Group dwellings shall be at least 2,000 feet apart from each other and shall not be located on lots of fewer than 12,000 square feet nor on lots having fewer than 500 square feet for every sleeping room or for every two beds, whichever is greater. Such uses shall have side yards of not fewer 30 feet and shall not be approved unless plans prepared by an architect or engineer are submitted which clearly indicate that adequate light, ventilation and fireproofing are provided, and that the dwelling facility and its accommodations shall be functional and convenient with regard to the specific needs of the group to be housed in the facility. Group dwellings shall be approved only after Council has found that plans and programs for management of the group dwelling are adequate and appropriate to the population to be housed and that adequate provisions have been made to assure the safety and welfare of the residents of the facility and of the adjacent neighborhood, including parking. Continued operation shall be subject to monitoring by such review agency as may be established and appointed by Council.
