Off-Grid Living in Hatfield, Massachusetts

I've been digging into what off-grid living actually looks like in Hatfield, Massachusetts, and I want to be upfront: this is a small town with real zoning, not a blank slate, and a lot of the finer details on off-grid-specific living just aren't spelled out in public documents I could find. Here's what I know and what's still murky.

Zoning. Hatfield is a zoned town, run under its own Zoning By-laws and map, administered by the town's Planning Board and enforced by the Building Commissioner. On top of the regular districts, there's a Water Supply Protection District overlay covering land in aquifer recharge areas and around the town's reservoirs, and that overlay adds extra rules on top of whatever the underlying district allows. If you're eyeing raw land, especially anywhere near water sources, check whether it falls in that overlay before you plan anything.

Dwellings, tiny homes, RVs. I didn't find Hatfield-specific rules on tiny homes or living in an RV full time. The bylaw does address Accessory Dwelling Units under the 2024 Massachusetts ADU law, which allows ADUs by-right in residential districts if they meet certain standards, but that's a state-driven baseline, not something Hatfield invented. For anything outside a conventional stick-built home, I'd call the Building Commissioner's office directly.

Building permits and code. This runs through the Building Commissioner, who's licensed by the Commonwealth and enforces the state building code locally, and who also acts as the Zoning Enforcement Officer. Any construction gets reviewed by this office.

Septic and composting toilets. Massachusetts' Title 5 wastewater regulation (a state DEP rule) is enforced locally by Hatfield's Board of Health, an elected three-member board that handles all septic inspections and perc tests by appointment. Composting toilets would still need to satisfy Title 5 or an approved alternative, so that's a Board of Health conversation.

Greywater. No Hatfield-specific greywater bylaw turned up in my research. Since the Board of Health administers Title 5, greywater is treated as regulated wastewater under the state baseline, and I couldn't confirm whether the town offers any local variance for garden reuse or similar setups.

Rainwater harvesting. Nothing Hatfield-specific here either. The general Massachusetts baseline (outdoor use is fine, indoor use needs more care) would apply, but confirm with the town if you're planning anything substantial.

Wells. Private wells fall under Board of Health oversight, and if you're in the Water Supply Protection District's Zone II (the area feeding a well's aquifer), there are added siting considerations layered on top of standard zoning.

Utilities. I found no Hatfield bylaw that explicitly bans or blesses disconnecting from the grid. Realistically, though, any structure still has to meet the state building and electrical code, so the Building Commissioner's office is your enforcement contact regardless of hookups.

Bottom line: Hatfield isn't hostile to off-grid living on paper, but it isn't spelling it out either. A lot of this comes down to calling the town directly before you buy or build.
