Local zoning: organized municipalities (most of southern/coastal ME) require local permits in addition to state permits — dual track; a moratorium can be imposed even after state permits issued (unique ME vested rights doctrine). Land Use Planning Commission (LUPC): governs ~10.5 million acres of Unorganized Territory (UT) in northern/remote ME (much of Aroostook, Piscataquis, Somerset, Penobscot, Washington, Franklin, Oxford, Hancock counties). DACF Permit: required for solar ≥5 acres on High-Value Agricultural Land (HVAL) — new, eff. April 20, 2025.
