Excuse me if I’m wrong but central hvac system, the word ‘complex’ instead of just ‘apartment building’, no junkies, soundproofed walls… doesn’t sound like ‘working class high density housing’ to me. At least that’s not a thing where I’m from.
Now a ‘major city’ without rats and roaches??? It has to be a cold as fuck city, definitely not a thing in temperate climates.
Not a yank, as you’ve already discovered. But to answer your question, I don’t know about suburbs and the like, my experience is only with apartment building hoas and no, you can’t leave them. The thing is part of the property is shared–like corridors, stairways, lifts, any space that is not a home, even the facades…
