House number assignment

House numbers are assigned on the basis of building applications, notifications of construction measures or at the request of the owners by the municipalities. Street names and house numbers serve as orientation in the city or municipality and fulfil an ordering function for all personal or location-related data.

In order to be able to integrate new buildings into an existing house number sequence, it may be necessary to change existing house numbers.

It is the responsibility of the municipalities to check whether a house number has been affixed by the owner of the land/house. The local house number signage is also checked in case of complaints. The property owner is then requested to provide a house number visible from the traffic area.

For the arrangement of house numbers, 2 equivalent systems are used: the so-called Paris system with a kind of zipper system (the numbering starts at the inner end of the street on the left side with 1 and on the right side with 2 and then runs separately into straight and odd to the other end of the street, whereby it often happens due to the different sizes of the individual plots that numerically adjacent numbers are not opposite each other in reality) as well as the so-called Berlin system with circumferential house numbering (the number sequence begins on one side of the street with 1, continues without interruption to the end of the street and then back on the other side of the street).

To the municipal board or, in the case of cities, to the magistrate.
