For residential applications, adopting a no-smoking policy in Homeowners Association policies has been a good strategy for reducing ETS transfer between units.
Establish the smoking policies for interior spaces and exterior spaces, including balconies, by working with the building owner. Many municipal codes do not permit smoking in public buildings, so banning smoking (Option 1) may be the only legal option in some cases.
Test all dedicated building exhaust systems including chemical areas, bathroom, shower, kitchen, and parking exhaust systems to confirm proper fan speed, voltage, control sequences, and set points as applicable.
