1248.05  YARD REQUIREMENTS AND OPEN SPACE.
   (a)   Yard requirements shall be as set forth under each zoning district. Front, side, and rear yards shall be provided in accordance with the regulations hereinafter indicated and shall be unobstructed from the ground level to the sky, except by natural vegetation, permitted fences, and as allowed in Section 1268.05.
   (b)   All accessory buildings which are attached to principal buildings (e.g., attached garages) shall comply with the yard requirements of the principal building.
   (c)   In single-family residential developments containing five or more lots, the yard requirements may be waived in order to encourage innovative design and to provide for such housing types as the atrium or patio house. Such waiver may be obtained only by conditional use permit, as provided within each Residential District.
   (d)   For each multiple-family structure designed, used or occupied, containing at least twenty residential dwelling units or 18,000 square feet of gross floor area, whichever is less, there shall be provided a minimum of twenty percent of the area of the zoning lot for unobstructed open space which shall be located on the ground, but shall not include required yard spaces, or space provided for off-street parking.
   (e)   Upon approval of the Village Council, as evidenced by acceptance of the subdivision plat, a developer shall be allowed to satisfy yard requirements by establishing "average" setbacks and varying front yards. However, in such instances, the average setbacks or yards shall be at least equal to the minimum prescribed for that district, and the shortest setbacks or yards shall be consistent with public safety and health.
