Garage storage loft build
I've got some unused height at the end of my garage that I'd like to turn into a storage loft. It's about 12' wide, and I'd like to make it 4' deep. The side walls of the garage are unfinished 2x4 framing with exterior sheathing and siding on the outside. There's a double top plate at 10', about where I want the shelf, and the overall height is about 16'. The back wall is a fire rated wall with living space on the other side. (pic 1.) My current plan is to hang four 2"x8"x12' joists on Simpson LUS28 hangers, 16" on center with 2"x8"x6' ledgers screwed into the 2x4 framing with Simpson SDWS 4" #12 structural wood screws. I'll top it with some 3/4" OSB and another half sheet to span the full 12'. (pic 2.) Here are my questions/concerns: The joist near the end wall, I was just going to make it a hanging joist like the others so I didn't have to mess with screwing into the fire rated wall, but then I realized how difficult it would be to secure the joist on that side and be close to the wall. Am I over thinking attaching that joist/ledger to the wall? How would you tackle that? I also don't think I can attach the ledger at the corner where the framing meets the wall as there's only about 1/2" of stud exposed in that corner. Do I just trust the rest of the ledger to hold up, or I could sister a 2x4 to the stud and attach to that? A co-worker of mine suggested that the shelf would be stronger by attaching the joists directly to the top of the 2x4 framing top plate (something like pic 3) but I'm not sure about blocking and stabilizing the joists this way. I'd also need to get longer than 12' boards since the distance is just about 12' face to face on the 2x4s (I'd need about 11' 9" with the ledgers,) but 12'7" give or take directly between the inside of the sheathing. I think my spans calcs are ok for 2x8" at 12', I'd rather not go 10" joists, but I could go 12" OC and five joists... Anything else I'm not considering?
