Classes and rules by state
Every hands-on class we list, state by state, with the licensing summary.
Licensing
Whether you need a contractor license to install epoxy floors depends on your state and often on the size of the job. Arizona and California license coating work from $1,000; Texas and Ohio have no state license for it. Here is every state and DC, with the board, the classification and the threshold.

Not legal advice. These are the rules as of October 2026. Licensing laws change, and cities and counties add their own. Before you quote, confirm with the board linked in your state's row and with your city or county.
All 50 states and DC
Yes: a state license or registration applies to most paid coating jobs. Depends: it applies only to some jobs (home-improvement work, large projects or certain counties). No state license: the state doesn't license this work, though cities, counties and permits may still apply.

How to read the table
Then check the city. A state with no contractor license can still have a city or county that requires one, and many cities and counties require a business license or tax registration to operate at all.
Licensing is the first step of the Set Up system. Our guide to starting an epoxy flooring business puts it in order with the LLC, insurance and equipment, and the startup cost calculator adds the fees to your budget.
What usually triggers licensing
Some states license nearly all construction work and exempt only small jobs. Arizona exempts work under $1,000 including labor and materials, unless the job needs a local building permit or is part of a larger project. California raised its small-job limit from $500 to $1,000 on January 1, 2025, and the exemption doesn't apply if the job needs a permit or if anyone works for you on it. Washington registers every construction contractor, whatever the job size.
Several states license or register only contractors who work on homes, so a homeowner's garage floor can need a license that a warehouse floor doesn't. Arkansas requires a home improvement license for specialty work such as flooring and painting on a house above $2,000. Tennessee requires one from $3,000 in nine counties, including Davidson (Nashville), Shelby (Memphis) and Knox (Knoxville).
States that license trades put floor coatings in a specialty class, and the names vary. Arizona's Floor Covering classes (R-8, C-8, CR-8) list "concrete coatings" and its Painting and Wall Covering classes list "liquid floor and wall coatings." Alaska's Painting Contractor class names "epoxies." Tennessee has BC-4 Floor Covering and BC-14 Special Coatings and Waterproofing. California is the hardest case; see below.
Some states license only big jobs: North Carolina from $40,000, Tennessee from $25,000, Alabama's commercial board from $100,000. Others have no state license for this work. Texas has none for general, flooring or coating contractors, and Florida went further: since July 1, 2025 its counties and cities may not require a local license for painting or flooring either.
The hardest case
No CSLB classification names epoxy floors, and coating companies in California hold at least three different ones. Here is what each covers:
You will see coating companies claim that only one of these is legal for epoxy floors. The classification definitions don't say that. Describe the systems you install when you apply, and ask CSLB which classification fits before you sit the exam.

Questions
It depends on the state, and often on the job. Some states license nearly all construction work above a small dollar amount (Arizona and California from $1,000), some license only home-improvement work or only large projects, and some, such as Texas and Ohio, have no state license for flooring or coating work. Find your state in the table and confirm with the board before you quote.
No CSLB classification names epoxy floors. C-15 Flooring and Floor Covering covers "any other materials established as flooring," C-33 Painting and Decorating covers materials that "adhere by evaporation," and the C-61/D-12 Synthetic Products listing names "resin and epoxy application." Coating companies hold all three. Describe the systems you install when you apply and ask CSLB which classification fits.
Many states exempt small jobs, but the exemptions are narrow. In California and Arizona the exemption ends at $1,000 including labor and materials, and it does not apply if the job needs a building permit; in California it also ends the moment you use a worker. Splitting a job into smaller contracts to stay under a threshold is not allowed anywhere.
No. Texas has no state license for general, flooring or coating contractors. Florida licenses construction trades through its Construction Industry Licensing Board, but flooring and painting are not state-licensed categories, and since July 1, 2025 Florida counties and cities may not require their own license for them.
No. A certificate of completion or a manufacturer approval shows training on a product; a license is legal permission from the state. Where your state requires a license, you need it regardless of training. See what epoxy flooring certification exists.
Yes, often on January 1 or July 1. California raised its small-job limit from $500 to $1,000 in 2025, Alabama raised its commercial threshold from $50,000 to $100,000 in 2024, and Florida ended local flooring and painting licenses in 2025. Always confirm with the board linked in your state's row before you rely on it.
