Lexington firefighters are trying to determine what caused a house fire early Wednesday morning on Addie Street.
Fire crews were called to the house, just off Fifth Street, about 5 a.m.
Several people apparently were living in the house, and all escaped safely, firefighters said.
There was relatively minor smoke and water damage, firefighters said.
Never miss a local story.
Initial indications are that the blaze started in a crawl space, but the cause remains unknown, firefighters said.
The Red Cross is arranging shelter for residents from the house.
