Does this duct have dampers on both sides of the wall in question?

This is a bit of a tricky question as the answer is to be found under IRC Section R309.1.1, Garage Seperation.
It may seem that you would find it under Dwelling Unit Seperation Section R316. Reading further you will find in section R317 that the Townhomes and other such dwellings are to be considered seperate buildings and they are to contain no plumbing or mechanical ducts or vents. This would preclude a duct passing through such wall.

Agreed - fire/smoke dampers needed.

Sort of a code question indeed Claude as most of what we inspect has some basis in a code somewhere.
26 gauge steel is the answer I was looking for.
As for smoke dampers David please enlighten me.
