They differ from it in use, because they were built as small residential flats for working-class people rather than as stores with lodgings. They add a residential and social dimension to the district.","narrative":"Three brick buildings on Osgood Place, a very narrow one-block street between Broadway and Pacific Avenue in San Francisco, form a small residential group beside the Jackson Square Historic District. Dating from about 1906-1907, they replaced earlier buildings lost or damaged in the Earthquake and Fire. The building at 25-47 has a symmetrical three-bay brick facade with diamond ornaments, corbels, keystones and bracketed cornices, and once held a stable for four horses and a cow. The building at 55 was designed by architects Perseo Righetti and Henry Kuhl. Behind the street fronts, rear frame structures and a brick-paved court with porches, bridges and gardens connect the units. The flats were small, housing working-class residents in an area once part of the Barbary Coast. Later occupants included artists, writers and musicians. The group was nominated as an addition to the neighboring district because its age and appearance match, while its residential use adds to the district's social history.","period_of_significance":null,"architect_builder":"Architects Perseo Righetti and Henry Kuhl (55 Osgood Place)","architectural_style":null,"criteria":[],"status_note":"Listed as in fair condition and occupied, in private residential use.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:32.174843-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/79000535.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79000535/f0897b707f-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79000535/f0897b707f-1600.webp","licence":"CC BY-SA 4.0","author":"Sanfranman59","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Old_Ohio_Street_Houses_(San_Francisco).JPG\" rel=\"noopener\">Sanfranman59</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Old_Ohio_Street_Houses_(San_Francisco).JPG"},"district":{"nrhp_refnum":"71000186","name":"Jackson Square Historic District","url":"https://nationalhistoricalregister.com/districts/california/jackson-square-historic-district-71000186/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123861228","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q133484698"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/san-francisco/old-ohio-street-houses-79000535/"}
