What Our Customers Say
FAQs
Are ADUs legal in Boston?
Yes! Most single-family homeowners can build an ADU on their property, but it may depend on zoning regulations, lot size, and design constraints.
Boston has updated ADU pilot programs in certain neighborhoods, and rules vary by area. We handle all permitting to ensure your unit complies with local requirements.
What types of ADUs can I build in Boston?
Boston allows attached, detached, and basement/garage conversion ADUs in certain zoning districts. We can help determine the best option for your property.
How much value does an ADU add to a home in Boston?
An ADU can significantly boost property value by creating additional living space and rental potential. Beyond resale, many homeowners find the true value is in long-term flexibility — whether it’s housing family members, lowering retirement expenses, or generating steady rental income in a high-demand city.
How long does ADU construction take in Boston?
Timelines depend on scope. A simple basement conversion might take a few months, while building a detached unit with utilities and full foundations can extend to a year or more. The permitting process in Boston also adds time, so working with our experienced contractors can streamline the schedule.
