I recently ran into some trouble with a tricky Town here.

Has anyone ever been required to install air tight recessed cans by a town or AHJ? Today the inspector failed my 6" IC rated cans and stated they need to be air tight. I have 15 years in the trade and work all over this county and have never heard anything like this before. As far as I know there is no energy code in force here like CA or WA.
