One technical issue I have seen come up very frequently with architects working in Chicago is that they often refer to a version of the building code that does not include the most recent code amendments. It is actually a very easy mistake to make. We’ve covered the content of one of the most important new amendments here.
This most likely happens because the majority of people access the building code directly from a link that they've bookmarked in their web browser. The problem with this is that ICC (where the building code is hosted) creates a new URL with each new passage of amendments to the code. Until recently, even the building department’s web page linked to an outdated version of the building code because of this.
