Mass ADU
Mass ADU helps Massachusetts homeowners understand, plan, and navigate Accessory Dwelling Units (ADUs).
We specialize in educating homeowners on Massachusetts ADU zoning, design options, permitting pathways, and real-world considerations so they can make informed decisions before starting a project. Our workshops are designed to be clear, practical, and grounded in current Massachusetts regulations.
Mass ADU hosts free educational ADU workshops for homeowners across Massachusetts, covering topics such as local zoning rules, typical costs, design approaches, and common pitfalls to avoid. Our goal is to help homeowners understand whether an ADU is feasible for their property — without pressure or sales tactics.
