Certificate of insurance checklist for California general contractors

Updated · HatBench

Short answer
  • A certificate of insurance (usually an ACORD 25) is a snapshot. It doesn't change the policy or add you to it.
  • Check the named insured matches the license, the dates cover the job, and the limits meet your contract.
  • Additional insured status and waiver of subrogation come from endorsements, so ask for the endorsement pages.
  • Confirm with the agent listed on the certificate if anything looks off, and track expiration dates.

The checklist

  1. Named insured matches the business on the CSLB license and on your subcontract.
  2. Policy dates cover the whole job, not just the start date.
  3. General liability limits meet what your contract requires (many contracts ask for $1M per occurrence / $2M aggregate; follow yours).
  4. Additional insured. If your contract requires it, ask for the actual endorsement (ongoing and completed operations). A checkbox on the certificate isn't the endorsement.
  5. Waiver of subrogation on GL and workers' comp, if your contract requires it, again by endorsement.
  6. Primary and non-contributory wording, if your contract calls for it.
  7. Workers' comp and employer's liability shown, with dates. If they're exempt, see workers' comp and subs.
  8. Auto liability if they drive company vehicles to your site, and umbrella if your contract asks for higher limits.
  9. Certificate holder is your company, with your correct name and address.
  10. Producer (the agent) is listed with contact details. Call them if anything doesn't match.

Keep it current

Certificates expire with the policy. Put every expiration date on a calendar, ask for renewals before they lapse, and keep a copy with the date you received it. Check the sub's CSLB license at the same time.

Where HatBench fits

When we introduce a sub through HatBench, you see their CSLB license status and the dates their general liability and workers' comp run through, confirmed by Insureaze. You still collect a certificate naming you before they start.
