Cool.
Which inspector, your friend or the one I mentioned?
What's no problem? No fireblocking?

Cause what you described below implies you have NO fireblocking, but without seeing a section, I don't know for sure. But I can guess, see below.
Excuse me? Without seeing a section at each of the double walls I wouldn't know what you are talking about. If the airgap is enclosed by drywall on the studio leaf, and the garage exterior shiething , that implies two things. I understand your "inside out" studio wall construction. And you say this is in a garage..which implys an unshiethed interior framing, which is probably fireblocked but useless unless drywalled. You have an airgap between the exterior shiething and the drywall on your studio wall, and this airgap is open to the space above your studio, no? This means, there is nothing in the airgap to keep fire from spreading to an attic space, unseen, should a fire start within. However, if your garage was drywalled in the first place, then you must have a three leaf system

, which for all intents an purposes creates a drywalled plenum..with no firestop.
And actually, thanks for the description. You have now become one of the people here that you just called full of shit.
But thanks for the final vote of confidence. I appreciate it. Good luck getting a pool table.
