There's no single national license for general contractors in the United States. Each state sets its own rules — and the differences are significant. Some states require a statewide license with a written exam and proof of experience. Others leave licensing entirely to counties or cities. A few states don't require a general contractor license at all for residential work, though local jurisdictions may still demand permits and registration.
Understanding where your state falls on this spectrum isn't just a formality. Working without the required license can mean fines, stop-work orders, and personal liability for construction defects. It can also void your contracts and make you ineligible for certain bids. Getting licensed protects you, your clients, and your business.
This guide breaks down what most states require, highlights the variation you'll encounter, and gives you the key categories to investigate when researching your specific state's rules.
Even with all the variation, most states that issue statewide contractor licenses look for some combination of the following:
This is nearly universal. Most states want to see that you've worked in construction — typically as a journeyman, foreman, or project manager — for a set number of years. The requirement commonly ranges from two to four years of documented field experience. Some states accept a combination of formal education (like a construction management degree) plus experience.
"Experience" usually means hands-on work, not just owning a business or supervising at arm's length. You'll typically need references from employers or clients who can attest to your direct involvement in construction projects.
Many states require passing one or more written exams. These tests typically cover two areas: trade knowledge (construction methods, codes, materials, project management) and business and law (contracts, liens, worker's comp, OSHA basics). Some states use exams administered by testing providers like PSI, Prometric, or the National Center for Construction Education and Research (NCCER).
The general contractor license requirements in your state will specify which exam, what passing score you need, and how many attempts you're allowed.
Most states require proof of general liability insurance — often a minimum of $300,000 to $1 million per occurrence. Many also require a surety bond, which protects clients if you fail to complete a job or cause damage. Bond amounts vary widely, from $5,000 in some states to $75,000 or more in others.
Some states run criminal background checks as part of the licensing process. Felony convictions related to fraud, theft, or certain violent crimes may disqualify an applicant, though policies vary. Having a past conviction doesn't automatically bar you — it depends on the state and the nature of the offense.
Licensing fees range from under $100 to several hundred dollars depending on the state and license type. Renewal fees are usually lower than initial application fees. Budget for both the application cost and any required exam fees, which are typically charged separately.
Rather than listing all 50 states in full detail (requirements change frequently and official state boards are the authoritative source), here's an overview of how states typically cluster:
States like Florida, California, North Carolina, South Carolina, Tennessee, and Nevada maintain robust statewide licensing systems. These states have clear exam requirements, experience thresholds, and centralized licensing boards.
Florida, for example, requires passing the Florida State Certified Contractor exam, four years of experience (or a combination of education and experience), financial statements, and proof of insurance. The state offers both a "Registered" contractor license (valid in specific counties) and a "Certified" license (valid statewide).
If you're pursuing a general contractor license in Florida, expect a rigorous application process — but also a license that opens doors across the entire state.
Several states delegate licensing authority to local governments. Alabama, for instance, has statewide licensing for commercial projects over $50,000 but largely leaves residential work to counties. Colorado has no statewide general contractor license — licensing is entirely local.
In these states, requirements can vary dramatically from one county to the next. Always check with your specific county or city building department in addition to any state-level requirements.
Some states use a registration system rather than a full license. Registration typically means you're listed with the state and have met basic insurance requirements, but you haven't necessarily passed an exam. Texas and Washington are examples where contractor registration is required but a trade exam isn't mandatory for general contractors (though specialty trades like electrical and plumbing still require full licenses).
A handful of states — including Montana, Missouri, and Kansas — have minimal or no statewide general contractor licensing requirements for most residential work. Local jurisdictions may still require permits, and specialty trades (electrical, plumbing, HVAC) are almost always licensed separately regardless of state.
Even in these states, getting licensed or registered voluntarily — or at least carrying proper insurance — is strongly advisable for liability reasons and client trust.
A few states generate the most questions because of their large contractor workforces and complex licensing systems. Here's a quick breakdown:
Florida has one of the most structured systems in the country. The Certified license requires: four years of experience (with at least one year as a foreman or supervisor), passing both a trade exam and a business and finance exam, proof of insurance and workers' comp, and a credit check. You'll apply through the Florida Department of Business and Professional Regulation (DBPR).
