Stair Stringers Connecting to Double Joist

[snydesc]

I am in the process of building a 2 story garage and I designed the stairs to connect to the joists in the picture above.  There is a double joist hanger connecting the one set of double joists to to the double joists that run parallel to the stairs (circled in blue).  When I attach the stair stringer on this side it will hit the joist hanger.  How do I install the stringer without hitting the joist hanger?  Do I route the back of the ledger board and fit it over the joist hanger so the ledger board sits flush against the joist?  Do I offset the stringer the width of the joist hanger?  Any help would be much appreciated.

I usually offset the stringers inboard 1.5" and run a 2x4 on the outside of the stringer, flush to the bottom.
I do something a little atypical with my rough stairs. I glue and nail 3/4 plywood as the rough treads and risers, these are cut to fit flush on the stringers, are permanent and accounted for in laying out the stringers. The 2x4 offset strengthens the stringer and allows sheet goods to slide down below the stairs, no need to notch the wall coverings. The finish treads and risers are glued and screwed from below wherever possible, hiding most fasteners. Don't forget to sheetrock the underside of the stairs for fire protection, keep that egress useable in an emergency as long as possible. If there is living above the stairs cannot dump you into the garage, where the fire probably is, they must carry you outside. I've wandered deep into what ifs so I'll keep the theme. Remember in that event there will be 2 linebacker sized guys running down the stairs carrying someone. The other consideration with stairs is notice how many family photos have the entire family lined up on the stairs, they can see serious loads. I like to frame a closet or doorway under the stair when possible to support that upper end on post and header.
