>Contact your state representative and ask them to do something about the building codes. It's a completely voluntary problem. American buildings are noisy because we decided that was okay.

Congratulations on finding an equally terrible and bad for everybody apartment-living analog to the sort of suburbanite Karen opinion that underpins meddling HOAs and busybody municipal codes.

If you want a quieter apartment pony up to live in a nicer one. Don't force the rest of society to shoulder the expense.

You should probably read The Market for Lemons. It's incredibly difficult to predict from the buyer's perspective how noisy an apartment will be. This is [one reason] why we have regulations.

You assume I'm in US, while I'm not. Not even EU. I know building owner personally and the only factual way is to evict those people. The only problem is that building owner is leasing them an apartment, and you can't evict people basing on household noises, even if they are driving me insane.
