Bauantrags

Bauantrags is the formal application for a building permit in German-speaking countries, submitted to the local building authority (Bauamt). Its purpose is to obtain legal clearance to construct a new building, make substantial changes to an existing structure, or change the use of a building. The process ensures that plans comply with land-use plans, building codes, fire safety, energy efficiency, and environmental protections. A Bauantrag is typically required for new builds, extensions, structural alterations, or changes of use.

In Germany, the procedure is governed by the federal Baugesetzbuch (BauGB) and the state-level Landesbauordnungen (LBO). Local planning regulations may add further requirements. The term and process are similar in other German-speaking countries, though the specific rules differ. In Austria, a Baubewilligung is used, while in Switzerland a similar Baubewilligung process applies. The exact documents and timelines depend on the jurisdiction and project type.

Contents of a Bauantrag generally include: site plan, floor plans, elevations, cross-sections, structural calculations where needed, a description of the project, an energy certificate, and any required environmental, heritage, or fire-safety assessments. Plans may also require agreements with neighbors or approvals from other authorities (nature protection, monument protection, utilities).

Process and outcome: after submission, the building authority reviews the plans for compliance with planning and technical standards. There may be opportunities for public participation or objections. The decision results in a Baugenehmigung (permit) with possible conditions or a rejection. If necessary, the decision can be appealed or the plans revised. Upon completion, a Bauabnahme (construction inspection) is conducted, and the use of the building is officially permitted.
