Insurance Waivers: What a Homeowner Needs

Here’s a sentence you’ll probably hear during the planning phase of your project: “We’re fully insured — don’t worry about it.” It sounds reassuring. But it’s not a real answer. It’s a deflection.

The truth is, “fully insured” means different things to different contractors. Some mean they have the bare minimum policy required to get a business license. Others carry million-dollar liability coverage with an umbrella policy on top. And most homeowners never find out which one they’re dealing with until after something goes wrong — a worker gets hurt, a wall collapses, a leak damages the neighbor’s property.

Insurance waivers aren’t about being paranoid. They’re about understanding what happens if things go sideways, and making sure you’re not the one holding the bill. This guide covers the three documents you need to understand before any contractor starts work on your property: the certificate of insurance, the additional insured endorsement, and the waiver of subrogation.

If you’re still choosing who to hire, pair this paperwork review with the contractor hiring questions, the license and bond check, and a clear homeowner scope document before you compare bids.

The certificate of insurance: your starting point

A certificate of insurance — or COI — is a document issued by the contractor’s insurance company that summarizes their coverage. It’s not a policy. It’s a snapshot of what the policy covers, the coverage limits, the policy period, and who the named insured is.

Think of it as a cheat sheet. It tells you:

• Who is insured (the named business and individuals)
• What kind of coverage they have (general liability, workers’ comp, auto, umbrella)
• The coverage limits (how much the policy will pay per occurrence and in total)
• The policy period (when it starts and expires)
• The insurance company and policy number (so you can verify independently)

What to check on a COI

When you receive a certificate of insurance, don’t just file it away. Look at these five things:

The named insured. Does the name on the certificate match the name on your contract? If your contract says “ABC Construction LLC” but the certificate lists “ABC Construction” (no LLC), that’s a mismatch. If the contractor is operating as a sole proprietorship under their own name, the certificate should show that. A mismatch means you might not have coverage if you need to file a claim.

The general liability limit. This is the big one. For residential construction, look for at least $1 million per occurrence and $2 million aggregate. Some smaller contractors carry $500,000 in coverage. That might be enough for a minor injury but won’t touch a major claim. Higher is better, and anything under $500,000 should give you pause.

The workers’ compensation coverage. If a worker gets injured on your property and the contractor doesn’t have workers’ comp, you could be held liable for their medical bills and lost wages. The COI should show workers’ comp coverage, even if the contractor is a sole proprietor. Some sole proprietors exempt themselves from workers’ comp, which means YOU are the workers’ comp.

The policy effective dates. The certificate should show a current policy period. If the policy expires three weeks into your three-month project, the contractor will need to renew it. Add a reminder to verify the new certificate when it’s issued.

The “additional insured” box. There’s a section on most COIs labeled “Certificate Holder” or “Additional Insured.” If you asked to be listed as an additional insured (and you should), make sure your name and the project address are listed there.

How to verify a COI

A COI can be forged. It happens more often than you’d think — a contractor creates a fake certificate using a template from their insurance agent or downloads one from a website. To protect yourself, call the insurance agency listed on the certificate.

Use the phone number from the agency’s website — not the number on the certificate, since a forged certificate could include a fake phone number. Ask to confirm that policy number [POLICY NUMBER] is in force for [CONTRACTOR NAME] for the period [DATES] and includes the coverage limits shown on the certificate.

This call takes five minutes. If the agency confirms the coverage, you’re good. If they say “that policy number doesn’t match our records” or “that contractor hasn’t been insured with us for two years,” you’ve just saved yourself from a potential disaster.

Additional insured status: why it matters

Being listed as an additional insured on the contractor’s liability policy means you’re covered by their insurance if a claim arises from their work on your project. It’s an extra layer of protection that prevents the insurance company from denying your claim because you’re not the named policyholder.

This is different from being listed as a “certificate holder.” A certificate holder just receives a copy of the certificate. They have no coverage rights. An additional insured has actual coverage under the policy — within certain limits.

What additional insured status covers

If you’re listed as an additional insured on your contractor’s general liability policy, the policy will typically cover:

• Property damage caused by the contractor’s work that affects your property
• Bodily injury to third parties (not the contractor’s employees — that’s workers’ comp) that occurs due to the contractor’s operations
• Completed operations — some additional insured endorsements cover claims that arise after the project is finished

The exact coverage depends on the endorsement form used. The most common is ISO form CG 20 10, which covers ongoing operations. Form CG 20 37 also covers completed operations, which is valuable because it protects you after the contractor has left the job site.

