Yes, stun guns are legal in Washington state for individuals 18 or older, provided they are not used unlawfully. Washington’s Revised Code § 9.41.250 permits possession without a permit, but local ordinances—such as those in Seattle or Spokane—may impose additional restrictions. Compliance with 2026 state firearm regulations, including background checks for certain devices, remains under review by the Washington Association of Sheriffs and Police Chiefs.
Key Regulations for Stun Guns in Washington
- Age Restriction: Only individuals aged 18 or older may purchase or possess a stun gun under RCW § 9.41.250.
- Prohibited Locations: Use or possession is banned in federal buildings, courthouses, schools (K-12), and airports, per RCW § 9.41.280 and local ordinances.
- Concealed Carry: While open carry is permitted, concealed carry in public spaces may require compliance with municipal laws, such as Seattle’s municipal code prohibiting stun guns in certain public areas.
Local law enforcement agencies, including the King County Sheriff’s Office, enforce these rules, with penalties ranging from misdemeanors to gross misdemeanors for violations. The 2026 legislative session may further refine device classifications under the Safety and Responsible Firearms Act, potentially expanding background check requirements for non-lethal weapons. Consult county-specific ordinances and the Washington State Patrol’s Firearms Unit for updates.
