The City of St. Louis Planning and Urban Design Agency (PDA) and the Zoning Section of the Building Division are proud to announce the launch of a comprehensive process to overhaul the City’s zoning code—the Zoning Upgrade: a modern code to meet the moment—marking the first major rewrite and map update since the mid-twentieth century.
 

The Zoning Upgrade is a critical step in implementing the Strategic Land Use Plan (SLUP), legally adopted by the Planning Commission in early 2025 after extensive community engagement. Building upon that momentum, the zoning update will modernize how land use is regulated in the City, improving clarity, consistency, and responsiveness to community priorities. The City has engaged a team led by Code Studio, a planning firm specializing in zoning, to guide the process and embed best practices from across the country into St. Louis’s new code.
