Iowa Firearms Preemption

Iowa has a broad firearms preemption statute that bars political subdivisions from enacting or enforcing firearm regulations more restrictive than state law. The preemption is codified in Iowa Code Section 724.28.

Statutory Authority

• Iowa Code Section 724.28 - State preemption of local firearms regulation
• Iowa Const. art. I, Section 1A - Iowa Right to Keep and Bear Arms amendment (ratified November 2022, applies a strict-scrutiny standard to laws restricting the right)

Scope of Iowa Code Section 724.28

Iowa Code Section 724.28(1) provides that a political subdivision of the state shall not enact an ordinance regulating:

• The ownership of firearms
• The possession of firearms
• The legal transfer of firearms
• The lawful transportation of firearms
• The registration of firearms
• The licensing of firearms

The statute applies to counties, cities, townships, school districts, and any other political subdivision of the state.

Limits and Carve-Outs

A political subdivision may:

• Regulate the discharge of firearms within its jurisdiction (subject to Iowa Code Section 724.28(2) limits)
• Prohibit weapons in its own buildings as long as adequate security is provided (such as metal detectors and armed guards), with detailed conditions specified in Iowa Code Section 724.28(3)
• Manage public-property safety incidental to other lawful police powers

Iowa Code Section 724.28(3): Local Buildings

Under Iowa Code Section 724.28(3), a county or city may restrict the carrying, possession, or transportation of firearms in or on public property under the political subdivision's control only if it provides reasonable safety measures, including but not limited to: armed guards, metal detection devices, or other comparable measures, available to the public at the entrance.

This carve-out is narrow. A bare "no weapons" sign on a city office without screening or armed security does not satisfy Iowa Code Section 724.28(3) and may not be enforceable as a criminal matter against a lawful carrier (though removal from the property as a trespasser remains possible).

Iowa Const. art. I, Section 1A

Iowa voters ratified the Iowa Right to Keep and Bear Arms amendment in November 2022. The amendment provides:

The right of the people to keep and bear arms shall not be infringed. The sovereign state of Iowa affirms and recognizes this right to be a fundamental individual right. Any and all restrictions of this right shall be subject to strict scrutiny.

By imposing a strict-scrutiny standard, the amendment requires that any firearms restriction be narrowly tailored to serve a compelling government interest. This standard reinforces the statutory preemption and makes local firearms regulation more vulnerable to legal challenge.

Enforcement and Remedies

A person aggrieved by an ordinance that violates Iowa Code Section 724.28 may file suit in district court seeking declaratory and injunctive relief. Although Iowa does not statutorily authorize attorney-fee recovery in every preemption case, prevailing parties may pursue available statutory or common-law fee shifting under other Iowa rules.

Common Preempted Local Rules

The following types of local ordinances are typically preempted under Iowa Code Section 724.28:

• Local restrictions on the type, capacity, or features of firearms a resident may possess
• Local registration or "permit-to-acquire" systems beyond what state law authorizes
• Local restrictions on lawful transportation of firearms across a city or county
• Local age requirements stricter than state law
• Local fees or licensing for firearms ownership

Permitted Local Activity

The following remain permissible:

• Local discharge ordinances (e.g., prohibiting discharge of a firearm within city limits except in self-defense or at an approved range)
• Local zoning that addresses firing ranges and dealer location (subject to constitutional limits)
• Building and conduct rules in local-government buildings that comply with Iowa Code Section 724.28(3)
• Local nuisance and public-safety provisions of general applicability

Practical Effect

Iowa firearm carriers can generally rely on statewide uniformity. A person who is lawfully carrying under Iowa Code Section 724.4C (permitless) or under an Iowa Permit to Carry Weapons may travel from Des Moines to Sioux City to Davenport without encountering different local concealed-carry rules.

Federal Preemption

State preemption does not displace federal law. Federal restrictions on firearm possession (18 U.S.C. Section 922) and federal prohibited places (18 U.S.C. Section 930, the federal Gun-Free School Zones Act under 18 U.S.C. Section 922(q)) apply in Iowa irrespective of Iowa Code Section 724.28.
