Zoning
RM-1
Residential, Mixed Districts, Low Density District
These Districts contain a mixture of the dwelling types found in RH Districts, but in addition have a significant number of apartment buildings that broaden the range of unit sizes and the variety of structures. A pattern of 25 ft to 35 ft building widths is retained, however, and structures rarely exceed 40 feet in height. The overall density of units remains low, buildings are moderately scaled and segmented, and units or groups of units have separate entrances. Outdoor space tends to be available at ground and upper levels regardless of the age and form of structures. Shopping facilities and transit lines may be found within a short distance of these districts. Nonresidential uses are often present to provide for the needs of residents.
