Mass ADU is a Massachusetts-based Accessory Dwelling Unit (ADU) construction company focused on helping homeowners build for the future. We provide statewide feasibility, permitting, and ADU construction services, guiding clients through the entire process from an initial consultation, through feasibility and permitting, all the way to construction – including custom builds and prefab/modular ADU options.
Our goal is to make ADUs approachable and practical, helping homeowners create long-term solutions that support their families, finances, and changing needs.
In addition to our construction services, we host local ADU workshops designed to help homeowners understand the process – from zoning and site feasibility to design and permitting. These sessions give people a chance to ask questions, get clarity, and understand what’s possible on their property.
If you’ve been considering an ADU or just want to learn more, we’re always happy to connect or have you join an upcoming workshop.
