I’m American and to my knowledge it’s normally a code enforcement issue, which is typically left up to local (i.e. city or county) governments. There are also Homeowners’ associations, but that isn’t a legal thing and just depends on the neighborhood and whether or not it has one.
I live in the Atlanta area and have lived in both Fulton and Cobb county. In my experience, Cobb county was far more stringent with code enforcement. I was once given a warning because my car was apparently parked facing the wrong direction. My landlord was given a warning for having a lawnmower visible from the street, lol. So even in neighboring counties it’s different.
Where I’m living now, it’s not as strict on private property, but there are still lots of regulations. I could see a house like this being flagged where I live if someone reported it.
