Off-Grid Living in Bolton, Massachusetts

I've been digging through Bolton, Massachusetts's actual bylaws and Board of Health regulations to figure out what off-grid living really looks like here, and the short version is: Bolton is a fully zoned town, and it layers its own local rules on top of the Massachusetts state code at nearly every turn. This isn't unzoned rural land where you can just set up and live quietly.

Zoning. Bolton adopted its Zoning Bylaw (Chapter 250) at Town Meeting back in 2012, under the state's Chapter 40A zoning enabling law. The town has residential, agricultural, and overlay districts, including a Farmland Restriction (FR) district that's quite tight, only a small percentage of that land can hold barns or ag buildings, and only farming uses are allowed. If you want a smaller, unconventional lot, the Planning Board can grant a Special Permit for a "backland lot" with reduced frontage but more required acreage. Bottom line: what you can do with raw land in Bolton depends heavily on which district it sits in, so check with the Planning Board before assuming anything.

Dwellings, tiny homes, and RVs. Bolton's bylaw formally defines Accessory Dwelling Units and larger "Secondary Units," all of which need building and occupancy permits from the Building Inspector and have to meet dimensional rules. I did not find a Bolton bylaw that lets you live in an RV or tiny home as a primary residence long-term; Massachusetts' state Appendix Q covers tiny homes generally, but Bolton hasn't been confirmed to have loosened its own minimum size standards.

Building permits. The Building Department, currently under Building Inspector Michael Sauvageau, enforces the state building code locally. Even driveways need a joint permit from the Planning Board and Building Inspector in residential districts, so expect permitting to touch more than just the house itself.

Septic and greywater. Bolton's Board of Health enforces Title 5 of the state Environmental Code (310 CMR 15.00) for all sewage disposal, and it has adopted its own local sewage disposal regulation on top of that baseline. Composting toilets and greywater reuse aren't addressed separately in anything I found at the town level, so they fall back to the state Title 5 framework, which treats greywater as wastewater needing an approved system.

Rainwater. No town-specific rule turned up here. It appears to follow the general Massachusetts baseline: outdoor non-potable collection is generally fine, indoor potable use runs into plumbing code questions.

Wells. Bolton's Board of Health maintains its own Well Regulations, layered on top of state DEP minimums, so well siting and construction here isn't just a state matter, it's a local Board of Health matter too.

Utility disconnection. I didn't find any Bolton bylaw banning full off-grid utility disconnection. The zoning bylaw does have a solar overlay district, but it's aimed at commercial-scale solar installations, not residential systems. A home solar setup would still go through the Building Inspector's normal permitting.

Given how much of this is locally layered, your best move is calling the specific offices below before you buy land or start building.
