Where does a mailbox system have to be installed?
If the entrance to a building is from a public right-of-way (such as a pavement), the mailbox system is to be located near the entrance to the building. A special regulation from the Federal Ministry has defined that, when exchanging the old house mailbox system for a new one, the location previously used satisfies the requirements. if the building is not located on a public right-of-way, the mailbox system must be installed on the perimeter of the premises.
