§ 1What it is

Builders risk insures the thing being built. Fire, wind, theft of materials, vandalism, collapse during construction — property damage to a structure that does not yet exist as a finished building, and therefore cannot sit on a normal property policy.

It is not liability cover. If a passer-by is injured, that is general liability. If the half-built structure burns down, that is builders risk. Both, on most jobs.

§ 2Who buys it

Whoever the contract says. On residential work the owner often carries it; on commercial work the general contractor often does. What matters is that somebody does, and that everyone with an interest is named — owner, general, lender, and frequently key subs.

“The owner has it” is not a named-insured status.

If your materials burn on a policy you are not named on, you are a claimant against somebody else’s insurer, not an insured. Get named, or carry your own.

§ 3The completed-value basis

A builders risk limit is normally the completed value of the project — what the finished structure will be worth, not what has been installed so far. The premium reflects that the exposure grows through the build.

What sets the premium
InputEffectWhy
Completed valueSets the limit and most of the premiumIt is the maximum loss
Construction typeFrame costs more than masonry or steelFire exposure
Term lengthLonger builds cost moreMore time at risk
DeductibleHigher deductible, lower premiumRetained risk
LocationWind, flood and wildfire zones cost moreCatastrophe exposure

Our builders risk calculator takes completed value, term and deductible and returns the band those three imply, before location loading.

§ 4The usual gaps

Four things a standard policy usually leaves out, each of which can be added — and each of which is expensive to discover after a loss.

  • Soft costs. Extra interest, extra rent, redrawn plans, additional permits. The rebuild is covered; the delay around it is not, unless soft-cost cover is added.
  • Off-site and in-transit materials. The generator stolen from the yard before it reached the job, or off the truck.
  • Faulty workmanship. The bad work is excluded; resulting damage to other property may not be — read the wording, this varies more than any other clause.
  • Water and earth movement. Flood and earthquake are usually separate, in every zone.

§ 5When it ends

A builders risk policy terminates on an event, not just on a date: occupancy, acceptance, or the expiry of the term — whichever comes first. Partial occupancy of a finished wing while the rest is under construction is the classic trap; some wordings end cover for the whole project at that moment.

Two dates need to meet: the day builders risk ends and the day the permanent property policy begins. Any gap is uninsured, and a project handed over on a Friday with a policy starting Monday is a real, and common, three-day hole.
