What Is Builder's Risk Insurance?

Builder's risk insurance covers a building while it's being constructed or renovated — including the structure, materials, and supplies on site — against risks like fire, theft, vandalism, and wind. It's temporary coverage that lasts only through the construction period, then converts to a standard property policy once the project is complete. Contractors and real estate investors doing ground-up or rehab work need it; a finished-building policy won't cover a project mid-build.

What it covers

What does builder's risk cover?

Builder's risk covers the project itself — the structure going up or being renovated, plus the materials and supplies tied to it — against the things that go wrong on a jobsite. A fire, a windstorm, or a theft of staged materials mid-build is the kind of loss it's built for. Some policies also extend to materials in transit or storage, and to “soft costs” like delay-related fees.

CoveredExamples
The structure under constructionThe building being built/renovated
Materials & supplies on siteLumber, fixtures staged for install
Materials in transit/storage(Often) materials en route to the site
Damage from fire/wind/theftA fire or storm mid-build; jobsite theft
(Sometimes) soft costsLost interest, fees from delays

Who needs builder's risk?

Anyone with a financial stake in a project that's mid-construction. General contractors carry it for ground-up builds and major renovations. Real estate investors carry it for rehab and flip projects, where a half-finished property isn't yet a finished building a property policy would insure. Property owners building or renovating carry it — or require it of their contractor — to protect the money already in the ground. The party with financial interest in the project usually carries or requires the coverage.

When does builder's risk start and end?

Coverage starts at the beginning of the project — often at the point materials are delivered to the site — and ends at completion or occupancy, when a permanent property policy takes over. That handoff is where people get burned: if the builder's risk policy lapses before the permanent policy is in force, a loss in the gap is uncovered. Lining up the end of one with the start of the other is a classic, avoidable mistake — we set the dates so there's no open window.

The distinction

Builder's risk vs. general liability vs. a finished property policy

These three get confused constantly, but they cover three different things at three different times in a project's life. Builder's risk covers the PROJECT itself while it's being built. General liability covers injury or damage you cause OTHERS during the work. A finished property policy covers the building once it's DONE. You need the first while you build, the second the whole time, and the third once the keys turn — and no single one of them fills in for the others.

How much does builder's risk cost?

Builder's risk is usually priced as a percentage of the project's total completed value, driven by what you're building, how long it'll take, and the materials involved. A short interior remodel and an 18-month ground-up build don't price the same. The fastest path to a real number is a quote on the actual project.

FAQ

Builder's risk insurance FAQs

Does my contractor's GL cover the building I'm constructing?
No. GL covers third-party injury/damage from your operations. The structure under construction itself is covered by builder's risk.
Do I need builder's risk for a renovation, or just new construction?
Often both — major renovations and rehabs typically need it, not just ground-up builds. The right answer depends on the project.
Who buys builder's risk — the owner or the contractor?
Either, depending on the contract — whoever has the financial risk in the project. It's frequently specified in the construction contract.
