In most US states, yes - you do need a contractor license for construction arbitrage. If you are entering the prime contract with the client, the law treats you as the contractor of record, and in the majority of states that means holding the relevant contractor license before you take the first job. About 33 states have statewide licensing requirements; the rest regulate locally or not at all. The exact class of license depends on the state and the type of work.
This is the question I get asked more than almost any other. Let me answer it properly, state by state, from experience running this model licensed across multiple markets.
Do you need a contractor license for construction arbitrage - the core rule
Construction arbitrage means you are the prime contractor. You win the job, price it, manage the subs, and keep the spread. You are not the tradesperson on the tools - but in the eyes of the client, the law and the licensing board, you are the contractor.
That is exactly why the license question matters. The requirement to hold a license attaches to who enters the prime contract, not to who physically does the work. Subcontracting everything out does not eliminate your licensing obligation - it just means someone else is physically doing the work you have contracted to deliver.
In is construction arbitrage legal I cover the full compliance picture - licensing, insurance, tax. This post goes deeper on the license question specifically, state by state.
States that require a general contractor license
Around 33 US states have statewide general contractor licensing requirements. The specifics - which exam, what fee, what experience is required - vary, but the principle is the same: you cannot enter a prime contract for construction work above the state's threshold without the license.
California - the strictest example
The Contractors State License Board (CSLB) requires a contractor license for any project where the combined cost of labor and materials is $1,000 or more, or where a building permit is required regardless of cost. That threshold was raised from $500 to $1,000 by Assembly Bill 2622, effective January 1, 2025.
For construction arbitrage - which almost always means real jobs well above $1,000 - you operate under a license. Full stop.
- Class B (General Building): the right classification for multi-trade jobs - remodels, fit-outs, and builds that involve two or more unrelated trades. Most construction arbitrage operators in California sit here.
- Class A (General Engineering): infrastructure and large engineering projects.
- Class C: specialty trades - electrical, plumbing, HVAC, and 42 other specialty classifications.
Getting the CSLB license requires passing a written exam, paying a non-refundable application fee of $450, paying an initial license fee of $200 (sole owner) or $350 (non-sole owner), posting a $25,000 contractor's bond, and demonstrating four years of journeyman-level experience in the trade or type of work.
From July 1, 2026, the minimum civil penalty for unlicensed contracting in California rises to $1,500 - and an unlicensed contractor cannot use the courts to recover payment on work performed. That is a serious exposure. Get the license.

Florida
Florida licenses contractors through the Department of Business and Professional Regulation (DBPR). The state issues two tiers:
- Certified contractor: licensed statewide, able to work anywhere in Florida.
- Registered contractor: licensed locally, limited to the municipality or county that issued the registration.
For construction arbitrage you want the certified license - it is not tied to one locality. The exam covers three parts: Business and Finance, Contract Administration, and Project Management. Florida requires documented experience (four years at the journeyman or supervisory level), financial responsibility documentation, and proof of liability insurance.
New York
New York has no single statewide GC license in the way California does. Instead, contractor licensing sits at the city and county level. New York City requires a Home Improvement Contractor license for residential work and a General Contractor registration for new buildings above three stories. Nassau, Suffolk and Westchester counties each run their own licensing systems. If you are taking prime contracts in New York, verify the local licensing requirement for exactly where the work sits.
Other common licensing states
Alabama, Arizona, Arkansas, Connecticut, Georgia, Louisiana, Maryland, Michigan, Minnesota, Mississippi, Nevada, North Carolina, Oregon, South Carolina, Tennessee, Virginia, Washington and around 15 others all have statewide GC licensing. The exam and fee structures differ but the principle is the same - hold the right license before entering the prime contract. Check the specific state licensing board for the current requirements.
States without a statewide general contractor license
Around 17 states - including Texas, Kansas, Colorado, Illinois, New Hampshire and Vermont - have no statewide general contractor license requirement for most work. Texas is the largest example: the state imposes no statewide GC license and no statewide exam. You can enter a prime contract in Texas without a state-level credential.
That does not mean no rules. In Texas:
- Austin, Dallas, Houston and San Antonio each require their own contractor registration or permit registration.
- Specialty trades are regulated statewide: electricians under TDLR, plumbers under the Texas State Board of Plumbing Examiners, HVAC under TDLR.
