not talking about a specific wall.. i just see alot of framing going up where the rim joist is mounted flush with the sheathing
Around here (Ontario) it is RARE to see anyone sheet the rim. I sheet my walkouts through which is more then a lot of guys even.
We are honestly usually so tight on material that the extra 5 sheets it'd take for the house wouldn't be possible.
Correct me if I am wrong, but most of the west coast US guys need to do for sheer value.

Hmm guess i'll have to have a chat with my engineer i dont see the northwest having much difference in shear specs than the south

I do it for the same reason Warren does. Along the shore, if the plywood doesn't span across the box at least 1' each way, straps are required.
That was several years ago though. Straps may be required no matter what now. :furious:

I've worked in Cali my whole life and I've never seen an exposed rim board. It's for sheer and to tie floors together. 'Course, this is earthquake country.

we always sheath the ribbon here, the method varies based on wall height, if the walls are 8' we chew up the scraps and use them on the ribbon. for 9' and 10 ' walls we put 2 sheets on the wall then fill in the rest up to the bottom plate of the next floor walls to lock it together
i know a few local framers that dont sheat the outside face of the end stud on exterior walls, the plates get cut to the exact lenght of the wall so they dont have to put a 5 3/4" strip on each end

We start at the sill and sheath up form there horizontally with cdx.
Joe, I thought you had a special crew come in and install the sheathing..
I've done both and never had an engineer or city inspector bat an eye or even ask about it. I've been experimenting lately.... normally I would sheathe the 1st floor walls in the air (slab on grade) before starting the second floor deck.
On my last build we built the second floor deck sheathed the floor and then ran the exterior wall sheathing over the rim joist with a 1' filler in the middle of the wall.
I found the latter to be a little more efficient as the helper was able to "walk through walls" with joists and whatnot. Our shear value also increased, as the sheathing connected the 1st floor walls with the second floor deck.

I don't do much framing anymore but when I did I always ran the sheathing down to within a 1/4" of the sill plate.
On 2 storeys I always ran the sheathing to bridge the rim and tie into the first floor walls.
it only takes a little extra effort and to my way of thinking it helps stiffen everything.
I have seen it the other way more often than not. I also see the end studs when walls are tied together. That is another pet peeve of mine!

On new houses. Additions I sheath myself. Either way, no matter who does it, the the sheathing is the same way as I said above.

I'm not a framer but I'm sure I've seen it done both ways plenty here.

why do you wait until the wall is strait?
