How to start a mobile mechanic business that books its own repairs

A mobile mechanic sells something a shop can't: the repair happens where the car already sits. The driver skips the tow, the waiting room and the borrowed ride home. Turning that into a business takes more than a van full of tools. You need to know which jobs belong in a driveway and which belong on a lift, what your state expects before you take money for repairs, how to charge for a diagnosis that may end with "I'll think about it", and how to answer the phone while you're lying on a creeper. This guide covers the work, licensing and federal rules, insurance, the van, pricing, finding customers without renting leads, and how weather shapes the year.

We run service companies ourselves, and we wrote this from that side of the counter. It is general information, and none of it is legal, tax or insurance advice. Confirm every rule with the agency that enforces it where you work.

What work does a mobile mechanic business do?

Most mobile repair falls into five groups:

• No-starts and electrical. Batteries, starters, alternators, cables and fuses, plus the testing that tells one fault from another. Urgent, often same day, and usually the call that starts with a stranded driver.
• Brakes and wear items. Pads, rotors, calipers, belts, hoses, bulbs and sensors. Planned work that customers book for the office parking lot or the home driveway.
• Scheduled maintenance. Oil and filter, fluids, plugs, cabin and engine air filters, and the checks listed in the owner's manual schedule.
• Pre-purchase inspections. A buyer wants a used car looked over before paying a private seller or a small lot. Fixed scope, a written report and a hard deadline.
• Fleet maintenance. Vans, pickups and box trucks serviced in the owner's yard, often after hours, with a record kept for every unit.

Write down what you won't do on site as well. Clutches, transmissions, engine internals, alignments and anything that needs a lift or a full teardown usually belong in a shop. Pick a shop and a tow operator you trust and send those jobs their way. A written list prevents the worst outcome in this trade: a car in pieces in someone's driveway at dark, waiting on a part or a tool you don't have.

Does a mobile mechanic need a license or registration?

That depends on your state, and sometimes on your city. The SBA's licensing page ties the answer to two things, what the business does and where it operates, with licenses and permits possible at the state, county and city level. For auto repair, the rules we have read take a few shapes:

• Registering the repair business. California's Bureau of Automotive Repair requires a repair dealer registration for anyone who diagnoses, services or repairs vehicles for compensation, and its application page names mobile repair. Michigan's Department of State says a business that repairs, maintains or diagnoses motor vehicles for compensation must be registered with and licensed by the state.
• Certifying the mechanic. Michigan also certifies mechanics. Anyone repairing vehicles for compensation in a category of major repair must be certified, and certification comes from passing a state test in each category. A mechanic doing major repairs without it needs a trainee permit for those categories, and a trainee employed by a repair facility works under the direct supervision of a certified specialty or master mechanic.
• Local licenses and street rules. Cities and counties may license the business and limit where repairs happen. Baltimore's city code, for example, makes it unlawful for a motor vehicle repair service to repair, replace or adjust a vehicle or part on a public street or footway, with an exception for emergency repairs needed to move a broken-down vehicle safely.

Other states set their requirements differently, and the rules change, so we won't summarize them here. Our state-by-state startup pages cover formation and tax basics as a first stop. Then find your state's motor vehicle or consumer protection agency and look for repair facility or repair dealer registration, and ask your city or county clerk about business licenses and where repairs may be done. Get the answers in writing before you advertise. Apartment complexes, HOAs and office parks set their own rules too, so confirm permission with whoever manages the property before you book a job there.

Federal certification for AC work. Vehicle air conditioning carries a federal requirement in every state. EPA requires Section 609 certification before you repair or service a motor vehicle AC system for payment or barter, and the certification comes from an EPA-approved program's training and test. Its servicing requirements add three more pieces: refrigerant handling equipment certified by EPA or an EPA-approved testing organization, a one-time certification to your EPA Regional Office that you own approved equipment and that the people using it are trained and certified, and on-site records of each user's certification kept for three years. The same page notes that intentionally venting refrigerant is prohibited. If you aren't set up for all of that, leave AC off the service list.

