Off-grid land in Vermont: what to check before you buy
Living off the grid in Vermont still means meeting the state rules for any new home. You need a state Wastewater System and Potable Water Supply permit before you build, the house must meet the Residential Building Energy Standards, and if the land is on a Class 4 road the town is not required to maintain it.

Do I need a septic and well permit to build on land in Vermont?
Yes. Under 10 V.S.A. § 1973 and § 1-301 of the Wastewater System and Potable Water Supply Rules, you need a permit from the state before constructing a new building, a new water supply or a new wastewater system, and before subdividing land. The permit is needed before construction starts, which the rules define to include foundation excavation and site work that affects the water supply or wastewater system.
Can I turn a seasonal camp into a year-round home?
Maybe, but check the permit first. The Department of Environmental Conservation says a permit may be needed when a change of use increases water use or changes how the system operates, for example converting a seasonal home to year-round use or adding a bedroom.
Does the energy code apply to an off-grid house?
New homes in Vermont must meet the Residential Building Energy Standards (30 V.S.A. § 51). The builder, or a licensed engineer, architect or accredited home energy rating organization, signs an RBES certificate, fixes it near the electrical panel or heating equipment, sends a copy to the Department of Public Service and records it in the town land records. Where a town requires a certificate of occupancy, the RBES certificate must be provided first. The Department's 2025 handbook lists at least 200-amp electrical service for each new building, so ask the Department how that applies to a home with no utility connection.
What is a Class 4 road and who maintains it?
Under 19 V.S.A. § 302 the selectboard decides which town highways are Class 4. Towns must keep Class 1, 2 and 3 highways in good repair in all seasons (19 V.S.A. § 310(a)). Class 4 highways may be maintained only to the extent the town decides is needed (§ 310(b)), so many are not plowed or repaired. Check the road class with the town clerk before you buy land on one.
Is it legal to live off the grid in Vermont?
Vermont's rules are about permits rather than grid connection. A new home needs a state Wastewater System and Potable Water Supply permit and must meet the Residential Building Energy Standards, and the town's zoning bylaws also apply. Ask the town and the state about your plan before you buy.
Do I need a permit for a septic system or well in Vermont?
Yes. A Wastewater System and Potable Water Supply permit from the Vermont Department of Environmental Conservation is required before building a new water supply, wastewater system or building (10 V.S.A. § 1973).
Will the town plow a Class 4 road?
Not necessarily. Towns must keep Class 1 to 3 roads in repair in all seasons, but Class 4 roads may be maintained only to the extent the town decides is needed (19 V.S.A. § 310).
Does Act 250 apply to off-grid land?
It depends on the size of the project. See our Act 250 guide and ask the District 7 coordinator in St. Johnsbury for a jurisdictional opinion before you subdivide or develop.
