General Liability Exclusions to Watch for on Subcontractor Policies

By SubCover HQ · Updated Nov 4, 2026 · 2 min read

A certificate of insurance tells you a policy exists, who wrote it, and the limits. It doesn't tell you what the policy excludes. Some general liability policies sold to contractors, especially low-cost ones, carry exclusions that can wipe out coverage for exactly the work you hired them to do.

Exclusions that come up most often

How to check

  1. Put a requirement in your subcontract that the sub's GL has no exclusions that apply to the work being performed.
  2. Ask the sub's agent directly whether the policy has classification limitations or residential, height, or action-over exclusions.
  3. For larger or higher-risk jobs, ask for the policy's declarations page and endorsement schedule, or the policy itself.
  4. Compare the description of operations on the certificate against the work in the contract. A mismatch is a reason to ask questions. See our description of operations guide.

Why it matters for additional insured status

If you're an additional insured on a sub's policy, the same exclusions apply to you. An endorsement naming you is only worth as much as the coverage underneath it. See CG 20 10 and CG 20 37 endorsements.

Key takeaways

A clean-looking certificate can sit on top of a policy that excludes your job. Require no applicable exclusions in writing, ask the agent about the common ones, and get the endorsement schedule on bigger jobs. SubCover HQ checks every certificate against your requirements, flags mismatches, and tracks every expiration, for $99/month.

Frequently asked questions

Does a certificate of insurance show exclusions?

No. A certificate shows policies, dates, and limits. Exclusions are in the policy and its endorsements, so you have to ask the agent or review the endorsement schedule.

What is a classification limitation endorsement?

An endorsement that limits coverage to the operations listed on the policy, so claims from other kinds of work may not be covered.

What is an action-over exclusion?

An exclusion for claims where an injured employee of a contractor sues another party, such as the general contractor or owner, who then looks to the sub's policy.
