What is Act 250 and does it apply to my project in Vermont?

Act 250 is Vermont's statewide land use and development law, codified at Title 10, Chapter 151 of the Vermont Statutes Annotated, requiring a separate permit from a District Environmental Commission for qualifying larger developments. Whether it applies depends on project size and type, such as acreage disturbed or number of housing units, and it applies on top of, not instead of, any required local zoning approval.

Can I build a duplex by right in Vermont?

In many areas, yes. Act 47 of 2023, the HOME Act, requires municipalities to allow duplexes by right on lots served by municipal water and sewer, overriding local single-family-only zoning in those serviced areas. Confirm the specific parcel's water/sewer service status and local bylaw, since rural or unserviced lots may not be covered.

Does every Vermont town have zoning?

No. Vermont's roughly 250 municipalities are enabled, not required, to adopt zoning bylaws under Title 24, Chapter 117 of the Vermont Statutes Annotated, so a number of smaller, more rural towns have limited or no formal zoning. Even in unzoned towns, however, a qualifying project may still trigger Act 250 review at the state level.

How do I find parcel and zoning data for a property in Vermont?

The Vermont Center for Geographic Information (VCGI) maintains a statewide parcel-level GIS layer built from town grand lists and the state's E911 addressing and parcel program. Zoning district information itself is still set and published locally, so pairing VCGI's parcel data with the relevant town's zoning bylaw and map is the standard approach.

Vermont zoning: how it works and what you can build

Vermont layers ordinary town-level zoning under Title 24 with a second, mandatory statewide review process, Act 250, that applies to qualifying larger developments regardless of local approval — making dual-track permitting the defining feasibility fact for Vermont projects.

How zoning works in Vermont

Vermont's roughly 250 towns and cities adopt their own zoning bylaws under the Municipal and Regional Planning and Development Act, codified at Title 24, Chapter 117 of the Vermont Statutes Annotated. Vermont has a strong town-meeting tradition of local self-governance, but formal municipal land-use authority is statutory, so every local zoning bylaw ultimately traces back to that Chapter 117 delegation. Adoption of zoning is not mandatory for every town, and a number of Vermont's smaller, more rural municipalities have limited or no formal zoning bylaws.

Layered on top of local zoning is Act 250, Vermont's landmark 1970 land use and development law, codified at Title 10, Chapter 151. Any project that meets certain size or scale thresholds, such as larger subdivisions or commercial and industrial development above defined acreage, needs a separate Act 250 land use permit from a District Environmental Commission, independent of and in addition to any local zoning approval. This dual-track system is essentially unique among the states and is often the single biggest driver of schedule and cost uncertainty on a Vermont project, particularly for anything beyond an in-town infill scale.

Vermont has been legislatively active on housing in recent sessions. Act 47 of 2023, known as the HOME Act, allows duplexes by right in areas served by municipal water and sewer, curtails local parking minimums, and exempts some qualifying infill development from Act 250 review. A follow-on 2024 Act 250 modernization law restructured Act 250 jurisdiction into geographic tiers, reducing the review burden for development inside existing town and village centers while tightening it in rural and forested areas, a shift partly motivated by the flooding risk exposed by Vermont's severe 2023 floods.

Who holds the zoning power

Land-use authority in Vermont is delegated by statute, not assumed — these are the acts a zoning ordinance in Vermont has to trace back to.

Municipal and Regional Planning and Development Act Vermont Statutes Annotated, Title 24, Chapter 117: Enables Vermont towns and cities to adopt zoning bylaws, subdivision regulations, and municipal or regional plans.
Act 250 (Vermont Land Use and Development Law) Vermont Statutes Annotated, Title 10, Chapter 151: A second, state-level permitting layer requiring District Environmental Commission review for qualifying large-scale development, on top of any local zoning approval.

Major cities and their codes

The enabling act sets the ceiling; the municipal code is what a project is actually reviewed against. The 7 largest Vermont jurisdictions and the codes they administer:

Vermont — municipal zoning codes
City	Zoning code
Burlington	Burlington Comprehensive Development Ordinance (CDO) Vermont's largest city and only true urban core; waterfront redevelopment and downtown density are the state's most active zoning debates.
South Burlington	South Burlington Land Development Regulations Chittenden County's fastest-growing suburb, home to Vermont's largest retail and commercial corridor.
Rutland	City of Rutland Zoning Ordinance Western Vermont's regional hub, a former marble-industry city with legacy industrial-zoned land available for redevelopment.
Essex	Town of Essex Development Regulations Chittenden County town split between the incorporated Essex Junction village core and a more rural surrounding town, with mixed suburban and rural zoning.
Colchester	Town of Colchester Development Regulations Lake Champlain shoreline town experiencing Burlington-adjacent suburban growth.
Montpelier	City of Montpelier Zoning Regulations The nation's smallest state capital by population; severe 2023 flooding forced a rethink of downtown floodplain zoning.
Bennington	Town of Bennington Land Use and Development Regulations Southern Vermont hub near the New York and Massachusetts borders, mixing historic mill buildings with newer commercial development.

Recent reforms

State-level changes override or preempt what a local ordinance says — these are the Vermont reforms that move the numbers on a real site.

2024 Act 250 Modernization Law Restructures Act 250 jurisdiction into geographic tiers, easing review for development in existing town and village centers while tightening it in rural and forested areas.
2023 Act 47 (HOME Act) Statewide zoning reform allowing duplexes by right in areas served by water and sewer, reducing parking minimums, and exempting some qualifying infill development from Act 250 review.

Parcel & GIS data

The Vermont Center for Geographic Information (VCGI) maintains a statewide parcel-level GIS layer aggregated from town grand lists and the state's E911 parcel program, giving Vermont relatively strong statewide parcel data coverage for its size.

Parcel-level feasibility in Vermont waits on that data being ingested and the ordinances encoded — the waitlist below is what sets the order.

Zoning by city

The statute sets who may zone; the city's own code sets what you can build. One guide per Vermont city below, explaining the district codes that appear on its zoning map — 85 district codes across Vermont so far.
