Off-Grid Living in Somerville, Maine

If you're eyeing a piece of land in Somerville, Maine, on the shore of Sheepscot Pond or tucked back in the woods of Lincoln County, here's what I found digging through the town's own records.

First thing to know: Somerville is not one of those unzoned Maine towns where you can just do whatever you want. The town has a Land Use Ordinance on the books (I confirmed this because the town's ordinance list references an "Appeals Board Ordinance" extracted from it), plus Shoreland Zoning, which is a state-mandated program that towns like Somerville administer locally under Maine DEP guidelines. I couldn't pull the full ordinance text off the town's site, so I can't tell you exact districts or setbacks, but the ordinance clearly exists and governs land use townwide.

Somerville runs lean, one person, the Code Enforcement Officer (also the Plumbing Inspector), handles nearly everything: land use permits, shoreland zoning, septic permitting, and internal plumbing. That's a lot of hats for one office, which actually makes it easier for you as a landowner, there's one phone number to call for most off-grid questions.

On septic: the CEO issues the HHE-200 permit, which is Maine's standard state form for subsurface wastewater systems. This covers conventional septic and, from what I can tell, alternative systems too, including composting toilet setups, since those still fall under subsurface wastewater rules administered by Maine CDC and enforced locally. I did not find a separate town rule for greywater specifically, so it likely gets folded into that same HHE-200 process, but confirm that directly with the CEO before you build anything.

Wells are permitted, and the town's own page nudges residents to get well water tested for health reasons, but I found no separate town permitting layer beyond the state's well rules. Building codes are enforced locally by the CEO, who by state law (30-A MRSA) must get certified in shoreland zoning, land use, plumbing, and subsurface wastewater within a set window of taking the job, but I could not confirm whether Somerville has locally adopted Maine's statewide building code (MUBEC).

Here's where I have to be honest about gaps: tiny homes and RVs as permanent dwellings, rainwater harvesting, and general "living off the grid, disconnected from utilities" are all things I could not find explicit town rules on. That doesn't mean they're banned, it means the town's website doesn't spell it out, and it would fall under the general Land Use Ordinance and CEO discretion. Given how much overlap Somerville's rules have with shoreland areas (a lot of the town borders water), I'd treat shoreland setbacks as a serious factor in any off-grid plan here.

My bottom line: call the CEO before you buy or build. One conversation with that office will answer more than any amount of website digging.
