11.3 Key CGL Exclusions and Endorsements

Why the exclusions matter

The insuring agreement of CG 00 01 is broad, so the exclusions do most of the real work of defining the policy. Examiners love to present a claim that sounds covered and ask which exclusion bars it. Coverage A (Bodily Injury & Property Damage) carries roughly fourteen lettered exclusions (a through n). Learn the high-frequency ones below and the endorsements that buy some of them back.

High-frequency Coverage A exclusions

The business-risk exclusions (j, k, l, m)

The most heavily tested cluster. The CGL is not a performance bond or warranty: it will not pay to repair or replace the insured's own defective product or faulty workmanship. If a contractor installs a roof badly, exclusion (l) 'Damage to Your Work' bars the cost to redo the roof. But if the bad roof leaks and ruins the building owner's inventory inside, that resulting property damage to other property is covered — the exclusion stops at the insured's own work. Distinguishing the cost of the defective work (excluded) from resulting damage to other property (covered) is a classic exam scenario.

Pollution and the absolute exclusion

Exclusion (f) is the absolute pollution exclusion. It bars bodily injury or property damage arising from the actual, alleged, or threatened discharge, dispersal, seepage, migration, release, or escape of pollutants — plus any cleanup costs demanded by a government authority. There are narrow exceptions (e.g., certain hostile-fire heat/smoke, building-heating fumes). Environmental exposures are instead written on separate Pollution Legal Liability / Contractors Pollution policies. On the exam, a contaminated-soil or fume-inhalation scenario almost always points to the pollution exclusion.

Key conditions and endorsements

Separation of insureds: Coverage applies separately to each insured as though each held its own policy, so one insured's excluded conduct (e.g., an intentional act) does not automatically void coverage for an innocent co-insured. Other insurance settles as primary, excess, or contributing (equal shares or by limits).

Common endorsements that modify the form:

• Additional Insured (e.g., CG 20 10 ongoing operations / CG 20 37 completed operations): extends the named insured's coverage to a third party such as a project owner, common in construction contracts.
• Primary and Noncontributory wording: forces the named insured's policy to pay first without seeking contribution from the additional insured's own CGL.
• Waiver of Transfer of Rights of Recovery (CG 24 04): waives subrogation against a designated party.
• Aggregate Limits Per Project / Per Location (CG 25 03 / CG 25 04): gives each project or location its own General Aggregate, preventing one large claim from eroding the cap for all jobs.

The Insured-Contract Carve-Back

The contractual-liability exclusion (b) bars liability the insured assumes by agreement, but it immediately gives much of it back through the insured contract definition. An insured contract includes leases of premises, sidetrack agreements, easement or license agreements, obligations to indemnify a municipality, elevator-maintenance agreements, and - most importantly for construction - that part of any contract under which the insured assumes the tort liability of another to pay for bodily injury or property damage.

This is the mechanism by which a subcontractor's CGL can answer for a hold-harmless clause favoring the general contractor. When a question describes a hold-harmless or indemnity agreement, test it against the insured-contract definition before concluding the exclusion applies.

Additional Insureds and the Construction Chain

The additional-insured endorsements are among the most commercially important provisions. CG 20 10 adds a party (such as a project owner or general contractor) for the named insured's ongoing operations, while CG 20 37 adds them for completed operations - both are usually required by construction contracts, and missing one leaves a gap after the job is finished.

Paired with primary and noncontributory wording and a waiver of subrogation (CG 24 04), these endorsements shift the risk of the subcontractor's work onto the subcontractor's policy and protect the upstream party. The exam tests the combination: additional-insured status plus primary-and-noncontributory plus waiver of subrogation is the standard "risk-transfer package" in contracting.

Reading an Exclusion Question

When a scenario sounds covered, ask three questions: Does an exclusion bar it? If so, does a carve-back (insured contract, reasonable-force self-defense, hostile-fire pollution) restore it? And does the loss involve the insured's own work/product (excluded business risk) versus resulting damage to other property (covered)? Working through exclusion, then carve-back, then business-risk analysis in that order produces the right answer on the exclusion questions that dominate the CGL portion of the exam.
