Off-Grid Living in Carver, Massachusetts

I've been digging into what it actually takes to live off-grid in Carver, Massachusetts, and the short version is: this is a zoned town with real oversight, so "off-grid" here means "self-sufficient utilities on a property that still meets state and local permitting rules," not "do whatever you want on your land."

Zoning. Carver's zoning bylaw is codified as Chapter 290 of the Town of Carver Code, administered by the Planning Board and enforced by the Building Inspector. It applies townwide, even to land divisions that don't require formal subdivision approval, and the bylaw includes growth-management provisions capping how many building permits can be issued in a year on larger subdivided tracts. Bottom line: you can't just buy raw land and occupy it without going through the town's permitting process.

Dwellings, tiny homes, RVs. Any dwelling has to meet the Massachusetts State Building Code, which the bylaw explicitly references. I did not find Carver-specific language allowing RVs or tiny homes as permanent residences, so I'd treat RVs as temporary/accessory structures unless the Building Inspector tells you otherwise. Whether the state's Appendix Q (small home provisions) has been locally adopted with tweaks isn't confirmed, so ask the Building Department directly.

Building permits. The Building Inspector's office requires a permit application and a to-scale plot plan, and by state code has a defined review window. You'll need a Certificate of Occupancy once final inspection passes. This process is the gatekeeper for pretty much every off-grid structure you'd build.

Septic and composting toilets. Massachusetts regulates septic under Title 5 (310 CMR 15.000), a state program administered by MassDEP but enforced locally by Carver's Board of Health. I didn't find a town-specific composting toilet allowance, so the Title 5 baseline governs, and the local Board of Health can impose stricter conditions than the state minimum.

Greywater. No Carver-specific greywater bylaw turned up; this falls under the same statewide Title 5 framework, enforced locally.

Rainwater harvesting. I couldn't confirm any Carver-specific rule here at all, no town bylaw or Board of Health regulation was found. The general assumption in Massachusetts is that outdoor rainwater use is fine while indoor use runs into plumbing and Title 5 restrictions, but confirm with the Board of Health before relying on it.

Wells. Well siting and approval run through the local Board of Health, which is standard practice statewide. I didn't find a standalone Carver well bylaw text, so call the Board of Health directly for specifics.

Utilities. There's no bylaw banning off-grid living outright, but any structure still needs a Building Permit and Certificate of Occupancy, and electrical/solar work needs licensed electricians under state code.

Nothing here is a substitute for a conversation with Carver's Planning Board, Building Department, and Board of Health, since local interpretation matters a lot in Massachusetts zoning.
