Off-Grid Living in Newbury, New Hampshire

I've been digging into what off-grid living actually looks like in Newbury, New Hampshire, and the short version is: this is a zoned town with real rules, not a wide-open frontier. Here's what I found, organized by what you'd actually need to deal with.

Zoning. Newbury has a full Zoning Ordinance administered by its Planning Board and Zoning Board of Adjustment, most recently revised in 2026, plus Subdivision Control Regulations that follow the state enabling law (RSA 674:35-42). Lots have to meet dimensional standards, including a "Form Factor" test near roads (lots with more than 300 feet of frontage or over ten acres are exempt from that particular test), and every lot must front on a Class V or better highway or an approved subdivision street. This is town-level regulation, not something the state hands down directly, so any raw-land plans need to go through Newbury's own ordinance.

Dwellings, tiny homes, RVs. I couldn't find a specific Newbury provision addressing tiny houses on wheels or RVs used as residences. The general Building Regulations and Zoning Ordinance talk about "dwellings" and structures broadly, but the gap here is real, so call the Code Enforcement Officer before you plan around a non-traditional dwelling.

Building permits. The town, not the state, requires a Building Permit issued by the Selectboard or Code Enforcement Officer for dwellings, commercial buildings, and other defined structures. Once issued, work must start within six months and the exterior must be finished within two years. Simple repair or restoration without structural changes is exempt. The Code Enforcement Officer fills the RSA 673:1,V building-inspector role for the town.

Septic and composting toilets. This one is layered. New Hampshire's DES Subsurface Systems Bureau has to approve septic installation, replacement, or expansion statewide, and the town can layer on its own cooperation requirements under RSA 485-A. Any structure hooked to a water supply must also connect to an approved wastewater system, whether that's sewer or an individual septic system. I found no Newbury-specific composting toilet ordinance, so that likely falls back to state DES rules; confirm before installing one instead of a septic system.

Greywater and rainwater. I didn't find a Newbury or state rule specifically addressing residential greywater reuse, so treat this as unsettled and ask the town or DES directly. Rainwater harvesting looks fine; I found no restriction, though anything near a lake or pond falls under Newbury's Shoreland Overlay District, tied to the state's Shoreland Water Quality Protection Act.

Wells. Well construction itself is licensed at the state level through the NH Water Well Board. Newbury's own subdivision rules require that lots be sized to safely accommodate on-site sanitary facilities, which indirectly affects how small a lot can be if you're relying on a private well and septic.

Utilities. There's no outright ban on disconnecting from electric or water utilities that I found. The trigger is plumbing: if a structure has a water hookup, it must have DES-approved wastewater disposal. The Planning Board also retains authority to restrict building, sewer, or water permits under certain subdivision covenant circumstances.

Bottom line: Newbury allows a lot of self-reliant living, but it's inside a real zoning and permitting framework, and several details (tiny homes, greywater) just aren't spelled out anywhere I could find, so a phone call to the town office saves guesswork.
