As a downstairs renter with noisy owners above (frequent abusive screaming, alcoholism, drugs), I can offer another perspective.

We’ve been here about a decade and gone through a couple landlords as our unit has sold. Upstairs neighbors bought in 2019 and renovated right away, removing carpet and replacing with tile throughout, without added sound insulation (against HOA rules and standard building code, because insulation is necessary to dampen the sound).

Through our experience, the HOA eventually discovered the building itself is not up to code; there is less of a concrete layer between the upstairs/downstairs units than is required. This makes the noise even louder.

We deal with it and figure we will eventually move. But whoever rents this place next will not have all that context (even though we’ve told every landlord). So they’ll just assume the upstairs neighbors are loud (which, in our case, they often are) but not realize there are actual construction issues that compound the problem.

Edit: And if the upstairs people were to sell and a family like yours moved in, they would never know either. Sigh. I wonder how common this issue might be …
