(DRAFT – 7/11/2019)

Arlington Planning Department officials report on options for the Town to mitigate the effects of housing demolitions and housing replacements in neighborhoods.
Evidence suggests that lack of appropriate regulatory policies have led to incidences of “mcmansions” and other issues that concern neighborhood residents. This study looks at the data, the policy and regulatory options for Arlington. It also looks at how comparable nearby communities have managed similar circumstances.
This 42 page report covers a great deal of data and analysis of homes by zoning district, gaps in the effectiveness of the current regulatory structure, affects on affordability in Arlington by zoning district, information on housing prices and sales, etc.
“Best practices” include descriptions of demolition delay, expansion of local historic districts, neighborhood conservation districts, design review standards and guidelines and possible revisions to the regulatory framework in Arlington. The report also includes interesting case examples of how comparable communities near Arlington handle these issues.
This report was presented to the Arlington Select Board on July 22.
Read the complete report and see the available data and tables.
Arlington is in the process of update the town’s 2016 Housing Production Plan, and the Housing Plan Implementation Committee and Planning Department have put together a “meeting in a box” as part of their outreach efforts. The idea is to package a set of discussion questions and supplementary materials, so that groups can talk through the questions on their own and provide written feedback. Meeting in a box materials are available from the town website.
I tried this with a group of friends. Here are the questions, and points that came up during the group discussion. Notes that these are discussion notes (transcribed from large sheets of easel paper), and don’t represent agreement or concensus.
Question 1: Housing Needs. Arlington residents have expressed concerns about the housing needs of older adults. Other needs identified so far are the cost and condition of rental housing, the impact of Arlington’s housing sale prices on the ability of young families to find a home in Arlington they can afford, and the impact of limited housing choices on racial and ethnic diversity in Arlington. What housing needs are you most concerned about?
Question 2: Challenges to Meeting Affordable Housing Needs. Participants in interviews conducted for the Housing Plan and at the June 9 Housing Plan Meeting were asked about challenges or obstacles to providing affordable housing in Arlington. Several challenges were identified, such as difficulty finding locations that for new housing development or redevelopment, how the Town’s Housing Trust Fund and CPA funds should be used to meet housing needs, and general tensions and disagreement about growth in Arlington that make it hard for people to agree. What challenges do you think are the biggest impediments to meeting housing needs in Arlington?
Question 3: Opportunities for Reaching Agreement. What steps would help to bring Arlington residents together about providing affordable housing? How can the Town balance concerns about housing needs and natural resources protection? Or concerns about housing need and preserving Arlington’s built environment? What do you think most could people agree on?
As you can see, our group had a range of opinions and even a few points of disagreement – for example, “there’s an unwillingness to accept incremental progress” vs “many incremental changes feel too big”. I feel like that pair is a good illustration of how different people have different comfort zones; a situation that can be challenging to navigate. Metro Boston is growing, as are metropolitan areas all across the country. Our new arrivals will need places to live, and I’d hope to see Arlington be proactive in addressing that need.
Report by Vicki Been, Ingrid Gould Ellen, and Katherine O’Regan, Supply Skepticism: Housing Supply and Affordability, NYU Furman Center 8/20/18
Some affordable housing advocates question the premise that increasing the supply of market-rate housing will result in more affordable housing. This paper addresses the key arguments these “supply skeptics” make. Considering both theory and empirical evidence, the authors conclude that adding new market-rate homes moderates price increases does make housing more affordable to low- and moderate-income families.
At the outset, the authors review the relevant studies and conclude that “the preponderance of the evidence shows that restricting supply increases housing prices and that adding supply would help to make housing more affordable.” They then turn to several arguments the supply skeptics make. One key issue is whether adding housing in a part of the housing market will affect prices in another. The housing market is not uniform but composed of various submarkets. These submarkets relate to each other in complex ways. Critically, however, if demand forces up prices in a higher-end submarket, some buyers will turn to the next segment down and bid up prices there, generating a cascade. Adding supply at higher levels reduces this cascade and relieves price pressure all the way down. Empirical research indicates that this “filtering” process happens surprisingly quickly.
Supply skeptics may also fear that construction of new housing will exacerbate affordability problems by raising neighborhood rents or prices, fueling gentrification, and potentially displacing existing residents. New construction can have both positive and negative effects on prices or rents of nearby homes. New housing may an amenity that makes a neighborhood more attractive – and expensive. But it also absorbs demand and may reduce the incentive to upgrade existing housing to please high-end buyers. The evidence on the net effect of these effects is unclear. An important California study indicates that the production of market rate housing was associated with a lower probability that low-income residents in the neighborhood would experience displacement. But more research is needed.
The authors point to additional disadvantages of limiting supply, including pushing lower-wage workers to live in distant suburbs, where long commutes add to regional traffic woes and greenhouse gas emissions. They stress, however, that increased supply, while essential, is not sufficient to address the affordability challenge. Government intervention through subsidies and other measures is critical to ensure that housing supply is added at prices affordable to a range of incomes, and especially the lowest ones.
While you’ve heard a lot about the MBTA Communities Plan, you may be surprised to learn that your neighbors might not know about it. If they have heard the name, they might think it has to do with MBTA buses. Or they might have heard rumors giving an incorrect idea of what the plan is.
You may be tempted to tell them to read the full report by the MBTA Communities Plan Working Group [PDF], but most people don’t have the time to study a 51-page report, even if it’s the most gripping read since Gone Girl. Many of them are so busy they may only have ten seconds to spare.
But you’re in luck, because we’ve written up quick talking points you can use if you’re talking to someone for ten seconds, a minute, or two minutes. If they bring up something they’ve heard that seems incorrect, we also have responses so you can clear up that misinformation.
The MBTA Communities law says that communities served by the MBTA need to zone areas for multi-family housing. We need more capacity than the state requires in order to:
The MBTA Communities law says that communities served by the MBTA like Arlington need to zone some areas for multi-family housing. We need more capacity than the state requires to:
Right now, developers can easily build a McMansion. But they have to go through a long and pricey permitting process to build multi-family housing that’s the exact same size. This plan will make it just as easy to build apartment buildings of the same size as that McMansion. And if it’s at least 6 units it will include an affordable unit!
The MBTA Communities Law is a state law. It requires communities with MBTA service to zone some areas for multi-family housing. Each community is required to reach a specific capacity of multi-family housing. Arlington’s current plan goes beyond what the state requires. We need to go above and beyond because:
Use these ONLY if the person brings up these concerns. Listen carefully to what they have to say first, and stick to the top three points.
While it may seem that the process is moving quickly, in fact planning and discussions have been going on for almost a year. The topic was first introduced in a town-wide meeting on November 17, 2022. The Working Group first met in February and has convened 19 times since then. All the Working Group’s meetings were open to the public and attracted a number of attendees. There were also three larger public forums, several surveys, and other outreach outlined on page 5 of the working group’s report. In any case, in order to comply with the law, all communities must submit final plans by the end of 2024. By acting now we get to take advantage of pilot programs and other state benefits.
When the group looked at a “bare minimum” plan (minimum units on maximum acres), they found that in most areas it would not yield additional housing. In some places, it would permit about 2,100 homes in an area that has over 3,000 homes now – in other words, it would allow fewer homes than already exist.
Yes, but the majority were built before 1975. Current zoning and the permitting process make it very difficult for similar buildings to be built today.

