Builder’s risk insurance is first-party property coverage on a construction project while it is being built. It pays for direct physical loss or damage to the structure and to the materials and equipment that will become part of the work. What it does not do is run until somebody remembers to cancel it. Builder’s risk ends on a set of triggers written into the form — and the one that catches projects out is a clock that starts the day anyone moves in.
This page answers the termination question on its own. For the full explainer on what builder’s risk covers, who buys it, and the endorsements that sit on top of it, see our guide to builders risk insurance. Where the two pages divide: that guide owns the coverage — what it pays for, how the value is reported, the soft-cost and defective-workmanship questions. This page owns the finish line — the trigger list, the two clocks, and the handover that has to happen before they run out.
The direct answer: coverage ends at the first trigger, not the last
Under the ISO Builders Risk Coverage Form (CP 00 20), the benchmark form most carrier wordings are measured against, coverage ends when the first of these events occurs:
- The policy expires or is cancelled.
- The property is accepted by the purchaser.
- The insured’s interest in the property ceases.
- The insured abandons the construction with no intention to complete it.
- 90 days after construction is complete — unless the insurer specifies otherwise in writing.
- 60 days after any building named in the declarations is occupied in whole or in part, or put to its intended use — unless the insurer specifies otherwise in writing.
Two things in that list do the damage. First, it is a race: whichever trigger fires first ends the coverage, even if the policy’s printed expiration date is still months away. Second, there are two separate clocks running on two different events. Ninety days runs from completion. Sixty days runs from occupancy or intended use. They are not the same date, and on most projects occupancy comes first.
One caution before you rely on the numbers: the ISO form is the reference point, not the majority. Most builder’s risk written in the United States is placed on inland marine forms, and carrier wordings vary. The 60- and 90-day figures are the standard-form benchmark — your project’s actual clocks are whatever your form says, which is why the first item on the checklist below is to read the termination clause in the policy itself, not a summary of it.
Why the 60-day clock surprises people
Partial occupancy starts the whole clock. The form’s wording is “occupied in whole or in part.” One tenant taking one floor, the owner moving staff into a finished wing, a retailer stocking shelves in one unit — any of it starts a 60-day countdown that applies to the building, not just to the occupied part. On a phased handover, the coverage on sections still under construction can expire while crews are still working in them.
Occupancy and completion are different events. A building can be occupied while punch-list work, commissioning, and fit-out continue for months. Teams track substantial completion because contracts and retainage turn on it. The builder’s risk form is watching a different milestone: use. A certificate of occupancy, a tenant improvement handoff, even putting the building to its intended use without anyone formally “moving in” can start the clock.
“Complete” is narrower than it feels. The 90-day clock runs from completion, and completion has been read by a court — in an adjacent coverage context — as the point where the physical structure is achieved, not where the operation is ready. A pending inspection or licence did not keep the project “incomplete” in that reading. In plain terms: do not assume that because the building is not yet operating, neither clock has started.
The dates drift in one direction only. Projects routinely run past their planned dates while the policy does not drift with them. That failure mode — the schedule slipping past the form — is covered in our builders risk guide, and it compounds this one: a project that finishes late and is occupied quickly can hit the 60-day trigger before anyone has looked at the policy since groundbreaking.
Who is exposed in the gap
The gap is the stretch between builder’s risk ending and the permanent property policy attaching. If a fire, water loss, or theft lands in that window, there may be no property policy in force on a finished or nearly finished building. The exposure is not evenly shared:
- The owner carries the asset risk. The building is at or near full completed value — the largest the exposure ever gets — and the owner is usually the party who must place the permanent coverage.
- The general contractor may still be working on site, with an insurable interest in the work, contractual insurance obligations still running, and its own property — tools, materials, installed-but-unaccepted work — inside a building whose coverage just ended. Contractors who assume the owner’s policy situation mirrors theirs get surprised; where contractors stand at renewal and mid-project is a recurring theme in our contractor renewal coverage.
- The lender typically requires continuous property coverage in the loan documents, and mortgagees usually sit on the builder’s risk policy as loss payees. A lapse can put the borrower in breach of a loan covenant at exactly the moment the loan is converting or the project is being refinanced — which is why the permanent policy’s effective date is a closing-table item, not an afterthought.
- Tenants moving in early bring their own property, fit-out, and business interruption exposure into a building that may be between policies — and their leases often assume coverage that nobody has verified.
On large projects the stack of parties and policies is wider still — programs, wraps, and lender requirements layered over the same handover — as the risk stack on a $430 million hospital build shows. The termination question matters there for the same reason: every layer has its own end date.
What to do before occupancy
Bind the permanent property policy before builder’s risk ends — not after. Work backwards from the earliest plausible trigger, not the planned completion date. The permanent policy should be bound and ready to attach no later than the day the builder’s risk coverage terminates, and on an occupied building the safe assumption is that the 60-day clock is already running.
Get the insurer’s written position on occupancy. Both clocks carry the same escape hatch: “unless the insurer specifies otherwise in writing.” If the project needs coverage beyond a trigger — continued work after partial occupancy is the common case — that has to be agreed in writing before the trigger fires. Where a project needs to occupy before completion, a permission-to-occupy arrangement with the carrier is the mechanism, arranged in advance rather than requested after a loss.
Check the loan documents, not just the policy. Lender requirements on the transition — required effective dates, loss payee wording, evidence of insurance at conversion — are contractual obligations separate from the form. Brokers rechecking a placement mid-term when facts have moved is standard practice; the same discipline applies at handover, and our mid-term recheck guide walks the method.
Extend deliberately if dates slip. If construction will run past the policy period or a trigger date, an extension endorsement is a purchase made while coverage is still in force. After termination, there is nothing to extend.
Assign the handover a date and an owner. Standard contract forms treat early occupancy as its own insurance event, with dedicated sections for occupancy before substantial completion — because the drafters knew this transition is where gaps are made. Treat it the same way in the project file: the transition from builder’s risk to permanent property insurance gets a calendar date and a named person responsible for it, not an assumption that someone will remember. Placing the coverage correctly starts with knowing which policy is supposed to be in force at each stage — our map of insurance policy types lays out where builder’s risk sits in that sequence.
The handover checklist
- Read the termination clause in the actual policy form on the project — confirm its occupancy and completion clocks, in days.
- Record the date any part of the building is first occupied or put to its intended use; start the occupancy clock from that date.
- Record the completion date the form would recognise; start the 90-day clock.
- Bind the permanent property policy to attach no later than the earliest trigger date.
- If any occupancy will happen before completion, get the carrier’s written consent or a permission-to-occupy arrangement in place first.
- Confirm the lender’s transition requirements and loss-payee wording against the new policy.
- If dates have slipped, buy the extension endorsement before, not after, a trigger fires.
- File the handover — trigger dates, new policy number, effective date — where the whole project team can see it.
