Off-Grid Living in Caswell, Maine

I'll be upfront: Caswell, Maine is one of the toughest little towns I've tried to research for this site. It's a small, rural incorporated town in Aroostook County (population under 300), and I could not find a published zoning ordinance, land use ordinance, or even a general town website with code pages. What I did find is Caswell's basic listing on Maine.gov's town directory, and that's about it as far as official Caswell-specific documentation.

That absence of information is itself informative, but I want to be careful not to overstate it. Maine is a home-rule state, meaning towns can pass their own ordinances on anything municipal that doesn't conflict with state law, so Caswell could have a zoning or building ordinance I simply haven't located online, or it could genuinely have none. Many small Maine towns of this size stay unzoned or only lightly regulate land use. Until someone at the Caswell Town Office confirms it one way or the other, I'm marking zoning, dwelling/RV rules, building permits, rainwater harvesting, and utility disconnection as unclear or not confirmed. A commercial directory claims Caswell requires building permits through the town office, but that's not an official source, so I won't treat it as settled.

Where I can give you firmer ground is septic and greywater. Every municipality in Maine, Caswell included, is required by the state to have a Local Plumbing Inspector (LPI) who administers Maine's Subsurface Wastewater Disposal Rules, set by the Maine Department of Environmental Protection and Maine CDC. That LPI reviews and approves septic system permits, inspects installations, and enforces the state rules locally. Composting toilets and alternative systems fall under this same statewide framework. I found no Caswell-specific tweak to these rules, so the state baseline applies. Greywater disposal works the same way, administered locally by the LPI under state rules.

Private wells are governed by Maine's general well construction rules at the state level; I found nothing Caswell-specific layered on top. Rainwater harvesting isn't addressed by any state or Caswell rule I could locate, so I'd call it wide open, but not officially confirmed as unregulated.

Bottom line for anyone eyeing land in Caswell: the septic and well framework is genuinely state-standardized and reasonably clear. Everything about zoning, dwelling types, RVs, and building permits requires a direct call to the Caswell Town Office, since I could not verify these through any official ordinance text. Don't rely on secondhand directories for this one.
