Hoping you guys can help. I have a house in Denver CO I am trying to sell. One of the problems that is coming back to me is that there is not a range hood over the gas stove. The house is 85+ years old. We did some remodel to the kitchen, new cabinets, tile paint and appliances. The stove is gas but since the house did not come with a hood, we didn't install one. Is it really required by code to have a hood? Anyone know where I can look it up? I've done a couple of searches, but haven't found anything yet.
