You just won the job. You're ready to get to work — and then you hit the insurance section of the contract. Additional insured. Primary and non-contributory. Waiver of subrogation. Minimum limits of liability. Suddenly you're staring at a full page of terms that read like another language.
Here's the part most contractors don't realize: that page isn’t just a formality. If your coverage doesn't match what the contract requires — exactly — you can lose the job before you get started, or worse fail to get paid after you finish. Potentially the most damaging, if you sign promising coverage you don't actually carry, a claim can land on you personally.
This guide walks through every requirement you're likely to see, in plain English, so you can meet each one with confidence.
Why contracts require insurance in the first place
When a general contractor, developer, or property owner hires you, they're taking on risk. The work you are doing on their project, with your crew and equipment. The insurance section is how they push that risk back onto your coverage and confirm you carry enough to stand behind the job. Every line in that section exists to protect them if something goes wrong. Your job is to match it.
The contractor insurance requirements checklist
1. Certificate of Insurance (COI)
The certificate of insurance is the one-page proof that you carry the coverage the contract requires. Almost every contract asks for it before you can start work or receive payment. But remember: a COI is only proof. The real work is making sure the policies behind it actually contain the terms below.
2. Commercial General Liability — at the required limits
Nearly every contract requires commercial general liability (CGL), and it will specify minimum limits — commonly around $1,000,000 per occurrence and $2,000,000 aggregate, though larger projects often demand more. If your limits are lower than the contract requires, you don't meet it. The number matters as much as the coverage itself.
3. Additional Insured (ongoing and completed operations)
An additional insured endorsement extends your liability coverage to the general contractor or property owner for claims arising out of your work. Watch the wording carefully: strong contracts require additional insured status for both ongoing operations (while the work is happening) and completed operations (after the job is done). Often, they will also require a copy of the endorsement made to your policy verifying this coverage. The endorsement for the ongoing operations is the CG 2010 and the endorsement for completed operations is CG 2037. If your policy only covers one, you have a gap the contract didn't allow for.
One important distinction: being listed as a “certificate holder” is not the same as being an additional insured. A certificate holder only receives proof of coverage — they get no protection under your policy.
4. Primary and Non-Contributory
This phrase means your policy pays first (primary), and the other party's policy does not have to contribute (non-contributory). Without it, your insurer could try to force theirs to split a claim. Contracts include this language specifically to prevent that.
5. Waiver of Subrogation
Normally, if your insurer pays a claim, it can try to recover that money from whoever was at fault — a process called subrogation. A waiver of subrogation means your insurer gives up that right against the party you're contracting with. It has to be added to your policy by endorsement; it is not automatic.
6. Workers' Compensation and Employers Liability
If you have employees, expect the contract to require workers' compensation, often with specified employers’ liability limits. In most states this coverage is legally required regardless — but the contract will want documented proof.
7. Commercial Auto Liability
If you or your crew drive to jobsites or haul materials, the contract will likely require commercial auto liability with its own minimum limits — and sometimes additional insured and waiver of subrogation on the auto policy as well.
8. Umbrella / Excess Liability
On larger projects, the required limits may exceed what your base policies carry. If a contract requires $5,000,000 and your general liability limit is $1,000,000, an umbrella (or excess liability) policy stacks on top to reach the number the contract demands.
What happens if your coverage doesn't match
Two things may happen, and both are expensive. On the front end, if your certificate doesn't reflect the required coverage, many general contractors simply won't let you on site or won't release payment. On the back end, if you signed promising coverage you don't actually have and a claim occurs, you can be personally responsible for the gap — and in breach of the contract you signed. Getting this right isn't just paperwork; it's protection.
How to make sure you comply — before you sign
Read the insurance section in full before signing anything. Then get the actual requirements in front of your agent — not just a summary. A good independent agent will compare the contract to your policies line by line, advise you on any endorsements you're missing (additional insured for both operations types, primary and non-contributory, waiver of subrogation), discuss adjusting limits or quote adding an umbrella where needed, and issue a certificate that says exactly what the contract wants to see.
Frequently asked questions
What does “additional insured” mean in a contract?
It means the other party — usually the general contractor or property owner — is added to your liability policy by endorsement, so your coverage protects them for claims arising out of your work.
Is a certificate holder the same as an additional insured?
No. A certificate holder only receives proof that your coverage exists. An additional insured actually receives coverage under your policy. A contract that requires additional insured status is not satisfied by simply listing someone as a certificate holder.
What general liability limits do contracts usually require?
Common minimums are around $1,000,000 per occurrence and $2,000,000 aggregate, but larger or higher-risk projects frequently require more — often satisfied with an umbrella policy.
What does “primary and non-contributory” mean?
It means your policy pays first on a covered claim, and the other party's policy is not required to contribute.
What is a waiver of subrogation?
It's an endorsement in which your insurer agrees not to pursue reimbursement from the party you're contracting with after paying a claim. It must be added to your policy; it isn't included automatically.
