Family care homes, convalescent care facilities and group homes, where permitted, are subject to the following conditions:
(a) General Provisions.
A convalescent care facility is permitted as a conditional use in the R-3 and BR-1 Residential Districts. Group homes are permitted as a conditional use in the R-3 and BR-1 Residential Districts. Family care homes are permitted as a conditional use in the R-1, R-2, R-3 and BR-1 Residential Districts.
(b) Dispersal.
(1) To prevent the creation of a de facto social service district, the Zoning Inspector in the case of permitted uses, and the Board of Building and Zoning Appeals in the case of conditional uses, shall exercise care that proposed homes and facilities do not violate the provisions of subsections (b)(2) and (3) hereof. These provisions are intended to assure that such homes and facilities do not exceed the limited capacity of a neighborhood's existing social structure to accommodate them. These provisions are also intended to avoid an overconcentration of such homes and facilities which may inadvertently create an institutional setting, and thus impede successful functioning of the homes and facilities.
(2) No more than a total of three homes or facilities shall be permitted on the same block face in a Single-Family Residential District. No more than a total of three family, convalescent care facilities or group homes shall be permitted on the same block face in a Multi-Family Residential District.
(3) No home or facility shall be permitted if it is shown that such home or facility would increase the number of persons living in such homes beyond thirty-two persons, living within a radius of one-fourth mile of the applicant.
(c) Home Appearance.
The outside appearance of a family care home, convalescent care facility or group home shall be designed and maintained to reflect a residential character within the neighborhood. There shall be no outside evidence of the residential nature of the home other than one sign not exceeding four inches by twelve inches, non- illuminated and mounted flat against the wall near the entrance door to the home, stating the owner's name.
