Builders risk insurance protects a building under construction from damage or theft before it's finished and occupied

Unlike homeowners or commercial property insurance, which cover completed buildings, builders risk insurance is temporary coverage that starts when construction begins and ends when the building is ready to use. It covers the structure itself, materials on-site, and equipment — but only during the active construction phase. Once you move in or the building opens for business, this policy ends and standard property insurance takes over.

The policy is typically purchased by the property owner or the general contractor, depending on the contract terms. It's not required by law in most places, but lenders almost always require it before they'll fund a construction loan. The cost varies based on the project size, location, construction type, and how long the work will take — but it's usually a fraction of what the finished building will be worth.

Key Takeaways

  • Builders risk insurance covers the structure, materials, and equipment during active construction, but stops once the building is occupied or ready for use.
  • Most construction lenders require this insurance before releasing loan funds, even though it's not legally mandated.
  • The policy typically covers fire, theft, vandalism, and weather damage, but excludes wear and tear, design flaws, and damage from the contractor's negligence.
  • The property owner or general contractor usually buys the policy, and the cost depends on project size, location, and construction timeline.
  • You'll need to report the policy to your lender and provide proof of coverage before construction can begin.

What the policy actually covers

A standard builders risk policy covers physical damage to the building structure, materials stored on-site, temporary structures like scaffolding, and sometimes equipment brought in by contractors. It typically includes fire, lightning, windstorm, hail, theft, vandalism, and collapse from weight of snow or ice. Some policies also cover damage from heavy equipment or vehicles, though that's less common.

What it does not cover matters just as much. The policy excludes wear and tear, design defects, damage caused by the contractor's own negligence, work that was done incorrectly, and damage that happens after the building is occupied. It also won't cover loss of income, delays in construction, or costs to fix problems that existed before construction started. If a contractor damages a neighbor's property, that's covered under the contractor's liability insurance, not builders risk.

Some policies include coverage for temporary utilities, debris removal, and the cost to demolish and rebuild if the structure is damaged beyond repair. Others require you to buy these as add-ons. The exact coverage depends on the specific policy and the endorsements you purchase.

Who buys it and when

The property owner usually purchases builders risk insurance, but the general contractor may buy it instead — the construction contract specifies who is responsible. Whoever buys it names the other party as an interested party on the policy, so both are notified if there's a claim or if the policy lapses.

You buy the policy before construction begins, and it stays active throughout the project. The start date is typically the day work begins or materials arrive on-site, whichever comes first. The end date is when the building is substantially complete — meaning it's weathertight, utilities are operational, and it's ready for occupancy or business use. Once that date passes, the policy automatically expires, and you need to switch to standard property insurance.

If construction takes longer than expected, you can extend the policy by paying an additional premium. If it finishes early, you can cancel and get a refund for the unused portion, though some policies charge a small cancellation fee.

How much it costs and what affects the price

Builders risk premiums are calculated as a percentage of the total construction cost, typically ranging from 0.5% to 2% of the project value — though this varies widely. A $500,000 house might cost $2,500 to $10,000 to insure for the construction period, while a $5 million commercial building could cost $25,000 to $100,000. The exact rate depends on several factors.

Location matters significantly: areas with higher theft rates, severe weather, or older building codes pay more. Construction type affects the rate too — wood frame buildings cost less to insure than steel or concrete structures. The timeline also influences cost: a project expected to take six months will have a different rate than one planned for two years. Your contractor's safety record and experience level can lower or raise the premium. Some insurers also charge more if the site is in a remote area or if there's limited security.

You can reduce the premium by increasing the deductible (the amount you pay out of pocket if there's a claim), by implementing security measures like fencing or cameras, or by bundling builders risk with other insurance policies. Getting quotes from multiple insurers is worth doing — rates vary significantly between companies for the same project.

The claims process if something goes wrong

If damage occurs during construction, you report it to your insurance company as soon as possible, ideally within 24 to 48 hours. You'll need to document the damage with photos or video, provide a description of what happened, and explain how it affects the construction timeline. The insurer will assign an adjuster who inspects the damage and determines whether it's covered under the policy.

If the claim is approved, the insurer pays either the cost to repair the damage or the replacement cost of the materials, depending on your policy terms. The payment usually goes to the property owner or the contractor, depending on who filed the claim and who the policy names. If there's a dispute about whether the damage is covered, you may need to provide additional documentation or get an independent assessment.

One important detail: if the damage was caused by the contractor's negligence or failure to follow safety procedures, the insurer may deny the claim or pursue the contractor for reimbursement. This is why contractors carry their own liability insurance — to cover situations where they're at fault.

How this differs from contractor liability insurance

Builders risk and contractor liability insurance are often confused because they both relate to construction, but they cover different things. Builders risk covers damage to the building itself and materials on-site. Contractor liability insurance covers injury to workers or the public, and damage the contractor causes to someone else's property — like hitting a neighbor's fence with equipment or injuring a passerby.

A complete construction project typically has both policies in place. The general contractor carries liability insurance (often required by law), and the property owner or contractor carries builders risk. Some contractors include builders risk as part of their overall project insurance, while others expect the owner to purchase it separately. The construction contract should clearly state who is responsible for each type of coverage.

What happens when construction is done

As the project nears completion, you'll need to transition from builders risk to standard property insurance. Most builders risk policies end automatically on a specific date — usually 30 to 90 days after the building is substantially complete. You should contact your insurance agent well before that date to set up a homeowners or commercial property policy that starts when builders risk ends.

There's typically a gap of a few days between when builders risk expires and when the new policy begins, so make sure the dates overlap or connect seamlessly. If there's a gap and damage occurs during that time, neither policy will cover it. Some insurers offer a brief extension or a grace period to prevent this, but you have to ask for it.

Once the new policy is in place, the builders risk policy is canceled and you receive a refund for any unused premium. Keep documentation of the builders risk policy for your records — you may need it for warranty claims or if questions arise about when damage occurred during construction versus after occupancy.

Frequently Asked Questions

Do I have to buy builders risk insurance?

It's not legally required in most places, but your construction lender almost certainly requires it as a condition of the loan. If you're paying cash and have no lender, it's optional — but it's still a good idea because construction damage can be expensive and happens more often than you might expect.

What if the contractor already has builders risk coverage?

Some general contractors include builders risk in their project insurance package. If yours does, make sure you're named as an interested party on the policy so you're notified of any claims or cancellations. You should still review the policy limits to confirm they're adequate for your project value.

Does builders risk cover theft of tools and equipment?

Yes, theft of materials and equipment on-site is typically covered. However, tools that belong to individual workers or subcontractors are usually not covered — those workers are expected to carry their own tool insurance or accept the risk themselves. Check your policy to see what's included.

What if construction takes longer than expected?

You can extend the policy by paying an additional premium for the extra time. Contact your insurance company as soon as you know the project will run over — don't wait until the policy is about to expire. Most insurers can extend coverage for a few weeks or months without requiring a new policy.

Can I cancel builders risk early if the project finishes ahead of schedule?

Yes, you can cancel the policy once the building is substantially complete and ready for occupancy. You'll receive a refund for the unused portion of the premium, though some policies charge a small cancellation fee. Once you cancel, make sure your standard property insurance is already in place.
