Narrative:

Aircraft X was an arrival aircraft with a gate wait and for as long as possible without disrupting traffic I let the aircraft remain short of its taxiway entrance until it began to inhibit my operation. At which time I instructed aircraft X to continue taxiing via alpha and to hold short of taxiway quebec. The pilot read back the instructions. Then aircraft Y; a departure called for taxi at which time I advised the pilot runway 31L; taxi via left bravo and to hold short of foxtrot. Additionally aircraft Z; a disabled aircraft on the movement area of taxiway bravo between victor and whiskey advised they needed assistance. An emergency vehicle said they were on their way to the aircraft which required a runway crossing. Aircraft X advised they were at quebec. I acknowledged with a 'roger'. But at that specific moment the vehicle also called clear of runway 31R and several other aircraft called for initial taxi instructions. Aircraft X then advised that aircraft Y's wing went over their aircraft. I responded that they were instructed to hold short of taxiway quebec. The pilot informed me they tried letting me know they were on quebec. Aircraft X had no damage to their plane and were instructed to taxi back to the ramp via bravo when their gate became available. To avoid the re-occurrence of this event I would recommend that if a pilot is instructed to hold short of a specific point and they make a mistake to advise the controller sooner than in this instance. I also believe that in the event ground control is as busy as it was maybe it would be beneficial to have the disabled aircraft and emergency vehicles talking to a ground control 2 if it could be open staffing permitted.
