The building codes comprise the applicable building regulations of the individual federal states. In Germany, building regulations are under the purview of the federal states. This results in different regulations in the individual federal states. The regulations on the construction of buildings are stipulated in the individual building codes of the federal states. These are largely based on a model building code. Given the common foundations, the regulation system of the state buildings codes is therefore largely identical.1
Significant subjects of regulation in the individual state building codes include:
In addition to substantive provision, there are also formal regulations on construction authorities, the approval process and the conditions for authorised construction administrators in the building codes. Most of the differences in the individual state building codes are also found in the administrative procedures.
The building regulations ultimately serve as a legal basis for municipal statutes, which contain, for example, municipal requirements for roof shapes and façade designs.3
Each state building code is supplemented by different ancillary laws and ordinances, which are a component of the building regulations.4
