Well 20 feet from entrances. In most places that means you have to be curbed by the street.A lot of people in my building smoke, oddly. There were complaints sent out that they need to be by the street or on the opposite side of the street because it could be smelled in their children's room (5th floor). I think people just love to hate on smokers. Also, no smoking in our common backyard. Fucking fascists.
