How should I attach a deck on the corner of my house?
I'm not a fan of ledgers, ever.  

You can place a beam 3ft out from the house, cantilever the joists over the beam (secure them to the beam with hurricane ties) and wrap the joist ends with a rim joist.  Make the structure within 3/4" of the house.  

Do a double rim joist in front of the doorwall side.
