legislative regulations by which a municipal government seeks to control the use of buildings and land within the municipality. It has become, in the United States, a widespread method of controlling urban and suburban construction and removing congestion and other defects of existing plans. Great Britain, Germany, and Sweden preceded the United States in zoning for the purpose of controlling building in new areas adjoining cities, but now use comprehensive plans. The zoning resolution adopted by New York City in 1916 was the first in the United States and has profoundly affected New York architecture, while the standard it set has been followed by other cities. By this law (since superseded) New York City was divided into use districts, area districts, and height districts. Use districts are of four classes: residential, business, retail, and unrestricted. The height and area limitations serve to insure light and air for the occupants of city buildings. Municipal zoning was upheld by the Supreme Court in 1926; its decision, which concerned the ordinance adopted by Euclid, Ohio, established zoning as a legitimate use of a municipality's police power to protect the public welfare. In the United States the state legislatures hold the power to authorize zoning, under which the separate municipalities enact their own zoning ordinances, which are typically closely integrated with a city planningcity planning,
process of planning for the improvement of urban centers in order to provide healthy and safe living conditions, efficient transport and communication, adequate public facilities, and aesthetic surroundings.

The U.S. Supreme Court has ruled against such zoning in directing that public housing in Chicago be spread beyond the city limits. Some state courts have gone further, declaring that developing communities have an obligation to accommodate their fair share of a region's needs for modest homes and apartments.
