🎯 The business: brakes, batteries, starters, belts, oil changes and check-engine diagnostics done in the customer’s driveway or office parking lot. People pay for not losing half a day at a shop. The skill is knowing which jobs belong in a driveway and which belong on a lift.

Is this for you?
It suits a working technician, or a serious hobby mechanic with real experience, who wants to keep the labor rate instead of the shop keeping it. Customers judge you on whether the car starts when you leave and whether the price matched the quote.
It is a poor fit if you have not done the common jobs many times. There is no lift, no parts runner and no senior tech to ask. It is also outdoor work, so heat, cold and rain are part of the job, and a wrong part means a second trip you cannot bill.
Who pays, and what
Busy parents, commuters who cannot spare a day without the car, older drivers, and people whose car will not start in their own driveway. Small fleets (landscapers, plumbers, delivery businesses) pay for regular maintenance in their own lot so their trucks never sit at a shop.
Most mobile mechanics charge a labor rate close to local shops, often $90 to $130 an hour based on published labor times, plus parts with a markup. A brake job on one axle commonly runs $300 to $550 with parts. A diagnostic visit of $100 to $150, credited toward the repair, filters out the people only looking for a free code read.
What it takes to start
| LLC, license, general liability and garagekeepers insurance (first payment) | $1,500 |
| Filling tool gaps: sockets, cordless impact guns, torque wrench, specialty pullers | $2,500 |
| Scan tool with live data and bidirectional tests | $800 |
| Low-profile floor jack, jack stands, wheel chocks, creeper, work lights | $600 |
| Drain pan, sealed used-oil and coolant containers, drip mats, spill kit | $400 |
| Website, cards, vehicle magnets | $300 |
| EPA Section 609 certification, if you will touch A/C | $55 |
| All-in | ≈ $6,155 |
This assumes you own a truck, van or SUV that can carry the tools and a mechanic’s tool set already. If you are starting with no tools, budget several thousand dollars more. An A/C recovery and recharge machine costs a few thousand dollars on its own; skip A/C work until the rest of the business pays for it.
Start to finish: the steps
1. Pick your job list. Write down the twenty jobs you can do in a driveway in under three hours with the tools you own. Brakes, batteries, alternators, starters, belts, spark plugs, sensors, oil changes, pre-purchase inspections and diagnostics are the usual core. Everything that needs a lift, a press or a clean room goes on the "refer out" list.
2. Check your state and city rules. Some states register auto repair businesses; California, for example, requires mobile repair businesses to register with the Bureau of Automotive Repair, with a separate registration for each repair vehicle. Then check your city’s rules on vehicle repair on residential property and streets. "Rules to check" below has the details.
3. Make it legal and insured. Form an LLC or start as a sole proprietor, get the city or county license, and open a business bank account. Buy general liability and garagekeepers coverage, which protects the customer’s car while it is in your care. See Choosing a legal structure and Business insurance.
4. Set up the waste side before the first job. Sealed, labeled containers for used oil and coolant, a drip mat under every car, and a spill kit in the truck. Find out where you will drop used oil, filters, coolant, old batteries and tires. Auto parts stores and county collection sites take some of these; a used-oil hauler takes larger amounts.
5. Open accounts with two parts stores. Ask for commercial pricing and delivery. A store that will run a part to the job site saves the trip that kills your afternoon.
6. Write a price sheet and a quote habit. Labor rate, diagnostic fee and whether it is credited, trip charge outside your area, and how you mark up parts. Quote every job in writing before you start, with the parts listed. See Pricing and margins.
7. Do ten jobs for reviews. Friends, neighbors and coworkers at a fair price in exchange for honest Google reviews with a photo of you at work. Set up a Google Business Profile as a service-area business before strangers look you up.
8. Win one or two small fleets. A landscaper with six trucks or a property manager with maintenance vans needs oil changes, brakes and inspections on a schedule. A monthly fleet visit fills weekdays and pays on invoice.
9. Add A/C and a second van later. Once you are booked out a week, consider Section 609 certification and an approved recovery machine, or a second technician on payroll with workers’ compensation. Each one should pay for itself within a season.
Pricing
| Labor rate (example) | $110 an hour, using published labor times |
| Diagnostic visit | $125, credited if you do the repair |
| Front brake pads and rotors | $350 to $550 with parts |
| Battery test and replacement | $60 to $90 labor plus the battery |
| Synthetic oil change at the driveway | $90 to $130 |
| Pre-purchase inspection | $125 to $200 |
| Parts | Cost plus 20 to 40 percent; customer-supplied parts at your discretion, no warranty |
These are example prices. Call three local shops and one mobile mechanic and ask what they charge for front brakes on a common car. Price near the middle and sell the convenience. Set a minimum charge so a ten-minute job still pays for the drive.
