It is also significant in community planning as part of a carefully laid out group of buildings, and it likely set the tone for later design in the Civic Center area.","narrative":"Built in 1924 at 16915 Avenida de Acacias, this small office building was the first commercial structure in the planned community of Rancho Santa Fe. Lilian Jenette Rice designed it in the Spanish Colonial Revival style, using thick adobe walls finished in white stucco with green trim. Rounded corners, corner pilasters capped with flattened domes, recessed windows with molded arched surrounds and keystones, and a band of red clay tile below the eaves give it a distinctive character. Alterations have been modest: iron grillwork and the original heavy windows were removed, and the interior was reworked in 1935 to suit successive businesses. It continues to serve as business space. The building was recognized for its architecture as an early, well-preserved example of Rice's commercial work, and for its role in community planning as part of a deliberately arranged group of buildings that likely guided the design of the later Civic Center area.","period_of_significance":"1924","architect_builder":"Rice, Lilian Jenette","architectural_style":"Spanish Colonial Revival","criteria":["C"],"status_note":"Still in commercial use as business offices; interior altered in 1935 and iron window grilles and original windows removed.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:27.999757-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/91000940.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/91000940/e2eaa8bf91-800.webp","url_1600":"https://nationalhistoricalregister.com/media/91000940/e2eaa8bf91-1600.webp","licence":"Public domain","author":"Jack E.