- Your subcontractors must hold the relevant trade licenses for regulated work, even where you as the GC do not need a state license.
The practical rule: in non-licensing states, go to the city or county where the work sits and confirm what local registration or permit requirements apply before you take the prime contract. Never assume "the state doesn't require a license" means "no rules at all."
Outside the US - the short version
The licensing question applies globally, though the structure differs:
United Kingdom: there is no contractor license in the UK in the same sense. What you must do is register with HMRC as a CIS contractor before paying your first subcontractor. CIS compliance - verifying subs, making the correct deductions, filing monthly returns - is the compliance mechanism. Skipping it triggers penalties on the full gross payment. Register at GOV.UK.
Canada: licensing sits at the provincial level, with significant variation. Quebec requires a license from the Régie du bâtiment du Québec (RBQ). Ontario requires HCRA registration for new home construction. British Columbia requires Technical Safety BC certification for specialist trade work. Check the specific province.
Australia: state and territory based. New South Wales requires a contractor licence from NSW Fair Trading for building work over $5,000 in labor and materials. Other states have their own frameworks and thresholds.
The global answer is the same as the US answer: the requirement attaches to who enters the prime contract. Check the licensing body in your jurisdiction before you take the first job.
What "license lending" means - and why it is illegal
A common shortcut I see people consider: use another licensed contractor's credential to cover their work. This is called license lending and it is illegal in every state that licenses contractors. The license holder can lose their license, face fines, and be held liable for work performed under their credential. The person using the borrowed license faces the same penalties as if they had no license at all.
The legitimate route is to become the Qualifying Individual (QI) on your own entity's license - either as a sole owner or as an officer of your LLC or corporation - by sitting the relevant exam yourself. Or, in states that allow it, hire a licensed Responsible Managing Employee (RME) or Responsible Managing Officer (RMO) who becomes the QI for your entity. The CSLB in California allows this structure explicitly; check your own state's rules.
The licensing step in the right sequence
Getting licensed is not the hard part of this business. It is a one-time setup cost. The sequence I recommend:
- Confirm which license class you need for the type of work and state where you plan to operate.
- Register your business entity first - you typically apply for the license as the entity, not as an individual.
- Sit the exam. Most state exams have a business and law section plus a trade section. Study materials are available for every major state board.
- Post the required bond and get your liability insurance in place - both are usually conditions of license issuance.
- Apply. Processing times vary from weeks to months depending on the state.
For the full setup sequence - entity, license, insurance, first clients, first subs - see how to start a construction arbitrage business.
The license is not an obstacle. It is the thing that makes the spread yours to keep legally. Get it once and run clean.

Frequently asked questions
Do you need a contractor license to do construction arbitrage?+
In most US states, yes. If you are entering the prime contract with the client, the law treats you as the contractor of record - and most states require that person to hold a contractor license for work above a value threshold. About 33 states have statewide GC licensing requirements; the remaining states regulate locally or not at all.
Which states don't require a general contractor license?+
Texas, Kansas, Colorado and a handful of others have no statewide general contractor license. That does not mean no rules - cities like Austin, Dallas and Houston each impose their own registration requirements. Always check the specific municipality where the work sits, not just the state.
What license class do I need for construction arbitrage?+
If you are running multi-trade jobs - a remodel or fit-out that touches several trades at once - you typically need a Class B (General Building) contractor license in states like California. Single-trade jobs fall under the relevant specialty license. Check the licensing board in your state for the exact classification.
What happens if you do construction arbitrage without a license?+
You face civil and criminal penalties. In California, contracting without a license is illegal and carries a minimum civil penalty of $1,500 from July 2026, and an unlicensed contractor cannot sue to recover payment. Florida and most other licensing states have similar exposure. The risk is real and not worth it.
Do I need a license if I only subcontract and never touch the work?+
Yes - in licensing states the requirement attaches to who enters the prime contract, not who physically does the work. The fact that you subcontract everything out does not remove the licensing obligation. You are the contractor of record regardless of who is on site.
Can I use someone else's license for construction arbitrage?+
No. Operating under another person's license - known as 'license lending' - is illegal in every state that licences contractors and carries its own penalties. The license holder must be the Qualifying Individual for your entity, either as an officer or owner.