How to request additional insured status

Ask your contractor to have their insurance company add you as an additional insured for the duration of your project. Most contractors’ agents can do this with a simple endorsement. It may cost the contractor a small fee — $25 to $100 — which you can offer to pay if they push back.

The endorsement should reference your property address and the project scope. It should specify that you’re added as an additional insured “with respect to liability arising out of [Contractor]‘s ongoing operations performed for [Your Name] at [Address].” This narrows the coverage to your project, which is what you want.

What additional insured status does NOT cover

Being an additional insured doesn’t mean the contractor’s insurance covers everything. Typical exclusions include:

• Your own negligence that causes the loss
• Damage to the contractor’s own work (that’s usually a warranty issue, not an insurance issue)
• Professional liability claims if the contractor doesn’t have professional liability coverage
• Contractual liabilities you assumed in the contract that go beyond what the policy covers

Additional insured status is a powerful protection, but it’s not a substitute for your own homeowner’s insurance. You should still maintain adequate coverage for your property during construction.

Waiver of subrogation: the hidden protection

A waiver of subrogation is the least understood but most important insurance document in construction. It prevents the contractor’s insurance company from suing you to recover money they paid out on a claim.

Here’s how it works. Say a worker is injured on your property because of a condition in your home — a rotted floorboard that collapses. The worker’s compensation insurance pays their medical bills. Then the workers’ comp insurance company says, “Actually, the homeowner is responsible for that rotted floorboard” — and they sue you to recover the money they paid.

A waiver of subrogation blocks that. It says: the insurance company can’t step into the contractor’s shoes and come after you. They paid the claim. The case is closed.

When to request a waiver of subrogation

You should request a waiver of subrogation on every residential construction project where the contractor carries workers’ compensation insurance. It’s most important for projects where there’s any risk of a workplace injury — which is essentially all construction projects.

Some contractors include a waiver of subrogation automatically in their contracts. Others will add it if you ask. A few will refuse, saying their insurance company doesn’t allow it. This is technically true for some policies but false for most. If a contractor refuses, you can ask why, or you can decide to work with someone who offers it without being asked.

How a waiver of subrogation interacts with your homeowner’s insurance

Your homeowner’s insurance policy almost certainly includes its own waiver of subrogation provisions. But your policy protects you from your insurance company suing the contractor. The contractor’s waiver of subrogation protects you from their insurance company suing you.

These are two separate protections that address two separate risks. Having both in place means neither side’s insurance company can go after the other side after paying a claim. This is the ideal arrangement for a collaborative project.

The waiver of subrogation in your contractor agreement

The waiver of subrogation should be written into your contract. A typical clause reads something like:

“The Contractor agrees to obtain a waiver of subrogation from their workers’ compensation and general liability insurers, waiving all rights of recovery against the Homeowner for claims paid under those policies arising out of work performed under this contract.”

If your contractor’s contract doesn’t include this language, ask them to add it. Most will, especially if you frame it as a protection for both of you — which it is. For a broader pre-signing pass, use the contract language checklist before work starts. Don’t confuse insurance waivers with lien waivers; they protect against different risks.

What happens when coverage is missing

It’s easy to treat insurance documentation as a checkbox exercise — get the COI, file it, move on. But the consequences of missing or inadequate coverage are real and expensive.

Scenario one: an injured worker

A roofer falls from a ladder on your property. He’s not employed by the GC — he works for a subcontractor who doesn’t have workers’ comp insurance. The subcontractor has no assets. The worker’s medical bills total $80,000.

Without workers’ comp coverage from the sub, the injured worker can sue you as the property owner. Your homeowner’s insurance may cover some of this, but it depends on your policy and whether your carrier considers construction work an excluded activity. Many homeowner’s policies exclude claims arising from “business pursuits” on the property, which can include construction.

You’re looking at a legal battle that could cost you your savings — or your home.

Scenario two: damage to a neighbor’s property

Your contractor’s excavation work causes a retaining wall to collapse onto your neighbor’s property, damaging their fence and patio. Without liability coverage, the neighbor’s insurance company pays the claim — then subrogates against you. You’re now responsible for the damage because the contractor’s negligence happened on your property.

