Looking to add a small 4’x4’ bump out and then stairs (coming back towards the house). Deck is 15.5’x15.5’. 2 beams made up of 2 2×10’s with a span of 6 ¾’ between 3 6×6 posts. Joists are 2×8 with a span of 7 ¼’. My question is, I know I need to add posts on the far side of the platform (red dots) but do I need to add two more posts at the yellow dots or can I tie into the Rim joist? Thank you!
Prescriptive codes don't address the connection at less common angles, so base the connection off more typical ones using bolts, structural screws, blocking, and steel tension ties.
