Unless your state licensing law prohibits you from citing code, I fail to see what problems citing code could cause.

Now, *citing the wrong code* could embarrass you, but no more than calling something 'unsafe' when it is not 'unsafe'.

Using mamby-pamby wording to avoid citing code just makes you look silly and less knowledgeable. If you know it is not code complaint, say so, and give the code.

Whether or not the builder fixes it *IS NOT* going to be dependent on whether or not you cite code, ... BUT ... you will have a better chance for them to address it if you provide documentation to back up what you say.
