I have always viewed the stringer / deck connection as a weak link when building taller deck stairs. Im interested in finding out how other contractors hang their stringers.
I use a piece of 3/4 pt ply. It gets fastened to the back of the double flush beam with 3 1/4 nails and 4 headlocks. The stringer gets fastened to the ply with 4, 3 /2 nails per stringer, through the back.

How do you keep the ply from rotting?

I build a wall so to speak, that my stairs lean against. The weight isn't all on the deck side. It's also carried by the landing at the bottom.

There is a few ways of doing it. one is you cut your stringer adding an extra tread, make a notch and go under it fastening to the joist. Using 2x12 stringer you maintaining more than 5" min requirement between the tread and the bottom of the stringer.

Another way is to add blocking to the joist or extend a 4x4 post and add 2x to provide solid back support for the stringer.

Here is something to give you an idea.

As a quick fyi, can only do this if you're deck framing is less than 2x10s...the inside mount I'm talking about

Im going to give this technique a try with the next deck. Most of the decks you see around here the stringers are held in place with pieces of vertical 5/4 x 6 decking.

Anyone use Simpson LSC adjustable stair stringer connector?

This because inspectors ban me use 3/4 plywood and use metal strips. Virtually do not know other way. If would this be banned to I would give up at stairs.

The inspector prohibits the use of 3/4 ply and metal straps. And if he decided to fail this, I'd give up on building stairs, because I don't know another way.
