Every party on a construction site has skin in the game. The owner has capital committed to the project. The general contractor has a contract, a schedule, and a reputation riding on the project’s successful completion. Each subcontractor has crews, materials, and equipment sitting on-site that they won’t be paid for until the work is done. But in most cases, only one insurance policy protects the physical structure itself while it’s under construction. It’s easy for everyone involved to assume someone else already has that covered.
That assumption is a common and expensive misunderstanding on an active job site.
What Does Course of Construction Insurance Cover?
Course of construction insurance, also called builder’s risk insurance, protects a project against physical loss or damage while it’s being built. Covered perils typically include fire, wind, materials theft, and vandalism. Coverage generally runs from the start of construction until the owner takes occupancy or the policy period ends, whichever comes first.
Standard commercial property insurance, on the other hand, covers a finished, occupied structure.
As the III’s overview of what a business owners policy covers explains, it protects “your building or office space, as well as property owned by your business.” That is the description of a finished building, not one in progress. A structure that’s half-framed, with materials staged across multiple floors and its value changing week to week, doesn’t fit that model. Course of construction coverage exists specifically to protect a project during the stretch when standard property insurance doesn’t apply.
Named Insured vs. Additional Insured: What’s the Difference?
Here’s where the multi-party problem starts. Most course of construction policies name only one party, usually the owner or the general contractor, as the named insured. The NAIC’s glossary defines a named insured as “the individual defined as the insured in the policy contract.” Coverage runs to whoever is actually listed on the policy, not to everyone with labor or capital riding on the outcome.
Subcontractors are not automatically covered simply because they’re on the job site. Depending on how the policy is written, subs may be added as additional insureds or scheduled by name. Some policies use broader language that extends protection to contractors and subcontractors. If the policy includes none of that language, a sub’s materials and work in progress aren’t protected. That’s true no matter how central their work is to the project.
This is easy to miss because a subcontractor’s own general liability policy is doing something different. GL coverage responds when a sub’s work causes injury or damage to someone else. It doesn’t protect a sub’s materials or labor if the structure itself is damaged by fire or storm before the project is complete. That protection, if it exists for a sub at all, comes from the course of construction policy. It only applies if the sub is actually named on it.
When a Fire Brings the Coverage Structure to Light
Picture a mid-size commercial build. Framing is complete, and an electrical subcontractor is midway through rough-in work. An overnight electrical fire damages framing on two floors and destroys equipment and materials the electrical sub had left on-site.
The owner assumed the general contractor’s course of construction policy covered the entire project, structure, and all trades included. The general contractor’s policy does respond, but it names only the owner and the general contractor as insureds; the electrical sub was never added. The sub assumed their own general liability policy would cover the loss. That policy only responds to claims involving harm to third parties, not damage to their own equipment and materials from a covered peril. None of the policies in place actually names the sub for this kind of loss.
The framing damage gets addressed under the course of construction claim. The project timeline slips. The electrical sub absorbs the cost of replacing their own materials and equipment out of pocket. They discover the coverage structure only after the fire, not before it.
What to Confirm with your Course of Construction Policy Before You Break Ground
None of this requires a more expensive policy. It requires knowing, in advance, who the course of construction policy explicitly names.
Ask to see the declarations page of the policy itself, not just a certificate of insurance, and confirm exactly who’s listed as an insured. Address it directly in the construction contract. Specify which party is responsible for securing the course of construction policy. Require that subcontractors either be added to it or carry their own coverage for materials and equipment staged on-site. Revisit the question any time the project changes: new subs come on board, a new phase begins, or a lender joins the project. Lenders are frequently added as loss payees, and that addition can affect how a claim gets paid.
The SBA’s guidance on securing business insurance has a simple premise: coverage doesn’t exist because a project is underway. It exists because someone specifically arranged it. On a job site with an owner, a general contractor, and a rotating group of subcontractors, that arrangement has to be explicit. It can’t be assumed by any one of them.
A review of the course of construction policy before the first shovel goes into the ground costs nothing. It can prevent a dispute that otherwise surfaces only after a loss. Meslee works with owners, general contractors, and subcontractors to confirm the right parties are actually protected before work begins, not after.
