Residential Units - Pressure Testing

We have a residential (apartment) building that is allowing smoking on one of the floors. After blower door testing and reparations, we have met the requirement for unit sealing. The rooms are served ventilation via a central system with under-door cuts into each unit, and we intend to show compliance via design for proper positive pressure differential from the hallways to the space (in lieu of weatherstripping). Will we also need to complete pressure testing for these units, per the non-residential requirement? Or will the mechanical design documentation suffice? Thanks!
