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.

Some years back, I took a bus ride to a climate rally in New York City with a bunch of other activists. My seatmate was 12 years old, a smart kid from the suburbs who had never been to New York. As we approached Manhattan on the Cross Bronx Expressway, he looked out at a block of concrete apartment buildings and said something like: This is what happens when you don’t care about the environment. Actually, I replied, this is green living: People live close together; they can walk or take public transit; they live in apartments, share walls and heat and are relatively energy efficient; their carbon footprint is far lower than a family in a “green”, leafy single-family suburban house.
But my traveling companion was not altogether wrong about what he saw: New York, Boston, and every other city are now at pains to make a humane, equitable adaptation to a changing climate. We don’t want to create living spaces that bake in the sun’s heat, that have no shade or greenery or open space, surrounded by asphalt and highway, beset with deadly particulate pollution, flooding risk, and polluted stormwater runoff. Heat and air pollution are an expensive and deadly burden that fall especially heavily on low- and middle-income folks — a burden cruelly increasing with climate change.
As we decide what kinds of housing we are going to encourage in Arlington, we can do things in a more compassionate and inclusive way. We can incorporate environmental and aesthetic concerns, while allowing a mix of housing types that accommodate people of diverse incomes, family sizes, and life stages.
We can address both the climate crisis and the crisis-level housing shortage in Greater Boston. Environmental concerns are not a reason to say no to new housing. Rather, they are a part of the housing solution, in Arlington and regionally.
As Laura Wiener detailed in another post, The Housing Corporation of Arlington development at 10 Sunnyside (between Broadway and Mystic Valley Parkway, near Route 16), is an excellent example of implementing environmental/sustainability measures in an affordable (i.e. income-subsidized) multi-family dwelling. It is Passive House certified: An extremely stringent standard, using a combination of advanced and repurposed materials, high- and low-tech, to provide human comfort while bringing energy use to an absolute minimum.* The development features plentiful bike parking and a roof garden. It converts previously impervious pavement to landscaping, like planters, where stormwater can infiltrate the ground rather than carrying unfiltered pollutants into Arlington’s water bodies.
Another example of green infrastructure lives charmingly and unassumingly on some of our street corners. In 2020, Arlington installed rain gardens at the corner of Milton Street and Herbert Road in East Arlington. These little curbside oases act as a kind of green filter for storm water, catching pollutants (Fertilizer! Salt! Dog poop! Oil! Brake dust!) before they reach Alewife Brook and the Mystic River. Perhaps co-sited with new housing, wider buildout of rain gardens could keep nutrient pollution out of Spy Pond, preventing nasty algae growth which literally suffocates other aquatic life.
A caveat: We must take care not to load so many creative requirements onto new housing that it doesn’t get built at all. We need the housing. (See “The Problem with Everything-Bagel Liberalism” by Ezra Klein in the New York Times.) And under the new MBTA Zoning that we are required to implement, we must allow three-family housing in our new multi-family zones by right, i.e. without extra requirements or rigamarole.
But we could decide to add incentives to allow more housing above those requirements if such environmental improvements (rain gardens, green roofs, pollinator habitat, Passive House innovations, etc.) are included. Every new building is an opportunity for environmental adaptation. A vision for a greener, cooler, more inclusive Arlington takes shape. We can do this.
New housing development provides an opportunity to incorporate inclusive, environmentally friendly, win-win adaptations. Our environmental and housing goals must not be in tension with each other. With a coordinated approach, we can address the challenges of pollution, climate change, and our chronic and unjust housing shortage.
*As far as I can tell, only two other buildings in all of Greater Boston are Passive House certified: A new multi-family in Roxbury, and a single-family in Somerville.

