If you are a general contractor, you are responsible for ensuring projects run smoothly and that your clients and subcontractors are content with your work. Part of that may involve getting a general contractor license. Each state has different requirements. Here’s an overview of General Contractor License Requirements by State.
This guide is written as a practical overview for general contractors. It is informational only and should not replace the current state agency, local building department, or legal advice when a project is large, public, residential, or otherwise high risk.
General contractor license requirements by state
Alabama–Florida
Alabama. Alabama requires state licensing for prime contracts of $100,000 or more through the Alabama Licensing Board for General Contractors. Residential construction can also trigger separate home-builder licensing rules through the Alabama Home Builders Licensure Board.
Alaska. Alaska licenses construction contractors at the state level. General contractors may hold a residential endorsement, operate without that endorsement for work outside the endorsement scope, or register as handyman contractors for jobs of $10,000 or less.
Arizona. Arizona licenses contractors through the Registrar of Contractors, with separate commercial, residential, and dual classifications. Contractors should expect classification-specific application rules, exams, and financial-responsibility requirements.
Arkansas. Arkansas splits commercial and residential oversight. Commercial contractors generally need a license for projects of $50,000 or more, while residential builder rules apply separately and can start at much lower dollar amounts.
California. California licenses contractors through the Contractors State License Board. In general, work of $1,000 or more in combined labor and materials requires a license unless a narrow exemption applies, and the state uses distinct classifications such as General Engineering, General Building, Residential Remodeling, and Specialty.
Colorado. Colorado contractors should check the jurisdiction where the work will occur. Denver, for example, licenses general contractors, while Colorado’s DORA serves as the umbrella licensing agency for many regulated professions and businesses.
Connecticut. Connecticut is especially important for home-improvement work. The Department of Consumer Protection registers home improvement contractors, and liability insurance is part of the registration process.
Delaware. Delaware contractors must register and obtain a business license through the state’s revenue and one-stop systems. Depending on where the work is located, county or municipal rules may still add another layer.
Florida. Florida licenses contractors through DBPR. Certified licenses work statewide, while registered licenses are tied to local jurisdictions, and the main construction categories include General, Building, and Residential Contractor.
Georgia–Louisiana
Georgia. Georgia licenses residential and commercial general contractors through the Secretary of State’s board. Contractors should match the project to the correct board classification before bidding or advertising.
Hawaii. Hawaii requires contractor licensing through the Contractors License Board. A license is generally required for projects over $1,500 in labor and materials or for work that requires a building, electrical, or plumbing permit.
Idaho. Idaho uses contractor registration rather than a broad statewide general contractor license. Registration is required for construction jobs over $2,000, and residential contractors also face disclosure obligations.
Illinois. Illinois contractors need to read state and local rules together. Chicago licenses general contractors, while Illinois separately publishes licensing and permit programs for many regulated activities and trades.
Indiana. Indiana says there is no single, comprehensive business license, so contractor compliance often becomes a local or project-specific issue. Indianapolis licenses contractors, and certain public road work can involve INDOT prequalification.
Iowa. Iowa requires contractor registration for construction contractors and businesses that earn at least $2,000 per year from construction work. Some trades, including plumbing and mechanical work, are separately licensed.
Kansas. Kansas state rules clearly cover roofing contractor registration through the Attorney General and ordinary business and tax registration through the Department of Revenue. Local jurisdictions can add more; Olathe, for example, says contractors doing work in the city must be licensed there.
Kentucky. Kentucky’s statewide licensing is concentrated in specific trades such as plumbing, electrical, boiler, sprinkler, and related work. Many cities and counties also impose local business-license or occupational-tax requirements, so general contractors should verify both local and trade-specific rules.
Louisiana. Louisiana is a full licensing state. Commercial projects valued at $50,000 or more require a commercial license; residential construction or home improvement at $50,000 or more generally requires a residential license; and home-improvement work above $7,500 but not over $50,000 falls into the state’s home-improvement registration system.
Maine–Montana
Maine. Maine’s Attorney General consumer guidance says the state does not license or regulate home contractors. Even so, contractors should still verify current Maine guidance and local permit requirements before taking a residential job.
Maryland. Maryland licenses home improvement contractors through the Maryland Home Improvement Commission. For residential renovation and home-improvement work, that definition matters more than a casual “general contractor” label.
Massachusetts. Massachusetts uses two systems that contractors often confuse: Home Improvement Contractor registration and Construction Supervisor Licensing. The right credential depends on the role you are playing and the work being performed.
Michigan. Michigan licenses residential builders and maintenance-and-alteration contractors at the state level. Prelicensure education applies, so contractors should match the license to the work they actually intend to perform.
Minnesota. Minnesota licenses residential building contractors and residential remodelers who contract directly with owners for qualifying residential work involving more than one special skill. It is not just a simple registration state for residential contractors.
Mississippi. Mississippi licenses both commercial and residential contractors. Commercial jobs over $50,000 require a commercial license, while residential builder and remodeler thresholds are handled separately.
Missouri. Missouri contractors often deal with local permitting and local contractor rules, while the state separately administers a statewide electrical contractor license. Missouri law also requires political subdivisions to recognize that statewide electrical license in lieu of a local electrical license.
Montana. Montana changed its system in 2026. The former contractor registration program transitioned to a licensing program administered by the Department of Labor & Industry, so older registration-only summaries are no longer reliable.
Nebraska–Rhode Island
Nebraska. Nebraska requires contractor registration through the Department of Labor for contractors and subcontractors doing business in the state. That is a registration regime, not a traditional across-the-board general contractor license.
