Act 250 Permit: Criteria, Application, and Appeals

You need an Act 250 permit in Vermont when your development crosses the jurisdictional thresholds set out in 10 V.S.A. Chapter 151, and you get one by applying to the district commission for your region and showing the project satisfies all 10 statutory criteria covering water, soil, traffic, municipal services, scenic and wildlife impacts, planning conformance, and agricultural soils.¹ Act 181 of 2024 reshaped the program in 2025 and 2026, introducing a tiered map that exempts some growth areas from review entirely and tightens protections elsewhere, so the first question for any Vermont developer is which tier the parcel sits in.²

When Act 250 Applies to Your Project

Act 250 jurisdiction turns on three things: where the land is, what you’re building, and how much of it you’re building. Under Act 181, Vermont is sorting land into tiers that change the threshold calculus.²

Tier 1A areas, with strong infrastructure for growth, are fully exempt from Act 250, including subdivisions and changes to existing projects.
Tier 1B areas exempt housing projects of up to 50 units on 10 acres or less; larger commercial and industrial work still goes through review.
Tier 2 covers everything not designated Tier 1 or Tier 3, and the traditional thresholds below still apply there. Beginning July 1, 2026, new road and driveway construction in Tier 2 independently triggers jurisdiction.
Tier 3 is reserved for critical natural resource areas with additional protections. The Land Use Review Board has suspended work on Tier 3 implementation pending possible legislative changes.

Outside the Tier 1 exemptions, the long-standing acreage-based triggers remain in force. Whether yours applies depends in part on whether your municipality has adopted both permanent zoning and permanent subdivision bylaws.³

Commercial or industrial construction on more than one acre in a town without both bylaws (a “1-acre municipality”).
Commercial or industrial construction on more than 10 acres in a town with both bylaws (a “10-acre municipality”).
Housing projects of 10 or more units (including condominiums, cooperatives, or mobile homes) within a five-mile radius over any continuous five-year period.⁴
Subdivision creating 10 or more lots of any size within a five-mile radius over a five-year period.⁵
Municipal, county, or state construction involving more than 10 acres, regardless of local bylaws.
Any commercial, industrial, or residential construction at or above 2,500 feet elevation.⁵

A few less obvious triggers catch people off guard. A communication tower that extends 20 feet or more above an existing structure, or a new tower 50 feet or more above ground, requires a permit regardless of lot size. Groundwater withdrawals exceeding 340,000 gallons per day from a single site require one as well. Farming, logging, and forestry operations are excluded from the commercial or industrial definition, so they don’t count toward acreage thresholds.⁵

Changes to an Existing Property

Act 250 reaches more than new construction. If your property already holds an Act 250 permit, a “material change” (any physical alteration or change in use that significantly affects a finding, condition, or conclusion of the existing permit) requires a permit amendment. Expanding a building’s footprint or converting a warehouse to a restaurant are typical examples.

If your development predates Act 250 (built before June 1, 1970) and never had a permit, a “substantial change” to the property triggers Act 250 jurisdiction for the first time when the change could cause a significant adverse impact under any of the 10 criteria. In both scenarios the threshold question is whether a “cognizable change” (any physical change or change in use) has occurred at all. Contact your District Coordinator before starting work if there is any doubt.

The 10 Criteria Your Project Must Meet

Every Act 250 application is measured against the 10 criteria in 10 V.S.A. § 6086. The district commission won’t issue a permit unless the applicant demonstrates the project clears each one.⁶ Most of the burden of proof falls on the applicant. For wildlife habitat and a few related sub-criteria, opponents bear the burden of showing a project fails.

Water, Air, and Soil (Criteria 1–4)

Criterion 1 prohibits undue water or air pollution and incorporates sub-standards on headwaters, waste disposal, water conservation, flood hazard areas, stream banks, and shorelines. A project in a flood hazard area must not restrict floodwater flow or cause erosion. Criterion 2 requires sufficient water supply for the development’s foreseeable needs. Criterion 3 prohibits an unreasonable burden on existing water sources. Criterion 4 addresses soil erosion, requiring the project not reduce the land’s capacity to hold water to the point of creating dangerous conditions.⁶ Projects on steep terrain or near wetlands tend to require detailed engineering and hydrogeological studies to satisfy these.

Traffic and Municipal Services (Criteria 5–7)

Criterion 5 covers transportation. The project must not cause unreasonable congestion or unsafe conditions on highways, waterways, railways, or airports, and applicants need to show it incorporates transportation demand management and safe connections to pedestrian, bicycle, and transit networks where appropriate. The Vermont Agency of Transportation recommends a formal traffic impact study when a project will add 75 or more peak-hour vehicle trips to the state highway system.⁷ Criterion 6 bars unreasonable burdens on municipal educational services. Criterion 7 does the same for other municipal and governmental services, including police, fire, and sewage.

Aesthetics, Wildlife, and Natural Areas (Criterion 8)

Criterion 8(A) requires that the project not have an undue adverse effect on scenic or natural beauty, aesthetics, historic sites, or rare and irreplaceable natural areas. A “rare and irreplaceable natural area” is a significant natural community of a certain size, condition, and quality that cannot be restored once disturbed.⁸ Criterion 8(A) also protects necessary wildlife habitat and endangered species, and here the burden of proof flips: opponents must demonstrate the project would destroy or significantly imperil habitat or species. Even then, the commission balances the public benefit against the environmental loss. Applicants must describe steps to avoid, minimize, and mitigate impacts and provide a review letter from the Department of Fish and Wildlife’s Wildlife Program.

