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.

Accessory Dwelling Units (aka “granny flats”)
The following information was presented to the Arlington Redevelopment Board in October, 2020 by Barbara Thornton, TMM, Precinct 16
This Article proposes to allow Accessory Dwelling Units, “as of right”, in each of the 8 residential zoning districts in Arlington.
Why is this zoning legislation important?
Arlington is increasingly losing the diversity it once had. It has become increasingly difficult for residents who have grown up and grown old in the town to remain here. This will only become more difficult as the effects of tax increases to support the new schools, including the high school, roll into the tax bills for lower income residents and senior citizens on a fixed income. For young adults raised in Arlington, the price of a home to buy or to rent is increasingly out of reach.
Who benefits from ADUs?
- Families benefit from greater flexibility as their needs change over time and, in particular providing options for older adults to be able to stay in their homes and for households with disabled persons or young adults who want additional privacy but still be within a family setting.
- Residents seeking an increase in the diversity of housing choices in the Town while respecting the residential character and scale of existing neighborhoods; ADUs provide a non-subsidized form of housing that is generally less costly and more affordable than similar units in multifamily buildings;
- Residents wanting more housing units in Arlington’s total housing stock with minimal adverse effects on Arlington’s neighborhoods.
What authority and established policy is this built on?
Arlington’s Master Plan is the foundational document establishing the validity and mission for pursuing the zoning change that will allow Accessory Dwelling Units.
Under Introduction in Part 5, Housing and Residential Development, the Master Plan states: Arlington’s Master Plan provides a framework for addressing key issues such as affordability, transit-oriented residential development, and aging in place.
The Master Plan states that the American Community Survey (ACS) reports that Arlington’s housing units are slightly larger than those in other inner-suburbs and small cities. In Arlington, the median number of rooms per unit is 5.7. There is a great deal of difference in density and housing size among the different Arlington neighborhoods. The generally larger size of homes makes it easier to contemplate a successful move to encourage ADUs.
What do other municipalities do?
According to a study (https://equitable-arlington.org/2020/02/16/accessory-dwelling-units-policies/), by 2017 65 out of 101 municipalities in the greater Boston (MAPC) region allowed Accessory Dwelling Units by right or by special permit. The average number of ADU’s added per year was only about 3. But by 2017, Lexington had 75 ADUs and Newton had 73. Both of these communities were among about 10 “as of right” municipalities in the MAPC region. This finding suggests that communities with more restrictions are less likely to see any significant affordable housing benefits.
Even in the midst of a housing crisis in this region, according to Amy Dain, housing expert, (https://equitable-arlington.org/2020/02/18/zoning-for-accessory-dwelling-units/) most municipalities still have zoning laws that restrict single family home owners from creating more affordable housing.
And this is despite the fact that, as according to Banker & Tradesman, March 10, 2020: https://www.bankerandtradesman.com/63-percent-in-greater-boston-back-adus/, 63% of people in the region approve of ADUs. California has recently passed strong pro-ADU legislation. A study by Zillow further corroborated this strong interest in communities across the US, including our region. https://equitable-arlington.org/2020/03/10/adu-popularity/.

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:
Why Is This Our Issue & What Should We Do About It?
(presented by Adam Chapdelaine, Town Manager, to Select Board on July 22, 2019)
Overview

