Act 250 Update: Continued Progress, but Execution Risks Are Becoming Clearer
This week’s testimony before the Senate Natural Resources Committee showed continued progress on working toward technical corrections to Act 181, the Act 250 reform adopted in 2024. But it also made clear that execution, not intent, is now the central challenge. Act 181 set an ambitious direction, encouraging housing in planned growth areas while protecting critical natural resources. Whether it succeeds will depend on whether the implementation phase delivers clarity, consistency, and confidence.
Regional planning commissions reported steady movement on Tier 1B mapping, with five commissions having submitted plans and three already receiving feedback from the Land Use Review Board. State level review of regional future land use maps is an important step. At the same time, RPCs were clear that evolving guidance and iterative feedback from the board are creating uncertainty. Regions that submitted early may be held to different standards than those submitting later, not because policy changed, but because interpretation is still developing. That inequity matters, especially when communities are being asked to make long-term planning decisions.
Tier 1B remains one of the most promising elements of Act 181. Eligibility is expected to cover roughly two to three percent of Vermont’s land area, a meaningful expansion from the approximately 0.3 percent previously eligible for downtown and village center incentives but still likely insufficient to meet the state’s housing needs. Tier 1B allows up to 50 housing units without Act 250 review in mapped growth areas. The intent is clear: give communities a real tool to support housing. The risk is that uncertainty in mapping, review standards, or timing undermines that goal.
Housing targets developed by the Vermont Housing Finance Agency and the Department of Housing and Community Development further reinforced that Vermont’s challenge is not hitting a precise unit count, but unlocking the housing market and building momentum. That requires signaling, through policy and implementation, that Vermont is open to housing in the places it has planned for growth.
Tier 3 remains the most concerning element of implementation. The Land Use Review Board described draft mapping and rulemaking focused on habitat connectors and other sensitive areas. While the board emphasized that Tier 3 is intended to be limited in scope and to avoid overlap with existing regulations, even board members acknowledged that many Vermonters do not yet understand how Tier 3 will work or whether it will apply to them. That lack of clarity is not a minor issue. It directly affects landowners, municipalities, and housing developers trying to make decisions now.
The board has asked for additional time to refine Tier 3 maps, narrow affected areas, and conduct outreach, including extending effective dates for Tier 3, the road rule, and Criterion 8C to December 31, 2027.
Tier 1A implementation raised similar red flags. Requiring municipalities to assume responsibility for administering existing Act 250 permits is a real deterrent for communities that might otherwise opt in. Testimony clarified that permits would transition gradually as they are amended, but without clear statutory guardrails, uncertainty remains. Communities need assurance that participation will not come with unmanageable administrative risk.
The Senate Natural Resources Committee appears to recognize these risks. Discussion around S.325 has focused on technical corrections that improve clarity, align timelines, and reduce unintended barriers to housing, rather than reopening last year’s policy debate.
From the Vermont Chamber’s perspective, the path forward is clear. Act 181 can work, but only if implementation prioritizes predictability, consistency, and momentum. That means clear standards from the Land Use Review Board, fair treatment of early and late adopters, realistic timelines, and a permitting system that supports housing in growth areas rather than slowing it through uncertainty.
The Vermont Chamber will continue to advocate for these corrections. It is the difference between a reform that delivers housing and economic vitality, and one that stalls under the weight of its own complexity.