ASE certification. The National Institute for Automotive Service Excellence says earning its certification takes a combination of hands-on work experience and a passing test, with renewal due every five years. Each test you pass is something concrete to list on your website and in a fleet proposal. It is separate from any state credential. Michigan's mechanic FAQ says ASE certification alone does not make you a state certified mechanic, though passed ASE tests may let you apply for state certification in certain categories without further testing.

Which federal rules apply once you start turning wrenches?

Brake and clutch dust. Once you have employees, OSHA's asbestos standard applies to brake and clutch work. 29 CFR 1910.1001(f)(3) requires employers to use engineering controls and work practices during brake and clutch inspection, disassembly, repair and assembly, such as a negative pressure enclosure with a HEPA vacuum, a low pressure wet cleaning method, or an equivalent method, and a simpler wet method is allowed in facilities that handle no more than five pairs of brakes or five clutches a week. EPA's brake and clutch guidance says you cannot tell by looking whether a part contains asbestos, and it warns against compressed air, brushes and dry rags for cleaning. In a driveway with kids and neighbors nearby, that guidance protects more people than you.

Used oil and fluids. EPA's used oil rules for businesses say to label every container and tank "Used Oil", keep them in good condition, and never mix used oil with anything else; storing it apart from solvents and chemicals is the only sure way to keep it from becoming hazardous waste. The same page describes puncturing and draining oil filters before recycling them as scrap metal, and notes that states can be stricter. Carry drain pans, lidded and labeled containers, absorbent and a spill kit, and find out where your area's recycler takes used oil, coolant and batteries before your first oil change.

What insurance and bonds does a mobile mechanic need?

Talk to an agent who writes auto repair businesses and ask each question below in writing. Our contractor insurance guide explains the policy types.

• General liability. The NAIC's small business guide says commercial general liability covers bodily injury, property damage, personal injury and false advertising claims. Ask how your policy would handle a fluid stain on a paver driveway, a customer tripping over your jack handle, and a repair that fails after you leave.
• The customer's car. Ask how damage to the vehicle itself is covered while it's in your care, including test drives. Agents may call this garagekeepers coverage; ask whether it applies when the car sits at the customer's home or workplace, since you never take it to a garage.
• Commercial auto. The same NAIC guide cautions that a personal auto policy on a vehicle you use for work may exclude business-related liability, so read its provisions closely. Our commercial auto guide covers how those policies work. Ask separately about tools and equipment stored in the van.
• Workers' compensation. Per the NAIC, employers in nearly every state must carry a workers' compensation policy for their employees. Your state's rules decide who counts and when coverage starts, so ask before your first hire.

Bonds come up only when a registration, permit or contract calls for one. Read your state's repair registration application and any fleet or public-agency contract for bond language before you sign anything. The surety bonds guide explains how they work and what they cost you when a claim is paid.

What equipment and vehicle does a mobile mechanic need?

Start with the vehicle. A van keeps tools locked and dry and gives you shelving; a pickup with a locking cap costs less and handles rougher lots. Whichever you pick, check its payload rating against the weight of tools, parts, fluids and full used oil containers. Our guide to buying a work truck walks through payload and upfitting.

• Lifting: a floor jack rated for the heaviest vehicles you'll book, jack stands, wheel chocks, a creeper or ground mat, and plywood pads for asphalt that softens in the heat.
• Diagnostics: a scan tool that reads live data, a digital multimeter, a battery and charging system tester, a test light and a jump pack.
• Tools: a cordless impact wrench with spare batteries, a torque wrench, sockets up to axle nut sizes, a breaker bar, pry bars and penetrating oil.
• Brakes: caliper tools, a bleeder kit, and wet cleaning supplies that fit the OSHA and EPA guidance above.
• Fluids: drain pans, funnels, a transfer pump, labeled containers with lids, absorbent and a spill kit.
• Site kit: work lights, a pop-up canopy, fender covers, floor mats for the customer's interior and trash bags.
• AC equipment only once you hold Section 609 certification and the equipment meets EPA's requirements.

What tools cost depends on the brand, where you buy and whether it's new or used, so collect current quotes rather than relying on an online list. Buy what this month's booked jobs need. Heavy-duty jacks for box trucks and specialty tools for one vehicle brand can wait until the work shows up on your calendar.

