It is also said to be the only unaltered surviving Victorian block in Oakland, with a near-original interior and a surviving out-building tower. It also reflects the commercial growth of downtown Oakland after the transcontinental railroad arrived in 1869.","narrative":"Dunns Block is a three-story brick hotel with a full basement at 725 Washington Street in Oakland, built in 1876 by John Dunn. Its upper floors have four bay windows, and its ornate facade, carved details and splendid cornices rest on cast iron pillars made in San Francisco in the 1870s. Inside, the original floor layouts, graining, plaster ornament and 14-foot ceilings survive largely undisturbed, and a three-story toilet tower connected by ramps still stands behind it. The nomination describes it as the only unaltered Victorian block left in Oakland. The hotel was located near the main 7th Street railroad station and belonged to the downtown that grew after the transcontinental railroad arrived in 1869. As commerce moved uptown, the building declined, later serving as a transient hotel and a used-goods shop. At nomination it was condemned but structurally sound, and it sat within an area slated for preservation and rehabilitation as Old Oakland.","period_of_significance":"1800-1899 (specific date 1876)","architect_builder":"John Dunn","architectural_style":"Italianate Victorian","criteria":[],"status_note":"Condemned and unoccupied at the time of nomination; deteriorated but structurally sound, with the interior little altered from 1876.","vacant_flag":true,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:31.766043-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/78000652.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/78000652/5b7797560f-800.webp","url_1600":"https://nationalhistoricalregister.com/media/78000652/5b7797560f-1600.webp","licence":"CC BY-SA 3.0","author":"Sanfranman59","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Dunns_Block_(Oakland,_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:Dunns_Block_(Oakland,_CA).JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123858204","wikipedia":"https://en.wikipedia.org/wiki/Dunns_Block","wikidata":"https://www.wikidata.org/wiki/Q123232179"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/alameda-county/dunns-block-78000652/"}
