Off-Grid Living in Lempster, New Hampshire

Lempster, New Hampshire is a small Sullivan County town, and one thing that jumps out right away in my research: it appears to be unzoned. The town's own published list of ordinances, regulations, and policies covers things like cemetery rules, dog control, excavation, highway access, the Long Pond beach, parking, snow removal, and street naming, but there's no zoning ordinance, no zoning map, and no Zoning Board of Adjustment listed anywhere on the town's site. That's a real distinction from most New Hampshire towns, which regulate land use through a zoning ordinance adopted under state enabling law. In Lempster, that layer just doesn't seem to exist.

What that means practically: there's no zoning-based restriction on where you can put a dwelling on raw land, no minimum lot size tied to a zoning district, and no permitted-use table to check for tiny homes or ADUs. But "unzoned" doesn't mean "unregulated." The town still requires a building permit for most construction and repairs above a fairly low value threshold, and that permit application asks for plans showing the location of both the building and the septic system. So the building inspector's office (currently Bob Porter, who also serves as the town's health officer) is your practical gatekeeper even without zoning.

Septic is where state authority kicks in hard. Design and approval of septic systems, including composting or alternative systems, is handled by NH DES's Subsurface Systems Bureau at the state level, not by a Lempster ordinance. The town's own building permit process just requires septic location to be shown on your plans, so you're dealing with two authorities: town for the building permit, state for septic approval.

For greywater and rainwater harvesting, I could not find any Lempster-specific rule at all, and my notes don't establish a clear state baseline either. If you're planning a greywater or rainwater system, this is a "confirm before you build" situation, ask the building inspector directly since silence in the ordinance list doesn't guarantee no oversight.

Private wells fall under the state's Water Well Board (RSA 482-B), and I found no town-level supplement to that. Same story with utility hookups, there's no ordinance I found requiring you to connect to water or sewer, so disconnected living seems permissible as long as your septic and building permit boxes are checked.

Bottom line: Lempster's lack of zoning gives you more flexibility than a typical town, but the building permit and state septic rules are still very real, and any grey areas (RVs as dwellings, greywater, tiny homes) deserve a direct call to the building inspector's office before you commit to anything.
