COI

How to Get a Certificate of Insurance in California

A Certificate of Insurance (COI) is the standard document that proves your business carries active insurance coverage. In California, it is the single most-requested piece of paperwork in the contractor and service business world. General contractors, property managers, commercial developers, government agencies, and even residential clients routinely ask for a COI before allowing you to start work.

What a Certificate of Insurance Contains

A standard COI (ACORD 25 form) summarizes your insurance coverage in a one-page document. It includes:

The COI is evidence of coverage — it is not the policy itself and does not modify coverage terms. It is a summary for informational purposes.

Certificate Holder vs. Additional Insured

This is one of the most common sources of confusion for California contractors. The two terms sound similar but have very different legal effects:

Most California general contractors and commercial clients require additional insured status, not just certificate holder listing. Adding an additional insured requires an endorsement to the policy, which your agent or carrier must process. This can typically be done same-day.

Waiver of Subrogation

A waiver of subrogation is a contract provision that prevents your insurance carrier from pursuing reimbursement from the other party after paying a claim. Many California construction contracts and commercial leases require a waiver of subrogation on your GL policy. This endorsement must be added to the policy and listed on the COI — it cannot be granted verbally or through the contract alone.

How to Get a Same-Day COI in California

If you have an active General Liability policy, your agent can issue a COI the same day you request it. The process is straightforward:

  1. Contact your agent with the certificate holder's name, address, and any specific endorsement requirements (additional insured, waiver of subrogation, per-project limits).
  2. Your agent generates the COI through the carrier's system or agency management software.
  3. The COI is emailed directly to you, your client, or both.

What to Do When a Client Asks for Higher Limits

Sometimes a California client requires higher limits than your current policy provides — for example, $2 million when your policy carries $1 million. You have several options: increase your policy limits, purchase an umbrella policy to extend coverage, or negotiate the requirement with the client. A licensed agent can help you evaluate which approach makes the most sense for your business and the project.