Nevada. Nevada licenses contractors through the State Contractors Board. Experience, qualifying-individual rules, and proper classification selection all matter before you bid or sign a contract.
New Hampshire. New Hampshire says general contractors are not required to hold a state license, although specialty trades may be regulated and businesses still have entity-registration obligations. Contractors should not read that as a free pass on permits, code compliance, or specialty licensing.
New Jersey. New Jersey requires home improvement contractor registration through the Division of Consumer Affairs. Contractors working on home improvement, repair, remodeling, or alteration of residential property should start there.
New Mexico. New Mexico requires contractor licensing through the Regulation and Licensing Department. The key compliance question is not just whether you are licensed, but whether you hold the right classification for the scope of work.
New York. New York does not use one single statewide general contractor license for every job, but it is far from unregulated. Home-improvement contractors must be licensed in several local jurisdictions, including New York City, Nassau, Suffolk, Westchester, Putnam, Rockland, and Buffalo, and covered public-works contractors and subcontractors must register with the state labor department before bidding or starting covered work.
North Carolina. North Carolina requires a general contractor license for projects costing $40,000 or more. The state board is the starting point for classifications, monetary limits, and qualifying-party questions.
North Dakota. North Dakota requires a contractor license for jobs over $4,000. The required class depends on the size and type of work.
Ohio. Ohio’s statewide licensing framework focuses on certain commercial specialty contractors, including electrical, HVAC, hydronics, plumbing, and refrigeration. City licensing still matters for many contractors.
Oklahoma. Oklahoma says general contractors are not currently required to hold a state license for general contracting. That does not remove trade licensing, permit requirements, or local city rules.
Oregon. Oregon is one of the clearest licensing states. In general, anyone working for compensation in construction activity involving improvements to real property must be licensed through the Construction Contractors Board.
Pennsylvania. Pennsylvania requires home improvement contractor registration once a contractor performs at least $5,000 of home improvements in a year. Registration, insurance, and contract requirements matter for residential remodelers and home-improvement contractors.
Rhode Island. Rhode Island broadly uses contractor registration through the Contractors’ Registration and Licensing Board, while certain specialty trades are separately licensed. Contractors should confirm whether their scope is registration-only or license-based.
South Carolina–Wyoming
South Carolina. South Carolina requires a general or mechanical contractor license for commercial construction over $10,000 in covered classifications. Older $5,000 summaries are outdated.
South Dakota. South Dakota requires a contractor’s excise tax license for anyone entering into a contract for construction, repair, or remodeling of real property. Local rules and trade-specific requirements can still apply.
Tennessee. Tennessee requires a contractor license before bidding or negotiating on projects totaling $25,000 or more. Contractors should verify classification and monetary limit before taking the job.
Texas. Texas does not require a state general contractor license, according to the Governor’s Texas Business Licenses & Permits Guide. Local requirements may still apply, and many specialty trades are separately regulated.
Utah. Utah licenses general contractors through DOPL, including classifications such as B100 General Building and R100 Residential & Small Commercial. Utah’s contractor FAQs also tie active contractor licenses to ongoing liability insurance and financial responsibility requirements.
Vermont. Vermont now requires residential contractor registration for jobs of $10,000 or more, including labor and materials. That makes older “no registration required” summaries inaccurate for residential contractors.
Virginia. Virginia licenses contractors through the Board for Contractors using Class A, B, and C structures. Pre-license education and qualification rules depend on the class and business setup.
Washington. Washington requires contractor registration through Labor & Industries, and contractors must also be bonded and insured. The L&I verify system additionally lets users check workers’ compensation status, infractions, and lawsuits against the bond.
West Virginia. West Virginia requires a contractor license for construction work when the total project cost is $2,500 or more. Applicants also face exam and related filing requirements.
Wisconsin. Wisconsin’s key statewide contractor credentialing is especially important for one- and two-family dwelling work. To obtain a building permit for that work, the business generally must hold a Dwelling Contractor credential and employ or engage a Dwelling Contractor Qualifier.
Wyoming. Wyoming directs general contractors to the local jurisdiction for licensing information rather than a single statewide general-contractor board. Local licensing exists in places such as Casper and Jackson, and public-works contractors can also seek state resident-contractor certification.
What general contractors should verify before taking a job in a new state?
Before you bid or sign, confirm four things: the state credential or registration, the local license or permit path, any specialty-trade requirements, and any insurance, bond, or workers’ compensation filings tied to the contractor record. Washington’s system shows why that matters, because the contractor record, surety bond, liability insurance, and workers’ compensation status all connect in one compliance chain. New York’s public-works contractor registry is another reminder that “no single statewide GC license” does not mean “no state-level contractor filing.”
From an insurance and risk-management standpoint, contractor licensing should be reviewed alongside entity structure, subcontractor agreements, certificates of insurance, workers’ compensation, and bond obligations. That is the practical way to reduce avoidable compliance problems before they become claim problems.
FAQ
Do all 50 states require a statewide general contractor license?
No. Texas and Oklahoma say there is no statewide general contractor license for general contracting, while Washington uses contractor registration rather than a traditional statewide GC license.
Is contractor registration the same as a contractor license?
Not always. Idaho, Iowa, Nebraska, Pennsylvania, and Washington all use registration in meaningful ways, but states such as California, Nevada, and North Carolina use traditional contractor licensing boards.
Can local rules matter even when the state does not issue a broad general contractor license?
Yes. Chicago, Denver, Olathe, Casper, and Jackson all show how local licensing can still control who can lawfully work in a jurisdiction. Wyoming’s Secretary of State even directs general contractors to the local jurisdiction for licensing information.
