Contractor License Requirements by State: What Homeowners Need to Know Before Hiring (2026)

Every guide on contractor licensing by state is written for contractors trying to get licensed. This one is written for homeowners trying to verify one. There is a meaningful difference: knowing what your state requires tells you exactly what to demand from anyone who wants to work on your home—and what it means if they cannot produce it.

Thirty-eight states have some form of statewide contractor credential—a full license, specialty license, or registration. Twelve states regulate contractor licensing at the city or county level only, with no central state database to search. Where your state falls determines what you need to check, where you look it up, and what your legal recourse is if something goes wrong.

Why does your contractor's license status matter to you (not just to them)?

A license is not just a credential—it is a bond to a regulatory system that gives you recourse. A licensed contractor can be disciplined, suspended, or fined by a state board. An unlicensed contractor has no board to answer to, cannot pull permits in most states, and in many states cannot legally sue you for payment.

State licensing boards exist to protect consumers, not just credential contractors. When you hire a licensed contractor in California, they must carry a $25,000 surety bond—money available to cover your losses if the work is defective or abandoned. Florida's DBPR reports that unlicensed contracting is consistently one of the most common consumer complaints in the state.

The FTC received 81,925 reports of home improvement scams in 2024 alone, with a median individual loss of $1,800. The majority of those scams involve unlicensed or misrepresented contractors who have no board to answer to and no bond to claim against.

An unlicensed contractor cannot pull permits in most states, which means the work skips inspection and may have to be demolished and redone. Your homeowner's insurance may deny claims for damage caused by unlicensed work. And under California Business and Professions Code Section 7031—replicated in spirit in several other states—an unlicensed contractor cannot sue you in court to collect payment.

Which states require a general contractor license?

Twenty-nine states require a state-level general or residential contractor license. Twelve states regulate contractor licensing at the county or city level only—meaning there is no single state database to check. Nine states have no statewide general contractor license requirement, though specialty trades (electricians, plumbers, HVAC) are almost always licensed separately regardless.

States with statewide contractor licensing or registration (38): Alabama, Alaska, Arizona, Arkansas, California, Connecticut, Delaware, Florida, Georgia, Hawaii, Idaho, Iowa, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Montana, Nevada, New Hampshire, New Jersey, New Mexico, North Carolina, North Dakota, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, Tennessee, Utah, Vermont, Virginia, Washington, West Virginia. Of these, four states (Iowa, Montana, North Dakota, Vermont) require registration rather than a full contractor license.

Local-only states (12): Colorado, Illinois, Indiana, Kansas, Missouri, Nebraska, New York, Ohio, South Dakota, Texas, Wisconsin, Wyoming. In these states, there is no central state database to search. You must check with the city or county building department.

In the twelve local-only states, there is no statewide database to search. Homeowners there face the most exposure when hiring a general contractor because there is no state licensing board to file a complaint with. Specialty trade licenses for electricians, plumbers, and HVAC contractors are still required in virtually every state regardless of general contractor rules.

What does the 50-state contractor licensing comparison table show?

The table below covers all 50 states and DC from the homeowner's perspective: whether a state-level license is required, the license type, the project dollar threshold that triggers the requirement, where to verify it, and—critically—whether public disciplinary history is available in that state's database. The disciplinary history column is what no other 50-state table includes.

A few notable data points in the table: Alabama's $50,000 project threshold is among the highest in the country, meaning most standard residential remodels fall below the licensing trigger and require no state license. California licenses renew every two years—a license that was valid when you hired can expire mid-project. Florida's DBPR is one of the most comprehensive state databases, including disciplinary actions and insurance verification in a single search.

What should homeowners in local-only licensing states do?

In states like Texas, Colorado, Illinois, and New York, there is no state database to check for a general contractor license. Instead, verify the contractor's city or county registration, require proof that a local building permit has been pulled on your project, and verify any specialty trade licenses at the state level—electricians and plumbers are state-licensed in virtually every state regardless of general contractor rules.

The twelve local-only states are: Colorado, Illinois, Indiana, Kansas, Missouri, Nebraska, New York, Ohio, South Dakota, Texas, Wisconsin, and Wyoming.

Texas surprises more homeowners than any other state. There is no Texas state general contractor license, but Austin, Dallas, Houston, and San Antonio each have their own contractor registration systems. A contractor who is “registered” in Dallas has no standing in Houston without a separate registration there.

New York has a layer many homeowners miss. While there is no statewide general contractor license, New York State does require Home Improvement Contractor (HIC) registration under General Business Law §770 for contracts of $500 or more (outside of NYC). New York City has its own separate HIC license, administered by the NYC Department of Consumer and Worker Protection, required for contracts of $200 or more in the five boroughs.

