Subcontractor Insurance Requirements: The Mistake That Could Follow You for 12 Years
Most general contractors think a signed agreement and a certificate of insurance on file mean they're covered. Here's what's usually missing from that certificate — and why the gap doesn't show up until years after the job is done.
If you're a general contractor in the Pittsburgh area, here's a scenario worth thinking through before it happens to you. You hire a sub, they hand you a certificate of insurance, it looks fine, the job gets done. Eighteen months later — sometimes years later — a defect claim shows up. You go to that certificate expecting it to cover you.
It often doesn't. Not because the sub was uninsured, but because the certificate never actually said what you assumed it said.

"Here's a scenario I see too often. A general contractor hires a sub. The sub has a certificate of insurance on file. Everything looks fine. Job wraps up. Eighteen months later, a direct claim shows up. Maybe it's a roof leak, maybe it's something structural. The GC goes to that sub's insurance expecting to see it's covered, and they're not because the certificate never actually said what everyone assumed it said.
I'm Zach Simmons with Fidelitas Insurance Partners, and I want to walk you through a handful of things that separate a certificate of insurance that actually protects you from what's just paperwork.
So why the written agreement comes first? Before we even get to the insurance piece, A handshake or a purchase order is not a substitute for a signed subcontractor's agreement. I see this all the time. "Oh, I've worked with these guys for years. I've known them forever. They do great work.
The agreement is what actually tells your carrier and a judge that the sub agreed to indemnify you, name you as additional insured, and carry their own coverage. Without it in [00:01:00] writing, your GL policy just ends up absorbing problems and claims that should have flowed downstream to your subcontractor for causing the issue in the first place.
I'm not an attorney, and this isn't legal advice. The actual agreement language needs to be written by your own attorney, and a lawyer's eyes need to be on it. What I can walk you through is the insurance side.
The COI is a gating item. No certificate on file, sub doesn't work for you. Full stop. They don't get on the job. If you let that slide just once, you've effectively decided to self-insure that sub's risk yourself. And their certificate needs to cover every line your agreement requires: general liability, auto, work comp, not just GL.
You need to have it all.
And the part everyone misses, the additional insured. There's two kinds you should be paying attention to. This is the single biggest gap I see. Additional insured sounds like one thing, and it's actually two. But most COIs only give you one of them. You have ongoing operations and completed [00:02:00] operations. So it covers you while the sub is actively on the job and covers you after the sub has already left the site.
Here's why that second one is the one that actually matters most. Nearly every construction defect claim shows up after the job is done. A COI that only shows ongoing operation status leaves you completely exposed for the claims that are actually likely to happen after the job's done.
Ask for the actual endorsement pages, not just a check mark on a certificate. Make sure the agent that they use actually put the form on the policy, and you get that form Three more things a COI needs to say. Primary non-contributory. Without this, the sub's carrier and yours can just argue over who pays first, split the bill, and erode both of your limits.
This should say that the subcontractor's policy pays first on dollar one. Waiver of subrogation. Without it, the sub's carrier can pay a claim, turn around, and sue you to get the money back. Workers' comp is the one that is most oftentimes missing this. [00:03:00] You really need to check that one.
Commercial auto. Owned, hired, and non-owned automobiles. This is a huge common gap. even their commercial policy might only cover the truck that they own and not an employee driving their own car or rented van to the job site.
You want at least a million dollars in combined single limit for any auto
Construction defect claims can show up years after a job wraps up. In Pennsylvania, the statute of repose is if the sub's policy lapses or their additional insured status expires two years after the job and the claim shows up in year six, you're on your own.
This isn't a collect a COI once and put it in a file. You need a renewal certificate every year. You need a process and you need a system. We have AI and all the tools in the world to check agreements and COIs against each other, file them away for you, go back to them if a claim arises.
There's plenty of things out there to help you. None of this is complicated once you know what you're looking for. It's five or six [00:04:00] line items on a certificate, but almost nobody checks for all of them or does the job right in general. They check a box, they move on because I get it. We're all busy, and this seems very complicated when you're looking at it from the outside in.
It's not hard. You just need to know what you're looking for. My name's Zach Simmons with Fidelitas Insurance Partners. We'd love to talk to you about your subcontractors and general contracting business to help you stay protected."
If You're Not Using Any Subcontractor Agreement at All
Everything above assumes you already have some kind of subcontractor agreement in place, even an imperfect one. If you're currently bringing subs onto jobs with nothing signed at all — no agreement, just a verbal understanding or a purchase order — the issue isn't a gap in your coverage. It's the complete absence of any risk transfer at all.
No indemnification obligation exists. If a sub causes a loss, they have no contractual duty to defend or reimburse you — the claim lands on your general liability policy in full, dollar one.
No enforceable insurance requirement. You can't require a sub to carry coverage, name you as additional insured, or maintain it for a fixed tail period, because nothing in writing establishes those terms. A verbal "yeah, I've got insurance" isn't something you can hold anyone to after a loss.
