The state is launching a new campaign to better educate Mainers about accessory dwelling units, or ADUs.
A Maine law, passed more than two years ago, requires municipalities to allow at least one ADU on any lot with a single-family home.
Despite the law, ADUs are generally not the norm throughout the state, said Kristina Egan, executive director of the Greater Portland Council of Governments, which is spearheading the campaign in partnership with the Maine Department of Economic and Community Development.
“While they’ve been around for a long time, they haven’t been actively promoted by the state or seen as a big part of the housing solution until recently,” Egan said. “Our hope is that more accessory dwelling units will be built.”
