I have messages with my roommate and guests about the mean woman in 3A who complained only when I had overweight guests that they were noisy in one particular bedroom. I also contacted her rich family and told them I would be willing to put a recording device in her apartment to make sure she wasnt being bullied with undocumented noise complaints. But I also had strange triad looking guests who intentionally made noise bumping their suitcases up the stairs and also left their suitcases on the landing despite my instructions.
I don't know if that is enough to defend against a personal lawsuit. I stopped hosting and only my family is in my apartment and my mother was very offended when she in the kitchen and the woman used a broom handle to beat her ceiling (our floor). My mother asked I can't move a chair or a ladder or drop a curtain rod helping my daughter in my own building? This woman also used the broom handle to poke holes in the ceiling around her steam risers. She is a menace and we have recorded screaming answering machine messages and a video tape. If the other gangster and social justice warrior tenants want to join a lawsuit, what can I do about it?
But as the previous tenant who was hosting probably illegally, don't you owe the landlord your assistance? I have no problem showing my records because i was SO cheap - even the inspector said it - I was obviously trying to make my monthly rent and FAILED frequently.
