Structural supports required in closet walls?
I’m building a new home. My builder didn’t put studs or headers in the walls to support the ends of the shelves, nailing the supports directly into sheetrock. And he refuses to correct it. Of course, this won’t hold up anything of substance. Is there a building code in the US that requires structural members (studs or headers) in the walls, or other means to adequately support the weight to be placed on these shelves? I see this as a safety issue.
