Iowa Pepper Spray and Stun Gun Laws (2026)

Iowa has no dedicated statute for pepper spray, and none of its weapons chapters mention chemical sprays by name. Stun guns are a different story: Iowa's general definition of "dangerous weapon" specifically names an electric immobilizing device, which pulls stun guns into a real set of rules that a plain keyword search for "stun gun" mostly misses, because the operative term throughout Iowa Code Chapter 724 is "dangerous weapon," not "stun gun."

Jurisdiction scope: This page covers Iowa state law only, principally Iowa Code Sections 702.7, 724.1 through 724.28, and 708.2. It does not cover Iowa's professional permit-to-carry-weapons statute in full detail, or local ordinances, which Iowa's preemption statute (Section 724.28) already displaces for firearms and other weapons regulated by the state.

Is pepper spray legal to carry in Iowa?

Yes, and Iowa has no dedicated statute setting an age minimum, capacity or formula limit, purchase channel, or possession restriction for pepper spray or any other chemical self-defense spray. Iowa Code Chapter 724, the state's core weapons chapter, defines "offensive weapon" (Section 724.1: machine guns, large-bore weapons, destructive devices, ballistic knives) and, by cross-reference, "dangerous weapon" (Section 702.7), but neither definition, nor any other section in Chapter 724, Chapter 708 (assaults), or Chapter 719 (contraband and obstruction), names a chemical spray, tear gas, mace, or oleoresin capsicum device.

That silence carries one legal consequence worth stating precisely. Section 702.7's "dangerous weapon" definition, which drives Iowa's weapon-based sentencing enhancements, requires that the item be "designed primarily for use in inflicting death or injury upon a human being... and... capable of inflicting death upon a human being when used in the manner for which it was designed," or, for an item not designed as a weapon, that it be used in a manner showing intent to inflict death or serious injury and be capable of inflicting death. The definition then adds a list prefaced "Dangerous weapons include but are not limited to," naming among its items "any portable device or weapon directing an electric current, impulse, wave, or beam that produces a high-voltage pulse designed to immobilize a person," but no chemical spray. Because that list is expressly open, the absence of a spray from it decides nothing by itself; the work is done by the two branches above. Because pepper spray is not named and is not ordinarily capable of inflicting death, using it against someone in Iowa does not, on this statute's text, automatically trigger the "dangerous weapon" assault enhancement (Section 708.2(3), an aggravated misdemeanor) the way using a stun gun does. Iowa's sale-to-minor restriction, Section 724.22, is scoped to a rifle, shotgun, pistol, or revolver and their ammunition; nothing in that section bars an adult or a retailer from selling or giving pepper spray to a person under eighteen.

Are stun guns legal to carry in Iowa?

Legal for an adult who is not otherwise disqualified, and no permit is required to carry one. The reason Iowa's stun-gun rules are easy to miss is that the operative statutory term is "dangerous weapon," defined in Section 702.7 to include, by name, "any portable device or weapon directing an electric current, impulse, wave, or beam that produces a high-voltage pulse designed to immobilize a person." Iowa Code Chapter 724 then regulates "dangerous weapons" as a category, which sweeps in stun guns alongside firearms, knives with a blade over five inches, and other listed items, without using the phrase "stun gun" itself in most of the operative sections.

Section 724.5 states that a weapons-carry permit being available "shall not be construed to impose a general prohibition on the otherwise lawful unlicensed carrying or transport, whether openly or concealed, of a dangerous weapon, including a loaded firearm." Read together with the absence of any separate stun-gun licensing chapter, that means an adult who is not disqualified can carry a stun gun in Iowa, openly or concealed, without a permit. One standing duty applies to anyone carrying a dangerous weapon in Iowa: under Section 724.4D, a person carrying one "whose behavior creates a reasonable suspicion that the person presents a danger to the person's self or others shall cooperate with an investigating officer." The section states no separate penalty.

Disqualification is where the real restrictions live. Section 724.8B prohibits a person from carrying any dangerous weapon, including a stun gun, if that person is ineligible for a weapons-carry permit under Section 724.8, subsections 2 through 6 (addicted to alcohol; probable cause, based on documented specific actions at least one of which occurred within the two years before the application, to believe the person is likely to use a weapon unlawfully or in a way that would endanger the person or others; subject to Iowa's felon-weapons statute (Section 724.26); convicted within the previous three years of a serious or aggravated misdemeanor defined in chapter 708 that did not involve a firearm or explosive; or federally barred from possessing a firearm), and the same section independently prohibits carrying any dangerous weapon by a person who illegally possesses a controlled substance under Iowa Code chapter 124, subchapter II, or who is committing an indictable offense. Section 724.8B does not incorporate Section 724.8's separate under-18 ground (subsection 1); the age line for a minor carrying a stun gun runs through Section 724.4E, discussed below, not through Section 724.8B. Violating Section 724.8B is a serious misdemeanor. Separately, Section 724.4C makes it a serious misdemeanor to carry a dangerous weapon on or about the person, or within immediate reach in a vehicle, while intoxicated under the standards in Section 321J.2(1)(a), (b) or (c). Subsection 2 excepts a person carrying or possessing the weapon in their own dwelling, place of business, or on land they own or lawfully possess, and excepts transitory possession or use during an act of justified self-defense or defense of another, so long as it lasts no longer than is immediately necessary to resolve the emergency. Using a dangerous weapon in the commission of a crime is an aggravated misdemeanor under Section 724.4 (a class "D" felony instead, under Section 708.8, for a person who goes armed with a dangerous weapon intending to use it against another without justification; Section 708.8 adds that this intent "shall not be inferred from the mere carrying or concealment of any dangerous weapon itself").

