Off-Grid Living in South Hampton, New Hampshire
South Hampton, NH is a zoned town with local building and zoning oversight, plus state-level septic (NH DES) and well regulation, but many off-grid specifics like tiny homes, greywater, and utility-disconnection rules aren't published anywhere I could confirm. Call Town Hall directly before relying on assumptions.
Is it legal to live off-grid in South Hampton, New Hampshire?
There is no outright ban on living off-grid in South Hampton, New Hampshire - it is possible, but the local rules are not all documented online. Zoning and land use are set locally and vary by area, putting a cabin, tiny home, or RV on raw land is not clearly documented online, so confirm it locally, and building permits are set locally and vary by area. Plan around septic/wastewater (generally allowed) and disconnecting from utilities (not clearly documented online, so confirm it locally). Because these rules are set locally, confirm the specifics with South Hampton before you buy land or build.

I'll be upfront: South Hampton, New Hampshire is a small town, and its official web presence doesn't have everything I'd want for a full off-grid picture. Here's what I could confirm, and where I hit walls.
Zoning. South Hampton is zoned, not a blank slate. There's an active Zoning Board of Adjustment (meets as needed, third Thursday of the month) and a Planning Board that handles land-use matters. The town's Zoning Ordinance and official map are the final word, but I couldn't pull the actual district names, minimum lot sizes, or use tables from what's published online. If you're eyeing a parcel for off-grid use, don't guess, get the ordinance from Town Hall or the town's zoning page and confirm what your specific parcel allows.
Dwellings, tiny homes, RVs. No South Hampton-specific rule on tiny homes, ADUs, or RV living turned up in my research. New Hampshire generally leaves this to the town, so South Hampton's own ordinance would govern, but I'd call the town office directly since it's not posted.
Building permits. New Hampshire's state building code puts permitting and enforcement in the hands of the municipality. South Hampton's Planning Board and presumably a building inspector handle this locally, but I couldn't find a dedicated building-permit page for the town. Assume you need a permit for any dwelling and confirm the process with Town Hall.
Septic. This one's clearer. New Hampshire's Department of Environmental Services (DES), Subsurface Systems Bureau, approves septic designs statewide under RSA 485-A, and any structure with a water supply and wastewater discharge needs an approved septic system. The applicant has to certify compliance with local requirements too, so the town plays a role, but the state agency issues the actual approval. Composting toilets aren't separately addressed for South Hampton that I could find.
Greywater. No South Hampton or state rule specific to residential greywater reuse turned up. Treat this as an open question and ask DES or the town directly before building a greywater system.
Rainwater harvesting. Nothing in my research suggests South Hampton restricts this beyond the general state plumbing code baseline, so it looks permitted.
Wells. Private wells fall under the statewide NH Water Well Board framework, and I didn't find any extra South Hampton well ordinance layered on top.
Utility disconnection. I didn't find a South Hampton ordinance requiring hookup to water or sewer, and it's a small rural town without municipal systems mentioned in what I found. That suggests off-grid living is plausible here, but it's not explicitly confirmed by an official source, so don't take my word as the last one.
Bottom line: South Hampton has real zoning and building oversight, state agencies handle septic and wells, and several details (tiny homes, greywater, utility rules) just aren't published where I could find them. A phone call or visit to Town Hall will save you guesswork.
