There are apartment buildings that ban smoking throughout the building. It's unfortunate that there are those that don't.

I work in an office complex that prohibits smoking throughout all buildings and nearby, but provides a "smoking area" outside; unfortunately that area is right next to the path between my building and the next, so the smoke and smell inundates the path. I have to wonder how much they'd lose by simply banning it anywhere on the grounds. It's not like smokers are a protected class, or that there are any requirements to provide for them.
