Regulations
With over 90 municipalities in St. Louis County alone, each having their own regulations and procedures governing residential chicken flocks, it can be overwhelming to find out if you can have them and to go through the process to acquire a permit (if needed).
The below information is a helpful tool, but ordinances can change and so we always recommend that you verify with your city before moving forward. If you find that your muncipality has been updated please let us know so we can adjust our information.
If you belong to a neighborhood association, check indentures. If they vary from city ordinance, the more restrictive is to be followed.
