Contractor License Requirements by State

March 21, 2026 · Daniel Amar·Last updated: March 21, 2026

Not every state licenses contractors the same way

In California, working without a contractor license on a job over $500 is a misdemeanor with fines up to $15,000. In Texas, there's no state-level general contractor license at all. Same country, completely different rules.

Contractor licensing is one of the least consistent regulatory areas in the country. Some states have a centralized state licensing board with strict exams and bonding. Others leave it entirely to cities and counties.

California (CSLB)

California has one of the most structured contractor licensing systems in the country, run by the Contractors State License Board (CSLB).

  • Who needs a license: Anyone performing work valued at $500 or more (including labor and materials)
  • License types: Class A (General Engineering), Class B (General Building), and 42 specialty classifications (C-licenses). Plumbing is C-36, Electrical is C-10, HVAC is C-20.
  • Requirements: 4 years of journey-level experience, pass a trade exam and a law/business exam, $25,000 contractor's bond, workers comp insurance (if you have employees).
  • Fees: $450 application + $150 per exam. License $200 initial, $450 renewal every 2 years.
  • Timeline: 12 to 18 weeks from application to license.

California is strict about enforcement. Operating without a CSLB license on jobs over $500 is a misdemeanor with fines up to $15,000 for a first offense.

Texas: no state-level general contractor license

Texas doesn't have a state-level licensing requirement for general contractors. But specialty trades ARE licensed at the state level: electricians (TDLR), plumbers (TSBPE), and HVAC technicians (TDLR) all need state licenses. Many Texas cities also require contractors to register locally.

The lack of state licensing doesn't mean less regulation. It means the regulation is scattered across multiple agencies and jurisdictions. See our original contractor license guide for a broader overview.

Florida (DBPR and CILB)

Florida has a two-tier licensing system: state-certified (valid statewide, issued by the CILB under DBPR) and county-registered (valid only in the issuing county). Exam fees are about $300. Contracting without a license on jobs over $1,000 is a third-degree felony. Continuing education: 14 hours every 2 years for renewal.

New York: varies by city and county

New York doesn't have a state-level contractor license. NYC requires a Home Improvement Contractor license ($200/2 years plus surety bond). Requirements vary wildly by jurisdiction. A license from NYC doesn't cover work in Westchester, and vice versa.

The cost of getting it wrong

Working without a required contractor license isn't a gray area. California: misdemeanor, up to $15,000 fine. Florida: third-degree felony. NYC: $500 to $5,000 per violation. Beyond the legal penalties, an unlicensed contractor can't enforce a contract in court (in California). Read more about what happens when your contractor license expires.
