Off-Grid Living in Effingham, New Hampshire

Effingham, New Hampshire is a small Carroll County town, and I want to be upfront: it is zoned. Effingham adopted its zoning ordinance under the state's enabling law (NH RSA 674, Section 16), and the town backs that up with a Zoning Board of Adjustment, a Planning Board, and Site Plan Review Regulations. So if you're picturing Effingham as some unregulated backwoods where you can just put a camper on a lot and call it home, that's not the reality on paper.

Zoning and raw land. Per the town's zoning ordinance, no structure can go up and no land use can start except as authorized by the ordinance, with permits secured first. The Planning Board also restricts building on land it considers unsuitable, flood-prone parcels, wetlands, high water table areas, steep slopes, and exposed ledge. If your off-grid dream lot has any of those features, expect scrutiny.

Dwellings, tiny homes, RVs. The town treats these as distinct permit categories rather than a free-for-all. I found references to a Building Permit Application for Campsites, an RV Info Sheet, an RV Temporary Occupancy Permit, a Seasonal Use RV Permit, and a separate Accessory Dwelling Unit checklist. That's a lot of paperwork forks, and I couldn't pin down exact placement or duration rules from what's published online, so this is one to call the Zoning Enforcement Officer about directly.

Building permits. Required locally, and structures must also comply with Effingham's Health Ordinance. The town publishes a residential permit application, a nonresidential/multifamily version, and even a "permit flow chart" to show the sequence of approvals.

Septic and composting toilets. This one's state-driven. New or replacement septic (ISDS) systems need NH Department of Environmental Services approval before Effingham will issue a building permit. Good news for off-gridders: composting and incinerating toilets are explicitly exempt from the state's septic law, per NH DES.

Greywater and rainwater. I didn't find any Effingham-specific rules on either. State guidance treats greywater systems as separate from septic law, but nothing town-level surfaced, so treat this as unclear and confirm locally if you're doing anything beyond simple household reuse.

Wells. These fall under the state's Water Well Board framework (RSA 482-B). Effingham's zoning ordinance does flag NHDES shoreland jurisdiction (RSA 483-B) for work within 250 feet of certain water bodies, requiring state approval before a town permit issues, but I found no separate town well ordinance.

Utility disconnection. No standalone rule bans going off-grid on power or water. But indirectly, the Health Ordinance and septic approval requirements kick in if you convert a place from seasonal to year-round use or add load to a system, which can functionally slow down a fully disconnected setup.

Bottom line: state rules set the floor here, especially for septic, wells, and composting toilets, but Effingham's own zoning and health ordinances add real local layers on top. Don't skip the phone call to the town before you buy land or move in.
