In a housing development consisting of a group of separate buildings where such buildings do not all front upon a public street, and where such group is on a single lot or parcel of land twenty thousand (20,000) square feet or more in area under one (1) control, all buildings fronting upon a street or adjoining a street shall be set back from the street and from side street lot lines at least as much as would be required for front and side street yards on a separate lot. All buildings which adjoin a lot line which is the interior side lot line or rear lot line of adjoining premises shall conform to the provisions of Sections 357.08 and 357.09 which would apply on a separate lot. Every residence building in such a group shall be separated from any other building on the lot, except accessory buildings not used for residence purposes and not over fifteen (15) feet in height, by space not less in width than one-half (1/2) of the height of the adjacent wall of the higher building; except that where such space provides all required light and ventilation for any habitable room it shall not be less in width than two-thirds (2/3) such height. Where it provides all required light and ventilation for all the habitable rooms of any dwelling unit it shall not be less than such height but in no case less than forty-five (45) feet between one (1) story buildings, fifty (50) feet between two (2) story buildings, fifty-five (55) feet between three (3) story buildings and sixty (60) feet between buildings four (4) stories or more in height. Accessory buildings shall not be closer to any building not an accessory building than the height of the adjacent wall of such accessory building. Except as provided herein, no other front, side or rear yard regulations shall apply to residence buildings in such development. The Board of Zoning Appeals may modify the strict application of the requirements of this section in a specific case where it is demonstrated to the Board that the modification will provide light, air, ventilation and sunlight for all habitable rooms and open space for all occupants of a standard no lower than would be provided under such requirements.
