Off-Grid Living in Ashland, New Hampshire

I've been digging into Ashland, New Hampshire, for anyone thinking about a more self-sufficient or off-grid setup here, and the short version is: this is a zoned town, not one of those wide-open unzoned New Hampshire spots. That changes the calculus a fair bit.

Zoning. Ashland's Planning Board maintains a zoning ordinance (last amended March 11, 2025) with four base districts, Village Residential, Rural Residential, Commercial, and Industrial-Commercial, plus overlay districts including a Groundwater Protection overlay. What you can do with raw land depends entirely on which district it sits in. Personal residences are specifically barred from the Industrial-Commercial zone, and junk yards are prohibited town-wide. If you're eyeing a parcel, I'd pull up the permitted-use table for that specific zone before assuming anything is allowed.

Dwellings, tiny homes, RVs. The ordinance speaks directly to mobile homes: outside designated mobile home parks, they're only allowed by special exception, and each home needs its own marked lot meeting a minimum size (10,000 square feet in Village Residential). I did not find language specifically addressing tiny houses on wheels or RVs as permanent residences, so treat that as an open question for the Building Inspector or Zoning Board of Adjustment rather than something settled in writing.

Building permits. These are handled locally. Ashland's Building Inspector issues and denies permits for building, electrical, plumbing, driveway, heating, roofing, demolition, and foundation work, checking against both the zoning ordinance and state and town regulations. Basically nothing gets built here without that office's sign-off.

Septic. The town's 2025 Article 4 revisions point to the New Hampshire Department of Environmental Services for wastewater matters, and DES's Env-Wq 1000 rules are the real controlling framework for any subsurface system statewide. Interestingly, the ordinance says a separate septic system isn't required for an accessory dwelling unit sharing a lot with a principal dwelling, which is a nice bit of flexibility for anyone building a small second unit. Composting toilets aren't addressed in what I found in the town ordinance, so that's a state DES question.

Greywater and rainwater. I couldn't find any Ashland-specific rule on either. New Hampshire doesn't have a clear statewide residential greywater standard either, so this sits in genuinely unclear territory, confirm directly with DES or the town before building a greywater system. Rainwater harvesting would default to whatever the state's adopted plumbing code says, absent a local amendment.

Wells. Nothing in the ordinance excerpts I reviewed restricts private wells outright, but the Groundwater Protection overlay (Article 9B) likely imposes siting standards near aquifers and wellheads, so check with Planning if you're near that overlay.

Utility disconnection. I found no Ashland rule forcing a hookup to municipal water or sewer as a condition of occupancy. That said, your dwelling still has to clear Building Inspector and Health Officer review regardless of how it's powered or plumbed.

Bottom line: Ashland gives you more structure than an unzoned town, so lean on the Planning Board and Building Inspector early and often.
