Submit a preliminary building application

    Wenn Sie einzelne rechtliche Fragen zu Ihrem Bauvorhaben haben, können Sie diese vor dem Bauantrag mit einer Bauvoranfrage klären.

    Description

    Before submitting a building application, you can submit a preliminary building inquiry to the building authority to request a binding decision on individual issues to be examined in the building permit procedure and whether the intended project complies with public law regulations.

    The subject of a preliminary building inquiry can be all matters that are examined in the building permit procedure. A preliminary building inquiry is generally useful if individual questions about the building project are unclear or if it is to be clarified whether a property can be built on at all in accordance with the applicable building planning law. A preliminary building inquiry can save financial expenditure, as not all the documents required for a building permit are necessary and the scope of the examination is limited to the specific questions. In addition, the building owner receives certainty about the buildability of a property at an early stage.

    The preliminary decision is valid for 3 years and binds the building authorities for this period, provided that the content of the preliminary decision does not fundamentally deviate from the statements made. An extension of the preliminary decision is possible on application.

    Procedure

    You fill out the application digitally in the building portal or in analog form and submit it together with the required documents to the responsible building authority.
    The building authority will check your application and the documents.
    If all documents have been submitted and there are no legal obstacles, the building authority will issue you with a preliminary building permit.

    Deadlines

    Die Bauverwaltung ist für den Zeitraum gebunden, insoweit die inhaltlichen Aussagen im Vorbescheid nicht grundsätzlich abweichen. 

    Period of validity: 3 years (Eine Verlängerung ist auf Antrag möglich.)

    Processing time

    If the building project is subject to Section 65 HBO, the deadlines of the simplified approval procedure for the preliminary building permit also apply:
    3 months with the option of an extension of up to 2 months
    The preliminary building permit is deemed to have been granted if no decision has been made within this period.

    Costs

    The amount of the fee depends on the scope of the preliminary building application and can be up to 40 percent of the building inspection fee, with a minimum of €100. The fee is to be calculated according to the extent to which the building permit is anticipated by the preliminary decision. Half of the fee is offset against the final building inspection fee if and to the extent that the preliminary building decision has a binding effect in the building permit procedure.
