What Is Builder's Risk Insurance? The Coverage That Protects a Project Under Construction
Builder's risk insurance — also called course of construction insurance — is property insurance specifically designed for buildings under construction. It covers the structure itself, the materials stored on or near the site, and sometimes soft costs like additional interest, rental income lost during delays, and redesign fees. The coverage runs from the start of construction through substantial completion, when the project transitions from 'under construction' to 'occupied building' and shifts to conventional property insurance.
Builder's risk is both essential and often overlooked. Essential because a catastrophic loss on a large construction project can easily reach eight or nine figures; overlooked because most of the time the policy sits dormant, nothing happens, and the project finishes uneventfully. The combination produces a predictable pattern: teams that invest in understanding builder's risk coverage handle problems smoothly when they arise; teams that don't find out the hard way what their coverage actually did (and didn't) provide.
Builder's risk is typically written as a 'special form' or 'all-risk' policy, meaning it covers all direct physical loss to covered property except for specifically excluded causes. The key coverages:
Typical builder's risk coverages
- The structure being built — direct physical loss to the building itself
- Permanent fixtures and equipment installed or to be installed in the building
- Construction materials on site and in transit (within defined radius)
- Temporary structures — scaffolding, forms, job trailers (varies by policy)
- Fire, theft, vandalism, lightning, windstorm, hail
- Water damage (usually excluding flood and sewer backup — see exclusions)
- Collapse from covered perils
- Additional coverages — debris removal, protection of property, pollution cleanup (all with sub-limits)
Builder's risk covers most perils but excludes some that are operationally significant. These exclusions are where claims typically get disputed and where coverage gaps most often surface unexpectedly.
Common builder's risk exclusions
- Flood — specific flood coverage must usually be purchased separately, especially in SFHA (special flood hazard areas)
- Earthquake — often a separate endorsement
- War and terrorism — typically excluded, with terrorism coverage available as endorsement
- Contractor error and faulty workmanship — the error itself isn't covered, though resulting damage may be
- Wear and tear, corrosion, mechanical breakdown
- Employee dishonesty and theft — usually excluded or sub-limited
- Soft costs — unless specifically endorsed (see below)
- Property off-site beyond the covered radius — materials stored at a supplier's warehouse may need separate coverage
The 'faulty workmanship' exclusion is frequently misunderstood. The error itself isn't covered (if a sub installs a roof wrong, the cost of reinstalling isn't covered), but resulting physical damage often is (if the faulty roof leaks and damages interior finishes, the interior damage may be covered). The policy language matters — 'ensuing loss' provisions affect how this exclusion plays out in practice.
Soft costs are project expenses that would be incurred in addition to the physical reconstruction if a covered loss delays the project. These include additional loan interest carried during the delay, additional construction loan fees, architectural and engineering redesign fees, permits re-pulled, legal and accounting costs associated with the loss, and in some cases lost rental income for the owner.
Standard builder's risk policies don't automatically cover soft costs. Adding a soft costs endorsement is common on projects where the financing structure creates meaningful carrying cost during a delay. For a project with a $50M construction loan, three months of delay after a fire could easily generate $750K+ of additional interest alone — real money that either the soft costs endorsement covers or the owner absorbs.
The contract specifies who obtains builder's risk — either the owner or the GC. Both patterns are common; each has implications.
Owner-obtained vs. GC-obtained builder's risk
- Owner-obtained — owner controls the policy, selects the carrier, and names parties insured; common on large commercial projects where the owner has an insurance broker relationship
- GC-obtained — GC controls the policy and names owner and subs as additional insureds; common on smaller projects or when the GC has better access to pricing
- Wrap-up program — single policy covers the GC, all subs, and the owner; common on very large projects through controlled insurance programs (OCIP or CCIP)
Regardless of who obtains coverage, the policy should name all parties with an insurable interest — owner, GC, lender, and key subs. Failure to name a party can produce gaps at claim time.

Builder's risk limits are typically set at the full completed value of the project plus stored materials. A $15M construction contract might have a $16-$17M policy limit to cover the full construction value plus additional soft costs. The deductible varies widely — $25,000 to $100,000 is common on commercial projects; larger on catastrophic perils (windstorm in coastal areas, earthquake in seismic zones).
The policy term runs from project inception (often defined as the start of actual construction, not site mobilization) through a specific completion milestone — usually substantial completion, though some policies extend to final completion or beyond. The termination point matters because it's the transition from builder's risk coverage to permanent property insurance, and the handoff has to be seamless to avoid a coverage gap.
Builder's risk is one of several coverages on a typical construction project, and it's important to understand where it fits relative to the others.
How builder's risk compares to other construction insurance
- General liability — covers third-party bodily injury and property damage (e.g., injuring someone on the site); builder's risk covers the project's own property
- Workers' compensation — covers employee injuries; unrelated to builder's risk
- Auto liability — covers vehicles on the project; separate from builder's risk
- Performance and payment bonds — guarantee project completion and sub payment; not insurance in the property-coverage sense
- Permanent property insurance — covers the building after completion; builder's risk ends where permanent property coverage begins
When a covered loss happens, the claim process follows a specific sequence. Notify the insurer immediately (most policies require prompt notice, with 'prompt' defined in days). Secure the site to prevent further damage. Document the loss thoroughly with photographs and written records. Assemble supporting documentation — the original contract, the SOV, progress pay applications to date, material invoices, labor records.
The insurer's adjuster investigates, typically with a cause-and-origin expert if the loss is significant. The adjuster's initial position may differ from the contractor's assessment, and negotiation is common. On large claims, the process can extend for months between initial notice and final settlement. Maintaining the documentation throughout the project — not just at claim time — is what makes the eventual claim workable.
Recurring builder's risk issues
- Coverage lapse between substantial completion and permanent property insurance inception
- Additional insured parties not named, creating disputes about who can file claims
- Flood or earthquake exclusion in high-hazard areas without separate coverage
- Stored materials off-site without specific coverage endorsement
- Temporary structures (trailers, scaffolding, forms) not covered in policy definition
- Soft costs not covered when financing structure requires it
- Deductible too high for the contractor's balance sheet — catastrophic deductible on a smaller loss wipes out project margin
Builder's risk is the project-specific property insurance that protects a construction job from catastrophic loss during construction. The coverage is broad but has specific exclusions that matter in practice — flood, earthquake, faulty workmanship, soft costs. Understanding what the policy actually covers, who's named, where the coverage begins and ends, and how claims work is part of every responsible contractor's project-start discipline. Starting a project without understanding the builder's risk policy is starting with a major category of risk unmanaged.
