Firefighters were called around 9:00 Friday morning to a fire at the Cambridge Apartment Complex.
Good Samaritans jumped into action to make sure everyone got out safely.
They went door to door, warning residents about what was happening and even kicked in doors when no one answered.
Firefighters say it took them about fifteen minutes to put out the fire.
One person was sent to u-k hospital to be treated for smoke inhalation.
Firefighters say six apartments were unlivable after the fire.
