1137.07 YARD REQUIREMENTS.
   (a)   Except as hereinafter provided, no building or structure shall be erected unless such building or structure conforms, and no building or structure shall be altered, enlarged or reconstructed unless such alteration, enlargement or reconstruction conforms with the yard regulations of the district in which it is located, as follows:
      (1)   Front yard depth. The minimum front yard depths shall be as required in Tables 1 and 2.
      (2)   Front yards on a through lot. At each end of a through lot there shall be a front yard of the depth required by this section for the district in which each street frontage is located, and one of such front yards may serve as a required rear yard.
      (3)   Front yard between buildings. Where a lot is situated between two lots, each of which has an existing main building thereon, the front yard requirements of such lot shall be the average of the front yards of said existing buildings.
      (4)   Front yard adjoining building. Where a lot abuts only one lot having an existing main building thereon, the front yard requirement of such lot shall be the average of the front yard of the existing building and the required front yard.
      (5)   Side yard requirements. There shall be two side yards for each lot, the minimum width of each and the aggregate width of both shall be as required in Tables 1 and 2.
      (6)   Corner lot, side yard width to the side street line. In the case of a corner lot, the side yard width to the side street line shall be equal to the front yard depth requirement for the district in which the lot is located.
      (7)   Rear yard requirements. There shall be a rear lot for each lot, the minimum depth of which shall be as required in Tables 1 and 2.
      (8)   Rear yard accessory building. An accessory building not exceeding twenty (20) feet in height, may occupy not more than thirty percent (30%) of the required rear yard area, provided that no accessory building shall be closer than three feet to a side, or rear property line. In the case of a garage when the vehicle opens to an alley, the set back requirement must be a minimum of seventeen feet to prevent encroachment.
      (9)   Yard requirements for private swimming pools. A pool wall shall not be located any closer than six feet from a side or rear property line. Under no circumstance shall a private swimming pool be located in the required front yard. (Ord. 312. Passed 9-26-77; Ord. 381. Passed 2-25-80.)
   (b)   General Provisions and Exceptions to Yard Requirements.
      (1)   Yards Apply to Only One Building. No required yard or other open space around an existing building, or which is hereafter provided around any building for the purpose of complying with the provisions of this Zoning Ordinance shall be considered as providing a yard of open space for any other building; nor shall any yard or other required open space or any lot be considered as providing a yard or open space for another lot whereon a building is to be erected.
      (2)   Fences, Walls, and Hedges. Fences, walls and hedges, not to exceed seven feet in height, may be permitted in any required yard, or along the edge of any yard, provided that no fence, wall or hedge along the sides or front of any required front yard shall be over two and one-half feet in height. Provided, however, that nothing contained in this Zoning Ordinance shall be deemed to prohibit the construction or maintenance of a fence or any height in connection with any permitted agricultural use.
      (3)   Corner Visibility. No fence, wall, hedge or other planting or other obstruction to vision, extending in excess of two and one-half feet above the established street centerline grade shall be erected or maintained on that part of the corner lot that is included between the lines of intersecting streets and a line intersecting them at points of twenty-five feet distant from the intersection of the street lines. (Ord. 312. Passed 9-26-77.)
