Sawhorse
Given:
I am the authority having jurisdiction.
I have a Type 3B exterior bearing wall that is 2 hour fire-rated and consists of noncombustible materials and fire-retardant-treated wood framing - except for the plywood subfloor.
Question:
Does the 3/4" floor sheathing highlighted in orange (see attachment or use your imagination) also need to be fire-retardant-treated? Or is it permissible to be regular plywood?
Thank you
