A. 
Generally. No land or structure within the City, in any district whatsoever, shall be used for a group residence, so-called, in which five or more persons unrelated by blood, marriage or adoption are housed and live together as a family, except those who are members of a religious organization, order, diocese or religious community.
B. 
Special permit. In a specific case, the Zoning Board of Appeals, acting as the special Board of Appeals, may, after a public hearing, grant a special permit for the use of a structure and land for a group residence, provided there is no other group residence within 350 feet of the proposed site, and that such use will not be detrimental to the public good and will not adversely affect the value or amenity of neighboring property.
