St. Louis County Zoning Maps

Process: 

Persons interested in finding out how a property is zoned and the uses and requirements for that property should first consult the zoning map by following the directions below:

1. Determine Zoning of Property: Determine how a property is zoned. You will first need to know the Township and Range number where the property is located. This can be found by looking at the legal description for the property which can be found on an abstract or tax statement. The letters “Twp” will signify the township number and the letters “Rg” will signify the range number. 

2. Obtain Zoning Map: Once you know the township and range number, click on the zoning  index map and it will bring up the zoning map for your township. So for example Twp 53, Rg 18 you would go to the zoning map legend and click on the township and range box of 53-18. 
   
   

3. Zone District Code: This will bring you to the zoning map page. Next locate the property in question on that map. There will be a zone district code. The zone district code might be one like FAM-1. 

4. Fact Sheets: Next, click on the zone district sheets from the tab below that says FAM-1 or whatever your particular zone district code is. By looking at this sheet, you will be able to find out how many acres are required for a conforming lot and how far a structure must be from adjacent properties, roads, lakes, etc., when building.
