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.

In a 2019 study, MAPC found that:
- Three out of ten spaces sit empty during peak demand
- The key factors that drive parking demand are parking supply, transit accessibility and the percentage of deed-restricted units
This study raises important questions about the wisdom of continuing to commit large sections of the land area of our municipalities to be on reserve for parking cars. Such extra space could be used to benefit the open space, environmental sustainability and the need for more housing.

The term “AMI” or “Area Median Income” comes up in almost any discussion about affordable housing, because it’s used to set rents and the household incomes for people who are eligible to live in affordable dwellings. AMI is a fairly technocratic concept and my goal is to make the concept (and the numbers) easier to understand.
AMIs are set each year by the U.S. Department of Housing and Urban Development; broadly speaking, an AMI is the median income of a region. Arlington is part of the “Boston-Cambridge-Quincy, MA-NH HUD Metro FMR Area” which consists of more than 100 cities and towns in Massachusetts and New Hampshire. Median incomes represent the “middle” family income of an area—half of households make more, and half make less.
In the process of turning median incomes into income limits, HUD also considers household size: larger households are assigned larger AMI limits than smaller ones, in order to reflect the higher cost of living for more family members.
How do these limits translate into affordable housing regulations? Arlington’s affordable housing requirements (aka “inclusionary zoning”) require that rents for affordable units be priced for the 60% area median income, but the dwellings are available to households making up to 70%. Let’s show an example with some numbers.
| Household size | 60% Income Limit | 70% Income Limit | 60% Rent |
|---|---|---|---|
| 1 | $68,520 | $79,940 | $1,717/month |
| 2 | $78,360 | $91,420 | $1,959/month |
| 3 | $88,140 | $102,830 | $2,203/month |
HUD considers an apartment suitable for a household if it has one bedroom less than the number of household members, so a two-bedroom apartment would be suitable for a household of three, a one-bedroom would be suitable for a household of two, and a studio would be suitable for a household of one. The monthly rent for a two-bedroom apartment would be calculated as follows: $88,140 ÷ 12 × 30% = $2,203. The 30% comes from HUD’s rule that affordable housing tenants should not be cost-burdened, meaning that they pay no more than 30% of their income in rent.$88k or $102k/year can seem like a lot of money (and once upon a time it was). To get a better sense of what these income levels mean, I looked into what kinds of jobs pay these wages. To that end, I found wage information from the Arlington Public Schools report to Town Meeting, the Arlington town budget, and wage data from the Bureau of Labor Statistics. Here are a few scenarios:
Scenario 1: single adult
Scenario 1 represents a single adult living alone, and earning between $68,520 and $79,940. Jobs in this pay range include:
- Elementary classroom teacher ($62,000 – $75,000)
- Town planner ($75,000 – 79,000)
- Animal Control Officer ($72,000)
- Firefighter ($73,640)
- Librarian ($70,395)
- Lab Technician ($70,710)
- Social Worker ($71,470)
- Subway operator ($72,270)
- Licensed Practical Nurse ($75,690)
- Paralegal ($77,500)
- Chef ($78,040)
- Carpenter ($78,000)
Scenario 2: single parent with household of two
Scenario 2 represents a single parent earning between $78,360 and $91,420/year. Jobs in this pay range include:
- Office Manager – Assessor’s office ($80,399)
- Assistant Town Clerk ($77,375)
- Town Engineer ($74,000 – $80,000)
- Police Department Patrol Officer ($87,000)
- Town Budget Director ($88,488)
- Telecommunications equipment installer ($80,350)
- Plasterer and Stucco Mason ($82,250)
- Electrician ($82,380)
- Cement Mason ($86,250)
- Plumber and pipe fitter ($90,580)
Scenario 3: household of two, both adults
Scenario 3 has two adults, each earning $39,180 – $45,710 per year. Jobs in this salary range include several that we’ve come to know as “essential workers” during the pandemic.
- Special education teaching assistant ($34,290)
- Arlington Public Schools Paraprofessional ($36,290 – 42,440)
- Substitute Teacher ($34,921)
- Inspectional Services Record Keeper ($44,481)
- Food preparation worker ($39,590)
- Bartender ($39,730)
- Childcare worker ($40,470)
- Ambulance Driver ($40,890)
- Waiter ($41,440)
- Pharmacy aide ($41,460)
- Bank teller ($42,270)
- Tailor and dressmaker ($43,790)
- Restaurant cook ($44,140)
You may have noticed gaps in these lists — for example, there are no jobs listed in the $50,000 – $60,000 range because it’s in between the income limits for one- and two-income households. It’s also worth noting that a fair number of town employees’ salaries would qualify them for affordable housing (the town is Arlington’s largest employer).
So who qualifies to live in affordable housing? People with a lot of ordinary, working-class jobs, including many town employees.
This timely report on the question of affordable housing vs. density comes from the California Dept. of Housing & Community Development and mirrors the situation in the region surrounding Arlington MA.
Housing production has not kept up with job and household growth. The location and type of new housing does not meet the needs of many new house- holds. As a result, only one in five households can afford a typical home, overcrowding doubled in the 1990’s, and too many households pay more than they can afford for their housing.
Myth #1
High-density housing is affordable housing; affordable
housing is high-density housing.
Fact #1
Not all high density housing is affordable to low-income families.
Myth #2
High-density and affordable housing will cause too much traffic.
Fact #2
People who live in affordable housing own fewer cars and
drive less.
Myth #3
High-density development strains public services and
infrastructure.
Fact #3
Compact development offers greater efficiency in use of
public services and infrastructure.
Myth #4
People who live in high-density and affordable housing
won’t fit into my neighborhood.
Fact #4
People who need affordable housing already live and work
in your community.
Myth #5
Affordable housing reduces property values.
Fact #5
No study in California has ever shown that affordable
housing developments reduce property values.
Myth #6
Residents of affordable housing move too often to be stable
community members.
Fact #6
When rents are guaranteed to remain stable, tenants
move less often.
Myth #7
High-density and affordable housing undermine community
character.
Fact #7
New affordable and high-density housing can always be
designed to fit into existing communities.
Myth #8
High-density and affordable housing increase crime.
Fact #8
The design and use of public spaces has a far more
significant affect on crime than density or income levels.
See an example of a “case study” of two affordable housing developments in Irvine CA, San Marcos at 64 units per acre.

