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.

(This post was originally an email message, discussion open space changes proposed by an Affordable Housing article during the Arlington, MA’s 2019 town meeting. It’s also a decent description of our town’s open space laws.)
Sorry this turned out to be a long post. Our open space laws are kind of complicated.
Arlington regulates open space as a percentage of gross floor area, rather than as a percentage of lot area. Let me give a concrete example: say we have a-one story structure with no basement. It covers a certain percentage of the lot area, and has an open space requirement based on the gross floor area (i.e., the interior square footage of the building).
Now, suppose we want to turn this into a two- or three-story structure. The building footprint does not change, and it covers exactly the same percentage of the lot area. However, the open space requirements double (if you’re doing a two-story building), or triple (if you’re doing a three story building). If that quantity of open space isn’t on the lot, then you can’t add the stories.
For this reason, I’d argue that our open space regulations are primarily oriented to limiting the size of buildings. You really can’t allow more density (or taller buildings) without reducing the open space requirements. Alternatively, if the requirements were based on a percentage of lot area, we probably wouldn’t need a reduction. (Cambridge’s equivalent is “Private Open Space”, and they regulate it as a percentage of lot area.)
The other weird thing about our open space laws is that we define “usable open space” in such a way that it’s possible to have none. (Usable open space must have a minimum horizontal dimension of 25′, a grade of 8% or less, and be free of parking and vehicular traffic). I live on a nonconforming lot that does not meet these requirements, as do the majority of homes in my neighborhood.
Suppose I wanted to build an addition, which would increase the gross floor area. With the non-conformity, I’d have to go in front of the ZBA and show that the current lot has 0% usable open space, and that the house + addition produces a lot with 0% usable open space. Because 0% = 0%, I have not increased the nonconformity, and would be able to build the addition, provided that all of the other dimensional constraints of the bylaw are satisified. Although this isn’t directly related to Article 16, it’s an amusing side effect of how the bylaw is written.
Finally, roofs and balconies. Section 5.3.19 of our current ZBL allows usable open space on balconies at least six feet wide, and on roofs that are no more than 10′ above the lowest occupied floor. We allow 50% of usable open space requirements to be satisfied in this manner.
The relevant section of Article 16 would create a 8.2.4(C)(1) which includes the language
Up to 25% of the landscaped open space may include balconies at least 5 feet by 8 feet in size only accessible through a dwelling unit and developed for the use of the occupant of such dwelling unit.
Article 16’s incentive bonuses strike the usable open space requirement, and double the landscaped open space requirement. With only landscaped open space, 5.3.19 doesn’t apply (it only pertains to usable open space). The language I’ve quoted adds something 5.3.19-like, but for landscaped open space. I say 5.3.19-like because it has a 25% cap rather than a 50% cap, and requires eligible balconies to be at least 5’x8′, rather than 6′ wide.
Here are a few pieces of supporting documentation:
- definitions of landscaped and usable open space from our ZBL
- a diagram to illustrate the difference between landscaped and usable open space.
- The text of section 5.3.19 (which is referenced by the diagram)

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.

Massachusetts is experiencing a housing affordability crisis and a climate crisis. For these reasons, Mothers Out Front Arlington supports changes in zoning by-laws that allow greater density in housing near public transit. Mothers Out Front is supportive of the passage of a meaningful MBTA Communities Act that encourages the development of more multi-family housing and a greater diversity of home types in Arlington. A revised zoning by-law to allow for more multi-family housing will reduce pressure to build single family homes on undeveloped land elsewhere in Massachusetts. This safeguards undisturbed ecosystems and provides real alternatives to automotive commutes in the region, reducing both congestion and fossil fuel emissions. In addition, passing this by-law will allow Arlington to participate in the Massachusetts pilot for communities to build fossil fuel-free homes, thus ensuring that new construction in Arlington supports our net-zero climate goals.
Mothers Out Front Arlington respects the public engagement activities that inform the Working Group’s MBTA Communities Act proposal. We appreciate that the Working Group is working with the Town to identify opportunities for developer incentives to encourage public open spaces, mitigate heat islands, and increase the tree canopy. Similarly, the Town’s commitment to maintaining current (and incentivizing higher) zoning requirements for affordable housing also is important to our group. For these reasons, Mothers Out Front Arlington strongly urges the Arlington Redevelopment Board to accept the MBTA Communities Act plan as proposed by the Working Group.

