Fire crews reponded to the home, in the 1400 block of Maple Lane, just after 2 a.m. after receiving 911 calls about the blaze, said Ryan Montero of the Kent Fire Department.
The house was supposedly abandoned, but firefighters searched it anyway as a precaution - and found a man inside. They pulled him to safety as flames crackled around them and smoke permeated the home.
The man suffered some smoke inhalation and was taken to a hospital.
Firefighters extinguished the blaze within about 40 minutes, Montero said.
The cause of the fire is under investigation.
