The new proposal is just the most recent step in a process that reaches back almost a decade, culminating in the Master Plan (2015), the Housing Production Plan (2016) and the mixed-using zoning amendments of 2016. The Town has consistently proposed smart growth: more development along Arlington’s transit corridors to increase the tax base, stimulate local commerce, and provide more varied housing opportunities for everyone, including low and moderate income Arlingtonians. This year’s proposals are no head-long rush into change. Today’s debate is similar to the debate before Town Meeting three years ago. If anything, progress has been frustratingly slow. To realize the Master Plan’s vision of a vibrant Arlington with diverse housing types for a diverse population, we must stay the course on which we have been embarked for so long.

In 2015 Town Meeting approved the Master Plan. Following is the Housing chapter of that plan. It contains a great deal of information about details of the housing situation in Arlington, challenges of housing price increases, needs for specialty housing, opportunities for meeting these needs, etc. The authors found that “most cities and towns around Arlington experienced a significant rise in housing values from 2000 to 2010. A 40 percent increase in the median value was fairly common. However, Arlington experienced more dramatic growth in housing values than any community in the immediate area, except Somerville. In fact, Arlington’s home values almost doubled.” This and related data helps explain why the need for affordable housing is now so acute.
Dave Weinstock, an Arlington resident interested in affordable housing wondered about the concept of “developer math”. The math involved in planning an affordable housing projects is a problem that needs to get solved in order to have anything built here in Arlington, or anywhere. This topic comes up frequently in community discussions about the need for more housing.
Questions are raised around:
- 1- Why build so many units vs. smaller buildings
- 2- Why parking is costly and inefficient use of land
- 3- Why can’t more affordable or all affordable units be built?
- 4- The cost of subsidizing affordable units and how that may translate to higher rental rates/costs, etc.
Dave found a great Architecture and Development firm in Atlanta (Kronberg Urbanists + Architects, based in Atlanta GA) that lays out a nice presentation, includes sample proformas, and real life scenarios that may help us understand this piece of the puzzle better when evaluating any project and how developers may be incented to build certain types of projects or do certain types of work.
Here is a link, reformatted to be within this website, to the presentation, showing the varieties of choices, costs, formulas and outcomes developers consider before deciding if the project can be built: https://equitable-arlington.org/developer-math_kua_071420/
Much of our hope for more affordable housing depends on the market forces of capitalism and the willingness of developers to build for good, not just for profit. But the developers must be able to cover their costs. Many communities are highly skeptical of developers, assuming the community will get tricked, the developer will get greedy and the promised housing will be a disappointment. Trust is needed. But so is verification. We all need to learn the developer math.
What are the math factors that a developer considers before deciding to build affordable housing?

The presentation, dated March 11, 2019, includes slides used to present the information necessary to understand the rationale for zoning changes, the location of the zoning areas under consideration and the charts, tables and maps that help describe the situation. The proposed zoning changes, especially articles 6, 7, 8, 11 and 16, only cover changes affecting about 7% of the Town, those parts of the Town that are currently zoned R4-R7 and the B zoning districts.
An ADU is a separate, smaller living unit with its own kitchen and bathroom facilities and separate entrance that is included within a larger resident (type 1), attached to a residence (type 2) or located in an accessory (“detached”) structure on the same lot as a main residence (type 3). For a variety of reasons, primarily cost and feasibility, the type 1 ADUs are by far the most common.
Article 43 on Arlington’s warrant for Spring 2021 Town Meeting would allow accessory dwelling units in connectin with single-family dwellings, two-family dwellings and duplex dwellings, as long as the ADUs can conform to dimentional requirements in existing zones (aka R0, R1, R2, B) and all code requirements. These dimensional requirements including setbacks, side yards, height, etc.
The sizes of these ADUs are determined by the size of the finished area of the specific home and must meet the dimensional requirements of the zoning district. Many homes in Arlington may not qualify for a Type 2 (attached) or Type 3 (detached) ADU. This chart shows the probable average square footage size of an ADU in each of the Town’s 21 precincts. There is a considerable difference, ranging from 479sf in precinct 4 to 885sf in precinct 8. The town wide average is 652 sf, not very big but a perfect size for an individual looking for a smaller, less expensive home in Arlington. No matter how big the home, the maximum size is capped at 900sf.

