City Government Structure

An inside look explaining the  structure of St. Louis City government and how it works.

The governmental structure of the City of St. Louis is unusual in the United States. Since 1876, St. Louis has been an independent city, meaning it is not part of any county. St. Louis operates as both a city and a county. St. Louis is the only city in Missouri which operates its own "county" offices. St. Louis is a home rule city, but it is not a home rule county, thus county functions and offices are subject to state restrictions on county governments. 

St. Louis County is an entirely separate governmental entity surrounding the City of St. Louis.
