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.

As the public hearings on the zoning articles proceeded in late winter and early spring, 2019, it became clear that there was a very strong sentiment that the proposed increase in density in these designated zoning districts should result in an increase in affordable housing in Arlington. This coincided with the approved 2015 Master Plan’s stated goals:
- Encourage mixed-use development that includes affordable housing, primarily in well-established commercial areas.
- Provide a variety of housing options for a range of incomes, ages, family sizes, and needs.
- Preserve the “streetcar suburb” character of Arlington’s residential neighborhoods.
- Encourage sustainable construction and renovation of new and existing structures (see ch. 5, pg 77++ for housing section)
- The Yes on 16 report supports the citizen initiated petition resulting in Article 16 and demonstrates the tremendous impact of rapidly increasing land values on the overall affordability of property in Arlington. Building a stack of homes on one footprint is far more financially affordable than creating a single home on the same footprint of land.
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.

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.

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.

As Arlington considers new zoning and other policy decisions to increase the amount of affordable housing in the town, a concern has been raised about the threat of greater costs to the Town’s budget from new people with school age children moving into the town. The concern: additional children in the public schools costs the town more than the additional new property tax revenue the Town collects from the new housing.
This post examines this concern, drawing on data from two recent housing developments, representing 283 units of housing in Arlington, to determine that actually the Town budget gains over 4.5 times the actual cost of paying for the students. According to the most recent 2020 tax bills, the Town expects to collect $1,250,370 in revenue and to spend an additional $269,589 for the new Arlington Public School students living in these developments.
The data suggests that the fear of increased school costs, overwhelming the potential new revenue from new housing construction is not warranted.

Interview with Aaron Clausen, AICP; City of Beverly, Director, Planning and Community Development
Rather than express generalized worry about the “lack of affordable housing”, Peabody, Salem and Beverly have created an intermunicipal Memorandum of Mnderstanding (MOU) to very specifically define and target the problem and the population they want to address.
According to Aaron Clausen, “There is a fair amount of context that goes along with the MOU, but primarily the communities got together as sort of a coalition to survey and understand what was going on relative to homelessness. What came out of that is a recognition that there is not enough affordable housing generally, and particularly transitional housing, or more specifically permanent supportive housing.
“Salem and Beverly both have shelters, however the shelters were basically serving as permanent housing (and running out of space). That won’t help someone into a stable housing situation. Anyway, this was the agreement (attached MOU) and the good news is that it has resulted in affordable housing projects; one is done in Salem for individuals and Beverly has a 75 unit family housing project permitted and seeking funding that has a set aside for families either homeless or in danger of becoming homeless.
“There is also a redevelopment of a YMCA in downtown Beverly that will increase the number of Single Room Occupancy units. I wouldn’t say that the MOU got it done by itself but it helps demonstrate a regional approach. ”

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.
This is the second in a series of “Arlington 2020” articles. The first article looked at the number of one-, two-, and three-family homes and condominiums in Arlington, and how that housing stock has changed over time. This article will examine changes in the value of those properties. We’re going to look at “value” through the lens of property assessments, so we should start with an explanation of what property assessments are and how they’re used.
A property assessment is simply the Town Assessor’s best estimate of what a property is worth, based on market values. The assessor’s office inspects properties every ten years; during intervening years, assessments are adjusted based on sale prices of similar homes in a given tax neighborhood. For all practical purposes, assessed values tend to trail market values by two years. In my neighborhood, property assessments are spot on — my house was assessed at $501,000 in 2020; during 2018, sales of similar homes in the neighborhood ranged from $495,000 to $520,000.
Condominiums have a single assessed value, which includes land and buildings. Otherwise, assessed values are broken down into land value, building value, and yard items (e.g., a garage or a shed).
Assessed values are used to determine the tax rate. The assessors page on the town website has calculations in worksheet form, but for all practical purposes, it’s just a division problem. One takes the total tax levy and divides by the sum of all property assessments (in thousands of dollars), and that’s the tax rate. An individual’s taxes are the assessed value of their property (in thousands of dollars) multiplied by the tax rate. If an individual owns (say) 1% of the assessed value in town, that individual will pay 1% of the property tax levy.
The main point is that assessed values are based on market values, but with a two-year lag. Consequently, we can use them as a way to see how home prices have changed over time.
With that background information out of the way, we can look at some numbers. Here’s a graph of the median assessed values for condominiums, one-family, two-family, and three-family homes from 2013 through 2020. (the “median” is a value such that half of the assessments are above, and half are below).

