Wow, well that's one helpful chart for the NEC!
Even on a local jurisdiction website what are you supposed to look for specifically? Building codes will just reference NFPA 72, but not the year.
So would a logical guess be if the latest building code is lets say 2008 in an area, that the latest NFPA would be 2007, since 2008 code can't reference 2011 code? Or is this not true.
If the building code references another code without giving the year or additon of that code, then case law says the edition of the referenced code will be the one that was current at the time that the building code was adopted.
