Off-Grid Living in Colchester, Vermont

I've been digging into what off-grid living actually looks like in Colchester, Vermont, and here's my honest read after going through the town's regulations and the state's rules.

First, the big picture: Colchester is a zoned town. It has adopted comprehensive Development Regulations under Vermont's Planning and Development Act, most recently updated (per the Vermont ACCD bylaws archive) with zoning district changes effective May 3, 2023. That means what you can do on any given parcel, lot size minimums, setbacks, allowed uses, depends on which zoning district it falls in. There's an interactive map on the town's Plans & Regulations page to check a specific property, and I'd treat that as step one before buying land here.

On dwellings, tiny homes, and RVs, I couldn't find Colchester-specific language addressing this directly. It would fall under the town's use tables (Table A-1 for permitted/conditional uses, Table A-2 for dimensional standards), but I don't have a confirmed answer, so this is a call-the-Planning-and-Zoning-office question before you commit to any plan.

Building permits are enforced at the town level. Colchester's Building Inspector acts as the "Municipal Official" under state statute (24 V.S.A.), and the town has adopted its own building code standards. Every zoning and building permit here requires a close-out inspection, so budget time for that step, though I don't have specifics on how long it typically takes.

Septic is where things get more state-driven. Colchester is largely on individual septic systems (the town's own memo notes this drives its larger minimum lot sizes), but the actual permitting authority is Vermont's Department of Environmental Conservation, which has held universal jurisdiction over wastewater and water supply permitting statewide since July 1, 2007. That covers new construction, subdivisions, and system repairs or replacements. Composting toilets and greywater setups fall under this same state wastewater program, I couldn't find a separate Colchester ordinance addressing greywater specifically, so the state baseline is what applies unless you hear otherwise from the town.

Rainwater harvesting looks permitted, I found no town-level restriction on it, so the state baseline applies here too.

Wells are state-regulated through DEC's Regional Office Program, which issues permits for private potable water supplies. Colchester's larger lot sizes (tied to septic needs) mean more physical space between properties, which can matter for well and septic siting, but there's no separate town well ordinance I could confirm.

Living disconnected from utilities looks doable in principle, Colchester's own guidance says the town will still issue zoning permits and certificates of occupancy regardless of how a property handles utilities. But you'll still need to satisfy state water and wastewater permitting for whatever on-site systems you use. This isn't a loophole around code compliance, it's compliance through a different set of systems.

Bottom line: Colchester doesn't ban off-grid living, but it doesn't hand it to you either. Every piece, zoning district, building permit, septic, well, runs through either the town or the state, and you'll want to confirm your specific parcel and plans with both before you break ground.
