How to Verify Contractor Insurance Before Work Starts

How to Verify Contractor Insurance Before Work Starts

Get a current Certificate of Insurance (COI) from your contractor and confirm it directly with the insurer before anyone sets foot on your property. That single step prevents most of the financial exposure homeowners face when uninsured contractors cause damage or injury. To verify contractor insurance completely, you need three things: the COI, a confirmed active license from your state's contractor licensing board, and proof of workers' compensation if the crew has employees. If you'd rather hand that process to a professional, 30apropertycollective manages contractor verification as part of its estate management services along Florida's Emerald Coast.

Quick verification checklist (do this before work begins):

  1. Request the COI directly from the contractor's insurance agent, not the contractor.
  2. Look up the contractor's license on your state licensing board's online portal.
  3. Call the insurer using a phone number from the insurer's public website to confirm the policy is active.
  4. Ask for an Additional Insured endorsement naming you and your property address.
  5. Confirm workers' comp coverage if the contractor has employees.

Key Takeaways

Confirming contractor insurance before work starts requires a COI, insurer confirmation, a license check, workers' comp verification, and an Additional Insured endorsement — all completed before the first payment.

Step-by-step: how to verify license, COI, workers' comp, and subcontractor coverage

Follow these four steps before the first payment clears or the first day on site. If the project runs longer than a month, set a calendar reminder to re-check.

Step 1: Verify the contractor's license

Go to your state's contractor licensing board website and run the license number the contractor gave you. Check: license status (active vs. expired or suspended), license classification (does it match the work being done?), expiration date, bond status, and any complaint or disciplinary history. Most state portals take under five minutes.

Step 2: Authenticate the COI

Many verification failures come from accepting screenshots or old COIs. Call the insurer using a phone number you find on the insurer's public website, not the number printed on the COI. Confirm the policy number, named insured, coverage limits, and effective/expiration dates. Ask whether the homeowner has been added as Additional Insured.

Step 3: Confirm workers' compensation

Workers' compensation is required in most states once a contractor has employees, and if a contractor has employees but no WC, you may become the default responsible party for any on-site injury claim. State-run tools like the Electronic Workers Compensation Coverage Verification System (EWCCV) let you confirm whether a contractor carried a WC policy on a specific date. Many states have their own equivalent portal.

Step 4: Collect subcontractor COIs

Verification stepWhat to checkTiming
License lookupActive status, classification, bond, complaintsBefore hiring
COI authenticationPolicy #, named insured, limits, datesBefore first payment
Workers' comp confirmationActive account, covers all crewBefore work starts
Subcontractor COIsEach sub named or covered under GC policyBefore subs arrive on site

What should you do if the contractor is uninsured or the COI looks fake?

Stop work immediately. Do not sign off on any final payment or authorize the next phase until the coverage question is resolved. Then work through this list:

  • Call the insurer or agent directly using contact details you find independently, not from the contractor.
  • Ask the contractor to provide the agent's name and phone number and confirm the policy yourself.
  • Request proof that all subcontractors on site are covered.
  • Document every communication in writing, including emails, texts, and call logs with dates and times.
  • Notify your homeowner's insurance carrier that work was in progress and coverage may be in question.
  • If you suspect the COI was altered or fabricated, contact your state's insurance department or contractor licensing board to report it.
  • Withhold final payment until a valid COI and Additional Insured endorsement arrive from the agent.

Do not let the contractor pressure you into resuming work before coverage is confirmed. A contractor who resists verification is a contractor who has something to hide.


Red flags to watch for and questions to ask

Most insurance fraud in the contractor space is not sophisticated. It shows up as small inconsistencies that are easy to catch if you know what to look for.

Red flagWhat it likely means
Refuses to provide a COINo coverage, or coverage that won't hold up to scrutiny
COI older than 30 daysPolicy may have lapsed since it was issued
Business name mismatchCOI may belong to a different entity
"No employees" but multiple workers on siteMisclassified workers; WC gap
Screenshot instead of agent-sent COIPossible alteration
No Additional Insured endorsement offeredHomeowner has no direct claim against the policy

Questions to ask the contractor:

  • "Can your agent email the COI directly to me?"
  • "Who is the carrier and can I call them to confirm policy number X?"
  • "Are all subcontractors covered under your policy, or will you provide their COIs separately?"
  • "Does your GL include products and completed operations coverage?"

Questions to ask the agent:

  • "Is this policy currently active and paid to date?"
  • "Can you add my name and property address as Additional Insured and send the endorsement?"
  • "Will you notify me 30 days before any cancellation?"

Pro Tip: Watch for behavioral signals: a contractor who pressures you to skip verification, asks you to pull permits in your own name, or gets evasive when you ask for the agent's contact information is showing you exactly how the project will go.


Contract clauses that tie payment to valid insurance

The contract is where your verification work becomes enforceable. Add these clauses before signing anything, and require the agent-sent COI and endorsements before the first payment.

  • COI required before start: — "Contractor shall provide a current Certificate of Insurance from its agent to Owner before commencing work. Work should not begin until Owner has received and confirmed the COI."

Insert your name, property address, and project end date where indicated. For contract management support, 30apropertycollective can help structure these requirements as part of its vendor oversight services.


How professional estate managers verify contractor insurance

Estate managers who oversee high-value properties treat contractor verification as a repeatable process, not a one-time task. The vendor and contractor oversight practices used by professional managers follow a consistent sequence.

Before any contractor is hired, the manager collects the COI, calls the insurer to confirm the policy, and logs the policy number, limits, and expiration date in a certificate file. Every sub gets the same treatment. Expiration dates go into a calendar with a 45-day advance reminder so there's time to request a renewal certificate before the old one lapses.

Mid-project re-checks happen automatically when a project spans more than 30 days. If the insurer confirms a lapse, work stops. If the contractor refuses to cooperate, the manager contacts the state licensing board and the homeowner's insurer the same day.

Pro Tip: Store your COI PDF, the Additional Insured endorsement, the insurer confirmation email, and a screenshot of the license lookup result in a single project folder. If a claim ever arises, that file is your evidence.

The verification step most homeowners skip

The part of contractor insurance verification that actually prevents losses is not the paperwork — it's the phone call. Homeowners collect the COI, glance at the dates, and assume they're covered. The COI is a summary document. It does not confirm the policy is paid, active, or that you are actually named as Additional Insured. The only way to know those things is to call the insurer yourself.

I've seen projects where the contractor handed over a COI that looked perfectly fine. The business name matched, the dates were current, the limits looked right. But when the insurer was called, the policy had lapsed two weeks earlier for non-payment. The contractor had no idea, or claimed not to. Either way, the homeowner would have been exposed.

The four-move verification routine — ask for the COI, get it from the agent, confirm subcontractor coverage, call the carrier — takes less than an hour. That hour is the difference between documented protection and an expensive assumption.
