What license do you need to open a mechanic shop? The checklist, state by state
To open a mechanic shop in the US you need a business license from your city or county, a sales tax permit from your state, and, in some states, a state registration or license for the repair shop itself (California, Connecticut, Florida, Hawaii, Michigan and New York are examples). The building must be zoned for auto repair, and your techs need EPA Section 609 certification to work on AC. Most states don't license individual mechanics, though a few do, and inspection or emissions work needs its own station license.
Below: the full checklist, the states that register shops with their agencies, the certifications your techs may need, the order to apply in, and what changes for a mobile mechanic.
The checklist: what almost every shop needs
| License or permit | Who issues it | Needed when |
|---|---|---|
| Business entity (LLC or corporation) and a registered name | Your Secretary of State | Optional but common; a "doing business as" name if you trade under another name |
| Employer Identification Number (EIN) | IRS, free online [1] | You have employees or an LLC with partners; banks usually ask for it |
| Business license | City or county | Nearly everywhere |
| Zoning approval and certificate of occupancy | City or county planning and building department | Before you sign a lease or open; repair is often limited to certain zones |
| Sales tax permit | State revenue department | You sell parts (and in some states, labor is taxed too) |
| State repair shop registration or license | Varies (see the state table below) | In states that register shops |
| EPA Section 609 certification | EPA-approved training programs [2] | Anyone servicing vehicle AC for pay |
| EPA ID number for hazardous waste | Your state environmental agency (EPA Form 8700-12) [3] | If you generate enough hazardous waste to be a small or large quantity generator; some states require it for all generators |
| Fire department permit or inspection | Local fire marshal | Common for shops storing fuel, oil, paint or compressed gases |
| Sign permit | City | Before putting up an outdoor sign |
| Inspection or emissions station license | State agency that runs the program | Only if you do state inspections or emissions tests |
Insurance isn't a license, but your landlord, your state's workers' compensation law (once you have employees) and some registrations will require it. Garagekeepers coverage protects customers' cars in your care; general liability usually doesn't.
States that register or license repair shops
There's no national license to open a repair shop. Some states register the shop; most don't. These are examples, with the official agency to check; rules and fees change, so confirm with the agency before you apply.
| State | What the shop needs | Agency |
|---|---|---|
| California | Automotive Repair Dealer registration before doing repairs for pay; separate licenses for Smog Check and brake and lamp stations | Bureau of Automotive Repair [4] |
| Connecticut | A general or limited repairer license from the DMV; the DMV lists a $340 fee for a general or limited repair license and a $25,000 surety bond for a general repairer, with building official and fire marshal sign-off on the application | Department of Motor Vehicles, Dealers and Repairers Licensing [5] |
| Florida | Anyone paid to repair other people's vehicles must register as a motor vehicle repair shop | Department of Agriculture and Consumer Services [6] |
| Hawaii | Motor vehicle repair dealer registration; the dealer must be or employ a full-time licensed mechanic, and mechanics themselves are registered or certified by the board | Motor Vehicle Repair Industry Board, DCCA [7] |
| Michigan | Repair facility registration, and certified mechanics for many categories of repair | Department of State [8] |
| New York | Repair shop registration before doing repairs for the public | Department of Motor Vehicles [9] |
| Texas | No state license to open a general repair shop; a vehicle inspection station needs a DPS station license ($100 to apply, per DPS) and a certified inspector | Department of Public Safety [10] |
Some cities add their own repair license on top of the state's. If your state isn't listed, call its consumer protection office or motor vehicle department and ask: "What does an auto repair shop need to register here, and do you require a bond?" Then ask your city the same about local licenses. For California in full, read our guide on how to open an auto repair shop in California.
Does the mechanic need a license?
In most states, no: the shop is regulated, not the person. Exceptions and special cases:
- Michigan requires mechanics to be certified by the state for the categories of repair they do [8].
- Hawaii registers or certifies mechanics through its Motor Vehicle Repair Industry Board, and a repair dealer must be or employ a licensed full-time mechanic [7].
- AC work everywhere: Section 609 certification is a federal requirement for anyone servicing motor vehicle AC for pay [2]. The training and test are short and inexpensive; AutoLeap lists the exam at about $20 [11].
- Inspections and emissions: states that run inspection or emissions programs certify the inspectors as well as the station.
