(A) Purpose. The purpose of this district is to maintain and promote medium to high density residential development as might be appropriate for garden apartments and condominiums, and at the same time to permit a variety of housing types. Population density and height of buildings are low enough to be generally compatible with single-family residential development in the same general neighborhood.
(B) Permitted uses. Within the A-3 district, a building or premise shall be used only for the following purposes:
(1) Any use, together with the conditions attached thereto, permitted in the A-1 district;
(2) Two-family dwellings, including accessory apartments, in accord with the provisions of § 152.089(B);
(3) Multi-family dwellings, including condominiums, apartments and related long term occupancy units;
(4) Rooming and boarding houses;
(5) Child day-care services;
(6) Hospitals, clinics and related uses, provided a 15-foot evergreen buffer is established whenever these uses abut residential uses and no building shall be established closer than 50 feet to the nearest property line. (The buffer may be counted as part of the required setback.);
(7) Townhouses, in accord with the provisions of § 152.099;
(8) Patio and zero lot line houses, in accord with the provisions of § 152.100;
(9) Group-occupied dwellings, provided the dwelling arrangements are reviewed and approved by the Planning Commission, following an advertised public notice and hearing on the occupancy request.
(C) Dimensional requirements. Regulations governing the location and height of structures, and the area upon which they may be placed are as follows:
(1) Lot area requirements.
(a) Single-family dwellings shall have a minimum of 5,000 square feet.
(b) Two-family dwellings shall have a minimum of 7,500 square feet.

2. The minimum depth for two-family dwellings shall be 7.5 feet.
3. The minimum depth for three- or more family dwellings shall be as follows. No building shall be erected closer than 7.5 feet from any side lot line. Where a building exceeds 80 feet horizontally and/or 35 feet vertically, whichever is greater, the side yard shall increase by the ratio of one foot for each additional seven feet in width and by the ratio of one foot for each additional three feet in height. On lots with two or more principal residential dwellings or uses, the minimum distance between the uses shall be not less than 15 feet.
