Off-Grid Living in Foxborough, Massachusetts

I'll be upfront: Foxborough is a fully zoned New England town, and that shapes everything about going off-grid here. There's no loophole of "unzoned land" to exploit like you might find out west. Here's what I found digging through the town's official sources.

Zoning. The Town of Foxborough, through its Planning Board, enforces a zoning bylaw (Chapter 275) that divides the town into districts, including R-40 (Residential/Agricultural), which is likely your best bet if you want more breathing room for rural-style living. Only one dwelling per lot is allowed unless the bylaw expressly says otherwise. Any land use has to fit within the town's Table of Use Regulations, so raw land isn't just yours to occupy however you like.

Dwellings, tiny homes, RVs. The bylaw requires a building permit for any structure, and I couldn't confirm any tiny-home minimum-size exemption or an allowance for living in an RV long-term. If that's your plan, call the Building Department before you buy land or a rig, don't assume.

Building permits and codes. The Building Commissioner, under the town's Inspectional Services / Building Department, requires a written permit for anything built, altered, or moved. Foxborough enforces the Massachusetts state building, electrical, plumbing, and gas codes on top of local zoning. This is a code-enforced town, full stop.

Septic and composting toilets. Massachusetts' Title 5 (310 CMR 15.000) is the state baseline for on-site sewage, and Foxborough's Board of Health administers it locally, having adopted its own updated regulations in 2024 that can be stricter than the state minimum. Composting toilets and alternative systems still have to run through this process.

Greywater. I didn't find any Foxborough-specific bylaw that loosens the state rule. Greywater is generally treated like sewage under Title 5, needing a permitted absorption system, and I found no local variance path.

Rainwater harvesting. No town bylaw on this either way. Default state baseline applies, so this looks fine but isn't spelled out locally.

Wells. In Massachusetts, well siting and construction permitting is a local Board of Health function, and Foxborough has its own regulations. I couldn't pull the well-specific text directly, so confirm details with the Board of Health.

Off-grid utilities. You can run on solar and be off the electric grid; that's legal under state rules. But you still need a building permit and code-compliant inspections through the Building Department, and likely a Certificate of Occupancy, regardless of how you power the place.

Bottom line: Foxborough isn't hostile to off-grid living, but it's not a permissive frontier either. Everything runs through the Building Department and Board of Health, and R-40 zoning is probably your friendliest starting point. Call ahead before buying land.
