Several fire trucks responded to the Governor's Mansion Friday morning to investigate the source of smoke in the building.
A Bureau of Protective Services officer noticed smoke coming from a basement window around 7:45 a.m. during a routine patrol.
The smoke originated from a small fire in the basement laundry area, according to Haley's spokesman.
"The First Family was safely and quickly evacuated and are grateful for the work of first responders," said Godfrey.
Several of the firefighters who responded have cleared the scene. Some remain to help with ventilation.
The grounds of the Mansion, located at 800 Richland Street, include nine acres of land in the heart of the historic district of Columbia. It was built in 1855 and was spared during the burning of Columbia in the Civil War.
Two other houses, The Lace House and The Caldwell-Boylston House, are located on the grounds.
The cause of the fire is under investigation.
