also end at a fixed expiration date, so extensions matter if the project runs long.

Does builders' risk cover theft?

Theft of materials and installed property is commonly covered. Theft of contractor tools and equipment usually isn't, because those belong on an inland marine policy.

Does builders' risk cover renovations?

It can cover the new work on a renovation. The existing structure often needs separate coverage, so ask your broker how the policy treats it.
