One person who complained of breathing in too much smoke was taken to a hospital from a fire at the Lofts at Willow Creek in Beavercreek late Wednesday night.
Cooking left on the stove is being blamed for the fire, which left a third-floor apartment and one below it uninhabitable, Beavercreek Twp. Fire Lt. Matt Clark said.
The sprinkler system kept the fire in check and extinguished it quickly.
Lt. Clark estimated the damage to the apartments and their contents at $20,000.
The person taken to a hospital suffered from smoke inhalation, he said.
