(a) In a U-1 District, and on lots in U-4 Districts, the rear line of which adjoins a U-1 or U-2 District or on which a multiple-family dwelling is erected, every main and accessory building erected shall have a rear yard extending the full width of the lot. The least dimension of such rear yard for the main building shall be at least the sum of twenty percent of the depth of the lot plus one-half the height of the building. The least dimension of such rear yard for an accessory building shall be fifteen feet, except that the rear yard setback for an accessory building that has a wall greater than twenty-five feet in length facing an adjoining property, shall be increased by an additional one foot for every three feet of accessory building wall length greater than twenty-five feet. No accessory building shall be erected closer to any street line than the main building.
(b) In a U-2 District buildings and structures, including accessory structures, shall be setback from rear lot lines such distance as shall be approved by the Planning Commission as part of the site development plan approval based upon their massing, scale, level and hours of activity, noise and light generation, and similar factors, but in no case shall such rear setback be less than the height of the building or structure. The Planning Commission may require buffering of adjacent properties as it deems necessary to mitigate potential impacts from such factors. Buffers may include, but are not limited to, strips of land, mounding, fencing, and vegetative screening as determined by the Planning Commission.
(c) In a U-3 District, every building erected shall have a rear yard extending the full width of the lot. The least dimension of such rear yard shall be at least twenty percent of the depth of the lot and at least one-half the height of the building.
(d) The rear yards herein provided for shall be open for their full required dimensions from the ground, or other level permitted by this section, to the sky unobstructed, except for the ordinary projections of window sills, belt courses, cornices and other ornamental fixtures, or eaves, not more than two feet wide.
