Submit a preliminary building application

Before submitting a building application, a written decision on individual questions of the building project (preliminary building decision) can be requested with a preliminary building application. As an anticipated part of the building permit, a positive preliminary building decision is binding for the subsequent building permit procedure.

A preliminary building inquiry is usually useful if it is unclear whether a property can be built on at all according to the applicable building planning law. A preliminary building inquiry can save financial expenses, since not all the building documents required for a building permit are necessary. In addition, the preliminary building permit provides certainty about the buildability of a property at an early stage.

The application for a preliminary building permit must be submitted to the lower building supervisory authority. It must be accompanied by the documents required to assess the issues to be decided.

The preliminary building permit is valid for four years, unless it is limited to a shorter period. This period may be extended upon application, which must be received before the deadline expires.
