Even in the midst of a housing crisis, zoning laws prohibit most homeowners in cities and towns around Boston from adding accessory dwelling units (ADUs) to their single family houses. An ADU is an apartment within or behind an own- er-occupied single family house that appears from the street to be a single-family as opposed to a two-family house.
Homeowner-voters can be reassured that new rental hous- ing that could be added as ADUs would be highly dispersed and barely visible. The houses are owner-occupied; the land- lord lives next to the ADU renters, so the risk of property-ne- glect or loud parties is minimal. The houses also have to look like single family houses. Since household sizes are shrinking, new residents in ADUs might maintain current neighborhood population densities, but are unlikely to increase them.
Moreover, ADUs are permitted at such low levels now — only 2.5 permits annually per municipality where they are allowed — that permitting levels could increase substantially without being at all noticeable in neighborhoods. If the region were to average five permits per municipality per year across 100 municipalities, over a decade, ADUs could provide 5,000 apartments, dispersed among 538,000 single family houses. Less than one in 100 houses would have an ADU, yet the new rentals would house thousands of people.

Prof. Christophe Reinhardt runs the MIT Sustainable Design Lab. On Nov. 25, 2019 he gave a very interesting presentation, including talk and slides, that shows a pathway to make more housing, all kinds of housing, and greater housing density both more palatable in Arlington, and actually desirable. He also stressed the importance of paying attention to housing now in order to meet the climate change challenge. Charts (starting about 10 min in) show how drastically we need to reduce our carbon footprint to reach net zero by 2050. Buildings today account for about 40% of our carbon emissions world wide. What we build today will likely be around through 2050.
Paying attention to housing design is important to create a sustainable environment.

He uses research, drawn from around the world and locally, to show what measurable attributes make local communities desirable to live in and what attributes of housing make residents happy.
Key attributes for success (slide is at about 18:15 min. in presentation):
1. Economic opportunities (proximity to work opportunities)
2. High quality living (daylight access for buildings, streets, walkable, mixed use, micro-units, vibrant public spaces, organic food, fitness opportunities)
3. Sustainability (comfortable work and play and living spaces, resource efficiency)
The presentation was arranged by the Robbins Library. It was developed and recorded by Science for the Public as part of it’s lecture series.

Interested in new policy developments on housing production in the Greater Boston area? The latest research from Mass Housing Partnership (MHP) is of interest. They just released (Dec. 18, 2019) in interactive map showing relative housing density around every mass transit and commuter rail station in the system, concluding that the region could add 235,000 units if every community allowed density as of right in the area around transit.

CHAPA has legislation pending that would require municipalities served by transit to allow higher density as of right within a certain distance from transit stations. You’ll see that the density around Alewife is not too bad in the context of the entire system.

This is mostly because of very high density in Cambridge near Alewife, but the density of two and three families in East Arlington shows better housing density than the sea of single family zoning around many commuter rail stops.

Equitable Arlington, along with City Life/Vida Urbana and the Harvard Legal Aid Bureau, supports the legacy tenants of 840/846 Massachusetts Avenue in their resistance to rent increases of up to 50%. We urge the buildings’ owner, Torrington Properties, to continue negotiating an agreement with the tenants rather than pursue legal action likely to end in housing court. If more gradual increases are incompatible with Torrington’s business plan, we hope to see the sale of the property to the Housing Corporation of Arlington or another buyer who is committed to keeping the existing tenants in their homes.

The property, whose two larger buildings date to 1940 and 1963, faces Arlington High School, within easy reach of shopping and transit. It occupies one of relatively few spots in Arlington where people can live without a car. (Equitable Arlington and the MBTA Communities plan seek to encourage exactly this kind of housing.) Many of the middle- and lower-income tenants have been there for decades, including teachers, musicians, and some Section 8 voucher recipients. Some are immigrants with limited English. Laura Frost, who has lived there for 20 years, describes the apartments as “unofficial,” and therefore legally unprotected, affordable housing. Erica Schwarz, executive director of the Housing Corporation of Arlington, concurs: “There are so few places where low-income tenants are in units that aren’t restricted.”

When Torrington Properties bought the buildings in 2019, it did not raise rents right away. Instead, the company pursued a familiar strategy of remodeling apartments when tenants moved out and then marketing them as “luxury” units. More recent arrivals are paying typical market rents. Of the longtime residents, several have left because they were worried about being pushed out to make way for more remodeling and steep rent increases, says Frost, who leads the tenants’ association. All have been tenants at will since Torrington bought the property, with their rents not rising but also not guaranteed by 12-month leases. In November 2022, she says, Torrington distributed a list of target rents for all of the units. A few months later, it informed legacy tenants, then about 20 in number, that they needed to either sign leases at the new rates or move out.
“Our position was never ‘You can’t raise rents ever,’” says Frost, who recognizes that Torrington can legally set rents at any level. Working with City Life/Vida Urbana, she hoped for an agreement for more gradual rent increases, like the one Torrington had just reached with tenants near Forest Hills in Boston. By last spring, however, negotiations had broken down. A rally she organized in September drew Reps. Garballey and Rogers. In February, Torrington sent the legacy tenants notices to quit. We are encouraged that negotiations have since resumed. At the same time, we support a more sustainable option for these tenants and anyone who lives there in the future, as well as Arlington as a whole: a commitment, perhaps by a new owner, to keeping some units affordable in the long term.
Schwarz, of the Housing Corporation of Arlington, has discussed purchasing the property from Torrington, which named a price she describes as “a few million dollars more” than HCA can offer. She has been exploring alternative ways to structure a purchase. This would include drawing on the Town of Arlington’s ARPA funds, as well as seeking mission-aligned equity partners for the project under a “mixed income” model. This would not displace any current tenants, but would, over time, provide a very high percentage of affordable units at a range of income levels, while also providing middle-income and market rate units.
Equitable Arlington supports common-sense reforms that allow for more housing options and tenant protections for current and future Arlington residents. We support increased funding for affordable housing, both through the Affordable Housing Trust Fund and state and federal subsidies, and a wider range of housing choice for every income level and every life stage. We also champion housing that is sustainable, equitable, and accessible, including locating additional housing near public transportation, all of which we believe will make Arlington an even more welcoming community.
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.
A municipality’s master plan is intended to set the vision and start the process of crafting the future of the municipality in regard to several elements, housing, history, culture, open space, transportation, finance, etc. Arlington began a very public discussion about these issues and the development of the Master Plan in 2012. In 2015, after thorough community wide discussion, the Master Plan was adopted by Town Meeting. This year, 2019, the focus is on passing Articles that will amend the current zoning bylaws in order to implement the housing vision that was approved in 2015.
Beginning last July, 2020, the Town of Arlington and community groups in the town are sponsoring a number of webinars and zoom conversations addressing the need for affordable housing programs in Arlington. Several factors contribute to the Arlington housing situation: diversity of housing types, prices, diversity of incomes, availability of housing subsidies, rapid growth in property values that greatly exceed the rate of growth of income.
But racism, both historic and current, continues to stand out as a significant force contributing to the difficult housing situation.
One of the first public discussion in the Town on this subject was organized by Arlington Human Rights Commission (AHRC) on July 8, 2020. View it here:
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.
