Many issues are under discussion as a result of these proposed zoning Articles. Issues include: housing affordability, the diversity of housing and incomes in Arlington, environmental concerns and sustainability, tax burdens or tax savings potentially resulting from growth, the risk of postponing the decisions, and the image of Arlington as a community that values diversity and equitability. This one page “fact sheet” attempts to address many of these issues and concerns.
The discussions on zoning have been confusing because while zoning covers ALL of Arlington’s land and the zoning bylaws for all Arlington’s zones are referenced, the key issues of greatest interest to Town Meeting are the discussions about increasing density. These discussions pertain ONLY to those properties currently zoned as R4-R7 and the B (Business) districts. These density related changes would affect only about 7% of Arlington’s land area. The map shows the specific zones that would potentially be affected. They lay along major transportation corridors.

On the evening of Wednesday, June 12th, Equitable Arlington co-hosted with the Town’s Department of Planning and Community Development and Envision Arlington, a ninety-minute webinar entitled “What’s an ADU and How Do I Build One?”
The webinar was designed for anyone interested in learning more about what defines an accessory dwelling unit (ADU) and the ins and outs of constructing one in Arlington on their property. Topics included: the history and rationale behind Arlington’s ADU zoning article; the applicable zoning regulations to understand when building an ADU; considerations and cost estimates for three different types of ADUs; guidance on the permitting process with the Town’s Inspectional Services Department; and two case studies–one by a local homeowner, and a second, by the Housing Corporation of Arlington detailing their experience constructing a 100% electric, 2-bedroom Affordable Housing ADU at 40-42 Dorothy Road.
The webinar was recorded and is available on demand (registration required).
The Town website also has answers to some FAQs: https://www.arlingtonma.gov/departments/inspectional-services/accessory-dwelling-units-adus
The calculation for what is permanently affordable housing is complicated. Arlington’s affordable rate is based on a region that includes the Area Median Income (AMI) of the Cambridge-Boston-Quincy region. The rate is adjusted and reset periodically according to federal HUD guidelines. The rate is applied based on family size and on the Town’s definition of what income level is eligible for Inclusionary Housing opportunities in Arlington. In Arlington a 3 person family would qualify if their income was under 60% of AMI. At this time, that is approximately $58,000 for a family of three.
For more information, see this table of income limits from Cambridge’s Community Development Department, and this short paper on affordable housing from the City of Boston.
(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.

- 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.
The material in this post came from my efforts to learn about when Arlington’s housing was built. The data comes from the town’s 2019 property tax assessments, where I took our nineteen-thousand-and-some-odd homes and apartments and broke them down by housing type and decade built. It’s not exactly a history housing of production, though it is a close approximation. In this analysis, a single-family home built in the 1912 and rebuilt as a two-family in 1976 would show up as two units built in the 1970s. Similarly, a three-family home that was built in the 1924 and later converted to condominiums would show up as three condominiums built in the 1920s.
Here’s the visual summary:

And here’s a small spreadsheet with the underlying numbers.
My first surprise was at how much we built in the 1920s: just under five thousand units. This was our biggest decade for housing production, and nearly double our second biggest (the 1950s). Another surprise was the 1990s; 132 of our homes were constructed during that decade, which is the smallest number since the 1870s.
What about homes constructed before 1850? There are only 117 of them, and they’re omitted from the data set. I’ve also omitted residential units in mixed-use buildings, since my copy of the assessors data doesn’t break mixed-use buildings into residential and non-residential units.
The citizen participation process including presentations, discussions, public hearings, letters and comments has been long and arduous. The issues are complicated and sometimes feelings run high. In such situations, there can be a feeling that citizens have not been heard. This document, “Guide to Zoning Amendments Related to Multifamily Uses and Mixed-Use“, summarizes many of the issues that have been raised and the changes that have been made in the zoning Articles as a result of the citizen participation in the public review process. Citizens have been heard.

When you love the place you live and you want to help it become even better, how can you make a difference? Arlington is an extremely civically active community, with hundreds of residents involved in Town Meeting, several dozen boards and committees, and numerous other groups that play an important role in improving our town. The vast array of options can be a bit dizzying for a newcomer to sort through.
Fortunately, Arlington has recently launched Arlington Civic Academy to provide interested residents with a pathway to becoming more civically literate and involved. Ably organized by Joan Roman, Arlington’s Public Information Officer, Civic Academy takes place over the course of six weeks and aims to provide participants with the information they need for constructive civic engagement. Applications are open from now until August 4th for the fall session, which will take place between September 12th and October 17th.
Find Out How the Town Works
It’s clear that town government takes the Academy seriously. The Town Manager, Select Board Chair, Town Moderator, and the heads of several town departments have stayed late into the evening to attend Civic Academy sessions. Their formal presentations do a great job of explaining how different areas of town government work and how best to get involved, but the chance to meet them and ask them questions is equally valuable. The participants usually have a lot of very insightful questions, and it’s a great opportunity to learn more and become a more effective advocate in the future.
Participants Make Arlington Civic Academy Great
The other participants are another great part of the program. It’s also a great chance to make connections with other people who are equally enthusiastic about learning and getting involved in making their town a better place. There have been two sessions of the program so far, and several participants have gone on to run for Town Meeting, join the Master Plan Update Advisory Committee, volunteer for last fall’s tax override campaign, and propose warrant articles. We just had a get-together for members of both Civic Academy sessions to meet each other and network, and are hopeful that Civic Academy alumni can help connect future participants in the program to opportunities to get involved in helping Arlington become even better.
Helping Others Learn to Navigate Town Processes
I ran for Town Meeting this spring after attending Civic Academy last fall, and I found that it served me well after I was elected. It taught me how the budgeting process worked, including all the steps from the Town Manager’s office working with individual departments, the Finance Committee compiling a cohesive budget, and Town Meeting approving that budget. When constituents from my precinct have questions about how to get help with something from the town, I know which boards or committees or town departments they should reach out to. I also have a better understanding of the current constraints and opportunities faced by our town across multiple areas.
When I started working with Paul Schlictman on advocating for extending the Red Line further into Arlington, I reached out to the members of my Civic Academy class to see if they were also interested, and several of them were incredibly generous with their time and helped us set up our website and mailing list. I would highly recommend applying to Civic Academy, and I’m very thankful that the town puts so much effort into making it a great experience.