In 2023, Lexington was one of the first towns to comply with the State “MBTA Communities” law (MBTA-C) by adding 227 acres to several multifamily overlay zones. When discussing this proposal, it was estimated to possibly generate 400-800 units in 4-10 years. However, after receiving building permit applications for about 1,100 units in the first year (including 160 inclusionary affordable units), Lexington passed Article 2 at a Special Town Meeting recently, which decreased the amount of land in these zones to approximately 90 acres. What can Arlington learn from Lexington’s experience?
Overall, Lexington’s experience shows us that developers are willing and able to build multifamily housing on large lots that aren’t very built up, and that MBTA-C can be successful in adding new housing in some circumstances. However, Arlington has few if any large, sparsely-built parcels zoned to allow multifamily housing under MBTA-C. As such, Arlington is unlikely to add significant amounts of new housing or affordable housing as a result of the MBTA-C overlay passed at Town Meeting in fall of 2023.
Parcel Size and Existing Buildings
Many of the parcels in Lexington’s MBTA-C zone are multiple acres each, are underutilized, and contain older office space. In contrast, Arlington’s MBTA-C parcels are much smaller and mostly covered with existing buildings, typically residential.
The largest development approved under MBTA-C so far in Lexington is at 3-5 Militia Drive. This land is three very large parcels containing a couple older office buildings, a previous religious institution, and giant surface parking lots. Therefore, such a property was already primed for redevelopment and the large lots allowed for 292 units to be approved. These parcels are also within walking distance of Lexington Town Center and the Minuteman Bike path, so multi-family housing on this location is a great use.
In contrast, there are no similar parcels in Arlington in the MBTA-C zone with large surface parking lots and aged office space that could be redeveloped in such a manner. One of the few parcels in Arlington that is somewhat similar to the planned parcels for redevelopment in Lexington would be the Walgreens at 324 Massachusetts Ave, 1.5 acres with a surface parking lot. However, this parcel was specifically excluded from the MBTA-C overlay along with all other business parcels to avoid displacing any existing business space. And the parcel is unlikely to be redeveloped one way or another unless Walgreens chooses to close their business and sell the parcel to a developer.
In short, compared to Lexington, Arlington is “built out” insofar as almost every parcel is utilized in some manner with high lot coverage. The original Lexington MBTA-C zone contained many parcels with low lot coverage, large surface parking lots, and underutilized office space, all attributes that make such parcels more likely to be sold to a developer to construct housing if permitted by zoning.
Last, while 1,100 units have been permitted so far, this does not mean all these units will be constructed given current financial uncertainty in the economy and high interest rates. It will also take several years for these properties to be completed and prepared for occupancy. As such, the original estimate of 400-800 units in 4-10 years (an estimate that actually widely ranges from 40 units all the way to 200 units per year) may in fact not be that far off from the final numbers once buildings are completed. The parcels most primed for redevelopment were acquired and permitted first. Finally, it is not entirely clear how many more parcels would have been redeveloped in the next 5-10 years had the Lexington MBTA-C zoning not been reduced in size.
Development Potential in Arlington
Most privately owned lots in Arlington are less than ⅓ of an acre with many much smaller, significantly limiting the amount of new housing development on any single parcel. Almost all of these lots are covered by existing buildings, and some of those buildings are condominiums. Therefore, in order for a large new construction project to occur on such parcels in Arlington’s MBTA-C multifamily zone, all of the following would have to take place:
- a single owner would have to take control of multiple lots and/or condominiums, meaning that
- multiple existing property owners would have to want to sell at the same time, or else the new owner would have to take the time and risk to assemble the property slowly, and
- the new proposed development would have to be large and profitable enough to make up for the combined purchase prices of all the properties acquired.
Meanwhile, properties in Arlington generally turn over at a fairly slow and steady pace. This is in contrast to underused large commercial properties, whose owners are more eager to sell.
With simulation modeling performed on potential rate of redevelopment, the Arlington Redevelopment Board’s 2023 Report to Town Meeting on the MBTA-C proposal projected that 15–45 parcels could be redeveloped over the next ten years, for a net increase of 50–200 new units or 5–20 per year, far fewer than even the initial Lexington housing unit construction estimates at the time of passage of their initial MBTA-C zoning.
In fact, Arlington has seen even less than the low end estimate of 5 units per year so far since our MBTA-C zoning became effective. Only a single project has been permitted so far, which would turn an existing 2-unit building into 4 units, a potential net gain of 2 housing units.
Lessons
- There is strong regional demand for housing including for multifamily units.
- Developers are currently willing and able to build when lots are available, are zoned multifamily, and aren’t already full of other buildings.
- Arlington can’t expect anywhere near as many new units with our current zoning as Lexington saw, because our MBTA-C multifamily zones are almost exclusively made up of smaller and built-up lots.
- As a result, Arlington’s current zoning won’t add much housing or affordable housing to our community, and won’t noticeably increase our tax base either.

