I've been trying to find industry standards/norms regarding bearing wall elevation tolerances. In other words, how similar should you expect the elevation of the top plates on the concrete walls (as well as the top plates on any bearing stud walls) to be?
I'm not referring to the pour of the foundation walls, rather the carpentry work of leveling the top plates on those poured walls(if required) and constructing equal height bearing stud-walls. Effectively the surfaces that the floor joists will rest upon.
I've found sub-floor flatness/slope standards in the Residential Construction Performance Guidelines (which are certainly directly related) but I can't find anything along the lines of: "All top plates, forming the basis for the sub-floor, should be within 1/2" of the highest point over any 20' radius." or "abutting top plates should have a transition height differential of no more than 1/4"." And the examples above are pulled out of thin air, pay them no attention.
That type of thing
I'm interested in both professional opinions and industry accepted standards/code. I honestly don't know if I'm being overly critical. I'll share my numbers later but don't want to shade responses up front.
Thanks guys!
