Off-Grid Living in Camden, Maine

If you're eyeing Camden, Maine for an off-grid setup, the first thing I want you to understand is that Camden is a fully zoned town, not one of Maine's unorganized territories where you have a lot more freedom. Camden's Zoning Ordinance (Chapter 290 of the Town Code) divides the town into districts, like Harbor Business, Natural Resource Protection, and various residential districts, each with its own list of allowed and prohibited uses. The town's Code Enforcement Officer (CEO) makes zoning calls day to day, and a Zoning Board of Appeals handles disputes and special exceptions. So the honest answer to "can I do X here" is almost always "it depends on which district your parcel sits in," and I'd confirm that with the CEO before buying land.

On dwellings: I didn't find a dedicated tiny-home or RV-as-permanent-residence provision in the ordinance sections I reviewed. What I did find is Maine's statewide MUBEC "seasonal dwelling" exemption, which the CEO may apply locally. That path caps you at 750 square feet, no central heat, no year-round septic system, and 100-amp electrical service, with owner-occupancy required. It's a real option for a minimal off-grid structure, but it comes with real limits, not a workaround for a full-time home with conventional systems.

Building permits are required, full stop, administered by the CEO under both the local ordinance and the state's Maine Uniform Building and Energy Code. You'll need a certificate of occupancy before you can legally use a structure, and that certificate only issues once the building, site, and any related systems (septic, plumbing, electrical) are shown to comply. Septic is permitted but requires a permit through Camden's Local Plumbing Inspector role (handled by the CEO), layered on top of Maine's statewide Subsurface Wastewater rules administered by Maine CDC. If you're in the shoreland zone and the property changes hands, state law (30-A MRS §4216) triggers a mandatory septic inspection by a certified inspector.

Greywater reuse looks to be permitted in principle, folded into the same state wastewater rules and local plumbing permit process, but I didn't find a Camden-specific greywater ordinance. Rainwater harvesting is genuinely unclear. I found no town or state rule addressing it directly. Private wells appear permitted, governed at the state level with no Camden-specific well ordinance turned up, though connecting a well to a structure would still run through the CEO's building/plumbing permitting.

Living fully off-grid, disconnected from municipal utilities, isn't explicitly banned in what I reviewed, but it's indirectly constrained: your certificate of occupancy depends on meeting the zoning, building, and septic requirements, so you can't just skip those systems and expect the town to sign off. Bottom line: Camden allows off-grid-style living, but only within its permitting framework, not outside it.
