Class 9a health-care buildings, class 9b early-childhood centres, Class 2 and 9c buildings and Class 4 parts of a building must be provided with laundry facilities. Under the F4F2 Application provision, F4F2 does not apply to any other classification of buildings. Class 2 and 9c buildings and Class 4 parts of a building are required to have laundry facilities and means to dispose of waste water because occupation is generally of a permanent nature. This is not the case in other buildings. For example, a hotel, motel or boarding school may have its own laundry facilities, or have arrangement with a commercial laundry. Sole-occupancy units in Class 3 buildings are not occupied by the same people for extended periods of time, so they are not required to be provided with laundry facilities or means to dispose of waste water.
