It is important to have a custom map for your own building. Each floor should have detailed custom maps designed for it. Remember that all buildings that go through any remodeling should have their building maps updated. Ideally, these maps should be posted throughout the building in specific areas so that, in case of any emergency, a person can leave the building quickly and safely. Another good use for these maps is to point people in the right direction. They do not have to be posted everywhere, as that could lead to a dangerous situation, but a few key people should hold these maps like the receptionist.
