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.

Restrictive covenants are a “list of obligations that purchasers of property must assume … For the first half of the 20th century, one commonplace commitment was a promise never to sell or rent to an African American”. [1] These covenants gained popularity after the Supreme Court’s 1917 decision in Buchanan v. Warley.
Rothstein’s book The Color of Law mentions examples from Brookline, MA; Arlington, MA has examples of it’s own. We’ll look at one from an East Arlington deed dating to 1923. Credit to Christopher Sacca for finding these documents.
First, a land plan to establish content. Below is the subdivision plan for a farm owned by Herbert and Margaret Allen. I count a little over 200 lots in this subdivision. The plan itself states that “no single house shall cost less than $6,000 and no double house shall
cost less than $8,000″. This language also appears in the property deed.

One of the deeds from these parcels appears in book 4631 page 218 and book 4631 page 219, in the Southern Middlesex registry of deeds.
Here’s page 218; the deed begins at the bottom.

Here’s page 219. The racial covenant appears halfway down the page. It reads “No sale or lease of any said lots shall be made to colored people, no any dwelling on any said lots be sold or occupied by colored people”.

The 1920’s were a time of significant residential growth in Arlington, as farmers (called “Market Gardeners” at the time) subdivided and sold off their land. This example shows that Arlington, MA landowners employed some of the same discriminatory tactics for segregation as other communities in the United States. It would take further research to determine how common the use of such covenants was early twentieth-century Arlington.

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.

In 2015 Town Meeting approved the Master Plan. Following is the Housing chapter of that plan. It contains a great deal of information about details of the housing situation in Arlington, challenges of housing price increases, needs for specialty housing, opportunities for meeting these needs, etc. The authors found that “most cities and towns around Arlington experienced a significant rise in housing values from 2000 to 2010. A 40 percent increase in the median value was fairly common. However, Arlington experienced more dramatic growth in housing values than any community in the immediate area, except Somerville. In fact, Arlington’s home values almost doubled.” This and related data helps explain why the need for affordable housing is now so acute.
State Senator Cindy F. Friedman has written a letter to Town Meeting Members supporting Warrant Article 12 and a meaningful MBTA Communities Plan. She writes:
We all want Arlington and Massachusetts to remain welcoming, accessible places to live. In addition to our deficit of housing, I recognize the importance of encouraging smaller, more sustainable housing in walkable areas. Arlington’s Warrant Article 12 will provide a meaningful framework for making progress in these areas. The problems we are experiencing now —out of reach housing prices for new construction and existing homes — exacerbate the crisis and are seriously threatening the economic vibrancy of our communities.

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.

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.

