What Happens if a Subcontractor Does Not Have Insurance?

Last updated July 2026.

If a subcontractor does not have insurance, the liability for anything they cause moves to you. Their claims hit your general liability policy and your loss history, your insurer can reclassify their labor as your payroll at audit and bill you premium on it, and your contract with the owner is usually in breach the moment an uninsured sub sets foot on the site. The exposure is not theoretical and it is rarely capped.

General contractors and property owners tend to treat a missing certificate as a paperwork problem. It is a financial one. The three ways it costs money are a claim you end up paying, an insurance audit that treats the sub as your employee, and a contract that lets the owner withhold payment or terminate you. Any of the three can dwarf the value of the work the sub was doing.

What happens if a subcontractor does not have insurance and causes damage?

The injured party sues everyone in the chain, and the party with coverage pays. That is you. Your general liability policy responds to the claim, your deductible or self-insured retention applies, and the loss goes onto your five-year loss runs where it raises your premium at every renewal afterward.

Your subcontract almost certainly contains an indemnity clause requiring the sub to hold you harmless. That clause is still enforceable against an uninsured subcontractor, but enforcing it means suing a small business that has no insurance and probably no assets. A judgment against a company that dissolves is a piece of paper. The insurance requirement exists precisely because the indemnity is only as collectible as the balance sheet behind it, and how courts have actually treated these clauses varies enough by state that you should not assume the language alone protects you.

The workers compensation audit problem

This is the cost that surprises people, because it arrives with no accident at all.

At your annual workers compensation and general liability audit, your carrier asks for certificates of insurance for every subcontractor you paid during the policy period. For any subcontractor you cannot produce a valid certificate for, the auditor treats the amount you paid them as your own payroll and charges premium on it at the applicable class code.

The arithmetic is unpleasant. A roofing class code can run north of 20 dollars per 100 dollars of payroll in some states. Pay 300,000 dollars to a roofing sub whose certificate you cannot find, and the audit bill for that one vendor can exceed 60,000 dollars. There is no claim, no injury and no dispute about fault. You simply could not produce the paperwork.

Two details make this worse than it sounds. The auditor usually wants a certificate covering the dates the work was performed, not just any certificate. And in many states, if the sub carried general liability but no workers compensation, you get charged for the workers compensation exposure anyway.

What if the subcontractor had insurance but it lapsed mid-project?

Functionally the same as never having it, for the period it was lapsed. Coverage is judged by the date of the occurrence, not the date you collected the certificate. A sub whose policy expired in March and who caused a loss in April is uninsured for that loss even though your file holds a certificate that looked perfect when you accepted it in January.

This is the single most common failure mode in vendor compliance and it has nothing to do with negligence at intake. The certificate was fine. Nobody was watching the expiration date. What happens when a vendor's insurance expires covers the mechanics in detail, and it is the reason expiration monitoring matters more than intake screening.

A related trap: a policy can be cancelled mid-term without expiring. The certificate still shows a valid date range, but the coverage is gone. The ACORD 25 cancellation notice language has been watered down over the years and generally obliges the insurer to notify only in accordance with policy provisions, which usually means the certificate holder is not notified at all.

Are you legally required to make subcontractors carry insurance?

Not by federal law in most cases, but the requirement usually reaches you through three other routes:

• Your own contract. Prime contracts and leases almost always require that all lower-tier parties carry specified coverage. Letting an uninsured sub work is a breach of your agreement with the owner, independent of whether anything goes wrong.
• State licensing rules. Many states require licensed contractors to carry general liability, workers compensation or a bond, and some make the hiring contractor responsible for verifying it.
• Statutory employer laws. In a number of states, if your subcontractor has no workers compensation coverage, their injured employee's claim falls to your policy by operation of law. You become the employer for compensation purposes whether you agreed to or not.

Public work adds another layer, with its own insurance and bonding schedules written into the solicitation. Insurance required for government contracts covers those requirements.

What are your options when a subcontractor cannot get coverage?

Sometimes the sub is not stalling, they genuinely cannot place the risk or cannot afford it. There are legitimate ways to proceed and one way that is not.

If you go the wrap-up route, be precise about what the wrap covers and what it does not, because off-wrap exposures such as auto liability and tools coverage usually stay with the sub. Wrap-up insurance, OCIP vs CCIP covers the difference.

Can you withhold payment from an uninsured subcontractor?

Usually yes, if your subcontract says so, and this is the enforcement mechanism that actually works. Standard subcontract language conditions payment on the sub maintaining the required insurance and providing evidence of it. A subcontractor who ignores five emails asking for a renewed certificate will respond within an hour to a held payment application.

Two cautions. Prompt payment statutes in many states limit how and why you can withhold, so the contractual basis needs to be clear and the withholding needs to be documented in writing at the time. And mechanics lien rights generally survive a payment dispute, so withholding does not make the obligation disappear, it just creates leverage.

The practical structure is to make compliance status a gate rather than a report: no certificate, no site badge, no payment release. That only functions if the person approving payments can see compliance status without asking anyone, which is what subcontractor compliance software is for.

How to prevent this instead of reacting to it

Every case above traces back to the same two failures: a certificate that was never verified against the actual requirement, or an expiration nobody was watching. Both are solvable before the fact.

1. Verify at intake, not just collect. Check limits against your subcontract minimums, confirm the required endorsements are present rather than just referenced, and confirm the policy dates cover the scheduled work. Subcontractor certificate of insurance requirements sets out the baseline.
2. Watch every expiration date. Reminders at 60, 30 and 15 days give you three chances to get a renewal before there is a gap, which is roughly how long it takes a sub's agent to reissue a certificate.
3. Gate site access and payment on status. Compliance data that does not stop anything gets ignored by everyone.
4. Keep dated evidence. When the audit comes, you need to show what was on file and when, not just what is on file today.

The short version

An uninsured subcontractor is not a paperwork gap, it is an open position on your own balance sheet. The claim lands on your policy, the audit bills you for their payroll, and your prime contract is in breach while they are on site. Verify coverage before work starts, monitor expirations continuously, and make payment conditional on compliance. Those three habits eliminate almost the entire exposure, and none of them require a lawyer.
