Contractor License Requirements by State: 2026 Complete Guide
Whether you need a contractor license, and what kind, depends entirely on where you work. Some states require a license for nearly every type of construction activity. Others have no state-level licensing at all and leave it to cities and counties. Getting this wrong can result in fines, project shutdowns, and legal liability.
This guide covers licensing requirements in all 50 states, with detailed breakdowns for the most active construction markets.
Contractor Licensing
Do You Need a Contractor License?
The short answer: in most states, yes, but the specifics vary dramatically.
Here is a quick way to determine your requirements:
- Check your state's requirements using the tables below
- Check your city and county, since many local jurisdictions require licenses even when the state does not
- Determine which license type applies to your trade and project size
- Verify threshold amounts, since some states only require licenses above a certain dollar amount

States with Minimal or No State-Level Licensing

States with No State-Level General Contractor License
- Colorado
- Delaware
- Illinois
- Indiana
- Iowa
- Kansas
- Kentucky
- Maine
- Missouri
- New Hampshire
- New York (except NYC)
- Ohio
- Oklahoma
- South Dakota

Critical note: In all of these states, cities and counties may require their own licenses, permits, and registrations. For example:
- New York City requires a license from the NYC Department of Buildings for general contractors, plumbers, electricians, and other trades
- Chicago requires contractor registration and trade-specific licenses
- Denver requires a contractor license for all construction work
- Columbus, OH requires contractor registration
Always check with your local building department before starting work.
Texas: A Special Case
Texas does not require a state-level general contractor license. However, several specialty trades require state licensing:

| Plumber | TSBPE | Apprentice, journeyman, tradesman, and master levels; exams required |

Detailed Requirements for Major States

Virginia uses a tiered system based on project value:
| Class | Project Value | Bond Requirement |
|---|---|---|
| Class A | $120,000 or more | $50,000 |
| Class B | $10,000 to $119,999 | $25,000 |
| Class C | Up to $10,000 | None |
All classes require passing the Virginia contractor exam. Class A and B applicants must also meet financial requirements and demonstrate experience.

North Carolina requires licensing for general contractors on projects valued at $30,000 or more.
License classifications:
- Building Contractor (Limited, Intermediate, Unlimited)
- Highway Contractor
- Public Utilities Contractor
- Specialty Contractor (Limited, Intermediate, Unlimited)

Key licenses:
- Construction Supervisor License (CSL): Required for anyone overseeing residential construction or renovation. Must pass a proctored exam.

- Utility Contractor: Gas, water, sewer, and related infrastructure
- Conditioned Air Contractor: HVAC installation and repair

Commercial general contractors in Georgia are not required to hold a state license but may need local licenses in most jurisdictions.
What Happens If You Work Without a License
The consequences of working without a required license are serious and vary by state:
Financial Penalties
| State | Penalty for Unlicensed Work |
|---|---|
| California | Up to $15,000 fine (first offense), criminal misdemeanor |
| Florida | Up to $10,000 fine per offense, criminal charges possible |
| Arizona | Up to $1,000 per day of violation, plus project shutdown |
| Nevada | Up to $50,000 in fines, criminal penalties |
| North Carolina | Up to $500 per day, injunction |
Other Consequences
- Loss of lien rights: In most states, unlicensed contractors cannot file a mechanics lien. This means if a customer does not pay, you may have no legal recourse.
- Unenforceable contracts: Courts in many states (including California and Florida) have ruled that contracts with unlicensed contractors are void and unenforceable. You cannot sue to collect payment.
- Criminal charges: Many states classify unlicensed contracting as a misdemeanor. Repeat offenses can be charged as felonies.
- Insurance issues: Your general liability and workers' comp insurance may not cover claims arising from unlicensed work.
- Customer complaints: State licensing boards actively investigate complaints about unlicensed contractors, often triggered by dissatisfied customers.
Bond and Insurance Requirements
Most states that require contractor licenses also mandate some combination of bonds and insurance.
Surety Bonds
A surety bond protects customers if you fail to complete a project or violate state contracting regulations. Bond amounts vary by state and license type.
| State | Typical Bond Amount |
|---|---|
| California | $25,000 |
| Florida | Varies by net worth ($25,000 typical) |
| Arizona | $2,500 - $100,000 |
| Nevada | $1,000 - $500,000 |
| Oregon | $10,000 - $75,000 |
| Virginia | $25,000 - $50,000 |
| Washington | $6,000 - $12,000 |
Insurance Requirements
| Coverage Type | Typical Requirement |
|---|---|
| General Liability | $500,000 to $1,000,000 per occurrence (varies by state) |
| Workers' Compensation | Required in nearly every state if you have employees |
| Auto Insurance | Required for business vehicles in all states |
| Professional Liability | Not typically required by licensing boards but recommended |
How to Get Licensed: General Process
While every state's process is different, here is the general path:
Step 1: Verify Requirements
Contact your state's licensing board (see the table above) or visit their website. Determine which license classification applies to your trade and project type.
Step 2: Meet Experience Requirements
Most states require 2 to 4 years of verified experience in the trade. Some accept a combination of education and experience. You will typically need to document your experience through employer verification forms or affidavits.
Step 3: Pass Required Exams
Most states require one or two exams:
- Trade exam: Tests your knowledge of construction methods, materials, codes, and safety
- Business and law exam: Tests your knowledge of contract law, lien law, insurance, and business management
Study materials are available from your state licensing board and from third-party exam prep companies like PSI, Prometric, and state-specific prep courses.
Step 4: Obtain Bond and Insurance
Purchase your surety bond and insurance coverage before applying. Your licensing board will require proof of both.
Step 5: Submit Your Application
Complete your state's application, which will typically require:
- Completed application form
- Experience documentation
- Exam scores
- Bond certificate
- Insurance certificates
- Financial statement (some states)
- Fingerprints and background check (some states)
- Application fee ($100 to $500 in most states)
Step 6: Maintain Your License
After issuance, maintain your license by:
- Renewing on time (annually or biennially in most states)
- Completing any required continuing education
- Keeping your bond and insurance current
- Updating the board on any changes to your business
Beyond Your Contractor License: Other Essential Documents
A contractor license is just one piece of the paperwork you need to run a legitimate contracting business. In addition to your license, you will need:
- Business registration with your state's Secretary of State
- Federal EIN from the IRS
- Sales tax permit or resale certificate for purchasing materials tax-free in states that allow it
- City or county business license in your operating area
- Trade-specific permits pulled for each project
In addition to your contractor license, you will need a resale certificate to purchase materials tax-free for qualifying projects. This is separate from your contractor license and is issued by your state's tax authority, not your licensing board.
