Why? Similar to my blog post in May mentioning the limited design resources currently available to engineers, the IRC itself is also a work in progress when it comes to the prescriptive details included for decks. With my interest in wood decks, I have to admit that this was new information that I was happy to see. As it turns out, this package was the just-published 2015 International Residential Code (IRC).
