Dear all, 

we have a project aiming a certification under the Retail NC v4. There will be a restaurant on the rooftop terrace of our building. According to the local norms, it is not forbidden to smoke on a terrace and within the outside area of a restaurant, our client is willing to prohibit smoking within the LEED required distance but not willing to prohibit smoking within the restaurant area. In general, I have a few questions: 

- Is smoking on a rooftop terrace, if the distance to openings is compliant with the LEED requirements, prohibited or not?

- If it is not prohibited, should there be a designated smoking area or only the distance rule applies?

- If smoking is allowed, are there some other special requirements that we must take into consideration? 

I would very much appreciate it, if you share your experience. Thank you.
