Another deck question:
I’m planning to frame a deck with 2×6 joists attached to a ledger board. Inspection of the house’s crawl space reveals 2×6 floor joists resting on a cripple wall — no rim joist.
My question: if I attach a 2×6 ledger, I’ll only be able to lag screw into the end grain of the joists. If I use a 2×8 ledger, I can also get lag screws into the top plate of the cripple wall. I suppose I could also add blocking between each joist above the cripple wall and screw into those, but the crawl space is tiny and that would be a real pain.
Is it acceptable to lag screw into the end grain of the joists only? Or should I get into the top plate of the cripple wall? There are clearance problems outside (not insurmountable) if I go to the 2×8 ledger. The house is skinned with 3/4″ to 1″ of stucco, if that matters.
Thanks.
