Numbers on all structures on the east side of streets extending north and south, and on all structures on the north side of streets extending east and west, shall be odd numbers commencing with the number 101; and numbers on all structures on the west side of streets extending north and south, and on all structures on the south side of streets extending east and west, shall be even numbers commencing with the number 100.

Main Street in the City of Jefferson shall be the base line for commencing to number all streets extending east and west; and Union Street shall be the base line for commencing to number all streets extending north and south.

The numbering shall be fixed by blocks, and in cases where the properties are not platted in blocks, the confines of a block shall be fixed by the council.

Each block shall be allowed 100 numbers with 50 numbers to each side of a street in the block. The numbers shall be assigned to structures on a frontage basis proportionate to the length of the block, and in the event a question arises as to the proper number for a particular structure, the question shall be decided by the city recorder.

It shall be the duty of every person owning, occupying or controlling any structure within the City to obtain from the city recorder the correct number for such structure and to number the same in accordance with provisions hereof, the same to be done within 90 days after the passage of the Development Code, or upon obtaining a building permit for the erection of any structure which may be constructed after passage of the Development Code.

Pursuant to such system the numbers shall be placed on the front of each structure as near the main entrance as possible, in such manners as to be easily seen and read from the public ways, and in accordance with the map and plan now on file in the office of the city recorder, which shall be known as the official numbering map of the City of Jefferson.

All numbers shall be not less than two and one-half inches in height for the number proper, and shall be distinctly legible.

It is unlawful for any person to fail or refuse to obtain a number or to place the same on any structure owned, occupied or controlled by such person, in the manner provided by this chapter; and it shall likewise be unlawful for any person to remove, alter or deface any number or to substitute any other number thereof. Any such act constitutes a violation of the Development Code and may be addressed as provided in Chapter 12.10.
