What Is a Contractor License?
By BRIX Editorial Team · Updated
A contractor license is a state or local credential that allows a business to bid and perform construction work above a set dollar amount or in a regulated trade. Licensing boards usually require experience, an exam, a surety bond and proof of insurance. Working unlicensed can void your contract, block lien rights and bring fines.
Key takeaways
- Rules are set state by state, and sometimes city by city. There is no national contractor license.
- Most states license by dollar threshold, by trade, or both: California at $1,000, Florida at $2,500, North Carolina at $40,000 for general contractors.
- Electrical, plumbing and HVAC are licensed in most states even where general building work is not.
- A license usually comes with a bond and insurance requirement, and lapses if those lapse.
- Unlicensed work can cost you more than a fine: in Florida the contract is unenforceable by the contractor.
When do you need a contractor license?
You need a contractor license when your state, county or city says the work you're doing requires one, which usually depends on three things: the dollar value of the job, the trade, and whether the work needs a permit. Many states exempt small jobs below a threshold, but almost all of them license electrical and plumbing work regardless of size.
Thresholds are measured on the whole job, labor and materials together. Splitting one project into small invoices to stay under the line doesn't work: California's licensing board treats it as one project, and Florida's exemption excludes work divided up "for the purpose of evading" the law.
Contractor license requirements in six states
| State | Who issues it | When a license is required | Bond and insurance |
|---|---|---|---|
| California | Contractors State License Board (CSLB) | Any job of $1,000 or more (labor and materials). Below $1,000 you still need a license if the work requires a permit or you employ anyone on the job (AB 2622, effective Jan. 1, 2025). | $25,000 contractor license bond (since Jan. 1, 2023). Workers' comp if you have employees, and for some classes even without. |
| Florida | Construction Industry Licensing Board (DBPR) | No one may contract without being certified or registered in the proper classification. Casual or minor work under $2,500 total is exempt, unless it's part of a larger job or you advertise as a contractor. | Contractors need public liability and property damage insurance (§ 489.115(5)) and workers' comp or an exemption (§ 489.114); local governments can deny permits without proof. |
| Texas | TDLR (electrical, A/C and refrigeration); State Board of Plumbing Examiners (plumbing); cities for building work | A state license is required to perform electrical work (Occ. Code § 1305.151) or air conditioning and refrigeration contracting (§ 1302.251), regardless of job size. General building and remodeling are regulated mainly at the city level through registration and permits. | Varies by trade and city; many cities require proof of insurance to register or pull permits. |
| North Carolina | Licensing Board for General Contractors | A general contractor must be licensed if the total project cost is $40,000 or more. | Set by license classification and limitation; check the board. |
| Washington | Department of Labor & Industries (contractor registration) | Contractors register with L&I. Registration is built on a bond and insurance rather than a trade exam; trade credentials are separate. | Continuous surety bond of $30,000 (general) or $15,000 (specialty), plus general liability of $250,000 combined single limit (or $200,000 public liability and $50,000 property damage). |
| Oregon | Construction Contractors Board (CCB) | Contractors license with the CCB under a residential or commercial endorsement that matches the work they do. | Residential general contractor: $25,000 bond and $500,000 per occurrence liability insurance, with products and completed operations coverage. |
Each of our state guides covers that state's licensing board alongside sales tax and estimated tax rules, for example California, Florida and Texas.
How do you get a contractor license?
- 1
Pick the right classification.
General building, residential, specialty trade, or a limited-dollar license. Bidding outside your classification can be treated like working unlicensed.
- 2
Document your experience.
Many boards want years of journey-level or supervisory experience, verified by employers, clients or a licensed contractor.
- 3
Pass the exams.
Usually a trade exam plus a business and law exam covering lien law, contracts, payroll and safety.
- 4
Get bonded and insured.
Buy the license bond the board requires (see surety bond) and the required general liability insurance and workers' compensation.
- 5
Register the business.
Form your entity, get an EIN, and register for state tax accounts. Business names on the license, bond and insurance usually have to match exactly.
- 6
Track renewals.
Licenses expire, often every one to two years, and some require continuing education. A lapsed bond or insurance policy can suspend the license automatically.
What happens if you work without a license?
Working without a required license can cost you the job's revenue, not just a fine. Penalties vary by state, but the common consequences are these:
- You may not be able to collect. Florida makes contracts entered into by an unlicensed contractor unenforceable by that contractor (Fla. Stat. § 489.128).
- You can lose lien rights. If you can't enforce the contract, a mechanic's lien usually goes with it.
- Fines and criminal charges. Many states treat unlicensed contracting as a misdemeanor, with higher penalties for repeat offenses or disaster areas.
- Insurance problems. Some policies and most commercial contracts require a valid license.
Contractor licensing by trade
| Trade | How it's usually licensed | Notes |
|---|---|---|
| Electrical | State license in most states, often with journeyman and master levels | Texas, for example, requires a TDLR license to perform electrical work |
| Plumbing | State or local license nearly everywhere | Gas piping and backflow testing often need extra endorsements |
| HVAC | State license in many states, sometimes under a mechanical classification | Texas licenses A/C and refrigeration contracting statewide |
| Roofing | Specialty license in some states; general license or registration elsewhere | Some states add workers' comp rules specific to roofers |
| General contractor and remodeling | State license by threshold, or local registration | North Carolina licenses GCs on jobs of $40,000 or more |
| Landscaping, cleaning, pest control | Landscaping often unlicensed below thresholds; pest control licensed through agriculture departments | Irrigation and pesticide work are commonly licensed |
Contractor license vs. registration vs. business license
A contractor license proves competence in a trade, usually through exams and experience. A contractor registration, like Washington's, proves you're bonded, insured and on file, with no trade exam. A general business license from your city or county is a tax and zoning registration that every business needs, licensed or not. Most contractors need at least two of the three.
Common licensing mistakes
- Bidding outside your classification. A specialty license doesn't cover the general work around it.
- Letting the bond or insurance lapse. Many boards suspend the license automatically when the surety or insurer notifies them.
- Mismatched names. The license, bond and insurance certificate should show the same legal business name.
- Forgetting local licenses. A state license doesn't always replace a city or county registration.
- Missing renewal and continuing-education dates. Working on an expired license is working unlicensed.
Frequently asked questions
How much work can you do without a contractor license?
It depends on the state. California allows minor work under $1,000 only if no permit is needed and you have no employees on the job; Florida exempts minor work under $2,500; North Carolina requires general contractors to be licensed at $40,000. Trade work like electrical is usually licensed at any size.
Does Texas require a general contractor license?
Texas licenses specific trades statewide, including electrical and air conditioning and refrigeration through TDLR and plumbing through the plumbing board. General building and remodeling are regulated mainly by cities, which may require registration, insurance and permits. Check with the city where the job is.
Can I use someone else's contractor license?
Generally not, outside the formal process of having a licensed qualifier for your business. Renting or lending a license is prohibited in many states and can lead to discipline for the license holder and penalties for the unlicensed contractor.
Do I need a license to be a subcontractor?
Usually yes, if the work you do requires a license. Most state rules apply to anyone who contracts to do the work, not just the general contractor. A licensed GC generally can't hire an unlicensed sub for licensed trade work.
Is a contractor license the same as being bonded and insured?
No. A license is permission to do the work. A license bond protects consumers and workers if you don't follow the licensing law, and insurance pays for injuries and property damage. Many states require all three to keep a license active.
How long does it take to get a contractor license?
Plan on weeks to months. Boards have to verify experience, schedule exams, process the bond and insurance, and run background checks where required. Registration-only states, such as Washington, are usually faster than exam-based states.
