It shall be the duty of the owner or occupant of every residence or
place of business within the village to have the same legibly numbered on
the front thereof, such numbers to be in accordance with the map adopted by
the Board for that purpose and filed with the Clerk, but nothing herein contained
shall require the numbering of an uncompleted house or building or of a vacant
lot. All buildings in the process of construction shall be so numbered within
10 days after they are ready for occupancy.
