§ 157.020  LOTS AND YARDS.
   (A)   Unless a plat has been approved for a planned-development project, only one principal building and its permitted accessory structures may be erected on any lot of record.  Temporary structures are permitted during construction only.
   (B)   No part of a yard required for any building may be included as fulfilling the yard requirements for an adjacent building.
   (C)   Within the area defined by the intersection of any two right- of-way lines of streets or a street and railroad and a straight line intersecting those two right-of-way lines at points 30 feet from their intersection, no obstructions to vision between a height of 3-1/2 feet and ten feet above the imaginary plane defined by those three points of intersection shall be permitted.  This provision shall apply in all districts except B-1 Central Business Districts.  This regulation shall not be deemed to prohibit any necessary retaining wall.
   (D)   Double-frontage lots shall, on both of the adjacent streets, meet the front yard regulations of the district in which they are located.
   (E)   Corner lots shall meet the frontyard regulation on both the side facing the principal street, but a ten-foot reduction in the front yard regulation is permitted on the side facing the secondary street, provided the reduction does not result in a side yard less than that otherwise required by this chapter.
   (F)   No accessory buildings are permitted in front yards.  They are permitted in rear or side yards according to the dimension and area regulations contained in the appendix to this chapter.
