I have a 1.5 year old, 2 story home in Iowa. There have been some pretty large cracks on certain second floor walls, and a lot of doors not latching. Today I noticed the large basement egress windows do not have a typical header, and it looks as if the plates are sagging in the center of the windows. The "header" that is above the window is basically two 2x6s, on the flat, supported by one jack stud on either side. One of the plates above this "header" has a break without any support, other than the "header", below it. I am pretty sure that, on the flat, 2x lumber is not capable of supporting a 5' span of weight bearing wall, such as my windows. There were several issues that the building inspector caught prior to passing, maybe this was overlooked? Can anybody verify this? Thanks.
