Trent Tarter Posted May 20, 2015 Report Share Posted May 20, 2015 Wanting some clarification that anchor bolts are required on all foundation sill plates and knee walls, specifically the foundation knee walls for floor structure support. New home I inspected yesterday had no anchor bolts on foundation knee wall footings in crawlspace. Appeared that the used nails to secure sill plate to footings.

Jim Katen Posted May 20, 2015 Report Share Posted May 20, 2015 Here's the applicable section of the WA code: Download Attachment: Foundation Anchorage WA2009.pdf 26.41 KB It seems to me that the code is saying you need the bolts. That said, I don't know what the bolts are going to do that the PA fasteners won't do in this particular application. Uplift isn't an issue here. There's not much in the way of a connection between the knee wall and the joists, and the wall isn't sheathed, so it doesn't need to resist lateral forces.
