Off-Grid Living in Piermont, New Hampshire

Piermont, New Hampshire is a small, zoned town, which surprises some people who assume rural NH towns have no zoning at all. Piermont adopted a Zoning Ordinance in 2017, administered by a Zoning Administrator with a Zoning Board of Adjustment handling variances, special exceptions, and appeals. If you're eyeing land here for an off-grid setup, you're working within that framework, not a blank slate.

Zoning and land use. The Piermont Zoning Ordinance sets a minimum lot size of 1 acre and 100 feet of road frontage, plus shoreland setbacks (75 feet from a lake under Article VIII). This is town-level regulation, not a state mandate, so it's specific to Piermont.

Dwellings, tiny homes, RVs. I couldn't confirm specific rules on tiny homes, RVs, or ADUs from the sections of the ordinance I reviewed. Don't assume either way, call the Zoning Administrator before you buy a tiny house or plan to live in an RV on raw land.

Building permits. Article VI, Section 1(a) of the Zoning Ordinance requires a permit before building a residence or placing a mobile home that isn't served by an off-site sewage system. In plain terms, the town wants to know about your build before you start, including off-grid ones. Permit issuance runs through the Piermont Town Office.

Septic. This is a state matter first. New Hampshire DES rule Env-Wq 1000 requires a septic system, formally an individual sewage disposal system, for any structure that has a water supply connected and discharges wastewater on site. A licensed designer has to prepare the application, and locally, that design gets routed through the municipality for approval before going to the state. Composting toilets aren't clearly addressed in what I found at either the state or town level, so if that's your plan, ask both NHDES and the Piermont Town Office directly.

Greywater and rainwater. I found no Piermont-specific ordinance on either. That likely means you're working from whatever baseline New Hampshire's plumbing and residential codes set statewide, but I couldn't pin down a specific state greywater rule either. Treat this as unconfirmed and worth a direct call.

Wells. No town-specific well ordinance turned up. Private wells in NH fall under the state Water Well Board (RSA 482-B), which licenses well drillers and sets construction standards statewide.

Utility disconnection. Piermont doesn't appear to ban off-grid living outright. The ordinance's permit trigger for homes "not serviced by an off-site sewage system" actually suggests the town anticipates and accommodates septic-served, utility-disconnected homes, just with a permit and, per the state, a compliant septic system if you have running water.

Bottom line: Piermont is workable for off-grid living, but it's zoned, and building or installing a home here means a town permit plus, in most cases, a state-approved septic design. Confirm the gray areas, tiny homes, RVs, greywater, and composting toilets, directly with the town before committing.
