The National Park Service built it in 1929 for $16,000.","why_significant":"The nomination calls it an outstanding local example of the 'Rustic' style used by National Park Service architects in the 1920s and 1930s, a style described as increasingly rare. It is also locally significant in conservation, as the building from which the park has been administered and maintained since 1929.","narrative":"Park Headquarters at Lassen Volcanic National Park is a two-story wood frame building measuring 30 by 60 feet, with a two-story front wing and a covered rear porch. Built by the National Park Service in 1929 for $16,000, it has a stone-veneered concrete foundation, dark brown horizontal siding, white trim and a steeply pitched shake roof designed to shed heavy snow. A roof overhang shelters the recessed front doorway. Inside are ten rooms, including offices for the superintendent, chief ranger and naturalist. It was listed for two reasons. It is regarded as an excellent local example of the Rustic style, which aimed to keep buildings subordinate to their setting by using native wood and stone. It has also been the center of park administration and maintenance since 1929. The nomination notes a drainage problem causing dampness and decay, and recommends preservation with in-kind repairs.","period_of_significance":"1929","architect_builder":"National Park Service","architectural_style":"Rustic","criteria":[],"status_note":"Occupied and in good condition, though water leaks through the concrete foundation into the basement and has caused warping and rotting of siding and porch columns.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:31.274208-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/06000490.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/06000490/655474821c-800.webp","url_1600":"https://nationalhistoricalregister.com/media/06000490/655474821c-1600.webp","licence":"Public domain","author":"National Park Service inventory","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Lassen_NP_headquarters.jpg\" rel=\"noopener\">National Park Service inventory</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Lassen_NP_headquarters.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123862190","wikipedia":"https://en.wikipedia.org/wiki/Park_Headquarters,_Lassen_Volcanic_National_Park","wikidata":"https://www.wikidata.org/wiki/Q7137764"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/tehama-county/park-headquarters-lassen-volcanic-national-park-06000490/"}
