A. The building official shall number all houses or buildings upon the streets of the city according to the house numbering system in use.

B. It is unlawful for any person to erect a house or building without numbering such house or building with the number designated by the building official, or for the occupant of any house or building, or for the owner or agent of any unoccupied habitable house or building to fail for a longer period than 10 days after notice from the building official so to do, to number such house or building with the number designated by him. When such number has been designated by the building official, the owner or occupant of such house or building shall cause a painted, carved, or cast duplicate of such number at least four inches in height and of a shade in contrast to the background upon which the number is mounted, to be placed in a conspicuous position upon the street side of such house or buildings, in a permanent, stationary and durable manner, unobstructed at all times by vines, screens, or anything that would tend to hide or obscure the number, and so that the number will be clearly perceptible from a distance of 150 feet.

C. It is unlawful for any person to number any house or building in any manner other than that prescribed in this section. [Code 2000 § 18-1-2].
