Off-Grid Living in Cornish, Maine

Cornish, Maine is a small town in York County, and I want to be upfront about something a lot of people assume wrong: Cornish is NOT an unzoned rural town where you can just go build whatever you want on raw land. It operates under a full Land Use and Development Ordinance, administered by a Code Enforcement Officer (CEO), a Planning Board, and a Board of Appeals, with a Shoreland Zoning overlay layered on top per state law. That ordinance traces its authority back to Maine's Home Rule statute and the state Subdivision Law and Shoreland Zoning statute, but the specific district map, table of permitted uses, and dimensional standards are all set locally by Cornish.

Zoning and land use. Cornish has an official Land Use District Map and a Table of Permissible Uses that spells out, district by district, what you can do and whether a permit is required. Before buying or building on any parcel, I'd pull that map and table and confirm your specific lot's district with the CEO.

Dwellings, tiny homes, and RVs. I could not find a specific Cornish provision addressing tiny houses or RVs as permanent dwellings. The ordinance does set dimensional and setback standards for dwellings generally, but whether an RV or tiny home qualifies is a question only the CEO, Dan Vaillancourt, can answer for your situation.

Building permits. Cornish requires a building/use permit from the CEO for uses allowed under the ordinance. Maine's statewide building code (MUBEC) rules apply too, and the state's Office of State Fire Marshal handles code enforcement questions that go beyond the local level.

Septic and composting toilets. Maine's Subsurface Wastewater Disposal Rules, administered statewide by Maine CDC, permit composting and alternative toilets. Locally, the same CEO also serves as Cornish's Plumbing Inspector, so he's your point of contact for septic and toilet permitting.

Greywater. Also governed by the statewide Maine CDC rules, requiring a licensed site evaluator and permit. Same local contact: the CEO/Plumbing Inspector.

Rainwater harvesting. I found no Cornish ordinance language addressing rainwater collection specifically, and no state prohibition either. This one is genuinely unclear at the local level, so ask the CEO directly if you're planning a rainwater system as your primary water source.

Wells. Cornish has its own organized Cornish Water District serving at least part of the village area, with its own trustees and operator. Outside that service area, private wells fall under Maine's statewide well drilling rules. Confirm with the Water District office for anything near their service territory.

Off-grid utility disconnection. No explicit Cornish rule bans living disconnected from the grid. Any requirements would come indirectly through the building/use permit process and state septic and well compliance, both enforced by the CEO.

Bottom line: Cornish is a real zoned town, not a blank slate, so the CEO's office is your first and most important call before buying land or starting a build.
