As a general rule, historically, tandem garages are generally expected to have at least twenty feet per space. Thirty or so feet just doesn't rise to the level of a two car, as a general rule. If THE MAJORITY of buyers and sellers in your market would consider the subject to have a two car garage, then you should consider it to be so. If not, then it is a one car plus. It's pretty cut-and-dried, conceptually. In my area, the number of parking spaces is secondary - garages and carports are valued by area, not parking space count.
