Have some housing in the "good" parts, but use the rest another way.

This is the road to hell. Anyone can always come up with an excuse for why something shouldn't be done and if you accept them all then nothing ever gets built and people can't afford to live.

Construction requirements should be for things that are profoundly dangerous and not obvious, like having circuit breakers on electrical circuits or constructing buildings that are structurally sound or having fire exits.

Anybody can see how many windows or bathrooms a place has and you don't die if you get your natural light from going outside or occasionally have to wait in line for the facilities.
