Off-Grid Living in Brookline, New Hampshire

I've been digging through Brookline, New Hampshire's zoning ordinance and building department pages, and I want to be upfront: Brookline is a zoned town, not one of those unzoned rural spots people dream about for off-grid freedom. That changes the whole picture.

Zoning. The Town of Brookline, under authority granted by the state (RSA 674:16), maintains its own Zoning and Land Use Ordinance, administered by the Planning Board. There are three base districts (Industrial-Commercial, Residential-Agricultural, Downtown Village) plus overlay Wetlands Conservation and Aquifer Protection Districts. Lots need real frontage and setbacks, so you can't just park on raw land and start living there without going through the town's permitting process.

Dwellings, tiny homes, RVs. Here's where things get tough for off-gridders: Brookline's ordinance sets a hard minimum floor area for any new dwelling, and manufactured housing has its own (smaller but still real) minimum. That effectively rules out most tiny homes and RVs as year-round residences. The ordinance does define a "Camp," but that's explicitly seasonal, not a full-time residence workaround.

Building permits. The Building Department requires drawings, a site plan showing septic, driveway, and drainage, and state-approved septic plans before any permit is issued. Only very small accessory buildings (100 square feet or less) skip the permit, and even those still have to meet setback rules. Any licensed trade work (electrical, plumbing, gas) needs an NH-licensed master.

Septic. This is a real gatekeeper. Brookline won't issue a building permit without an approved State of New Hampshire septic design first, which ties you into NH DES's Subsurface Systems Bureau rules. I did not find a town-specific composting toilet ordinance, so that would fall back to the state's general wastewater rules, worth confirming directly with DES.

Greywater and rainwater. I couldn't find any Brookline-specific rules on either one. That doesn't mean "anything goes," it means the town hasn't addressed it separately, so I'd call this unconfirmed and worth asking the Building Department about directly.

Wells. No town-specific well ordinance turned up in my research. The zoning ordinance does tie water supply into its "buildable area" definition, but for actual well construction standards you're looking at the state's Water Well Board rules, not a Brookline ordinance.

Utilities / living disconnected. Because a state-approved septic plan and a minimum dwelling size are both preconditions for a Brookline building permit, going fully off the grid unpermitted, or building small and disconnected, is not something the town's process straightforwardly accommodates. Any new permanent structure has to go through full site-plan review.

Bottom line: Brookline is a workable place to build conventionally with septic and standard-size construction, but it is not friendly to minimalist or fully disconnected off-grid setups. I'd call the Building Department early, before buying land, to confirm what's actually possible on a specific parcel.
