All owners are required to attach a civic number (street number) to their houses and other buildings. The number must be easily spotted: the height of the numbers of letters must not be less than 9 cm (3.5 inches) or greater than 20 cm (8 inches).
The civic number must at all times be visible from the public road. If the house or building is located 30 metres or less from the public road, the civic numbers must be installed on the façade of the house or building, on a letterbox, fence or wall, but never on a tree, rock or garbage bin.
If the house or building is located more than 30 metres from the public road, the civic number must be affixed onto a support placed or located on the edge of the public road. The support must not be a tree, a rock or a garbage bin.
