The 1912 Mahoney Administration Building is one of the few remaining government buildings in the Valley that dates to the year of Arizona’s statehood. Identified by Phoenix Magazine as one of the city’s “hidden gems;” the building represents the first institutional commission for the architectural engineering firm of Lescher & Kibbery (later Lescher & Mahoney).
The building housed executive office and living quarters for the hospital superintendent’s family. It is the oldest remaining structure on the Arizona State Hospital campus and one of the earliest remaining examples of Mission Revival-style architecture in Phoenix.
Today, the Mahoney Building stands vacant and in a state of disrepair. The building’s exterior retains much of its historic character, despite some weather deterioration. Although nearly 100 years old, the building is structurally sound because it was constructed with the most advanced technology of the period. The Arizona Historical Advisory Commission (AHAC) has recognized the Mahoney Building’s historical significance by designating it as one of the Arizona Centennial’s state Legacy Projects.
A dedicated group of volunteers led by Susan Gerard, a former state health director and health leader at the Legislature, is working hard to restore this historical treasure. With Arizona’s Centennial fast approaching, plans to restore the building hinge on finding funds and community support.
