I'm a college student and I live in my own apartment which allows all pets, and seeing as how reptiles don't destroy flooring the manager has no issue with it. I have a zilla 40 gallon breeder critter cage with the sliding screen top and a lock latch. I just got a small mini lock and it works like a charm.
Most apartments do not care and would rather you have a snake than a person who lets their dog tear up the place.
However, I would really find a place that explicitly states there's no issue against snakes or else you could have unwanted problems. I would look for a place that's not a high rise and is smaller, these places are usually more lenient and managers are willing to work with you. My apartment manager loves my snake.
I forgot to mention if you do ask about the policy mention you were thinking about getting a "small" reptile and gauge their reaction and see what the actual policy is.
