Frequently Asked Questions About Attached ADUs

01.
Can I convert a garage or basement with an attached ADU?
Yes. Many homeowners convert basements, garages, and other underutilized areas in their homes with an attached ADU to create a more functional space.
02.
Does an attached ADU require a separate entrance?
In Massachusetts, an ADU is explicitly required by the new ADU law to have a separate entrance. Some communities require the separate entrance to face certain directions.

Can I rent out an attached ADU?
