Google 'missing middle'. There are tons of laws restricting what kind of homes can be built so we end up with whole swaths of cities being a single kind of home that is unaffordable and doesn't work for a lot of people.
We no longer build the types of urban homes that were popular when this was primarily an agrarian country, and this only happened because of zoning laws?
it sounds ironic, but much of the shift to suburban development patterns in the USA was indeed driven by the Great Migration into cities – specifically, the migration of formerly-enslaved Black Americans out of the rural south and into cities. US public policy was very explicit about disinvesting in cities and destroying vibrant urban neighborhoods, replacing them with freeways and parking lots.
today, large portions of US cities are zoned for exclusively single-family homes, and other zoning requirements like parking minimums, and minimum setback and lot sizes continue to slow urban, transit-oriented redevelopment.
