* Minimum multi-family unit capacity for most communities will be based on the 2020 housing stock and the applicable percentage for that municipality's community type. In some cases, the minimum unit capacity is derived from an extrapolation of the required minimum land area multiplied by the statutory minimum gross density of 15 dwelling units per acre. In cases where the required unit capacity from these two methods would exceed 25% of the community's housing stock, the required unit capacity has instead been capped at that 25% level.
** Minimum land area is 50 acres for all communities in the rapid transit, commuter rail and adjacent community types. There is no minimum land area requirement for adjacent small towns. Where 50 acres exceeds 1.5% of the developable land area in a town, a cap has been instituted that sets minimum land area to 1.5% of developable land area in the town.
*** Developable station area is derived by taking the area of a half-mile circle around an MBTA commuter rail station, rapid transit station, or ferry terminal and removing any areas comprised of excluded land.
