There is a proposal in front of the ICC Code Committee to incorporate a great deal of deck-specific detailing in the 2015 IRC. These details appear to come from the American Wood Council’s DCA6-09, an alternative deck code whose clarity I think most deck builders appreciate.
You can take a look here.
One way to provide input to the code process is to email to: Info@NADRA.org. Your comments must be submitted by January 3, 2013 to be considered. NADRA’s Technical Advisor, PDB contributing editor Glenn Mathewson, will represent NADRA at the ICC’s hearings. Look for more on this code proposal in the January issue of Professional Deck Builder.
