Off-Grid Living in Pittsfield, New Hampshire

Pittsfield, New Hampshire is a fully zoned town, so before you buy raw land or plan an off-grid setup here, the first thing I'd do is pull the official Zoning Ordinance and district map from the Town of Pittsfield's website and figure out which district your parcel sits in. What's allowed for a homestead varies district by district, and the Zoning Board of Adjustment is the body that handles variances or special exceptions if your plan doesn't fit neatly into the ordinance.

On dwellings: Pittsfield used to have a separate Mobile Home, Mobile Home Park and Trailer Park Ordinance, but that's been repealed and folded into the main zoning ordinance. I could not find specific language in the town's public documents addressing tiny houses on wheels or long-term RV living as a primary residence, so treat that as an open question and ask the Code Compliance Department directly. Their building permit form does list "mobile home" as a permit category, for what it's worth.

Building permits themselves are handled locally. Pittsfield's Code Compliance Department issues permits for new construction, additions, and mobile homes, which lines up with how New Hampshire generally delegates building code enforcement to municipalities under state law (RSA 155-A). Don't skip this step even if you're building small or off-grid.

Septic is where the state steps in more directly. New Hampshire's Department of Environmental Services (NHDES), through its Subsurface Systems Bureau, runs the approval process for septic systems statewide. In practice, a licensed septic Designer submits the design to the municipality for local sign-off before it goes to the state for final review. NHDES does have rules covering composting and incinerating toilets, but it's worth noting those units are meant for human waste only, they can't substitute for a full septic system if your structure has plumbed fixtures. I did not find a Pittsfield-specific composting toilet ordinance, so confirm with NHDES or the town if this is central to your plan.

Greywater reuse, rainwater harvesting, and private wells all fall mainly under state rules in New Hampshire, and I did not find any Pittsfield-specific ordinances adding restrictions on top of those baseline state provisions. Well construction is licensed through the state Water Well Board. None of this is confirmed as town-specific, so if these systems matter to your plan, it's worth a direct call to NHDES.

As for living fully off the grid, unhooked from utilities, I didn't find an explicit Pittsfield ordinance requiring utility connections. But you'll still need to go through the standard building permit process, and if you have any plumbing, an approved septic (or approved alternative) system as described above. Bottom line: Pittsfield's rules are a mix of local zoning and state environmental oversight, and several details here just weren't nailed down in the public documents I could find, so a phone call to the town offices below will save you guesswork.
