Join us at a March 14 seminar on accessory dwelling units

Developers do not build small homes in Acton. If we want smaller homes, this is one of the few ways to add such units.

Accessory dwelling units (ADUs) may be a confusing term, but it is a simple concept. With recent changes in state law and town zoning regulations, many Acton homeowners can now create a second, small dwelling unit on their property. It can be in the existing structure, over a garage, or in a small detached building.

We often think of ADUs as “mother-in-law apartments,” but they serve multiple purposes. An ADU can move a “boomerang kid” out of the basement and into a small home of his/her own. An aging homeowner can move into a small, modern dwelling and have the next generation live in (and keep up) their big house. A caregiver could live in the ADU. The new unit — or the existing home — can be rented out, and a new housing opportunity becomes available in Acton.

There are limits. The ADU cannot be larger than 1,000 square feet. It cannot be sold separately; it is part of the existing real estate parcel. It must comply with all health, safety, and building codes.

Developers do not build small homes in Acton. If we want smaller homes, this is one of the few ways to add such units. And they are not publicly financed. In effect, homeowners are benefiting themselves while adding to our accessible housing stock.

Acton homeowners are already building ADUs. To provide more knowledge, the Acton Housing Foundation and the League of Women Voters will hold an ADU workshop on Saturday, March 14, at 10:30 a.m. at the Acton Free Public Library. 

Join us and knowledgeable builders, bankers, and architects, as well as neighbors who have built or are building ADUs. Attend and learn how to help yourself while you help your town.
