National legal terms


In Germany, the term is used in public building law . It is used both in the building regulations of the German federal states and in Section 29 of the Building Code . However, it is defined differently in the building regulations than in the building planning law of the building code. The term generally refers to objects that are comparatively immobile . This means objects that either cannot be moved without technical aids or remain in one place for comparatively long-term use.

In some building codes, the term is also legally defined. For example, Section 2, Paragraph 1, Clause 1 of the Lower Saxony Building Code defines structural systems as systems connected to the ground or resting on it and made from construction products. However, fixed fireplaces, advertising systems, bicycle parking systems, landfills and excavations or storage areas etc. can also be structural systems according to sentence 2 of the regulation, even if they do not fall under the definition in sentence 1. If a facility is a building structure within the meaning of building regulations, this means that its construction or modification usually requires a building permit .

In building planning law, on the other hand, a structural system is understood as a system that is artificially connected to the ground in a way that is intended to be permanent and that is relevant to land law.

"Structural structure" and " structure " are almost synonymous terms in terms of their content, " building " is a sub-term.


In Austria, a structure generally refers to “that which has been produced by a structural measure”. The term is referred to in all building laws / building regulations (of the federal states) and other building regulations.

The factual situation differs from the term building structure in that those are "structural systems which are connected to the ground when properly constructed and which require structural engineering knowledge." Structural system is the generic term and also includes small buildings that do not require a permit (such as Enclosures ), storage containers ( containers ) or technical systems that require a permit, structural revisions of the ground (such as retaining and lining walls in the area, landscaping measures and green spaces ) as well as those components that freely span the ground (such as cable cars or power lines). It represents the most general subject of building regulations.
