It is one of the largest early wooden apartment buildings in the Bay Area. Its clinker brick base, cast plaster ornament, mix of Colonial Revival and Craftsman styles, and rational courtyard plan are also cited. It serves as a neighborhood landmark.","narrative":"Madison Park Apartments is a five-story, 98-unit apartment building at 9th and Oak Streets in Oakland, completed in 1908. Charles MacGregor, a lumberman who later formed his own contracting company, designed and built it for about $125,000. The wood-frame structure sits on a base of clinker brick and is clad above in horizontal rustic siding, with three-sided projecting bays and a deep eave decorated with cast plaster modillions, egg-and-dart molding and dentils. Courtyards and lightwells give every room direct light. Inside, many apartments keep original fixtures, claw-footed bathtubs, Craftsman doors and Murphy beds with beveled mirrors. The building reflects the apartment construction boom around the East Bay after the 1906 San Francisco earthquake. Advertisements of the time called it the largest on the Pacific Coast, and it remains one of the largest early wooden apartment buildings in the Bay Area. Its size and corner site also make it a landmark among newer government and institutional buildings nearby.","period_of_significance":"1900-","architect_builder":"Charles MacGregor","architectural_style":"Colonial Revival and Craftsman","criteria":[],"status_note":"Marked occupied and used as apartments; the exterior appears unaltered, the interiors are largely intact, and corridor alterations date from 1929-1938.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:31.266029-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/82002164.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/82002164/5f6da042b7-800.webp","url_1600":"https://nationalhistoricalregister.com/media/82002164/5f6da042b7-1600.webp","licence":"CC BY-SA 3.0","author":"Almonroth","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Madison_Park_Apartments-2.jpg\" rel=\"noopener\">Almonroth</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:Madison_Park_Apartments-2.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123858268","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q133253406"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/alameda-county/madison-park-apartments-82002164/"}
