Off-Grid Living in Danvers, Massachusetts

I've been digging into what off-grid living actually looks like in Danvers, Massachusetts, and the short version is: this is a fully zoned New England town, not open rural land, so anything you want to build or run off-grid has to work within the Danvers Zoning Bylaw and the Massachusetts State Building Code on top of it.

Zoning. Danvers is zoned town-wide by the Planning Board and Building Commissioner (who also acts as Zoning Administrator), using a mix of traditional districts and newer Character-Based Zoning Districts. There's also a Groundwater Protection District overlay covering aquifers and recharge areas, which matters a lot if you're eyeing raw land for a well or septic system, since it can add siting restrictions. Any raw parcel you're considering should be checked against both the base zoning district and this overlay before you assume you can build or drill.

Dwellings, tiny homes, RVs. I could not find a Danvers-specific rule spelling out minimum dwelling size or whether an RV can be lived in long-term. What I did confirm is that any new structure needs a Certificate of Occupancy, and if it doesn't fit an allowed building type under the Planning Board's regulations, it has to go through Special Permit review. Call the Planning Board directly before you commit to a tiny home or RV as a permanent residence.

Building permits. All construction runs through Inspectional Services under the statewide 780 CMR building code. That's a state-level code enforced locally, so Danvers doesn't have its own separate building standard, but the town's Building Commissioner issues the permits and signs off on occupancy.

Septic and greywater. Massachusetts' Title 5 (310 CMR 15.00), a state regulation from MassDEP, governs septic design and installation everywhere in the Commonwealth, and Danvers' Board of Health enforces it locally with its own supplementary regulations. I did not find any town-specific greywater allowance, so greywater falls under the same Title 5 wastewater framework, meaning it generally needs to run through an approved system rather than informal reuse.

Rainwater. No Danvers bylaw on rainwater harvesting turned up in my research either way, so this appears to default to the general state baseline, which doesn't prohibit it outright. Worth confirming with the town if you're planning anything beyond a basic barrel.

Wells. Private wells are permitted, but the Board of Health inspects and licenses them, and again, the Groundwater Protection District overlay can restrict siting near protected aquifers.

Utilities. There's no bylaw banning off-grid utility living outright, but whatever you build still has to clear 780 CMR building code review and get a Certificate of Occupancy, so "off-grid" doesn't mean "off the books" here.

Bottom line: Danvers allows a lot of this in principle, but everything routes through town boards, so plan on phone calls before dirt moves.