Since 1980 the price of housing in Massachusetts has surged well ahead of other fast growing states including California and New York. While the national “House Price Index” is just below 400, four times what an average house might have cost in 1980, a typical house in Massachusetts is now about 720% what it was in 1980. Median household income in the state has only increased about 15% during the same period. No wonder people in Arlington are feeling the stresses of housing costs if they want to live here and are feeling protective of the equity value time has provided them if they bought years ago.
In response to concerns about zoning, affordable housing and housing density, the Town joined the “Mayors’ (and Managers’) Coalition on Housing” to address these growing pressures. This 12 page slide deck presentation outlines the key data points, the number of low and very low income households in Arlington, the rate of condo conversion that is absorbing rental units, etc.
Solutions are offered including:
• Amendments to Inclusionary Zoning Bylaw
• Housing Creation Along Commercial Corridor – Mixed Use & Zoning Along Corridor
• Accessory Dwelling Units – Potential Age & Family Restrictions
• Other Tools Can Be Considered That Are Outside of Zoning But Have An Impact on Housing
Chapdelaine’s suggested next steps are:
• Continued Public Engagement
• Town Manager & Director of DPCD Meet with ARB
• Select Board & ARB Hold Joint Meeting in Early Fall
• ARB Recommends Strategies to Pursue in Late Fall/Early Winter
The Select Board approved the suggested next steps and a joint ARB/ Select Board meeting should be scheduled in the near future.
Note from Reporter: As a community, Arlington has long prided itself on its economic diversity. With condo conversions, tear downs leading to “McMansions”, higher paid workers arriving in response to new jobs, etc., Arlington is at great risk of losing this diversity that has long enriched the community. Retirees looking to downsize and young people who have grown up in Arlington looking for their first apartment are finding it impossible to stay in town. Shop keepers and town employees are challenged to afford the rising housing costs. With a reconsideration of zoning along Arlington’s transit corridors, Arlington NOW has an opportunity to create new village centers, like those recommended in the recent STATE OF HOUSING report. These village centers along our transit corridors could be higher, denser but also offer the compelling visual design and amenities desired by people who want to walk to cafes, shops and public transit.
It’s New Year’s eve and I’m determined to get my third and final “Arlington 2020” article written and posted before 2021 rolls in. I’ve written these articles to paint a picture of Arlington’s housing stock, and how our housing costs have changed over time. The first article looked at the number of one-, two-, and three-family homes and condominiums in Arlington. The second article looked at how the costs of these homes has varied over time.
In this article, I’m going to look at the per-unit costs for our different housing types. The per-unit cost is just the assessed value, divided by the number of units. For condos and single-family homes, the unit cost is simply the assessed value. For two-family homes, it’s the assessed value divided by two. For a ten-unit apartment building, it’s the assessed value divided by ten. We’ll look at the price ranges within housing types, as well as the general differences between them.
The information here doesn’t include residential units from Arlington’s 76 mixed-use buildings. (My copy of the assessor’s data doesn’t distinguish between residential and commercial units in these buildings; I’ll try to say more about them in 2021.) It also omits units owned by the Arlington Housing Authority.
Condominiums
Condominiums provide the most variety and cost diversity. A condo can be half of a duplex, or part of a much larger multi-family building. The low end of the scale tends to be 500–600 square foot units that were built in the 1960’s; the high end tends to be more spacious new construction.

This graph is a histogram, as are the others in this article. The horizontal axis shows cost per unit, and the vertical axis shows the number of units in each particular cost band.
The per-unit price distribution is
min | 1st quartile | median | mean | 3rd quartile | max |
$92,600 | $344,450 | $473,100 | $500,086 | $640,850 | $1,241,000 |
Single-family homes
Single family homes are heavily concentrated around the $700,000 mark. There’s very little available for less than a half million dollars.

Per unit rice distribution:
min | 1st quartile | median | mean | 3rd quartile | max |
$103,700 | $679,900 | $771,900 | $825,172 | $908,750 | $3,232,700 |
The $103,700 single-family home deserves some explanation. The property straddles the border between Arlington and Lexington; it appears that the $103k assessed value reflects the portion that lies in Arlington.
Two-family Homes
Two-family homes are the bread and butter of East Arlington; they’re also common in the blocks off Mass ave near Brattle Square and the heights. Many of these homes are older and non-conforming, and they’re gradually being renovated and turned into condominiums.
As a reminder, these are costs per unit (as opposed to the cost of the entire two-family home).

Per unit price distribution:
Min | 1st quartile | median | mean | 3rd quartile | max |
$209,050 | $440,550 | $472,000 | $479,175 | $508,588 | $1,140,450 |
Three-family Homes
Unlike Dorchester and Somerville, three-family homes are not a staple of Arlington’s housing stock. But we have a few of them. Most were built between 1906 and 1930.

