Does Commercial Umbrella Cover General Liability?
Often—a commercial umbrella can add limits above a scheduled general-liability policy, but the underlying limits must meet the umbrella’s requirements and the claim must fit both policies’ terms.
Triple-I describes umbrella limits as sitting over scheduled underlying policies, typically including general liability, and California’s regulator says umbrellas cover amounts above basic liability limits. These descriptions do not establish that every CGL claim is covered by every umbrella.
The underlying CGL policy must usually meet the umbrella’s required limits and be maintained as specified. The umbrella may exclude a type of claim covered by the CGL, narrow its coverage, or require a self-insured retention where no underlying policy applies. Aggregate exhaustion can also affect how limits attach.
Check the umbrella schedule for the exact CGL policy and limits, then compare exclusions, definitions, occurrence and aggregate provisions, defense terms, and renewal conditions. Ask how a claim excluded by the CGL would be treated under the umbrella.
