Off-Grid Living in Westport Island, Maine

I've been digging into Westport Island, Maine for folks dreaming about a quieter, more self-reliant life on this little peninsula town in Lincoln County. Here's what my research turned up, and where I'd tell you to stop reading me and start calling the town.

First, a myth-buster: Westport Island is NOT unzoned. I see this town lumped in with "off-grid friendly, no zoning" lists sometimes, but that's wrong. The town runs its land use through a stack of ordinances, a Building Code Ordinance, a Shoreland Zoning Ordinance, a Minimum Lot Size Ordinance, Site Plan Review, Subdivision, Cluster Residential Development, and Flood Plain Management, all administered by the town's Code Enforcement Officer (CEO). There isn't a single ordinance called "Zoning Ordinance" by name, but don't mistake that for an absence of rules.

On raw land, before you do anything, put in a driveway, run power, build a shed, the town's own guidance says the first step is a driveway permit, then getting an E-911 address, then whatever other permits your project needs. That's true whether you're building a full house or something more modest and off-grid.

Tiny homes and RVs as full-time dwellings aren't spelled out separately in what I found. The Building Code Ordinance covers new home construction, modular and relocated mobile homes, sheds, garages, decks, and additions, but it's silent on tiny houses and RV living specifically. I'd call the CEO directly before assuming either path is smooth.

Building generally is regulated locally under that Building Code Ordinance, and if you're within 250 feet of a lake, pond, river, stream, or wetland, Shoreland Zoning permitting kicks in too, covering building projects, additions, and new accessory structures. Normal repair and maintenance of existing structures doesn't need a permit.

For septic and composting toilets, Maine's Subsurface Wastewater Disposal Rules (state-level, administered through the Maine CDC) set the baseline, and Westport Island's Local Plumbing Inspector enforces those rules locally. Greywater looks to fall under this same state rulebook since I couldn't find a separate town greywater ordinance, so check with the Plumbing Inspector or CEO to be sure.

Rainwater harvesting: I found no town ordinance addressing it either way, which usually means it's allowed but worth a quick confirming call. Private wells are similarly not covered by a town ordinance in what I found, they're governed by state well-construction standards, not town rules.

Living disconnected from utilities isn't called out as its own regulated category, but since any structure needs that driveway permit and E-911 address before other permits, and since septic and building sign-offs are required regardless of grid connection, going off-grid doesn't let you skip the town's permitting sequence.

Bottom line: Westport Island has more local structure than a lot of "off-grid" hopefuls expect. Confirm everything with the CEO before you buy land or break ground.
