Yards shall be related to the plan of the building as well as to a side or rear lot line. Buildings shall be arranged so as to assure visual and audible privacy between adjacent buildings and to avoid undue exposure to main streets or concentrated parking or loading facilities. An exterior wall containing the principal required windows of one or more habitable rooms shall be classified as a main wall, and other walls which may contain minor required windows of a habitable room, or windows of other rooms, shall be classified as end walls. Buildings shall be arranged so as to provide open yards, exclusive of driveways and parking areas as follows:
(a) Yards between a building and side or rear lot line shall be not less than, main wall to a lot line, one and one-quarter times the height of building, but not less than twenty feet, end wall to a lot line, one-half of building, but not less than ten feet.
(b) Yards between two buildings facing each other across an open space shall be not less than, main walls parallel or within thirty degrees of parallel, one and one- quarter times the total height of the opposing walls, and where walls overlap more than forty feet, the width of the yard shall be increased four inches for each additional foot that the walls overlap. An end wall shall be located from an opposing main wall not less than three-quarters of the total height of the walls. An end wall shall be located from an opposing end wall not less than one-half of the total height of the walls.
(c) Side and rear yards when adjacent to a U-1 or U-2 District shall be fenced by open ornamental fences or freestanding or retaining walls or hedges. Such fence, wall or hedge shall be subject to the approval of the Building Commissioner.
