    Methane needs 5-16PPM [PDF] to be detectable with human smell. Atmospheric Methane is at about 2ppm. So the vast majority of people would not notice a difference.

      methane doesn’t have an odor, you linked to the data sheet of trichlorofluoromethane, a completely different molecule

      The gas in your house is artificially made stinky so that people would notice leaks and blow their house up, which happened a lot back when the stinky chemicals weren’t added and it was odorless
