Off-Grid Living in Errol, New Hampshire

I've been digging into Errol, New Hampshire for anyone dreaming of a quiet off-grid spot up near the Maine border, and the first thing I need to flag is a big recent change: Errol is no longer unzoned. For a long time this town had the reputation of being one of the last "wide open" places in NH, but the town adopted a formal Zoning Ordinance in 2024, joining the large majority of NH municipalities that have zoning. If you're relying on old forum posts or outdated info about Errol having no zoning, please toss that assumption out. The Town of Errol hosts its Zoning Ordinance directly on errolnh.org, and there's an active Planning Board reviewing applications, lot line adjustments, and site plans.

That said, I want to be straight with you about the limits of what I could verify. I could confirm the ordinance exists and that the town has real zoning authority now, but I could not pull the specific district maps, dimensional standards, or permitted-use lists from the document in my research. So for questions like "can I put a tiny home or RV on my land," I genuinely don't know the answer yet, and neither should you assume one way or the other. Call the Errol Town Office or Planning Board before you buy or build.

Building permits in New Hampshire are a two-layer system: the state sets a base code (this authority comes from RSA 155-A:2, III), but enforcement and permit issuance happen locally. Errol's Town Office is your point of contact, though I couldn't confirm specific fees or process steps, so ask them directly.

For septic and composting toilets, Errol doesn't appear to have its own local health ordinance beyond the state framework. That means the NH Department of Environmental Services Subsurface Systems Bureau rules apply, same as most of the state. Greywater reuse is murky both at the state and town level, there's no dedicated residential greywater rule I could find anywhere, so treat this as unclear territory and ask NH DES directly before doing anything.

Rainwater harvesting looks fine, I found no Errol-specific restriction, and state plumbing code provisions would govern generally. Private wells are handled at the state level too, under the NH Water Well Board (RSA 482-B), with no additional Errol-specific well ordinance turning up in my research.

The question I get asked most, "can I legally live completely off-grid, disconnected from utilities," is one I can't fully answer for Errol. I found no health ordinance or subdivision rule mandating utility hookups, and given the town's small size, mandatory hookup rules seem less likely than in a denser suburb, but this isn't officially confirmed. Don't take my hunch as legal clearance, call the Town Office.

Bottom line: Errol just became a zoned town, so the old "Wild West" reputation is out of date, and a lot of the specific homesteading questions need a direct call to town hall to nail down.
