It also represents community planning and development as part of a carefully laid out group of buildings across a large planned area. Its siting shows Rice's treatment of buildings as sculptural volumes closely tied to the land.","narrative":"Set on a ridge in Rancho Santa Fe overlooking a valley to the north, this Spanish Colonial Revival house was designed by architect Lilian Rice in 1930. It began as a large single-story U-shaped building, with a second story added to the north wing in 1935. Walls are white-painted stucco over a wood frame, and the gabled roofs are covered in red clay tile. Overlapping rooflines in the rear patio resemble fans, and a chimney at the east end has a triangular spark arrester made of clay tile. A low wall and a tile-roofed entry gate enclose the patio. The original 1930 garage also survives, while a 1957 pool and a 1960s cottage came later. The house was listed for its architecture and its role in the planned development of Rancho Santa Fe. It shows Rice's placement of buildings as sculptural volumes spread informally across the site and attached to the land, among boulders and arroyos.","period_of_significance":"1930-1935","architect_builder":"Rice, Lilian Jenette; Carpenter, Armand","architectural_style":"Spanish Colonial Revival","criteria":["C"],"status_note":"Still used as a single dwelling; the form reports few alterations, including a 1987 balcony and some interior walls removed to enlarge the kitchen.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:28.098772-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/91000941.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/91000941/4a6764a5f4-800.webp","url_1600":"https://nationalhistoricalregister.com/media/91000941/4a6764a5f4-1600.webp","licence":"Public domain","author":"Jack Boucher","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Stoltzfus-Humphries_House_(Rancho_Santa_Fe,_CA).jpg\" rel=\"noopener\">Jack Boucher</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Stoltzfus-Humphries_House_(Rancho_Santa_Fe,_CA).jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123857760","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q5754453"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/san-diego-county/carmichael-norman-and-florence-b-house-91000941/"}
