Yes. A mobile mechanic is legal in New Mexico, and the state does not license auto mechanics at all. The rules that do apply come from the city, the EPA and your own lease or HOA. A real mobile business can show you its city paperwork, handles AC work with a federal card, and takes your old oil with it.
- New Mexico has no state board or license for auto mechanics.
- Rio Rancho and Albuquerque both want businesses on their city lists.
- Paid AC work needs an EPA Section 609 certified tech.
- Emissions tests in Bernalillo County only happen at Air Care stations.
- A driveway repair does not void your factory warranty.
New Mexico does not license auto mechanics. A person in Rio Rancho can buy tools, load a truck and start fixing cars for pay without a state test or a state card.
So the legal question has a short answer. Yes, mobile repair is legal here. The better question is whether the person coming to your house runs a real business. That part you can check.
No State License, and No State Board Watching
The New Mexico Regulation and Licensing Department runs the boards that license trades and professions. Its list covers barbers, home inspectors, pharmacists, real estate agents, private investigators and dozens more. There is no board for auto mechanics on it.1
That cuts both ways.
- Good news. A skilled mechanic can work on his own, at your home, with no state permit to wait on.
- Bad news. Nobody at the state checks skill before the first job. A bad mechanic and a great one look the same on paper.
Since the state does not do the checking, the city records, the reviews and the way a mechanic talks about price do the work instead. The rest of this page shows where to look.
The City Paperwork a Real Mobile Business Carries
Rio Rancho. The city asks anyone who runs a business for profit and needs a New Mexico taxpayer ID to register with the City Clerk. Businesses based outside city limits that work inside them have their own out of city registration. That one asks for a tax ID, proof of liability insurance and any state or federal license the work needs.2 The city also has an online search for active business registrations, so you can look a name up yourself.
Albuquerque. On July 1, 2025, the city swapped business registration for a business license. The fee stayed at $35 a year. The city said the change was meant to hold bad actors to account and protect customers.3
The state. An LLC shows up in the business search on the New Mexico Secretary of State website. That tells you the company exists. It does not tell you the person can fix a car.
A mechanic who works only in cash, has no business name and will not tell you where he is based is not breaking a state license law. He is just very hard to find later if the job goes wrong.
Can the Work Happen in Your Driveway?
Usually, yes. In a June 30, 2017 KRQE report, Albuquerque's planning department deputy director said owners can do routine maintenance and auto repair in a residential zone. He said it becomes a zoning problem when it turns into major repair, like pulling engines or body work, or when someone works on other people's cars there.4
That rule is aimed at a house that turns into a repair yard. A mobile visit is a different picture. The car belongs to the person who lives there, and the mechanic packs up and leaves.

The city is not the only one with a say, though.
- Apartments. Many leases ban car repair in the lot. Read yours, or ask the office, before the mechanic shows up.
- HOAs. Some covenants limit repairs that can be seen from the street. A brake job that takes an hour is rarely the issue. A car on stands for three days can be.
- Work lots. If the car is at your job, get the building's OK first.
Big jobs are where this matters most. A starter or a battery is quick. A transmission or an engine pull takes space and time, so plan where the car will sit.
Jobs That Need a Federal Card or a Certified Station
Air conditioning. This is the one rule that follows every mechanic in the country. The EPA says anyone who repairs or services a car AC system for pay must be trained and certified under Section 609 of the Clean Air Act by an EPA approved program.5 ASE is one of the approved programs on the EPA's list. If your AC needs a recharge or a leak fix, ask the mechanic about the card before the gauges come out.
Emissions tests. Cars registered in Albuquerque and Bernalillo County need emissions tests. That covers 1992 and newer vehicles under 10,001 pounds, hybrids included. Only certified Air Care stations may do the test. The county has more than 120 of them, and most charge about $30 plus tax.6
So a mobile mechanic can find and fix the reason a car failed, like a bad sensor or a check engine light. The test itself still happens at a station. If a car fails and comes back within 90 days, the city offers one free retest at its own headquarters.

Where the Old Oil Goes
A driveway is not a shop floor, so this question matters more with mobile repair. Albuquerque says anything poured into a gutter or storm drain, used motor oil and antifreeze included, flows straight to the Rio Grande, usually through the neighborhood arroyos. Stormwater gets no treatment on the way.7 The city says to take used oil to a collection site in a clean, sealed plastic container.
A careful mobile mechanic brings drip pans and mats, catches the fluid, and takes it with him. Before you book, ask one simple thing. What happens to the old oil and coolant? The right answer names a container and a drop off, not your trash can.
Your Warranty Survives a Driveway Repair
Some drivers think only the dealer can touch a car under warranty. The FTC says that is not true. It is illegal for a dealer to deny warranty coverage because someone else did the routine maintenance or repairs.8
Two catches come with that.
- Free warranty work. If the warranty pays for a repair, the dealer or maker can make you use a shop it picks.
- Records. The FTC says to keep records of oil changes and other service, because the warranty company may ask for them. Get a written invoice for every mobile visit and keep it with the car.
Shopping for a used car? Ask the seller for those same records, then book a pre purchase inspection before you pay.
Five Questions to Ask Before You Book
None of these take long. A real mobile business will not mind any of them.
| Ask | A good answer | Where to check it |
|---|---|---|
| What is the business name? | A real name you can look up | Secretary of State business search, city registration search |
| What will it cost before you start? | A price or a range after testing, before work begins | Get it in a text or in writing |
| Are you certified for AC work? | Yes, Section 609, if the job touches refrigerant | Ask to see the card |
| What happens to the old fluids? | Caught in pans and taken away | Watch the first drain |
| Will I get an invoice? | Yes, with parts and labor listed | Keep it for your warranty file |

Before You Book
- Is it legal to be a mobile mechanic in New Mexico?
- Yes. New Mexico has no state license for auto mechanics, so mobile repair is legal. Cities like Rio Rancho and Albuquerque still expect businesses to register or hold a city business license, and federal rules cover paid AC work.
- Do mechanics need a license in New Mexico?
- Not from the state. The New Mexico Regulation and Licensing Department has no board for auto mechanics. AC work for pay needs an EPA Section 609 certification, and emissions tests in Bernalillo County happen only at certified Air Care stations.
- Can a mobile mechanic work on my car at my apartment?
- Often, but check your lease first. Many apartment leases ban car repair in the lot. Ask the office before you book, and tell the mechanic where the car will be parked.
- Will using a mobile mechanic void my car warranty?
- No. The FTC says it is illegal for a dealer to deny warranty coverage because someone else did your routine maintenance or repairs. Keep every invoice. Repairs the warranty pays for can still be sent to a shop the maker picks.
- Can a mobile mechanic recharge my car AC?
- Yes, if the tech is certified under Section 609 of the Clean Air Act. The EPA requires that certification for anyone who services a car AC system for pay. Ask about it before the work starts.
- Can a mobile mechanic do my emissions test in Albuquerque?
- No. Only certified Air Care stations may do emissions tests in Albuquerque and Bernalillo County. A mobile mechanic can find and fix the reason a car failed, and then you take it back to a station.
- How do I check if a mobile mechanic is a real business?
- Ask for the business name. Look it up on the New Mexico Secretary of State business search and the city's registration search. Then read the Google reviews and get the price before any work begins.
