It holds 285 principal buildings and 211 secondary structures dating from about 1850 to 1950.","why_significant":"The district shows Elgin's northward residential growth from the 1850s to the mid-20th century, with a broad range of architectural styles and house types. Douglas Avenue and Spring Street developed as homes for prominent citizens, and the district holds a large concentration of high-style houses. Growth was driven by the street car line, industry and new subdivisions.","narrative":"Spring Street and Douglas Avenue in Elgin's Northeast Neighborhood form a residential district of 285 principal buildings and 211 secondary structures, mostly built between 1850 and 1950. The district lies east of the Fox River and north of downtown, running from Kimball Street to the river bluff at River Bluff Road. Its houses trace the city's northward growth: pre-Civil War Greek Revival and Italianate homes at the south end, Stick, Queen Anne and Shingle Style houses from the boom years before 1900, and Colonial Revival, Tudor, Craftsman and Prairie designs farther north. A street car line opened on Douglas Avenue in 1881, and subdivisions for factory workers and local leaders spurred most construction between the 1880s and 1930s. Prominent Elgin architects designed some houses. Although siding and porch changes have affected some buildings, many keep their original detailing, and recent rehabilitation has strengthened the district's historic character. Elgin's industrial growth is reflected in the housing.","period_of_significance":"1850-1950","architect_builder":"Smith Hoag and Gilbert Turnbull (architects of individual houses); other architects and builders named for individual buildings","architectural_style":"Bungalow/Craftsman, Classical Revival, Colonial Revival, Italianate, Mission/Spanish Colonial Revival, Prairie School, Queen Anne, Shingle Style, Stick/Eastlake, Tudor Revival","criteria":[],"status_note":"Largely residential and still in use; many buildings have had siding, porch and window alterations, though restoration and rehabilitation have increased in the past decade.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:37.301417-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/6/8931/28893106/content/electronic-records/rg-079/NPS_IL/00000410.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/00000410/cfb3d7e9c6-800.webp","url_1600":"https://nationalhistoricalregister.com/media/00000410/cfb3d7e9c6-1600.webp","licence":"Public domain","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Elgin_Spring_Douglass_HD.JPG\" rel=\"noopener\">Smallbones</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Elgin_Spring_Douglass_HD.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/28893106","wikipedia":"https://en.wikipedia.org/wiki/Spring%E2%80%93Douglas_Historic_District","wikidata":"https://www.wikidata.org/wiki/Q7581284"},"indexable":true,"url":"https://nationalhistoricalregister.com/illinois/kane-county/spring-douglas-historic-district-00000410/"}
