Gebäudeklasse

Gebäudeklasse is a regulatory classification used in German-speaking countries to categorize buildings for fire safety and related building code requirements. The term appears in Landesbauordnungen (state building codes) in Germany, as well as in Austrian and Swiss codes, though exact definitions and class ranges vary by jurisdiction. The system groups buildings into a small number of classes that reflect the expected fire risk, occupancy, and complexity of safety measures.

The criteria typically include building height, number of storeys, floor area, occupancy type (residential, educational, healthcare, industrial), fire load, construction type, and risk of ignition or spread. In general, higher classes correspond to greater protection requirements. The practical effect is that higher Gebäudeklassen trigger more stringent fire protection provisions, such as higher fire resistance ratings for structural elements, enhanced compartmentation, longer or more accessible escape routes, stricter limits on travel distances to exits, mandatory fire detection and alarm systems, automatic suppression where required, and greater access for firefighting.

Implementation and use: The classification informs planning, approval, and ongoing compliance processes and is often used in project descriptions and building permits. Since the exact thresholds are state-specific, developers and planners must consult the relevant Landesbauordnung or national equivalents for precise criteria.