Workers' comp exposure follows you. If an uninsured sub's employee gets hurt on your job, that claim can roll up to your own workers' comp policy — one of the fastest ways to damage your experience modifier for the next three years.
Misclassification risk. Without a written agreement establishing the sub as an independent contractor, the relationship can look, on paper, like employment — opening the door to IRS or state reclassification, back payroll taxes, and retroactive workers' comp obligations.
It can affect your own coverage. Carriers increasingly ask, at application and renewal, whether subcontractor risk-transfer agreements are standard practice on your jobs. A claim that surfaces the absence of any agreement can complicate your own claim, your renewal, or both.
In plain terms: no agreement doesn't mean some risk. It means you've made yourself the insurance company for every subcontractor on every job — with none of the premium and all of the exposure.
This post walks through what a subcontractor's insurance actually needs to say to protect you, why the most common certificate is missing the piece that matters most, and how long you actually need to keep checking.
Why a Written Agreement Comes First
Before the insurance piece even matters, you need a signed agreement — not a handshake, not a purchase order. A written subcontractor agreement is what tells an insurance carrier, and a judge, that the sub agreed to indemnify you, name you as additional insured, and carry their own coverage. Without it, your own general liability policy tends to absorb problems that should have flowed downstream to the sub who actually caused them.
A note on scope: Fidelitas Insurance Partners is an insurance agency, not a law firm. The agreement language itself — indemnification clauses, lien rights, dispute resolution — needs review from your own attorney, tailored to your operations and your state. What we can walk you through is the insurance side: what the certificate needs to actually say once that agreement is in place.
Treat the Certificate as a Gating Item, Not Paperwork
No certificate of insurance on file, the sub doesn't work. If that slides "just this once," you've effectively decided to self-insure that sub's risk yourself. And the certificate needs to cover every line your agreement requires — general liability, commercial auto, and workers' comp — not just GL.
The Part Almost Every Certificate Gets Wrong
Here's the gap we see most often, and it's the one that matters most.
"Additional insured" status sounds like a single thing. It's actually two, and most certificates only show one of them:
Ongoing operations (ISO endorsement CG 20 10) — covers you while the sub is actively working on your job.
Completed operations (ISO endorsement CG 20 37) — covers you after the sub has already left the site.
Nearly every construction defect claim happens after the job is complete. A certificate that shows additional insured status without the completed-operations endorsement leaves you exposed for exactly the claims that are most likely to happen. It's worth asking for copies of the actual endorsement pages — a check-mark on a certificate isn't proof either endorsement actually exists.
Three More Lines the Certificate Needs
Primary and non-contributory. Without this language, the sub's carrier and your own carrier can end up arguing over who pays first — or splitting the bill and eroding both sets of limits. The certificate should confirm the sub's policy pays first, dollar one, before yours is ever touched.
Waiver of subrogation. Without a waiver, a sub's carrier can pay out a claim and then turn around and sue you to recover what they paid. This applies to general liability and commercial auto, and workers' comp is the line most often missing it.
Commercial auto — owned, hired, and non-owned. This is one of the most commonly overlooked requirements. A sub's personal auto policy will not respond to an accident that happens while they're working for you. Even a sub's own commercial auto policy may only cover the vehicle they own — not an employee driving their own car, or a rented van, to your jobsite. Look for at least $1 million combined single limit, covering "any auto" — not just the trucks the sub happens to own.
The Tail: Why This Isn't a One-Time Check
Construction defect claims frequently surface years after a project is finished. In Pennsylvania, the statute of repose for construction claims is 12 years (42 Pa.C.S. § 5536) — meaning a claim can legally be brought that far out from substantial completion.
That has a direct practical implication: a certificate collected once, at the start of the job, isn't enough. If a sub's policy lapses or their additional insured status expires two years after the job wraps, and a defect claim shows up in year six, there's no coverage waiting for you. Renewal certificates need to be collected annually, confirming that completed-operations coverage and your additional insured status are both still active, for the full length of that tail.
Subcontractor Insurance Requirements: What This Looks Like in Practice
None of this requires becoming an insurance expert. It comes down to a short, repeatable checklist on every subcontractor's certificate:
Signed written agreement in place before work starts
Certificate of insurance covering GL, auto, and workers' comp — collected before the sub steps on site
Additional insured status confirmed for both ongoing and completed operations (CG 20 10 and CG 20 37)
Primary and non-contributory language confirmed
Waiver of subrogation confirmed, especially on workers' comp
Commercial auto confirmed for owned, hired, and non-owned vehicles, at adequate limits
A renewal reminder set for every sub, for as long as your exposure lasts (12 years in PA)
The Bottom Line for PA General Contractors
The most expensive mistake we see isn't a sub who lacks insurance entirely — it's a sub whose certificate looked fine at a glance but was missing one of the pieces above. That gap is invisible until there's already a claim, and by then it's too late to fix.
If you'd like a second set of eyes on your current subcontractor program — what your contracts actually require versus what your subs' certificates actually show — that's a conversation we're glad to have, no obligation.
