Preliminary building application

Before submitting a building application, a so-called preliminary decision can be applied for on individual issues of the building project.

An application for a preliminary decision can be used to obtain legally binding information on whether a plot of land can be built on (even before the intended purchase of such a plot). A positive preliminary decision binds the building supervisory authority for the duration of its validity (currently 3 years), i.e. it can then no longer reject a building project for reasons that were already to be examined in the preliminary decision procedure. A positive preliminary decision therefore provides legal certainty for the concrete planning of a building project.

A preliminary building application is always recommended if the building project differs greatly from the surrounding development or if binding information is only to be obtained on individual problematic points of a building project. The three-year period of validity of the preliminary building permit can be extended by up to one year under certain conditions upon application in text form.
