Off-Grid Living in Mount Washington, Massachusetts

Mount Washington is a small hill town in the Berkshires, and like most Massachusetts towns it IS zoned, so the idea of just buying raw land and doing whatever you want doesn't apply here. I want to be upfront that this research pass didn't turn up every section-level detail, and I'll flag exactly where you need to call the town yourself.

Zoning is active and administered by the Planning Board, which handles special permits and site plan review, per the town's own bylaw. The Zoning Board of Appeals handles variances and appeals, but it does not issue special permits itself, that's the Planning Board's job. If you're eyeing a parcel, start with the Planning Board.

Dwellings, tiny homes, and RVs: I could not confirm a specific bylaw provision on minimum dwelling size, RV living, or tiny homes in the pages I reviewed. The general zoning bylaw likely addresses this, but I did not get the section text. Ask the Planning Board or pull the full bylaw from the town's Bylaws page before you assume anything is or isn't allowed.

Building permits and codes: The Building Inspector reviews alterations against the Massachusetts Building Code (a statewide code) and the town's own Zoning Bylaw. Any structure you build will need to go through this local office.

Septic and composting toilets: This is state-driven with local enforcement. Massachusetts Title 5 (310 CMR 15.000) sets the baseline septic standard statewide, and Mount Washington's Board of Health enforces it locally under 105 CMR 410 (the state sanitary code), including issuing correction orders when systems are out of compliance. Composting toilets as a sole system would still need to satisfy this framework, so talk to the Board of Health directly.

Greywater: No town-specific policy turned up. By default, Massachusetts Title 5 treats greywater as wastewater needing an approved soil absorption system, so absent local carve-outs, plan around that state baseline.

Rainwater harvesting: No town-specific bylaw or Board of Health guidance found. Nothing suggests it's prohibited, but nothing confirms special permitting either.

Wells: The Board of Health is the local authority here, though I didn't find a dedicated town well bylaw. Water resource matters are listed among the town's active committee functions, so the Board of Health is your first call.

Utility disconnection: No Mount Washington bylaw specifically addresses living off-grid or disconnected from utilities. The state baseline (permitted, with electrical work needing to meet 780 CMR, the state building code's electrical provisions) would apply unless the town says otherwise.

Bottom line: Mount Washington isn't hostile to off-grid living, but it's also not a rural-Wyoming free-for-all. Zoning, building, and septic all run through named local offices layered on top of state rules, and several dimensions here just weren't confirmable from the documents I found. A phone call to Town Hall will save you guesswork.
