The architect and builder are unknown.","why_significant":"The nomination argues the house is significant under Criterion A for representing residential development along East Broad Street, then one of the most fashionable streets in Columbus. It is also significant under Criterion C as a good example of early 20th century residential architecture in the Colonial Revival style.","narrative":"Built around 1912 at 973 East Broad Street in Columbus, this 2-1/2 story tan brick house with red mortar reflects the Colonial Revival style. Classical details include a Doric-columned porch with full entablature across the north facade, bracketed eaves, a cornice with modillions, and a single-sash glazed entrance with sidelights. A hipped roof rises to a large central front dormer with four double-hung windows, and a one-story addition extends from the rear. When it was built, East Broad Street was regarded as one of the most fashionable addresses in Columbus, home to many prominent businessmen and professionals. Carl G. Heyne, president of the American Cash Register Manufacturing Company, lived here from 1912 to 1914. Charles Zimmerman, manager of Ohio Auto Sales, moved in during 1918, and his widow remained until the early 1940s. The house was listed for its role in the street's residential development and as a good example of early twentieth-century residential design.","period_of_significance":null,"architect_builder":null,"architectural_style":"Colonial Revival","criteria":["A","C"],"status_note":"Listed as a residence in good interior and exterior condition, with a one-story rear addition.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:14.336456-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/86003450.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/86003450/28c7686b15-800.webp","url_1600":"https://nationalhistoricalregister.com/media/86003450/28c7686b15-1600.webp","licence":"Public domain","author":"Nyttend","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Heyne-Zimmerman_House.jpg\" rel=\"noopener\">Nyttend</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Heyne-Zimmerman_House.jpg"},"district":{"nrhp_refnum":"78002063","name":"Columbus Near East Side District","url":"https://nationalhistoricalregister.com/districts/ohio/columbus-near-east-side-district-78002063/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71985238","wikipedia":"https://en.wikipedia.org/wiki/Heyne-Zimmerman_House","wikidata":"https://www.wikidata.org/wiki/Q105081684"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/franklin-county/heyne-zimmerman-house-86003450/"}
