Off-Grid Living in Cooper, Maine

I've been digging into small unorganized-feeling towns in Washington County, Maine, and Cooper is a good example of how little land-use regulation can exist once you're outside the shoreland zone. Here's what I found, and where the gaps are.

Zoning. Cooper does not have a town-wide general zoning ordinance, based on what I could find. The only confirmed local land-use rule is its Shoreland Zoning Ordinance, which the town adopted because Maine requires every municipality to regulate land within roughly 250 feet of water bodies and wetlands and 75 feet of streams. Outside that shoreland band, Cooper appears to be unzoned, meaning raw land use on interior parcels isn't governed by a town zoning ordinance at all. That doesn't mean anything goes, though. State rules on wastewater and plumbing still apply everywhere.

Dwellings, tiny homes, RVs. Inside the shoreland zone, the ordinance limits campsite density (one per lot or per 30,000 square feet) and restricts clearing in Resource Protection Districts. Important detail: if you park an RV, tent, or similar shelter on a lot for more than 120 days a year, the ordinance treats it like a residential structure, which means it needs a compliant subsurface sewage disposal system under state rules. I found nothing confirming rules for RVs or tiny homes outside the shoreland zone, so that's a call to the town office.

Building permits. Maine requires every municipality to appoint a code enforcement officer, but the statewide building code (MUBEC) is only mandatory for towns over 4,000 people. Cooper's population is around 168, well under that threshold, so whether Cooper has locally adopted MUBEC isn't confirmed in my research. Ask the town office directly before you build.

Septic and greywater. Septic is handled through Maine's Subsurface Wastewater Disposal Rules, administered locally by Cooper's Local Plumbing Inspector, who must approve a written sewage disposal plan for shoreland campsites. Greywater isn't addressed separately in anything I found; it falls under the same state subsurface rules.

Rainwater and wells. No Cooper ordinance on rainwater harvesting turned up in my research. Wells fall under the state's Water Well Commission rules, and I found no town-specific well ordinance beyond general shoreland setbacks.

Utility disconnection. Nothing in Cooper's records directly addresses living off-grid or disconnected from utilities. Whatever obligations exist would flow through the shoreland, septic, and plumbing rules above.

Bottom line: Cooper leans permissive by omission rather than by explicit off-grid-friendly policy. Confirm anything not nailed down here with the town office before you commit to a parcel.
