Off-Grid Living in Shirley, Massachusetts

I've been digging into what it would actually take to live off-grid in Shirley, Massachusetts, and the short answer is: Shirley is a fully zoned New England town, so "off-grid" here means "off the utility grid," not "off the rulebook."

Zoning. Shirley has a Protective Zoning Bylaw, administered by the Planning Board and the Zoning Enforcement Officer, that lays out residential, mixed-use, and industrial districts, plus dimensional and use standards. There's even a Great Road-West Mixed-Use District meant to support a small village node, and the town has been amending its zoning to comply with the state's MBTA Communities Act (MGL c. 40A, §3A). Bottom line: you can't just buy raw land and do whatever you want with it. Whatever you're planning has to fit the district it sits in, and I'd confirm the specific district rules with the Planning Board before you commit to anything.

Dwellings, tiny homes, RVs. I could not find Shirley-specific language on tiny homes or living in an RV full time. That doesn't mean it's fine, it means it isn't spelled out in what I found. The Zoning Bylaw governs dwelling definitions and lot standards generally, so I'd call the Zoning Enforcement Officer directly and ask about minimum size and RV occupancy before you buy or move a structure in.

Building permits. Inspection Services in Shirley issues building permits and enforces the Massachusetts State Building Code (780 CMR), which is a statewide code applied locally. This covers 1- and 2-family dwellings, electrical, gas, mechanical, and plumbing work. Even a small off-grid cabin build is going to run through this office.

Septic and composting toilets. The Shirley Board of Health, working with the Nashoba Associated Boards of Health, enforces the statewide Title 5 septic code (310 CMR 15.000) locally. That covers conventional septic and, by extension, composting toilet setups, since Title 5 is the framework the state uses statewide. There's no local carve-out I found that makes this easier.

Greywater. No town-specific greywater bylaw turned up in my research. That means the state's Title 5 baseline is what governs, enforced locally by the Board of Health/NABOH. Nothing suggests Shirley has loosened the state rule.

Rainwater harvesting. I didn't find a Shirley bylaw addressing this either way. Massachusetts generally allows outdoor rainwater collection while regulating indoor plumbing use more tightly, so absent local rule, that state default is your best guide, but I'd double check with Inspection Services if you're piping it into a house.

Wells. Private wells appear to be permitted, with the Board of Health (again working with NABOH) handling health-related oversight tied to septic and sanitation. I didn't find a standalone well bylaw, so ask the Board of Health directly about siting and testing requirements.

Utility disconnection. Going off-grid electrically isn't banned, but whatever you install, solar, generator, alternative plumbing, still needs to go through Inspection Services' permit and inspection process under the state building, electrical, and plumbing codes.

Nothing here replaces a phone call to Shirley's own offices, especially since bylaws get amended at Town Meeting.
