This bill establishes limitations on the authority of counties and cities in Iowa regarding the regulation of hemp production. Specifically, it prohibits these local governments from adopting or enforcing any ordinances or regulations that would restrict or prohibit the location of hemp production by USDA licensees in areas zoned for commercial or industrial purposes.

The bill introduces new sections to the Iowa Code, specifically Section 335.2B for counties and Section 414.34 for cities, clearly stating that local authorities cannot impose regulations that would interfere with hemp production in designated zones. This legislative change aims to create a more favorable environment for hemp production by ensuring that local governments cannot impose additional restrictions on USDA-licensed producers operating in commercial or industrial areas.
