Coverage A commercial general liability is the section of a CGL policy that pays for third-party bodily injury and property damage. For general contractors, it is the single most important coverage section on any subcontractor's insurance certificate. ISO data from 2024 shows that 78% of all CGL claims in construction trigger Coverage A. The other two coverage parts (B and C) handle far less frequent exposures.

This guide breaks down what Coverage A covers, how occurrence triggers work in construction, why products-completed operations matter, and how to read Coverage A on a sub's certificate of insurance.

What Coverage A Actually Covers

Coverage A on the standard ISO CGL form (CG 00 01) applies to two categories of harm.

Bodily injury. Physical injury, sickness, disease, or death sustained by a third party. In construction, this means a pedestrian hit by falling debris, a building occupant injured by construction dust, or a property owner who slips on a sub's work area.

Bodily injury does not include injuries to the sub's own employees. Workers' compensation handles those claims separately.

Property damage. Physical injury to tangible property or loss of use of tangible property that has not been physically injured. A sub's backhoe cracking a neighbor's foundation is physical injury to property. Shutting down a business because a sub's work blocked the entrance is loss of use.

Coverage A Element	What It Means	Construction Example
Bodily injury	Physical harm to a third party	Falling tool injures a pedestrian
Property damage - physical	Tangible damage to property	Excavation cracks adjacent building foundation
Property damage - loss of use	Cannot use property due to insured's operations	Water main break floods neighboring business
Products-completed operations	BI/PD occurring after work is finished	Installed HVAC system leaks, damages ceiling 6 months later

How Occurrence Triggers Work in Construction

Coverage A on most CGL policies uses an occurrence trigger. This means the policy in effect when the injury or damage happens responds to the claim, regardless of when the claim is filed.

Example. A plumbing sub installs a water line in March 2025. The line ruptures in November 2025, flooding the floor below. The sub's CGL policy that was active in November 2025 (when damage occurred) is the responding policy.

This matters for GCs because construction defects often surface months or years after work completion. The occurrence trigger ties the claim to the date of damage, not the date of work.

Claims-made alternative. Some specialty contractors carry claims-made CGL policies, which cover claims filed during the policy period. If a sub switches insurers or lets coverage lapse, a claims-made policy creates a gap. The old policy only covers claims filed while it was active. The new policy may not cover incidents that happened before its effective date.

GCs should require occurrence-based CGL from every subcontractor. If a sub carries claims-made coverage, require a retroactive date that predates their first day on your project and an extended reporting period (tail coverage) of at least three years.

Products-Completed Operations: Why It Matters

Products-completed operations is a component of Coverage A that covers bodily injury or property damage arising from work the sub has finished. It is not a separate coverage part. It falls under Coverage A, but it carries its own aggregate limit.

When work is "completed." Under the ISO form, work is complete when all contracted work at the job site is finished, or when the portion of work at one project site is put to its intended use. If a sub finishes their scope on Building A but still has work on Building B, their Building A work is "completed" for insurance purposes.

Why GCs care. A 2024 Zurich Construction Risk Engineering study found that 34% of CGL claims against subcontractors arise from products-completed operations. A roof that leaks after final inspection, a weld that fails under load six months later, or an electrical installation that causes a fire after occupancy all trigger products-completed operations coverage.

The sunset clause problem. Some insurers limit products-completed operations to two or three years after project completion. Given that construction defect statutes of repose run six to twelve years in most states, a short sunset clause leaves years of uncovered exposure.

State	Statute of Repose (Years)	Typical Sunset Clause	Gap
California	10	2-3 years	7-8 years uncovered
Texas	10	2-3 years	7-8 years uncovered
Florida	10	2-3 years	7-8 years uncovered
New York	6	2-3 years	3-4 years uncovered
Illinois	10	2-3 years	7-8 years uncovered

Require products-completed operations coverage that runs through the applicable statute of repose, or at minimum five years after substantial completion.

Coverage A Exclusions GCs Must Understand

The ISO CGL form contains 15 standard exclusions under Coverage A. Several are directly relevant to construction.

Exclusion a: Expected or intended injury. Coverage A does not pay for damage the insured expected or intended. Deliberately damaging a competitor's work voids coverage.

Exclusion j: Damage to property. Coverage A does not cover damage to the insured's own work. If a drywall sub damages their own finished walls during subsequent work, Coverage A does not respond. This exclusion has a subcontractor exception: if damage to the insured's work results from work performed by a subcontractor, Coverage A does apply. This exception matters for GCs who hire subs to perform portions of the GC's own scope.

