SECTION 120:10-3-20. Single Family Residential District (RD-1)

(a)   General Description. Single Family Residential District (RD1) is the most restrictive residential district. The principal use of land is reserved for single-family dwellings. However, related uses are appropriate in the district in order that a suitable environment is preserved for family life by permitting neighborhood uses, such as churches, schools, and certain cultural and recreational facilities. This district is intended to preserve and stabilize those neighborhoods which are basically single-family by allowing for two family conversions under specified conditions whereby existing neighborhood development scales are maintained. The area is intended to be protected from inharmonious functions that are inappropriate to the residential environment. Internal stability, attractiveness, order, and efficiency are encouraged by preserving openness of the living areas and avoidance of overcrowding by requiring minimum yards, open spaces, lot areas, by limiting the bulk of structures and through consideration of the proper functional relationship of each element of the district.

(b)   Uses Permitted. Property and buildings in an RD-1, Single Family Residential District, shall be used only for the following purposes:

(1)   Single-family detached dwelling.

(2)   Church.
