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.

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.

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.
For more information, see the full post here.
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:
(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
- The inflation amount comes from Inflation amount from https://data.bls.gov/cgi-bin/cpicalc.pl.
- Figures on multi-family unit construction are taken from Arlington Assessor’s data. They reflect multi-family buildings that are still used as rental apartments.
- Income levels come from 2013-2017 ACS 5-year data for Arlington, MA.
- Assuming 10% downpayment, 4% interest, $800/year for insurance, and Arlington’s $11.26 tax rate, the monthly mortgage payment would be nearly $4000/month.
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.
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.
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.
Data in a Mass Housing Partnership report shows how far behind the Boston metropolitan area has fallen in meeting the housing needs of its citizens. There are four primary categories for measuring the inadequacies: 1. Availability, 2. Affordability, 3. L0cation and Mobility and 4. Equitability. See the full report for more data and examples. Two slides are shown below.
