Off-Grid Living in Kingston, New Hampshire

Kingston, New Hampshire is fully zoned, so anyone thinking about off-grid living here needs to start with the town's zoning map, not assume raw land is a blank slate. I've dug through the town's own pages and state statutes to piece together what's actually confirmed versus what's still murky.

Zoning. Kingston has a real zoning ordinance with multiple districts, Aquifer Protection, Wetlands Conservation, Shoreland Protection, Flood Plain, plus the usual residential, commercial, and industrial zones. The Zoning Board of Adjustment gets its authority from state RSAs 673, 674, 676, and 677, layered with Kingston's local ordinance. Where you land on the map matters a lot, especially if you're near wetlands or an aquifer overlay, so I'd check the town's zoning district page before assuming anything about raw-land occupancy.

Dwellings, tiny homes, RVs. Kingston does allow accessory dwelling units, and has since 2012 in its current ordinance form. An ADU built inside the existing footprint of a house needs only a building permit; one that's detached or changes the exterior needs a Conditional Use Permit from the Planning Board. I could not find anything in Kingston's official materials specifically addressing tiny homes on wheels or RVs as permanent residences, so that's not confirmed. I'd call the Planning Board directly before betting a living situation on it.

Building permits. Required, and enforced locally by the Building Inspector's office, which works to make sure construction follows the town's adopted building code.

Septic and composting toilets. Any structure with a connected water supply must have a septic system, and that goes through the state's NH Department of Environmental Services process under RSA 485-A, plus local certification that you've complied with Kingston's own requirements. If you want to skip water-carriage systems entirely, privies (outhouses) are allowed, but they need local health official approval on siting and construction, and are meant for situations with no electricity or running water.

Greywater. No Kingston-specific rule turned up in my research. This falls back to state-level ambiguity, so it's genuinely unclear, worth a direct call to NHDES or the town.

Rainwater harvesting. I found no Kingston ordinance restricting it. Indoor use would fall under the adopted state plumbing code, but nothing town-specific limits collection.

Wells. No added town restriction beyond state well rules, though if your land sits inside the Aquifer Protection District, siting could be constrained. Worth checking the zoning map for that overlay.

Off-grid / utility disconnection. The linchpin is the water-to-septic rule: if you have a connected water supply, you need a wastewater disposal system, state-mandated and locally enforced. I didn't find a separate Kingston rule forcing electric hookup, so going off-grid on power specifically looks more flexible than going off-grid on water/septic.

Bottom line: Kingston isn't hostile to off-grid ideas, but it's not a free-for-all either. Local zoning district, aquifer overlays, and the state's septic rules will shape what you can actually do.
