How can I attach a 2x to a deck joist to give more room for stair stringer?

Question

I am attaching stairs to a deck coming perpendicular off of the joist. To attach the stair stringers to the deck I need to add a 2x6 below the joist so the stair stringer hanger can attach to it. I had seen these at home depot and wondered if I could attach the 2x6 to the 2x10 joist with a few of them, but they were not load rated.

What is the proper way to do this. I do not have two posts directly behind the stairs that I can attach it too.

My other option is to do the deck stairs flush with the top, but then I am not sure how I'll make the railings going down the stairs.

Answer 1

I attach the 2x6 right to the face of the 2x10 joist. With an 8" rise you will have 2.5" to attach it too. I use alot of nails and a few ledgerlock lags. I also always double the outside joist. I never had an inspector question it. If the bottom your steps are firmly attached by burying posts the stairs can not fall down.
