Key points at a glance
- Kraftfahrzeugtechniker (motor vehicle technician) is a licensed trade (Anlage A no. 20 HwO). You need the master craftsman's certificate, an equivalent qualification, an Ausübungsberechtigung under § 7b HwO, an exemption or an employed master as works manager.
- Only inspection engineers or experts from a testing organisation may carry out the Hauptuntersuchung (HU, general inspection). Your workshop can serve as an inspection point (Prüfstützpunkt) if it has the equipment listed in Anlage VIIId StVZO.
- For the AU (emissions test) and safety inspections, the workshop needs recognition under Anlage VIIIc StVZO, usually granted by the Kfz-Innung (motor trade guild). Training must be repeated at least every 36 months.
- Manufacturers must give independent workshops repair and maintenance information. The motor vehicle block exemption regulation applies until 31 May 2028.
- For lifts, diagnostics, tyre and A/C service, many budget €50,000 to €130,000 (as of November 2026), plus the premises.

Who may run a car workshop
The Kraftfahrzeugtechniker trade is listed as no. 20 in Anlage A of the Handwerksordnung (Germany's Crafts Code). You may run it independently if you are entered in the Handwerksrolle, the register kept by the Handwerkskammer (chamber of skilled crafts). Bodywork and painting have trades of their own: Karosserie- und Fahrzeugbauer (vehicle body builder, no. 15) also requires a licence. Check with the chamber whether your services include accident repairs.
| Route | Requirement | Typical for |
|---|---|---|
| Meisterbrief (master craftsman's certificate) | Master's exam in the Kraftfahrzeugtechniker trade or a related trade | Mechatronics technicians with further training, often funded through Aufstiegs-BAföG |
| Equivalent qualification (§ 7(2) HwO) | Degree in vehicle engineering or state-certified technician with a matching focus | Engineers and technicians from industry |
| Ausübungsberechtigung (§ 7b HwO) | Journeyman's exam, six years of work experience, four of them in a senior role | Experienced workshop managers without a Meisterbrief |
| Ausnahmebewilligung (§ 8 HwO) | Equivalent knowledge, exceptional case | Individual cases |
| Employed works manager | A master actually works in the business | Business people or career changers as owners |
The building: planning law, waste water, waste oil
Setting up a workshop in a building that used to be a warehouse is a change of use and usually needs planning permission. Ask the local building authority whether car repairs are allowed in the area. In mixed areas with housing, expect conditions on opening hours and noise.
- Waste water: waste water containing mineral oil from the workshop and wash bay falls under Annex 49 of the Abwasserverordnung (Waste Water Ordinance). In practice that means a light liquid separator, regular servicing and records for the municipality.
- Storage: keep oils, coolant and brake fluid in drip trays or hazardous substance cabinets. Above certain quantities, the rules for installations handling substances hazardous to water apply.
- Waste oil: if you sell engine oil, you must take back the same quantity of used oil free of charge or name a nearby collection point. Dispose of it only through licensed waste oil collectors, with records.
- Painting: if you work with solvent-based paints, you must comply with emission rules. Many small workshops pass paint work to a partner.
HU and AU: what the workshop may and may not do
In Germany, the general inspection under § 29 StVZO (Road Traffic Licensing Regulations) is never carried out by the workshop itself but by a testing organisation: TÜV, DEKRA, GTÜ, KÜS or another approved body. You can still benefit from it.
Become an inspection point
Anlage VIIId StVZO provides for the Prüfstützpunkt: the testing organisation inspects vehicles at a workshop entered in the Handwerksrolle and uses its technical equipment. This includes a lift or pit, brake tester, headlamp aligner and exhaust gas analysers. You sign a contract with a testing organisation that offers fixed inspection days at your workshop.
Apply for AU recognition
Recognised car workshops may carry out the exhaust emissions test (AU) as part of the HU themselves. Recognition under Anlage VIIIc StVZO is granted by the responsible state body, which has usually delegated this to the local Kfz-Innung.
Meet the requirements
Entry in the Handwerksrolle, at least one responsible person with a master's exam, trained staff, test equipment under Anlage VIIId, liability insurance, a certificate of good conduct and a documented quality system.
Keep training up to date
Responsible persons and staff repeat the training no later than every 36 months. If you overrun the deadline by more than two months, you must take the initial training again.
Diagnostics and repair information
Modern vehicles need software for almost every repair: resetting the service, registering a battery, calibrating driver assistance systems. A multi-brand diagnostic tool covers a lot, but for deeper work you need the manufacturer portals. Regulation (EU) 2018/858 obliges manufacturers to provide repair and maintenance information to independent workshops, usually for a fee per hour, day or year.
- Security-related functions such as immobilisers and key programming are additionally protected. For these, the business and its staff need their own certification under the European SERMI scheme.
- Block exemption: the motor vehicle block exemption regulation (EU) No 461/2010 has been extended to 31 May 2028. It protects independent workshops' access to spare parts, tools and information. Servicing at an independent garage to the manufacturer's specifications generally does not put the manufacturer's warranty at risk.
- High voltage: for work on electric and hybrid vehicles, your staff need a high-voltage qualification. The levels are described in the DGUV guidance on qualifications for work on vehicles with high-voltage systems.
- A/C service: if you refill vehicle air conditioning, you need a refrigerant competence certificate.
Costs by level of fit-out
| Level | What is included | Range |
|---|---|---|
| Start | 2 lifts, multi-brand diagnostics, tools, compressor, oil extraction | around €30,000 – €55,000 |
| Service plus | plus tyre changer and balancer, A/C service unit, wheel alignment | around €50,000 – €90,000 |
| Inspection point and AU | plus brake tester, headlamp aligner, emissions testing, training | around €80,000 – €130,000 |
| Ongoing | Diagnostic licences, manufacturer portals, calibration, training | around €3,000 – €8,000 a year |
Used lifts and test benches are a good option if the inspection log and the latest expert inspection are available. Many founders take over an existing workshop with its customers. In that case, check permits, separator servicing and the lease carefully. What a website costs is covered in the guide to website costs. With us it is €1,800 one-off plus €30 a month for hosting.
Paperwork in the right order
- Advice meeting at the Handwerkskammer, entry in the Handwerksrolle
- Gewerbeanmeldung (trade registration) under § 14 GewO; for a GmbH or UG, entry in the Handelsregister (commercial register)
- Tax registration questionnaire via ELSTER, USt-IdNr. (VAT ID) for buying parts from other EU countries
- Registration with the Berufsgenossenschaft (statutory accident insurer) within one week of starting; for car workshops usually BGHM
- Business liability insurance covering damage to customers' vehicles in your care
- Building authority and lower water authority or municipality regarding use and separator
- Consider joining the Kfz-Innung: voluntary, but often the route to AU recognition and affordable training

Winning customers
An example from the Ruhr: two car mechatronics technicians, one of them a master, rent a former petrol station workshop. Tyre changes and A/C service carry the first months, and in the second half of the year two home care services with 22 vehicles between them come on board. Since a testing organisation started offering HU appointments at their workshop twice a week, the bays have been full.
- Transparent prices: fixed prices for servicing, front brakes or A/C service on your website build trust. What to watch out for is covered in the guide to advertising in Germany.
- Google profile: opening hours, HU days, services and photos of the workshop. More in the guide to the Google Business Profile.
- Reviews: ask for one when you hand back the keys, for example with a review QR code.
- Business customers: care services, trades businesses and couriers need quick appointments and one person to talk to.
