Off-Grid Living in Carrabassett Valley, Maine

I've been digging into what off-grid life actually looks like in Carrabassett Valley, Maine, and the short version is: this is not "unclaimed" territory where you can just roll in and homestead quietly. It's an organized town with its own Zoning Ordinance and a separate Shoreland Zoning Ordinance, both administered locally by the Code Enforcement Officer (currently Christopher Parks) and the Planning Board. A lot of the town is undeveloped, conserved, or state/tribal land, but the parts you could actually build on are regulated.

Zoning. The town's Zoning Ordinance and Shoreland Zoning Ordinance split land into districts (General Development, Limited Residential, Resource Protection, Stream Protection). Some uses are allowed without a permit as long as you meet general land-use standards; others need sign-off from the Planning Board, the Code Enforcement Officer, or the Local Plumbing Inspector. The town has actually taken legal action over unpermitted structures and setback violations, so this isn't a paper rule, it gets enforced.

Dwellings, RVs, tiny homes. Within the shoreland zone, if you park an RV, tent, or similar shelter on a lot for more than 120 days a year, the ordinance treats it like a residential structure, meaning you need a compliant subsurface sewage system unless you're on public sewer. I did not find a separate tiny-home category in the ordinance, and I couldn't confirm whether the 120-day rule applies the same way outside the shoreland zone, so ask the CEO directly if your parcel isn't waterfront/wetland-adjacent.

Building permits. The town requires its own building permits (new construction, additions, plus a short-form option), but interestingly Carrabassett Valley is on the state's list of towns with no obligation to enforce Maine's statewide building code (MUBEC), because of its small population. That doesn't mean no rules, it means the town's own zoning and permitting process is what governs, not the state code.

Septic and composting toilets. Maine's Subsurface Wastewater Disposal Rules set the baseline statewide, and the town's Code Enforcement office (which doubles as the Local Plumbing Inspector) administers it locally, including linking out to the state's septic permit search tool. New or replacement systems generally need a permit designed by a licensed site evaluator or engineer, though there are some listed exceptions, including certain alternative toilets other than pit privies.

Greywater and wells appear to follow the state baseline with no town-specific twist that I could confirm. Rainwater harvesting I found nothing on at either level, town or state, so treat it as an open question. Full utility disconnection isn't explicitly banned, but the 120-day shoreland rule and general permitting requirements push year-round residents toward code-compliant, septic-connected structures rather than a bare-bones off-grid cabin, at least within the shoreland zone.

Bottom line: call the Code Enforcement Officer before you buy land or plan a build here. The ordinance language is specific enough that guessing wrong could mean real enforcement consequences.
