Off-Grid Living in Deerfield, New Hampshire

Deerfield, New Hampshire is a zoned town, which surprises some people who assume rural New Hampshire is a free-for-all. It isn't. The Town has an adopted Zoning Ordinance, a Building Inspector/Code Enforcement Officer who administers it, a Zoning Board of Adjustment for variances and appeals, and a Planning Board for subdivisions and driveways. So if you're picturing buying a back lot and quietly living off-grid with no paperwork, Deerfield's rules push against that.

Zoning and raw land. The Zoning Ordinance sets up districts (Agricultural/Residential, Commercial/Industrial Overlay, etc.) with their own standards, and the Zoning Board of Adjustment can grant variances or special exceptions. I didn't find anything in the town's public materials that separately addresses just living on raw, undeveloped land without a permitted structure, so treat that as unclear and confirm with the Building Inspector.

Dwellings, tiny homes, RVs. Deerfield's ordinance covers dwelling construction generally, including a provision for senior/elderly housing in the Agricultural/Residential zone. I could not find specific language on tiny houses on wheels or RVs used as permanent dwellings, so that's an open question, again one to run past the Building Inspector before you buy or build.

Building permits. These are required and locally enforced. The Building Inspector has a defined window to act on an application under the town's ordinance. Before a new dwelling permit is finalized, the town wants proof of state septic approval, an approved driveway permit from the Planning Board, and impact fee sign-off, plus at final inspection a satisfactory water test and the state's septic Operation Certificate.

Septic. This is a state matter first: NH DES's Subsurface Systems Bureau has to approve septic system design before installation, and issues both a Construction approval and an Operation approval. Deerfield's own permit checklist requires copies of both before a certificate of occupancy is signed off locally. Composting toilets aren't addressed in anything I found from the town, so that's not confirmed either way.

Greywater and rainwater. I found no Deerfield-specific ordinance on greywater reuse or rainwater harvesting. That likely means the state's general building and plumbing code baseline applies, but there's no local text spelling out details, so ask the Building Inspector directly if you're planning a greywater or catchment system.

Wells. Private wells fall under the state's well construction licensing program, and Deerfield's own building final-inspection checklist requires a satisfactory water test before the town will sign off on occupancy.

Living off-grid generally. Nothing I found bans it outright, but the practical effect of the town's permitting chain (septic approval, water test, building permit, driveway permit) is that a legally occupied dwelling has to meet those baseline infrastructure requirements even without municipal utility hookups, which Deerfield mostly doesn't have anyway.

Bottom line: Deerfield isn't hostile to off-grid living, but it isn't unregulated either. The town leans on the state for septic and well approvals and layers its own building and driveway permitting on top. Call before you commit to land.
