Off-Grid Living in St. John, Maine

St. John Plantation is about as far off the beaten path as Maine gets, both geographically and regulation-wise, and my honest read after digging through the available sources is: nobody has published a zoning or land-use ordinance for this town online. That doesn't necessarily mean there isn't one, but I could not find it, and the University of Maine Law School's own ordinance guide for Aroostook County towns doesn't list one for St. John either, instead telling researchers to contact the town clerk directly. So my strong suggestion, before you buy land or move a camper onto a lot here, is to call the town office and just ask: is there a zoning ordinance, a building permit requirement, a minimum dwelling size?

One thing worth clearing up: Aroostook County government itself does not do zoning for organized towns like St. John Plantation. That authority (if it exists at all here) sits with the town. The state's Land Use Planning Commission only has jurisdiction over unorganized territory, and St. John is an organized plantation, so LUPC rules don't apply to you here.

On building codes: Maine only forces its statewide MUBEC code on towns above a population threshold, and St. John Plantation, with roughly 263 residents, is nowhere near that. That means any building permit or code requirement here would be a purely local, optional choice by the town, again, something only the town office can confirm.

Where I do have solid ground is septic and wastewater. That's a state-run program: the Maine CDC's Subsurface Wastewater Unit sets the rules statewide (covering standard systems, greywater disposal fields, and site evaluation standards), but the actual permit gets issued locally by the town's appointed Local Plumbing Inspector (LPI). St. John Plantation should have one, but you'll need to ask the town clerk who currently holds that role, since I could not find a name attached to this office online.

Wells follow the same pattern: state standards for construction apply everywhere in Maine, and Maine DEP points people with groundwater or well questions to their local code enforcement officer or LPI as a first stop.

Rainwater harvesting and general "living off utilities" don't appear to be addressed by name in any Maine statute or in anything I could find specific to St. John, so I'd call that unclear rather than assume it's fine or restricted.

Bottom line: this looks like a town where the state rules (septic, wells) are clear and the local rules (zoning, building, dwellings) are a blank page that only the town clerk can fill in for you. Don't skip that call.
