Does anyone know the history - reasoning - purpose behind IRC section R502.6.1 - Opposite floor joist over interior supports lapped 3"? In this case there are 2x8 floor joist spanning 8' to 9' butt together over a double LVL beam and NO wall above it. A home inspector is saying telling a contractor it doesn't meet code. Granted it doesn't, but I don't see where its critical. There is adequate end bearing, and 3" isn't long enough of a lap to consider it a continuous member. LTB won't be a factor because continuous solid blocking is installed. I plan to show have a 2x4 scabbed across the butt joint, but really don't see the need for it. I've ran across this same issue a few years ago when an insurance company denied a claim after a wash machine ran over, and the floor sheathing buckled claiming it wasn't built to code. Appears to be an in the IRC because it's always been there, and nobody has a motivation to remove it. Any thoughts someone is willing to share will be appreciated. Thanks,
