I would slightly rephrase this to “too little housing.” Houses per se is not the answer, because just building more single family houses is not going to solve any problem that isn’t going to be massively outweighed by other problems that are exacerbated, as we’ve seen over the past 70+ years of suburban development. Increasing infill density and allowing for “missing middle” housing and mixed use development is the way to go, at least as far as the problems faced by your downstairs neighbors are concerned. This also must be complemented by prioritization of public transit and active transport as preferred modes of transportation in cities, coupled with redevelopment of parking lots and a moratorium on any new freeway construction, as more traffic lanes always and only ever make traffic worse.
