So today after a few weeks I went to go follow up on the progress of my tract home being built. Things are coming along well. One concern though I have that I found random was that there's about 60 or so feet of random non-OSB sheathed walls around the house. They just put some plastic coroplast feeling type of plastic against the framing and nailed Dupont Tyvek to it. I find this weird.
Wouldn't the whole house have the OSB? I have attached some pictures below. If this is a California code thing or something please let me now but its a little concerning. One of the areas they put the plastic was behind our heads in the master bedroom. Someone can just literally punch a hole through the house if they wanted to. I really hope they don't do this to save a couple hundred bucks on some wood. I would have paid the damn difference.
Any advice or if I should be concerned please let me know. I found this in four spots on the house listed below:
Master bedroom, directly behind my headrest of the bed 8 feet
Outside wall of entire garage - 20 or so feet
about 6 feet right behind the 3.0 ton AC connections near our rear sliding door.
about 8 feet in my spare bedroom external wall
The rest of the house seems sturdy with strong plywood or OSB on the 2x6 studs but this seems like a security issue as well as a strength issue.