Per-unit price distribution:
Min | 1st quartile | median | mean | 3rd quartile | max |
$227,567 | $313,733 | $336,950 | $344,292 | $362,600 | $719,000 |
Small Apartments (4–8 units)
The majority of Arlington’s small apartment buildings were constructed during the first half of the 20th century. The most recent one dates from 1976.

Per-unit price distribution:
Min | 1st quartile | median | mean | 3rd quartile | max |
$154,950 | $202,950 | $227,775 | $231,619 | $255,775 | $403,875 |
Large Apartments (9+ units)
You’ll see three outliers in the per unit-cost distribution for large apartment buildings. These correspond to the newest apartment complexes in Arlington: The Legacy (2000), Brigham Square (2012), and Arlington 360 (2013).

Per-unit price distribution:
Min | 1st quartile | median | mean | 3rd quartile | max |
$117,013 | $141,383 | $153,006 | $195,789 | $170,973 | $474,631 |
All combined
Finally, we’ll put it all together in one picture, representing nineteen-thousand and some odd homes in town.

Per-unit price distribution:
Min | 1st quartile | median | mean | 3rd quartile | max |
$92,600 | $417,175 | $555,825 | $587,975 | $759,900 | $3,232,700 |
While there are lower-priced options available, a person coming to Arlington should expect to buy (or rent) a property that costs just shy of half a million dollars (or more).
Here is a spreadsheet with the cost distributions mentioned in this article.
The City of Somerville estimates that a 2% real estate transfer fee — with 1% paid by sellers and 1% paid by buyers, and that exempts owner-occupants (defined as persons residing in the property for at least two years) — could generate up to $6 million per year for affordable housing. The hotter the market, and the greater the number of property transactions, the more such a fee would generate.
Other municipalities are also looking at this legislation but need “home rule” permission, one municipality at a time, from the state to enact it locally. Or, alternatively, legislation could be passed at the state level to allow all municipalities to opt into such a program and design their own terms. This would be much like the well regarded Community Preservation Act (CPA) program that provides funds for local governments to do historic preservation, conservation, etc.
This memorandum from the City of Somerville to the legislature provides a great deal of information on the history, background and justification for such legislation.
House bill 1769, filed January, 2019, is an “Act supporting affordable housing with a local option for a fee to be applied to certain real estate transactions“.

