Discover the Chicago Code

The laws of Chicago, for non-lawyers.

Chicago Decoded provides the Chicago Code on one friendly website. Inline definitions, cross-references, bulk downloads, a modern API, and all of the niceties of modern website design. It’s like the expensive software lawyers use, but free and wonderful.

This is a public beta test of Chicago Decoded, which is to say that everything is under development. Things are funny looking, broken, and generally unreliable right now.

This site is powered by The State Decoded.

Inline Definitions

Throughout the Chicago Code, very specific legal definitions are provided for terminology both specialized and mundane. If you don’t know which words have special definitions, and what those definitions are, then you can’t understand what a law really means. Chicago Decoded solves this problem neatly, by identifying every definition in the Chicago Code and providing a pop-up definition every time that a defined word appears.

Bulk Downloads

Chicago Decoded isn’t just a pretty website—you can take the laws with you, too. On our downloads page you can get copies of all of the laws of Chicago in any format that you like, to do whatever you like with. They’re available in formats meant for you to read and in formats meant for software to read, too. If you’re a software developer, you’ll love our API!