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.
Restrictive covenants are a “list of obligations that purchasers of property must assume … For the first half of the 20th century, one commonplace commitment was a promise never to sell or rent to an African American”. [1] These covenants gained popularity after the Supreme Court’s 1917 decision in Buchanan v. Warley.
Rothstein’s book The Color of Law mentions examples from Brookline, MA; Arlington, MA has examples of it’s own. We’ll look at one from an East Arlington deed dating to 1923. Credit to Christopher Sacca for finding these documents.
First, a land plan to establish content. Below is the subdivision plan for a farm owned by Herbert and Margaret Allen. I count a little over 200 lots in this subdivision. The plan itself states that “no single house shall cost less than $6,000 and no double house shall
cost less than $8,000″. This language also appears in the property deed.

One of the deeds from these parcels appears in book 4631 page 218 and book 4631 page 219, in the Southern Middlesex registry of deeds.
Here’s page 218; the deed begins at the bottom.

Here’s page 219. The racial covenant appears halfway down the page. It reads “No sale or lease of any said lots shall be made to colored people, no any dwelling on any said lots be sold or occupied by colored people”.

The 1920’s were a time of significant residential growth in Arlington, as farmers (called “Market Gardeners” at the time) subdivided and sold off their land. This example shows that Arlington, MA landowners employed some of the same discriminatory tactics for segregation as other communities in the United States. It would take further research to determine how common the use of such covenants was early twentieth-century Arlington.

In a 2019 study, MAPC found that:
- Three out of ten spaces sit empty during peak demand
- The key factors that drive parking demand are parking supply, transit accessibility and the percentage of deed-restricted units
This study raises important questions about the wisdom of continuing to commit large sections of the land area of our municipalities to be on reserve for parking cars. Such extra space could be used to benefit the open space, environmental sustainability and the need for more housing.
It’s the time of year when folks in Arlington are taking out nomination papers, gathering signatures, and strategizing on how to campaign for the town election on Saturday April 1st. The town election is where we choose members of Arlington’s governing institutions, including the Select Board (Arlington’s executive branch), the School Committee, and — most relevantly for this post — Town Meeting.
If you’re new to New England, Town Meeting is an institution you may not have heard of, but it’s basically the town’s Legislative Branch. Town Meeting consists of 12 members from each of 21 Precincts, for 252 members total. Members serve three-year terms, with one-third of the seats up for election in any year, so that each precinct elects four representatives per year (perhaps with an extra seat or two, as needed to fill vacancies). For a deeper dive, Envision Arlington’s ABC’s of Arlington Government gives a great overview of Arlington’s government structure.
As our legislative branch, town meeting’s powers and responsibilities include:
- Passing the Town’s Operating Budget, which details planned expenses for the next year.
- Approving the town’s Capital Budget, which includes vehicle and equipment purchases, playgrounds, and town facilities.
- Bylaw changes. Town meeting is the only body that can amend the towns bylaws, including ones that affect housing — what kinds can be built, how much, and where.
Town Meeting is an excellent opportunity to serve your community, and to learn about how Arlington and its municipal government works. Any registered voter is eligible to run. If this sounds like an interesting prospect, we encourage you to run! Here’s what you’ll need to do:
- Have a look at the town’s Information for new and Prospective Town Meeting Members.
- Contact the Town Clerk’s office to get a set of nomination papers. You’ll need to do this by 5:00 PM February 12th, 2025 at the latest.
- Gather signatures. You’ll need signatures from at least ten registered voters in your precinct to get on the ballot (it’s always good to get a few extra signatures, to be safe).
- Return your signed nomination papers to the Clerk’s office by February 14, 2025 at 5:00 PM.
- Campaign! Get a map and voter list for your precinct, knock on doors, and introduce yourself. (Having a flier to distribute is also helpful.)
- Vote on Saturday April 5th, and wait for the results.
Town Meeting traditionally meets every Monday and Wednesday at 8:00 PM, starting on the 4th Monday in April (which is April 28th this year), and lasting until the year’s business is concluded (typically a few weeks).
If you’d like to connect with an experienced Town Meeting Member about the logistics of campaigning, or the reality of serving at Town Meeting, please email info(AT)equitable-arlington.org and we’d be happy to make an introduction.
During the past few years, Town Meeting was our pathway to legalizing accessory dwelling units, reducing minimum parking requirements, loosening restrictions on mixed-use development in Arlington’s business districts, and adopting multi-family zoning for MBTA Communities. Aside from being a rewarding experience, it’s a way to make a difference!
