In 2021 the Massachusetts State Legislature passed the MBTA Communities act, which requires cities and towns served by the MBTA (aka “MBTA Communities”) to create districts where multi-family housing can be built by-right, without a disretionary approval process. The law was intended to help address the Commonwealth’s housing shortage, and to encourage more transit-oriented development. Building housing near transit and walkable areas has a lot of environmental benefits; it let’s people take trips without driving, lessens congestions, and cuts down on greenhouse gas emissions. It’s a solid strategey.

Arlington created its multi-family districts in the fall of 2023 and the Attorney General’s office approved them in June 2024. The laws have been on the books for just over a year — what kind of a difference are they making in Arlington?

2024 was a slow year for the MBTA Communities act in Arlington; there was one application which turned a two-family home on Belknap St into a pair of two-family homes, for a net change of two additional dwellings. 2025 has brought more activity. There are four applications under the review by the Arlington Redevelopment Board but none have been approved yet. These are:

  • 225 Broadway, to convert a two-family home into a four-family,
  • 126 Broadway, to convert a two-family home into a mixed use building with space for a business on the first floor, and 14 apartments,
  • 18 Grafton, to convert a one-family home into a four-family, and
  • 9-11 Robbins Road to convert a two-family home to nine apartments

There was an additional application to convert four apartments to five at 259 Broadway, but the applicant withdrew after their first hearing.

If all of these projects are approved, the net change will be an additional 26 homes, which represents a 0.1% increase relative to the 20,460 dwellings that Arlington had as of the 2020 census. It’s been a very slow trickle.

The MBTA Communities act was a meaningful reform which is just starting to make a difference. It’s bringing proposals for smaller multi-family homes that used to be the mainstay of our housing stock, but are generally rare today. However, the MBTA Communities Act is only one tool and Massachusetts will have to do more in order to build the 222,000 homes we need.
