I recently bought a condo with HOA rules that state that if you rip up the carpet, you have to replace it with something of equal sound-damping quality. After moving in I discovered that my upstairs neighbors are the loudest walkers in existence. I don't want to complain to management without talking to my neighbors first but I did ask the MC is they could tell me how they manage condo renovations to make sure that they are compliant with the HOA. I was told that you bring them a form letting them know you are doing something, then they make sure it is compliant. She said that in her experience, illegal flooring does happen. I looked up the property records and the same people have owned the condo since the 1990s. I have no clue when the flooring was installed but thankfully no unknown secondary buyer is involved to complicate the issue (though I think the people upstairs might be renters). What exactly do I do? The person I bought the condo from installed a floating wood floor to be compliant. If no one has complained before, will the upstairs people get to keep their loud flooring just because they never got caught?
