Devereaux House, Victorian mansion in Salt Lake City, United States

Devereaux House, also called the Staines-Jennings Mansion, is a Victorian brick house in Salt Lake City with French-influenced detailing and a cement plaster overlay. A mansard roof forms the third floor, and a wide porch wraps around the south and east sides. Inside, a large stair hall opens to a drawing room on the left and a library on the right, with a banquet room behind the parlor and a dining room behind the library. The attic holds servants' quarters and a billiard room.

William Staines built this house in 1857, and William Jennings acquired it in 1867, naming it after his family estate in England. The house was home to the Jennings family for decades, reflecting changes in how it was used and maintained over time.

The house served as a social hub for Salt Lake City's elite, drawing prominent visitors and political leaders to its rooms. It reflects how wealthy families lived and entertained during the 19th century.

The house stands at 334 West South Temple, next to the Delta Center and the Triad Center, with the Salt Lake City Union Pacific Depot and The Gateway a short walk away. The yard has no perimeter fence and reads as a public park, so the exterior and grounds can be seen from the street. The Church of Jesus Christ of Latter-day Saints keeps it as a historic site and opens it only for occasional receptions and events, so check event access before planning a visit.

The house was the first building in the Salt Lake Valley on a scale that could be called a mansion. It was also the scene of a meeting between Brigham Young and Governor Alfred Cumming that helped resolve the Utah War. Brigham Young's eldest son, Joseph Angell Young, owned it briefly, buying it for $20,000 in 1865 and selling it for $30,000 in 1867.
