An overnight fire destroyed a unit at the Vacaville Gables Apartment complex Monday morning.
The blaze began outside of the apartment as a grass fire before spreading to the building, according to the Vacaville Fire Department.
The complex's laundry room and rental offices were also damaged.
A security guard who patrols the complex was on a scene and said that that unit belongs to the manager.
Investigators are still trying to determine the cause of the fire.
