Summary

Iowa Code 724.28 broadly preempts cities and counties from regulating firearms, ammunition, components, and accessories more strictly than state law.

724.28 Prohibition of regulation by political subdivisions - exception. 1. As used in this section, "political subdivision of the state" means a city, county, or township. 2. A political subdivision of the state shall not enact an ordinance, motion, resolution, policy, or amendment regulating the ownership, possession, carrying, legal transfer, lawful transportation, modification, registration, or licensing of firearms, firearms attachments, or other weapons when the ownership, possession, carrying, transfer, transportation, or modification is otherwise lawful under the laws of this state. An ordinance regulating firearms, firearms attachments, or other weapons in violation of this section existing on or after April 5, 1990, is void.
