General Liability Exclusions Every California Contractor Should Know

General Liability insurance is essential for every California contractor — but it doesn't cover everything. Many contractors discover the gaps in their coverage only after a claim is denied. Understanding the key exclusions in your GL policy before you need it is one of the most important things you can do to protect your business.

The Most Common GL Exclusions for Contractors

1. Your Own Work ("Faulty Workmanship")

GL insurance covers damage you cause to third parties — it does not cover the cost of redoing your own defective work. If you install a roof incorrectly and it needs to be torn off and replaced, GL won't pay for the replacement roof. However, if your defective roof causes water damage to the interior of the home, GL will typically cover that resulting damage. The distinction is between the cost of correcting your work (not covered) and the consequential damage caused by your work (covered).

2. Your Own Property

GL covers damage to third-party property — not your own tools, equipment, or vehicles. If your tools are stolen from a job site, GL won't pay for them. You need Inland Marine / Tools & Equipment coverage for that. If your work truck is damaged, you need Commercial Auto coverage.

3. Employee Injuries

GL does not cover injuries to your employees — that's what Workers' Compensation is for. If an employee is injured on the job and you don't have WC, you're personally liable for their medical costs and lost wages. In California, failing to carry required WC is a criminal offense.

4. Professional Errors (Design-Build Contractors)

If you provide design services as part of your contracting work — specifying materials, designing systems, or providing engineering guidance — your GL policy may exclude claims arising from those professional services. Design-build contractors and contractors who provide specifications may need Professional Liability (Errors & Omissions) coverage in addition to GL.

5. Pollution

Standard GL policies contain a broad pollution exclusion that can affect contractors who work with chemicals, fuels, solvents, or other potentially polluting substances. Painting contractors, HVAC contractors, and anyone working with hazardous materials should ask about a Contractors Pollution Liability (CPL) endorsement or separate policy.

6. Completed Operations — Time Limits

GL covers completed operations claims — injuries or damage that arise after you finish a job — but only during the policy period. If you let your GL policy lapse and a claim arises from work you did two years ago, you may have no coverage. This is why maintaining continuous GL coverage is important even during slow periods.

7. Intentional Acts

GL does not cover damage you cause intentionally. This exclusion rarely comes into play for legitimate contractors, but it's worth knowing.

8. Contractual Liability (Some Contracts)

Standard GL policies cover contractual liability for "insured contracts" — which includes most standard construction contracts. However, if you sign a contract with unusual indemnification language (agreeing to indemnify a party for their own negligence, for example), your GL policy may not cover that expanded liability. Always have an attorney review unusual contract language before signing.