Effective December 31, 2026, Criterion 8 expands to add protection for forest blocks and habitat connectors. A permit won’t be granted for development within or partially within a forest block or habitat connector unless the applicant demonstrates the project won’t cause an undue adverse impact on that resource.⁶

Growth, Agricultural Soils, and Local Plans (Criteria 9–10)

Criterion 9 requires conformance with the state’s capability and development plan and carries the most complex sub-criteria of any. The commission weighs anticipated costs for education, highways, water, sewage, police, fire, and other services against the town and region’s ability to absorb them, and can impose conditions to prevent undue burden.⁹ Criterion 9 also protects primary agricultural soils. A permit on these soils will only be granted when the applicant shows the work won’t reduce agricultural potential or provides suitable mitigation for any loss, often through conservation easements or off-site agricultural preservation. Productive forest soils and earth resources receive similar treatment under additional sub-criteria.

Criterion 10 requires conformance with any duly adopted local or regional plan. A project that conflicts with the town plan faces an uphill fight at the district commission.

How to Apply

An Act 250 application needs detailed site plans showing buildings, roads, and utilities relative to property boundaries, along with topographical maps illustrating slopes, wetlands, forests, and other natural features. Depending on the project you may also need wildlife habitat assessments, stormwater management plans, traffic impact analyses, and soil investigations. The Land Use Review Board hosts all official forms on its online portal, and you should contact the District Coordinator before you start to confirm which form applies, since data doesn’t transfer between forms if you pick wrong.¹⁰

Fees

For construction projects, the fee is $6.65 per $1,000 of construction costs on the first $15 million and $3.12 per $1,000 above that. An additional $0.75 per $1,000 of the first $15 million goes to the Agency of Natural Resources for its review, bringing the effective rate to $7.40 per $1,000 for most projects.¹¹ Specialized fees apply to other project types:

Lot creation: $125 per lot.
Earth resource extraction: the greater of the standard construction fee or $0.02 per cubic yard for the first million cubic yards, and $0.01 per cubic yard above that.
Master plan review: an added $0.10 per $1,000 of total estimated construction costs on top of the regular construction fee.

The minimum fee is $187.50 for an original application and $62.50 for an amendment, and no single application fee can exceed $165,000. Fees are calculated within the application and paid by paper check mailed to the designated district office.¹²

What Happens After You File

You submit the application electronically through the ANR Online portal and upload exhibits to the Board’s FTP site. The district office assigns a project number within one to two days and sends a Notice of Initial Application Filing to you, the landowner, the municipality, planning commissions, the Agency of Natural Resources, and any adjacent municipalities on the boundary.¹⁰ The town clerk posts the notice publicly.

The district commission then classifies the application as minor or major review. A minor track applies when the application thoroughly addresses all 10 criteria and the project presents no significant adverse impact under any of them. No public hearing is held on a minor application unless one is requested by an interested party, a local or state agency, or the commission itself.¹³ A major review involves a public hearing where the commission takes testimony from the applicant, neighbors, state agencies, and anyone granted party status. Adjoining property owners, the municipality, planning commissions, and state agencies receive direct notice of every application and can submit written comments; others who want to present evidence or cross-examine witnesses can petition the district commission for formal party status.¹⁴

After deliberations close, the commission has 20 days to issue a written decision approving, conditionally approving, or denying the application.¹⁵ An approved permit often carries conditions governing construction methods, operating hours, stormwater controls, or landscaping.

Penalties for Building Without a Permit

Building without a required Act 250 permit carries real consequences. The statute makes any violation of Chapter 151 or its rules punishable by a fine of up to $500 per day of the violation, imprisonment of up to two years, or both.⁴ More commonly, the Land Use Review Board pursues civil enforcement through administrative citations, and a separate citation can be issued for each day a violation continues. Maximum daily fines are tiered by severity:¹⁶

$3,000 per day for extracting earth resources 400 or more cubic yards beyond permitted quantities, failing to reclaim a site as directed, failing to maintain erosion controls, and any violation classified as more than minor.
$2,000 per day for extracting resources beyond permitted dates or in smaller excess quantities, failing to maintain landscaping or vegetative buffers or lighting, and violations classified as minor.
$1,500 per day for failing to file post-construction certification, missing a construction completion deadline, erecting unpermitted signs, and noise restriction violations.
$1,000 per day for failing to file required reports or documentation.

A respondent who voluntarily waives the right to contest a citation pays 75% of the imposed penalty. Daily fines accumulate quickly, which is why asking the District Coordinator for a jurisdictional opinion before you break ground is worth the time, even when you believe your project falls below the thresholds.

Appealing a Permit Decision

Any person aggrieved by a decision of a district commission or District Coordinator can appeal to the Environmental Division of Vermont Superior Court within 30 days of the decision. Parties by right, including the applicant, the municipality, and state agencies, have the same deadline. The Environmental Division conducts a fresh review rather than simply checking whether the district commission followed proper procedures, so new evidence can sometimes be introduced. Act 181 directed the Land Use Review Board to study whether appeals should remain in the Environmental Division or move to the Board itself, so the venue may change in the coming years.¹⁷ For now, Environmental Division is the forum.