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.
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.
(This post originally appeared as a one-page handout, distributed at The State of Zoning for Multi-Family Housing in Greater Boston.)

This chart shows the assessed value of Arlington’s low density housing from 2015–2019 (assessed values generally reflect market values from two years prior). During this time, home values increased between 39% (single-family homes) and 48% (two-family homes). Most of the change comes from the increasing cost of land. As a point of comparison, the US experienced 7.7% inflation during the same period. (1)
Arlington has constructed six apartment buildings in the 44 years since the town’s zoning bylaw was rewritten in 1975; we constructed 75 of them in the preceding 44 years.(2) Like numerous communities in the Metro-Boston area, we’re experiencing a high demand for housing, but our zoning regulations have created a paper wall that prevents more housing — including affordable housing — from being built.
Communities need adequate housing, but they also need housing diversity: different types of housing at different price points. The housing needs of young adults are different than the housing needs of parents with children, which are in turn different than the housing needs of senior citizens. As demographics change, housing needs change too. Keeping people in town means providing them with the opportunity to upsize or downsize when the need arises.
If Arlington’s housing costs had only increased with the rate of inflation, the cost of single family housing would average $581K, over $170K less than today. The median household income in Arlington is about $103K/year.(3) Buying an average single family-home with that income on a typical 30-year mortgage would require approximately 46% of a household’s monthly income.(4)
Either homes in Arlington will only be available to people who have much more substantial incomes than current residents, or the town will find a way to balance the rapidly growing cost of land against the housing needs of its current citizens, those still in school, those preparing to downsize as well as those looking for a bigger space.
In addition, Arlington’s commercial economy will thrive with a greater number of housing units so we can keep the empty nesters, and the new college graduates who have lived in the town for years, as well as welcome new Arlingtonians to support our local businesses, restaurants and other services.
Our Town, like others in the state, is looking for ways to balance the needs of our citizens with the market forces of rising land costs while maintaining a healthy, diverse community.
Footnotes
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:
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.
