In a city where it’s already illegal to smoke in restaurants, bars, parks, and beaches, smokers could always retreat to their apartments to light up. Those days may be over. Condo and Co-op boards in Manhattan that want to ban smoking in their buildings may soon have the legal means to do so, because both Mayor Bloomberg and the Real Estate Board of New York (REBNY) proposed new policies this week that would facilitate the creation of smoking bans in Manhattan apartment buildings. Many condominium and co-op boards are increasingly considering banning smoking, and not just for health reasons: in the past, boards worried that smoking restrictions would limit the amount of potential buyers, but now the national rate for smokers is roughly 20%. With non-smokers significantly outnumbering smokers, many boards believe that banning smoking in their buildings will actually become a marketing advantage that helps attract potential buyers.
