Off-Grid Living in Bristol, Vermont

I've been digging into what it actually takes to live off-grid in Bristol, Vermont, and the short version is: this is a zoned town, and your septic/water setup runs through the State of Vermont, not the county (Vermont doesn't have county health departments handling this).

Zoning. Bristol is not unzoned. The town regulates land use through its Unified Development Regulations (UDR), adopted under Vermont's Municipal and Regional Planning and Development Act (24 V.S.A. Chapter 117), and most recently amended by voters in November 2024. There are several districts (village, rural agricultural, rural conservation, etc.), each with its own dimensional standards and use tables. A zoning permit is generally required to develop raw land, so before you do anything, I'd talk to the town's Zoning Administrator.

Dwellings, tiny homes, RVs. I couldn't confirm from the UDR text I reviewed exactly how Bristol treats tiny homes or RV occupancy. That's a real gap, not an assumption of "yes" or "no." Call the Zoning Administrator's office directly and ask before you buy land or move a structure in.

Building permits. Bristol issues zoning permits for development, and many projects also have to meet the Vermont Building Energy Standards, which is a state-level requirement layered on top of the town's permit. Note that Governor Scott signed an executive order in September 2025 reinstating the 2020 Energy Standards as an option, so ask the town or the state's Energy Code Assistance Center which standard currently applies to your project.

Septic and greywater. This is state territory, not town or county. Since 2007, Vermont's Department of Environmental Conservation (DEC) has held universal jurisdiction over wastewater systems and potable water supplies statewide, including composting toilets and greywater reuse tied to a new structure or lot subdivision. Bristol falls under DEC's Essex Junction Regional Office, which covers Addison, Chittenden, Franklin, and Grand Isle counties. You'll need a Wastewater System and Potable Water Supply Permit from DEC, not the town.

Rainwater harvesting. I didn't find any Bristol-specific restriction, and the state baseline appears permissive, but treat this as a lighter-confidence read since there's no dedicated local rule to point to.

Wells. DEC also sets statewide well siting and construction standards, including a required setback between a leachfield and a private well, and a mandatory wastewater assessment when a property with a well/septic changes hands. No added Bristol-specific well rule turned up in my research.

Going off-grid on utilities. I found no Bristol ordinance forcing a hookup to municipal electric, water, or sewer. That said, you'll still need a town zoning permit for the structure and a DEC water/wastewater permit for however you handle water and waste off-grid.

Bottom line: two authorities matter here, the Town of Bristol for zoning and building permits, and the State of Vermont (DEC) for anything involving water or wastewater. Confirm specifics before you commit to land.
