UN-treated bottom plate
UN-treated bottom plate
(OP)
I have been asked to look at a remodel project that includes wood framed load bearing walls (IBC 2012). The walls have been located and constructed over the existing vinyl tile that covers a conventional slab on ground foundation. The builder did not use pressure treated bottom plates and insists that they are not required since the wood is not in direct contact with the concrete. I have seen many cases where older construction has a sheet metal termite shield between suspended concrete framing beams and wood (untreated) floor framing. Granted, it was pre ICC construction, but my question is:
If the wood bottom plates are not directly in contact with the concrete foundation, can I state that the lack of a pressure treated bottom plate DOES NOT meet code.
Thanks in advance to the forum for your views on the subject.

The vinyl floor should effectively preclude the moisture issue and would function in a manner similar to the use of a PEVB or building paper...

"2304.11.2.4 Sleepers and sills.
Sleepers and sills on a concrete or masonry slab that is in direct contact with earth shall be of naturally durable or preservative-treated wood."
It only states that if the slab is in direct contact with the earth, not whether or not the sleepers and sills are in direct contact with the slab. You might have to go to the AHJ for what they want on this.
