An ADU is a separate, smaller living unit with its own kitchen and bathroom facilities and separate entrance that is included within a larger resident (type 1), attached to a residence (type 2) or located in an accessory (“detached”) structure on the same lot as a main residence (type 3). For a variety of reasons, primarily cost and feasibility, the type 1 ADUs are by far the most common.
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.
This is our national challenge for the next 25 years, according to Jeffrey C. Fuhrer, Executive Vice President/Chief Strategy Officer for MassDevelopment, the Commonwealth’s economic development and finance authority.


Accessory Dwelling Units (aka “granny flats”)
Arlington has an opportunity to set up an Affordable Housing Trust Fund to provide more housing stability for its low and moderate income residents. The vote will occur in the Town Meeting starting Nov. 16, 2020.
A Guide for Arlington
The Massachusetts Housing Partnership put together this 2018 guidebook, v.3, to help municipalities adopt Municipal Affordable Housing Trust Fund (MAHT) legislation to suit the specific needs of each municipality.
For Arlington’s Nov 2020 Special Town Meeting, my colleague Ben Rudick filed the following warrant article:
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.
In the 1930’s the Home Owner’s Loan Corporation of America (HOLC) created actuarial maps of the United states. These maps were color coded — Green, Blue, Yellow, and Red — to reflect the amount of “risk” associated with home loans in those areas. The colors corresponded to “Best” (green), “Still Desirable” (blue), “Definitely Declining” (yellow), and “Hazardous” (red). Being in a green area made you likely to secure a federally-insured home mortgage, something that was effectively unavailable to red areas. Red areas were often associated with black populations, and these maps are where the term “redlining” comes from.
