Builder's Risk vs CGL: Two Different Construction Insurance Policies That Cover Different Things
Construction projects carry two distinct types of insurance: Builder's Risk (BR) and Commercial General Liability (CGL). They sound similar but cover fundamentally different things. Builder's Risk is first-party coverage — it protects the project itself against damage or loss during construction. CGL is third-party liability coverage — it protects against claims by others for bodily injury or property damage caused by the work.
Confusion between these policies causes coverage gaps and claim denials. Understanding what each covers, who's insured, and where gaps exist is essential construction risk management. This post covers the distinction.
Builder's Risk covers the project itself:
Builder's Risk coverage
- Structure under construction
- Materials on site
- Materials in transit or storage
- Temporary structures
- Damage from fire, wind, theft, vandalism
- Covered perils per policy form
- Named perils or all-risk forms
Builder's Risk pays when the project itself is damaged. Fire destroys completed work, windstorm blows over walls, theft removes materials — BR pays for replacement. First-party coverage means the insured's own property is covered.
CGL covers liability to others:
CGL coverage
- Bodily injury to third parties
- Property damage to property of others
- Personal and advertising injury
- Products-completed operations (after project complete)
- Defense costs for covered claims
- Various exclusions
CGL pays when someone else sues. Worker falls and sues for injury, truck damages adjacent building, neighbor claims damage from construction — CGL responds. Third-party coverage means the insured's liability to others is covered.
Clear distinction:
BR vs CGL distinction
- BR covers damage to the work itself
- CGL covers liability to others for injury/damage
- BR is property insurance
- CGL is liability insurance
- BR pays insured for their loss
- CGL pays others who claim against insured
The fundamental difference: BR protects the project; CGL protects against claims arising from the work. Both are needed. Neither substitutes for the other.
BR carrier varies by project:
Builder's Risk carrier
- Owner typically — owner's interest in project
- Contractor sometimes — especially design-build
- Either carries, other is named insured
- Named insureds include owner, GC, subs (typical)
- Contract specifies who carries
- Insurable interest — party with financial stake
Builder's Risk typically carried by owner since owner has permanent interest in the property. Contractor-carried BR common on design-build. Contract specifies who carries and who's named insured. All major parties with financial interest should be named.
Coverage periods differ:
Coverage periods
- Builder's Risk — construction period only
- CGL — usually annual policy
- BR ends at specific event (substantial completion, occupancy, certificate of occupancy)
- CGL continues after project
- Completed operations coverage important for CGL
- Occurrence policies cover events during policy period
- Claims-made policies cover claims during policy period
BR is project-specific and ends when construction ends. CGL is annual and covers events during policy period. Post-completion claims under CGL require products-completed operations coverage or appropriate continuation.
Gaps exist between policies:
Coverage gaps
- BR ends before CGL products-completed operations begins
- Soft costs (lost revenue, extended costs) often limited under BR
- Professional liability (design errors) excluded from both
- Subcontractor defaults not covered by either
- Contractual penalties typically excluded
- Pollution exclusions in both
Gaps exist. Some require additional coverage — professional liability, subcontractor default insurance, pollution coverage. Others are insurance-uninsurable (contractual penalties). Risk assessment identifies gaps; coverage additions or contractual allocation addresses them.

BR claim scenarios:
BR claim scenarios
- Fire destroys framing — BR pays for reconstruction
- Wind damages roof during construction — BR responds
- Theft of materials from site — BR covers
- Water damage from broken pipe — BR covers
- Mechanical breakdown — may be excluded
- Faulty workmanship typically excluded (LEG-3 endorsement may cover)
BR responds to sudden accidental damage to the work. Faulty workmanship (contractor's mistake) typically excluded — that's contractor's responsibility. LEG (London Engineering Group) endorsements can add coverage for damage resulting from faulty workmanship.
The critical gap is at substantial completion — Builder's Risk often ends when construction ends, but CGL products-completed operations coverage for the completed project may have timing issues. Owner's property insurance should be in place for the completed building; contractor's products-completed operations covers liability from the work. Coordinating transition prevents coverage lapses.
CGL claim scenarios:
CGL claim scenarios
- Worker falls, sues contractor — CGL (not sub's WC; third-party suit)
- Construction vehicle damages neighbor's building — CGL
- Building completed, later fails causing injury — products-completed operations
- Bystander injured by falling debris — CGL
- Contractor's employee injury — WC, not CGL
- Damage to the work itself — not CGL (expected on project)
CGL covers liability for injury or damage caused by work. Doesn't cover contractor's own employees (workers' comp handles). Doesn't cover damage to the work itself (BR or contractor responsibility). Covers others harmed by the work.
Additional insured extends coverage:
Additional insured considerations
- Owner typically named additional insured on contractor's CGL
- Subcontractors name contractor as additional insured
- Specific endorsements (CG 20 10, CG 20 33, others)
- Coverage scope varies by endorsement
- Primary and non-contributory language important
- Waiver of subrogation common
Additional insured endorsements extend CGL coverage to contractually-designated parties. Owner as additional insured on contractor's policy; contractor as additional insured on sub's policy. Specific endorsement forms have different scopes — understanding matters.
Limits and deductibles structure:
Limits and deductibles
- BR limit — typically completed project value
- CGL limits — per occurrence and aggregate
- Deductibles — BR often substantial; CGL typically lower
- Umbrella coverage over CGL
- Owner may specify minimum limits
- Adequate limits for project risk
Adequate limits matter. Under-limited coverage produces uninsured exposure in major claims. Owner contract often specifies minimums. Umbrella coverage extends CGL limits cost-effectively.
Builder's Risk and CGL are distinct construction insurance policies covering different things. BR is first-party coverage protecting the project itself during construction. CGL is third-party liability coverage protecting against claims by others. Both are needed — neither substitutes for the other. Coverage periods differ — BR ends at construction completion; CGL continues with products-completed operations. Gaps exist requiring additional coverage or contractual allocation. Additional insured endorsements extend CGL to contractually-designated parties. Adequate limits and appropriate deductibles structure coverage. Contractors understanding the distinction buy appropriate coverage and manage gaps; contractors confusing them face coverage surprises when claims arise. Insurance is contractor's risk management infrastructure — getting it right is foundational.
