We had a similar problem, when we first moved up here my fiancee parents found the apartment for us, and told us everything was fin etc etc. Since we couldn't get up to look and ask ourselves we trusted and agreed, about a week before we moved in we were told only our cat was allowed.
Anyway we've been here almost a year, had two inspections, had over a week noticed for them.
I hid a 4x2x2 tank for my bearded dragon in a bachelor apartment along with my four snakes.
Trust me, unless you give them cause you shouldn't have any problems. We've been trying to move out but it just isn't in the stars as far as money or being able to find a place.
I wish you luck and trust me as long as you mind your Ps and Qs you really shouldn't have much of a problem.
