In Texas, there is no state license for mechanical auto repair. In Michigan, the state licenses the shop and the mechanic across 12 specialty categories. Arizona and Tennessee require nothing at the state level. Whether you need a license depends entirely on which side of a state line you park the lift.
⚠️ Accuracy note. Everything below was read in the primary source, and the source is linked in each case, as of July 2026. Statutes get amended, agencies reorganize, and court dockets move. Before you set shop policy or spend money on the strength of any of it, open the linked source and confirm it is still current. This is reporting, not legal advice. Your state agency and your attorney are the authorities, not this article.
That opening is the whole article in miniature. Texas is where this question gets searched most, and the verified answer is the opposite of what almost everyone expects: for mechanical repair, the state does not license you. Body shops are a separate matter, and there is a records rule nobody mentions, but the license everyone is worried about does not exist there.
Everything below was read in each state’s own statutes and administrative code, not summarized from a directory. Two warnings before the table, and both matter more than the table does.
First: 22 states were not researched. If your state is not named here, this article does not answer your question and you should not assume anything from a neighboring state.
Second: local requirements exist everywhere. Even where the state licenses nothing, your city or county almost certainly requires a business license, zoning approval for automotive use, a fire inspection, and sign permits. Environmental registration for used oil, solvents and waste is a separate track again. Call your city or county clerk and your state agency before you sign a lease. Nothing here is legal advice.
The short version
- Texas: no state license for mechanical repair. Body shops register at $50 a year, and repair records must be kept for 1 year.
- Michigan is the heaviest in the country: it licenses the shop ($100 to $500, scaled by revenue) and certifies the mechanic ($25 certificate, $18 exam) across 12 categories, with recertification every 5 years in areas including tune-up, electrical and brakes, and a 3-year records rule.
- Arizona and Tennessee: nothing found at the state level. No board, no registration for independent mechanical repair.
- Hawaii, Connecticut, New York and Nevada all license or register shops, with Connecticut requiring a $25,000 bond and Nevada a $5,000 bond.
- Several states license only body shops or glass, which is why owners get contradictory answers: New Jersey, Rhode Island, Utah, Massachusetts and Texas.
- Pennsylvania is the most common false positive. The state certifies inspection stations. That is not a repair shop license, and shops that do not perform state inspection need no state credential.
Auto repair shop license by state: who licenses, who registers
Hawaii licenses both the repair shop and the mechanic. Registration runs $224 to $368, renewal $288. Written estimates required for every job with no dollar floor, records kept 2 years.
Connecticut requires a repairer’s license at $340, renewed every two years, backed by a $25,000 bond, plus a 24 by 36 inch consumer rights sign with prescribed text in every area where repair orders are written.
New York requires registration: $10 plus $150 per location, valid two years, with the most demanding signage in the country, including an exterior sign 3 feet by 2 feet, green with white lettering.
Nevada requires DMV registration at $25 plus a $5,000 bond, and a consumer sign 22 by 28 inches carrying the Great Seal of the State.
Florida registers shops by employee count at $50, $150 or $300, under Fla. Stat. 559.905.
California licenses repair dealers through the Bureau of Automotive Repair.
Michigan is in a class of its own, described above.
The states that license only part of the trade
This is where most of the confusion online comes from, because a page saying “State X requires a license” is often true for collision and false for mechanical.
- New Jersey: body shops only, $20 plus $350, biennial. Body shop records kept 2 years.
- Massachusetts: collision and glass only, $450 for 3 years with a $10,000 bond, records 18 months.
- Rhode Island: body shops only, $300 per year per location, records 2 years.
- Utah: body shops only, with a $20,000 bond.
- Texas: body shops only, $50 a year. Mechanical repair, nothing.
The states with no state license for repair shops
Verified as no license requirement for independent mechanical repair: North Carolina, Washington, Colorado, Maryland, Virginia, Pennsylvania, Arizona, Tennessee, Oregon, Louisiana, Wisconsin, Minnesota, Ohio, Illinois, Indiana and Missouri.
Two of those deserve a note.
Indiana and Missouri were confirmed by absence: auto repair does not appear on Indiana’s list of 40 licensed professions or among Missouri’s 39 licensing boards.
