Public Service Building, High-rise building in Portland, Oregon.

The Public Service Building is a 15-story high-rise located in downtown Portland that showcases Italianate architectural details like decorative brackets and arched windows on its facade. These design elements extend across the entire structure, creating a cohesive visual presentation throughout.

The Public Service Building opened in 1928, built for the Portland Gas and Coke Company and the Pacific Power and Light Company, whose utility operations gave the building its name. Architect A. E. Doyle died in January 1928, three weeks after it opened. Charles K. Greene began the design but left Portland before completion, and Pietro Belluschi finished the project. The north and south wings were raised from two to twelve stories in 1957.

The name refers to the gas and electric companies housed here, which were considered "public services" in their day. Pietro Belluschi designed the lobby elevator doors to represent these utility tenants. The ground floor at Sixth and Salmon held the first Niketown store, opened in November 1990 and closed in October 2011.

The building is centrally located in downtown Portland and is easily accessible on foot from public transportation hubs. Daytime visits work best for viewing the architectural details clearly illuminated on the exterior.

The city's main power plant once occupied the basement; that space now holds Portland's main power feeds. On the roof, the utility tenants mounted neon signs reading "POWER", "HEAT", "GAS" and "LIGHT", each facing a cardinal direction, and at some point all four sides read "PACIFIC POWER". The signs and original red clay tile roof were removed in 1973.
