Hey Jim, that is really good information. Thanks!

I do not know much about sips. Do the sips have 2x dimensional lumber inside of them on a set center to give them there structural rating? If they do, could you not attach the ledger directly to them? Of course I do not know what kind of rafters you are using for the project.....

I guess, my question is what is the design makeup of the sip?

As far as Scoots cantilever (for a balcony I think) I guess the trouble is connecting the level joists to the sips, then supporting with braces six feet of balcony (balconies in my opinion should be no less than six feet) posts and a roof. Whew!

Scoots, what about recessing the balcony into the house say four feet, and have 6 feet protruding? Of course all of it would be "outside", but there may be a way to get better support. I dunno, interesting topic.
