Fire crews responded quickly to a call at Westmont College in Montecito yesterday, where they extinguished flames in a closet at the Page residence hall.
The fire took place around 6 pm, and forced 200 students from their rooms for the night.
Power was also cut from the building as a precaution.
Investigators believe a camping stove was in use in the closet where the fire broke out.
One student was transferred to cottage hospital for the night with burn injuries.
