Vermont’s law on equal treatment of housing and town bylaws requires municipalities to allow homeowners to add one Accessory Dwelling Unit (ADU) to their house as a permitted use as long as certain conditions are met.
NOTE: Legislation enacted in 2020 made substantial changes to the State's planning and development law including changes affecting how municipalities regulate ADU's. The Department has created the following checklist for homeowner's interested in developing an ADU and will be updating the full brochure.
