For a lot of general contractors in New York, collecting a subcontractor’s certificate of insurance feels like closing the loop. The document gets filed, the box gets checked, and the risk feels like it’s moved on to someone else.
The reality, confirmed repeatedly in New York courts, is different. An expired certificate, a policy with thin limits, or an additional insured designation that was never actually formalized in the endorsement can leave the general contractor holding the bag — and paying out of their own policy — for an incident they thought was someone else’s problem.
A certificate of insurance is a snapshot, not a guarantee
A certificate of insurance (COI) confirms that, at the moment it was issued, the subcontractor had an active policy with certain limits. That’s all it is — a snapshot of a single moment, and the document itself says it’s issued “for informational purposes only.” The underlying policy can get cancelled weeks later for non-payment, renew at lower limits, or simply lapse midway through a long project without anyone noticing. The certificate doesn’t update itself, and too many general contractors file it away at kickoff and never look at it again.
Additional insured: being named isn’t the same as being covered
This is where most general contractors get an expensive surprise. Having your name shown up on the certificate doesn’t automatically mean the subcontractor’s policy responds for you first. Real protection requires the subcontractor to add you as an additional insured through a specific endorsement — and that endorsement needs to state the coverage is primary and non-contributory, meaning the subcontractor’s policy pays before yours ever gets touched. Without that language, you can end up paying out of your own policy for the exact risk you thought you had transferred.
A real case: when “being covered” wasn’t enough
In 2024, New York’s Appellate Division, Second Department, decided New York City Housing Authority v. Harleysville Worcester Insurance Co. — a case that lays out exactly this problem from a general contractor’s seat. A general contractor subcontracted the electrical work on a project, and the subcontract required the subcontractor to name the general contractor as an additional insured on its policy. When one of the subcontractor’s employees was injured and sued everyone involved, the general contractor did qualify as an additional insured — unlike the project owner, who was left out for lacking a direct contractual relationship with the subcontractor.
But that’s not where it ended. The court also looked at the policy language and found the subcontractor’s coverage was excess, not primary, relative to the general contractor’s own policy. In practice, that meant the general contractor had to burn through the limits of its own policy first before it could even reach the subcontractor’s coverage. So even though the general contractor technically qualified as an additional insured, the payment order ended up being exactly what requiring that insurance in the first place was supposed to prevent.
That outcome tracks a pattern set by New York’s highest court back in 2018, in Gilbane Building Co./TDX Construction Corp. v. St. Paul Fire & Marine Insurance Co., where a construction manager was left with no coverage at all for not having a direct contract with the right party. The takeaway for general contractors is straightforward: requiring the subcontract to name you as additional insured isn’t enough on its own. You need to confirm the endorsement actually says “primary and non-contributory,” or the protection you thought you negotiated may not be there when you need it.
The contract is your first line of defense
Before any policy ever comes into play, the contract already decided who’s responsible for what. Transfer of risk provisions — typically indemnification and hold-harmless language — put the obligation on the subcontractor to answer for damage caused by its work. The construction industry has a name for the strictest version of this: a “hard hammer clause” — if the subcontractor doesn’t maintain the required coverage, including primary and non-contributory language, there’s no insurance backing that risk, and the general contractor is exposed directly, on its own policy.
Why the margin for error keeps shrinking in New York
New York’s Labor Law — Sections 240 and 241 in particular — puts liability on owners and general contractors that can be triggered even when a subcontractor directly caused the accident. Layer on top of that an environment where state safety organizations documented a 48% jump in construction-related deaths in 2023, the highest in a decade, and the math is clear: a general contractor can’t afford to assume someone else’s insurance will respond when a claim comes in. That has to be confirmed in advance, not discovered after the fact.
What a general contractor should check before work begins
- Actual coverage dates, not just the issue date. A certificate that’s valid on the day you sign the contract doesn’t guarantee anything six months later, mid-project. Ask for an updated certificate at every policy renewal, not just at kickoff.
- Coverage limits relative to project size. A subcontractor carrying minimum limits on a high-value project can come up short on a real claim — and that gap lands on someone else.
- The endorsement itself, not just the certificate. Request a copy of the additional insured endorsement to confirm the language actually exists in the policy, not just on the cover sheet.
- “Primary and non-contributory” status. Confirm the endorsement explicitly states the subcontractor’s coverage pays before yours — not after.
- Ongoing verification, not a one-time check. Put a simple process in place to reconfirm the subcontractor’s coverage stays active for the life of the project, not just at signing.
Conclusion
Transferring risk to a subcontractor isn’t a box you check once at the start of a project — it’s something that needs to hold up for as long as the work continues, and New York courts have made that point more than once.
