The townhouse near S. Buchanan Street and 29th Street was vacant and undergoing renovations.
Arlington County Fire Department spokesman Capt. Gregg Karl says the fire started in the basement where construction work was taking place, and spread to the first level. The first and second levels sustained heat and smoke damage.
The fire is currently out and crews are beginning to be released from the scene. The Arlington County Fire Marshal’s office has a representative at the townhouse to begin the investigation.
No construction workers or fire fighters were injured.
