What ICC NTA does

ICC NTA is a third-party testing, inspection, certification, and engineering services provider for the building products and off-site construction industries. Founded in 1976 as NTA, Inc., a family-owned company in Nappanee, Indiana, the firm was acquired by the International Code Council (ICC) in July 2019 and now operates as a wholly-owned subsidiary branded ICC NTA, LLC. The company serves building product manufacturers, off-site/modular builders, HUD-regulated manufactured housing participants, code officials, and residential and commercial builders across more than 40 U.S. states and Canada, employing 101–250 staff across offices and laboratories in Nappanee, Indiana and Bryan, Texas.

ICC NTA's service portfolio comprises three integrated core lines — third-party plan review, product evaluation, and testing and certification — supplemented by specialized verticals covering off-site construction services, HUD services (DAPIA and IPIA approvals), inspections and quality audits, engineering, CAD, and forensics. Testing is performed in A2LA-accredited laboratories operating under ISO/IEC 17025, 17020, and 17065, covering more than 300 standard test methods across ASTM, NFPA, AAMA, UL, CSA, EN, ISO, and government standards. The new 27,000 sq ft Bryan, Texas facility, opened in phases beginning Fall 2020, anchors the company's large- and intermediate-scale fire testing capabilities, including ASTM E84, NFPA 285, ASTM E119, and UL 723.

ICC NTA generates revenue primarily through professional services engagements priced per project on a quote basis, including testing, certification, inspection, engineering, and plan review work. Distribution is direct via project-based engagement and approved-provider status across 40+ state and Canadian jurisdictions, supplemented by industry trade show participation (NAHB International Builders' Show, Manufactured Housing Show, World of Modular, SIPA Annual Meeting, EPS Expo), educational blog and video content, and a subscription-based state code-update notification service. The company holds regulatory designations that include HUD DAPIA and IPIA approvals (a designation held by only five private companies), Standards Council of Canada Certification Body recognition, and USDA FmHA Recognized Code Authority status.
