According to the following, a deck using 2x10" joists, spaced 12" apart, can have a span (distance from attachment to house to row of footings) of 16'.
I just had a contractor bid the job for my new deck, which I want to be 15' deep. He said because the footers will be ~14.5' from the edge of the house (and plans to use the aforementioned joists/construction), he plans to only put one row of footers. While this technically passes the above rule (code? rule of thumb?), is this shoddy work? He said an additional row of footers would cost extra, and definitely wasn't necessary. I wanted to get the community's opinion. Is the 16' number "built to last", or "absolute maximum before it becomes a safety hazard"?
