As the Director of a housing project and someone with 20 years in the business I can say that you should expect a letter from an attorney in about five days. Depending on the how aggressive the main office wants to be, you may find that there has been a warrant sworn out on you, if that be the case, I suggest that you not mention being an X-LEO to your cell mates.
Maintenance never got the door open so he could announce himself, you had an open work order and when the maintenance man realized that someone was in the unit, but not answering, he attempted to go away.
Management would be negligent in allowing a hostile, and potentially dangerous work place, if they allowed you to remain on the property.
Edited to add. Years ago, I was maintenance man and was going to help out an old lady who had a big load of groceries. She said if I would go up to her room (413) and get her shopping cart out of her storage room, she would appreciate it. Off I go, the elevator stops and I go to the room and use my master key to get in (I didn’t realize I was on the third floor) about the time I said to myself "Therese no shopping cart in hear" I turn to see the lady from 314 holding a .38! Thankfully she had been raised with guns and knew how to handle it, and she was a good sport about the whole thing.
