Off-Grid Living in Pembroke, Massachusetts

I dug into Pembroke, Massachusetts, for anyone thinking about living off-grid there, and the short version is: this is a conventionally zoned New England town, not a rural free-for-all, so plan on working with several town offices plus the state.

Zoning. Pembroke has standard Euclidean zoning under its town bylaw, with Residence, Residential-Commercial, Business, and Industrial districts, plus overlay districts for water resources and floodplains. There's no separate category for "off-grid" land use; whatever you want to do has to fit the use table and dimensional rules (lot size, frontage, etc.) for whichever district your parcel sits in. I'd start by asking the Planning Board which district your land is in before assuming anything is allowed.

Dwellings, tiny homes, RVs. The bylaw has a dedicated "Trailers" section governing trailer and camper occupancy, separate from how it treats unregistered recreational vehicles for junk-vehicle purposes. Don't confuse the two: being exempt from junk-vehicle rules is not the same as being cleared to live in an RV full-time. If you're set on a tiny home or trailer as a primary residence, that's a conversation for the Building Inspector and Planning Board, not something to assume is fine.

Building permits. The town's Building Inspector issues permits and signs off on occupancy, with Fire Department involvement too. One useful, confirmed detail: Pembroke recently updated its bylaw to allow accessory dwelling units (ADUs) by right, per the state's ADU law, capped at half the size of the existing house or 900 square feet, whichever is smaller, and only a building permit is needed (no special permit). That could be a real option for smaller off-grid-style living on an already-developed lot.

Septic and composting toilets. This is where Pembroke gets notably stricter than the state. The Board of Health enforces the state's Title 5 code plus town-specific amendments. A cesspool is now an automatic fail whenever a property changes hands. Pembroke also uses a higher design-flow number (150 gallons per bedroom per day) than the state's 110 for some upgrades, tightening for smaller lots or waterfront property. Septic installers must hold a town license on top of any state credential.

Greywater. No standalone Pembroke greywater ordinance turned up; it's regulated as wastewater under Title 5, and the town's own rules reference setbacks for greywater disposal facilities relative to wells.

Rainwater harvesting. I found no Pembroke-specific rule on this either way, so treat it as governed by whatever the state baseline is, and confirm with the Board of Health if you're planning something significant.

Wells. The Board of Health regulates well placement, including a required separation from leaching fields, privies, and greywater disposal.

Off-grid utilities. No bylaw bans disconnecting from the grid. Solar has its own dedicated bylaw section. Occupancy sign-off from the Building Inspector still applies regardless of whether you're grid-tied.

Bottom line: Pembroke is workable for off-grid ambitions but not hands-off, call the Planning Board and Building Inspector early.