I’m a member of the Affordable Housing Trust Fund Board and an attorney with over 15 years of practice in affordable housing law. Views expressed are my own, not those of the Trust.
The Town of Arlington and the Arlington Affordable Housing Trust Fund have created the Acquisition, Creation and Conversion (ACC) Program to provide a flexible source of funding for creating deed-restricted affordable housing in Arlington. Up to $250,000 is available per restricted unit, and the Town has dedicated federal ARPA funds to support the ACC Program.
ACC Program funds can be used to build new deed-restricted affordable units, whether rented or owned. ACC funds can only be used for existing units if the current tenants will not be displaced.
“Deed-Restricted” Is Important
“Deed-restricted” is the key component here. Housing that is “deed-restricted” as affordable housing is protected by a legally binding agreement that is recorded against the property in the registry of deeds. This agreement specifies the levels of affordability that must be maintained and for how long. It’s a public commitment to provide affordable housing that binds the current owner of the property as well as anyone else who buys the property while the restriction is in place. The ACC Program requires affordability for at least 20 years for rental units and in perpetuity for homeownership units. For rental properties, this means that tenants know that their units will remain affordable for the long term, even if their landlord changes.
Personally, I’m most excited about the potential to use the ACC Program to apply these protections to existing naturally occurring affordable housing in Arlington. For example, if an owner of an existing apartment building participates in the ACC Program, some or all of the apartment units will become deed-restricted affordable housing. Because ACC Program funds can only be used if the existing tenants aren’t displaced, this locks in deed-restricted affordability for the existing tenants. This innovative feature of the program is rare in my experience of affordable housing programs, and it has RFP potential to make meaningful change for existing tenants of naturally occurring affordable housing.
Get the Full Rules
In addition, the ACC Program can be combined with other funding sources, so there is great opportunity for owners to propose their own solutions. The Request for Proposals (RFP) issued for the ACC Program, available here, provides the full rules for participating in the program.
I’ve had an annual ritual for the past several years: obtain a spreadsheet of property assessments from the Town Assessor, load them in to a database, and run a series of R computations against the data. I started doing this for a number of reasons: to understand what was built where (our zoning laws have changed over time, and there are numerous non-conforming uses), the relationship between land and building values, the capital costs of different types of housing, and how these factors have changed over time.
I’d typically compile these analyses into a fact-book of sorts, and email it around to people that I thought might be interested. This year, I’m going to post the analyses here as a series of articles. This first installment contains basic information about Arlington’s low-density housing: single-, two-, and three-family homes, as well as condominiums. Condominiums are something of an oddball in this category — a condominium can be half of a two-family structure, part of a larger residential building, or somewhere in between. There’s a lot of variety.
Here’s a table showing how the number of units has changed over time, since 2013.
land use | 2013 | 2014 | 2015 | 2016 | 2017 | 2018 | 2019 | 2020 |
---|---|---|---|---|---|---|---|---|
Single Family | 7984 | 7983 | 7991 | 8000 | 7994 | 7994 | 7998 | 7999 |
Condominium | 3242 | 3304 | 3367 | 3492 | 3552 | 3662 | 3726 | 3827 |
Two-family | 2352 | 2332 | 2308 | 2282 | 2263 | 2218 | 2183 | 2139 |
Three-family | 207 | 201 | 196 | 194 | 193 | 190 | 185 | 182 |
Arlington’s predominant form of housing — the single family home — has stayed relatively static; we’ve added 15 over the last seven years. The number of condominiums has increased significantly: +585 over seven years. That, coupled with the reduction of two-family homes (-213) and three-family homes (-25) leads me to believe that a fair number of rental units have been removed from the market.
Next, I’d like to look at how these homes are spread across our various zoning districts. (The “Notes” section at the bottom of the post explains what the zoning district codes mean).
Zone | Single-Family | Condo | Two-family | Three-family |
---|---|---|---|---|
B1 | 8 | 22 | 13 | 11 |
B2 | 1 | 4 | 1 | |
B2A | 1 | 18 | ||
B3 | 59 | 4 | ||
B4 | 1 | 59 | 5 | 5 |
B5 | 1 | 1 | ||
I | 8 | 18 | 7 | 1 |
R0 | 502 | |||
R1 | 6798 | 168 | 200 | 7 |
R2 | 647 | 1816 | 1881 | 124 |
R3 | 4 | 39 | 11 | 17 |
R4 | 23 | 79 | 2 | 3 |
R5 | 3 | 616 | 5 | 4 |
R6 | 2 | 686 | 8 | 7 |
R7 | 1 | 243 | 2 | 1 |
A few points to note:
- R0 is our newest district, which was established in 1991. It consists only of conforming single-family homes.
- R1 is Arlington’s original (per 1975 zoning) single-family district. It’s predominantly single-family homes, but there are a fair number of two-family homes, and even a few three-families. The presence of condominiums suggests additional multi-family homes (that consist of two or more condominiums)
- R2 is predominantly two-, and three-family homes. Although three-family homes are no longer allowed in this district, R2 has the largest number of three-families in town.
- Residential uses are no longer allowed in the industrial (I) districts, but the I districts contain 34 homes. These buildings pre-date the current zoning laws (aka “pre-existing non-conforming”). A good portion of the Dudley street industrial district is a residential neighborhood.
I’m pointing out these conformities (and non-conformities) for a reason. The zoning map (and use tables) dictate what is allowed today, along with specifying a vision for the future. Our zoning bylaw happens to contain a strong statement to this effect: “It is the purpose of this Bylaw to discourage the perpetuity of nonconforming uses and structures whenever possible” (section 8.1.1(A)). Despite the strong statement of intent, it can take decades (if not generations) for a built environment to catch up with the bylaw’s prescriptions.
I’ll finish this post with a breakdown of how condominiums are distributed across the various zoning districts:
Zone | 2013 | 2014 | 2015 | 2016 | 2017 | 2018 | 2019 | 2020 | delta |
---|---|---|---|---|---|---|---|---|---|
(N/A) | 14 | 15 | 0 | 0 | 0 | 0 | 0 | 0 | -14 |
B1 | 16 | 16 | 18 | 18 | 18 | 22 | 22 | 22 | 6 |
B2 | 2 | 2 | 2 | 2 | 4 | 4 | 4 | 4 | 2 |
B2A | 19 | 18 | 18 | 18 | 18 | 18 | 18 | 18 | -1 |
B3 | 55 | 55 | 61 | 59 | 59 | 59 | 59 | 59 | 4 |
B4 | 47 | 47 | 59 | 59 | 59 | 59 | 59 | 59 | 12 |
I | 18 | 18 | 18 | 18 | 18 | 18 | 18 | 18 | 0 |
R1 | 140 | 144 | 146 | 148 | 150 | 154 | 162 | 168 | 28 |
R2 | 1355 | 1406 | 1456 | 1518 | 1574 | 1670 | 1723 | 1816 | 461 |
R3 | 22 | 25 | 28 | 31 | 31 | 37 | 37 | 39 | 17 |
R4 | 65 | 67 | 67 | 79 | 79 | 79 | 79 | 79 | 14 |
R5 | 616 | 616 | 616 | 616 | 616 | 616 | 616 | 616 | 0 |
R6 | 630 | 632 | 635 | 683 | 683 | 683 | 686 | 686 | 56 |
R7 | 243 | 243 | 243 | 243 | 243 | 243 | 243 | 243 | 0 |
The last column (“delta”) shows the difference between 2013 and 2020. The largest increase occurred in the R2 (two-family) district, followed by R6 (medium-density apartments, where most of the increase took place in 2014) and R1 (single-family).
That it will do it for the first installation. In the next post, we’ll look at how the cost (assessed values, actually) of Arlington’s low density housing has changed over the last seven years.
Here is a spreadsheet, containing the various tables shown in this article.
Notes
Arlington’s zoning map divides the town into a set of districts, and each district has regulations about what kinds of buildings and uses are allowed (or not allowed). The districts mentioned in this article are:
- B1 (Neighborhood Office district)
- B2 (Neighborhood Business distrct)
- B2A (Major Business District)
- B3 (Village Business District)
- B4 (Vehicular-Oriented Business District)
- I (Industrial District)
- R0 (Single-Family, large-lot district)
- R1 (Single-Family Distict)
- R2 (Two-Family District)
- R3 (Three-Family District)
- R4 (Townhouse District)
- R5 (Low-Density Apartment District)
- R6 (Medium-Density Apartment District)
- R7 (High-Density Apartment District)
Arlington’s Zoning Bylaw describes each district in detail (see sections 5.4.2, 5.5.2, and 5.6.2)
