A waiver of subrogation is an endorsement in which your insurer gives up its right to come after a specific other party — usually the general contractor or property owner — to recover money after it pays a claim. General contractors demand it so that after any covered loss on the job, nobody's insurance company turns around and sues everyone else on the project. It's cheap or free on general liability, carries a small surcharge on workers' comp, and it's required in almost every commercial construction contract you'll sign. The one rule that matters: get it in place before work starts, because a waiver added after a loss often doesn't count.
When your insurance company pays a claim that someone else actually caused, it doesn't just eat the cost. It has the right to step into your shoes and go recover that money from the party at fault. That right is called subrogation. If a crane operator from another sub damages your equipment and your carrier pays to fix it, your carrier can then sue that operator's company to get its payout back. That's subrogation working normally — and it's a good thing, because it keeps costs with the party that caused the harm.
A waiver of subrogation switches that right off against one specific party. You (through an endorsement on your policy) tell your insurer: even if you pay a claim, you agree not to chase this particular party to recover it. The injured or damaged party still gets paid; your insurer simply agrees not to seek reimbursement from the named entity.
Construction is a crowd. On any given job you've got an owner, a general contractor, a dozen subs, and their insurers, all working feet apart. When something goes wrong — a worker is hurt, a finished floor is ruined, a fire starts — one insurer pays. Without waivers, that insurer then sues every other party on the site to recover, and suddenly the whole project team is in litigation with each other over a loss that insurance already covered.
Mutual waivers of subrogation stop that. They keep the loss with the carrier that paid it and keep the project team out of court against one another. That's why they appear in AIA contract forms and virtually every commercial construction agreement, almost always bundled with two companion requirements:
Together these three push the project's risk down onto the subcontractor's policy. If you're the sub, you're the one providing all three. Understanding the difference between them matters — see our companion explainer on additional insured vs. certificate of insurance, which trips up contractors constantly.
These get confused because they show up in the same contract clause, but they do opposite jobs:
| Additional Insured | Waiver of Subrogation | |
|---|---|---|
| What it does | Adds the other party ONTO your policy | Gives up your insurer's right to recover FROM the other party |
| Direction of protection | Your policy defends & pays for them | Your insurer won't sue them after paying you |
| Who benefits | The GC/owner gets coverage | The GC/owner avoids a recovery lawsuit |
| Typical lines | GL, auto, umbrella | GL, workers' comp, auto, umbrella |
One adds a protected party; the other removes a recovery right. A contract that asks for "additional insured, primary and non-contributory, and waiver of subrogation" is asking for three separate endorsements — and your certificate of insurance needs to reflect all of them.
This is the part contractors most often misunderstand, so it's worth being exact. A waiver of subrogation on your workers' compensation policy does not reduce or change what an injured employee receives. Your hurt worker still gets full comp benefits — medical and wage — exactly as they always would.
What the waiver changes is what happens after those benefits are paid. Normally, if the general contractor's negligence contributed to your employee's injury, your comp carrier could sue the GC to recover what it paid out. With a waiver of subrogation on your comp policy, your carrier agrees not to pursue that recovery against the named GC. The employee is unaffected; the party giving something up is your insurance company.
There are two ways to carry a waiver:
If you work for more than one general contractor — which is most subs — a blanket waiver on both GL and workers' comp is almost always the right call. It lets you satisfy a new contract's requirement the same day instead of waiting days for the carrier to issue a scheduled endorsement while the GC holds up your start.
Small, but not always zero:
| Coverage | Typical 2026 cost | Notes |
|---|---|---|
| General liability | Often free or a small flat fee | Many carriers add a blanket GL waiver at no charge |
| Workers' compensation | ~1%–5% of comp premium (blanket) | Real surcharge; per-project waivers can be cheaper |
| Commercial auto / umbrella | Usually small or included | Varies by carrier; confirm it's endorsed |
These are illustrative ranges, not filed rates — the exact charge depends on your carrier, state, and premium size. But the theme holds: the cost of a waiver is trivial next to the value of the contract it lets you sign. It's a line item, not a deal-breaker.
A waiver that doesn't actually attach is worse than none, because you signed a contract believing you were covered. The usual failure modes:
Bettr Coverage is an independent commercial insurance agency serving Georgia and the wider Southeast. Contract insurance requirements — additional insured, primary and non-contributory, and waivers of subrogation across GL, workers' comp, auto, and umbrella — are exactly the kind of thing a real agency sets up correctly in advance so you're never scrambling when a GC hands you a contract and wants a certificate tomorrow. We carry your endorsements as blanket where it makes sense, read the insurance clause of your contracts so you don't sign a requirement you can't meet, and shop your whole program across multiple carriers rather than defending one company's rate. One agency, one relationship, the full stack of construction endorsements handled before the job starts.
Bettr Coverage sets up your GL, workers' comp, auto, and umbrella endorsements — additional insured, primary/non-contributory, and waivers — so you can sign the contract and start the job without a coverage scramble.
Get a free coverage reviewAn endorsement where your insurer gives up its right to recover money from a named party after paying a claim. On a job, the GC or owner requires it so no insurer sues the project team after a covered loss.
To prevent finger-pointing lawsuits. Without mutual waivers, the carrier that pays a loss can sue everyone else on the project to recover, dragging the whole team into litigation over an insured claim.
Often free or a small fee on GL; roughly 1%–5% of premium on workers' comp for a blanket waiver. Small relative to the contract it lets you sign, but a real item on comp.
No. The employee gets full benefits either way. The waiver only stops your carrier from suing the GC/owner to recover what it paid.
Blanket if you work for multiple GCs, so you can meet any contract instantly. Specific names one party or project and is slightly cheaper per instance.
Most often by timing — adding it after a loss when the contract required it before. Also by naming the wrong entity, putting it on the wrong policy, or a state that restricts comp waivers.