How should a mobile mechanic price jobs?

Build every price from your real cost of an hour: your pay, payroll costs if you have help, and overhead such as the van, insurance, tools, software and phones, spread across the hours customers actually pay for. The hourly rate calculator finds that floor. Then price each job in parts customers can follow:

Know your state's estimate rules before you quote. In California, the state's consumer guide to auto repair tells drivers that a shop must give a written estimate before doing any work, itemizing parts and the method of repair. Other states have their own versions, so build your estimate and approval steps around yours. Our guide to pricing mobile mechanic jobs works through the math with a hypothetical starter replacement.

How do you get your first mobile mechanic customers?

Urgent repair work goes to the first mechanic who picks up, gives an arrival time and says plainly if the repair can happen in that spot. Build the channels you own before you spend on anyone else's:

• A Google Business Profile listed as a service-area business, since you go to the car, with every repair you do entered as a service and photos from real jobs. Each setting a business with no storefront needs is in the guide to Business Profiles for contractors.
• A website with a page for no-starts, one per repair type, one for pre-purchase inspections and one for fleets, plus a booking form that asks for year, make, model, symptoms, where the car is parked and whether repairs are allowed there. That is how our websites for service businesses are built.
• A phone that gets answered under the car. An AI receptionist can ask the same intake questions, have the caller text a picture of the registration so you have the VIN, and book a time that allows for picking up parts.
• Referral partners. Tow operators get calls for cars that a new battery or starter could fix where they sit. Tire dealers, detailers, independent used-car sellers and repair shops with a full schedule all hear about work they can't take. Apartment and office property managers hear about breakdowns first.
• Local fleets. A company with a handful of service vans loses a working day every time one waits at a shop. Offer evening service in the company's own lot, with a record for each unit and one invoice a month.
• Past customers. A reminder when a car is due by date or mileage brings repeat work, sent only to customers who agreed to receive it. The texting rules guide explains consent.

Paid lead programs cover this trade too, on their terms. Google's Local Services Ads list automotive categories in the United States such as auto repair shop, brake shop, car battery store and auto air conditioning service. Google charges for each lead it counts as valid, and its own systems decide which charged leads earn a credit later. In August 2026 Google began moving these ads into Google Ads, starting with home service categories such as plumbing and HVAC, and says advertisers will still pay only for valid leads. If you buy leads to fill your first weeks, record each lead's cost next to the jobs it produced, and keep building the listing, site and customer list that never bill you per lead. The mobile mechanic industry page walks through the booking site, call answering and vehicle records we set up for mechanics who work on site.

What systems should be in place before the first call?

• A business phone number that texts back any caller you miss, so the driver knows a person saw the call. See business phone systems and the guide to missed-call text back.
• Vehicle-first records. VIN, engine, mileage at each visit, parts installed and photos, all attached to the car and its owner, so the next visit starts with the history.
• Estimates approved by text with a time stamp, plus a second approval when you find more work mid-job.
• Parts and core tracking on each job, so each old starter or alternator is returned for its core credit.
• Invoices with card payment collected in the driveway, and reminders sent by date or mileage.

Off-the-shelf field service software handles some of this. The custom CRM we build for mobile repair starts from the car: one record per vehicle, tied to its owner or fleet account.

How does the season change mobile repair work?

• Cold states: the government's fuel economy site, fueleconomy.gov, says battery performance falls in cold weather, which leaves the alternator working harder to keep the battery charged. Expect no-start calls to cluster on the first hard freezes. Ice, sleet and frozen ground also make some days unsafe for lying under a car, so keep a few planned jobs on the calendar that can slide to the next workable day.
• Hot states: summer brings AC work, which only a Section 609 certified tech should take, and midday heat that pushes jobs to early mornings and evenings.
• Snow states in spring: pothole season turns into brake, tire wear and suspension inspections as the weather warms.
• Everywhere: rain is the usual reason to move a driveway job. A canopy saves some days, and a customer who can offer a garage or a covered deck saves more.

Fleet maintenance evens out the swings, because company vans need service on a schedule whatever the weather. Sign fleet accounts in your slow months and fill the urgent calls around them.
