City of Portland (ME) Zoning Administration ↗Septic is governed statewide by the Maine Subsurface Wastewater Disposal Rules (Maine CDC); permits are prepared by licensed site evaluators and issued/inspected locally by the municipal Licensed Plumbing Inspector.
Maine CDC - Subsurface Wastewater System Permitting ↗Maine has no statewide residential contractor license; a homeowner may apply for permits and build their own home, subject to municipal code enforcement.
