I am building a 2 story deck on the rear of my house. The deck is supported by a 2-2x12 girder through bolted to a 6x6 post set on footing at grade and a 2x12 ledger lagged to the house framing. My question is, how far can i cantilever the girder off the posts. I am in the need of about five additional feet from the post. Most codes state for every foot over bearing point you must have 2 feet back. The joists are 2 x12, 16" O.C. All framing material is #2 or better AC2 (gt). A link to a span or cantilever chart would be great or if you know from experience thats great too.

thanks

Your using the right wood, rule of thumb and weight distribution in heights should always be over compensated, for what ever I have cantilevering I have two in return, so how does that work?
I have two feet hanging over, I have 4 foot from the edge of the girder back, using Simpson straps or hangers attached. I've been a Bay Area Framer for 35 years and over building gives a person piece of mind, especially in height conditions. Their is more to to securing an cantilever but here is my two cents to start.
