Not where I really want to be
This is why I love framing inspections.

Yes, or an engineered tall wall design from the engineered lumber manufacturer.

Looks like 18 ft Height 2X6 studs 16 inches OC assuming you are less than 100 MPH windspeed

Yes it is permitted under Table R602.3.1.

R602.3.1 Stud size, height and spacing.

The size, height and spacing of studs shall be in accordance with Table R602.3.(5).

Exceptions:

1. Utility grade studs shall not be spaced more than 16 inches (406 mm) on center, shall not support more than a roof and ceiling, and shall not exceed 8 feet (2438 mm) in height for exterior walls and load-bearing walls or 10 feet (3048 mm) for interior nonload-bearing walls.

2. Studs more than 10 feet (3048 mm) in height which are in accordance with Table R602.3.1.
 
mtlogcabin, look at footnote b in Table R602.3.1. It's pretty limited. Trib floor or roof dimension of 6 feet and max. overall floor or roof span supported is 12 feet.
 
Is any of the plywood part of a shear panel?

When do the anchor bolts get installed?

Is the wall with the I-joist in the middle hinged on purpose?

The solid beam on the left looks like engineered I-Joist rim material. I wouldn't expect to see that as a beam. The I-Joist is used wrong (in a bearing condition) at the hinged wall.

I try to wait for the electrician to finish before I do a framing inspection. Plumbing and mechanical too.

And yes, a stamp is required. It's a two story building.

The second floor laundry room joists at the left look like TJI's. At the edge of the floor, exposed to view, is a piece of solid 2X lumber. My understanding the solid lumber will shrink, and the TJI's won't. Engineered floor joist systems should (in NY) be accompanied by the design & installation instructions.(which will not have solid lumber components)

I saw that after I posted my comment about the snow load. It is hard to tell what span the roof is, might be within the tributary dimensions for a roof. Maybe JAR can give us some more info.
 
We typically see engineering for tall walls like this. How do you guys feel about the orientation of the plywood? Don't think it is wrong necessarily, just always see it vertical here.

If there is shear wall required, the plywood edges must be blocked and nailed.
 
I assumed that was an lvl at the laundry rim. There is no hinge, not that it's right, that is a row of blocking midway on the tall wall. The rafters sitting on a raising plate are not well tied, the hip area is also untied.
 
DRP,

That could be an LVL. The hinge is in the wall with no windows. I can't see what's up with the rafters.

Now that you mention it :D

The rafters appear to be on a flatways 2x~10 plate that is nailed atop the cj's with no rim or perimeter blocking. It's sort of similar to a situation we were discussing a few months ago.

Ya that was Jeff's shed. Do you suppose that this is Jeff's house?

It appears that when the rafters are framed in that manner the shear transfer from the rafters to the c.j.'s and the top plates is compromised as they are not 'locked' together as efficiently. Do the rafters intersect the c.j.'s farther out? It's be interesting to see the outside of the framing in the same area.
 
Can't be any shear walls. The one to the left of the windows clearly exceeds any height to width ratio I know of.
 
The shear transfer from the roof diaphragm relies on a frieze block and not the connection between the rafter and the ceiling joist. As it is, the rafter must be bearing on the flat 2x. What happened with the frieze block is not visible and there are no A-35s in the picture. So the force transfer is unknown.

This being a hip roof may negate the need for a rafter tie but the whole building may need it here and there.

We should find somebody that's been there and ask them.
