The original section was built in 1920 and a major hotel addition followed in 1926.","why_significant":"The nomination argues the hotel was the only noteworthy hotel in Hayward for about a quarter-century and served as a hub of the town's social and civic life. It also presents the building as the most distinguished surviving vintage commercial architecture in old downtown Hayward, designed by architect George L.F. O'Brien. The building retains a high degree of integrity after a certified rehabilitation.","narrative":"Standing at the corner of B and Main Streets in Hayward, this two-story building began in 1920 as a commercial block with shops below and offices above, built for the Eggert brothers, Herman and Henry Jr. In 1926 a large addition along Main Street turned it into a hotel, named for the green shutters beside its upper windows. Architect George L.F. O'Brien is documented as designer of the 1926 section. The street faces combine Colonial Revival detail with some Spanish Colonial Revival elements, and the ground floor keeps 1920s storefronts with bronze-framed windows, marble bulkheads and prism-glass transoms. The hotel mattered because Hayward had lost its earlier hotel in 1923. It hosted civic clubs, weddings and political events, and housed teachers, clerks and travelers. Its importance faded after 1945 as strip commercial development and motels drew business away. A recent seismic upgrade and rehabilitation restored missing elements, though the original cornice was not replaced.","period_of_significance":"1920 to 1945","architect_builder":"O'Brien, George L.F.","architectural_style":"Late 19th/early 20th century American movements (Colonial Revival with Spanish Colonial Revival elements)","criteria":["A","C"],"status_note":"Recently seismically upgraded and rehabilitated; ground-floor shops are in use and the building is described as structurally and commercially viable again.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:29.741933-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/04000594.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/04000594/e82733b4f7-800.webp","url_1600":"https://nationalhistoricalregister.com/media/04000594/e82733b4f7-1600.webp","licence":"CC BY-SA 3.0","author":"Sanfranman59","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Green_Shutter_Hotel_(Hayward,_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:Green_Shutter_Hotel_(Hayward,_CA).JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123858234","wikipedia":"https://en.wikipedia.org/wiki/Green_Shutter_Hotel","wikidata":"https://www.wikidata.org/wiki/Q5603202"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/alameda-county/green-shutter-hotel-04000594/"}
