Welcome to the horrors of the rental life, Empathic_One. I can totally empathize with your pain and frustration over your noisy neighbor and apartment manager's inconsistent enforcement of a quiet building.

That tenant sounds like a nightmare. In your lease, it should state something about quiet hours. I have a noisy neighbor as well and despite my regular complaints to my landlord via email about her, she persists in being obnoxiously loud on a regular basis.

I could sue her, file a police report too. But then what if I win, she gets evicted, and the next neighbor is just as noisy? It's rinse and repeat. It feels like an uphill battle. Some people are just assholes. They think they can be noisy neighbors without consequences.

The one thing you don't want to do is confront him yourself. That could have negative consequences for you, esp if he's some kind of crazy person. Just keep complaining to your landlord. I'm hoping the more I complain, the more likely my landlord will just evict this woman I live across from in my bldg. and I'll get a quiet neighbor again. The rest of my bldg. is very quiet.

If worse comes to worse, you may want to see if you can save up a security deposit and 1st month's rent and move to a different apartment in your same building. Sounds like a hassle I know, but that would be a last resort type of thing.

Good luck. Noisy neighbors are awful people.