If you’ve lived in Arlington for a while, your housing costs, whether you rent or own, might be well below what they are for newcomers. Perhaps you, or someone you know is experiencing scary annual rent increases, or would like to buy a house but can’t get near Arlington’s $1 million-plus median price tag.
Arlington, and much of the Commonwealth, has a shortage of housing that is driving up housing prices and increasing homelessness. Renters are particularly hard hit, with median rents over $2500/month. About 1/3 of Arlington’s renters pay more than 30% of their income for housing. In order to get that rent down to something affordable for a low-income household, subsidies are needed. Arlington has been very supportive of building affordable housing, using its CDBG (Federal Community Development Block Grant) and CPA (local Community Preservation Act) funds to that end. It has also worked cooperatively with the Arlington Housing Authority and Housing Corporation of Arlington in support of their affordable housing projects. These subsidy dollars are necessary but not sufficient for building affordable housing.
Land cost is one thing that makes building any housing expensive, and one way to decrease the cost of building affordable housing is to allow more units to be built on a given piece of land. But our zoning limits much of our town to single- and two-family homes on a lot. The Affordable Housing Overlay allows more units to be built on a lot, throughout the Town, and targets those who need it most—low-income households.
A zoning overlay is an alternative set of zoning requirements that can be applied on a piece of land. A builder can choose to build under the alternative Overlay Zoning rules, or under the original zoning, known as the Underlying Zoning. In this case, the proposed Affordable Housing Overlay Zoning can be applied anywhere, on any lot, if at least 70% of the units are priced to be affordable to a household at or below 60% of median income. If 70% of units are affordable, then the structure can be up to 2 stories taller than with the underlying zoning. In addition, any number of units can be built, so long as yard and setback requirements are met. One additional change is that the parking requirement would be a minimum of ½ space per unit. This reflects the actual parking usage at existing affordable housing owned by the Housing Corporation of Arlington. This proposal includes both rental and ownership units that are affordable.
A group of Arlington residents is proposing an amendment to our current zoning to include an Affordable Housing Overlay. This proposal will come before the Redevelopment Board for hearings in winter 2025 (probably during February or March), and then go to Town Meeting in spring 2025. There has already been one informational meeting on November 7 (slides and video), and there may be additional public informational meetings scheduled.

Our communities need more housing that families and individuals can afford. From 2010 to 2017, Greater Boston communities added 245,000 new jobs but only permitted 71,600 new units of housing. Prices are escalating as homebuyers and renters bid up the prices of the limited supply of housing. As a result, one quarter of all renters in Massachusetts now spend more than 50% of their income on housing. (It should be only about 30% of monthly gross income spent on housing costs.) Municipalities have been over-restricting housing development relative to need. The expensive cost of housing not only affects individual households, but also negatively affects neighborhoods and the region as a whole. Lack of affordability limits income diversity in communities. It makes it harder for businesses to recruit employees.
Over the last two years, researcher Amy Dain, commissioned by the Massachusetts Smart Growth Alliance, has systematically reviewed the bylaws, ordinances, and plans for the 100 cities and towns around Boston to uncover how local zoning affects multifamily housing and why local communities failing to provide enough additional housing to keep the prices from skyrocketing for renters and those who want to purchase homes.
Interested in housing affordability and why the cost of housing is increasing so dramatically to prevent average income residents from affording homes in the 100 municipalities around Boston? Arlington and Medford residents are pleased to welcome author Amy Dain to present her report, THE STATE OF ZONING FOR MULTIFAMILY HOUSING IN GREATER BOSTON (June 2019). Learn more about the so-called “paper wall” restricting production, common trends in local zoning, and best practices to increase production going forward.

