Off-Grid Living in Canaan, New Hampshire

I've spent a fair bit of time digging into Canaan, New Hampshire because it's one of the more unusual towns in the state for off-grid purposes: it's unzoned. That word gets thrown around loosely sometimes, so let me be precise about what it means here and what it doesn't.

Zoning. Canaan has no comprehensive zoning ordinance. Voters have actually rejected zoning proposals at town meeting (a historic district building-type ordinance was voted down 327-204), so this isn't an oversight, it's a community choice. Without zoning, there are no residential or commercial districts and no minimum lot size beyond what your intended use requires. That said, the Canaan Planning Board still administers subdivision, site plan, excavation, and driveway regulations, and there's a Floodplain Ordinance that applies if you're in a flood-prone area. Unzoned doesn't mean unregulated.

Dwellings, tiny homes, RVs. Because there's no zoning, there's no district rule saying "no tiny homes here" or "RVs can't be permanent residences." But the town's Building Inspector still requires a permit for structures, including a second dwelling on a lot. Whether a standalone tiny house or RV as a full-time residence is treated differently wasn't something I could confirm from Canaan's official pages, so I'd call the Building Inspector's office before you commit to a plan.

Building permits. Yes, you need one, administered locally by the Building Inspector/Floodplain Administrator. That office also flags whether you need Historic District Commission review, a driveway permit from the Highway Department, or Planning Board site plan approval, and advises on state permits like septic design.

Septic and composting toilets. This one's set at the state level, not the town. Under New Hampshire's RSA 485-A and the Env-Wq 1000 rules (administered by NH DES), any structure with plumbed fixtures, sink, toilet, shower, needs to connect to a septic system or sewer, regardless of your water source. Composting or incinerating toilets are allowed for human waste only, and NHDES has rules for them, but they can't substitute for a septic system if you've got plumbing. Canaan's Building Inspector keeps septic design files locally, but the design itself goes through NHDES.

Greywater and rainwater. I couldn't find a Canaan-specific ordinance on either, and the state picture is ambiguous enough that I'm marking both unclear. Ask the Building Inspector or NHDES directly before building a system around either.

Wells. Well construction is licensed at the state level. Canaan itself has a Source Water Protection Committee and a drinking water protection group under its Planning Board, showing local interest in water quality, but I didn't find a separate town well ordinance.

Utility disconnection. No ordinance mandating hookup to municipal water or sewer turned up in my research, and there's no municipal system to speak of in most of town anyway. But going off-grid doesn't excuse you from the building permit and, if applicable, septic requirements above.

Bottom line: Canaan gives you real freedom on land use because it's unzoned, but state septic law and local building permit requirements still apply in full force.
