People don't want to live next to a neighbor who builds a multi-family 3-story apartment complex out of wooden shipping pallets, blue tarps, and extension cords. We don't even want that anywhere, because it is a death trap fire hazard.

Cheap living is thus prohibited, though some large California cities look the other way sometimes when the homeless build homes of that nature.

You can't even build a new home without arc fault interrupters and centrally wired fire alarms. In some places, you'll even need to install solar. Of course this isn't cheap! We have simply banned cheap construction.
