State of Illinois Smoking Law

I believe that you should be asking thie in IEQp2. The LEED requirement is 25', so I do not think that the state law would qualify for the prerequisite requirements.

I concur with Andrew, EQp2 question and 25ft is required. (See LI #1967)

As for the bare minimum for the signage, i have previously asked this question of the GBCI and here is there response:

"There is no firm answer to this as it depends on the overall context of the exterior smoking policy communication method on the site, but the exact language on the signage, its size, and location(s) are up to the project team (with one caveat for signage locations for v4 projects - see the end of my message below). That being said, the signage throughout the site must somehow effectively communicate the exterior smoking policy to all building occupants and visitors and it must be reasonably visible. For example, a single sign with a crossed-out cigarette and no text at one entrance may not be sufficient and could be misinterpreted as the interior smoking policy, but if such a sign is installed at multiple locations around the building exterior to communicate the extent of the non-smoking area or if there is additional signage to indicate the location of the designated smoking area, this would better communicate the exterior smoking policy. Another example of effective signage language is "Smoking is allowed in designated smoking areas only." Also, reviewers will take into consideration other methods of communicating the exterior smoking policy in conjunction with the signage, such as policing of non-smoking areas by security staff or regular communications with occupants about the smoking policy. If the client wants to do the bare minimum, one approach could be to place a sign only at the designated smoking area saying something such as "Smoking permitted in this area only" and supplementing that with regular communications with the occupants about the site smoking policy.

Also, I just wanted to note that in LEED v4, the prerequisite requirements require signage within 10 feet of all entrances in case this happens to be a v4 project."

hope this helps!
