How builders risk works.

The named insured is the single most consequential choice on a builders risk policy. Here is what that choice controls.

An owner-controlled policy names you, the owner, as the first named insured, with the general contractor and subcontractors added as additional insureds. You hold the policy, you control it, and the coverage sizes to your finished home. A contractor-controlled policy inverts all three: the contractor holds it, controls the claim, and sizes it to their contract. If the relationship sours or the contractor walks, so does the policy.

Your construction lender will also appear, as a loss payee or mortgagee. That is expected and required by the loan. It does not change who controls the policy, only who gets paid alongside you on a loss.

Good builders risk is written on a special form (open perils) basis: it covers direct physical loss from any cause except the ones the policy names. That makes the exclusions the whole story, because everything not excluded is in.

The two most common gaps are flood and earthquake. Both are standard exclusions, and both can be added by endorsement. On a coastal or seismic site, adding them is not optional in any real sense.

The subtler exclusion is faulty workmanship, design, and materials. If a wall is built wrong and has to be torn out, the policy does not pay to redo the defective work. What it may pay for is the resulting damage: if the faulty work causes a covered loss elsewhere, the ensuing damage can be covered even though the defect itself is not. Where that line falls depends on the exclusion's wording, and the wording varies, so it is worth knowing which version your policy carries before a loss tests it.

The remaining standard exclusions are wear and tear, mechanical breakdown, and employee theft. None are surprising. Confirm them anyway.

A covered loss is settled on the cost to repair or replace the damaged work, up to your limit and after the deductible. A partial loss pays the cost of the damaged portion; a total loss pays the value in place when it happened, up to the completed value you declared.

The completed-value form carries one advantage in your favor: it does not impose a coinsurance penalty. Because you declared the full finished value up front, a partial loss is not scaled down for underinsurance the way a policy with a coinsurance clause would scale it. You collect the repair cost, not a fraction of it. The form still caps you at the number you declared, so setting that number right is what keeps a large loss from outrunning the limit.

Builders risk is a term policy sized to the construction schedule, commonly written for twelve months with the option to extend. The extension is the trap. If the build runs long, which custom builds do, and the term expires before you extend it, coverage lapses at the worst possible moment: a nearly finished house with no policy over it. Track the expiration against the schedule and extend early, not at the deadline.

Coverage also ends on its own terms, at the earliest of completion, occupancy, or expiration. Watch occupancy most closely. Moving in, even partially, can terminate coverage before you think it has, because the policy reads the building as finished and in use. That endpoint is exactly where your homeowners policy has to take over, and coordinating the two is its own subject. Builders risk vs. homeowners covers the handoff.

How much coverage to declare is the sizing question: how much builders risk you need. What it costs to carry this coverage for the length of the build is the pricing question: what builders risk costs.
