Off-Grid Living in Milton, Vermont

If you're eyeing off-grid life in Milton, Vermont, here's what my research turned up, with the caveat up front that I'm not a lawyer and this isn't a substitute for calling the actual offices below.

Zoning: Milton is zoned, town-wide. The Town administers its Unified Development Regulations (UDR), adopted under Vermont's Municipal and Regional Planning and Development Act (24 VSA Chapter 117, a state enabling law). Unless a use is specifically exempted under the UDR, land development in Milton needs zoning review from the Planning & Zoning office, and bigger projects go before the Development Review Board (DRB). This is a town-level layer sitting on top of state authorization, so don't assume rural land is a blank slate.

Tiny homes, RVs, portable structures: restricted. Milton's UDR (Section 1102, per the town's posted regulations) treats portable structures without a foundation the same as permanent buildings for permitting purposes, and it specifically says vehicles not used for their manufactured purpose generally can't count as a dwelling. So parking an RV or tiny house on wheels as a permanent residence is going to draw scrutiny from the Zoning Administrator.

Building permits and codes. Interior work on an existing single-family home doesn't need a Milton zoning permit, but new construction does. The town's permit process also points applicants to Vermont's Residential Building Energy Standards (RBES), a state program, and to UDR sections on erosion and stormwater control if you're disturbing soil. The Zoning Administrator has a stated 30-day window to act on a complete application.

Septic and wells: this is state jurisdiction, not town. Since 2007, Vermont's Department of Environmental Conservation (DEC) has held universal jurisdiction over wastewater systems and potable water supplies, including for cabins, yurts, and single-family homes. Any new well or septic system, even a small off-grid cabin, needs a Wastewater System and Potable Water Supply Permit from DEC. Milton doesn't appear to add its own separate septic rule; it defers to the state.

Greywater falls under the same DEC wastewater program as a non-conventional system, but I couldn't confirm any Milton-specific bylaw addressing it directly, so treat it as state-regulated and confirm details with DEC.

Rainwater harvesting: I found no Milton ordinance restricting it, at either the town or state level, in the materials reviewed. That's not a guarantee, just an absence of any restriction found.

Off-grid utility living: no rule forces a grid hookup in Milton or in Vermont generally, but that doesn't exempt you from permitting. Any occupied structure still needs a zoning permit, and any plumbing or water supply still needs the state DEC wastewater/water permit.

Bottom line: Milton's town-level zoning and UDR control what you can build and where, while Vermont's DEC controls water and waste infrastructure regardless of town. Both layers apply, and it's worth calling ahead before you buy land or start building.
