Inscription. The Oakland Plumbing Supply Company warehouse and showroom was one of the few buildings constructed in the District during the 1920s that did not serve a wholesale grocery purpose. The company was nevertheless a significant Port of Oakland customer and at its height was one of the largest distributors of plumbing, heating, and engineering supplies on the Pacific Coast. The building was used continuously as a plumbing supply warehouse and showroom first by Oakland Plumbing Supply Company and then by P. E. O'Hair & Company from its construction in 1929 until 1998 when it was converted into live-work lofts.
