Can you stop a maintenance man from knocking on your door by mistake? No, stupid mistakes happen.
Do you have some sort of cause of action or reason to violate your lease when a maintenance man performs work that you requested when you're not home, even if you requested that it only occur when you're at home, based upon something that theoretically might have happened but did not actually happen? No, you do not.
