Prohibits the issuance of permits for construction of data centers for one year in St. Louis

HB 3369 temporarily halts the issuance of permits for new data center construction in St. Louis for one year, until August 28, 2027. It directly affects developers and businesses seeking to build or expand facilities that process, store, or distribute data - including AI training, crypto mining, cloud computing, and server farms - within St. Louis city limits (not county areas). The bill pauses permit approvals for new applications but allows existing submissions made before August 28, 2026, to proceed under current rules. This is a procedural pause, not a permanent ban, and applies only to city-level permit decisions. The bill is pending in the legislature after introduction in February 2026.
