Our project is in a very urban environment, and the front door opens to a public city sidewalk and then public road (no landscape, parking lot, etc). No smoking is permitted within the building. Is the client required by USGBC to ban smoking within 25ft of the entrance - or is public property exempt from the 25ft rule? I'm not sure that it is possible to prohibit the public from smoking in their cars as they drive by the space or hustle by on the sidewalk on their walk home from work!
