Off-Grid Living in Haverhill, New Hampshire

I've spent a while digging through Haverhill, New Hampshire's town documents, and the honest headline is this: Haverhill doesn't have one townwide zoning code. It's a patchwork. Only two precincts, Haverhill Corner and Mountain Lakes, have adopted zoning ordinances (Haverhill Corner's dates to a 2010 revision, Mountain Lakes' from 2011). If your land is in North Haverhill, Woodsville, Pike, East Haverhill, or another unzoned part of town, there's no use-based zoning code telling you what you can and can't do with raw land, just subdivision regulations and other townwide ordinances (building/fire code, flood, driveway, Class VI road rules). Don't assume "unzoned" though, confirm your parcel's status with the Planning Board before you buy or build anything.

On dwellings, tiny homes, and RVs, I couldn't find a Haverhill-specific ordinance addressing these directly. Absent a town rule, state RV/campground regulations would likely fill the gap, but this is genuinely unconfirmed at the town level, so call the Planning Board or Building Inspector before you plant a tiny house or camp long-term.

Building permits, on the other hand, are solidly townwide. Haverhill runs its own permit process through a Town Inspector under a 2010 Building Permit and Fire Code Ordinance, and I've seen the fee schedule and permit application. There are life-safety requirements baked in, hard-wired smoke detection per NFPA codes, and oil-fired furnaces installed per NH RSA 153:5. There's also a construction timeline: you need an appreciable start (foundation done) within a set window of permit issuance, with a possible extension, and completion required within a set outer limit, so ask the Building Inspector about current deadlines rather than assume.

Septic is a state show, not a town one. NHDES's Subsurface Systems Bureau regulates septic systems statewide, and any structure hooked to a water supply must also connect to a wastewater system (sewer or individual septic). Some NH towns are "Prior Approval Towns" requiring town sign-off on top of state approval, I don't have confirmation either way on whether Haverhill is one, so ask NHDES or the town directly. Composting toilets aren't separately addressed in what I found.

Greywater reuse and rainwater harvesting both come up empty for Haverhill-specific rules. State plumbing code provisions would apply by default through the town's adoption of state building code, but there's no local ordinance I could confirm.

Private wells are licensed at the state level, and NHDES documents mention Haverhill properties may use either an on-site well or a municipal/community water connection, but no separate town well ordinance turned up.

Bottom line on "living disconnected": the state's septic-to-water-supply linkage means you can't just skip wastewater infrastructure if you have a water supply. Beyond that, I found no Haverhill ordinance forcing utility hookups.
