The original market was built in 1917 to designs by Oliver and Thomas, with matching additions through 1940.","why_significant":"The nomination argues it embodies the distinctive characteristics of an early 20th-century public market building under Criterion C. It is described as the only surviving local example of the type. Its steel-truss open hall, corner entries, glazing, clerestories and polychrome terra-cotta ornament reflect the era's emphasis on sanitary, bright food markets.","narrative":"Occupying an entire downtown Oakland block, this market complex began in 1917 as the Oakland Free Market, later called the Sanitary Free Market and then Swan's 10th Street Market. The original T-shaped hall was designed by Oliver and Thomas, with brick walls, steel trusses, clerestory windows and corner entries. White glazed brick and polychrome terra-cotta medallions of fruits and vegetables decorate the facade. Additions in 1918, 1925, 1926, 1927 and 1940, by architects including William Knowles and Edward Foulkes, matched the original design. The market reflected a push for hygienic, well-lit food retailing that welcomed women shoppers. It is described as the only surviving local example of its type. Alterations included a 1952 sign and a 1973 tile wall, and the 1989 Loma Prieta earthquake destroyed the Clay Street facade. A rehabilitation completed in 2000 restored much of the exterior and adapted the building for retail, housing and offices.","period_of_significance":"1917 - 1940","architect_builder":"Thomas, Leonard; Knowles, William; Foulkes, Edward","architectural_style":"Late 19th and Early 20th Century: Commercial Style","criteria":["C"],"status_note":"Rehabilitated in 2000 as a mixed-use complex with retail, restaurants, a market hall, offices and co-housing; the Loma Prieta earthquake damage and 1973 alterations were largely reversed.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:27.940945-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/01000826.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/01000826/1a38276e30-800.webp","url_1600":"https://nationalhistoricalregister.com/media/01000826/1a38276e30-1600.webp","licence":"CC BY-SA 3.0","author":"Sanfranman59","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:10th_St._Market_(Oakland,_CA).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:10th_St._Market_(Oakland,_CA).JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123858131","wikipedia":"https://en.wikipedia.org/wiki/10th_Street_Market","wikidata":"https://www.wikidata.org/wiki/Q4547162"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/alameda-county/10th-street-market-01000826/"}
