Prerequisites
- You want to build or modify a structure.
- You have a person with building permit authorization at your side. This could be an architect or a civil engineer, for example.
Documents required
The specific documents depend on the individual case. Depending on the type and scope of your application, different documents will be required from you. The responsible authority can inform you accordingly. You will also be informed accordingly when applying via the online service.
Please note
A complete building application is essential for the smooth running of the process. Only a person authorized to submit building plans (usually an architect or civil engineer) may submit an application.
When applying for a building permit, you can choose between the simplified procedure and the concentrated procedure. With the simplified procedure, it is your responsibility to obtain any additional permits required from other authorities. You are responsible for ensuring compliance with all legal aspects of building regulations and ancillary building law. If you want to have everything from a single source, you should choose the concentrated procedure.
If you have any doubts about the fundamental permitability of your construction project, you can have these clarified early on with a preliminary building permit. However, this only answers specific questions and does not replace the required building permit.
Advice outside of ongoing approval procedures is subject to a fee.
