Off-Grid Living in Blackstone, Massachusetts

Blackstone, Massachusetts is a fully zoned town, and that's the first thing to understand if you're dreaming of an off-grid setup here. The Zoning Bylaw is Chapter 123 of the Town Code, adopted under the state's Chapter 40A enabling law, and it's enforced locally by a Zoning Agent appointed by the Selectmen. So any plan for raw land, a tiny house, or a fully self-sufficient homestead has to run through the town's Use Schedule and district map, not just state rules.

On zoning and land use, Blackstone has carved out overlay districts, including a Flood Hazard District, a Groundwater Protection District, and a Village Overlay District, layered on top of its base zoning districts. Where your parcel sits on that map matters a lot, especially the Groundwater Protection overlay, which can add scrutiny to septic and well siting. I'd call this "restricted" rather than "permitted," because it's use-schedule driven, not a free-for-all.

I could not find any Blackstone-specific bylaw addressing tiny homes or RV dwelling directly. That means you're likely working from the general dimensional and use requirements of Chapter 123, plus the state building code baseline (which includes the Appendix Q tiny-house provisions at the state level, not confirmed whether Blackstone modifies these). Building permits themselves go through the town's Building Department / Inspectional Services, referenced as a separate chapter (57) from zoning.

Septic is where the state's Title 5 program (310 CMR 15.00) does the heavy lifting, but it's the Blackstone Board of Health that actually administers it locally, including for any new construction, and you'll need permits from both the Board of Health and the Building Department. Towns are allowed to be stricter than Title 5 if adopted properly, so ask the Board of Health directly whether Blackstone has added anything. Composting toilets aren't addressed in a town-specific bylaw as far as I found, so state Title 5 rules would govern.

Greywater and rainwater harvesting are both areas where I found no Blackstone-specific bylaw. Greywater defaults to the state Title 5 baseline, which generally treats it as wastewater. Rainwater catchment isn't prohibited outright; the town does have a stormwater management bylaw, but that's about site drainage and resource-area protection, not personal rain barrels or cisterns.

Private wells are permitted, with the Board of Health handling well permitting, but again the Groundwater Protection District overlay may affect siting if your land falls in a mapped aquifer or recharge area.

Living off-grid, unhooked from municipal utilities, isn't specifically banned by any Blackstone bylaw I found. But whatever you build still needs to satisfy the state building code and pass through zoning and building enforcement like anything else in town.

Bottom line: Massachusetts sets the statewide floor (Title 5, state building code), and Blackstone's Board of Health, Building Department, and Zoning Agent decide how it plays out on your specific parcel. Call before you commit to a plan.
