I'm sure it's not a big job to put the GFCI in.
I understand the confusion here, but the AHJ does call the shot. I my self am not an inspector but am licensed and certified with 2 out of 3 exams from the IAEI. I hope to take the exam on 1 and 2 family dwellings soon. It will certify me as an inspector, but I'll be doing it for my own satisfaction and concern for the trade.
Have a great day
