Zoning
R2
Two-Family District
The predominant use in R2 is a two-family dwelling or duplex. This district is generally served by local streets only and its neighborhoods are largely walkable and well established. It includes areas that are generally within walking distance of the stores and transportation facilities along Massachusetts Avenue and Broadway. The Town discourages uses that consume large amounts of land, uses that would detract from the single-family and two-family or duplex residential character of these neighborhoods, and uses that would otherwise interfere with the intent of this Bylaw.
Permitted uses

Agriculture
Housing-Group
Housing-Single unit
