Things got very heated with my upstairs neighbor last night, was I out of line?

I live in a downstairs unit, building has two floors. I own and the tenant above me rents, prior to her there was another tenant that lived there. Before I rant and complain about noise, I’ve lived in apts my whole life. Prior to moving here, I only recall living in one place where the upstairs neighbors were terrible because they had little children. This neighbor and the previous one are single, live alone but do have guests. My current neighbor is also in her mid twenties; which I found out yesterday. I thought the previous neighbor was a prick doing it intentionally but it isn’t any better with this neighbor. This tenant, for now, is only noisy when she has guests. Based on yesterday’s confrontation, I’m not sure how she’s going to act moving forward. I first approached this upstairs neighbors fall time last year, when she was home alone about the noise. My issue is when it’s noisy past 10 PM, the cops have confirmed there’s such a thing as quiet hours. As I explained myself yesterday, I know there may not be sufficient soundproofing but there should be some consideration in the late hours.

Like I said, I approached my current neighbor for the first time fall last year when she was home alone. The second time, she had friends over late for Christmas and I approached her that time too. The next day, she apologized, we exchanged names and she said to knock on her door if there’s an issue again. Fast forward later in Jan 21, she has this woman over and the woman has a heavy foot/dropping things late. Per her request, I knocked on the door and she did not answer, even though she told me to knock if there’s issues. So I was offended and call the cops, the cop stops by and speaks with her upstairs. This cop is familiar with me, he came by in 2020 when I complained about the previous neighbor. I found out yesterday the cop apparently told her that I did the same thing with the previous neighbor.

Last night, she had people over and the tv could be heard through the walls/loud laughing. I was annoyed, as the same instance took place last Sunday but I kept my mouth shut. I call the cops because knocking on the door is useless based on my attempt to speak with her in Jan. The cop calls me in advance to speak over the phone, trying to minimize contact due to covid versus approaching me in person. I give him a run down and he says that this is to be expected in apt living. I told him yes to a degree but there should be consideration in the late night. He agreed but I could tell he was sticking to his initial point.

He comes by, knocks on her door and politely says there’s a noise complaint. She says “Figures. Thank you Officer we will turn it down”. And the second she closes the door, the music goes back on. I was not having it, I open the door and yell to him from my place as he was still outside. She opens the door, her guests were nearby listening and it got very confrontational.

I was not cussing but my tone was very stern and according to the officer “rude”. I mentioned again my concern with noise in the late hours. My neighbor had a party in the daytime around a month ago, she warned me in advance and I said okay. My point being is there is not an issue, considering it’s not taking place late. She was just focusing on how she was so considerate to tell me in advance, missing the fact that I am aggravated with her other instances of being loud late. She mentioned that last time when the cop came over, she told me to knock on her door but I quickly chipped in and reiterated how she ignored me. She started crying (crocodile tears) and her friend consoled her. Telling her “don’t cry she isn’t worth it”. I said something smart and she told me to shut up, I can’t remember what I said.

The neighbor was playing the victim saying she’s 25 and young, I said “oh and I’m not?” The other guy that was with her approached me and said he turned the music down. She is missing the point that the issue is doing this late in the night, wanted to exchange numbers with me so I can tell her when there’s a problem. But clearly I was told to knock on her door last time and she did not acknowledge me. My tone was very direct and the cop said I was being rude, not helping the situation. Saying that we need to get along and find a way to work each other’s schedules. And telling me that she is allowed to have guests over late, there’s a caveat to silent hours (10PM-6AM). I came across as the villain here and I thought it was unfair. The friend that was bitchy with me ended up leaving while the cop was the still there and the other guy staying till around 2 AM today. I could tell she was upset when the cop left, the door slammed and I could hear talking. Shortly after, she and the guy went out for food and came back. I could hear when he left, it quieted down after that. I am worried that she’s going to make my life hell now. I just feel l need to stand my ground, I don’t get why she’s crying. As I said yesterday, if the shoe was on the other foot I would have liked to see how that would’ve played out. The cop was saying she’s nice and trying to be accommodating, I never said she wasn’t nice I just said she and her guests are noisy in the late hours.

I was close to selling my place earlier this year but did not want this woman to chase me out of my home. I do feel bad, I have never had confrontation with a neighbor to this degree and it doesn’t feel nice. I want to avoid her every chance I get moving forward. I just don’t want her to make noise intentionally because of yesterday’s tiff. AITA? I would appreciate everyone’s perspective.
