Fullerton Post Office
Also known as: Commonwealth Post Office; Commonwealth Station

Why it's listed
Fullerton's post office, at the corner of Commonwealth and Pomona Avenues, opened in November 1939 as one of several Depression-era federal projects in the city. Designed by the Treasury Department's Office of the Supervising Architect, it is a symmetrical single-story reinforced concrete building with a full basement. Spanish Colonial Revival features include an arched entryway, a low-pitched clay tile roof, wrought iron details, flat stuccoed walls, and cast-iron lamps. It was placed beside the train station to speed mail handling. Inside, a long lobby with dark wood and terra-cotta finishes follows the standard 1930s post office plan. Above the postmaster's door hangs "Orange Pickers," a 1942 oil mural by Paul Julian, commissioned by the Treasury Department Section of Fine Arts. It shows citrus picking alongside oil and aviation, the town's other main industries. Alterations have been minor, and the building still serves as a post office. Its architecture, intact design and mural are the basis for its listing.
Significance in brief: The building is presented as a well-preserved example of Spanish Colonial Revival civic architecture from the Depression era, and as the only federal building in Fullerton. It also holds the 1942 "Orange Pickers" mural by Paul Julian, commissioned by the Treasury Department Section of Fine Arts, which has remained untouched and in excellent condition.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
