- A tool a community may utilize to regulate how land is used in different areas or districts of the community and establishes locations for different type of development. The zoning ordinance consists of 2 parts, a text and a map of the zoning districts. The text contains information on building height, area, setback, density and other standards. The zoning map delineates the boundaries of specific districts or zones. It divides all land within a municipality into zones and creates regulations that apply to specific zones. Zoning should account for all types of land uses and housing types.
