I've recently been trying to find an apartment in NYC. Every apartment has a gas stove. And all of the post-war apartments (and most of the older ones, too) don't have ventilation in the kitchen — at most they'll have a tiny passive vent opening in a corner somewhere, and even that's not guaranteed. The fans over the cooktops, if present, don't connect to outside air but just recirculate the stove exhaust throughout the kitchen. I don't understand how such designs aren't banned by building codes.
