Off-Grid Living in Dexter, Maine

I've been digging into what off-grid living actually looks like in Dexter, Maine, and here's my honest read after going through the town's own documents and the state rules that back them up.

Dexter is a zoned town, not open countryside where you can do whatever you want with raw land. The Town of Dexter maintains its own Land Use ordinance, a separate Shoreland Zoning ordinance, and a zoning map, all administered locally. I could not pull the actual district-by-district rules (setbacks, minimum lot sizes, what's allowed where) from the search, so if you're eyeing a specific parcel, that's a call to the Dexter Code Enforcement Office, not a guess on my part.

On dwellings, I couldn't confirm how Dexter treats tiny homes or RVs as permanent residences. That's a gap in what's publicly indexed, and it would fall under the town's Housing or Land Use ordinance and however the Code Enforcement Office chooses to interpret it. Don't assume either way, ask directly.

Building permits are definitely required in Dexter. I found confirmation that flood-plain construction carries its own application on top of standard permit fees, which tells me there's a working permit system through the Code Enforcement Office, though I don't have the general fee schedule or whether Dexter has adopted the state's MUBEC code specifically.

Septic and composting toilets are handled through Maine's statewide system: every town, Dexter included, is required to have a Local Plumbing Inspector (LPI), appointed locally but licensed by the state, who reviews and approves subsurface wastewater permits. This same framework covers pit privies and greywater disposal areas, so composting toilets and greywater reuse both fall under that same state-set, town-administered process. You'd apply through Dexter's Code Enforcement office, which handles LPI functions.

Rainwater harvesting: I found nothing specific to Dexter or Maine generally restricting it, but I also found nothing explicitly permitting it outside general plumbing code concerns if it ties into a building's water system. Call it unconfirmed.

Private wells follow Maine's statewide well construction standards through the Water Well Commission. I didn't find a Dexter-specific well ordinance, which suggests the town just defers to the state baseline, but that's worth confirming.

Living fully off-grid, disconnected from utilities, doesn't appear to be directly banned in any Dexter ordinance I could find. Any friction would come indirectly, through the building permit and septic permitting process, rather than a flat prohibition.

Bottom line: Dexter isn't hostile to off-grid living, but it's also not a rules-free zone. The zoning, building, and septic/plumbing pieces are all real and locally enforced, even where I couldn't pin down every specific number or timeline.