Minors get a specific, narrower rule for stun-type devices than for other dangerous weapons. Under Section 724.4E(1), a minor who goes armed with a dangerous weapon concealed commits a serious misdemeanor. But Section 724.4E(3) carves out a separate, lighter offense: "A minor who goes armed with a dangerous weapon that directs an electric current impulse, wave, or beam that produces a high-voltage pulse designed to immobilize a person, whether concealed or not, commits a simple misdemeanor." Iowa treats a minor carrying a stun-type device, concealed or in the open, as a lesser offense than a minor concealing most other dangerous weapons. On the supply side, Section 724.22's sale-to-minor restrictions reach only a rifle, shotgun, pistol, or revolver and their ammunition; nothing in that section bars an adult or a retailer from selling or giving a stun gun to a person under eighteen.

Iowa also has a notable protective rule most states do not: Section 724.8A bars the governing board of a Board of Regents university or a community college from adopting any policy that prohibits carrying a nonprojectile stun-type device (one that does not fire a projectile) on campus. That protection does not apply to a convicted felon, and Board of Regents universities may still restrict such devices inside the physical structures of an associated stadium or hospital.

Where you can't carry either device, and preemption

Iowa's contraband statute, Section 719.7, lists a "dangerous weapon, offensive weapon, pneumatic gun, stun gun, firearm ammunition, knife of any length or any other cutting device, explosive or incendiary material, instrument, device, or other material fashioned in such a manner as to be capable of inflicting death or injury" among the items barred from a jail, detention facility, community-based correctional facility, correctional institution or juvenile detention facility. The list is prefaced "includes but is not limited to," and possessing contraband of that type is a class C felony under Section 719.7(4)(a). It is a facility-security rule rather than a general civilian restriction, but the penalty is the harshest on this page. Chapter 724 contains no other place-based restriction naming a stun gun or pepper spray outside Section 719.7. Two of the chapter's other place-based statutes reach only firearms: Section 724.4A's enhanced-penalty "weapons free zone" (within 1,000 feet of a school or on public park property) applies to "a firearm or offensive weapon," and Section 724.4B's school-grounds ban applies to "a firearm of any kind." Neither of those terms covers pepper spray or a stun gun.

Iowa's preemption statute, Section 724.28, bars a city, county, or township from enacting any ordinance, rule, or policy regulating the ownership, possession, carrying, transfer, transportation, modification, registration, or licensing of "firearms, firearms attachments, or other weapons" when that conduct is otherwise lawful under state law; a violating local ordinance is void, and a person adversely affected by one may sue for damages and attorney fees. Because "other weapons" is not limited to firearms, and a stun gun is a "dangerous weapon" under Section 702.7, this preemption statute reaches local stun-gun ordinances as well, unlike states whose preemption statutes are written around firearms specifically. A political subdivision may still screen for and restrict dangerous weapons, including stun guns, inside its own buildings if it provides armed security and screening (Section 724.28(4)).

Federal law: what it does and does not reach

No federal statute regulates a civilian's purchase or possession of pepper spray or a stun gun. Federal law matters in three places.

Federal buildings. Under 18 U.S.C. § 930(a), whoever knowingly possesses or causes to be present "a firearm or other dangerous weapon in a Federal facility (other than a Federal court facility)" faces a fine, imprisonment of up to 1 year, or both. Subsection (e) sets up to 2 years for a federal court facility, and subsection (b) up to 5 years where the weapon is intended to be used in a crime. Section 930(g)(2) defines the term:

The term "dangerous weapon" means a weapon, device, instrument, material, or substance, animate or inanimate, that is used for, or is readily capable of, causing death or serious bodily injury, except that such term does not include a pocket knife with a blade of less than 2½ inches in length.

The definition names neither device. Whether a particular spray or stun gun is "readily capable of" causing serious bodily injury is a question of fact the statute does not answer. Subsection (d)(3) exempts "the lawful carrying of firearms or other dangerous weapons in a Federal facility incident to hunting or other lawful purposes," and subsection (h) requires notice of the ban to be posted at each public entrance. A "Federal facility" is "a building or part thereof owned or leased by the Federal Government, where Federal employees are regularly present for the purpose of performing their official duties."

Air travel. The Transportation Security Administration's screening rules, which are agency policy rather than statute, bar both devices from carry-on bags. One 4 fl. oz. (118 ml) container of mace or pepper spray is permitted in checked baggage if it has a safety mechanism to prevent accidental discharge, and sprays containing more than 2 percent by mass of tear gas (CS or CN) are prohibited in checked baggage. Tasers, stun guns and other electro-shock weapons may travel in checked baggage only if transported so the device cannot discharge accidentally. Airlines may set stricter rules.

National parks. National Park Service regulations prohibit possessing, carrying or using a "weapon" in a park area except as the regulations provide (36 CFR 2.4(b)(1)). 36 CFR 1.4 defines "weapon" to include an "irritant gas device" and any "weapon the possession of which is prohibited under the laws of the State in which the park area or portion thereof is located."
