Ironically I came across this article while searching to see if carbon monoxide detectors/alarms are legally required for Salt Lake City residents. My daughter has a gas furnace unit in a closet in her living room. I asked her if she has a detector, and she says the landlord provides one, but she thinks it's just a smoke detector. Does anyone know if it's required by law for the landlord to install a carbon monoxide detector/alarm in her apartment? Thanks for any info.