When you love the place you live and you want to help it become even better, how can you make a difference? Arlington is an extremely civically active community, with hundreds of residents involved in Town Meeting, several dozen boards and committees, and numerous other groups that play an important role in improving our town. The vast array of options can be a bit dizzying for a newcomer to sort through.
Fortunately, Arlington has recently launched Arlington Civic Academy to provide interested residents with a pathway to becoming more civically literate and involved. Ably organized by Joan Roman, Arlington’s Public Information Officer, Civic Academy takes place over the course of six weeks and aims to provide participants with the information they need for constructive civic engagement. Applications are open from now until August 4th for the fall session, which will take place between September 12th and October 17th.
Find Out How the Town Works
It’s clear that town government takes the Academy seriously. The Town Manager, Select Board Chair, Town Moderator, and the heads of several town departments have stayed late into the evening to attend Civic Academy sessions. Their formal presentations do a great job of explaining how different areas of town government work and how best to get involved, but the chance to meet them and ask them questions is equally valuable. The participants usually have a lot of very insightful questions, and it’s a great opportunity to learn more and become a more effective advocate in the future.
Participants Make Arlington Civic Academy Great
The other participants are another great part of the program. It’s also a great chance to make connections with other people who are equally enthusiastic about learning and getting involved in making their town a better place. There have been two sessions of the program so far, and several participants have gone on to run for Town Meeting, join the Master Plan Update Advisory Committee, volunteer for last fall’s tax override campaign, and propose warrant articles. We just had a get-together for members of both Civic Academy sessions to meet each other and network, and are hopeful that Civic Academy alumni can help connect future participants in the program to opportunities to get involved in helping Arlington become even better.
Helping Others Learn to Navigate Town Processes
I ran for Town Meeting this spring after attending Civic Academy last fall, and I found that it served me well after I was elected. It taught me how the budgeting process worked, including all the steps from the Town Manager’s office working with individual departments, the Finance Committee compiling a cohesive budget, and Town Meeting approving that budget. When constituents from my precinct have questions about how to get help with something from the town, I know which boards or committees or town departments they should reach out to. I also have a better understanding of the current constraints and opportunities faced by our town across multiple areas.
When I started working with Paul Schlictman on advocating for extending the Red Line further into Arlington, I reached out to the members of my Civic Academy class to see if they were also interested, and several of them were incredibly generous with their time and helped us set up our website and mailing list. I would highly recommend applying to Civic Academy, and I’m very thankful that the town puts so much effort into making it a great experience.
In the past few weeks, a number of highly respected Arlington organizations have come out in support of the MBTA Communities Plan. Here are a few. We will continue to update this list as it grows.
Greater Boston Interfaith Organization
This week the Greater Boston Interfaith Organization’s Arlington members released a letter of support, stating:
Arlington GBIO members support the Arlington Redevelopment Board’s proposal for the Article 12 of the Fall 2023 Special Town Meeting (MBTA Communities Overlay District) to enact changes in Arlington’s zoning by-laws that will allow for more multi-family housing to be built by right. We support an article that goes beyond the minimum capacity required by law in order to encourage the construction of a meaningful number of additional homes of various sizes beyond the number already present in Arlington.
Arlington Chamber of Commerce
The Arlington Chamber of Commerce sent a letter supporting the MBTA Communities Plan on October 2, saying:
The Arlington Chamber of Commerce believes that the MBTA Working Group’s proposal presents a strong plan for both housing and commercial growth. Arlington’s existing and future small businesses will benefit from an increased customer base and foot traffic resulting from additional housing units.
Division of Diversity, Equity and Inclusion
Arlington’s Division of Diversity, Equity and Inclusion wrote to the Arlington Redevelopment Board in support of the MBTA Communities Plan:
The DEI Division would like to formally voice our support for the Working Group’s effort to create a zoning plan that would allow for more multi-housing opportunities at varied price points across Arlington. Only 9% of Arlington’s land is devoted to multifamily housing, and even where building multi-family housing is allowable, it is not permitted by right. This does not provide suitable conditions for a range of housing types to exist. The current price point of homes in Arlington are far beyond the reach of most residents, regardless of their status as a member of a protected class. stating:

Clean Energy Future Committee
The Clean Energy Future Committee said passage of the MBTA Communities Zoning was crucial because:
Passage of the MBTA Communities zoning amendment at this fall’s Special Town Meeting is the only viable pathway for Arlington to participate in the State’s Fossil Fuel Free Demonstration Program (Demonstration Program), which would allow implementation of the Clean Heat bylaw and home rule petition passed overwhelmingly by Arlington Town Meeting in 2020. Participation in the Demonstration Program will allow the Town to prohibit the installation of natural gas, oil, propane, and other fossil fuel infrastructure in new buildings and major renovations. Town Meeting sent a clear message in 2020 that enacting the Fossil Fuel Bylaw was a priority, and we–the CEFC, Town administrators, and elected and appointed bodies–have an obligation to act upon that priority; passage of the MBTA Communities zoning amendment is an essential step to carrying out the will of Town Meeting.
Mothers Out Front
As we previously reported, the Arlington chapter of Mothers Out Front supports the MBTA Communities Plan, writing:
A revised zoning by-law to allow for more multi-family housing will reduce pressure to build single family homes on undeveloped land elsewhere in Massachusetts. This safeguards undisturbed ecosystems and provides real alternatives to automotive commutes in the region, reducing both congestion and fossil fuel emissions.
Massachusetts’ 2020 Economic Development Bill included a set of housing choice provisions: these require communities served by the MBTA to provide a district of reasonable size where multi-family housing is allowed by right. The law gives us significant flexibility to design a district that best suits our needs, but the district must allow housing suitable for families with children, without age restrictions, and at a rate of at least 15 dwelling units per acre. Arlington is one of 175 MBTA communities in Massachusetts that share in the responsibility for meeting these requirements.

