The bottom line
15 states have no state-level contractor license at all, so the check you need depends entirely on where the job is. California has the strictest state licensing regime in our data, and among the 115 trade-state combinations with a specified surety bond, the typical requirement runs about $17,539 (from $10,000 to $500,000). Never assume, always look up your state and trade before you sign.
According to state licensing boards, NCSL, and NASCLA, PlainHireCheck compiles more than 1,020 trade-by-state licensing requirements, last refreshed in June 2026; see our methodology for the full source list.

Hiring Tips from Consumer Advocates
Protect yourself with these essential steps before and during any contractor project.
Always Verify a License Before Hiring
Before signing any contract, verify the contractor's license on your state licensing board website. License lookup tools are free and take less than a minute. Never accept a license number without verifying it yourself.
Get At Least Three Written Bids
Always get at least three written bids for any project over $1,000. Bids should be itemized and specify materials, labor, timeline, and payment schedule. Beware of bids significantly lower than others.
Check Insurance Separately from Licensing
A contractor can be licensed but uninsured. Ask for a Certificate of Insurance (COI) naming you as additional insured. Verify it is current by calling the insurer. Both general liability and workers' compensation are important.
Never Pay More Than 10-30% Upfront
Be cautious of contractors demanding large upfront payments. A typical schedule: 10-30% down, incremental payments as work progresses, and 5-10% retained until completion and inspection.
Get Everything in Writing Including Change Orders
A detailed written contract protects you. It should include scope of work, materials, timeline, payment schedule, and warranty terms. Any changes must also be in writing as change orders.
Check the Contractor Complaint History
Most state licensing boards show complaint history and disciplinary actions. Ongoing unresolved complaints are a red flag. Also check the BBB and Google Reviews.

Frequently Asked Questions
What is the difference between a licensed and unlicensed contractor?
A licensed contractor has met state-specific requirements including education, experience, exams, and background checks. They carry required insurance and bonds. An unlicensed contractor has met none of these requirements. Hiring an unlicensed contractor may void your homeowner's insurance, expose you to liability if a worker is injured, and leave you with no legal recourse for defective work.
Does a license guarantee quality work?
No. A license means the contractor met minimum standards at the time of licensing. Always check reviews, ask for references, and see past project photos. However, a licensed contractor provides legal protections that an unlicensed contractor does not.
What is a contractor bond and why does it matter?
A contractor bond (surety bond) is a three-party agreement between the contractor, a bonding company, and you. If the contractor fails to complete a job or causes damage, you can make a claim against the bond. Bonds typically have limits ($5K-$100K) — they are a baseline protection, not comprehensive coverage.
What is contractor liability insurance?
General liability insurance covers property damage and bodily injury caused by the contractor. Always ask for a Certificate of Insurance showing at least $500,000-$1,000,000 in general liability coverage.
What is workers compensation and why do I care?
Workers' compensation covers contractors and their employees if injured on your property. Without it, an injured worker could potentially sue you as the property owner. Always verify workers' comp coverage before work begins.
Can I hire an unlicensed contractor to save money?
The risks are significant: work may not pass inspection, homeowner's insurance may deny claims, you could be liable for injuries, and you have limited legal recourse. Where contractor licensing is required by law, hiring unlicensed is also illegal.
