An act relating to Act 250 location-based jurisdiction

H.730 updates Vermont's Act 250 land use law by clarifying "Tier 3" rules, which designate high-priority conservation areas (like river corridors and sensitive habitats). It requires the Land Use Review Board to define Tier 3 boundaries, explain why certain resources aren’t protected, and provide written notice to property owners in Tier 2/3 areas about upcoming rule changes. The bill also creates a de minimis construction exception (e.g., sheds under 200 sq. ft.) and temporarily exempts priority housing projects in designated downtown areas from Tier 3 rules until July 2027. These changes directly affect property owners in conservation zones, local municipalities, and developers navigating land use permits.
