How to Vet a Contractor's License and Insurance

Hiring a contractor without properly verifying their license and insurance leaves you vulnerable to property damage, financial liability, and incomplete work. A verbal assurance, a slick website, or even a printed license number on a truck is not proof of compliance.

To protect your home and wallet, you must verify credentials directly with issuing agencies and insurance providers. Here is the exact process for vetting a contractor before signing a contract or handing over a deposit.

Understanding Credentials: License, Bond, and Insurance

Before you start asking for paperwork, you need to know what each document actually does and why all three are necessary.

| Document | What It Proves | Who It Protects | | :--- | :--- | :--- | | Trade License | The contractor has met minimum competency standards, passed required exams, and is legally permitted to perform specific trades in your area. | Protects you against unqualified labor and ensures compliance with local building codes. | | General Liability Insurance | The contractor has coverage for property damage or bodily injury caused by their work. | Protects your property if a worker accidentally bursts a pipe, starts a fire, or damages a neighbor's property. | | Workers' Compensation | The contractor carries medical and lost-wage coverage for their employees if an injury occurs on the job site. | Protects you from being sued or billed under your homeowner's insurance if a worker falls or gets hurt on your property. | | Surety Bond | A financial guarantee from a third party that money is available if the contractor abandons the job, fails to pay subcontractors, or breaks local laws. | Protects you financially against non-completion or unpaid subcontractor liens. |

Step 1: How to Verify a Trade License

Licensing requirements vary significantly depending on where you live. Some states issue licenses at the state level through a Department of Consumer Affairs or a Contractors State License Board. In other states, trade licenses are handled entirely at the county or municipal level.

Note: Always check with your local city or county building department to confirm which specific license class is required for your project type.

1. Request the License Details

Ask the contractor for:

2. Search the Official Database

Do not rely on a paper certificate provided by the contractor, as these can easily be edited or revoked after printing. Instead:

  1. Locate your state’s licensing board portal (or your municipal clerk's office if licensing is local).
  2. Enter the license number directly into the official lookup tool.

3. Check These Specific License Indicators

When the record appears, look for four critical pieces of information:

Step 2: How to Verify Insurance Coverage

Never accept a photocopy of an insurance card or a Certificate of Insurance (COI) passed to you by hand without independent verification. Fraudulent certificates are common in the remodeling industry.

1. Request a Certificate of Insurance (COI) Sent Directly from the Agency

Ask the contractor to have their insurance broker or agent email a Certificate of Insurance directly to you. A standard COI will list the insurance company, policy numbers, coverage limits, and effective dates for both General Liability and Workers' Compensation.

2. Require "Certificate Holder" Status

Ask the contractor's agent to list you (the homeowner) as the Certificate Holder at your specific project address on the COI. This ensures that if the contractor cancels their policy mid-project, the insurance company is obligated to notify you immediately.

3. Call the Issuing Broker

Once you receive the COI:

  1. Locate the phone number of the insurance agency/broker listed on the document (look up the number independently online to ensure it isn't a fake number).
  2. Call the agent and state: "I am verifying that policy number [X] for [Contractor Business Name] is currently active and paid in full."
  3. Verify that the coverage limits meet your project's needs (a common standard for residential remodeling is at least $1,000,000 in General Liability).

4. Verify Workers' Compensation Exemptions

In many jurisdictions, sole proprietors or single-owner LLCs without employees can legally exempt themselves from Workers' Compensation.

Step 3: Verify the Surety Bond

If your jurisdiction or project type requires a bond:

  1. Ask for the surety company’s name, bond number, and bond amount.
  2. Call the surety company to verify the bond is active and that the contractor is in good standing.
  3. Confirm that the bond covers breach of contract and failure to pay subcontractors or suppliers (which prevents mechanics' liens from being placed against your home).

Specific Questions to Ask the Contractor

Use these exact questions during your initial interview:

  1. "What is your license number, and under what trade classification is it issued?"
  2. "Will you have your insurance broker send a Certificate of Insurance listing me as a Certificate Holder directly to my email?"
  3. "Are all workers coming onto my property covered by your Workers' Compensation policy, or will you be using subcontractors?"
  4. "If you use subcontractors, do you require them to carry their own General Liability and Workers' Compensation policies, and do you verify them?"
  5. "Will you be pulling the required building permits for this project under your own license?" (Red flag: If a contractor asks you to pull an "owner-builder" permit for a project they are executing, they may be unlicensed or trying to avoid liability.)
