Except as hereinafter specified, no building, structure, or similar object, whether principal, accessory, temporary or permanent, shall be erected, placed, converted, enlarged, reconstructed, moved, or structurally altered, nor shall any building or land be used, which does not comply with all of the regulations of this Zoning Ordinance, and any other applicable City regulations nor shall any project begin before a zoning permit has been approved by the City.

The lawful use of a building of land existing on the effective date of this Chapter may be continued, unless otherwise noted, although such use does not conform to the provisions hereof. If no structural alterations are made the non-conforming use of the building may be changed to another non-conforming use of the same, or of a more restricted classification. Whenever a non-conforming use has been changed to a more restricted use, or a conforming use such use shall not thereafter be changed to a less restricted use. The non-conforming use of a building may be hereafter extended throughout those parts of a building that were manifestly arranged or designed for such use at the enactment of this Chapter.

No premises, building or portion thereof, used in whole or part for non-conforming purposes according to the provisions of this Chapter, which hereafter become and remain vacant for a continuous period of two (2) calendar years shall again be used except in conformity with the regulations of the district in which such building or premises is situated.

No building which has been damaged by fire, explosion, act of God, or the public enemy, to the extent of more than fifty percent (50%) of the fair market value of the building immediately prior to the damage, shall be restored except in conformity with the regulations of the Chapter. If a building is damaged by less than fifty percent (50%) of the fair market value, it may be repaired or reconstructed, and used as before the time of the damage, provided that such repairs and reconstruction be done within six (6) months of the date of such damage.

No accessory building shall be erected in any required court, or in any yard other than a rear yard except as provided hereinafter. Accessory buildings shall be at least three (3) feet from lot lines of adjoining lots which are in any "O-P", "R-1," or "R-2" District; on a corner lot they shall conform to the setback regulations on the side street; there shall be at least five (5) feet from any other separate building or structure on the same lot, and at least five (5) feet from any alley line, except that when any entrance to an accessory building faces the alley, said accessory building shall be at least twenty (20) feet from any alley line. Accessory buildings may be erected as part of the principal building or may be connected thereto by a breeze-way or similar structure, and such accessory building shall be considered as part of the principal building for all yard requirements. A carport or garage for a residence may be in a side yard provided that a full required side yard is provided between the garage or carport and the side lot line. An accessory building within fifty (50) feet of the front lot line shall have a full side yard between it and the side lot line. Accessory buildings which are not a part of the main building shall not be more than fifteen (15) feet in height; however, this regulation shall not be interpreted to prohibit the construction of a five hundred fifty (550) square foot garage on a minimum rear yard.

In any "O-P," "R-1," or "R-2" District there shall be a minimum front yard required as stated in the yard requirements for that particular district; provided that in no case shall the front yard depth be less than the smallest front yard depth of an existing building within two hundred (200) feet of either side lot line.

No lot shall be reduced in size so as to make the width or total area of the lot, or any yard or any other open space, less than the minimum required by this Chapter. No part of a yard, or other open space provided about a building or structure for the purpose of complying with the provisions of this Chapter, shall be included as part of a yard or other open space required under this Chapter for another building or structure.

Off-street parking and loading areas may occupy all or part of any required yard or open space, except as otherwise specified in this Chapter.

Whenever the plat of a land subdivision approved by the Planning and Zoning Commission and on record in the office of the County Recorder shows a set-back building line along any frontage for the purpose of creating a front or side yard line, the building line thus shown shall apply along such frontage in place of any other yard line required in this Chapter, unless specific yard requirements in this Chapter require a greater set-back.

All stand-alone dwelling buildings must have a minimum of one thousand one hundred (1,100) square foot living area.

Recreational vehicles are permitted to be inhabited in any district for a period of no more than seven (7) days in any six-month period. Occupied recreational vehicles are permitted at all times in approved trailer parks, but not manufactured home parks, except if unoccupied for storage purposes. Storage of a single uninhabited recreational vehicle owned by the occupant of the property shall be considered a conditional use. In granting such use the Commission shall consider how the recreational vehicle will be stored but shall not permit storage in front of the front plane of the house or on any public street.
