Ask your residence about it. Some guys from out of Ontario did that at my university. Their stuff was kept under lock and key in a locker in the Manager/Super's office. Every school is different but it's better to let them know then get kicked out of school.
I let mine know whenever I someone drop something off (I usually kept my stuff at my girlfriend's place), and they were chill about it. Just don't flash it around/keep it in the open/etc.
