As Gunner stated not required.
Could be written as Safety Concern (source of ignition of combustible vapor from the garage area.)
The only feasible source of combustion air would be through the vent chase up into the attic. This is a split foyer so the garage doesn't have an attic.
I bet the builder argued the closet was built as part of the conditioned space since it is closed off from the garage and it has fire rated doors with a self closer. That in itself is a little funny since the garage access door from the house, not too far from the closet area, doesn't have a closer.
So far, I have considered it a "what should be" safety issue.
