Arizona Revised Statutes section 13-3108 preempts almost every Maricopa County firearm rule, voiding any county ordinance on registration, magazine limits, sales, or transport beyond state law. Only narrow discharge and county-property authority survive across unincorporated land.
ARS section 13-3108 declares firearms a matter of statewide concern and bars Maricopa County from regulating ownership, sale, transfer, transport, licensing, or storage. Senate Bill 1334 in 2016 strengthened the preemption by authorizing civil penalties up to fifty thousand dollars and lawsuits against any non-compliant county or city. The Maricopa County Sheriff still enforces state firearm law, the Board of Supervisors may bar discharge in densely populated unincorporated areas under ARS section 13-3107(C), and county zoning may apply standard commercial siting to gun shops. The county cannot require permits to own, register guns, or impose waiting periods; older park-carry restrictions were repealed after preemption was tightened.
County officials enforcing a preempted firearm rule face civil penalties up to fifty thousand dollars under ARS section 13-3108(D), and a private party may sue Maricopa County for damages and attorney fees.
