Hi Guys,
Hope everyone is enjoying their Sunday.

Im proposing new ductwork on the non habitable cellar of a 1 family dwelling. The ceiling height is 6'-10" the proposed duct is going to be 8"x18" high which is going to bring the headroom directly under it to 6'-2" - as per 2020 RC of NYS R305.1 exception 3 "Beams, girders, ducts or other obstructions in basements containing habitable space shall be permitted to project to within 6 feet 4 inches (1931 mm) of the finished floor."

im not habitable so this is not applicable to my condition but, is there anyway else i should look at for a minimum headroom since you need to traverse under it from one storage area to another?

Thank you in advance.

sorry, forgot to mention that there is already a timber jost spaning between the 2 storage rooms bringing the headheight between the storage spaces to 6'-2" thats why i kept the height of the duct at 8" instad of 6" (to give you the 6'-4")
