Arlington is compliant with the MBTA Communities Act. Town Meeting adopted the MBTA Communities Overlay District in October 2023, allowing multifamily housing by right in designated districts, and the state approved it in 2024. The state required Arlington to zone for a capacity of 2,046 units. For owners and investors, it can expand what you are allowed to build on an Arlington parcel.
Arlington meets the MBTA Communities Act through its MBTA Communities Overlay District, which Special Town Meeting adopted on October 25, 2023 as Article 12 of the zoning bylaw, and which the state's Executive Office of Housing and Livable Communities approved in 2024. As an adjacent community, Arlington was required to zone for a capacity of 2,046 multifamily units, about 10 percent of its housing stock. The overlay creates multifamily housing districts where multifamily is allowed by right, meaning qualifying projects no longer need a special permit.
The overlay applies to districts the town mapped, concentrated primarily along Arlington's commercial corridors, including Massachusetts Avenue and Broadway, and in its business areas. Arlington adopted a specific parcel list when it passed the bylaw, so whether a given lot is in the overlay is a parcel by parcel question. The only reliable way to know is to check the address against the town's adopted overlay map and parcel list. Send us the address and we will look it up.
Inside the overlay, multifamily housing is allowed by right at a minimum density of 15 units per acre, a meaningful change from Arlington's traditionally restrictive zoning. That can turn a parcel that previously allowed only a single home or a two family, or required a special permit for housing, into one where a multifamily building is permitted as of right. The exact unit count depends on the lot and the district rules, so each parcel needs its own analysis.
If your parcel sits in the overlay, your development potential, and therefore your value, may be higher than the old zoning implied. What that means depends on who you are:
We run that analysis before clients buy, sell, or hold.

ARLINGTON MBTA SECTION 3A
A free overlay and value check for Arlington owners and investors
Arlington's MBTA Communities Overlay District allows multifamily by right along corridors like Massachusetts Avenue and Broadway, and many parcels now carry development potential they did not have before. Send us your Arlington address and we will tell you whether it sits in the overlay, what it allows, and what that does to its value.
Yes. Town Meeting adopted the MBTA Communities Overlay District in October 2023, and the state approved it in 2024.
Arlington was required to zone for a capacity of 2,046 multifamily units, about 10 percent of its housing stock, the obligation for an adjacent community.
No. It allows multifamily by right only in the mapped overlay districts, and it permits housing rather than requiring it to be built.
Check the town's adopted MBTA Communities Overlay map and parcel list, or send us the address and we will confirm it.
It can, because by right multifamily potential adds development options a parcel did not have before. The effect depends on the specific lot.