The Housing Corporation of Arlington (HCA), the Town’s non-profit housing developer, is excited to create a new development on Sunnyside Ave with 43 new affordable homes. The homes will be a diverse mix of sizes and serve people of different incomes, all under 60% of the area median income. Arlington and the entire Greater Boston region have a severe shortage of affordable housing, which this project will help to address. Arlington’s Master Plan, Housing Plan, and Housing Trust Action Plan all acknowledge the need to create significantly more affordable housing.
The HCA’s new Sunnyside Ave proposal is located just off Broadway, near the Alewife Brook DCR Greenway and the Somerville line; it’s a great location near a supermarket, bus lines, and a modest walk to Davis Square. Currently, the site is a dilapidated former auto body shop. The proposal is designed to meet the specific needs of HCA’s residents and the Arlington community. The development will be Passive House certified. It includes 21 vehicle parking spaces, approximately 70 bike parking spaces, and a 2nd floor roof garden for tenants to enjoy. The development also includes a community room that the HCA will share with other local groups. The project will also add a sidewalk on Sunnyside Ave where there currently isn’t one. HCA owns the site and expects to start seeking zoning approval in the spring.
Building affordable housing is a long and complicated process, due to the permitting process plus the number and complexity of funding sources needed. The state’s Department of Housing and Community Development receives many more requests than they can fund in every funding round. We expect to complete the permitting process in 2023, secure our financing by the end of 2024, and start construction in early 2025. With an expected construction timeline of around one year, HCA expects to see tenants moving into the building in spring, 2026. A public forum on the project is anticipated in the coming months. Given the complicated funding and permitting challenges, your monetary and public support of our new development on Sunnyside Ave would be appreciated.
The Housing Corporation of Arlington is a non-profit, community-based developer and owner of affordable housing in Arlington. It owns 150 units of affordable rental housing in all parts of town. The units are occupied by a diverse mix of families and individuals. HCA has been purchasing, rehabilitating, and building new housing since 2000, and also provides social service programs to support family stability and build community connection and engagement. Every week, HCA staff help local families who are struggling with the extreme cost of housing, making the creation of more affordable homes both urgent and important.
The staff, board of directors, and the more than 1,000 tenants, donors, and members who make up the HCA organization are very excited about this opportunity to expand Arlington’s portfolio of affordable housing. Our most recent projects included three newly constructed buildings—two in Downing Square (Lowell Street) and a mixed-use property shared with “Arlington Eats” on Broadway.

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:

The upcoming articles in this series will focus on each individual element in the Town of Arlington’s Master Plan.
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 Tuesday August 6, 2024, Governor Healey signed the Affordable Homes Act (H.4977) into law. It’s a significant piece of legislation that will take positive strides toward addressing our state’s housing crisis. At 181 pages, the Affordable Homes Act is a lengthy bill, but the things it does generally fall into three categories: funding, changes to state law, and changes to state agencies.
The act authorizes more than five billion dollars to fund the creation, maintenance, and preservation of housing. This includes $425M to housing authorities and local housing initiatives (including $2.5M for the Arlington Housing Authority), $60M to assist homeowners or tenants with a household member with blindness or severe disabilities, $70M for community-based efforts to develop supportive housing for persons with disabilities, and $100M to expand opportunities for first-time homebuyers.
The Affordable Homes Act makes several changes to Massachusetts zoning laws, including the legalization of accessory dwelling units (ADUs) statewide. ADUs, also known as “granny flats” or “in-law apartments,” are a cost-effective way to add new housing, and they’re typically used to provide living quarters for relatives or caretakers, or to generate rental income for homeowners. ADUs are now allowed in all single-family zones in Massachusetts, by right, without the need for a discretionary permit. Arlington has been a leader in this area, having passed an ADU bylaw in 2021, and it’s great to see this option extended throughout the Commonwealth.
Finally, the Affordable Homes Act makes a number of changes to state agencies, especially the Executive Office of Housing and Livable Communities (EOHLC). The Act establishes a new Office of Fair Housing within the EOHLC, to “advance the elimination of housing discrimination.” The Fair Housing office will provide periodic reports on progress towards achieving this goal. EOHLC is also charged with creating and implementing a state-wide housing plan that will consider supply and demand, affordability, challenges unique to different regions of the state, and an analysis of local zoning laws.
While our legislators deserve kudos for putting this package together, they also deserve kudos for what they left out. More than three hundred amendments were filed during House deliberations, and a number of them were intended to weaken the multi-family housing requirements of the MBTA Communities Act. For example, one amendment, simply titled “Technical Correction” would have rewritten the transit community definitions, in order to reduce the housing requirements for Milton. We are heartened that our legislators did not go along with such shenanigans.
