Preliminary building permit

With a preliminary decision, individual questions about planned construction projects can be clarified with the lower building supervisory authority before the start of a building permit procedure.

Before submitting a building application, you can ask for information in advance with a preliminary building inquiry on questions that would otherwise have to be clarified in the later building permit procedure.

A preliminary building request (application for a preliminary ruling) can be useful if it is unclear whether a plot of land can be built on at all under the applicable building planning law. A preliminary building request can save financial expenses, as not all documents required for a building permit are necessary. In addition, the client receives early certainty about the buildability of a plot.

In addition to the application form, the following documents must be submitted

  • Site plan or excerpt from the floor map,
  • Description of the project and
  • the building templates necessary for the assessment of the question asked

Building application (preliminary decision) form


The questions must be accessible to an independent assessment.


If the question in the preliminary ruling concerns a building, the involvement of a person entitled to a building proposal (architect, civil engineer) may be required.