Pennsylvania is the trap. Pennsylvania certifies safety inspection stations, and an inspection station certificate is not a repair shop license. If you are not performing state inspections, you need no state credential. Any source telling you “Pennsylvania requires a license” has almost certainly confused the two.
No state license does not mean no obligations
This is the part that gets people in trouble, because “Texas doesn’t license me” quietly becomes “nobody regulates me,” and that is wrong in three separate ways.
Records. Michigan requires 3 years. New York, Hawaii, Wisconsin, Illinois, Rhode Island and New Jersey body shops require 2 years. Texas, Washington, Nevada and Minnesota require 1 year. That obligation exists whether or not anyone issued you a license, and it is the most-ignored rule in the trade. Keeping every repair order, estimate and invoice retrievable by vehicle for the required period is the compliance floor, and any shop management system worth using keeps them retrievable by vehicle, ours included.
Estimates and authorization. Most of these states regulate when you must give a written estimate and how far above it you may go. The rules are wildly inconsistent and getting them wrong is a consumer protection problem regardless of licensing. That is a subject of its own, covered in can a shop charge more than the estimate.
Consumer rights signage. Connecticut, New York, Nevada, Washington, Hawaii, Virginia, Rhode Island, New Jersey and Pennsylvania all prescribe posted notices, several with exact dimensions and literal text. A shop can be unlicensed by design and still be out of compliance for a missing sign.
Returned parts. Maryland, Virginia and Michigan require the old parts be offered back without the customer asking. New York requires a written request before work begins; New Jersey, Connecticut, Pennsylvania and Massachusetts require a request. Illinois gives no such right at all.
Environmental. Used oil, antifreeze, solvents, brake dust and tires are regulated federally and by every state. In Texas there is an administrative program under the TCEQ often cited for repair shops; we were not able to confirm its specifics, so verify it with the TCEQ directly rather than treating it as a stated requirement. That caveat applies broadly: environmental registration is the piece most likely to catch a new shop, and the piece least likely to be described accurately on any blog, including this one.
What to actually do before you open
Six calls, in this order.
- Your state’s licensing agency, usually the DMV, the department of motor vehicles equivalent, or a consumer affairs bureau. Ask specifically about mechanical repair, separately from collision.
- Your city or county clerk, for the general business license.
- Zoning, before the lease. Automotive use is restricted in a lot of commercial zones, and this is the one that kills deals.
- Fire marshal, for flammable storage and spray operations.
- Your state environmental agency, for used oil, waste and air permits.
- An insurance broker, for garage liability and garagekeepers coverage, which is not the same as general business liability.
Ask each of them to put the answer in writing or send you the form number. Verbal answers from a phone queue are not a defense.
Frequently asked questions
Do you need a license to open an auto repair shop in Texas?
Not for mechanical repair. Texas has no state license for it. Body shops register at $50 a year, and repair records must be kept for 1 year. Local business licensing, zoning and environmental rules still apply, so confirm with your city and with the TCEQ.
Which state has the strictest auto repair licensing?
Of the states verified, Michigan. It licenses the shop, scaled by revenue from $100 to $500, and separately certifies mechanics across 12 specialty categories with a $25 certificate and an $18 exam, requiring recertification every five years in areas including tune-up, electrical and brakes.
Do I need a mechanic license, or just a shop license?
It depends on the state and most do not require a personal credential at all. Hawaii and Michigan license both the business and the individual mechanic. ASE certification is a separate, voluntary industry credential: it requires two years of experience and is valid for five years, and no state substitutes it for a license.
Does Pennsylvania require an auto repair shop license?
No. Pennsylvania certifies vehicle safety inspection stations, which is a different credential. A shop that does not perform state inspections needs no state repair license. This is the most common misstatement in online guides.
Bottom line
There is no national answer, and the spread is not subtle: Michigan licenses the shop and the mechanic in 12 categories, while Texas, Arizona and Tennessee license neither. The states in this article were read in their own statutes. The 22 states not named here were not researched, and local requirements exist in all 50.
Before you sign a lease, make the six calls above and get the answers in writing. Then keep your repair records for at least as long as your state requires, because that rule applies to you whether anyone licensed you or not.
