The Cal Shaw Adobe Duplex is an adobe house located at 129 Central Street in Tonopah, Nevada. The house, which was built in 1905, is typical of the adobe homes commonly built in Tonopah in the early 1900s. The building's exterior is scored to resemble stone; the home's design also features a decorative frieze and a porch supported by turned columns. The home has changed little since its construction and has been called "the best preserved adobe residence in Tonopah" by a local historic survey. The house was added to the National Register of Historic Places on May 20, 1982.
