What Is Vermont Act 250? Criteria, Costs, and Act 181 Changes

Vermont Act 250 is the state’s land use control law, codified at 10 V.S.A. Chapter 151, which requires developers to obtain a state permit before building projects that exceed certain size, housing, elevation, or subdivision thresholds. Enacted in 1970, it created nine District Environmental Commissions staffed by citizen volunteers who evaluate each proposal against ten environmental and community-impact criteria.¹ The law is in the middle of its biggest structural change since passage: Act 181 of 2024 introduces a tiered, location-based jurisdiction system that began phasing in during January 2026.

When a Project Needs an Act 250 Permit

Whether your project triggers Act 250 depends on its size, type, and location, and on whether the town where you’re building has adopted permanent zoning and subdivision bylaws.

Commercial or industrial construction on more than one acre in a town without zoning, or more than ten acres in a town with zoning.²
Housing projects of ten or more units within a five-mile radius during any five-year window, regardless of local zoning.²
Subdivisions dividing land into ten or more lots within a five-mile radius or the same district commission’s jurisdiction over any five-year period.³
Any commercial, industrial, or residential construction above 2,500 feet in elevation, regardless of size. Effective December 31, 2026, the threshold tightens to include construction at 2,500 feet, not only above it.²
State, county, or municipal construction involving more than ten acres.²

Acreage counts everything incidental to the project, including parking areas, lawns, leaching fields, and access roads. You cannot avoid jurisdiction by splitting a large project into smaller phases either. The statute looks at what a single person owns or controls across a five-mile radius, so phased construction on the same tract is treated as one project.

What Act 250 Does Not Cover

Farming and Forestry

Construction for farming, logging, or forestry below 2,500 feet is not considered “development” under Act 250 and does not need a permit.² When someone proposes non-farm development on land that is also farmed, only the portions of the property supporting the new development are reviewed, and the permit cannot impose conditions that conflict with required agricultural practices on the rest of the parcel.

Accessory on-farm businesses that store or sell qualifying farm products are also exempt, as is construction for on-farm processing where more than half the annual sales come from products grown on-site.³ Hosting events or farm-stay lodging does not qualify, and could still trigger a permit.

Housing in Designated Centers

Through January 1, 2027, certain housing projects in state-designated centers can bypass Act 250 entirely, provided they connect to public water and sewer (or have adequate soils for wastewater) and comply with local zoning and subdivision bylaws.⁴ The size of the exemption depends on the designation:

Designated downtowns: unlimited units, excluding river corridors and flood hazard areas.
Priority housing projects: unlimited units for mixed-income projects inside designated downtowns, neighborhood development areas, or growth centers, including a half-mile radius.
New town centers, growth centers, and neighborhood development areas: up to 75 units, excluding river corridors and flood hazard areas.
Designated village centers: up to 50 units, with a quarter-mile radius, excluding river corridors and flood hazard areas.

A 60-unit apartment building in a designated downtown that would normally face months of Act 250 review can proceed under local zoning alone. Confirm the designation status of the site with the municipality before relying on any of these carve-outs.

The Ten Criteria

Every application is measured against ten criteria at 10 V.S.A. § 6086. The commission will not issue a permit unless the project satisfies each one.⁵

Criterion 1 — no undue water or air pollution, with sub-criteria for headwaters, floodplains, shorelines, and wetlands.
Criterion 2 — sufficient water available for the project’s foreseeable needs.
Criterion 3 — no unreasonable burden on any existing water supply the project plans to use.
Criterion 4 — no dangerous soil erosion and no reduction in the land’s ability to hold water.
Criterion 5 — no unreasonable congestion or unsafe conditions on roads, waterways, or other transportation systems.
Criterion 6 — no unreasonable burden on the municipality’s ability to provide schools.
Criterion 7 — no unreasonable burden on local fire, police, sewer, or similar services.
Criterion 8 — no undue adverse effect on scenic beauty, historic sites, rare natural areas, or necessary wildlife habitat. A new sub-criterion for forest blocks and habitat connectors takes effect December 31, 2026.⁶
Criterion 9 — conformance with the state capability and development plan, covering local fiscal impact, loss of primary agricultural soils, productive forest soils, earth resources, energy conservation, settlement patterns, and the cost of scattered development. For agricultural soils, the applicant must show either that no farmland will be lost or that the project uses compact design and provides suitable mitigation.
Criterion 10 — conformance with any adopted municipal or regional plan.

