I have some contractors who just put in a new load bearing wall in a second story dormer. In this load bearing wall they have studs that have been cut all the way through bearing load (note they are not notched out or over bored; it literally looks like they took a circular saw, cut through the bottom of the studs and left the pieces sitting on top of the bottom pieces. Each of these cut studs has sistered 2x4s around the bottom bit where it has been cut (one on each side). Is this against code? It looks unsafe and these guys have cut many corners and I think they left it like this to avoid paying for new studs.
