A house under construction is not a house yet, and that distinction matters enormously to insurers. Until a structure is finished and occupied, standard homeowners and commercial property policies either exclude it or restrict coverage severely. Builders risk insurance fills that window, and knowing when it starts and stops is the difference between a covered loss and an expensive argument.
Builders risk insurance is a specialized property policy that covers a building while it is being constructed, renovated, or remodeled. It protects the structure itself along with the materials, fixtures, and equipment that will become part of it. Some carriers call it course of construction coverage, which describes the purpose more literally: it is in force only during the course of the work.
The policy typically pays for direct physical loss to the project from covered causes such as fire, lightning, wind, hail, vandalism, theft of materials, and vehicle impact. It usually extends to materials stored on site, in transit, and at temporary off-site locations, subject to sublimits. On a Florida project, wind and hail coverage deserves special attention, because some builders risk forms exclude named windstorm or apply a separate percentage deductible during hurricane season.
Just as important is what builders risk does not do. It is not liability insurance. If a subcontractor falls off a ladder or a delivery truck backs into a neighbor's fence, that is general liability and workers' compensation territory. Builders risk answers only for damage to the project itself and to the property that will become part of it.
Either the property owner or the general contractor can purchase builders risk insurance, and the construction contract usually dictates which. On custom homes, the owner often buys it because the owner holds title to the land and the improvements as they go up. On commercial projects and spec builds, the general contractor frequently carries it and folds the cost into the project budget.
What matters more than who writes the check is who appears on the policy. The owner, the general contractor, and the construction lender all have an insurable interest in the project, and all three typically need to be named. A lender financing the build will almost always require evidence of builders risk with itself listed as mortgagee or loss payee before releasing draws. Subcontractors are generally not named insureds; they carry their own liability and equipment coverage.
Confusion over who bought the policy is one of the most common gaps in residential construction. An owner assumes the builder has it, the builder assumes it was rolled into the owner's coverage, and neither confirms in writing. Before ground is broken, get a certificate of insurance in hand and read the named insured line.
Coverage centers on the structure and everything intended to become part of it. Most forms include the following, though limits and conditions vary by carrier:
Common exclusions include faulty workmanship and defective design, wear and tear, mechanical breakdown, employee theft, earthquake and flood unless added, and losses that occur after the project is occupied or put to its intended use. The faulty-workmanship exclusion causes the most disputes. If a poorly installed valve floods a floor, many forms exclude the cost to correct the bad work but will pay for the resulting water damage. That distinction is worth reading carefully in the actual policy language rather than assuming.
Builders risk limits are based on the completed value of the project, not the current value at any given moment. If a home will cost $600,000 to build, the limit should be $600,000 even though only a foundation exists on day one. Setting the limit at the completed value is what keeps the coinsurance clause satisfied and avoids a penalty at claim time.
Land value is excluded from that figure, and so is the value of existing structures on renovation projects, which are usually insured separately under the owner's property policy. Premium is generally expressed as a rate per hundred dollars of completed value and is influenced by construction type, location, wind exposure, project duration, and whether the site has fencing, lighting, and security.
In Florida, coastal proximity and roof design drive a meaningful share of the cost. Masonry construction with hurricane straps and impact-rated openings prices better than wood frame in the same ZIP code. Projects running through June to November may face a separate named-storm deductible expressed as a percentage of the completed value, so a $600,000 build with a 5 percent wind deductible carries a $30,000 out-of-pocket exposure for hurricane damage.
This is where most gaps happen. Builders risk policies are written for a fixed term, commonly three, six, or twelve months, with the option to extend if the project runs long. But the policy can terminate earlier than the stated expiration date, and most forms list several automatic triggers.
Coverage typically ends at the earliest of: the policy expiration date, the date the property is accepted by the owner, the date a certificate of occupancy is issued, the date the building is occupied or put to its intended use, or a set number of days after construction is complete. Once one of those conditions is met, builders risk stops responding even if you have paid premium through a later date.
That means the permanent policy needs to be bound before the trigger fires, not after. On a new home, the homeowners policy should be in force the day the certificate of occupancy is issued. On a commercial building, the property policy or business owners policy should take effect at acceptance or first occupancy. Coordinate the two effective dates deliberately, and if the schedule slips, notify the carrier and request an extension before the term lapses. Carriers are far more willing to extend a policy that is still active than to reinstate one that expired.
Builders risk is one piece of a construction insurance package. General liability responds to third-party bodily injury and property damage. Workers' compensation covers employee injuries. Contractors equipment or inland marine coverage protects owned tools and machinery, which builders risk generally does not. Commercial auto covers the trucks.

Homeowners doing a major renovation face a different question: does the existing homeowners policy still apply? Many carriers restrict or suspend coverage once a home is vacant during construction or once the scope exceeds a dollar threshold. Some will endorse the existing policy for smaller remodels. For a gut renovation or an addition that opens the structure to the weather, a separate builders risk policy plus a vacancy endorsement on the homeowners policy is usually the safer arrangement. Talk to your carrier before demolition begins, not after.
Flood is worth calling out separately. Builders risk forms exclude flood almost universally, and in Florida that exclusion is not theoretical. If the site sits in a special flood hazard area, the lender will require flood coverage during construction, and a builders risk flood endorsement or a separate NFIP policy will be needed.
Does builders risk insurance cover theft of tools from the job site?
Generally no. Builders risk covers materials that will become a permanent part of the structure, not the contractor's own tools and equipment. Stolen copper wire waiting for installation is typically covered; a stolen nail gun or generator is not. Contractors need separate contractors equipment or inland marine coverage for owned tools.
Can I extend builders risk if the project runs behind schedule?
Usually yes, but you must request the extension before the policy expires and before any automatic termination trigger is met. Carriers commonly allow one or two extensions, often at an additional premium, and may ask for a status update or photos. Waiting until after expiration typically means applying for a new policy at new terms.
Does builders risk cover damage caused by a hurricane in Florida?
Only if named windstorm is included, and many builders risk forms either exclude it or apply a separate percentage deductible. Confirm the wind terms in writing before hurricane season, especially for coastal projects. Sites with open framing and loose materials are also expected to be secured ahead of a named storm, and failure to do so can affect a claim.
Who is responsible for buying builders risk on a custom home?
It depends on the construction contract. Many residential contracts assign the obligation to the owner, while others place it on the general contractor. Read the insurance article of the contract, confirm in writing who is purchasing it, and make sure the owner, contractor, and lender are all named on the policy.
What happens if I never convert to a permanent policy?
You are uninsured from the moment the builders risk termination trigger fires. If a certificate of occupancy is issued on a Friday and a fire occurs Saturday with no homeowners policy in place, there is no coverage. Bind the permanent policy to take effect on or before the day occupancy or acceptance occurs.
Builders risk insurance is short-term coverage with hard stop dates, and the most expensive mistakes happen in the gap between the last day of the construction policy and the first day of the permanent one. Map both effective dates before the project starts, confirm in writing who is buying the policy and who is named on it, and get the wind and flood terms in writing if the site is anywhere near the Florida coast. A Truscott coverage review can line up the builders risk term against your target completion date and make sure the homeowners or commercial property policy is ready to take over cleanly.

Contractual risk transfer uses indemnity clauses, additional insured status, and waivers of subrogation to move liability to the party best able to control it. Here is how those three tools work together in a business contract.
