Do I Need a Contractor License? State-by-State Requirements (2026)

It's one of the most common questions in the construction industry: do I need a contractor license to do this work? The answer depends on your state, the type of work, and, in many cases, the dollar value of the project.

Get it wrong, and you could face fines ranging from $500 to $50,000, criminal charges, and the inability to collect payment for work you've already completed. Get it right, and you're protected, credible, and able to bid on bigger projects.

This guide breaks down the rules state by state so you know exactly where you stand.

The Short Answer

In most states, yes, you need some form of contractor license to perform construction work above a certain dollar threshold. But the specifics vary dramatically:

• Some states require a license for any construction work, regardless of project size
• Some states set a dollar threshold, work under that amount doesn't require a license
• A few states have no statewide contractor licensing at all (though cities and counties may require it)
• Nearly all states require trade-specific licenses for electrical, plumbing, and HVAC work regardless of project value

State-by-State Threshold Amounts

Here's what triggers the licensing requirement in each state. If your project exceeds the threshold, you need a license.

States With No Dollar Threshold (License Always Required)

These states require a contractor license for virtually all construction work:

• Florida, All construction work requires a state-certified or state-registered contractor license. No threshold exemption.
• California, Any project valued over $500 (including labor and materials) requires a CSLB license. This is effectively no threshold for any real project.
• Nevada, All construction work requires a license from the Nevada State Contractors Board. No dollar exemption.
• Arizona, Any project involving a structure requires a license from the Registrar of Contractors. Residential and commercial.
• Louisiana, Any project over $7,500 requires a license. Residential projects over $7,500 also require registration.

States With Moderate Thresholds

• Georgia, Projects over $2,500 require a license for general and specialty contractors
• North Carolina, General contractors need a license for projects over $30,000. Plumbing, electrical, and HVAC have separate licensing regardless of project size.
• Tennessee, License required for projects over $25,000
• Virginia, Class C license for projects $10,000–$120,000; Class B for $120,000–$500,000; Class A for over $500,000
• South Carolina, General contractors need licensing for projects over $5,000
• Michigan, Residential builders and maintenance/alteration contractors need licensing for projects over $600

States With Higher Thresholds

• Alabama, License required for projects over $50,000 (one of the highest thresholds in the country)
• Mississippi, Projects over $50,000 require licensing
• Oregon, License required but with a $500 bonding threshold for residential; commercial has different rules

States With No Statewide General Contractor License

These states don't require a statewide general contractor license, but don't celebrate yet, cities, counties, and specialty trades almost certainly have requirements:

• Texas, No statewide GC license, but electrical, plumbing, and HVAC all require state licenses. Many cities (Houston, Dallas, San Antonio, Austin) require local permits and registrations.
• Colorado, No statewide GC license, but electrical and plumbing require state licenses. Most municipalities have their own requirements.
• Kansas, No statewide licensing. Local jurisdictions set their own rules.
• New Hampshire, No statewide GC license, but electrical and plumbing require state licenses.
• Vermont, No statewide licensing for general contractors. Electrical contractors need state licensing.
• Missouri, No statewide GC license. St. Louis and Kansas City have local requirements.

Important: Even in states without statewide licensing, you almost always need a business license, and specialty trades (electrical, plumbing, HVAC, roofing) typically have their own licensing requirements.

When Specialty Trade Licenses Are Required

Regardless of your state's general contractor threshold, certain trades almost universally require their own license:

Electrical Work

Virtually every state requires an electrical license. Even states without general contractor licensing (like Texas and Colorado) require licensed electricians. The threshold for electrical work is usually $0, any electrical work requires a license.

Plumbing

Similar to electrical, plumbing work requires licensing in nearly every state. Most states have a tiered system: apprentice → journeyman → master plumber. You typically need at least a journeyman license to work independently.

HVAC

Most states require HVAC licensing, though about 18 states don't have a state-level HVAC license (work falls under general mechanical or contractor licenses instead). All HVAC technicians need EPA Section 608 certification regardless of state licensing.

Roofing

Many states require a separate roofing license or registration. Florida, California, and Nevada all require specific roofing classifications.

Common Exemptions

Most states carve out exemptions for certain types of work. Common exemptions include:

Homeowner exemption, In many states, homeowners can perform work on their own primary residence without a contractor license. However, this usually doesn't apply to electrical, plumbing, or HVAC work, and the home typically cannot be sold within a certain period (often 1-2 years) after the work is completed.

Minor repairs, Some states exempt routine maintenance and minor repairs that don't affect the structural, mechanical, or electrical systems of a building.

Handyman work, Several states allow unlicensed individuals to perform minor work below a dollar threshold. California sets this at $500, while other states may go higher. See our guide on Contractor vs Handyman for more details.

Agricultural buildings, Farm structures are exempt from contractor licensing requirements in some states.

What Happens If You Work Without a License?

The consequences of unlicensed contracting vary by state but can be severe:

• Fines: Range from $500 (first offense in many states) to $15,000+ per violation in California (increased under SB 779 in 2026)
• Criminal charges: Unlicensed contracting is a misdemeanor in most states and can be a felony for repeat offenders or large projects
• Loss of payment: In many states, unlicensed contractors cannot legally collect payment for work performed. Courts will not enforce contracts with unlicensed contractors.
• No lien rights: Without a license, you cannot file a mechanic's lien to collect on unpaid work
• Project shutdown: Building inspectors can issue stop-work orders on projects being performed by unlicensed contractors

How to Get Licensed

If you've determined you need a license, the process typically involves:

1. Meeting experience requirements, Most states require 2-5 years of documented construction experience
2. Passing an examination, Business and law exam, plus trade-specific exams in many states
3. Obtaining insurance and bonding, General liability insurance and a surety bond are required in most states
4. Submitting your application, Along with fees ranging from $100 to $700+ depending on the state
5. Background check, Most states run criminal background checks on applicants

The Bottom Line

When in doubt, get licensed. The cost of licensing ($200-$1,000 in most states) is a fraction of what you'll pay in fines, lost revenue, and legal fees if you're caught working without one. And beyond avoiding penalties, a contractor license opens doors to larger projects, better clients, and higher credibility.
