  • Tiny house regulations and codes may vary by city, town, or county.
  • ADUs (accessory dwelling units) are allowed in many towns and cities in Massachusetts. See the full list here.
  • Specifications of an ADU are specific to each city or town.
  • Nantucket allows a third dwelling of up to 550 square feet.
  • Tiny houses on wheels are more difficult because the state hasn’t clearly addressed or defined what they are.
