Ohio state law prohibits anyone from carrying a concealed weapon on a college campus, regardless of whether the school is public or private. Statute 2923.126 says that even someone with a license to carry a concealed weapon cannot do so on “[a]ny premises owned or leased by any public or private college, university, or other institution of higher education, unless the handgun is in a locked motor vehicle or the licensee is in the immediate process of placing the handgun in a locked motor vehicle.” A bill has been proposed that would allow students to carry concealed firearms on campus, if their schools allow it.
There is currently no Ohio law against open carrying of firearms in public, including on campuses, although schools have their own rules regarding this. Ohio State University’s Code of Student Conduct prohibits any possession or storage of firearms, even when permitted by law.