The law requires a “district of reasonable size”, but what does that mean? Throughout much of 2021 the Massachusetts Department of Housing and Community Development (DHCD) worked on a set of supporting regulations that set the district requirements according to the type of transit service a community has, the number of existing homes in the community (as of the 2020 Census), and the amount of developable land near transit stations. The specifics vary by community, but here is what the requirements mean for Arlington:
- Our district needs a capacity of (at least) 2,046 homes. This isn’t a requirement to build 2,046 additional homes; instead, it reflects the total number of homes that district might contain in the future. For example, if a parcel with a two-family home were rezoned to allow a three-family home, that single parcel would have a capacity of three.
- Our district needs to allow multi-family housing by right. “By right” means that the development only requires a building permit, where the Building Inspector determines whether the project complies with zoning and building codes. While Arlington allows multi-family housing (three or more dwellings on a single parcel) in some areas, such projects are not allowed by right.
- Our district needs to allow (at least) 15 dwellings/acre. This is more or less in line with the density of the streetcar suburbs that were built in East Arlington during the 1920s. Although portions of Arlington likely meet the density requirement, none of these areas currently comply, as they don’t allow multi-family housing to be built by right.
- Our district needs to be at least 32 acres, but it could be larger. We have flexibility here, as we’ll discuss in a moment.
- Finally, due to the lack of developable land around the Alewife T station, Arlington is free to locate its multi-family district (or districts) anywhere in town. We’re not tied to any particular geographic location.
The new law’s requirements provide Arlington with a great deal of flexibility. We’re free to place our district (or districts) anywhere in town, and we’ll be able to choose from a variety of options as long as they meet the requirements set forth above. For example, providing the capacity of 2,046 homes in the minimum district size of 32 acres would give us a density of 64 dwellings/acre; roughly the scale of mid-rise apartment buildings. On the other hand, if we went with the minimum density of 15 dwellings/acre, we’d have a 135 acre district that allowed smaller multi-family homes. Our district can be anywhere within this range; we also have the option of having multiple districts, with smaller multi-family buildings in some areas of town and larger multi-family buildings in others.
Arlington has a track record of producing thorough and comprehensive planning documents, such as our Master Plan, Net Zero Action Plan, Sustainable Transportation Plan, and Housing Production Plan. These plans contain plenty of building blocks that could be used to formulate a compliant multi-family district. Viewed in that light, the MBTA community requirements are an opportunity to meet some of the goals we’ve already set for ourselves; we just have to go about it in a way that satisfies the law’s new requirements.
Arlington has one unique consideration, which doesn’t apply to most MBTA communities. In 2020, Arlington’s Town Meeting sent a home rule petition to the state legislature, asking for permission to regulate the use of fossil fuels in new building construction; it’s an important component of our plan to become carbon-neutral by 2050. A number of other communities in the Commonwealth filed similar petitions, and the legislature responded by establishing a pilot program: ten cities and towns will be allowed to enact “fossil fuel bans”, but only if they (a) have 10% subsidized housing, (b) achieve safe harbor via compliances with an approved housing production plan, or (c) establish a multi-family district of reasonable size by February 2024. Arlington doesn’t meet the subsidized housing requirement (only 6.54% of our homes are on the subsidized housing inventory), and we’re unlikely to gain safe harbor status during the next year; our most viable path to participation hinges on meeting the multi-family requirements.
In summary, the multi-family requirement for MBTA communities creates new requirements for Arlington, while also presenting us with new opportunities: the opportunity to meet planning goals, the opportunity to meet sustainability goals (e.g., by regulating fossil fuel use in new construction), and the opportunity to reimagine how we do multi-family housing in Arlington as our town moves forward into the twenty-first century.
