One of the attractions of tiny houses is the ability to place the small structures on a trailer with wheels, creating a mobile — or portable — dwelling. This allows the occupants the option of moving whenever the mood strikes them. But this modern day nomadic lifestyle hit a roadblock in Maine this past summer when municipalities were notified by the Maine Secretary of State that the Bureau of Motor Vehicles would no longer register, assign vehicle identification numbers to or title tiny homes on wheels. The registration and title rules change in Maine does not impact tiny homes that are built or placed on permanent footings or foundations. [A Maine couple built their own tiny house, then the town declared it illegal] In early 2018, Maine tiny living got a boost when the state’s building codes were amended to include guidelines for the dwellings.
