Hello, I have a project that does not allow smoking within the building. However, there are small one room kiosks outside the building that allow smoking. These small structures are more than 25 ft from the building. My question is, do I have to designate these rooms as "smoking rooms" and provide pressure differentials, air pressure report, etc, even though these rooms are outside the building? Or do these spaces qualify as "designated smoking area". Thanks for your feedback.
