(A) This is a residential district to provide for medium and high population density. The principal use of land may range from single-family to multiple-family dwelling units, including duplex and four-plex units and one-family row dwelling (party wall) with not more than six dwellings in a row or building.
(B) Certain uses are permitted which are more compatible functionally with intensive residential uses than with commercial uses. The recreational, religious and educational facilities normally required to provide an orderly and attractive residential area are included. Internal stability, attractiveness, order and efficiency are encouraged by providing for adequate light, air and open space for dwellings and related facilities and through consideration of the proper functional relationship of each use permitted in the district.
