1258.07 YARD AND SETBACK REQUIREMENTS.
   (a)   Double Frontage Lots. Buildings on lots having frontage on two (2) non-intersecting streets need not have a rear yard, if any equivalent open space is provided on the lot. However, the applicable front setback shall be provided on both streets.
   (b)   Yards Abutting Alleys. In computing the depth of a rear setback or the width of a side setback, where the rear or side yard abuts an alley, one-half (1/2) of the width of the alley may be included as a portion of the required rear or side setback, as the case may be provided that no building, where a side or rear setback is required, shall be closer than three (3) feet to a side alley lot line or ten (10) feet to a rear alley lot line.
   (c)   Front Setback Modifications. In any single-family “R” District, where the average depth of at least two (2) existing front setbacks on lots immediately adjoining (or, if not immediately adjoining, within one hundred (100) feet of the lot in question and within the same block-front) is less or greater than the minimum front setback prescribed elsewhere in this Zoning Code, the required setback of such lot shall be modified. In such case, the setback shall not be less than the average depth of such existing front setbacks on the two (2) lots immediately adjoining (or, if not immediately adjoining, within one hundred (100) feet or, in the case of a corner lot, the depth of the front setback on the lot immediately adjoining) provided, however, that the front setback on any lot shall be at least thirty-five (35) feet and need not exceed one hundred (100) feet.
   (d)   Side Setback Modifications.
      (1)   Side setback may be varied where the side wall of a building is not parallel with the side lot line or is broken or otherwise irregular. In such a case, the average width of the side setback shall not be less than the otherwise required minimum side setback, provided, however, that such side setback shall not be narrower at any point than one-half (1/2) the otherwise required minimum side setback or narrower than ten (10) feet in any case.
      (2)   Side setbacks may be reduced by three (3) inches from the otherwise required minimum of each side setback for each foot by which a lot of record on March 1, 1961, is narrower than the lot width specified for the district in which the lot is located, where the building to be erected thereon is not higher than one and one-half (1-1/2) stories, provided, however, that no side setback shall be less than ten (10) feet in any “R” District, except as noted for “R-6" Multiple Residence District.
   (e)   Rear Setback Modifications. Rear setbacks in an “R” District may be reduced by six (6) inches from the required minimum for each foot by which a lot, on March 1, 1961, was less than one hundred fifty (150) feet deep in an R-1 Residence District and one hundred twenty (120) feet deep in an R-2 or R-3 Residence District (as of March 1, 1961), provided, however, that no rear setback shall be less than forty (40) feet in depth.
