It holds 297 contributing and 35 noncontributing buildings, mostly 3- to 7-story apartment hotels built 1906-1925.","why_significant":"The district is a close-packed group of masonry apartment buildings that share a single Sullivanesque facade composition, with varied historicist ornament. Most were built 1906-1925 and remain largely intact, giving the area unusual stylistic consistency. It has always been residential, and the form contrasts it with the neighboring Tenderloin apartment hotel district.","narrative":"Covering about five blocks of three parallel east-west streets on the south slope of Nob Hill, this San Francisco district is made up almost entirely of 3- to 7-story apartment buildings and residential hotels that fill their front lot lines. Most went up between 1906 and 1925, and their facades follow a common Sullivanesque pattern of flat roofs, boldly projecting galvanized iron cornices and a column-like arrangement of wall and windows. Ornament varies from building to building, drawing on Classical, Renaissance, Mission/Spanish Revival and Art Nouveau motifs, with a few Art Deco buildings from the 1930s. About 46 percent of buildings are stucco and 42 percent brick. Roughly half have shops at street level, mostly serving residents. The district is listed because it preserves a cohesive, largely intact neighborhood of walk-to-work apartment housing from the early twentieth century, with 297 contributing buildings, distinct from the larger, more commercial Tenderloin to the south.","period_of_significance":null,"architect_builder":"Many architects and builders, including O'Brien Brothers, Rousseau & Rousseau, Bugbee & Bugbee and John Reid Jr.","architectural_style":"Late 19th and Early 20th Century American Movements; Late 19th and 20th Century Revivals; Renaissance (Sullivanesque composition)","criteria":[],"status_note":"Historic and current use is residential (multiple dwellings and hotels) with ground-floor commerce; most buildings are nearly intact, and condition ranges from barely habitable to newly renovated.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:27.689884-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/91000957.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/91000957/ae77984253-800.webp","url_1600":"https://nationalhistoricalregister.com/media/91000957/ae77984253-1600.webp","licence":"CC BY-SA 3.0","author":"Sanfranman59","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:740,_736,_730_%26_724_Leavenworth_St.,_Lower_Nob_Hill_Apartment_Hotel_District,_San_Francisco,_CA_9-3-2012_4-03-29_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:740,_736,_730_%26_724_Leavenworth_St.,_Lower_Nob_Hill_Apartment_Hotel_District,_San_Francisco,_CA_9-3-2012_4-03-29_PM.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123861199","wikipedia":"https://en.wikipedia.org/wiki/Lower_Nob_Hill_Apartment_Hotel_District","wikidata":"https://www.wikidata.org/wiki/Q7699632"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/san-francisco/lower-nob-hill-apartment-hotel-district-91000957/"}
