are people that are convicted drug offenders of a meth lab legally allowed to manage an apartment complex?

having access to keys to other persons apartments. Has a history of sexual abuse; to which they lost there 2 children.
Fact: they plea bargained to snitch off another known meth lab inorder to not have to register as such offenders
i have come accross mini hidden camera around the premisesbut yet absolutely no postings anywhere stating “under survelliance”. They have been witnessed, under the pretences of just checking the smoke detector in a unit, going thru every single drawer and cabinet (not knowing that tenant was hiding inside. lists of complaints goes on and on!
