Hiring a Contractor This Spring? How to Read a Certificate of Insurance (COI) and What to Ask Before Work Starts

Spring projects have a way of moving fast. One minute you’re dreaming about a new deck or a refreshed kitchen, and the next you’re juggling bids, timelines, HOA rules, and a dozen decisions you didn’t know you had to make.

One place it’s worth slowing down—before the first day of work—is insurance paperwork. When a contractor says they’re “licensed and insured,” what does that actually mean? And when a Certificate of Insurance (COI) hits your inbox, what should you check before you file it away?

This guide is general, educational information—not legal, financial, or insurance advice. Requirements vary by state, trade, and contract, so when in doubt, ask your insurer and consider professional guidance for your specific situation.

What “licensed and insured” usually means (and what it doesn’t)

In everyday conversation, “licensed and insured” often means a contractor has a valid business or trade license (where required) and carries some form of insurance. The tricky part is that those words don’t tell you which policies are in place, whether they’re current, or whether they apply to your exact project.

Here are the common documents homeowners hear about:

• Certificate of Insurance (COI): A snapshot showing that certain policies existed on the date the certificate was issued. It’s evidence of insurance, not the insurance policy itself.
• License information: Many states and municipalities provide an official way to look up a contractor’s license status. Use your state’s licensing board (or your city/county site if applicable) rather than relying only on a business card or website claim.
• Bonding: “Bonded” can refer to different types of bonds (often related to performance or payment). Bonding is not the same thing as liability insurance, and details should be verified with the bond issuer or through official channels when relevant.

General liability vs. workers’ comp vs. bonding—plain-English definitions

Insurance terms can sound like alphabet soup, so here’s a high-level glossary you can use when reviewing a COI or asking questions.

• General liability insurance: Often intended to cover certain third-party claims for property damage or bodily injury arising from the contractor’s operations. Coverage depends on the policy and the facts of the situation.
• Workers’ compensation: Typically covers job-related injuries for employees (and sometimes other workers, depending on state rules and classifications). Whether it’s required, and for whom, is very state-specific—especially when subcontractors are involved.
• Commercial auto: If company vehicles are used for the job, this coverage may apply to certain accidents involving those vehicles. (A personal auto policy may not cover business use.)
• Professional liability: More common when design, engineering, or consulting is part of the service. It’s meant to address certain claims tied to professional services, not physical jobsite accidents.
• Bonding: A bond is generally a financial guarantee tied to performance or payment obligations. It’s a different product than insurance, and the details (and who can make a claim) depend on the bond.

If your contract, HOA, or condo association has insurance requirements, your job isn’t to “pick the perfect policy”—it’s to confirm the documentation matches those requirements and to keep records organized.

COI basics: 6 fields to check before you file it away

When you’re learning how to read a COI certificate of insurance, focus on a few practical checks. A COI is typically a standardized form, but the information entered matters.

1. Named insured: Does the legal business name match your contract, estimate, or license listing?
2. Policy types and effective dates: Are the relevant coverages listed, and are the dates current for your project timeline?
3. Limits shown: Don’t guess what’s “enough.” Confirm the limits meet whatever your contract, lender, or HOA/condo requirements specify.
4. Certificate holder: Is the certificate issued to the correct owner/entity and address as required (you, your trust/LLC, or your HOA/management company, for example)?
5. Additional insured wording: If your contract requires “additional insured,” understand that a COI alone may not create rights or change coverage. If it matters for your project, ask what endorsement applies and how it’s documented.
6. Agent/insurer contact info: Look for legitimate contact details. If anything feels off or inconsistent, it’s reasonable to confirm authenticity using contact information you obtain independently (for example, from the insurer’s official site).

For multi-month projects, it’s also smart to request updated COIs if a policy renews midstream.

A printable contractor insurance checklist for your project folder

Use this contractor insurance checklist as a copy/paste list for email—or print it and keep it with your project paperwork. The goal is clarity, not confrontation.

• “Can you send a COI directly from your agent (or have your agent email it to me)?”
• “Do you carry workers’ comp for your employees and any regular workers? If you use subcontractors, how is coverage handled?”
• “Will subcontractors be used on my job? If yes, can you provide their COIs as well?”
• “If something is accidentally damaged, what’s the process—who reports it, and to which insurer?”
• “Does our contract specify insurance requirements, and who is responsible for deductibles or uncovered items?”

Project folder system (paper + digital): contract and scope, payment schedule, COIs, license verification notes/screenshots, change orders, permits (if applicable), receipts, and a simple communication log (date, who, what was decided). This small habit can save a lot of stress later.

Common mistakes to avoid: accepting expired COIs, assuming a COI guarantees coverage for a specific loss, and skipping subcontractor documentation when subs are part of the job.

Recommended sources to consult for verification and deeper reading (and to find your state’s specific rules):

• National Association of Insurance Commissioners (NAIC) — naic.org (COI basics; consumer guidance)
• Insurance Information Institute (III) — iii.org (plain-language insurance explanations)
• Federal Trade Commission (FTC) — ftc.gov (consumer tips for hiring contractors and avoiding common pitfalls)

• California Contractors State License Board (CSLB) — cslb.ca.gov (example of an official state license lookup; use your own state’s board for your location)

Verification notes: COIs are generally evidence of insurance, not the policy itself; “additional insured” and workers’ comp rules are highly dependent on endorsements, state law, and the parties involved. When it matters for your contract, confirm details with the insurer/agent and your own advisors.
