Ryan House, Heritage building in Sumner, United States.

Ryan House is a single-family residence in Pierce County featuring pioneer-era construction with additions built during the 1800s. The structure combines an original log cabin core with later expansions that reflect the family's growing needs.

Fred Seaman built the house as a one-room cabin. George Ryan bought the property in 1872 and added onto the house in 1875 and 1885. In 1926, Ryan's family donated it to the town of Sumner for use as the Sumner Public Library, which operated there until 1979. The Sumner Historical Society then ran it as the Ryan House Museum until its demolition on 25 July 2025.

The Ryan family donated the house to the town of Sumner in 1926 for use as the Sumner Public Library, which operated there until 1979. The Sumner Historical Society then took over the building and runs it as the Ryan House Museum, displaying local history.

The property is listed on the National Register of Historic Places, ensuring legal protection and specific maintenance standards for the structure. Visitors should expect limited hours and occasional closures, as access to historic homes can vary seasonally or for restoration work.

The house was demolished on 25 July 2025, after the Sumner City Council voted on 18 September 2023 to raze it for a park. A citizens' group, Save the Ryan House, had won a March 2024 Pierce County Superior Court ruling that the city had not given the public sufficient notice, but the demolition went ahead anyway.
