My question involves criminal law for the state of: california

I am on parole in california and i am living with my mom, and a person who rents a room from her. is parole allowed to search their rooms?, i am told by my parole agent if the doors are locked i should be alright, but what if the other tenant is using the bathroom, they should not be required to have theire belongings gone through, they did not sign anything and have nothing to do with me, is this legal, how would i bring this to the attention of my parole officer or police, if they are attempting to do this?
