Off-Grid Living in Bennington, New Hampshire

If you're eyeing raw land in Bennington, New Hampshire for an off-grid setup, here's what I found digging through the town's own documents and state resources.

Zoning is real here. Bennington is a zoned town, with districts including Rural/Agricultural, Village, Commercial/Recreational, and Industrial, plus a Water Resource Protection overlay covering most of the Village District and part of Rural/Agricultural. That means what you can do with raw land, and what you can build, depends heavily on which district your parcel sits in. The Zoning Ordinance also governs subdivisions and site plans, so if you're buying acreage to split or develop, the Planning Board's Subdivision and Site Plan Review Regulations come into play too.

Dwellings are where things get murky. The Master Plan and Ordinance set dwelling types and lot requirements per district, and the town allows one accessory dwelling unit per primary dwelling in the Village and Rural/Agricultural districts, but only with a special exception from the Zoning Board of Adjustment. I did not find a clear answer on tiny homes on wheels or RVs as permanent residences in the sections I reviewed. This is a call-the-Zoning-Administrator question, not a guess-and-hope one.

Building permits are required, full stop. Bennington's Code Enforcement Officer enforces the New Hampshire State Building Code (which bundles the IBC, IRC, plumbing, mechanical, energy, electrical, and life safety codes). Your application gets checked against building, zoning, site plan, and subdivision rules together.

Septic runs through the state. Any new, replaced, or expanded septic system needs written approval from NH DES's Subsurface Systems Bureau before installation, per state law (RSA 485-A), and Bennington's building permit process confirms septic compliance before final sign-off. I couldn't confirm a specific composting toilet policy at the town level, so that's another one for the Building Inspector.

Greywater and rainwater harvesting don't have town-specific rules I could locate. That leaves you leaning on the state baseline and whatever the Building Inspector says applies through the plumbing code.

Wells are state-licensed through the NH Water Well Board, no unique Bennington wrinkle found beyond the water resource protection overlay zones. But here's the catch for full off-grid living: state rule says any structure connected to a water supply must also have an approved wastewater disposal system. That functionally limits how "disconnected" your water and waste setup can be, even if nobody's forcing you onto municipal electric.

Bottom line on utilities: no explicit town ban on going off the electric grid, but water and wastewater are linked by state rule in a way that limits informal setups.

Given the real gaps here, my strong recommendation is to call before you buy, not after.
