Yes, it’d be nice if contractors kept up to date on the progress of the various building codes. They don’t. There are a lot of people who asked about the building codes in the 1970s and were told (right or wrong) what they were. So they went ahead and learned their trade, build their homes, and chose watching a DVD or spending time with their kids over watching city council do battle over asbestos insulation. Now all of a sudden they’re told that their work isn’t up to code any more. Some waiting and gnashing of teeth is to be expected. What’s needed is less "boy, aren’t I smarter than them" snideness and more "Hey, here’s what’s up."
