Whole-house fan in garage?

Please see the photos. I would think a whole-house fan (non-temperature controlled; manual on/off switch, no timer) in the garage would be a no-no for fire stop reasons…

You got that right.

If the living space shares the same attic space as the garage I would say it is a no-no.let’s see what the others say.

It does. Please see the photo. Attic access in garage. This was taken from attic access hatch…no separation.

Then you should write it up as a safety defect.

Yes siree, Bob!
