Converting a campervan in Germany: modifications, inspection and documents
Germany · Vehicles converted or registered in Germany
Spanish vehicle-modification rules and ITV inspections do not replace German procedures. This guide helps you prepare a project; the competent authority and authorised technical service determine what your particular vehicle requires.
What to check in Germany
Section 19 StVZO governs the validity of the vehicle’s operating approval (Betriebserlaubnis) after modifications. Certain changes, including changes to vehicle class or those that may affect safety, can invalidate it. Parts and modifications do not all follow the same procedure.
Section 21 StVZO provides for individual vehicle approval and the relevant technical report where applicable. Before changing seats, structure, roof or installations, discuss your project with an authorised technical service and confirm the tests and documents required by the registration authority.
Questions to prepare before modifying your vehicle
- Which country and, where relevant, which state will handle registration?
- Will travel seats, anchorages, structure or vehicle classification change?
- What documents, inspections and checks does each installation require?
- How will weight, payload and the conversion affect insurance?
Keep drawings, component specifications, photos and supporting documents. Spaziou calculators help you plan; they do not certify an installation or authorise road use.
