Off-Grid Living in Dighton, Massachusetts

If you're eyeing a piece of land in Dighton, Massachusetts for an off-grid setup, here's what I found digging through the town's official records.

Zoning is real here. Dighton is not one of those unzoned rural towns you sometimes find out west. The town has a full zoning bylaw, administered by the Planning Board and enforced by the Building Commissioner acting as Zoning Enforcement Officer. That means whatever you want to do with land, from where you put a structure to what counts as an accessory building, runs through district-based rules on the town's official zoning map. I'd start with the Table of Dimensional Regulations on the town website before you buy anything.

Tiny homes and RVs as full-time dwellings are a genuine grey area. I could not locate specific bylaw language addressing minimum dwelling size or living in an RV as a residence. The bylaw does regulate accessory structures (small detached buildings under a certain footprint have their own setback rules), but I'd call the Building Commissioner's office directly before assuming a tiny home or RV is a legal permanent dwelling on your lot.

Building permits follow the state code. Dighton's Building and Inspections Department applies the Massachusetts State Building Code (780 CMR, 9th Edition), and you'll need a certificate of occupancy from the Building Commissioner before anyone can legally live in a new structure.

Septic is state law, locally enforced. Massachusetts Title 5 (310 CMR 15.000) governs septic systems statewide, and Dighton's Board of Health handles the local permit process, including requiring a locally licensed installer. There's no shortcut around Title 5 for a composting toilet setup either, if it involves any wastewater discharge; the town's own Homeowner's Guide to Title 5 is worth reading start to finish.

Greywater and rainwater harvesting have no Dighton-specific rules that I could find. That means the state Title 5 baseline (treatment through soil absorption) is what applies to greywater by default, and rainwater collection doesn't appear to have any town bylaw addressing it one way or the other. Ask the Board of Health if you're planning something beyond simple rain barrels.

Wells are permitted but locally regulated through the Board of Health, following the statewide pattern of local health department oversight on well siting and construction. I didn't find Dighton-specific well text, so confirm particulars with them.

Going off-grid on utilities has some legal protection for solar, at least. A 2022 Town Meeting bylaw was reviewed under state law (G.L. c. 40A §3), which bars towns from unreasonably restricting solar energy systems except for real health/safety reasons. That said, any off-grid electrical work still needs to meet the state building code and go through licensed-electrician permitting with the Building Department. This isn't a jurisdiction where you can just wire your own cabin and call it done.

Bottom line: Dighton is a zoned New England town where the state building and health codes do most of the heavy lifting, with the Board of Health and Building Commissioner as your two main points of contact. Nothing here suggests off-grid living is banned, but nothing suggests it's a free-for-all either. Call before you build.
