Off-Grid Living in Calais, Vermont

Calais, Vermont is a small, rural town in Washington County, but don't let that fool you: it IS zoned. The town operates under the Calais Land Use & Development Regulations (CLUDR), first adopted by town vote in 2005 and amended several times since. Zoning here is handled locally by a Zoning Administrator, with a Development Review Board hearing appeals and conditional uses, and a Planning Commission handling bylaw changes. On top of the town layer, a lot of what off-gridders care about most, namely septic and water supply, is actually controlled by the State of Vermont, not the town. I want to be upfront that I'm reporting what I found in official sources, not offering legal advice, so always confirm specifics with the named office before you buy land or break ground.

Starting with zoning: Calais's regulations set up district-based use tables, and most construction, changes of use, subdivisions, and even some right-of-way work need a permit from the town. I did not find a Calais-specific rule spelling out tiny homes or RVs as dwellings; that gap means you should call the Zoning Administrator directly before assuming an RV or tiny house is treated like a standard home.

On building permits, Calais requires a zoning permit (via a Zoning Application or, for minor projects, a simpler Project Registration Form) through the Town Office. I did not find evidence of a separate municipal structural building code, which lines up with the broader Vermont picture of no statewide residential building code for most single-family constructions.

Septic and greywater are where the state, not Calais, calls the shots. Vermont's Department of Environmental Conservation has held statewide jurisdiction over wastewater and potable water permitting since 2007, covering new construction, subdivision, and system repairs. I did not find any Calais-specific greywater bylaw, so that too falls to the state's Wastewater System and Potable Water Supply Rules.

Rainwater harvesting looks fine: I did not turn up any Calais bylaw restricting it, consistent with Vermont's general allowance of non-potable rainwater use.

For wells, most of Calais relies on private wells regulated under state DEC siting and construction rules, except for the East Calais Fire District #1, a local water service area along Route 14 in East Calais.

Living off municipal utilities entirely appears legal here. I did not find a Calais bylaw mandating hookup to electric or water systems, but any off-grid home will still need town zoning sign-off and a state wastewater/water supply permit for however you handle septic and drinking water.
