Stud wall brace required or not
We are having a home built and we have 9 to 10 foot ceilings throughout. During framing there were metal strips nailed instead of using the old 2x4 braces. These were done on some of the inside walls but not all of them. It seems that any wall that runs from left to right looking in from the door has these. But no wall running from the front to the back have them. My nephew who works for someone that does additions and remodels said that any wall over 8 foot that is not an outer wall should have these. Is this true. Is it code? Any help would be appreciated.
Thanks...
