It is also tied to the early agricultural development of the Kings River Thermal Tract. Its significance is local.","narrative":"Perched on a knoll above Tivy Valley near Sanger, this one-and-a-half story wood frame house was built in 1910 for Bertrand L. and Cornelia Stoner. Locals call it the Stoner Mansion. It is a large California Bungalow with a low gable roof, broad eaves, scribed barge boards, cedar-shingled upper walls, three-tier clapboard below, and a covered porch and tall fireplace made of river rock from the nearby Kings River. Fourteen rooms hold roughly 4,000 square feet, and a matching 1910 barn stands to the southeast. Restoration in the early 1980s replaced the roof, gutters, kitchen cabinets and plaster while keeping original windows and hardware. The nomination presents the house as the finest example of its type in the valley and the largest of its older homes. It also links the Stoners to the Kings River Thermal Tract, where early settlers turned dry cattle and grain land into productive orchards and vineyards.","period_of_significance":"1900-1999 (specific date 1910)","architect_builder":null,"architectural_style":"California Bungalow","criteria":[],"status_note":"Condition listed as excellent and restored; used as a private residence, with the form's use boxes also marking agriculture and unoccupied.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:28.295626-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/85003145.pdf"},"photo":null,"district":{"nrhp_refnum":"16000468","name":"Big Creek Hydroelectric System Historic District","url":"https://nationalhistoricalregister.com/districts/california/big-creek-hydroelectric-system-historic-district-16000468/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123858701","wikipedia":"https://en.wikipedia.org/wiki/Stoner_House","wikidata":"https://www.wikidata.org/wiki/Q85803587"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/fresno-county/stoner-house-85003145/"}
