Questions

Which codes does Illinois use?

Illinois is covered by 14 books in Ichi, on the 2021 cycle: ILAC, ILECC, ILPC, ILSEC, IBC, IEBC, and 8 more. The full list is above.

Does Ichi include Illinois's local amendments?

This group currently carries the adopted model and state codes. If Illinois has adopted local amendments we don't yet have, email connect@ichiplan.com — new books are typically added within a week.

How current is this code group?

Code groups are maintained in the Ichi platform and this page reflects that library directly. New books, editions and amendments are added on an ongoing basis, and jurisdictions can be added on request.

Can I read the full code text here?

This page lists coverage — which books, which edition, which amendments. The code text itself lives inside Ichi, where it's delivered under our licensing agreements with the ICC and other publishers, and where every answer links to the exact section it came from.