Criterion 9 trips up applicants more than any other. Its sub-criteria (9A through 9L) reach everything from the fiscal strain of growth on a small town to whether a project encourages sprawl. Building on farmland invites heavy scrutiny under 9(B), and applicants should come prepared with a mitigation plan.

What You File and What It Costs

An application requires site maps with topography and property boundaries, engineering plans for wastewater and stormwater systems prepared by licensed professionals, traffic impact data, a written project description identifying all parties involved, and evidence that adjoining landowners have been notified (usually certified mail receipts or signed statements). Forms are available on the Natural Resources Board website.⁷

Fees scale with total construction cost. The minimum fee for an original application is $187.50, with a rate of $6.65 per $1,000 of construction cost up to $15 million and $3.12 per $1,000 above that. Publication and recording costs are charged on top.⁸ A project with $200,000 in construction costs runs about $1,518 in fees ($187.50 minimum plus $1,330 at the per-thousand rate). Amendment applications carry a lower minimum of $62.50.

Minor and Major Review Tracks

Act 250 sorts applications into minor and major tracks, and the difference drives your timeline. A project qualifies as minor when it thoroughly addresses all ten criteria and shows no significant adverse impact under any of them. Minor applications skip the public hearing unless an interested party, an agency, or the district commission asks for one.⁹

Major applications require a public hearing. After a complete filing, the district office notifies the applicant, the municipality, the municipal and regional planning commissions, the Agency of Natural Resources, and any adjacent towns near a boundary.¹⁰ The town clerk posts public notice. After the hearing record closes, the commission issues a written decision. Permits almost always carry conditions the developer must follow during and after construction, and those conditions run with the land indefinitely.¹ Straightforward minor applications can wrap up in a few weeks; complex major projects with contested hearings can take several months.

Penalties for Building Without a Permit

Building without a required Act 250 permit, or violating permit conditions, carries real financial exposure. Vermont’s Uniform Environmental Enforcement Act authorizes civil penalties of up to $85,000 per violation, with an additional penalty of up to $42,500 per day for ongoing violations.¹¹ The Land Use Review Board can also require a developer to tear down non-compliant construction or retrofit a project to meet the original permit conditions.¹² Because conditions attach to the land, buying a property with an existing Act 250 permit means inheriting every condition on it.

What’s Changing Under Act 181

Act 181, passed in 2024, replaces the one-size-fits-all jurisdictional model with a location-based tier system, phasing in through 2026.¹³

Tier 1A and 1B cover areas with existing infrastructure and growth capacity, where limited or no Act 250 review applies. Municipalities can apply for Tier 1A designation after their regional plan’s future land use map is approved, with applications accepted starting January 2026. A town granted Tier 1A status takes over administering any pre-existing Act 250 permits in those areas.¹⁴
Tier 2 covers everything that doesn’t fall into Tier 1 or Tier 3. The acreage, unit, and lot thresholds described above continue to apply here.
Tier 3 would cover ecologically sensitive areas including high-elevation and headwater zones, with additional protections. Agricultural and forestry uses would remain exempt even in Tier 3.¹⁵

Act 181 also introduced a “road rule” that would trigger Act 250 review for any new road longer than 800 feet, or any combination of roads and driveways exceeding 2,000 feet, effective July 1, 2026.¹⁶ The Board has suspended further work on both the Tier 3 rules and the road construction jurisdiction provisions because the Legislature has signaled it intends to repeal those portions of Act 181.¹³ Check the Natural Resources Board website for the current status of these provisions before relying on the tier framework for a project in planning.
