   (B)   Footnotes for Table of Area and Height Regulations.
      (1)   Exception 1: The lot area for churches, public and private schools, or any permitted institution shall be a minimum of 20,000 square feet. Exception 2: No additional lot or parcel area is required for units above or below the ground (grade) floor, except as might be required to meet the parking space requirements of § 156.158.
      (2)   On all corner lots, the side requirement next to the interior lot shall be the same as an interior lot (ten feet), however, the setback from the intersecting streets shall be 25 feet in both directions irregardless of which street the building faces. Side yard to alley shall be a minimum of 20 feet on corner lots. No accessory building on a corner lot shall project beyond the front yard required on the adjacent rear lot, nor be located nearer than ten feet to the side line of the adjacent lots.
      (3)   Where a lot is used for any of the purposes permitted in this district and is located at the intersection of two or more streets, and where a Dwelling District adjoins the rear of the lot, the side yard on the side of the lot adjacent to the street shall not be less than ten feet in width, except that the buildable width of the lot shall not be reduced to less than 20 feet. In all other cases, a side yard is not required except on the side of a lot adjoining a Dwelling District, in which case there shall be a side yard of not less than ten feet.
      (4)   There shall be a minimum side yard of not less than 15 feet on both sides of the building or buildings, but where the property is adjacent to a Dwelling District, there shall be a side yard of not less than 25 feet on the side nearest to the residential lots. The parking of private automobiles may be permitted within the side yard areas, but not closer than six feet to any lot zoned for residential use.
      (5)   A rear yard of ten feet is required from an alley, except where a lot abuts on a Dwelling District, in which case there shall be a rear yard of not less than 25 feet, and no storage of materials or equipment, or the parking of automobiles shall take place within the ten feet closest to any residential lot or lots.
      (6)   These regulations apply only to buildings and structures other than mobile homes. Mobile homes on individual lots are subject to the regulations in § 156.119. Mobile homes in mobile home parks are subject to the regulations in § 156.118.
      (7)   The rear setback in Parkview Addition and part of Parkview 2nd Addition, described as Blocks 1-6 of Parkview Addition, per Plat recorded in Book 2, Page 24, on May 13, 1959; and Lots 1 and 12 of Block 7, of Parkview 2nd Addition, per plat recorded in Book 4, Page, on October 10, 1973, at the Douglas County Recorder’s Office, Douglas County, Illinois, shall be 20 feet.
