Buying Land in Chittenden County, Vermont

No county zoning -- 4 cities and 15 towns, each on its own

Even in Vermont's most populous and most urbanized county, land-use authority still sits entirely at the municipal level, not the county. Chittenden County contains 4 cities -- Burlington (the shire town and Vermont's largest city), South Burlington, Winooski, and Essex Junction -- plus 15 towns: Bolton, Buel's Gore, Charlotte, Colchester, Essex, Hinesburg, Huntington, Jericho, Milton, Richmond, Shelburne, St. George, Underhill, Westford, and Williston. Every one of them adopts and administers its own zoning ordinance and Development Review Board, exactly as the rest of Vermont's towns do -- there is no Chittenden County planning department or building inspector, and Burlington's own zoning code has no bearing on what's permitted in, say, Huntington or Bolton.

The Chittenden County Regional Planning Commission (CCRPC) serves as the region's regional planning commission -- coordinating transportation, housing targets, and a regional future land-use plan across the county's municipalities -- but like every Vermont RPC, it holds no zoning or permitting authority of its own. It's a genuinely useful resource for regional context (housing targets, future land-use mapping, municipal plan drafting for towns that lack the staff capacity, including Buel's Gore's own municipal plan), but it cannot approve or deny a specific project; that stays with the municipality.

Burlington's urban core and the county's genuinely rural outer towns

Chittenden County is honestly a study in contrast rather than a uniform rural county. Burlington itself -- roughly 44,400 residents as of 2024 -- is Vermont's only real urban center, with the density, infrastructure, and zoning intensity that implies: multi-family zoning, municipal water and sewer, and a real downtown core, none of which describes most of the rest of Vermont, including most of this same county. Suburbanizing towns like South Burlington, Williston, Essex, and Colchester carry their own more conventional residential and commercial zoning patterns shaped by decades of growth pressure radiating out from Burlington.

At the other extreme sits Buel's Gore, an unincorporated "gore" -- a leftover unclaimed tract from Vermont's original town-survey era -- with a 2020 population of just 29 and no elected municipal government at all; CCRPC handles its municipal planning function directly. Roughly two-thirds of the Gore's approximately 3,126 total acres is not privately owned at all (only about 1,105 acres are in private hands), the terrain is steep enough that buildable sites are genuinely scarce, and CCRPC's own future land-use mapping designates the entire Gore as Rural -- Conservation, General, or Agriculture/Forestry, or Resource-Based Recreation. Rural towns further out, like Huntington and Bolton, sit closer to Buel's Gore's reality than to Burlington's. The practical lesson for a buyer: "Chittenden County" tells you almost nothing about what a specific parcel will actually allow -- the municipality does all the work.

Affordable-housing set-asides in Burlington and South Burlington

Chittenden County's two largest cities each run their own inclusionary zoning ordinance requiring a share of units in larger residential projects to be priced as affordable housing. Burlington's version, first adopted in 1990 and amended as recently as March 2023, requires 15% to 25% of units (depending on the market-rate price point) in projects of five or more new units to be price-restricted for 99 years, targeting roughly 70% of area median income for ownership and 65% for rental. South Burlington runs a separate ordinance limited to specific districts (its City Center Form Based Code District, Transit Overlay District, and certain Hinesburg Road-area lands) with a historically higher, 12-unit trigger. The two cities' rules are not interchangeable -- see our dedicated housing-mitigation-requirements page for Chittenden County for what actually applies where.

Richmond's repeated Winooski River flooding

Downstream of Bolton and Jonesville, Richmond's village center -- Volunteers Green and Bridge Street -- has flooded three separate times in roughly a year: July 2023, December 2023 (the Winooski's third-highest recorded crest at that point), and July 2024. The town has responded with an active process, including a dedicated December 2024 Selectboard meeting on flooding mitigation and published FEMA buyout/elevation/relocation guidance for property owners. This is a distinct reach and event history from Washington County's Montpelier/Barre flood story upstream on the same river -- see our dedicated flood-zones page for Chittenden County for the full event history and what to check before buying nearby.

Act 250 District 4 and the Essex Regional DEC office

Chittenden County is its own dedicated Act 250 district -- District 4 -- rather than sharing a commission with neighboring counties, likely reflecting the county's comparatively high development volume; by contrast, Franklin and Grand Isle share District 6, and Caledonia, Essex, and Orleans share District 7. The same statewide jurisdictional thresholds and the ongoing Tier-system overhaul (Tier 3 taking effect December 31, 2026) our Vermont state hub describes apply here regardless of the district's size. Septic and water-supply permitting for Chittenden County runs through the Vermont DEC's Essex Regional Office in Essex Junction, which issues Water/Wastewater System permits directly at the state level -- including, notably, for parcels inside Burlington itself, since this state-level jurisdiction doesn't carve out an exception for Vermont's largest city.

What to check before buying land in Chittenden County

Confirm zoning district, permitted use, and dimensional requirements with the specific municipality -- Burlington's zoning office for a Burlington parcel, the relevant town's zoning administrator everywhere else, and CCRPC directly for anything in Buel's Gore, which has no local office of its own. If the parcel is on more rural land in the county's western or eastern towns, verify actual buildable acreage rather than assuming the whole lot is developable -- Buel's Gore is the extreme example, but slope, wetlands, and public/conserved land reduce usable acreage in several of the county's outer towns. Plan on an Act 250 District 4 review for anything crossing the standard thresholds, and a Vermont DEC Essex Regional Office Water/Wastewater permit for any new or replacement septic system and water supply, regardless of how urban or rural the specific parcel is.
