Zoning, the regulation of the use of real property by local government, restricts a particular territory to residential, commercial, industrial, or other uses. The local governing body considers the character of the property as well as its fitness for particular uses.
Zoning ordinances divide a town, city, village, or county into separate residential, commercial, and industrial districts, thereby preserving the desirable characteristics of each type of setting. These laws generally limit dimensions in each zone.
