Off-Grid Living in Swanzey, New Hampshire

I've been digging into what off-grid living actually looks like in Swanzey, New Hampshire, and the short answer is: it's zoned, it's regulated, but it's still very workable if you understand which authority controls what.

Zoning is real here. Swanzey is not one of those unzoned New England towns. The Town runs its own Zoning Ordinance under state authority (RSA 674), with districts like Rural/Agricultural, Residence, Business, and Commercial/Industrial, enforced by the Planning Board and Zoning Board of Adjustment. That matters because raw-land occupancy rules, like frontage requirements and minimum lot sizes, differ by district. I found a documented case where a landowner needed a variance because a parcel in the Rural/Agricultural district lacked the required road frontage. Outside the Rural/Ag district, the town generally asks for a minimum one-acre lot. Before you buy raw land here, confirm the district and its specific frontage/lot rules with the Planning Department.

Building permits are required, full stop. Swanzey has adopted the statewide New Hampshire building code (under RSA 155-A), so anything you build, from a house to a detached shed to new plumbing or electrical, needs a permit and has to meet current state code. The Code Enforcement Officer handles this, and if you disagree with a decision, you appeal to the Zoning Board of Adjustment.

Tiny homes and RVs as full-time dwellings are a gray area in my research. I couldn't find a Swanzey-specific ordinance addressing RVs or tiny houses as permanent residences. The state's manufactured housing definition (RSA 674:31) exists, but how Swanzey treats an RV-as-dwelling on a permanent basis isn't confirmed. Call the Planning or Code Enforcement office before you count on this.

Septic is state-controlled. Any septic system design and installation has to go through NH DES's Subsurface Systems Bureau, with Swanzey's local Health Officer involved at inspection. Composting toilets don't have a town-specific ordinance that I found, but state law does allow privies (non-water outhouses) if the local health officer approves the location and construction and groundwater isn't threatened.

Greywater reuse has no dedicated town or state rule that I could confirm, it's genuinely unclear, so ask the Health Officer directly.

Rainwater harvesting looks fine, no town or state restriction turned up in my research, though your setup will still fall under the general plumbing code umbrella.

Wells are permitted and common, especially since municipal water and sewer only reach West Swanzey Village. Outside that service area, private wells and septic are the norm, meaning full utility disconnection is realistic in most of the town's more rural stretches. NH DES recommends testing well water every three to five years, and Swanzey's Health Officer has run well-testing outreach after flooding.

Bottom line on utilities: if you're outside the West Swanzey Village service area, going off-grid on water and sewer is not just tolerated, it's the existing norm.
