Except for concealed carry permit holders carrying concealed firearms, no person may possess a firearm in a building in Colorado in which the chambers, galleries, or offices of the state general assembly or any member, officer, or employee of the general assembly are located, or in which a legislative hearing or meeting is taking place.1

Local governments may enact regulations prohibiting open carrying of firearms in a building or specific area within the local government’s jurisdiction, as long as signs are posted to that effect.2

No person, regardless of a permit to carry a concealed handgun, may carry a concealed handgun into a public building at which security personnel and electronic screening devices are permanently in place at each entrance, each person entering the building is screened, and persons carrying weapons are required to leave them with security while in the building.3

Colorado prohibits any person from possessing, without legal authority, a loaded firearm in, or carrying or bringing a loaded firearm into, any public transportation facility.4
