I've been digging into Alton, New Hampshire for folks considering off-grid or self-sufficient living here, and here's the honest picture based on the town's own documents and state law.
Zoning is real here, and it matters. Alton adopted its zoning ordinance back in 1970 under New Hampshire's RSA Title LXIV, and the town keeps amending it (most recently 2024-2025 town meeting cycles). The town is broken into districts like Lakeshore Residential, Residential Rural, and Rural, each with its own rules. Recent amendments spell out that a single-family dwelling needs a minimum of one acre and you're limited to one per lot. I didn't find anything in the ordinance that clearly addresses just occupying raw, vacant land without a permitted dwelling, so if that's your plan, call the Planning Department before you commit to anything.
Tiny homes and RVs are restricted, not banned. The ordinance has specific sections for recreational campgrounds, RVs, "recreational camping cabins," and manufactured homes, including temporary manufactured home use and an accessory manufactured home option for a relative with a health issue. Alton also allows accessory dwelling units (ADUs) by Special Exception, but the town's ordinance and state ADU law (per NH RSA 674:31) mean you generally can't stack an ADU with certain manufactured housing or multiple dwelling types on the same lot. If you're picturing a tiny house on wheels as your only residence, get the Zoning Administrator's take first.
Building permits are required and locally enforced. Alton's Code Official (who wears three hats: Building Inspector, Zoning Administrator, and Health Officer) handles building, electrical, plumbing, and gas permits. Propane tank burial and oil burner permits go through the Fire Department instead. The town says complete applications typically move within a business-week or two, but confirm current processing directly with the Building Department.
Septic is state-driven. New Hampshire's DES Subsurface Systems Bureau sets the baseline for septic approvals statewide, and Alton's local ordinance leans on those same DES health regulations for manufactured and recreational parks. I did not find a separate Alton composting-toilet rule, so treat that as unconfirmed and ask the Health Officer directly.
Greywater and rainwater harvesting are genuinely unclear. I couldn't find any Alton-specific ordinance addressing either one, which means you're working off New Hampshire's general (and itself somewhat murky) state baseline. Don't assume silence means permission, ask before you build a greywater system.
Wells fall under the state. New Hampshire's Water Well Board regulates well construction statewide (RSA 482-B); Alton's own building permit process just requires referencing approved septic and well plans as part of your plot plan.
Full utility disconnection isn't explicitly banned, but between the one-dwelling-per-acre rule, mandatory building permits, and septic/well compliance, Alton's system is built around a permitted, inspected dwelling, not informal off-grid squatting. </body_md> <summary>Alton, NH is a zoned town with real permitting requirements for dwellings, septic, and building work, and while there's no outright ban on off-grid living, most of the specifics (raw-land occupancy, greywater, rainwater) aren't clearly addressed and need direct confirmation from town offices.</summary>

FAQ
Common questions about off-grid living in Alton
Is it legal to live off-grid in Alton, New Hampshire?
There is no outright ban on living off-grid in Alton, New Hampshire - it is legal but regulated. Zoning and land use are restricted, putting a cabin, tiny home, or RV on raw land is restricted, and building permits are generally allowed. Plan around septic/wastewater (set locally and vary by area) and disconnecting from utilities (set locally and vary by area). Because these rules are set locally, confirm the specifics with Alton before you buy land or build.
Can I live off-grid on vacant land in Alton without building a permitted structure?
I couldn't find anything in Alton's zoning ordinance that clearly allows or bans just occupying raw land without a permitted dwelling. Given the town's one-dwelling-per-acre rule and permitting requirements, I'd call the Planning Department before assuming this is fine.
Can I put a tiny house or RV on my land as a permanent home?
Alton's ordinance treats RVs, camping cabins, and manufactured homes as distinct categories with their own standards, mostly geared toward temporary or accessory use, not as a stand-alone permanent residence. Talk to the Zoning Administrator before assuming a tiny home on wheels qualifies as your primary dwelling.
Does Alton allow composting toilets instead of a septic system?
I found no Alton-specific composting toilet ordinance. Septic approvals run through NH DES statewide, and I'd confirm with Alton's Health Officer whether an alternative system would be accepted locally.
Is rainwater harvesting legal in Alton?
There's no Alton-specific rule on this that I found, and New Hampshire's own statewide guidance is limited. It's worth a call to the Building Department before setting up a collection system, especially if it's meant for household use.
Who do I actually call with questions in Alton?
The Building Department doubles as the Zoning Administrator's office and the Health Officer's office, so for most off-grid questions, that's your one-stop call. For land use and subdivision questions, the Planning Department is the better first call.
