Do general contractors need to be licensed in every state?

No — licensing requirements vary significantly. California, Florida, Nevada, and Arizona have strict statewide licensing requirements. Texas, New York, and some other states regulate contractors primarily at the county or city level rather than statewide. Always check both state and local requirements.

How do I verify a contractor's license is valid?

Visit your state's contractor licensing board website. California has the CSLB license lookup at cslb.ca.gov, Florida uses the DBPR at myfloridalicense.com, and most other states have similar online portals. Enter the contractor's name or license number to verify status, expiration, and any disciplinary history.

What is the difference between a Class A and Class B contractor license?

In states that use this classification (Virginia, Nevada, and others), Class A (or Unlimited) licenses authorize work on any project with no dollar-value cap. Class B licenses cap project size (e.g., under $120,000 per project or $750,000 annually in Virginia). Class C covers smaller specialty work only.

Can a contractor work in my state with an out-of-state license?

Not automatically. Some states have reciprocity agreements (e.g., Louisiana and Mississippi recognize each other's licenses), but most require a separate in-state license. Contractors who moved from another state must apply for licensure in the new state. Always verify the license is issued by your state.

Contractor License Requirements by State: What You Need to Know in 2026

April 25, 2026

Why Licensing Rules Are So Inconsistent

Contractor licensing in the United States is regulated at the state level, and each state has made different policy choices about who needs a license, what testing is required, and how much bond and insurance is necessary. This creates a patchwork of requirements that confuses both contractors and homeowners alike.

States With Strict Statewide Licensing

These states require all general contractors to hold a state-issued license regardless of project size or location within the state:

California: Contractors State License Board (CSLB). Class B General Building Contractor license required for most remodel work. Requires 4 years of journey-level experience, passing trade and law exams, and a $25,000 surety bond. License lookup: cslb.ca.gov
Florida: State Certified or State Registered license through the DBPR. Certified licenses work statewide; Registered licenses are county-specific. Requires financial statements, insurance, and passing the contractor exam. myfloridalicense.com
Nevada: Nevada State Contractors Board. Class A (unlimited), Class B ($700,000 project limit), or Class C (specialty). nvcontractorsboard.com
Arizona: Arizona Registrar of Contractors (ROC). Multiple license classifications for general contracting and specialty trades. roc.az.gov
Louisiana: Louisiana State Licensing Board for Contractors (LSLBC) for commercial work; residential work regulated separately.

States With Local or Partial Licensing

Several major states leave licensing primarily to local jurisdictions:

Texas: No statewide general contractor license. However, Dallas, Houston, Austin, and San Antonio all have city-level registration requirements. Specialty trades (plumbing, electrical, HVAC) are state-licensed.
New York: No statewide GC license. New York City requires a Home Improvement Contractor license from the NYC Department of Consumer and Worker Protection. Other municipalities have their own requirements.
Colorado: No statewide GC license. Electrical and plumbing are state-licensed; general contracting is regulated locally. Denver, Boulder, and Colorado Springs each have registration programs.
Illinois: No statewide residential contractor license. Chicago requires a city license; other municipalities vary widely.

License Classifications Explained

States that tier licenses typically use one of two systems:

Class A / B / C: Used in Virginia, Nevada, and others. Class A = unlimited dollar value, Class B = project cap (e.g., $120K per project in Virginia), Class C = small jobs only (e.g., under $10,000 in Virginia).
Certified vs. Registered: Florida's model. Certified = pass the state exam, valid statewide. Registered = meet local requirements only, valid in specific counties.
General vs. Specialty: Most states separately license general contractors and specialty trades (plumbing, electrical, HVAC). A GC license does not give you the right to do electrical work — your GC must use a licensed electrician.

How to Verify a License Before Hiring

Always verify directly through the state board — never trust a license number the contractor writes on their estimate without checking it:

Get the contractor's full legal name, business name, and license number.
Visit your state licensing board's website and use the license lookup tool.
Confirm: license is active, not expired, not suspended, and covers the type of work you need.
Check for any disciplinary actions, complaints, or citations on file.
Verify the bond amount meets state minimums and that workers' comp is on file.
