Off-Grid Living in Cape Elizabeth, Maine

Cape Elizabeth, Maine is a fully zoned town, so if you're picturing off-grid living here, the first thing to accept is that the town's Zoning Ordinance (Chapter 19 of the Town Code) applies to your land, and the Code Enforcement Officer administers it. This is not one of those unzoned rural pockets where you can just do your own thing. There are Resource Protection zones with their own permit requirements, and if your lot doesn't have real frontage on a town-accepted road (private road frontage only, or no frontage), the Code Enforcement Officer or the Planning Board has to review it before any building permit gets issued.

On dwellings, I couldn't find Cape Elizabeth-specific language addressing tiny homes or RVs as permanent residences. The town's permitting and certificate-of-occupancy process runs through the Maine Uniform Building and Energy Code (MUBEC), which the state adopted under Title 10, chapter 1103, but how that code treats a tiny home or RV as a permanent dwelling isn't something I can confirm from what's published. Call Code Enforcement before you commit to either option.

Building permits themselves are squarely regulated, MUBEC applies as of the state's effective date, along with the 2003 ICC International Fire Code and the current National Electrical Code. Permits now run through the town's online system called GovWell.

Septic is where Maine state rules do a lot of the work. The state's Subsurface Wastewater Disposal Rules (Chapter 241) govern septic systems and also allow non-discharging composting-style toilets, but you still need a Waste Water Disposal Permit through Cape Elizabeth's Code Enforcement office, which acts as the Local Plumbing Inspector. Greywater systems fall under that same Chapter 241 framework: a licensed site evaluator has to complete the application, and the town issues the permit locally.

Private wells are essentially unregulated at the state and local level beyond basic guidance, the Maine CDC just recommends owners test and treat their own water; I found no Cape Elizabeth well ordinance.

Two areas remain genuinely unclear from the sources I reviewed: rainwater harvesting (no town ordinance found either way) and living fully disconnected from utilities (no standalone rule, though it would likely surface indirectly through the building permit and certificate-of-occupancy process). For both, your safest move is a direct call to Code Enforcement before you plan around an assumption.

Bottom line: Cape Elizabeth isn't hostile to off-grid systems like septic alternatives or greywater reuse, but almost everything routes through the Code Enforcement Officer, and the zoning ordinance means your land's district and road frontage matter a lot before you even get to plumbing.
