Let's make sure we're clear on this. I live in Morton Grove, Il. The electrical code for Morton Grove is the Chicago Electric code. It's the Chicago electric code that is online. Amendments that apply to Morton Grove are on the Morton Grove website.
Just Electric. Morton Grove codes for plumbing, HVAC, etc aren't available online. They refer you other code books, but do have amendments that apply to Morton Grove.
This is the website for Chicago codes. You have to hit "more at the bottom to get the electric chapters. Division 27. It ain't as pretty as a book. And I have no idea how it compares to NEC. Do me a favor will you? If you actually read through the codes and find a part that says "Refer to NEC 2011," keep it yourself, ok?
