A bearing wall or a shear wall can only be offset the joist thickness, 9-1/4” to the face, in your case; Fig. 67, as it says--- check locally with your Building Department; http://docs.google.com/viewer?a=v&q=...Ayb-Iq_X-tT_ew


Anything more needs to be approved by them.

the maximum for 2x12 is 4 feet and you need 2 parts in to one part out so i would definitely not go over 3 feet and the two end need to be doubled if you were out 3 feet you would have six feet inside the building glued and nailed to the other joists

2 to 1 only works to a certain point. You need to have an engineer look at it. Best couple hundred bucks youll spend. Lots of things affect a cantilever. The roof, what the room purpose is, floor covering, one story or two. Ive framed for a while and I dont even try and guess this stuff. Long term problems arnt worth it.

Im always a bit careful in here. Dont want anyone canting a floor four ft then throwing a 30 ft ridge up that bears on that cant with a door out to there deck that's 20 X20 hanging of that cant. Structural stuff and DIY sometimes are really scary. Ive worked on some scary fixes.

I have that one also (232), dated 2006. It has been replaced with the 2009; (first one listed); http://www.google.com/search?client=...=Google+Search
Which does not cover cantilevers (or maybe I missed it) which is why I quoted the most current IRC 2009, depends on which Code the OP is under….. Check with your local B.D, as mentioned.