The Massachusetts Smart Growth Alliance, which commissioned the study, provides the following summary of the four principal findings and takeaways:
1) Very little land is zoned for multi-family housing.
For the most part, local zoning keeps new multi-family housing out of existing residential neighborhoods, which cover the majority of the region’s land area.
In addition, cities and towns highly restrict the density of land that is zoned for multi-family use via height limitations, setbacks, and dwelling units per acre. Many of the multi-family zones have already been built out to allowable densities, which mean that although multi-family housing is on the books, it does not exist in practice.
At least a third of the municipalities have virtually no multi-family zoning or plan for growth.
Takeaway: We need to allow concentrated density in multi-family zoning districts that are in sensible locations and allow for incremental growth over a larger area.
2) We are moving to a system of project-by-project decision-making.
Unlike much of the rest of the country, Massachusetts does not require communities to update their zoning on a regular basis and make it consistent with local plans. Although state law ostensibly requires municipalities to update their master plans every ten years, the state does not enforce this provision and most communities lack up-to-date plans.
Instead, the research documents a trend away from predictable zoning districts and toward “floating districts,” project-by-project decision-making, and discretionary permits. Dain found that 57% of multi-family units approved in the region from 2015-2017 were approved by special permit, 22% by 40B (including “friendly” 40B projects), 7% by use variance, and only 14% by “as-of-right” zoning.
There also seems to be a trend toward politicizing development decisions by shifting special permit granting authority to City Council and town meeting. The system emphasizes ad hoc negotiation, which in some cases can achieve a more beneficial project. Yet the overall outcome is a slower, more expensive development process that produces fewer units. Approving projects one by one inhibits the critical infrastructure planning and investments needed to support the growth of an entire district.
Takeaway: We would be better served by a system that retains the benefits of flexibility while offering more speed and predictability.
3) The most widespread trend in zoning for multi-family housing has been to adopt mixed-use zoning.
83 of out of 100 municipalities have adopted some form of mixed-use zoning, most in the last two decades. There is a growing understanding that many people, both old and young, prefer to live in vibrant downtowns, town centers and villages, where they can easily walk to some of the amenities that they want. Malls, plazas and retail areas are increasingly incorporating housing and becoming lifestyle centers.
Yet with few exceptions, the approach to allowing housing in these areas has been cautious and incremental. These projects are only meeting a small portion of the region’s need for housing and often take many years of planning to realize. In addition, the challenges facing the retail sector can make a successful mixed-use strategy problematic. Commercial development tends to meet less opposition than residential development, even in mixed-use areas.
Takeaway: We need more multi-family housing in and around mixed-use hubs, but not require every project to be mixed-use itself.
4) Despite their efforts, communities continue to build much more new housing on their outskirts rather than in their town centers and downtowns.
About half of the communities in the study permitted some infill housing units in their historic centers, but her case studies show that these infill projects are modest in scale and can take up to 15 years to plan and permit.
On the other hand, many more units are getting built in less-developed areas with fewer abutters. This includes conversion of former industrial properties, office parks, and other parcels disconnected from the rest of the community by highways, train tracks, waterways or other barriers. This much-needed housing can be isolated even when dense, and still car-dependent because of limited access to public transportation and lack of walkability.
Takeaway: We need to allow more housing in historic centers as well as incremental growth around those centers. Furthermore, we need to plan an integrated approach to growth districts so that they can be better connected to the community and the region.
(Elliot L. is an 8th grader at the Ottoson Middle School)
In the middle of COVID-19, I started to notice a large construction project happening right down the street in our little neck of the woods by Thompson school. I simply assumed it was another apartment building, but after asking the adults of my community, I found it was much more impactful than that. Arlington was supporting a large affordable housing project to be established, along with plans of putting Arlington EATS, a food pantry, below it. This got the gears in my tiny sixth grade mind churning. I began asking questions like: how do you apply to live there? How much does it cost? Do the owners provide you with furniture? Of course, most of those questions were answered by my parents, and then quickly put in the back of my mind. However, the idea of affordable housing stuck with me, especially when you can see it from your front porch. Upon reaching the 8th grade, where I am now, I found myself and every student in my class presented with a year long project trying to make change in Arlington. This assignment, called the Civics Action Project, or CAP, guides students to choosing a local issue they wish to address.
The premise got me thinking. How can I help my community with our rising cost of living and need for affordable housing? Initially, the other students and I were overwhelmed by the magnitude of the issue, and had trouble thinking of a reachable solution.
Despite this, a small group of classmates and I were intrigued by a bill mentioned by Claire Ricker, Arlington’s director of Planning and Community Development, during an informational panel. Ms. Ricker talked about the MBTA Communities Act, a law requiring Arlington to create higher-density housing near the T. We knew we had found our goal, to raise awareness and support zoning for affordable housing as part of the act.
However, as our research continued, we learned of the real function of this legislation. The goal of the MBTA communities act is to build more compact middle income housing. This will make it so people like young adults and downsizers can come to live in this town, building their future and contributing to a diverse community. This is an essential step in the right direction for the town, but our strides need to be longer.
In order to support our goal, we still wanted to learn more about Arlington’s affordable housing needs. We wanted to promote those issues, as well as the missing middle housing we desperately need. Our group started by conducting a survey that we posted on Arlington forums, along with directly sending it to as many people as we could. 60 residents responded, and we then shared these results with Select Board member Len Diggins. Here are some of the most interesting results of this survey!
- Many people in Arlington still struggle with home, food, and job insecurities.
- The cost of living has made almost every family surveyed have to change their lifestyle in some way.
- Over 1/3 of Arlington residents believe their salary is not enough to support their families.
- 87% of people think Arlington government is making a subpar effort at combating these issues.
- When asked what they would like to see the town do, Arlington residents supported the idea of building more affordable housing and providing aid and support to local food distribution groups, such as Foodlink or Arlington EATS.
- About half of residents have heard of and know about the MBTA communities act.
After the results of our survey, along with other actions taken to learn more about the MBTA communities act, my group and I came to a conclusion of our plan: In order to try and make a change in Arlington, we were going to spread the word to as many adults as we could in order to support both the higher-density housing the MBTA communities act is focused on, and lower cost housing. While these are separate things, our thinking is that the more people who can vote and hear about this, the more willing they will be to connect and support the different pieces of the puzzle to solve our housing issue. This is not just a one-time thing. The MBTA communities act is a planned, strategic opportunity to make Arlington a better place for the future. We hope with the information provided, you will also keep the cause of affordable housing progressing as well. Thank you for reading!
The calculation for what is permanently affordable housing is complicated. Arlington’s affordable rate is based on a region that includes the Area Median Income (AMI) of the Cambridge-Boston-Quincy region. The rate is adjusted and reset periodically according to federal HUD guidelines. The rate is applied based on family size and on the Town’s definition of what income level is eligible for Inclusionary Housing opportunities in Arlington. In Arlington a 3 person family would qualify if their income was under 60% of AMI. At this time, that is approximately $58,000 for a family of three.
For more information, see this table of income limits from Cambridge’s Community Development Department, and this short paper on affordable housing from the City of Boston.

