With the smoke alarm blaring, one fire crew tackled a small blaze in the downstairs business, while two others entered the smoke-filled home upstairs.
Wearing breathing apparatus and using torches to find their way, the firefighters went from room to room, looking for occupants.
When Firefighter Cem Dincer found a locked bedroom, he forced the door and found the two teenage girls and a boy, huddled by a bed.
Firefighter Dincer alerted other firefighters, as he guided the residents to a rescue ladder placed against an open window.
The teens, who had followed fire safety advice they received from a FRNSW visit to their school, were not seriously hurt.
Fire crews cleared the building, extracted the smoke and identified an e-bike, charging in a downstairs kitchen, as the source of the fire.
