Millbrae Avenue, corner of California Drive, in Millbrae, San Mateo County, California. The present building was completed in 1907 on the site of earlier depots.","why_significant":"The depot is argued to be important to the growth and prosperity of Millbrae, which was a large rancho with few inhabitants before the railroad arrived. It is a typical early-1900s depot with a Colonial Revival look. The site has housed depots since 1864, and the first post office was located in the depot in 1866.","narrative":"A two-story wood-frame railroad depot stands at the corner of Millbrae Avenue and California Drive in Millbrae, California. Completed in 1907, it has a hipped wood-shingle roof, a covered portico on the track side, and living quarters on the upper floor. The ground floor holds a waiting room, an office with a ticket window, and a baggage room. It was built on the site of Millbrae's first depot, completed in 1864 by the San Francisco & San Jose Railroad on land deeded by Darius Ogden Mills. Earlier depots burned in 1890 and 1906. The town's first post office operated from the depot starting in 1866. The nomination argues that the railroad stop was central to the growth of a community that had been a large rancho with few residents. At the time of listing the building was still serving passengers, needed repainting and roof work, and was planned to be moved 200 feet south for road widening.","period_of_significance":null,"architect_builder":null,"architectural_style":"Colonial Revival","criteria":[],"status_note":"Still in use as a depot and ticket facility at the time of nomination; in need of repainting and roof repair, and slated to be moved 200 feet south to allow widening of Millbrae Avenue.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:32.009243-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/78000770.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/78000770/4d0a3cc429-800.webp","url_1600":"https://nationalhistoricalregister.com/media/78000770/4d0a3cc429-1600.webp","licence":"CC BY-SA 3.0","author":"Sanfranman59","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Southern_Pacific_Depot,_21_E._Millbrae_Ave.,_Millbrae,_CA_7-31-2011_6-25-16_PM.JPG\" rel=\"noopener\">Sanfranman59</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Southern_Pacific_Depot,_21_E._Millbrae_Ave.,_Millbrae,_CA_7-31-2011_6-25-16_PM.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123861568","wikipedia":"https://en.wikipedia.org/wiki/Southern_Pacific_Depot_(Millbrae,_California)","wikidata":"https://www.wikidata.org/wiki/Q133522110"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/san-mateo-county/southern-pacific-depot-78000770/"}
