How to Start a Diesel Repair Shop
Opening a diesel repair shop is a bigger commitment than starting a mobile operation. You are choosing a building, a location and a crew, and those choices shape the business for years. This guide covers the main decisions in order, how to get the first customers through the door, and how to tell when a second location makes sense.

Choose the location for trucks, not for you
The best diesel shop locations are easy for a loaded tractor-trailer to reach and turn around in. Look for:
- Quick access from an interstate or major truck route.
- Room to park and maneuver full-length combinations.
- Nearby freight generators: distribution centers, terminals, industrial parks, ports or farms.
- Zoning that allows heavy vehicle repair.
- Distance from existing shops, or a gap in the services they offer.
Check All Roadside area pages for your target town to see which services are already listed nearby and which are missing. A town with plenty of general repair but no one listed for aftertreatment or trailer work may be an opening.
Size the building and bays
Think about door height and width, bay length for a tractor and trailer, pits or lifts, floor strength, ventilation, lighting, air lines, and space for parts and an office. Many shops start with fewer bays than the building allows and grow into it.
Equipment
Plan for lifts or pits, jacks and stands, air compressors, diagnostic hardware and software for the makes you will service, specialty tools, a parts washer, fluid handling and waste storage. Buy what your first services need, and add equipment as you add services.
Licenses, insurance and setup
- Register the business and get an employer identification number.
- Check state and local business licenses, environmental permits and fire codes.
- Talk with a commercial insurance agent about general liability, garage keepers, property, workers compensation and any service truck coverage.
- Prepare a W-9 and an invoice template, because fleets will ask for both.
Staffing
Hire for the work you plan to do first. A small shop might open with the owner, one or two technicians and someone handling the phone and invoices. See hiring diesel technicians.
Before opening day: set up your All Roadside listing with the services you will offer and your real hours. A shop listing covers its home town plus 25 miles. Add your shop free.
Get the first customers
- Breakdown calls. Drivers and dispatchers searching for help near your location land on All Roadside city, interstate, exit and problem pages and call from the directory. A listing puts you in front of them immediately.
- Google Business Profile. Create it with the right category and real hours as soon as the address is final.
- Local fleets. Visit nearby carriers and businesses with trucks. Bring a one-page sheet with services, rates and hours.
- Neighbors. Tire shops, parts stores, truck stops and towing companies refer work. Introduce yourself.
Set rates from day one
Build your labor rate from real costs, not from what the shop down the road charges. See setting a diesel shop labor rate.
When to open a second location
A second location can double reach, but it also doubles overhead and splits your attention. Signs it may be time:
- You regularly turn away work because bays are full.
- A steady share of calls come from a town outside your current area.
- You have a lead technician who could run a location.
- A fleet customer needs coverage in another town and will commit to work there.
Test demand before signing a lease. On All Roadside, a shop listing covers its home town plus 25 miles. Adding a mobile service truck or a second listing in the new town can show whether calls come from there before you commit to a building.
Frequently asked questions
How do I choose a location?
Look for access to major truck routes, enough room for trucks to maneuver, proper zoning and nearby fleets. Being near an interstate exit helps breakdown calls find you.
When should I open a second location?
When the first location is consistently full and well managed. Add a separate All Roadside listing for the new town so it appears on that area's pages.
