Zoning codes in the US are mostly copies of zoning code templates published decades ago, so even though every single place has its own, it's a little-modified version of what everyone else has. Even dense US towns are zoned against density. Somerville, Massachusetts had a rude awakening 5 years ago when they discovered the entire city is in violation of the zoning code. Every single home is out of compliance for one reason or another.
