A gable-roofed garage stands at the rear of the lot.","why_significant":"The house is considered an excellent example of the dwellings built in Point Arena after the 1860s settlement period, with a larger side-gabled form but a strictly functional design. It is also one of the last buildings in town linked to the Iversen family, and its integrity is described as high.","narrative":"Iverson House is a one-story wood-frame home at 40 Iverson Avenue in Point Arena, Mendocino County, estimated to date from about 1875. It has horizontal wood siding, a side-facing gable roof with cornice returns, and a full-width shed-roofed porch. The front door is flanked by six-over-six double-hung windows with decorative shutters. A gable-roofed garage at the rear is not counted as contributing because it was built later than the house. The house was listed for its architecture. It represents the type of home built in Point Arena after the settlement period of the 1860s, keeping the side-facing gable of earlier dwellings while being larger, with rooms at the rear. Its design is plain and functional, with no ornamentation, and its integrity is high, though the porch may have replaced a smaller portico around 1930. Members of the Iversen family lived here for generations. Niels Iversen arrived in Point Arena in 1865 and became a prosperous merchant and hotel owner.","period_of_significance":"1875 (estimated)","architect_builder":"Unknown","architectural_style":"Greek Revival","criteria":["C"],"status_note":"Current use is residential, as a single dwelling.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:27.720718-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/90001353.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/90001353/3f7ee55fe4-800.webp","url_1600":"https://nationalhistoricalregister.com/media/90001353/3f7ee55fe4-1600.webp","licence":"CC BY-SA 3.0","author":"Frank Schulenburg","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Iverson_House,_Point_Arena.jpg\" rel=\"noopener\">Frank Schulenburg</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:Iverson_House,_Point_Arena.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123857658","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q56269396"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/mendocino-county/iverson-house-90001353/"}
