Off-Grid Living in Boothbay Harbor, Maine

I've been digging through Boothbay Harbor's Land Use Code and the state rules that sit underneath it, and here's the honest picture for anyone dreaming of an off-grid setup on the peninsula.

First, an important distinction: Boothbay Harbor is its own municipality, separate from the neighboring Town of Boothbay. Don't mix up the two ordinances, they're administered independently.

Zoning. Boothbay Harbor is fully zoned, this is not unzoned rural land. The town's Land Use Code (Chapter 170 on eCode360) is enforced by the Code Enforcement Officer under Planning Board oversight, and it splits the town into districts, General Residential, Special Residential, Downtown Business, and more. On top of that, a mandatory Shoreland Zoning overlay applies near water, which also involves the Maine DEP. If you're eyeing waterfront or near-shore land, expect extra review.

Dwellings, tiny homes, RVs. I could not find a specific town provision carving out tiny homes or RVs as a distinct dwelling category. That means any structure you put up likely falls under the general permitting and district use tables in the Land Use Code. Confirm your specific plan with the Code Enforcement Officer before you buy land or a trailer.

Building codes. Maine requires municipalities to enforce the Maine Uniform Building and Energy Code (MUBEC), per state law (10 M.R.S.A. § 9724), and Boothbay Harbor has applied it since December 2010. The Code Enforcement Officer is the town's building official and issues permits and certificates of occupancy.

Septic and composting toilets. Subsurface wastewater systems, including alternative and composting toilet setups (beyond simple pit privies), fall under Maine's statewide Subsurface Wastewater Disposal Rules. Locally, the Local Plumbing Inspector issues internal plumbing permits and reviews these systems. I didn't find a town-specific restriction beyond the state baseline.

Greywater. Same story, state rules (a licensed site evaluator plus an LPI-issued permit) govern greywater disposal fields. The town's code explicitly defers to state and federal law where it has no provision of its own.

Rainwater harvesting. No Boothbay Harbor ordinance turned up on this. Practically, general state plumbing code standards would likely apply, but this is genuinely unclear at the town level, so ask the Code Enforcement Office directly.

Wells. No town-specific well ordinance found. Maine's Water Well Commission rules on siting and construction would be the baseline.

Full off-grid living. There's no outright ban I could find, but don't read that as a green light to skip permits. MUBEC compliance and an LPI-approved wastewater system are required regardless of whether you're hooked to the grid. "Off-grid" doesn't mean "off the code books" here.

Bottom line: Boothbay Harbor is a real, actively zoned town with state-code enforcement layered on top. Nothing here screams "off-grid friendly," but nothing outright forbids it either, you'll just need to work through the same permitting process as any other builder in town.
