R-3 Mixed Residential District

The R-3 district is a multifamily residential district with gross densities between 15 and 40 dwelling units per acre, provided, however, that housing allowed in the R-1, R-1A, R-2A, and R-2D are a permitted use. It is intended primarily for multifamily and townhouse dwellings characterized by low-rise multistory buildings.  It allows a higher percentage of lot coverage than the R-2M zone, while also maintaining the residential living environment with landscaping, private/common open spaces, and other amenities for residents.  This district provides greater housing opportunities and efficient use of residential land near commercial, community activity centers, town centers, and areas well served by transit..
