Tiny House Regulations Maine

  • Tiny house regulations and codes may vary by city, town, or county.
  • Maine has created statewide construction guidelines for tiny houses; defining them as a dwelling less than 400 square feet allowing sleeping lofts, permitting ladder access to lofts, and approving skylights as points of emergency egress.
  • It’s important to note that towns are still able to approve or deny the construction of tiny houses.
  • In most cases, your tiny house built on a permanent foundation needs to comply with Maine Uniform Building and Energy Code.
  • Camping in a tiny house on wheels is allowed in North Yarmouth, Maine as long as:
    • When placed on a site for more than 120 days per year, all requirements for residential structures are met.
    • You do not build on a permanent foundation.
    • It is on the lot existing before the date of the ordinance or larger than 30,000 square feet.

Maine is one of the few states that have approved tiny house construction requirements. The requirements begin with a definition of a tiny house as any home that is smaller than 400 square feet. Sleeping lofts with access via ladders are permitted. Skylights in loft areas are permitted as an emergency exit area. Tiny homes with a permanent foundation must conform to the requirements established under the Maine Uniform Building and Energy Code in most instances. While these construction guidelines pertain to all tiny homes in the state, cities are able to deny construction requests. In some areas, boat houses are being converted into an accessory dwelling unit under construction guidelines for tiny homes.

March 2020:  Maine Secretary of States Office will classify Tiny Houses on Wheels and issue a Title per Maine Statute. This means once a Title is issued the THOW does not fall under jurisdiction of local building Codes. Zoning codes would still apply. The Full Statute can be found in this link. Each individual town can specify where in the town a tiny home can be parked in their zoning or land use ordinance. Only 1 town in Maine has done this – Chelsea, Maine. All other towns are allowing or not allowing tiny homes based on their interpretation of their existing zoning ordinances.
