Off-Grid Living in North Berwick, Maine

I've been digging into North Berwick, Maine, for anyone thinking about going off-grid here, and the honest answer is: it's a zoned town, so more of the rulebook applies than in an unorganized township, but there's real ambiguity once you get into the specifics of tiny homes and off-grid utilities.

Zoning. North Berwick has a formal Zoning Ordinance, last revised in 2023, administered by the town's Code Enforcement Officer (CEO). It includes Shoreland Zoning provisions and rules about non-conforming structures, notably that you can't change the use of a non-conforming structure unless the Planning Board decides the new use won't have a greater adverse impact. Beyond that, I don't have confirmed details on minimum lot sizes or setbacks outside the shoreland districts from what I've reviewed, so if you're eyeing raw land, pull the full zoning PDF or call the CEO before you assume anything.

Dwellings, tiny homes, RVs. This is genuinely unclear from what I found. The town follows the Maine Uniform Building and Energy Code (MUBEC), which is a state-level requirement under Maine law, but how that code and the local zoning ordinance treat a tiny house or RV as a year-round residence isn't spelled out in what I've reviewed. Don't guess here, ask the CEO directly.

Building permits and codes. MUBEC applies here, as it does statewide, and it's enforced locally by the CEO, who also handles Shoreland Zoning and the state plumbing rules.

Septic and composting toilets. This part is more settled. Maine's Subsurface Wastewater Disposal Rules (a state code, administered by the Maine CDC) govern septic design and permitting, and the town's CEO acts as the Local Plumbing Inspector who reviews and enforces it locally. That framework explicitly covers everything from pit privies to greywater disposal areas to full septic systems, so composting toilets and alternative systems aren't off the table, they just need to fit within the state rules as reviewed locally.

Greywater. Same structure as septic: state rules, local enforcement through the CEO. No separate town-specific greywater ordinance turned up in my research.

Rainwater harvesting. I found nothing specific to North Berwick on this. It's likely only touched by general state plumbing standards if you're tying rainwater into interior plumbing, but that's not confirmed, so ask the CEO.

Wells. No town-specific well ordinance surfaced. Well construction is generally a state-level matter, and I couldn't confirm whether North Berwick layers any additional local permit step on top.

Utility disconnection. No explicit ban on going off-grid from utilities came up in my research. Practically speaking, though, any occupied structure still has to satisfy MUBEC and the state wastewater rules with CEO sign-off, so "off-grid" doesn't mean "off the code books."

Bottom line: North Berwick isn't hostile to off-grid living, but it's not a place where you can assume "no zoning, no problem" either. The Code Enforcement Office is your first and most important call.
