Same-Day Certificates of Insurance and Additional Insured Endorsements for Contractors

Quick answer: A certificate of insurance shows a general contractor or owner what your policy covers. An additional insured endorsement is what actually extends your coverage to them. When your policy already includes the wording a contract asks for, we work to issue certificates the same business day you send a complete request. When it does not, we work with the carrier to add the endorsement and tell you up front how long that will take.

A missing or wrong certificate can stall a job or hold up a payment. Lions & Coventry Insurance Services places contractor insurance nationwide, is licensed in all 50 states (CA Lic. #0G22084) and has served contractors since 2009. We handle certificate requests for the policies we place, and we read the contract's insurance requirements before we issue anything, so the certificate matches what your policy actually provides.

Certificate of insurance vs. additional insured endorsement

Certificate of insurance (COI). Usually an ACORD 25 form. It summarizes your policies, limits and dates for the certificate holder. It is information only: it does not amend your policy, and it cannot grant coverage the policy does not include.
Additional insured (AI) endorsement. A change to your general liability policy that extends coverage to another party, usually the general contractor, project owner or property manager, for claims arising out of your work. This is what the contract is really asking for.
Blanket vs. scheduled. A blanket AI endorsement covers anyone you have agreed in a written contract to add, which makes certificates faster. A scheduled endorsement names each additional insured, so every new name needs a policy change first.

Endorsements contracts commonly ask for

The exact form numbers depend on your carrier, and many carriers use their own versions. These are the requests we see most on contractor agreements:

Ongoing operations AI, often written on ISO form CG 20 10 or an equivalent, which covers the additional insured while your work is in progress.
Completed operations AI, often CG 20 37 or an equivalent, which covers the additional insured after your work is finished. Owners and general contractors frequently require both.
Primary and noncontributory wording, so your policy responds first for the additional insured.
Waiver of subrogation on general liability, workers' compensation and sometimes commercial auto, so your insurer gives up the right to recover from the other party after it pays a claim.
Per-project aggregate, which applies your general liability aggregate limit separately to each project.
Notice of cancellation to the certificate holder, which needs an endorsement on the policy rather than a line typed on the certificate.

How to get a certificate the same day

Send the contract's insurance section. The exhibit or insurance requirements page tells us exactly what the holder expects.
Include the holder details. The exact legal name and mailing address of the certificate holder and every party to be named as additional insured.
Name the project. The project name or address, especially if the contract asks for per-project wording.
Tell us your deadline. If a payment or start date depends on the certificate, say so, and we will tell you right away whether your policy already supports the request.

If the contract asks for something your policy does not include, such as higher limits, a specific form edition or completed operations coverage for a longer period, we will explain the gap and ask the carrier to add the endorsement. That step depends on the carrier, so it is not always same-day.

Common reasons certificates get rejected

The holder name does not match the contract exactly.
The contract requires an endorsement, but the certificate only mentions it without the endorsement on the policy.
Limits on the certificate are lower than the contract requires, and there is no umbrella to make up the difference.
The policy period ends before the job does, and the holder wants a renewal certificate.
The workers' compensation section is missing or shows an exemption the general contractor will not accept.

For worked examples, see the contractors COI and additional insured checklist (California example) and contractor certificates, additional insured and class codes. The same principles apply wherever you work.

Certificates and additional insured FAQ

Can I get a certificate of insurance the same day?

Often, yes. When your policy already includes the coverage and endorsements the contract asks for, such as blanket additional insured wording, we work to issue the certificate the same business day you send a complete request. If the contract needs an endorsement your policy does not have yet, the carrier has to approve and issue it first, and that can take longer.

What is the difference between a certificate of insurance and an additional insured endorsement?

A certificate of insurance, usually an ACORD 25, is a summary of your coverage on the date it is issued. It does not change your policy or give anyone rights under it. An additional insured endorsement is part of the policy itself, and it is what actually extends coverage to the general contractor, owner or other party named in your contract.

What does primary and noncontributory mean?

It means your policy responds first for the additional insured, and it does not ask the additional insured's own insurance to share the loss. Contracts often require it alongside additional insured status. Your policy needs an endorsement that provides it; typing the words on a certificate is not enough.

What information do you need to issue a certificate?

Send the certificate holder's exact legal name and mailing address, the project name or address, the coverages and limits the contract requires, and the insurance section or exhibit from the contract. If they ask for additional insured, primary and noncontributory, waiver of subrogation or notice of cancellation, include that exact wording so we can check it against your policy.

Do you issue certificates for contractors outside California?

Yes. Lions & Coventry is licensed in all 50 states and places contractor insurance nationwide. Certificate requests work the same way wherever the project is: send the contract requirements and the holder details, and we check them against your policy before we issue anything.

Brokerage guidance, not legal advice. Coverage depends on the policy form, underwriting and carrier availability, and licensing and insurance rules vary by state.
