In real estate and land use regulation, zoning is the division of a city or county into designated areas or districts by legislative action. These regulations specify the types of uses that are permitted for real property within each area.

Zoning ordinances typically govern matters such as residential, commercial, and industrial uses, as well as building height, density, setbacks, and other development standards. The purpose of zoning is to promote orderly growth, protect property values, and safeguard public health, safety, and welfare.
