The Orange County Communications Center dispatched fire engines to a structure fire call on Ashley Forest Road at about 10:37 p.m. Monday.
When the first engine company arrived about two minutes later, the apartment and those adjacent to it had been evacuated.
Firefighters extinguished the fire quickly and confined it to a bedroom.
Orange County EMS transported the apartment’s occupant to the hospital to receive treatment for smoke inhalation.
The investigation following the fire found that neighbors woke the occupant after hearing a smoke alarm and attempted to put out the fire with a fire extinguisher.
Investigators determined improperly extinguished smoking materials caused the fire and estimated structure damage to be about $2,000.
