Tharp.","why_significant":"It is argued to be architecturally significant as a nearly intact Craftsman/Tudor Revival facade, the only firehouse known in that style in San Francisco. It is one of the few surviving firehouses built after the 1906 earthquake and fire, and it reflects the work of City Architect Newton J. Tharp. It is cited in a national study as an example of residential-influenced Tudor Revival firehouse design.","narrative":"Engine House No. 31, also called the Russian Hill Firehouse, is a frame firehouse at 1088 Green Street in San Francisco. Built in 1908 to a design by City Architect Newton J. Tharp, it replaced firehouse capacity lost in the 1906 earthquake and fire. Its symmetrical facade mixes Craftsman and Tudor Revival elements, including false half-timbering, a flared dormer and a wide center bay. Tharp reportedly designed it to fit the private residences of the neighborhood. Of about 24 firehouses the city built between 1906 and 1912, only seven survive, and this is the only one known in this style. The fire company left in 1952, and a private owner bought the building in 1958, restoring it as a residence above with a small fire memorabilia museum and meeting space below. Much of the original tongue-and-groove interior, a cast-iron spiral staircase and the facade survive, making it a well-preserved example of post-fire municipal architecture.","period_of_significance":"1908","architect_builder":"Tharp, Newton J., City Architect; contractor John Dahlin","architectural_style":"Tudor Revival; Bungalow/Craftsman","criteria":["C"],"status_note":"Used as a private residence upstairs, with meeting and museum rooms downstairs for community groups; most original interior and facade remain.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:27.882681-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/87002290.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/87002290/4ea77a73fd-800.webp","url_1600":"https://nationalhistoricalregister.com/media/87002290/4ea77a73fd-1600.webp","licence":"CC BY-SA 4.0","author":"Sanfranman59","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Engine_House_No._31_(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:Engine_House_No._31_(San_Francisco).JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123861093","wikipedia":"https://en.wikipedia.org/wiki/Engine_House_No._31_(San_Francisco,_California)","wikidata":"https://www.wikidata.org/wiki/Q60521329"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/san-francisco/engine-house-no-31-87002290/"}
