I always recommend gfci's. To me this is a safety upgrade, not a defect, if they were not required at the time of construction or remodel. I like to distinguish between the two in my reports. Gfci's, like I said earlier, was just the first thing that came to mind when I first posted. There are many more situations that I will run across in my career. That is why I was looking for a reference on code and the changes through the years to help me make that distinction.
