Figure this one out. You are on the garage side. Pass or fail?

The Vapor Barrier Faces The

Well... I would fail it because they did a terrible job installing the insulation.
Vapour barrier needs to go on the side of the assembly with high moisture drive. In our climate (cold/dry) the vapour barrier goes on the other side (inside) of that wall. In Florida (warm/wet) vapour barrier would need to go on the outside of the wall assembly.

Is the garage conditioned? If not, then what is the purpose of the insulation, is it now just sound insulation?

garages are considered non conditioned spaces and are often non insulated. Workmanship aside, I wouldn't look closely.

Yes, and the other side of that wall is the interior of the house.

BUILDING THERMAL ENVELOPE. The basement walls, exterior walls, floors, ceiling, roofs and any other building element assemblies that enclose conditioned space or provide a boundary between conditioned space and exempt or unconditioned space.

darn, I assumed it was exterior wall. My bad.
In this case, the insulator has to provide a bit more effort in the placement of bats. VB on the warm side.

A vapor barrier is not required only an air barrier between the house and the garage.
AIR BARRIER. One or more materials joined together in a continuous manner to restrict or prevent the passage of air through the building thermal envelope and its assemblies.
The IRC requires R-13 not R-11 so it is a fail.

Oh Well
Is that a 4' segment of shear wall between the HDs? Or does the braced wall extend to the left and right of the HDS?
Some jurisdictions require the insulation to be cut out around the outlet boxes.
