11.3 Key CGL Exclusions and Endorsements

Why the CGL Excludes So Much

The Commercial General Liability form is broad on its insuring side but narrows coverage through a long list of exclusions. Many exclusions exist because the exposure belongs in a different policy (auto, workers compensation, professional liability) or is uninsurable as a matter of public policy (intentional acts).

Exam questions test whether a loss is excluded outright, partially restored by a carve-back, or moved to a separate coverage part.

The Most-Tested Exclusions

Liquor Liability vs. Host Liquor

A frequent trap: the liquor exclusion applies only to insureds in the business of manufacturing, selling, serving, or furnishing alcohol. A tavern needs a separate liquor liability policy.

A business that merely hosts a holiday party retains host liquor liability coverage under the CGL because it is not in the alcohol business. Candidates must read the insured's occupation into the fact pattern.

Your Product and Your Work

The CGL does not pay to repair or replace the insured's own defective product or own faulty work — that is a business risk, not insurance. However, property damage to the insured's completed work is covered if the damaged work, or the work that caused the damage, was performed by a subcontractor.

This subcontractor carve-back is why general contractors require subs to name them as additional insureds.

Key Endorsements

• Additional Insured (e.g., CG 20 10, CG 20 37): extends the insured's CGL to a landlord, lessor, or project owner required by contract; CG 20 37 adds completed-operations coverage.
• Primary and Noncontributory: makes the named insured's policy respond first, before the additional insured's own coverage.
• Amendment of Limits / Designated Premises: tailors aggregates or restricts coverage to scheduled locations.
• Pollution or Professional buy-backs: restore narrow slices of otherwise-excluded exposure.

Worked Scenario: Subcontractor Carve-Back

A general contractor's roofing subcontractor installs a roof that later leaks, damaging the building's drywall (other completed work).

• Damage to the subcontractor's roof itself: this is "your work" but performed by a sub, so the completed-operations carve-back can restore coverage.
• Damage to the drywall: covered as property damage caused by the subcontractor's work.

Without the subcontractor exception, both would be excluded as the insured's own work.

Exposures the CGL Sends Elsewhere

Several exclusions exist purely to route a loss to the correct policy, not to deny it everywhere.

• Auto, aircraft, watercraft: excluded under the CGL; covered by Business Auto or aviation/marine forms.
• Workers compensation and employer's liability: the CGL excludes injury to the insured's employees; that exposure belongs in the Workers Compensation and Employers Liability policy.
• Professional services (errors and omissions): excluded; a separate professional liability form is required for design, medical, or advisory work.

The exam rewards naming the correct policy, not merely flagging the exclusion.

Personal and Advertising Injury Coverage B

While most exclusions narrow Coverage A (bodily injury and property damage), Coverage B insures Personal and Advertising Injury — a defined list of offenses rather than physical harm.

Covered offenses include false arrest, malicious prosecution, wrongful eviction, libel, slander, and infringement of copyright in the insured's advertisement. Coverage B has its own exclusions: knowing falsehood, prior publication, and breach of contract. Modern forms also exclude intellectual-property infringement except in limited advertising contexts and may exclude certain electronic-data and access/disclosure exposures.

Pollution: A Near-Total Exclusion

The pollution exclusion is among the broadest in the CGL. It bars bodily injury and property damage arising from the discharge, dispersal, release, or escape of pollutants at premises the insured owns or operates, at waste sites, or during transport.

Narrow carve-backs exist (for example, hostile-fire heat, smoke, or fumes). Genuine environmental exposure is covered only through a separate Pollution Liability or Contractors Pollution Liability policy, never by simply endorsing the CGL.

Contractual Liability and the Insured Contract

The contractual liability exclusion bars coverage for liability the insured assumes in a contract. The critical carve-back restores coverage for liability assumed under an insured contract — a defined term that includes leases of premises, easement agreements, and the tort liability of another party assumed in a typical business contract.

So a tenant who agrees in a lease to indemnify a landlord for the tenant's negligence is generally covered, because that lease is an insured contract. A naked assumption of someone else's unrelated liability is not.

Mapping Exclusions to Solutions

When a producer reviews an account, each major CGL exclusion is a prompt to recommend a companion policy or endorsement, turning gaps into a complete program rather than leaving the insured exposed.
