Off-Grid Living in Northfield, New Hampshire

I've been digging through Northfield, New Hampshire's town documents and the state septic rules to figure out what off-grid living actually looks like here, and the short version is: Northfield is a zoned town with real requirements, so "off-grid" doesn't mean "off the radar."

Zoning and land use. Northfield has an adopted Zoning Ordinance, Subdivision Regulations, and a mapped Groundwater Protection District overlay, since the town sits over a shared aquifer it wants to protect. New construction, land use changes, and subdivisions all go through the town's Land Use Administrator, who coordinates the Planning Board and Zoning Board of Adjustment. If your land falls in the Groundwater Protection District, expect extra performance standards.

Dwellings, RVs, and tiny homes. This is where I'd slow down if you're picturing a camper on raw land. Northfield's ordinance allows residents to store a single travel trailer or camper on their own property when not in use, but only if it stays mobile, isn't hooked up to utilities, and isn't lived in. That last part matters: using an RV as a permanent residence appears to be off the table under the ordinance as written. Manufactured homes are treated differently, they must meet National Building Code and state manufactured housing rules and are allowed at a limited density per acreage. A foundation-built tiny home would likely just be treated like any conventional house.

Building permits. Northfield's Building Inspector and Code Enforcement Officer, Guy Boucher, is the person who determines whether your project needs a building permit or Planning Board review. I'd call before you break ground.

Septic. This one is state-run, not town-run. The NH Department of Environmental Services' Subsurface Systems Bureau issues Construction Approval for a septic design, then an Operational Approval after a field inspection. I didn't find anything in Northfield's ordinance addressing composting toilets specifically, so it's not confirmed how the town treats them, but any conventional septic system falls under DES's Env-Wq 1000 rules regardless.

Greywater and rainwater. I couldn't find Northfield-specific rules on either of these in the zoning text, so I'm calling both unclear. That likely means you're relying on the general (and itself somewhat murky) state baseline, and it's worth asking the Land Use Administrator directly before you build a system.

Wells. Well construction is licensed at the state level by the NH Water Well Board. Locally, if you're inside the Groundwater Protection District, the Planning Board can require a geologist or certified soils scientist to review potential impacts to the aquifer, at the applicant's expense, which can affect well siting.

Utilities. No blanket town-wide ban on disconnecting a permanent house from utilities that I could find, but remember septic and well permitting apply either way, and the RV rule above effectively rules out an off-grid camper as a full-time residence.

Bottom line: Northfield isn't hostile to off-grid living, but it's a zoned town with an aquifer to protect, so plan on paperwork.