With proper coverage — general liability insurance from the contractor, you listed as an additional insured — the contractor’s insurance pays the claim. Your neighbor gets their fence repaired, and you’re not out of pocket. Without it, you’re paying for a fence and patio on someone else’s house.

Scenario three: unfinished work

This is the most common scenario, and the one where insurance provides the least protection. A contractor takes your deposit or progress payments and disappears. You’ve lost $30,000.

If the contractor has general liability insurance, that policy typically doesn’t cover theft or breach of contract. Your additional insured status doesn’t help. The waiver of subrogation is irrelevant. Your only recourse is the contractor’s bond (if they have one), a lawsuit (if they have assets), or a criminal complaint (if they took your money with no intention of working).

This is why insurance verification is part of your planning process — but not the whole process. You also need a solid contract, a payment schedule tied to completed work, and a GC who can show you a track record of finishing projects. If the numbers look unusually low, compare the insurance paperwork against the lowest-bid warning signs and the broader contractor pricing breakdown.

How to request all three documents

Here’s a simple workflow for getting the insurance documentation you need during the planning phase of your project.

Step one: ask for the COI. Before you sign a contract, request a certificate of insurance. Tell the contractor: “I need to verify coverage with your insurance company before we start.”

Step two: verify the COI. Call the insurance agency using the number on their website. Confirm the policy is active and the coverage limits match the certificate.

Step three: request additional insured status. Ask the contractor to add you as an additional insured on their general liability policy. If they ask why, explain: “It protects both of us by making sure your coverage applies to claims related to my project.”

Step four: request a waiver of subrogation. Ask the contractor to include a waiver of subrogation in the contract for both workers’ comp and general liability. Explain: “This prevents either of our insurance companies from suing the other party after a claim.”

Step five: get updated documentation. When the endorsements are added, request an updated COI showing your name and project address as an additional insured. Store all documents in your project file.

What if the contractor pushes back?

Some contractors will resist these requests. They’ll say “nobody asks for that” or “my insurance doesn’t do that” or “you’re being paranoid.” Here’s how to respond:

“I understand this is an extra step. I’m not questioning your professionalism. I’m making sure that if something unexpected happens, we’re both protected and the project can move forward without a dispute over who pays.”

If they still refuse after that conversation, consider whether their resistance is a sign of how they’ll handle other issues during the project. A contractor who values a smooth planning process will understand that insurance verification is a standard part of professional residential construction. Keep the final paperwork with your project decision records and check it again before final payment.

Quick Answers

Q: Can I use my homeowner’s insurance instead of the contractor’s insurance?

No. Your homeowner’s insurance is designed for your personal liability and property losses, not for construction risks. Most policies exclude or limit coverage for construction activities. You need the contractor to carry their own liability and workers’ compensation coverage. Your homeowner’s policy is a backstop, not a primary coverage source for construction work.

Q: How often should I request updated certificates during the project?

Request an updated COI at each major milestone — start of work, rough-in, and final completion. Also request one if the contract changes significantly or if the project extends beyond the original policy expiration date. Each updated certificate confirms that coverage is still in force.

Q: Does being listed as an additional insured cost extra?

It usually costs the contractor a small fee — typically $25 to $100 per policy endorsement. Some contractors’ insurance policies include a certain number of additional insured endorsements at no cost. If the contractor pushes back on the cost, offer to cover the fee. It’s a small price for the protection it provides.

Q: What if the contractor is a sole proprietor with no employees?

Sole proprietors in some states can exempt themselves from workers’ compensation insurance. This means if they get injured on your property, you could be liable. Ask the contractor to sign a waiver or acknowledgment that they are not covered by workers’ comp and agree not to hold you responsible for injuries. Some states have a specific form for this. If they can’t provide one, consider whether you want to accept that risk.

Q: What does “umbrella policy” mean in a contractor’s insurance?

An umbrella policy provides additional liability coverage above the limits of the contractor’s general liability, auto, and employer’s liability policies. If a contractor has a $1 million general liability policy and a $1 million umbrella, they have $2 million in total liability coverage. Umbrella policies are common on larger contractors but rare on small ones. If a contractor has an umbrella policy, that’s a positive sign about their overall risk management.
