Urban area

from Wikipedia, the free encyclopedia

In German building planning law, an urban area is a building area which, in accordance with Section 6a of the Building Usage Ordinance (BauNVO), is used for living and accommodating commercial operations and social, cultural and other facilities that do not significantly disrupt residential use. In contrast to the mixed area , the mixed use does not have to be balanced.

The area category "urban area" was introduced into the building use ordinance in May 2017 in order to enable a higher structural density and a different mix of uses in urban locations than was possible with the previous categories such as the special residential area - also in response to the increasing demand for Housing in cities. The category corresponds to the “model of a city with short distances, local jobs and a good social mix”.

A special feature of the urban area is the unconditional possibility, explicitly provided for in the BauNVO, to determine different uses for individual floors. So it is possible that

  • Residential use on the ground floor on the street side is not permitted or is only permitted in exceptional cases,
  • only apartments are permitted above a floor specified in the development plan,
  • a proportion of the permitted floor area specified in the development plan or a size of the floor area specified in the development plan is to be used for apartments, or
  • a portion of the permitted floor area specified in the development plan or a size of the floor area specified in the development plan is to be used for commercial purposes.

In urban areas, a higher immission guide value of 63 dB (A ) applies during the day compared to 60 dB (A ) in core or mixed areas . This new area category had far-reaching consequences for immission control: The TA Lärm was adapted, but a change to DIN 18005 and other regulations would also be necessary. An editorial error was made, which was changed by a letter from the BMUB . Legal expert groups had already criticized the lack of coordination of the new type of building area with other regulations.

Permitted Uses

The following are generally permitted in the urban area:

  • Residential buildings
  • Business and office buildings
  • Retail establishments, pubs and restaurants as well as establishments in the accommodation trade
  • other commercial enterprises
  • Systems for administration as well as for church, cultural, social, health and sporting purposes.
