ADU Design in Maine: what governs your project
Maine's 2022 housing law (LD 2003) requires municipalities to allow ADUs, limiting local restrictions on where accessory units can be built. It is one of the stronger state-level ADU frameworks in New England.
Energy code
Local permitting still governs building code, setbacks, and shoreland zoning near water bodies. Septic-system review is a key constraint in rural areas; fees vary by municipality.
Permitting & plan check
Organized municipalities issue their own permits under MUBEC, while the Land Use Planning Commission (LUPC) handles planning, zoning, and building permits across Maine's unorganized territories — a uniquely large jurisdiction. DEP and shoreland reviews overlay local permitting near water resources.
Good to know
- Maine's Land Use Planning Commission (LUPC) directly governs planning and zoning for millions of acres of unorganized territory.
- The Maine Uniform Building and Energy Code (MUBEC) applies even in towns with no local building department.
- Presumpscot clay, a glaciomarine deposit along the Maine coast, is one of New England's most challenging foundation soils.
