Powers Building is a historic office building located in Rochester in Monroe County, New York. It was built in 1869 and is a nine-story, 165-by-171-foot (50 by 52 m) building, laid out around a large open stairwell in the center. It features a triple mansard roof and observation tower which were added after initial construction, between 1873 and 1888, by Daniel Powers to maintain its standing as the tallest building in Rochester.[3] It was designed by noted Rochester architect Andrew Jackson Warner.[4]
It was listed on the National Register of Historic Places in 1973.[1] In 2019, the adjacent Powers Hotel was also added to the listing.[2]
