§ 154.071 OPEN SPACES.
   The following requirements are intended to provide exceptions or qualify and supplement, as the case may be, the specific district regulations set forth in §§ 154.020 through 154.028:
   (A)   An open space or lot area required for an existing building or structure shall not be counted as open space for any other building or structure.
   (B)   Open eaves, cornices, window sills, and belt courses may project into any required yard distance not to exceed two feet. Open uncovered porches may project into a front or rear yard a distance not to exceed five feet. Fences, walls and hedges in residential districts may be erected in any required yard, or along the edge of any yard, provided that no fence, wall or hedge located in front of the front building line shall exceed three feet in height, and no other wall or fence shall exceed eight feet in height.
   (C)   Where the dedicated street right-of-way is less than 50 feet, the front yard depth shall be determined by measuring 50 feet back from the center line of the street easement.
   (D)   No dwelling shall be erected on a lot which does not abut on at least one street, at least 50 feet in width, for at least 35 feet. A street shall form the direct and primary means of ingress and egress for all dwelling units. Alleys, where they exist, shall form only a secondary means of ingress and egress. Accessory buildings which are not part of the main building may be built in the rear yard.
   (E)   No minimum lot sizes are prescribed for commercial and industrial uses. It is the intent of this chapter that lots of sufficient size be used by any business or industry to provide adequate parking, unloading and loading space required for operation of the enterprise.
   (F)   On any corner lot on which a front and side yard is required, no wall, fence, sign, structure or any plant growth which obstructs sight lines at elevations between two feet, six inches and six feet above any portion of the crown of the adjacent roadway shall be maintained in a triangle formed by measuring from the point of intersection of the front and exterior side lot lines a distance of 30 feet along the front and side lot lines and connecting the points so established to form a right triangle on the area of the lot adjacent to the street intersection, 15 feet along the back and side lot lines and connecting the points so established to form a right triangle on the area of the lot adjacent to the street and alley intersection, seven and one-half feet along the back lot lines and all driveways connecting the points so established to form a right triangle on the area of the lot adjacent to the alley and driveway intersections.
 
   (G)   No accessory building shall be constructed upon a lot until the construction of the main building has been actually commenced, and no accessory building shall be used unless the main building on the lot is also being used.
   (H)   Whenever one or more residential, institutional, commercial or industrial buildings are proposed to be located in a cluster or grouping which has different arrangement, orientation or other site planning variation from that of other building, structures or uses in the area or on adjacent properties, the architectural design, location, orientation, service and parking areas of such buildings shall be planned so as not to adversely affect the use of adjacent or other properties in the area, as determined by the Planning and Zoning Commission.
   (I)   An ornamental fence exceeding six feet in height shall have a ratio of solid portion to open portion not in excess of one to four.
