My neighbor that lives in the apartment below mine repeatedly makes ridiculous complaints of us making noise which include "being able to hear our fan" while we use it during a hot summer night, or that we are "talking too loud" when we are talking at a normal volume in our own rooms. It it important to note that his roommate has no issues with our supposed noise, just him.
A conversation with him last night began with him hammering loudly on our door with his fist and ended in him punching our door before storming off, and given that he seems to have very little control of his anger, my roommates and I are worried he might physically lash out. Given that he did not punch the door hard enough to leave physical evidence, what legal action can we take against a potentially violent neighbor to ensure the safety of my roommates and myself? Can this be considered a form of harassment?
Edit: I sent an email to the management company regarding his behavior informing them that I wanted it on record that I notified them in case something happens again and nothing was done on their part. But since "he complained first" we are in jeopardy of being evicted, because if he complains again we would be in violation of our lease agreement (which states we cannot annoy, disturb, inconvenience, or interfere with the quiet enjoyment of another tenant).
I looked up the noise laws for my city, and they state that the noise must be loud for a "reasonable" person of "average sensitivity." I definitely feel that my neighbor does not meet either of these criteria, but is there a way to go about showing this?
