Barbara, I think what you are encountering here is that the LEED Online forms are dynamic, i.e., once you choose a submittal path, e.g. "O&M Submittal Path," there are some inputs that show up that you wouldn't see if you were just perusing the form. Once you choose this path, there is a place to upload signage communicating the smoking policy on the exterior of the building.If smoking is completely disallowed inside the building, you simply need owner sign-off to that effect, you don't have to upload additional documentation.
I share Barbara's question, to an extent. I'm working on a school project that prohibits smoking anywhere on the campus. When that submittal path is selected, the required upload is merely for signage evidence and not a policy document, yet the prereq. seems to require the latter (of course in addition to the owner signatures). Can you clarify? Thanks.
