Framing 2x6 Exterior Corners
Framing 2x6 Exterior Corners
(OP)
I've been struggling with the best way to frame ext. corners on 2x6 walls so I looked through a number of my framing texts and online and put together a small matrix with a number of methods.

I do a lot of designs with hardiplank siding so good backing for the trim and siding is important to me. Up until now I've been specifying Detail 2 a lot, but now I'm looking at Detail 5 and it seems to offer the same advantages and more. Any thoughts?

Seems like all of those options require a lot of extra nailing, time, and lumber than the optimum.

So, #1, #3, or a slightly modified #8.

Google on "California Corner" and you will get hits, including videos, that appear to indicate that it still is considered an excellent detail.

I also don't like Option #1 (california corner) for siding because on the one side there is not much to nail your siding or trim boards into. That is which I'm thinking Option 5# would be a better alternative, giving good insulation into the corner, easy access for electrician, nailing surfaces for both gyp. board and siding and trim.

You need to think in three dimensions here to solve the problem.
Remember that in #9, any HD class of hold down will only occupy the bottom foot or so of the corner. There us still room for the corner nailer above that - usually another stud nailed to the other three studs or a 6x6. The sheetrock will span that distance OK.

You are putting the cart before the horse here. Structures do not fail due to a lack of insulation. They fail with inadequate or insufficient hold downs. The energy code does not trump safety.
That being said, I can see the conflict however with what you say here. I think one solution would be to compromise and use an exterior strap rather than an internal rod type hold down if the capacity was sufficient, or choose another location for the shear wall, if one was available. Sometimes there is no other location though.
The fact remains that corner placement of hold downs increases the leverage to resist uplift, and decreases the uplift force that is required to be resisted. The use of the corner location can also decrease the overall number of hold downs in the structure as it can be used to resist uplift in two directions, not just one.

The greatest trick that bond stress ever pulled was convincing the world it didn't exist.
