I am redoing my kitchen and wanted to move my gas range to the wall next to where the line exists (just extend the flexible pipe). I've had several contractors come out, none thought it was a big deal, and then the last one told me that in order for it to pass inspection we would have to do a gas inspection on the entire building. I live in a prewar on the 5th floor and he said, it would most likely be a huge problem for the entire building costing tens of thousands of dollars. Does anyone know anything about this? How do people deal with this in NYC? Do they just not register it with the DOB?
