so, what does it mean to advertise a non-smoking building?
i understand that it may not necessarily mean that the building is completely smoke-free, at this exact time. but, what it should mean is that the landlord is broadcasting that it will aggressively seek to remove smoking tenants when they are disturbing non-smoking tenants.
the point of difficulty seems to be in getting property managers to deal with it. this is no doubt in some way a function of laziness, but it's no doubt a mental block, as well - even if these people don't smoke, because a lot of them are older, and this city is stuck in the past, they have astoundingly out-of-date attitudes towards smoking. they don't think it's a big deal, and they're going to look at the non-smokers as the troublemakers.
but, when you are advertising a non-smoking building, what you should be broadcasting is the opposite: that you will not take the side of smokers, and that you will act aggressively to stand up for the rights of non-smokers.
otherwise, it's just false advertising.
