Off-Grid Living in Walpole, New Hampshire

I've been digging through Walpole, New Hampshire's town documents and the relevant state rules for anyone thinking about buying land here and living off-grid. Here's where things stand, and where I still have questions the town would need to answer directly.

Zoning. Walpole is a zoned town. It has an adopted Zoning Ordinance (available on walpolenh.us) that works alongside state enabling law, RSA 674:33. The town splits into districts, Residential A, Residential B, Rural/Agricultural, and Commercial, each with its own minimum lot size and use rules. One quirk worth knowing: the North Walpole Village Precinct is specifically excluded from the Zoning Ordinance, so that pocket of town may not follow the same rules as the rest of Walpole. Everywhere else, the Planning Board handles subdivisions and zoning amendments, and Site Plan Review Regulations apply to new development.

Dwellings, tiny homes, RVs. This is where I'd tell you to slow down. The Zoning Board of Adjustment has to approve any temporary use of a trailer or mobile home under the zoning ordinance, meaning you can't just park one and live in it by right. Detached accessory dwelling units are recognized and reviewed by the town, so a small secondary dwelling might be a legitimate path, but I found no dedicated provision for a tiny house on wheels as a permanent residence. If that's your plan, call the ZBA before you buy anything.

Building permits. The Selectboard Office issues building permits, and Walpole requires them for a lot more than you might expect, solar arrays, demolition, fences, gutters, interior renovations, and any new structure over 100 square feet including sheds and decks. Commercial expansions need Planning Board sign-off first. Energy code questions get referred to the state Public Utilities Commission.

Septic. This is state territory. NH DES's Subsurface Systems Bureau must approve any septic system before it's installed, replaced, or expanded, and any structure hooked to a water supply must have an approved wastewater system. Homeowners can sometimes design their own system for their own home under DES rules, though a licensed designer is otherwise required. I didn't find a Walpole-specific composting toilet ordinance, so check with the town and DES directly on that.

Greywater and rainwater. Neither has a Walpole-specific ordinance that I could find. Greywater reuse rules are genuinely unclear at the state level too. Rainwater harvesting for non-potable indoor use appears fine under the state's adopted codes, with no added town restriction found.

Wells. Private wells fall under the state Water Well Board (RSA 482-B); I found no added Walpole well ordinance. The town's Water and Sewer Department only matters if you're connecting to municipal service.

Full off-grid living. No well and no septic at all isn't something I found addressed head-on in town documents. The clearest rule is the state one: if you have water supply, you need an approved wastewater system. Beyond that, confirm directly with the Selectboard Office.
