The City of St. Louis Zoning Upgrade (ZOUP) is a critical tool for implementing the goals of the Strategic Land Use Plan of the City’s Comprehensive Plan (SLUP), formally adopted in February 2025. Informed by robust community outreach conducted during the SLUP process and additional targeted engagement, it will update St. Louis’s zoning districts, development standards, maps, and administrative procedures. This work will ensure that processes, regulations, and outcomes align with community goals, and bring the City up to date with contemporary best practices in zoning.
