It is owned by the City of Concord and used as a meeting house.","why_significant":"The nomination argues the adobe is significant for its adobe construction and its role in the exploration and settlement of California. It is described as either the first or second permanent structure built in what is now Concord and as an excellent example of Mexican California architecture. It retains more than 80 percent of its original material and much of its rural setting.","narrative":"This one-story adobe on Grant Street in Concord was built in the 1840s for Don Fernando Pacheco on Rancho Monte del Diablo, a land grant given to his father, Salvio Pacheco, in 1834. The walls are about two feet thick and made of adobe blocks, with a gabled roof, an attic, and a brick-paved front veranda. A wood-frame lean-to was added at the rear. The house was lived in by Pacheco and later his daughter Bersabe until 1918, then stood empty for about twenty years. A county sheriff and the Contra Costa County Horsemen's Association restored it in 1940-1941, and it has since served as a meeting place and museum. It is considered significant for its adobe construction, its link to early settlement of the area, and its Mexican-period architecture. More than 80 percent of the original material remains, though the south wall is failing and the building needs conservation work. It is also a State Registered Landmark and a Concord city landmark.","period_of_significance":"1845 - 1855","architect_builder":"Don Fernando Pacheco","architectural_style":"Mexican California architecture","criteria":[],"status_note":"Occupied and used as a meeting house; described as deteriorated, with a failing south-end wall and a need for immediate conservation work.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:31.816838-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/80000798.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/80000798/9655cd17b1-800.webp","url_1600":"https://nationalhistoricalregister.com/media/80000798/9655cd17b1-1600.webp","licence":"CC BY-SA 3.0","author":"Sanfranman59","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Don_Fernando_Pacheco_Adobe_(Concord,_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:Don_Fernando_Pacheco_Adobe_(Concord,_CA).JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123858555","wikipedia":"https://en.wikipedia.org/wiki/Fernando_Pacheco_Adobe","wikidata":"https://www.wikidata.org/wiki/Q5292603"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/contra-costa-county/pacheco-don-fernando-adobe-80000798/"}