Exclusion l: Recall of products. If a defective product must be recalled, Coverage A does not pay for the recall itself. It does cover bodily injury or property damage caused by the defective product before recall.

Exclusion - your work. Coverage A excludes damage to the insured's completed work. The subcontractor exception in the standard form carves back coverage when a sub (not the insured's own crew) performs the faulty work. Always verify this exception is intact on the sub's policy.

How to Read Coverage A on a Sub's COI

Follow these steps to verify adequate Coverage A on a subcontractor's certificate of insurance.

Step 1: Confirm CGL is listed. On the ACORD 25, the "Commercial General Liability" box must be checked. Look for form number CG 00 01 or CG 00 02 in the policy description.

Step 2: Verify occurrence trigger. The "Occur" box should be checked, not "Claims-Made." If claims-made is checked, request the retroactive date and extended reporting period documentation.

Step 3: Check per-occurrence limit. The "Each Occurrence" limit should meet your contract minimum. Industry standard for commercial projects is $1,000,000.

Step 4: Check general aggregate. The "General Aggregate" should be at least $2,000,000. This is the maximum the policy pays for all Coverage A claims in a policy period.

Step 5: Verify products-completed operations aggregate. This appears as a separate line item on the ACORD 25. Confirm it shows at least $2,000,000 and is not excluded.

Step 6: Check for restrictive endorsements. Request the policy's endorsement schedule. Look for any endorsements that add exclusions for construction, specific operations, or specific project types. Endorsements like CG 21 39 (contractual liability limitation) or CG 22 94 (residential work exclusion) can gut Coverage A protection.

Step 7: Confirm additional insured status. Your company should be named as additional insured for both ongoing operations (CG 20 10 or equivalent) and completed operations (CG 20 37 or equivalent).

We built SubcontractorAudit to automate every step in this verification process. The platform reads ACORD 25 forms, flags missing or inadequate Coverage A limits, detects restrictive endorsements, and alerts you to claims-made policies that need retroactive date verification.

Coverage A Limits: How Much Is Enough?

The right Coverage A limit depends on your project's risk profile.

Residential remodeling ($100K-$500K projects). $1M per occurrence / $2M aggregate covers most exposures. Average bodily injury claim in residential construction runs $42,000 according to 2024 CNA insurance data.

Commercial construction ($1M-$25M projects). $1M per occurrence / $2M aggregate with a $5M umbrella policy. Property damage claims on commercial sites average $127,000.

Large-scale infrastructure ($25M+ projects). $2M per occurrence / $4M aggregate with $10M umbrella. Catastrophic bodily injury claims on infrastructure projects have reached $8M to $15M in recent settlements.

Aggregate adequacy. A sub working on multiple projects simultaneously shares their aggregate across all of them. If a sub has already used $1.5M of their $2M aggregate on other claims, only $500,000 remains for your project. Request loss runs for the current policy period to check aggregate erosion.

Frequently Asked Questions

Does Coverage A cover faulty workmanship itself? No. Coverage A covers damage caused by faulty workmanship, not the cost to repair or redo the faulty work itself. If a sub's defective concrete pour causes a structural crack in an adjacent wall, Coverage A pays for the wall repair but not for replacing the concrete pour.

What is the difference between Coverage A and Coverage B? Coverage A handles bodily injury and property damage. Coverage B handles personal injury (defamation, false arrest) and advertising injury (copyright infringement in ads). Construction claims overwhelmingly fall under Coverage A. Coverage B claims in construction are rare.

Can a GC be sued under a sub's Coverage A? Yes, if you are named as additional insured on the sub's CGL policy. Additional insured status gives you the right to tender claims to the sub's insurer for liability arising from the sub's work. Without it, you must rely on your own CGL policy.

What triggers Coverage A on an occurrence policy if damage is gradual? Courts apply different theories. The most common approach ties coverage to the policy period during which damage actually manifests. For continuous damage (like a slow water leak), some jurisdictions allow all policies in effect during the damage period to share responsibility.

Does Coverage A apply if the sub's employee is injured? No. The employer's liability and workers' compensation exclusion removes Coverage A protection for injuries to the insured's own employees. Workers' compensation insurance handles those claims. Coverage A only responds to injuries to third parties.

How often should I reverify Coverage A on a sub's policy? At minimum, verify at contract signing, at policy renewal, and at any mid-term policy change. For long-duration projects, quarterly verification catches aggregate erosion problems and mid-term endorsement changes. Automated platforms can monitor coverage continuously and alert you to any changes.
