Contractor License Requirements by State
Every U.S. state handles contractor licensing differently — some run a single statewide board, others leave it to cities and counties. Start with your state below to see exactly what’s required.
“Contractor license” means something different depending on where you’re building. A handful of states — California and Florida among them — run a centralized board that licenses general contractors statewide, with a standard exam, bond, and renewal cycle. Other states, including Texas, have no general contractor license at all at the state level, and instead regulate specific trades (electrical, plumbing, HVAC) while leaving general building work to city and county permitting offices.
That inconsistency is exactly why we built this hub state by state instead of writing one generic national guide: the honest answer to “do I need a contractor license?” is always “it depends where you’re working,” and we’d rather tell you that plainly than paper over it.

What to check before you assume you need a license
- Is there a statewide board, or is it local? States like California (CSLB) and Florida (DBPR/CILB) license general contractors directly. States like Texas push general building work down to city/county registration.
- Does your trade have its own state board regardless? Even in states without a general contractor license, electricians, plumbers, and HVAC technicians are usually licensed separately at the state level.
- What’s the project dollar threshold? Most states only require a license once a project’s labor-and-materials cost crosses a set dollar amount — below that, you may be exempt.
- Is there a bond requirement? Licensed states typically require a surety bond (often $10,000–$25,000) as a condition of licensure, separate from general liability insurance.
Do I need a contractor license to work in every state?
No. Requirements vary enormously — some states license general contractors directly through a state board, others only license specific trades, and a few (like Texas) have no statewide general contractor license at all, leaving that regulation to individual cities and counties. Check your specific state’s guide above before assuming either way.
Is a contractor license the same as a business license?
No — a contractor license certifies your trade competency and is issued by a state licensing board (or, where none exists, a local building department). A business license is a separate local/municipal requirement to legally operate any business, and most contractors need both.
What happens if I work without a required license?
Penalties vary by state but commonly include fines, being barred from filing a mechanic’s lien to collect payment, and in some states, misdemeanor or felony charges for large unlicensed jobs. States with active enforcement (California’s CSLB, for example) run sting operations specifically targeting unlicensed contractors.
