There is no national contractor's license. Whether you need one depends entirely on your state, your trade, and the size of the job, and getting it wrong is one of the most expensive mistakes in the trades. In many states, working unlicensed where a license is required means you lose your lien rights, cannot enforce your contract, and in California the customer can legally claw back every dollar they paid you, even for perfect work. So check before you bid, not after you have done the job.
Three layers, and you might need more than one
- The general (GC) license. Some states license general contractors at the state level. Others leave GC licensing to cities and counties, so it is a local question. A few just want you registered as a business. "Do I need a GC license" genuinely has no national answer.
- The trade license. Electrical, plumbing, and HVAC almost always need their own state license, even in states where GC licensing is only local. If you do one of those trades, assume you need a trade license on top of anything else.
- The threshold. The requirement usually kicks in above a dollar amount, which varies a lot from state to state, and almost always the moment a job needs a permit.
Because all three vary, the only safe move is to check your specific state (and often your city) for the exact work you are doing.
Why this matters more than you think
Working unlicensed is not a paperwork slap on the wrist. In many states it means:
- No license, no lien. Unlicensed contractors forfeit their mechanic's lien rights entirely, so your strongest tool to get paid is gone before you start.
- You cannot enforce your contract. In a lot of states an unlicensed contractor cannot even sue to collect what they are owed.
- Clawback. In California especially, a customer can sue to recover everything they paid you, no matter how good the work was. Florida is often named alongside it and should not be: Fla. Stat. 489.128 and 713.02(7) make the contract unenforceable by you and deny you a lien, which costs you the unpaid balance rather than money already received, and neither section provides for treble damages.
- Fines and charges. Unlicensed contracting is typically a misdemeanor, and a felony for repeat offenders in some states.
Put together, doing a job unlicensed can mean you do the work, do it well, and legally get paid nothing, or worse, have to hand it all back.
The good news: reciprocity
Many states accept the NASCLA exam or have reciprocity deals with each other, so a license in one state can shortcut getting licensed in another. If you work across state lines, that is worth knowing before you sit another full set of exams.
The move
Before you bid any job, check three things for that state, and often the city:
- Does the work need a general contractor license at that dollar amount?
- Does your specific trade need its own state license?
- Does the job need a permit?
The Contractor License Checker runs this by state. Get licensed before you start work, because retroactive is not a thing here.
Common questions
Do I need a license to be a handyman?
Often no for small, unpermitted repairs, but it depends less on a dollar cap and more on the kind of work. Most handyman exemptions fall apart the moment a job needs a permit, touches electrical, plumbing, HVAC, or structure, or you bring on workers. Some states set a dollar limit, some go purely by the nature of the work, and several require you to say you are unlicensed in your ads. The exact rule is state-specific, so check the Contractor License Checker before you take the job.
Does an electrician or plumber need a separate license from a general contractor?
Almost always yes. Electrical, plumbing, and HVAC usually carry their own state trade license, even in states where general contractor licensing is only a city or county matter. If you do one of those trades, assume you need the trade license on top of any GC or business requirement. Which board issues it and what it takes vary by state, so confirm yours in Working in Your State.
Can I pull a permit without a contractor's license?
In many places the license is exactly what lets you pull the permit, so no. Building departments in a lot of jurisdictions will only issue a permit to a licensed contractor or a homeowner doing their own work. Since needing a permit is also one of the most common triggers for needing a license in the first place, the two usually go together. Check your local building department and the Contractor License Checker.
What's the difference between a contractor's license and registration?
A license usually means you had to prove competence, often an exam and experience, while registration is mostly signing up and showing insurance or a bond. Some states "register" contractors rather than "license" them, and a few just want a business registration. The label matters less than what it takes to get it and what you lose without it, both of which are set by your state. Confirm which regime your state uses before you rely on either word.
The honest bit
- Thresholds, penalties, and who does the licensing vary wildly by state and even by city, and they change. Never assume from a neighboring state. Use the Contractor License Checker and confirm against your state agency.
- This is general guidance, not legal advice. Given the size of the clawback risk in some states, this is worth getting exactly right.
