Starting a mobile mechanic business comes down to four decisions: your legal entity, your state and city registrations, your insurance, and how you document work. Licensing is the part people get wrong, because there is no national rule. Some states require a license to turn a wrench for money and some require nothing at all.
Most of what is written on this topic states licensing rules as if they were the same everywhere. They are not, and the differences are large enough to matter to your bank account. The state facts below come from the states’ own statutes; where something was not verified, this article says so instead of guessing for you.
Two warnings. City and county rules sit on top of state rules, and that is where new operators get caught. And none of this is legal advice: it is a list of which questions to ask and who to ask.
The short version
- There is no federal mechanic license. Requirements are set by states, then again by cities and counties.
- How far apart states sit: Hawaii licenses the shop and the individual mechanic; California licenses through the Bureau of Automotive Repair and New York through the DMV; Texas has no state license for mechanical repair at all.
- Nevada requires a DMV garage registration: $25 plus a $5,000 bond.
- Texas does require keeping a record of each repair for one year (Occupations Code Ch. 2305), which almost nobody starting out knows.
- Insurance is not one policy. Price general liability, garagekeepers, commercial auto and tools coverage separately.
- Your first 30 days: entity, registrations, insurance, pricing, paperwork. Customers come after paperwork.
Step 1: pick your entity
Sole proprietor is the default if you do nothing. An LLC is the common choice for a one-van operation, for liability separation, and is worth an hour with an accountant since tax treatment and filing fees vary by state. An LLC does not replace insurance, and insurance does not replace an LLC. Then get an EIN and a business bank account that is not your personal checking, because mixing them loses the separation you just paid for.
Step 2: find out what your state actually requires
There is no national rule, and the spread is wide. Texas has no state license for mechanical repair at all. Hawaii licenses the repair dealer and the individual mechanic. California licenses through the Bureau of Automotive Repair, New York through the DMV, Nevada through a DMV garage registration at $25 plus a $5,000 bond, and Florida registers by employee count at $50, $150 or $300. Everything else changes at the state line, and we read 28 states’ own statutes to write it up separately: do you need a license to open an auto repair shop.
Texas has one wrinkle worth knowing before you get there. There is a registration for body shops (Occupations Code Ch. 2304, $50/year), and that registration was assigned to the TCEQ by a 2025 law, but the TCEQ’s own site returned nothing for the program. The statute is on the books; confirm the administrative program is running before relying on it.
Then check your city and county. This is the step that catches people. General business license, home occupation permit if you dispatch from your house, zoning on where a commercial van can park overnight, rules about repairs on a public street: all local. Call the city clerk. Fifteen minutes prevents a citation.
And check waste disposal rules. Used oil, filters, coolant and batteries have handling requirements, and you produce the same waste as a shop with none of the infrastructure. Ask your state environmental agency before your first oil change.
Step 3: know the estimate rules where you work
Even where no license is required, most states cap how far above a written estimate you can go, and the number changes at the state line: Massachusetts stops you at $10 over, Colorado at 10 percent or $25 whichever is less, and Texas and Arizona have no rule at all. The whole list is in auto repair estimate laws by state.
Two things that matter specifically to a mobile operator. Work near a state line and you are under two rulebooks for the same job done the same way. And Nevada and Hawaii require a posted consumer rights sign at a specific size, while Washington prescribes the exact wording down to a 1.5-inch first line: all written for a fixed location, so if you operate mobile in those states, ask the agency how it applies to you.
Step 4: price your insurance before you price your labor
Insurance is not one policy, and any article giving you a single dollar figure is making it up. Rates depend on your state, driving record, van, revenue, and what you touch. Get three quotes from agents who write commercial auto and garage risks, and ask about these by name:
- General liability, for third-party injury and property damage
- Garagekeepers legal liability, for damage to a customer’s vehicle in your care. General liability does not cover it, and it is the one that ends businesses.
- Commercial auto on the van. Your personal policy does not cover a vehicle used for business, and learning that at claim time is a catastrophe.
- Tools and equipment, separate from the van policy. Your scan tool alone justifies the conversation.
- Workers’ comp, required in most states the moment you have an employee.
Ask every agent one question: does this cover me working on a customer’s vehicle at their home. Get it in writing.
Step 5: set up your paperwork before your first job
The step new operators skip, and the one that decides whether year two exists. Three documents and one record:
- An estimate approved before you drive out: the auto repair estimate template.
- A repair order written at the vehicle, not reconstructed later: the auto repair work order template.
- An invoice you hand over on the spot: the auto repair invoice template.
- Photos before you start, attached to the job. On a driveway you have no cameras and no witnesses.
Then retention. Texas requires keeping a record of each repair for one year, Hawaii for two, Washington and Nevada for one. Even where nothing is required, keep everything: your own history on a vehicle is what lets you quote a returning customer in thirty seconds.
Garage does all four in one place, plus VIN and license plate lookup against your own shop’s history, scheduling, and photo-based technical reports on Premium. Essential is $39/mo for one user, which is what a one-van operation is. Premium is $69/mo for up to seven.
Your first 30 days, realistically
Days 1 to 7. Entity, EIN, business bank account. Call the city and county and write down what they tell you. Start insurance quotes, which take longer than you think.
Days 8 to 14. Print your state’s estimate and record rules. Set your labor rate by working backward from what you need to earn and what drive time costs you, not from what the shop down the road charges: the effective labor rate calculator.
Days 15 to 21. Run the document set end to end on your own vehicle. Estimate, repair order, photos, invoice. Find the friction while nobody is standing next to you waiting.
Days 22 to 30. Take work. Google Business Profile, then ask every early customer for a review, worth more to a mobile operator than any paid channel: how to get more Google reviews.
The order matters. Everyone who puts customers ahead of paperwork rebuilds their records from memory later.
Frequently asked questions
Do I need a license to be a mobile mechanic?
It depends on the state, and then on the city. Hawaii licenses both shops and individual mechanics. California and New York license repair businesses. Texas has no state license for mechanical repair. States not listed here were not researched, so check your state’s own site and call your city clerk.
How much does mobile mechanic business insurance cost?
There is no honest single number. It varies by state, driving record, van, revenue, and the work you do. Get three quotes, and make sure garagekeepers liability and commercial auto are both included: a personal auto policy will not cover a work van.
Can I start a mobile mechanic business with no money?
Lean, yes. Zero, no. Insurance, registrations and the entity filing are real costs, and skipping insurance is not starting lean, it is gambling your house. What you can defer is a fully stocked van: start with the jobs your current tools cover.
Do I need an LLC to be a mobile mechanic?
Not legally, in most places. Many operators form one for liability separation, which is worth an hour with an accountant in your state. What an LLC does not do is replace insurance.
Bottom line
The licensing question does not have one answer, and anyone who gives you one has not checked. Verify your own state, call your own city, price insurance with an agent who understands garage risk. Then get the paperwork right before your first paying job, because the estimate, the repair order, the photos and the invoice are the whole difference between a business and a guy with tools.
