The objective of zoning codes is to promote the safety, health, and general welfare of citizens. The earliest zoning ordinance on record in the USA was enacted in 1913 in New York City to regulate the height, size, and layout of buildings. The motion made by the president of Manhattan Borough stressed the need to limit building heights to stop the congested living and street conditions. In 1916, a more comprehensive ordinance was adopted to control the density and uses of land. During the 1920s, zoning codes were enacted in all regions of the nation.
