County Building Permits
Knox County, ME - 2026 Building Permit Guide
How to apply for a building permit in unincorporated Knox County, Maine. Permit authority, application steps, fees, and inspection requirements.
Permit Authority
Knox County has very little unincorporated territory -- virtually all land is within an incorporated municipality or organized plantation. For the rare unincorporated parcel, Maine DEP, DHHS, and the Maine Land Use Planning Commission (LUPC) -- which primarily governs unorganized territory in northern Maine -- would have jurisdiction. Knox County is too far south and developed for significant LUPC coverage. Contact Knox County government and Maine DEP for any unincorporated parcel questions.
