I would think "IF" it happened, it would work something like the merger of the regional codes into the IRC a few years back. But then that is just a guess. I am doubting that it will be a cooperative effort due to the animosity between the various organizations. I figure if it happens, it will happen without the groups that oppose it and everyone will be forced into accepting it by legislation, insurance company mandate or whatever. Some will jump on board early while others refuse to the bitter end.
While I don't look forward to change, and unbiased national standard might be preferable to what our realtor controlled state agency forces on us.
