Zoning is a tool that most cities use to govern âusesâ (e.g. residential, commercial, or industrial), the size of buildings, and how buildings relate to their surroundings, including other buildings, open spaces, and the street.n the U.S., zoning began as a tool to separate uses from one another, and in particular was used to separate more impactful uses (manufacturing) from more sensitive uses (residential). This type of zoning is largely known as Euclidean Zoning, named after the U.S. Supreme Court Case that legitimized the use of the tool.
