Fire crews responded to a report of a fire at a three-story apartment complex at 280 East O'Keefe St. at 12:03 a.m., Menlo Park Fire Protection District Chief Harold Schapelhouman said.
The fire originated on the second floor, in the back of the building, and was caused by an unattended pot on the stove, Schapelhouman said.
A female was trapped inside on the second floor, but firefighters were able to rescue her and transport her to a hospital for treatment, the chief said.
Schapelhouman said that two other women were in the apartment at the time of the fire, but self-evacuated and were transported to a hospital.
One firefighter from the first responding crew suffered from smoke inhalation, but remained at the scene, he said.
None of the injuries are considered life-threatening, Schapelhouman said.
The fire was out at about 12:45 a.m., Schapelhouman said.
Schapelhouman said the majority of the damage was done in the second floor, but the third floor sustained some smoke damage.
Six people, three women from the unit on fire and three others from a separate unit, were displaced, Schapelhouman said.
The unit sustained about $100,000 to $150,000 in damage, and another $20,000 to $25,000 in contents were lost.
