Oregon law preempts most local firearm regulation but permits limited city and county rules in public buildings and on adjacent grounds.
ORS 166.170 establishes that the authority to regulate firearms, ammunition, and components is generally vested exclusively with the Legislative Assembly, blocking most local ordinances. However, ORS 166.171 through 166.176 carve out narrow exceptions allowing counties and cities to limit possession of loaded firearms in public buildings and to require concealed handgun license holders to comply with limited posted restrictions. Local governments may not impose taxes, registration, or possession bans broader than statutory authority. Recently, voter-approved local sanctuary measures conflicting with state law have faced legal challenges grounded in this preemption framework.
Local ordinances exceeding statutory authority are typically void and unenforceable in Oregon courts.
