What Is Builders Risk Insurance?

Builders risk protects the project you are building, including materials meant for it, against physical loss until construction ends. The gaps that cost owners money are materials in storage or transit, the existing building in a renovation, and coverage ending when you occupy early.

What Does Builders Risk Insurance Cover?

In a renovation, one sample builders risk form excludes the existing structure, so a policy on the new work alone can leave the older building unprotected. 2,4 The same form separates materials built into the project from the contractor's tools. 4

New Work and Existing Buildings

When you renovate, identify the new work and existing structure separately in the quote discussion. 2,4

Materials and Contractor Tools

Ask whether the quote protects materials, fixtures and equipment intended for your building, and separate those from your contractor’s tools. 4

Who Needs Builders Risk Insurance?

You need it if you own the project or your contract makes you responsible for it. Agree with the owner and contractor on who buys the policy, so the project isn't insured twice or not at all. 5,2

Builders Risk Insurance Coverage Examples

What happened

Materials Are Damaged Before Delivery

Windows waiting in temporary storage are damaged before they reach your building site.

How coverage may help

Builders risk may cover materials before installation, but off-site storage and transport must be included. The contractor's tools may need different coverage. 1,4

What happened

You Open Before Construction Ends

You open the finished part of a building while contractors continue working elsewhere.

How coverage may help

Occupancy can affect when builders risk ends. Tell your broker about the phased opening so construction and finished-building coverage can be coordinated. 1,4,5

How Do You Compare Builders Risk Insurance Coverage and Costs?

Project Value and Changes

Discuss your completed project value, which costs it includes and how to report changes to the work. 5

Limits and Deductibles

Compare your proposed limits and deductibles, including how the insurer calculates any percentage deductible. 4,5

Jobsite, Storage and Transit

Your materials may wait in a supplier's warehouse, travel by truck and reach the jobsite before installation. Protection at the site doesn't carry over to storage or transit automatically, and limits can differ at each stage, so list every stage for your broker. 4

What Exclusions and Conditions Should You Check in Builders Risk Insurance?

Faulty Work and Resulting Damage

Ask how the quote treats faulty design, materials or workmanship, and damage that follows those problems. 4

The sample form excludes defective work but can still respond to damage that follows it. Replacing the faulty work and repairing the damage it caused may be paid differently. 4

Completion and Occupancy

Ask when your construction coverage starts and ends, and how completion, acceptance or occupancy affects it. 4,5

If you open part of the building while work continues, coverage can end for that part. Tell your broker about phased openings and schedule changes before they happen. 4,5

How Does Builders Risk Insurance Compare With Related Coverage?

Project Property and Liability

Review damage to your construction project separately from claims that someone was injured or their property was damaged. 1,3

What Do You Need for Builders Risk Insurance Quotes?

Bring a project description, location, work completed so far and expected construction schedule to your quote discussion. 5,2

Frequently Asked Questions About Builders Risk Insurance

Are Tools and Building Materials Treated the Same?

No. Windows awaiting installation and a contractor's drill may be insured differently, so check each. 4

When Does Builders Risk Coverage End?

On the date and conditions the policy sets; completion, acceptance or occupancy can end it earlier. 4,5

What Project Value Should I Use for Builders Risk Insurance?

The completed value of the project. Ask which costs belong in it and how to report change orders so the amount insured keeps up. 5

How Is a Builders Risk Percentage Deductible Calculated?

As a percentage of a base the policy defines, and program wordings use different bases. Ask the broker to turn each quote's percentage into the dollar amount you would pay. 4,5
