Although official historic sources focus on the architectural significance of the Jacques Guibourd Historic House, paranormal investigators and others have documented accounts of hauntings and spiritual energy. The house is often included in the ghost tours of Ste. Genevieve, a town with a deep and occasionally turbulent history. Some visitors report a feeling of significant spiritual energy within the home, with one visitor on Wanderlog noting, "Lots of spiritual energy in the space". Local lore suggests the house is haunted by a "lady in black," whose presence has been reported by various witnesses. A paranormal investigation in 2021 was prompted by reports of a ghostly figure appearing at the house.
