In a housing development on a single lot or parcel of land 20,000 square feet or more in area under one control in any area district other than an AA or an A Area District, the required minimum lot area per dwelling unit may be calculated from the area of the entire development, in which area may be included community open spaces, parking spaces and drives other than public streets, which are within the same development parcel and accessible to all occupants of the parcel group, as well as the private yards accessible directly to individual buildings, but excluding any areas to be dedicated for public purposes. The premises of each dwelling house or row house in such housing development shall include a private yard having an aggregate net area per dwelling unit of not less than 800 square feet, which aggregate net area shall be exclusive of the space occupied by the main building and garage or parking space and shall be maintained as an independent yard area as provided in Section 355.03.
