Thanks for the responses guys. I guess the section of the code I was reading was with respect to the drywall itself (or perhaps just stucco, which I think often gets confused with stippled ceilings. That’s been my experience talking with friends and family at least, stucco and stipple seem interchangeable to the average person!)
There are the beginnings of mold growth on the bathroom stippled ceiling, which is where my current cleaning concerns come in. My girlfriends place also has stippled ceilings in the bathroom and we spray the mold, but give it a month or two and it’s back. I’ve read that once the mold is there, spraying it isn’t enough since the spores still survive and cause allergies.
I have to admit I was a bit surprised to hear that the code wouldn’t cover this sort of thing, although the devil’s advocate in me can easily see the argument either way. I can certainly understand why it might be considered a non-code related ceiling finish to a code-related ceiling material (the drywall) as dcook1 replied, but I would have thought that a “waterproof” finish of a shower area should include the ceiling as well.
Thanks again guys, sorry for the rant