The Dec. 12 letter from Jo Anne Preston unfortunately repeats misinformation making the rounds in Arlington (“Arlington is a case study in grappling with rezoning“).
At April Town Meeting, the Arlington Redevelopment Board recommended a vote of no action on its warrant article that would have allowed increased density along the town’s commercial corridors in exchange for building more affordable housing (known as “incentive zoning”), when it became obvious that the article would be unlikely to gain a two-thirds vote for passage, in part because of the complexity of what was proposed.
A warrant article to allow accessory dwelling units in existing housing (“in-law apartments”) gained more than 60 percent of the vote at Town Meeting but not the two-thirds vote necessary to change zoning.
The letter writer mentioned “naturally occurring affordable apartment buildings.” The typical monthly rent for an apartment in those older buildings ranges from about $1,700 for a one-bedroom to about $2,300 for a two-bedroom, according to real estate data from CoStar. Those are not affordable rents for lower-income people. For example, a senior couple with the national average Social Security income of about $2,500 per month would spend most of their income just to pay the rent.
We need to protect the ability of people with lower incomes to withstand rent increases and gentrification. That, however, requires a different approach than hoping for naturally occurring affordable housing to be there even five years from now.

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/.

The citizen participation process including presentations, discussions, public hearings, letters and comments has been long and arduous. The issues are complicated and sometimes feelings run high. In such situations, there can be a feeling that citizens have not been heard. This document, “Guide to Zoning Amendments Related to Multifamily Uses and Mixed-Use“, summarizes many of the issues that have been raised and the changes that have been made in the zoning Articles as a result of the citizen participation in the public review process. Citizens have been heard.
