The Mississippi Governor's Mansion is undergoing $425,000 in maintenance before the new occupants can move in.
Work started Jan. 16 and should be finished by mid-April.
Until then, Gov. Phil Bryant and his wife, Deborah, continue living in their own home in Rankin County, outside Jackson.
The state Department of Finance and Administration says work includes mechanical modifications to the heating and air conditioning system and cleaning and re-coating of duct work.
The outside of the mansion is being repainted, as is the metal fence surrounding it. Gazebos outside are getting new roofs.
The oldest part of the mansion dates to 1842. The state Department of Archives and History says it's the second-oldest continuously occupied governor's residence in the nation.
It was designated a National Historic Landmark in 1975.
