Home Improvement Contractor License Requirements by State [Guide]

Looking to obtain a new license for your home improvements business? Here is a state-by-state listing of the general requirements to complete to become legal in your state.

Generally, contractors will need to fill out an application and submit or mail those documents with an application fee to state or county officials, depending on their location. Once approved, you'll have a lot more freedom to take on work.


Home improvement contractors in Alabama need to show proof of a license based on the project they are undertaking.  Industrial and commercial jobs estimated to cost at least $50,000, or residential jobs estimated to cost $10,000 or more require a license.

Swimming Pools

With swimming pools, anything over an estimated $5,000 requires a license.

The Alabama Licensing Board for General contractors has reciprocity with Mississippi, Tennessee, Arkansas, and Louisiana.


In Alaska, home improvement contractors need to successfully pass the Alaska Craftsman Home Program or show proof of having completed post-secondary Arctic engineering. Alaska requires a separate license for home and commercial contracting work. There’s also a lesser certification called the Residential Contractor Endorsement, which requires a 16-hour long cold climate course. 

Handyman contractors may perform work on projects with an aggregate contract of $10,000 or less for each project. This aggregate total is to include all labor, materials and other items for that site or project

Contractors working with dangerous paint, boilers, and explosives, among others, need to show a business Certificate of Fitness for the Trades.


Similar to Alaska, Arizona requires that a home improvements contractor have two separate licenses to undertake commercial and residential projects. 

Any business which contracts or offers to contract to build, alter, repair, add to, subtract from, improve, move, wreck or demolish any building, highway, road, railroad, excavation or other structure, development or improvement, or to do any part of the work, must be a licensed contractor.

Also included in work requiring a license is the erection of scaffolding, connections to utility service lines, metering devices and sewer lines, mechanical or structural service to a structure or improvement, and any other work in connection with the project.

The term "home improvement contractors" includes subcontractors, floor covering contractors, hardscape contractors, and consultants representing themselves as having the ability to supervise or manage a construction project for the benefit of the property owner.

Generally, if labor and materials exceed $1,000 OR a permit is required (regardless of the price of labor and materials), then a license is required. Please read the Arizona Revised Statutes on "Persons not required to be licensed; penalties; applicability" ARS §32-1121.

Contractors must be properly licensed before submitting bids.

Work-related to electrical, plumbing, air conditioning systems, boilers, swimming pools, spas, and water wells must be subcontracted to an appropriately licensed contractor. 

Alternatively, for projects that cost more than $750, professionals must have a license. 


In Arkansas, if the job costs less than $2,000, then a license is not needed. However, for projects equalling or exceeding that amount, it is legally mandated that the contractor be licensed. If the general license is not in possession of one, then the responsibility falls on the subcontractor to get the necessary qualifications. See the generally applicable statutes governing residential contracting licensing here. 


For the most part, for projects that cost more than $500 in California, the contractor must have a license - in most cases as a residential remodeling contractor. In these cases, you will be required to take a licensing examination. To be safe, it is best to confer with the legal authorities to determine the procedure that you should adopt. 


Unlike most states, Colorado’s contractors’ licenses are administered at the local level, rather than the state level. Contractors must obtain a business license, one which is different from a contractor’s license. 


In Connecticut, there's a home improvement contractor registration requirement if: 

  • You perform work on residential property (single or multi-family dwellings of six units or less), condominiums, or common interest communities; and

  • You charge more than $1,000 for home improvement contracts during any 12 consecutive months.

You do not need to be registered as a Home Improvement Contractor if:

  • You work only as a subcontractor for a registered Home Improvement Contractor;
  • You only build new houses;
  • You only do commercial work; or
  • You hold a trade license issued by the state, and the work you are doing is within the scope of that license. Requirements for New Home Construction Registrations

A home improvement contractor who does new homes must obtain a New Home Construction Contractor registration from the Department of Consumer Protection. This is a separate registration from a Home Improvement Contractor. If you get both registrations, you will not have to pay the registration fee for the New Home Construction Contractor registration, but you will have to pay into the New Home Construction Guaranty Fund.

For more information, download the Connecticut Home Improvement and New Home Construction Handbook for Contractors.


Delaware law defines contractors as “every person engaged in the business of Furnishing labor or both labor and materials in connection with all or any part of construction, alteration, repairing, dismantling or demolition of buildings, structures, driveways, roads, bridges, viaducts, sewers, water and gas mains and every other type of structure as an improvement, alteration or development of real property.”

In Florida, contractors may choose between registered and certified licenses to work in compliance with State Law.

Applicants must pass the Florida Contractor License exam or obtain a Certificate of Competency from their local government licensing authority.

Contractors’ license applicants must show proof of four years’ work experience demonstrating experience in the field corresponding to the license applied for.

The same goes for fences, landscaping contractors, and so on.

For certified contractors, this work experience should include a minimum of 1 year of supervisory experience. Some licenses require further evidence of specific experience. These include the Florida General Contractor License and the Residential Contractor License.
