Off-Grid Living in South Thomaston, Maine

I've been digging into South Thomaston, Maine for folks dreaming about a quieter, more self-reliant setup on the midcoast, and here's what I found. Short version: this is a zoned town, so "off-grid" here means working within local rules, not escaping them.

Zoning. South Thomaston has its own Land Use Ordinance plus a Shoreland Zoning Ordinance, both enforced by the town's Code Enforcement Officer (CEO). If your land is anywhere near a pond, stream, or the shore, expect to fall under one of several shoreland districts (Resource Protection, Limited Residential, General Development, and so on), each with its own rules about what you can build and how close to the water you can build it. Away from the shoreland zone, the general Land Use Ordinance still governs. Don't assume "rural" means unregulated, it's the CEO's job to enforce this town-wide.

Dwellings, tiny homes, RVs. The shoreland ordinance allows a limited number of recreational vehicles or tent campsites per lot in the shoreland zone, but this reads as a temporary/recreational allowance, not a legal pathway to living full-time in an RV or tiny home. I couldn't confirm any town-specific standard for permanent tiny-home dwellings, so if that's your plan, call the CEO before you buy land or a trailer.

Building permits. The town requires a Land Use Permit, issued through the CEO, and the CEO coordinates with the town's Local Plumbing Inspector (LPI) on septic-related work. I could not confirm whether South Thomaston has locally adopted Maine's statewide building and energy code (MUBEC), so ask the CEO directly.

Septic and composting toilets. This is one area with real teeth. The shoreland ordinance leans on Maine's statewide Subsurface Wastewater Disposal Rules, which set a minimum 100-foot setback from the normal high-water line for new systems near perennial water bodies, a setback that cannot be reduced by variance. Lots served by a subsurface system generally need to be at least 20,000 square feet, per state minimum lot size rules. The LPI issues these permits locally.

Greywater and rainwater. I found no South Thomaston-specific rule on either. Greywater disposal would fall under the same state Subsurface Wastewater Disposal Rules administered by the LPI. Rainwater harvesting appears to be simply unaddressed in local materials, neither blessed nor banned, so I'd treat it as a "confirm with the CEO" item.

Wells. No town-specific well ordinance turned up. Wells would follow Maine's statewide well siting and construction standards, independent of the town's zoning, though shoreland setback rules could still apply if your well sits near a water body.

Utility disconnection. I found nothing in South Thomaston's ordinances that explicitly bans living off-grid or disconnected from utilities. Any practical requirements come indirectly, through the building/land-use permit and septic permitting process described above.

Bottom line: the framework here is entirely workable for an off-grid-style property, but the shoreland setbacks and the CEO's permit process are real, and the fuzzy spots (tiny homes, rainwater) are worth a phone call before you commit.
