is this do-able?

Yes.

if so, is there generally a requirement for gypsum board or some other
fire
rated materials between the apartment floor and the parked cars beneath
it?

There is here, and likely is where you are.

Yes; like many of us the garage is 'storage'!
Best to comply with required local building and insurance codes.
But conditions of use might change?
For example ten-fifteen years from now, with perhaps a new owner etc, a
young man working on his own car late at night leaves it running while he
runs out with friend to get something at a food take-out.
A fire or a leakage of carbon monoxide occurs and someone in an apartment
above or the attached house is injured or killed!
Legal liability could be incurred and the home owner then may find that
their insurance is in invalid for renting an apartment in a building that
does not meet code?
Two cents.
