House number assignment

House numbers are assigned by the municipalities on the basis of building applications, notifications of construction measures or at the request of the owners. Street names and house numbers are used for orientation in the urban or municipal area and fulfil an organisational function for all personal or location-related data.

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

The local authorities are responsible for checking whether a house number has been affixed by the owner of the property/house. The local house number signage is also checked in the event of complaints. The property owner is then requested to ensure that the house number is visible from the road.

Two equivalent systems are used for the arrangement of house numbers: the so-called Paris system with a kind of zip system (the numbering starts at the end of the street facing the city centre with 1 on the left-hand side and 2 on the right-hand side and then runs separately according to even and odd to the other end of the street, whereby it often happens due to the different size of the individual properties, Due to the different size of the individual properties, it often happens that numerically adjacent numbers are not opposite each other in reality) as well as the so-called Berlin system with circulating house numbering (the numbering sequence starts with 1 on one side of the street, continues without interruption to the end of the street and then runs back on the other side of the street).
