Off-Grid Living in Penobscot, Maine

I've been digging into what off-grid living actually looks like in Penobscot, Maine, a small coastal town in Hancock County, and here's my honest read on it.

First, a myth-buster: Penobscot is not "unzoned" in the way some rural towns are. The state of Maine requires every municipality with shoreline to adopt a Shoreland Zoning Ordinance, and Penobscot has one, most recently updated in 2022. That ordinance governs land within 250 feet of ponds, lakes, and wetlands, and 75 feet of streams, with standards laid out in a table tied to an official shoreland zoning map. Outside that shoreland band, the town relies on its own Land Use Ordinance rather than a traditional multi-district zoning map. Both are administered by the town's Code Enforcement Officer, currently Bryce Farnham, who also handles building inspections and compliance. So where you plan to put your off-grid setup, near water or not, really changes which rules apply.

On dwellings, I couldn't find town-specific language addressing tiny homes or RVs as year-round residences. That doesn't mean it's forbidden, it means it likely gets sorted out case-by-case when you apply for a permit through the Land Use Ordinance process, so I'd call the CEO before you commit to a structure type.

Building permits are required locally. Penobscot's population is small enough that it falls under the state's threshold where the Maine Uniform Building and Energy Code (MUBEC) is optional rather than mandatory, but the town still runs its own permit application through the Planning Board's office, and the CEO does inspections.

Septic and greywater both route through the same person locally: Bryce Farnham wears two hats as both Code Enforcement Officer and Plumbing Inspector. Septic systems and composting toilets are handled under Maine's statewide Subsurface Wastewater Disposal Rules (the underlying rules come from Maine CDC), but Farnham issues the local plumbing and septic permits, and greywater applications appear to go through that same plumbing permit process, since I found no town-specific greywater restriction.

Rainwater harvesting: I found nothing in Penobscot's ordinances addressing it either way, so I'm calling that unconfirmed rather than guessing.

Private wells aren't separately regulated by the town beyond the shoreland setbacks; well construction itself falls under state standards, and I didn't find a town well ordinance.

Living fully off the utility grid isn't explicitly banned anywhere I could find, but it isn't explicitly blessed either. In practice it flows through whatever building and septic permits you need anyway, enforced by the CEO.

Bottom line: Penobscot leaves a fair amount of room for off-grid living, but "no zoning" is not accurate, and the smart move is calling the Code Enforcement Officer before you buy land or build.
