Off-Grid Laws in Vermont

I've spent a good chunk of time digging through Vermont's state statutes and agency pages to figure out what actually governs off-grid living here, and the honest answer is: it's a patchwork. There's no "off-grid permit" you can apply for. Instead, you're dealing with a state environmental permitting layer (mostly water and wastewater) stacked on top of whatever your specific town decides about zoning and building. I'll walk through what I found, but plan on calling your town office too, because that's where a lot of the real answers live.

Zoning and just occupying land. For ordinary raw-land occupancy, zoning is a town-level matter in Vermont, full stop. The state only steps in through Act 250, its land use and development review law, and that's aimed at larger development or subdivision activity, not someone just living on a parcel. The threshold for needing an Act 250 permit is lower (around one acre) in towns without their own zoning and subdivision bylaws, and higher (around ten acres) in towns that have adopted robust bylaws, according to the state's Act 250 program. So the more your town regulates locally, the less Act 250 tends to apply to you directly.

Tiny homes, RVs, and dwelling type. I couldn't find any statewide rule setting minimum square footage or governing whether you can live in an RV or tiny home permanently. This is entirely a town-by-town zoning question. Some Vermont towns are quite permissive, others aren't; you really do need to call the specific town's zoning administrator or planning commission before you buy land or move a structure onto it.

Building codes. Here's a genuinely useful fact: Vermont has no statewide residential building code for owner-occupied single-family homes. The state's Fire and Building Safety Code, run by the Division of Fire Safety, covers commercial buildings, rentals, schools, and multi-family housing, but explicitly not single-family owner-occupied homes. What Vermont does enforce statewide is its Residential Building Energy Standards (RBES), administered by the Department of Public Service, which apply to new homes and to additions, alterations, and repairs on residential buildings up to three stories. So even without a structural code, there's an energy compliance layer you can't skip.

Septic and composting toilets. This is where Vermont gets strict. The Department of Environmental Conservation's Wastewater System and Potable Water Supply Rules require a permit for basically any wastewater disposal method, and that includes composting and incinerating toilets, which are allowed but not permit-free. There's an exemption path for what the state calls a "primitive camp," where you skip the water supply permit and can use a waterless toilet, but the moment you install a soil-based wastewater system, a permit is required.

Greywater. Vermont doesn't have a separate greywater law. Greywater systems get folded into the same Wastewater System and Potable Water Supply Rules as any other non-conventional disposal system, meaning DEC evaluates and permits them case by case rather than under a dedicated statute.

Rainwater harvesting. For outdoor, non-potable uses like irrigation, EPA's summary of Vermont's reuse framework confirms this is a recognized practice. If you want to bring harvested rainwater indoors as your potable water source, though, you're back under DEC's Potable Water Supply Rules.

Wells. Once a well is in and working, Vermont mostly leaves private water sources alone; neither the EPA nor the state actively regulates household well water except at the point of drilling. New groundwater wells for single-family homes must be tested, per state law, and DEC sets construction, siting, and licensing standards for well drillers. So the drilling and testing moment is regulated, ongoing use generally isn't.

Living unconnected from utilities. Nothing in Vermont law forces you to hook up to municipal power, water, or sewer. But "off-grid" doesn't mean "unregulated": DEC's wastewater and water supply permitting framework still applies based on what you build, even for a primitive camp once you move beyond a waterless toilet setup.

My honest bottom line: Vermont is workable for off-grid living, but it's not a free-for-all. The state cares most about water and wastewater, and your town cares most about zoning and dwelling type. Confirm both before you commit to land.
