Industrial buildings are very rare in Curlett's known work, and this is the best surviving San Francisco example of that type by him. It also represents immediate post-1906-fire construction of a factory making candy of all types for the George Haas & Sons chain.","narrative":"Rising five stories at the corner of Mint and Jessie Streets in San Francisco, this reinforced concrete building clad in brick was completed in 1907 as a candy factory for George Haas & Sons. The firm, wiped out in the 1906 earthquake and fire, rebuilt quickly and used the factory for 21 years to supply its chain of retail stores, which grew to eight branches. The building was designed by William Curlett, a respected San Francisco architect known for bank, office and residential work. Industrial buildings by him are very rare; most have been demolished, and another attributed example was heavily altered. Details include corbelled cornices, string courses, segmental relieving arches and round-headed windows on the top floor. Later changes include painted brick, a rebuilt rear section after the 1989 Loma Prieta earthquake, and conversion to a restaurant and offices. It is valued locally as Curlett's best surviving industrial work.","period_of_significance":"1906","architect_builder":"Curlett, William FAIA","architectural_style":"Late 19th/Early 20th Century Commercial Style","criteria":["C"],"status_note":"Now holds a restaurant on the ground floor and offices above; the brick exterior has been painted and the rear elevation altered after earthquake damage in 1989.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:27.003791-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/00001622.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/00001622/6bdf63ae48-800.webp","url_1600":"https://nationalhistoricalregister.com/media/00001622/6bdf63ae48-1600.webp","licence":"CC BY-SA 3.0","author":"Sanfranman59","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Haas_Candy_Factory_(San_Francisco)_2.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:Haas_Candy_Factory_(San_Francisco)_2.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123861141","wikipedia":"https://en.wikipedia.org/wiki/Haas_Candy_Factory","wikidata":"https://www.wikidata.org/wiki/Q133458411"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/san-francisco/haas-candy-factory-00001622/"}