- ASE certification is voluntary in most states but widely used by shops to show training, and some programs and employers require it.
Our list of auto repair shop services notes which services need extra certification or equipment before you offer them.
Zoning: check it before the lease
Zoning is where new shops get stuck most often, and it's the one to check first. Auto repair is often allowed only in commercial or industrial zones, sometimes only with a conditional use permit and a public hearing. Before you sign:
- Give the city planning department the exact address and ask whether "auto repair" or "vehicle service" is allowed there, by right or with a permit.
- Ask what a change of use would need if the building wasn't a repair shop before: parking spaces, fire separation, floor drains, ventilation.
- Ask about outdoor work and car storage rules: many cities ban repairs outside the building and limit how many cars can wait on the lot.
- Get the answers in writing, or write the lease so it starts only once the permits are granted.
A building that was a repair shop recently is usually the easiest, but the use may have lapsed if it sat empty; ask.
Environmental rules from day one
- Used oil and filters: store in closed, labeled containers and send them to a used oil collector or recycler [12].
- Hazardous waste: solvents, some brake cleaners and other waste have handling rules by generator size. Small and large quantity generators need an EPA ID number, filed with your state on Form 8700-12; there's no federal fee, and some states charge their own [3].
- Refrigerant: certified techs and approved recovery equipment [2].
- Floor drains: many areas restrict drains connected to sewers or the ground; ask your water authority.
The order to apply in
- Pick the business structure and name, register them with your state, and get an EIN [1].
- Check zoning for the address before signing anything.
- Sign the lease (ideally with a permit contingency).
- Apply for the state shop registration if your state has one, with any bond it asks for. Some states want the location's address on the application, so this comes after the lease.
- Get the city or county business license, the certificate of occupancy, the fire inspection and the sign permit.
- Register for sales tax.
- Arrange insurance and, once you hire, workers' compensation.
- Set up waste handling: a used oil hauler, an EPA ID if you need one, and certified techs for AC.
- Post what your state requires in the shop: some states require the registration certificate or the labor rate to be displayed (Connecticut, for example, requires the hourly labor rate on a sign [5]).
Licensing is one step in a longer list; our guide on how to start an auto repair shop puts it in order with the plan, the building and the equipment, and how much it costs to start an auto repair shop gives the budget, including the permits line.
What licenses and permits cost
Fees vary by state and city. Published examples: AutoLeap puts a general business license at $50–$500 depending on location [11]; Connecticut's DMV lists $340 for a repair license plus a $25,000 bond [5]; Texas DPS lists $100 for an inspection station license [10]; Hawaii's board lists a repair dealer renewal fee of $288 [7]. A bond is usually bought from a surety company for a yearly premium that's a fraction of the bond amount. Budget a few hundred to a few thousand dollars in total, then get the real figures from your own state and city.
Mobile mechanics
A mobile mechanic usually still needs a business license, a sales tax permit if selling parts, and, in states that register repair businesses, the same registration (Hawaii, for example, requires a dealer's mobile repair facility to be registered with the board [7]). Without a building, zoning and the certificate of occupancy usually drop away, but some cities limit repair work on streets or in parking lots. You'll also want commercial auto insurance for the van.
After you're licensed: tell customers
A registration number is something drivers can check, and in some states your estimates and invoices must show it. Put it, with your certifications, on your invoices, your Google Business Profile and your website.

FAQ
Do I need a license to open a mechanic shop?
You need a local business license almost everywhere, and a state shop registration in states such as California, Connecticut, Florida, Hawaii, Michigan and New York.
Do I need to be a certified mechanic to own a shop?
Usually not. Owners don't need to be mechanics in most states, but Hawaii requires the dealer to be or employ a licensed mechanic, and Michigan requires certified mechanics for many repairs [7][8].
What permits do I need to open a mechanic shop?
Zoning approval and a certificate of occupancy, a fire permit or inspection, a sign permit, a sales tax permit, and environmental registrations if you generate hazardous waste.
Is ASE certification required?
Not by law in most states. It's voluntary, though widely used to show training.
Do I need a license to work on cars from home?
If you're paid, you're usually a business: a business license, and a state registration where one applies. Home zoning often bans auto repair, so check with your city.
How long does it take to get licensed?
A business license can take days; state registrations and certificates of occupancy can take weeks. Start zoning and state registration first.
