Off-Grid Living in Hudson, Maine

Hudson, Maine is a small town in Penobscot County, and I want to be upfront about one thing right away: this is NOT one of Maine's unorganized, unzoned townships. Hudson has its own Land Use Ordinance (adopted 1993, town-issued), a separate Shoreland Zoning Ordinance, and a Building Notification Ordinance, so anyone planning an off-grid setup here is working within actual local rules, not a regulatory vacuum.

Zoning. The Town of Hudson uses a "performance zoning" approach in its Land Use Ordinance, meaning a use is allowed on a parcel if it meets the performance standards for that district, per the official zoning map. The building permit application also lays out minimum lot sizes, generally 2 acres with 200 feet of frontage, except in the VR district where it drops to 1 acre / 150 feet. So raw land occupancy is possible, but you're inside a district system, not off in the unorganized territory.

Dwellings. The town sets a minimum dwelling size (300 sq ft for a one-bedroom unit, plus 150 sq ft per added bedroom) through the building permit process. I didn't find a specific tiny-house or RV-as-permanent-residence rule, so if that's your plan, I'd call the Code Enforcement Officer directly to ask how they'd classify it.

Building permits. Hudson's Building Notification Ordinance requires a permit application, from the Town Office, before starting construction on anything counted as a "structure" (over 100 sq ft or over a stated construction value). The same office, through its CEO, enforces state plumbing law too.

Septic and holding tanks. Hudson's CEO doubles as the town's Licensed Plumbing Inspector, so septic and wastewater permitting run through one office. Maine's statewide Subsurface Wastewater Disposal Rules govern the technical side. Notably, Hudson has its own Holding Tank Ordinance, which state rules require before holding tanks can even be used for new residential development, with the town then responsible for oversight. Composting or alternative toilets are addressed under the state rules referenced by the town's ordinance.

Greywater and rainwater. I found no Hudson-specific ordinance on either topic. Greywater likely falls under the same state subsurface wastewater rules the town enforces; rainwater harvesting isn't mentioned anywhere in Hudson's ordinance list, so treat it as unaddressed rather than approved or banned.

Wells. No town-specific well ordinance turned up. Hudson appears to lean on the state's well-setback standards (referenced in the wastewater rules) rather than writing its own.

Off-grid / disconnected from utilities. Nothing in Hudson's ordinances bans living off municipal utilities outright, but you'll still need to clear the building permit and wastewater disposal requirements regardless of whether you're tied into power or water lines.

Bottom line: Hudson is workable for off-grid living, but it's a zoned town with real paperwork, permits, and a holding-tank framework you need to follow. Call the Town Office and Code Enforcement Officer before you buy land or start building.
