A small addition to a 100 year old seasonal "camp" is wanted to be framed in 2x4 so window and door details exactly match what is seen in existing. We can meet all structural needs with the 2x4 walls, and pass ResCheck by using sprayfoam in wall cavities, and one of the Huber ZipR sheathings.
I cannot find a hook in the codes which would mandate 2x6 framing and not permit 2x4 framing. Is there such language?
