Spoke with home owner late Friday afternoon. She indicared she was going to go down town on Monday 6-5-2017 to get a mechanical permit. When I was talking to her I let her know that I was going to need to be able to see the range hood duct work and the dryer duct. She said the dryer duct is already sheetrocked over and she used the flexable connector in the wall. I let her know that the flexable connector isn't allowed to be conceled with in the construction of the house and it would have to be changed.
