If you are addressing a dwelling unit condo with its own garage, the IBC would apply.
Yes, and that's a problem that should be fixed in the IRC immediately. Last week here in New Port Richey (FL) two teenagers died in their beds when a running vehicle in the garage poisoned them with carbon monoxide fumes. If anything needs to be a hard requirement this is it. I will write up this discrepancy as a serious safety hazard from now on.
