Firefighters responded to the condos on the 14800 block of Endicott Way, just northeast of the Pilot Knob Road-County Road 42 intersection, at about 8 a.m.
The four-alarm fire saw Apple Valley firefighters and fire crews from neighboring communities battling a fire that had spread to all three floors of the 16-unit complex.
An adult male resident of the condos was taken to the hospital to be treated for burns and smoke inhalation, officials said. A firefighter also was transported to the hospital after getting caught under a ceiling that caved in inside the complex; the firefighter’s injuries were reportedly non-life threatening.
The cause of the fire had not been determined as of noon Friday.