year | Condominium | Single Family | Two-family | Three-family |
2013 | $297,800 | $472,850 | $532,650 | $581,600 |
2014 | $300,150 | $484,400 | $530,000 | $574,800 |
2015 | $318,200 | $507,900 | $572,000 | $616,300 |
2016 | $351,050 | $546,300 | $623,150 | $673,550 |
2017 | $357,750 | $581,200 | $663,900 | $714,800 |
2018 | $395,400 | $618,800 | $732,100 | $787,600 |
2019 | $463,250 | $701,550 | $851,200 | $897,500 |
2020 | $473,100 | $771,900 | $944,000 | $1,010,850 |
%change | 58.87% | 63.24% | 77.23% | 73.81% |
As one would expect, two-family homes are worth more than single-family, and three-family are worth more than two. Condominiums have a lot of variety; they could be half of a duplex, or a single unit in an apartment building. But a general upward trend is clearly evident.
These values are straight out of the assessor’s database, and not adjusted for inflation. The Bureau of Labor Statistic’s inflation calculator shows 12% inflation between 2013 and 2020; the %change is pretty considerable, even if one deducts 12% for inflation.
Next, I’d like to dig further into the 1–3 family assessments, by breaking them down into the value of land vs the value of buildings, and showing how that’s changed over time.
Single-family homes:

year | Land value | Building value | Total assessed value |
2013 | $243,700 | $226,300 | $472,850 |
2014 | $253,750 | $227,050 | $484,450 |
2015 | $272,700 | $229,900 | $507,900 |
2016 | $296,400 | $243,950 | $546,400 |
2017 | $326,400 | $246,400 | $581,250 |
2018 | $360,900 | $248,100 | $618,800 |
2019 | $440,400 | $250,400 | $701,600 |
2020 | $448,600 | $316,300 | $771,900 |
%change | 84.08% | 39.77% | 63.24% |
Two-family homes:

year | Land value | Building value | Total assessed value |
2013 | $202,500 | $320,550 | $532,650 |
2014 | $212,250 | $307,800 | $530,000 |
2015 | $256,400 | $309,800 | $572,000 |
2016 | $262,500 | $349,400 | $623,150 |
2017 | $307,000 | $350,700 | $663,900 |
2018 | $352,500 | $373,900 | $732,100 |
2019 | $478,300 | $374,850 | $851,700 |
2020 | $454,500 | $486,100 | $944,000 |
%change | 124.44% | 51.65% | 77.23% |
Three-family homes:

year | Land value | Building value | Total assessed value |
2013 | $200,100 | $377,900 | $581,600 |
2014 | $209,100 | $364,100 | $574,800 |
2015 | $249,800 | $366,550 | $616,300 |
2016 | $259,950 | $412,350 | $673,550 |
2017 | $298,100 | $412,500 | $714,800 |
2018 | $343,050 | $438,800 | $787,600 |
2019 | $459,000 | $440,100 | $897,500 |
2020 | $440,100 | $578,450 | $1,010,850 |
%change | 119.94% | 53.07% | 73.81% |
There are several things worth pointing out in these breakdowns.
First, note that the land and building values “jump” a bit between 2019–2020. 2020 was one of our full reassessment years, so I’m willing to attribute this to a periodic course correction. The total increase is generally linear, but the land/building composition has changed.
Second, the median land value for single-family homes is higher than the median building value, for all years between 2013–2020.
Third, most of the increases come from changes in land value. I believe this comes down to location, location, and location. Arlington has a well-respected public school system, and it’s close to universities and tech centers is Cambridge and Boston, and office parks in Lexington, Waltham, and Burlington. City amenities are close at hand.
So what does one do about our rising home prices, and in particular, the rising value of land? The first (and perhaps default) answer is to do nothing. Rising property values are a boon to homeowners who purchased a capital asset (i.e., a house) in the past, and have seen its value appreciate over time. The downside of doing nothing is that each year, increasing housing prices create an ever-increasing income threshold for new residents.
An alternative approach would be to allow more (and smaller) units to be built on each lot. This requires reconstruction or redevelopment, but it allows the cost of land to be amortized among several households. More units/lot means more people and more density, but it reduces the income threshold for buying in to Arlington. (Note that the per-unit cost for three-family homes is lower than the per-unit cost for two-family homes. Similarly, the per-unit cost for two-family homes is lower than the cost of a single-family home).
A third article will look at the distribution of housing prices in Arlington, and how the distribution varies by housing type.
Here is a spreadsheet of data shown in this post.
