Is it legal for a home/condo owner to do any electric work in Chicago?
If I recall, Chicago requires conduit wiring methods.  

Thing about conduit is, about 3/4 of the actual work is planning conduit design, planning fill (in both aspects), cubic-inching the junction boxes, fitting the conduit and boxes, working out run lengths, and getting pull strings into the conduit. None of that is actually wiring, now is it? 

You just need an electrician who will work with you and not have a Rumplestiltskin fit because he didn't get to do the whole job.