The math
A busy solo month: 20 working days with 5 billed labor hours a day is 100 hours. At $110 an hour that is $11,000 of labor. You also sell $5,000 of parts that cost you $3,700, so revenue is $16,000.
Costs for the month: parts $3,700, truck fuel and upkeep $900, phone and ads $500, insurance $350, shop supplies and waste disposal $300, and scan tool and repair data subscriptions $150. That is $5,900, leaving $10,100. Set aside about $800 a month for tool replacement and warranty comebacks and you clear about $9,300 before tax.
Five billed hours a day is a good day. Drive time, parts runs and quotes that do not turn into jobs all eat hours you cannot bill. Early months are often half this. Set aside a quarter to a third of what you clear for tax. See Small business taxes.
Getting customers
In rough order: a Google Business Profile with reviews and photos, Nextdoor and neighborhood groups, office parks where you can service several cars in one lot, small fleets, and realtors or used-car buyers who need pre-purchase inspections. Answer the phone or text back within minutes; people with a dead car call the next name on the list.
Lead apps and paid ads come after you know your close rate and what a customer is worth over a year. A good customer has two or three cars and calls you for all of them.
Running it week to week
Book by area so the day is not spent driving. Get the year, make, model, engine and VIN at booking so the right parts arrive. Confirm the parking spot: level, off the street, and with permission from the property owner. Lay the drip mat before you open the hood. Photograph the car before and after. At the end of each day, empty fluids into sealed containers and log what you dropped off and where. Once a week: invoices, parts returns and cores, and next week’s route.
Rules to check
Repair registration. Most states have no license for a general mechanic, but some register repair businesses. California requires anyone doing mobile auto repair for pay to register as an automotive repair dealer with the Bureau of Automotive Repair, with a separate registration for each vehicle used for repairs and the registration number shown on the vehicle and in ads. Check your state’s consumer affairs or motor vehicle agency. ASE certification is voluntary, but customers and fleets ask for it.
A/C work. Under Section 609 of the Clean Air Act, anyone who repairs or services a motor vehicle A/C system for pay must be trained and certified by an EPA-approved program and must use EPA-approved recovery equipment. Venting refrigerant is illegal. Certification is a short open-book test; MACS, one approved program, charged $55 in 2025 for a prep webinar and test.
Used oil and fluids. EPA’s used oil rules exempt people changing oil on their own personal vehicles. Paid work is a business, so the business rules apply: store used oil in containers in good condition, labeled "Used Oil", do not mix it with solvents or other waste, clean up spills, and send it to a collection center or a hauler. Some states, California among them, are stricter. Never let fluid reach a storm drain. Old batteries and tires have their own state recycling rules and fees.
Working at customers’ homes. Many cities restrict commercial vehicle repair in residential areas and on public streets, and many HOAs and apartment complexes ban it outright. Ask the customer to confirm the HOA or property manager allows it. Some cities want a home occupation permit if you store parts or park the work truck at home.
What goes wrong
A misdiagnosis: you replace the part and the light comes back. Charge for diagnosis and do it properly before quoting. A stripped bolt or a seized caliper turns a two-hour job into a tow to a shop; tell the customer up front that old cars can surprise you, and know a shop you can hand off to.
A spill on a customer’s new driveway, a car rolling off a jack, a scratched fender. Chock the wheels, use stands every time, and carry the insurance. The quiet business killer is underpricing parts trips and comebacks, so build them into the rate.
Questions people ask
How much does it cost to start a mobile mechanic business?
About $6,000 if you already own a suitable vehicle and a basic tool set: insurance, tool gaps, a good scan tool, jacks and stands, fluid containers and a little marketing. Starting with no tools costs several thousand dollars more.
Do you need a license to be a mobile mechanic?
In most states only a business license, but some states register auto repair businesses, and California requires mobile repair registration for each repair vehicle. A/C work needs EPA Section 609 certification everywhere in the U.S.
How much do mobile mechanics charge per hour?
Often $90 to $130 an hour, close to local shop rates, plus parts. Many also charge a diagnostic fee of $100 to $150 that is credited toward the repair.
Can a mobile mechanic work in an apartment parking lot?
Only with the property owner’s permission. Many complexes, HOAs and cities ban vehicle repair on their property or on the street. Ask the customer to confirm before you book.
How much can a mobile mechanic make?
A booked solo mechanic billing 100 labor hours a month at $110 can clear around $9,300 before tax, as worked above. New businesses usually make about half that while building reviews.