San Paulo at 25 units per acre.

Both are designed to blend with nearby homes.
A report by Mass Housing Partnership’s Shelly Goehring looks at Arlington’s housing development history and policies to understand how municipal action and inaction can contribute to housing inaffordability and can limit the population diversity within a community. The report implies that it has been difficult historically for reputable housing developers to work with the regulatory structure within Arlington to get housing built.
Massachusetts has the nation’s 2nd largest gap in homeownership between households of color (31% own homes) and white households (69% own homes).

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)
Article 16 is a proposal to encourage the production of affordable housing in the town of Arlington. I brought this article to town meeting for several reasons, namely, our increasing cost of housing and our increasing cost of land. Arlington is part of the Metropolitan Boston area; we share borders with Cambridge, Somerville, and Medford, and are a mere 5.5 miles from Boston itself. Years ago, people moved out of cities and into the suburbs. That trend has reversed during the last decade, and people are moving back to urban areas, including Metro-Boston. Metro-Boston is a good source of jobs; people come here to work and want to live nearby. That obviously puts pressure on housing prices, and Arlington is not immune from that pressure.
Another reason for proposing Article 16 was my desire to start a conversation about the role our zoning laws play in the cost of housing, and how they might be used to relieve some of that burden. During the 20th century people discovered that one cannot draw a line on a map and say “upper-class households on this side, lower-class households on that side”, but one can draw a line on a map and say “single-family homes on this side, and apartments on that side”. For all practical purposes, the latter achieves the same result as the former. When zoning places a threshold on the cost of housing, it determines who can and cannot afford to live in a given area.
Today 70% of Arlington’s land is exclusively zoned for single family homes, the predominant form of housing in town. In 2013, the median cost of a single-family home was $472,850; this rose to $618,800 in 2018 — an increase of 31%. We can break this down further. The median building cost for a single-family building rose from $226,300 in 2013 to $248,100 in 2018 (an increase of 9.6%), and the median cost for a single-family lot rose from $243,700 to $360,900 (an increase of 48%). Land is a large component of our housing costs, and it continues to rise. Certain neighborhoods (e.g., Kelwyn Manor) saw substantial increases in land assessments in 2019, enough that the Assessor’s office issued a statement to explain the property tax increases. To that end, multifamily housing is a straightforward way to reduce the land costs associated with housing. Putting two units on a lot instead of one decreases the land cost by 50% for each unit.
Article 16 tries to encourage the production of affordable housing (restricted to 60% of the area median income for rentable units and 70% for owner-occupied units). It works as follows:
- Projects of six or more units must make 15% of those units affordable. This is part of our existing bylaws.
- Projects of twenty or more units must make 20% of those units affordable. This is a new provision in Article 16.
- Projects of six or more units that produce more than the required number of affordable units will be eligible for density bonuses, according to the proposed section 8.2.4(C). Essentially, this allows a developer to build a larger building, in exchange for creating more affordable housing.
- Projects of six or more units that produce only the required number of affordable units are not eligible for the density bonuses contained in 8.2.4(C).
- Projects of 4-5 units will be eligible for the density bonuses in section 8.2.4(C), as long as they are of a use, and in a zone contained in those tables. This provision is intended to permit smaller apartments and townhouses, filling a need for residents who don’t necessarily want (or may not be able to afford) a single-family home. This provision can help reduce land costs by allowing a four-unit townhouse in place of a duplex, for example.
Historically, Arlington has had mixed results with affordable housing production, mainly due to the limited opportunity to build projects of six units or more. It is my hope that the density bonuses allow more of these projects to be built.
In conclusion, the problem of housing affordability in Arlington comes from a variety of pressures, is several years in the making, and will likely take years to address. I see Article 16 as the first step down a long road, and I ask for your support during the 2019 Town Meeting. I’d also ask for your support on articles 6, 7, and 8 which contain minor changes to make Article 16 work properly.
Welcome to the redesigned Equitable Arlington website! We know that Arlington values openness and diversity, a greener future, and vibrant neighborhoods and downtowns—but our current zoning is holding us back. We’re advocating for change because we recognize that the choices we make on zoning and housing policy are key to living those values. We are committed to strengthening our community through respectful dialogue and by listening to our neighbors. Our aim with this site redesign is to share accurate and relevant information to help inform such conversations.

