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 applied for 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 application is generally useful if it is unclear whether a property can be built on at all under the applicable building planning law. A preliminary building inquiry can save financial expenditure, as not all of the building documents required for planning permission 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 municipal administration or association municipal administration. 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 issued for a shorter period. This period can be extended upon application, which must be received before the deadline expires.