In all local-only states: always require a building permit before work begins. Even where there is no contractor database to search, permits require inspection by a qualified authority and create a paper trail if something goes wrong.

What do the states with no general contractor license requirement mean for homeowners?

In states with no statewide general contractor license, there is nothing to verify at the state level. This does not mean fraud risk disappears—it means the risk is higher. Require proof of liability insurance, check the contractor's specialty trade licenses, and look up their BBB history before hiring.

States with no statewide GC license requirement include: Colorado, Illinois, Indiana, Kansas, Missouri, Nebraska, New York, Ohio, South Dakota, Texas, Wisconsin, and Wyoming. (Some of these overlap with the local-only category; the distinction is whether any statewide credential exists at all, even a registration.)

What to require when your state has no GC license:

• Certificate of general liability insurance (at minimum $1 million per occurrence)
• Proof of workers' compensation coverage or written confirmation they have no employees
• State-issued specialty trade licenses for any electrical, plumbing, or HVAC work in the project scope
• Local building permits pulled under their name before work begins
• BBB accreditation status and complaint history (more important here than in licensed states)

CheckLicensed.comcan still surface BBB history, verified reviews, and specialty trade license status in states without a statewide license—the due-diligence tools that matter most when there is no board lookup available.

What is NASCLA certification and does it mean a contractor is licensed in your state?

NASCLA is a portable contractor exam accepted by 16 states in lieu of a state-specific trade exam. Passing the NASCLA exam does not mean a contractor is licensed in your state—it means they qualified to apply for a license there. Always verify the active state license separately. NASCLA certification and a state license are two different things.

The NASCLA Accredited Examination Program is administered by the National Association of State Contractors Licensing Agencies. As of 2025, states that accept the NASCLA exam include Alabama, Arizona, Arkansas, Florida, Georgia, Louisiana, Mississippi, Nevada, North Carolina, Oregon, South Carolina, Tennessee, Utah, Virginia, West Virginia, and the U.S. Virgin Islands.

When a contractor tells you they are “NASCLA certified,” they may mean they passed the exam but have not yet obtained an active license in your specific state. The NASCLA exam is a qualification step, not the license itself. The contractor still must apply to and be approved by the state board before they hold an active license.

Most states that accept NASCLA also require a separate state-specific business and law exam. Passing NASCLA does not satisfy that requirement. A contractor who has passed NASCLA but has not yet obtained state board approval is not licensed in your state.

How do you verify a contractor's license in under 2 minutes?

Go to your state's licensing board website and search by license number or business name. Confirm the license is Active (not expired or suspended), verify the license classification matches the work being done, and look for any disciplinary history. CheckLicensed.com consolidates status, classification, disciplinary history, and reviews in a single search.

Run the three-part verification checklist on every contractor you consider:

• Status: Active? Expired means they are operating outside the rules. Suspended means there was a disciplinary action—meaningfully worse than expired.
• Classification correct? A roofing contractor's license does not authorize foundation work. A residential classification may not cover commercial projects. Verify the classification matches your specific project type.
• Disciplinary history? This is publicly available in most states with statewide licensing, but buried in separate database tabs. Most homeowners never check it. See the table above for which states publish this information.

State licensing websites have real UX problems: they go down, require exact-match searches that reject minor spelling variations, and often split license status and disciplinary history into separate lookups. If the state database is giving you trouble, CheckLicensed.comsearches license status, classification, disciplinary history, and verified reviews across all 50 states in one place—designed for homeowners, not contractors.

Mid-project re-verification is worth doing on any project that will take more than four to six weeks. California licenses renew every two years and can lapse mid-project without the homeowner knowing.

What happens if your contractor's license has expired or been suspended?

An expired or suspended license means the contractor is operating illegally. They cannot pull permits, their work may void your homeowner's insurance claim, and in most states they cannot sue you to enforce the contract for payment. If you discover this mid-project, document it in writing and contact your state's licensing board immediately.

“Suspended” and “expired” are meaningfully different statuses. An expired license may be an administrative oversight—the contractor forgot to renew and can often reinstate quickly. A suspended license means disciplinary action was taken against them by the state board. That is a pattern flag, not a paperwork error.

What an expired or suspended license means in practice:

• Insurance coverage: Many homeowner's insurance policies exclude claims for damage caused by unlicensed or improperly licensed contractors.
• Permit authority: Unlicensed contractors cannot pull building permits in most states. Work done without permits can require demolition and reinspection before a property can be sold or refinanced.
• Payment enforcement: Under California Business and Professions Code Section 7031, an unlicensed contractor cannot bring a legal action to collect payment. Several other states have similar provisions.
• Your options: Stop payment, document the license status with a screenshot of the state database showing the expired or suspended status, and file a complaint with the state licensing board.
