How Is an ADU Defined Under Massachusetts Law?
Under Massachusetts law, an ADU is defined as a separate living space that includes essential facilities such as a kitchen, bathroom, and living area.

The implications of this definition are significant, as it establishes the framework for what constitutes an ADU and the requirements for construction.
What Are the Common ADU Types: Detached, Attached, and Conversions?
- Detached ADUs: Standalone structures separate from the main house, often resembling small cottages or guest houses.
- Attached ADUs: Integrated into the existing home, such as a converted garage or an extension of the main living space.

These options provide flexibility for homeowners to choose the best fit for their property and needs.

Accessory dwelling units and micro apartments are two typologies of small housing which have recently gained prominence. This paper finds that these two typologies have the potential to offer significant benefits to communities by providing affordable housing, decreasing the environmental impact of new construction and by providing options to diversify the homogeneous American housing stock. Several major barriers are identified which hinder the implementation of these small housing typologies, including neighborhood resistance, institutional uncertainty and hostile zoning and planning codes.

ADUs also provide valuable lifestyle benefits, particularly for families seeking multi-generational living solutions.
