Research notes
Act 181 establishes a tier-based Act 250 jurisdiction map (1A exempt for housing, 1B ≤50-unit housing exempt, 2 standard, 3 enhanced and currently suspended pending S.325). Tier maps are submitted by the 11 Regional Planning Commissions to the Land Use Review Board for approval; as of Q1 2026, 5 of 11 RPCs had submitted draft Tier 1A/1B maps. Effective dates per region begin January 2026 with rolling approvals continuing into 2027. Not a zoning preemption — modifies the parallel Act 250 state environmental permit track. Underwriting must carry act_250_jurisdiction_likely flag separately from zoning.
