This was forwarded to me by a colleague off forum. Looks like paragraph 1 is where it is required. And paragraph IV is where it exempts dimensional lumber greater than 2 x 10. Looks like it came in with the 2012 IRC. And since paragraph I specifically calls out NFPA13D my original question has been answered.

On the one hand I can't argue that his concern isn't valid. On the other hand I'd like to see where that is required by his code as it is otherwise an arbitrary and capricious demand on his part that harms the owner financially relative to the AHJs whim. My third hand carries the same question I have about attics and garages. If you don't want people to fall through the roof don't have them climb on the roof. If you're concerned about lives have your legislature pass a residential ordinance and put the sprinklers in.
