It sits among old Black Oak trees in a planned park.","why_significant":"The nomination argues the house is a good, well-preserved example of the American Foursquare style, with most of the style's characteristic features and good workmanship. A survey of the East Franklin planning area found it to be the only structure there with distinctive architectural merit, and comparison houses nearby had lost more integrity.","narrative":"Built in 1914, this two-story farmhouse in Elk Grove was ordered from a catalog by rancher William Ehrhardt in 1913. It arrived by rail, was hauled by wagon to his 160-acre ranch, and was assembled with help from two neighbors. The house follows the American Foursquare plan, a vernacular form of the Prairie style, with a box shape, four equal rooms on each floor, a low hipped roof with wide boxed eaves, and a full-width front porch on a brick base. Decoration is minimal. Original hardwood floors, plaster walls, a brick fireplace and many original windows survive, though the back porch and kitchen were altered later. A survey of the surrounding East Franklin planning area found it the only building with distinctive architectural merit and compared it favorably with other Foursquare houses nearby. It was a dwelling until 2001 and is now deteriorated, with roof damage and vandalism, but is planned for preservation on its original site within a new park among old Black Oaks.","period_of_significance":"1914","architect_builder":"Builder: Ehrhardt, William","architectural_style":"Late 19th and Early 20th Century American Movements (American Foursquare, a subtype of Prairie style)","criteria":["C"],"status_note":"Used as a dwelling from 1914 to 2001; now deteriorated and needing structural and cosmetic repair, with vandalism damage, and slated to be preserved in a 1.9-acre park.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:29.790468-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/03000614.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/03000614/2440ae651b-800.webp","url_1600":"https://nationalhistoricalregister.com/media/03000614/2440ae651b-1600.webp","licence":"CC BY-SA 3.0","author":"Toyz1988","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Ehrhardt_House.jpg\" rel=\"noopener\">Toyz1988</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:Ehrhardt_House.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123860578","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q133441042"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/sacramento-county/ehrhardt-william-house-03000614/"}
