Builders Risk Insurance Cost: Average Rates & What Drives Them

Builders risk insurance covers a structure while it is being built or renovated. It protects materials, work in progress, and the building itself from losses such as fire, theft, vandalism, and storm damage. The policy typically ends when construction finishes and a permanent property policy takes over. Because the policy is tied to one project, it is priced against the value of that project rather than as a flat monthly fee.

This guide explains how the percentage method works, shows what the numbers look like on a real budget, and lists what moves a premium. An insurance agent or broker who works with contractors can price a specific job.

Most published estimates express the cost as a percentage of the total construction project. Insureon bases its figure on the total completed value of the structure, which includes all materials and labor but excludes the value of the land.

The three sources are close but not identical. Embroker and NerdWallet give the same band, while Insureon reports a slightly lower top end. The difference comes from who is counted and how, since each source draws on its own customers or its own cited insurer.

Percentages are easier to judge against a dollar budget. Embroker applies its range to a small renovation.

The same percentages scale with the project. A budget ten times larger moves the premium range by about the same factor, though very large projects are priced by underwriters on an individual basis and do not follow a simple percentage.

Some contractors buy builders risk as a policy of their own, and others add it to an ongoing contracting program. Insureon reports what its small-business customers pay.

The annual spread is wide because projects vary so much in value, duration, and risk.

A small remodel and a ground-up commercial build do not belong in the same pricing bracket, so the low end of this range reflects small, short jobs.

• Project value. The completed value of the structure sets the base for the premium.
• Construction type. Frame construction and masonry carry different fire risks. Insurers rate the type of structure and the materials used.
• Location. Coastal and flood-prone areas can cost more because of hurricane and flooding exposure.
• Policy length. A longer build means a longer period of exposure, and longer policies generally cost more.
• Site security. Fencing, lighting, and monitoring reduce theft and vandalism risk.
• Coverage limits and deductible. Higher limits cost more, while a higher deductible lowers the premium.
• Contractor experience. A track record of completed projects without claims can help.

Policies generally cover the building under construction, materials on site, and temporary structures. Many add coverage for items in transit or stored off site, and some include limited amounts for documents, debris removal, and delay-related costs. Equipment that moves from jobsite to jobsite is usually insured separately, under tools and equipment or inland marine coverage.

The list changes by policy, so read the inclusions and exclusions before you compare prices.

On many projects the property owner buys it. On others the general contractor does, and the construction contract spells out who is responsible. Lenders often require proof of coverage before releasing funds. Reading the contract and asking the owner, lender, and a licensed insurance agent or broker avoids a gap in coverage.

• What project value will the premium be based on?
• Is the quote for a fixed term, and what does an extension cost if the build runs late?
• What is the deductible, and does it differ for weather or theft?
• Which materials and structures are covered while they are stored off site?
• What happens to the policy when the project is finished?
