William Haas commissioned the house at 2007 Franklin Street in 1886 as a family home. Haas was a partner in a wholesale grocery business and among the successful German-Jewish merchant families who built substantial homes in the Western Addition and Pacific Heights neighborhoods in the late 19th century. The architect Samuel and Joseph Cather Newsom designed the structure in the Queen Anne style — steeply pitched rooflines, decorative shingles, a corner tower, and extensive millwork.
The house passed through the Haas family and then to the Lilienthal family, who were relatives by marriage, over the subsequent decades. The 1906 San Francisco earthquake and fire destroyed much of the city; the Franklin Street house survived with minimal damage, which was attributed to the quality of its construction and its location. The structure remained a private residence until 1973, when the Lilienthal family donated it to San Francisco Heritage, a preservation organization that operates it as the sole intact Victorian-era private house open to the public in San Francisco.
The house retains original furnishings and decorative elements across three primary floors plus the attic and basement. Regular guided tours have been offered since the 1970s. SF Heritage has expanded public programming to include the annual Halloween-season Mayhem Mansion events, which draw on the house's ghost reputation as well as its well-documented history.

Apparition of seated older womanApparition of man in chauffeur uniformMoving objectsWindows opening without cause
The reported activity at the Haas-Lilienthal House comes, in part, from people who have spent substantial time inside it — docents and staff who work the building regularly. The accounts in available sources describe two recurring visual apparitions: an older woman seated in one of the upstairs rooms, observed by multiple people in the same location across different visits, and a man in a chauffeur's or service uniform seen near the back staircase.
The chauffeur figure is notable because it is a specific detail — the description implies staff rather than family, which in a house of this era and scale would correspond to domestic employees whose historical record is far less complete than the owners'. Whether the figure represents an actual individual associated with the house is unknown.
Additionally, staff and visitors have described objects moving of their own accord and windows opening without anyone approaching them. The Haunt Ghost Tours, a San Francisco ghost tour operator, has documented employee sightings at the house as part of its research into the city's paranormal sites.
SF Heritage, the nonprofit that operates the house, leans into the ghost reputation through its Mayhem Mansion annual event, suggesting a degree of institutional acknowledgment even if the organization does not make paranormal claims officially.
