Accessory Dwelling Units in Massachusetts

Accessory Dwelling Units (ADUs) are becoming an increasingly popular choice for Massachusetts homeowners looking to add flexible living space and value to their property. Also known as in-law apartments, guest houses, or backyard cottages, ADUs provide an independent living space for aging parents, adult children, guests, or extended family.

Recent changes to Massachusetts ADU laws have made it easier for many homeowners to add an accessory dwelling unit to their property. ADUs may be created as an addition, within an existing home, through a garage or basement conversion, or as a detached backyard residence.

At Barlow Design & Construction, we specialize in ADU design and construction in Massachusetts, guiding homeowners from initial planning and design through permitting and construction. Whether you're planning an in-law suite, detached ADU, or guest cottage, we create thoughtfully designed spaces that complement your home and meet your family's needs—today and for years to come.
