RM1
Residential Multi-Dwelling 1 Zone
The RM1 zone is a low-scale multi-dwelling zone that is generally applied in locations intended to provide a transition in scale to single-dwelling residential areas, such as the edges of mixed-use centers and civic corridors, and along or near neighborhood corridors. Allowed housing is characterized by one to three story buildings that relate to the patterns of residential neighborhoods, but at a somewhat larger scale and building coverage than allowed in the single-dwelling zones. The major types of new development will be duplexes, triplexes, rowhouses, courtyard housing, small apartment buildings, and other relatively small-scale multi-dwelling and small-lot housing types that are compatible with the characteristics of Portland's residential neighborhoods.
