Frequently Asked Questions About ADU Construction Near Boston

What is an ADU?

An ADU (Accessory/Auxiliary Dwelling Unit) is a secondary living space on the same property as your primary home. This can be a backyard cottage, basement living space, in-law suite, or converted garage that has its own kitchen, bathroom, and private entrance.

Are ADUs legal in Massachusetts?

Yes! Many Massachusetts towns, including Newton, Lexington, and Brookline, allow ADUs under specific zoning rules. Regulations vary by town, so our team guides you through what’s possible on your property and secures the necessary permits before we begin.

How much does it cost to build an ADU in Greater Boston?

Costs depend on size, type (detached, attached, garage conversion, basement), and finish level. In general, ADUs in Greater Boston range from $250,000 to $600,000+. We provide a transparent estimate during our pre-construction phase, so you know exactly where your investment stands.

Is financing available for ADUs?

Yes. We offer access to flexible financing through Enhancify, with 60-second applications and over 30 competitive options including HELOCs and unsecured personal loans.

How long does it take to build an ADU?

From design through permitting and construction, most ADUs take 8–12 months. Detached ADUs may take longer due to site prep and utilities, while conversions can move more quickly.

Can I design my ADU to match my home?

Definitely. We specialize in custom design-build projects, so your ADU will complement your home’s style. We happily replicate modern, contemporary, or classic New England architecture.
