Find How a Property is Zoned and Requirements for Each Zone District

St. Louis County is divided into various land use zone districts. In each zone district there are regulations for permitted uses of land and the placement of all structures. A zoning index map of the county will help you find the correct zoning map for your property.

To find the appropriate zone district requirement sheet for your property, see the process tab below and follow the instructions. If you are unsure as to who administers the zoning for your property, consult the Administration of Zoning Map located in the tab below.

Zone district information sheets have been updated with the adoption of Zoning Ordinance 62.
