The Museum tells the stories of 97 Orchard Street. Built on Manhattan's Lower East Side in 1863, this tenement apartment building was home to nearly 7,000 working class immigrants. They faced challenges people understand today: making a new life, working for a better future, starting a family with limited means. In recognizing the importance of this seemingly ordinary building, the Tenement Museum has reimagined the role that museums can play in modern lives.

The museum offers exhibits, tours, educational programs, and educational and recreational events.

The Society operates a museum in the historic Paddock Mansion in downtown Watertown, New York. Listed on the National Register of Historic Places in 1979, the mansion was formerly the home of local banker Edwin L. Paddock and his wife, Olive. The home was designed in the Eastlake tradition by architect John Hose, and combined Tuscan Villa elements "for him" and Swiss Chalet "for her." It was built between 1876 and 1878 by John Griffin. Mrs. Olive Paddock bequeathed the home to the Society in 1922, and it was opened as a museum in 1924. The museum contains both Paddock family and local history exhibits, spread throughout three floors and within three outbuildings.

The museum offers exhibits, tours, lectures, research library access and educational and recreational programs.
