It was constructed in 1896 and has a full basement.","why_significant":"The nomination argues the building is a locally significant example of turn-of-the-century commercial architecture. Its design combined traditional heavy and light timber framing with an external expression of steel frame technology and reduced Classical Revival and Commercial style ornamentation, illustrating a transitional stage of local commercial construction. It survives with excellent integrity.","narrative":"Four-story brick commercial building across from Courthouse Square in Scranton, built in 1896 and first known as the P.P. Carter Building. Its rectangular plan measures 45 feet wide on Adams Avenue and 150 feet deep on Linden Street, with running bond brick walls, metal ornamentation at pier capitals, parapets and entablatures, and large glazed storefronts at sidewalk level. The building is regarded as a locally significant example of late nineteenth-century commercial design that combined traditional timber framing with an external expression of steel frame technology and restrained Classical Revival detailing. It housed a printing company, a sweet shop, a bank and trust company, a dance studio, an advertising agency, a bus terminal and a newsstand. In 1928 it became known as Ad-Lin Hall. A 1985 rehabilitation cleaned the brick, repointed mortar joints, restored storefronts and retained the fourth-floor auditorium's pressed metal ceiling, leaving the building with its significant features largely intact.","period_of_significance":"1896-1897","architect_builder":null,"architectural_style":"Classical Revival/Commercial Style","criteria":["C"],"status_note":"Rehabilitated in 1985 following the Secretary of the Interior's Standards for Rehabilitation, with the building continuing in commercial and auditorium use.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:33.538029-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/87001969.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/87001969/e5a527b0e1-800.webp","url_1600":"https://nationalhistoricalregister.com/media/87001969/e5a527b0e1-1600.webp","licence":"CC0","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Ad-Lin_bldg_Scranton_PA.JPG\" rel=\"noopener\">Smallbones</a>, <a href=\"http://creativecommons.org/publicdomain/zero/1.0/deed.en\" rel=\"license noopener\">CC0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Ad-Lin_bldg_Scranton_PA.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71998085","wikipedia":"https://en.wikipedia.org/wiki/Ad-Lin_Building","wikidata":"https://www.wikidata.org/wiki/Q4678068"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/lackawanna-county/ad-lin-building-87001969/"}
