The SLAR Governmental Affairs department regularly surveys St. Louis County municipalities in order to maintain up-to-date information on sign and inspection ordinances in the area. We compile the data we receive into a Municipal Code Summary. Click here for a printable version of the St. Louis County Municipal Code Summary. This summary is not an official document and municipal codes may have changed since the last summary was published. We recommend checking with the municipality if you have any questions regarding a specific ordinance.
