Iowa has simple, permissive stun gun laws โ legal for adults 18+ without a permit, with one notable local exception in Denison and Crawford County. Every major Iowa university bans them on campus regardless.
What Iowa Law Actually Says
Iowa Code ยง 724.8 permits adults 18+ to possess stun guns without a permit. No size or voltage restrictions. Prohibited locations include school grounds. The one notable local exception: Denison and Crawford County ban stun guns entirely under local ordinance.
Campus Reality
University of Iowa, Iowa State, UNI, Drake, and Grinnell all ban stun guns on campus. Personal alarms are the only universally unrestricted self-defense option.
What to Carry Instead
For Iowa students, a personal alarm and pepper spray are the practical choices. The She's Birdie Personal Alarm ($29.99) is unrestricted everywhere. The SABRE Campus Safety Pepper Gel ($11.99) is legal under Iowa law with no restrictions.
Denison/Crawford County students: Stun guns are banned locally. Personal alarm and pepper spray are your options.
