WHAT IS AN ADU? 

An Accessory Dwelling Unit (ADU) is a smaller, self-contained living space on the same property as your main home — with its own entrance, kitchen, bathroom, and sleeping area. ADUs can be created in several ways: by converting part of your existing house like a basement or attic, adding on to the main home, or building a separate detached unit in your yard.

WHAT DOES MASSACHUSETTS NEW LAW MEAN? 

The Commonwealth of Massachusetts recently passed a law that makes ADUs easier to build statewide. As of February 2, 2025, cities and towns must allow at least one ADU by right in single-family residential districts, meaning homeowners no longer need a special permit or zoning variance for a compliant ADU project. This change is intended to expand housing options, help address the state’s housing shortage, and give homeowners more flexibility in how they use their property.

WHO CAN BENEFIT FROM ADU CONSTRUCTION?

Massachusetts homeowners are turning to ADUs to support aging parents, generate rental income, and create long-term flexibility — but zoning rules, permits, and design decisions can feel overwhelming.

 

Patriot ADU helps you navigate the process clearly, legally, and confidently.
