CO HB1093

Expands the definition of "anti-growth law" to include local land use laws in census urban areas that decrease permitted residential density or uses below July 1, 2025 levels without ensuring corresponding density increases elsewhere in the jurisdiction

Clarifies that "anti-growth law" applies to "generally applicable" land use laws that explicitly limit population growth or cap development/building permits for residential projects

Exempts land containing or directly adjacent to wildlife crossing structures identified in Colorado Parks and Wildlife high priority habitat maps from anti-growth law restrictions

Allows municipalities to seek judicial determination on the legality of proposed land use ordinances restricting development before an election is ordered, with election timelines tolled during litigation

Takes effect 90 days after legislative adjournment, unless a referendum petition is filed, in which case it would go to voters in November 2026
