Off-Grid Living in Langdon, New Hampshire

Langdon, New Hampshire is a small town, but don't let that fool you into thinking it's unzoned wild country. I've dug through what's publicly available, and here's where things stand as of my research.
Zoning. Langdon IS zoned, under its Zoning Ordinance of 1973, administered locally with a Zoning Board of Adjustment that hears variances and special exceptions per the state enabling law, RSA 674:16. That ordinance also has a Floodplain Management overlay tied into it. I could not pull the specific district rules or lot-size minimums from the excerpt I found, so if you're eyeing a parcel, call the town and ask what district it sits in before you assume anything about what you can do with raw land.
Dwellings, tiny homes, RVs. This one's genuinely not confirmed. The town does have a building permit form specifically for "Dwellings, Additions, Accessory Buildings, & Manufactured Buildings," which tells me manufactured housing is at least on the town's radar, but I couldn't find explicit language on tiny homes or RV living. Ask the Building Inspector directly.
Building permits. Confirmed: Langdon requires building permits, foundation permits, and Certificates of Occupancy, administered by the town's Building Inspector, separate from zoning administration.
Septic and composting toilets. Handled at the state level. All septic systems in New Hampshire, including Langdon, fall under NH DES Subsurface Systems Bureau rules (RSA 485-A and the Env-Wq 1000 rules). I found no Langdon-specific composting toilet ordinance, so that state layer is what governs.
Greywater. Not confirmed. I found no Langdon ordinance addressing greywater reuse, and New Hampshire doesn't appear to have a dedicated statewide residential greywater rule either. This is a genuine gray area, pun intended, worth asking DES and the town both.
Rainwater harvesting. Same story, not confirmed at the town level. There may be provisions folded into the state building/plumbing code that Langdon adopts by reference, but I couldn't verify that from what's published.
Wells. Governed by the state's Water Well Board under RSA 482-B, the same baseline that applies everywhere in New Hampshire. No extra Langdon-specific well restriction turned up in my research.
Utility disconnection. Not confirmed. I didn't find a Langdon health ordinance or subdivision rule requiring hookups to utilities, but the town's Subdivision Regulations and Site Plan Review documents might address this and I couldn't get the full text. Worth a direct call before you commit to living off-grid on a subdivided lot.
Bottom line: Langdon is a zoned town where the state does a lot of the heavy lifting on septic and wells, but several off-grid-relevant questions, tiny homes, greywater, rainwater, and utility disconnection, are simply not spelled out in what I could find. Call before you build.
