OK I am rebuilding my deck. The code says this. Joist size 2x6 Joist spacing 16" OC joist Span 9'5" Joist size 2x6 Joist Spacing 24"OC Joist Span 7'10" OK Spacing is the distance between the center of each joist what is the span? This is going to be attached to the house via 2x8 ledger board attached to solid concrete. I need the deck to be 12' from house on one part and 16' from the house on another. So if I used 16" oc spacing I could go out from the house 9" and set footings (Precast concrete supports) Here is what it needs to look like.