The state also has a lower-tier "Registered" option for contractors who want to work only within specific jurisdictions that have approved them — useful if you're building a local business and don't need statewide scope yet. If you need a Florida general contractor license, plan for a 60–90 day application timeline.
North Carolina licenses general contractors through the NC Licensing Board for General Contractors. The license is tiered by project size: Limited (projects up to $500,000), Intermediate (up to $1 million), and Unlimited. Higher tiers require more experience and a higher-stakes exam.
You'll need to pass a written exam, submit a financial statement, and show proof of experience. The Intermediate and Unlimited licenses also require a CPA-reviewed or audited financial statement showing adequate capital. If you want to get a general contractor license in NC, start with your target tier and work backward to meet the financial and experience requirements.
Georgia's licensing board oversees residential and commercial contractor licenses separately. Commercial general contractors must be licensed by the state; residential contractors handle projects over $2,500 and must also be licensed. Both require a written exam, experience documentation, and insurance proof.
Georgia also requires financial statements reviewed by an accountant — another common requirement for higher-value license tiers. The process of becoming a general contractor in Georgia takes most applicants two to three months from application submission to license issuance.
South Carolina requires all general contractors working on projects over $5,000 to be licensed by the SC Contractor's Licensing Board. The state administers a business law exam, and you'll need to document experience and carry insurance. The South Carolina general contractor license process includes submitting references from past employers or clients who can verify your construction experience.
Arizona's Registrar of Contractors (ROC) handles licensing for both residential and commercial contractors. Dual licensing (residential + commercial) is available. Applicants must pass a business management exam (not a trade exam — Arizona notably doesn't require a trade exam for GCs), prove experience, carry insurance, and post a bond. The Arizona general contractor license requirements are generally considered more straightforward than some other large states.
Regardless of your state, the general process for getting licensed follows a similar arc. Here's how to approach it:
Step 1: Confirm your state's authority. Look up your state licensing board — usually housed in a Department of Labor, Commerce, or Consumer Protection. Verify whether licensing is statewide, local, or both for your intended type of work (residential vs. commercial).
Step 2: Check classification and tier. Many states offer multiple license classes based on project size, project type (residential vs. commercial), or specialty. Identify which tier fits your intended business scope.
Step 3: Document your experience. Gather employment records, tax records, and references that prove your years in construction. Some states have specific forms for this — download and complete them early since tracking down old employers takes time.
Step 4: Get your financial documents in order. States that require financial statements (common for higher-tier licenses) need these prepared by a licensed CPA. Start this process early — accountants have lead times, and you don't want this to delay your application.
Step 5: Register for and pass the exam. Identify which exam(s) your state requires, register with the testing provider, and begin studying. The business and law portion trips up many applicants — don't neglect it in favor of trade knowledge prep.
Step 6: Secure insurance and a bond. Get quotes from insurance agents who specialize in contractor liability. Confirm coverage minimums with your state board before purchasing so you don't have to get additional coverage later.
Step 7: Submit your application. Most state boards have online application portals. Assemble all required documents before starting — incomplete applications slow things down significantly. Pay your application fee and track your application status.
The general contractor license study guide on this site covers exam prep for the trade knowledge and business law sections you'll face in most states.
Processing times vary by state. Fast states can issue licenses in a few weeks; slower states (or those with lengthy background check processes) may take 60–90 days. Exam scheduling adds time too — popular testing centers may have wait times of two to four weeks for available slots.
Realistically, plan on three to six months from decision to licensed status if you're starting from scratch. If you need to accumulate experience hours, add that time on top. Use that runway to get your insurance, bonding, and business registration sorted so you're ready to operate immediately once the license arrives.
The single most important step you can take is going directly to your state's licensing board website. These change frequently — requirements shift, new laws take effect, and fee schedules update. A licensed contractor from two years ago may find their renewal process looks different today.
Supplement your research with practice tests and study guides targeted to your state's specific exam. The Oklahoma general contractor license exam, for instance, covers state-specific code references that you won't find in generic study materials.
Getting your general contractor license is a meaningful milestone — it opens commercial bids, larger projects, and the kind of client trust that repeat business runs on. The licensing process is a hurdle, but it's a navigable one. Start with your state's official board, document everything carefully, and use quality practice materials to prepare for the exam. You've got this.
