Zoning in the United States is a way that cities and towns decide what can be built where. It's like drawing a big map with different colors for different parts of a town.
Each color means something different, like orange for stores, red for houses, and green for parks. These colors show people where they are allowed to build buildings, put up signs, and do other things.
Zoning helps keep things organized and makes sure that people are building in places where it makes sense. For example, you wouldn't want a big, noisy factory right next to a quiet, peaceful neighborhood.
Zoning also helps make sure that all areas of a town or city have access to things they need, like stores and parks. It's like a big puzzle that makes a town work well for everyone who lives there.
