The International Building Code references APA, Plywood Design Specification 4—Design & Fabrication of Plywood Sandwich Panels for the design of SIPs.<ref>APA. Plywood Design Specification Supplement 4: Design and Fabrication of Plywood Sandwich Panels. Document U814-H. March 1990.</ref> This document addressed the basic engineering mechanics of SIPs but does not provide design properties for the panels provided by any specific manufacturer. In 2007, prescriptive design provisions for OSB faced SIPs were first introduced in the 2006 International Residential Code. These provisions provide guidance on the use of SIPs as walls panels only.

Aside from these non-proprietary standards, the SIP industry has relied heavily on proprietary code evaluation reports. In early 2009, SIPA partnered with [https://www.icc-nta.org/ ICC NTA, LLC], a third-party product evaluation certification agency, to produce the first industry wide code report which is available to all SIPA members who qualify. Unlike previous code reports, the prescriptive provisions provided in the SIPA code report are derived from an engineering design methodology which permits the design professional to consider loading conditions not addressed in the code report.<ref name="Using NTA Listing Report Data 2009"/><ref>[https://online.ntainc.com/public/certification/reports/report/?ID=7ae06f12-ef2a-4c8c-b5bb-95c32ae20839 SIPA code report] {{Webarchive|url=https://web.archive.org/web/20090620063935/http://www.sips.org/content/index.cfm?pageId=272 |date=2009-06-20 }} SIPA code report requirements at SIPA web site</ref>
