Weapon laws (Title 18, Ch. 33 IC)
Idaho does not have purchase permits, gun registration, or gun-owner licensing. There are no limits on magazine capacity or weapon types. There is no waiting period mandated for firearm purchases and private gun sales are legal. Concealed weapon licenses are shall issue, no license is required to carry a concealed firearm outside of city limits, no license is needed for any Idaho resident (even within city limits), and open carry is legal. Permitless concealed carry is for Idaho residents only.

'No guns' signs on private property do not have the force of law. A refusal to leave or disarm when requested would be trespassing. Hotels may legally prevent you from bringing in a firearm. 39-1805 and 39-1809
You may carry a firearm in an establishment that serves alcohol. You may not carry a concealed firearm while intoxicated. 18-3302B