With this redesigned site we have:
- Answered some of the most common questions that have come up in our conversations with other residents.
- Created a zoning dictionary with explanations of many of the terms that pepper zoning discussions.
- Gathered a list of resources, where you’ll find everything from short explainer videos to detailed research
- Developed a history of zoning timeline that shows how Arlington’s history fits into the larger context of government actions.
If you’re not familiar with us, I hope you’ll take a minute to read our mission and why our work matters. I also hope you’ll scroll through to meet us, see some of our smiling faces, and read in our own words why we do this work. We’re renters and homeowners, long time residents and newcomers to town who come to this work with a variety of viewpoints and lived experiences!
We believe Arlington can be a leader in the greater Boston area by the choices we make to create more equitable housing policy. Our local actions have effects that go beyond our borders. Arlington has recognized our power to make an impact and has been a regional leader on many issues.
We can channel this same energy and our values to make sure Arlington has the vibrant sustainable and equitable future we all want. To succeed, we need engaged residents who understand the issues, who can balance competing interests, and who are willing to do the necessary hard work. Please join us in building a more equitable Arlington!

Article 1 in a series on the Arlington, MA master planning process. Prepared by Barbara Thornton
Arlington, located about 15 miles north west of Boston, is now developing a master plan that will reflect the visions and expectations of the community and will provide enabling steps for the community to move toward this vision over the next decade or two. Initial studies have been done, public meetings have been held. The Town will begin in January 2015 to pull together the vision for its future as written in a new Master Plan.
In developing a new master plan, the Town of Arlington follows in the footsteps laid down thousands of years ago when Greeks, Romans and other civilizations determined the best layout for a city before they started to build. In more recent times, William Penn laid out his utopian view of Philadelphia with a gridiron street pattern and public squares in 1682. Major Pierre Charles L’Enfant developed the hub and spoke street plan for Washington DC in 1798. City planning started with new cities, relatively empty land and a “master builder” typically an architect, engineer or landscape architect commissioned by the land holders to develop a visionary design.
In the 1900’s era of Progressive government in America, citizens sought ways to reach a consensus on how their existing cities should evolve. State and federal laws passed to help guide this process, seeing land use decisions as more than just a private landowner’s right but rather a process that involved improving the health and wellbeing of the entire community. While the focus on master planning was and still is primarily physical, 21st century master planners are typically convened by the local municipality, work with the help of trained planners and architects and rely heavily on the knowledge and participation of their citizenry to reflect a future vision of the health and wellbeing of the community. This vision is crafted into a Master Plan. In Arlington the process is guided by Carol Kowalski, Director of Planning and Community Development, with professional support from RKG Associates, a company of planners and architects and with the vision of the Master Planning advisory committee, co-chaired by Carol Svenson and Charles Kalauskas, Arlington residents, and by the citizens who share their concerns and hopes with the process as it evolves. This happens through public meetings, letters, email, and surveys. The most recent survey asks residents to respond on transportation modes and commuting patterns
We all do planning. Starting a family, a business or a career, we lay out our goals and assume the steps necessary to accomplish these goals and we periodically revise them as necessary. The same thing is true for cities. Based on changes in population, economic development, etc. cities, from time to time, need to revise their plans. In Massachusetts the enabling acts for planning and zoning are here http://www.mass.gov/hed/community/planning/zoning-resources.html. The specific law for Massachusetts is MGL Ch. 41 sect. 81D. This plan, whether called a city plan, master plan, general plan, comprehensive plan or development plan, has some constant characteristics independent of the specific municipality: focus on the built environment, long range view (10-20 years), covers the entire municipality, reflects the municipality’s vision of its future, and how this future is to be achieved. Typically it is broken out into a number of chapters or “elements” reflecting the situation as it is, the data showing the potential opportunities and concerns and recommendations for how to maximize the desired opportunities and minimize the concerns for each element.
Since beginning the master planning process in October, 2012, Arlington has had a number of community meetings (see http://vod.acmi.tv/category/government/arlingtons-master-plan/ ) gathering ideas from citizens, sharing data collected by planners and architects and moving toward a sense of what the future of Arlington should look like. The major elements of Arlington’s plan include these elements:
