Off-Grid Living in North Yarmouth, Maine

North Yarmouth is a zoned town, not a rural free-for-all, and that fact shapes everything about off-grid living here. Below is what I found researching this specific town in Maine, with the caveat that I'm not a lawyer and you should confirm details before you build or buy.

Zoning. The town runs its own Land Use Ordinance (first adopted back in 2005, amended since) with a Planning Board that reviews development against both the local ordinance and applicable Maine statutes. A Code Enforcement Officer (CEO) enforces the ordinance and can order you to stop an illegal use of land. This is a home-rule town, so don't assume "rural" means unregulated.

Dwellings, tiny homes, RVs. North Yarmouth's own permit chart requires Building, Electrical, Plumbing, and Road Ordinance permits for new single-family homes, multi-family buildings, and additional dwelling units. You also need a Certificate of Occupancy before you can legally live in a structure, and the CEO tracks these on record. I did not find a town-specific rule on tiny homes or RVs as permanent residences, so if that's your plan, call the CEO's office directly and ask how it fits (or doesn't) under the current ordinance.

Building permits. The CEO's office issues all building, electrical, and plumbing permits and inspects work afterward for health and safety. There's a small administrative fee attached to permits per the town's own permit page, but I didn't confirm which statewide building code (MUBEC or otherwise) the town has formally adopted, so ask the CEO.

Septic and composting toilets. This is state-driven: Maine's Subsurface Wastewater Disposal Rules (administered by Maine CDC) require you to prove to the municipality that any planned wastewater system will comply before you're allowed to build a structure needing one. Locally, North Yarmouth's CEO doubles as the Local Plumbing Inspector (LPI), reviewing and issuing septic permits. Portable toilets are limited to short-term use (state rule caps it at about a week) unless the LPI signs off on something longer.

Greywater. Maine folds greywater into the same subsurface wastewater rules as septic, enforced through the LPI. I found no separate North Yarmouth greywater exception, so assume it's regulated like any other wastewater discharge.

Rainwater harvesting. I could not find any North Yarmouth ordinance or Maine state rule specifically addressing rainwater collection. That doesn't mean it's banned, it just means it's not confirmed either way, so this is a good question for the CEO.

Wells. No town-specific well ordinance turned up in my research. Maine's Water Well Commission sets statewide well construction and siting standards, and that would apply here by default.

Off-grid/utility disconnection generally. I found nothing in North Yarmouth's ordinance that explicitly addresses living disconnected from the electric grid or municipal utilities. In practice, your building, septic, and well permits are the levers the town actually uses to regulate how you live on a property.

Bottom line: North Yarmouth is permit-driven at both the state and town level, and the CEO's office is your single best contact for nearly every question above.
