# Builder's Risk Insurance: A Complete Guide for Construction Projects
Builder's risk insurance is one of the most misunderstood coverages in construction. It's not the same as general liability. It doesn't cover worker injuries. And it's frequently structured incorrectly — either over-insured, under-insured, or missing critical coverage extensions that become relevant only when a loss occurs.
This guide covers what builder's risk is, who needs it, how it works, and what to watch for when buying it.
What Is Builder's Risk Insurance?
Builder's risk (also called "course of construction" insurance) is a property insurance policy covering a structure under construction against physical damage. Where GL protects you from third-party claims, builder's risk protects the property itself.
During construction, a building is uniquely vulnerable: the structure isn't complete, security may be limited, fire protection systems aren't active, and exposures like open roofs and unprotected framing create risks that don't exist in a finished building.
Builder's risk fills the property insurance gap during the construction period.
What Builder's Risk Covers
A standard builder's risk policy covers:
The structure itself: Physical damage to the building or structure under construction from covered perils — fire, lightning, windstorm, hail, explosion, vandalism, theft, and (depending on the form) water damage.
Materials on-site: Building materials and equipment that have been delivered to the site but not yet incorporated into the structure.
Materials in transit: Many builder's risk policies extend to cover materials in transit to the project site from the supplier's facility.
Temporary structures: Site trailers, scaffolding, temporary fencing, and other temporary structures used in connection with the project.
Debris removal: The cost of removing debris after a covered loss.
What Builder's Risk Does NOT Cover
Standard exclusions:
- **Earthquake**: Almost universally excluded from standard builder's risk; requires a separate endorsement or policy
- **Flood**: Standard exclusion — requires separate flood coverage or endorsement (especially important in FEMA flood zones)
- **Employee theft and dishonesty**: Requires a crime endorsement or separate crime policy
- **Contractor's equipment**: Heavy equipment, tools, and machinery owned by the contractor (requires contractor's equipment floater)
- **Mechanical breakdown**: Damage to equipment from mechanical or electrical breakdown
Design defect exclusion: Builder's risk does not cover losses resulting from faulty design, workmanship, or materials. It covers damage to the project from external perils, not from construction defects.
Who Should Carry Builder's Risk?
This is where confusion is most common. The answer is: it depends on the project contract.
Project owners typically carry builder's risk on owner-funded projects, because they bear the economic risk of project damage. If a building under construction burns down, the owner has lost their investment.
General contractors may be required to carry builder's risk by the project contract, particularly on contractor-financed design-build projects where the GC has economic risk in the structure.
Lenders often require builder's risk as a loan condition for construction loans, with the lender named as a loss payee on the policy.
On many projects, the contract specifies who is responsible for builder's risk — read your contract carefully before assuming you or your client has it covered.
Coverage Amounts: Completed Value vs. Reporting Form
Completed value basis: The policy is written for the full completed value of the project at the outset. This is the most common approach for residential and smaller commercial projects. Premium is calculated on the full value even though coverage is only needed during construction.
Reporting form / monthly value: The insured reports the current value of work in place each month, and premium adjusts accordingly. Better for long projects where value builds slowly.
Soft Costs Coverage
One of the most valuable — and most overlooked — extensions to builder's risk is soft costs coverage. If a covered loss delays project completion, soft costs coverage reimburses:
- **Loan interest** during the delay period (often the biggest number)
- **Additional architect, engineering, and consultant fees** for redesign and reconstruction oversight
- **Permit fees** that must be re-obtained after a loss
- **Real estate taxes** during the extended construction period
- **Marketing and leasing costs** for delayed income-producing properties
On a $20M commercial development, a 6-month delay can produce $500,000+ in soft costs. This coverage is typically available for an additional 1–2% of the base premium — an excellent value.
When Does Coverage Begin and End?
Builder's risk coverage typically begins on the first day of construction (or delivery of materials to the site) and ends at the earliest of:
- The date of substantial completion or occupancy
- The date the owner accepts the project
- A defined number of days after construction is complete
There's an important gap to watch for: most builder's risk policies contain an occupancy or completion clause that terminates coverage as soon as the property is occupied or accepted — even if technically not complete. Understand this trigger in your policy before you have keys-in-hand.
Builder's Risk for Renovation Projects
Renovation projects require special attention. A builder's risk policy covering only the new construction scope doesn't protect the existing structure. If a renovation contractor starts a fire that damages the existing building, the builder's risk policy may deny the claim if the existing structure isn't scheduled.
For renovation projects, ensure your policy clearly covers:
- The existing structure (may require the owner's property policy to be endorsed)
- The renovation scope (builder's risk)
- How the two policies coordinate at loss time
How to Buy Builder's Risk
Builder's risk is typically sold by:
1. The contractor's insurance broker as an endorsement to their existing program
2. As a standalone project policy from a specialty insurer
3. As part of an OCIP or CCIP program
For large or complex projects, a standalone builder's risk policy from a specialty insurer often provides broader coverage and higher limits than an endorsement to an annual policy.
Pricing is based on the completed project value, type of construction, location, project duration, and coverage extensions required.
