The Gypsum Association maintains evaluation reports issued by code bodies or jurisdictions, specifically the International Code Council (ICC Evaluation Service, Inc.), and the City of Los Angeles. These reports demonstrate code compliance and acceptance of specific gypsum materials and systems. In addition, this page allows you to access information about specific building code compliance issues that may arise from time to time.

International Building Code

Published by International Code Council, Washington, DC

Footnotes m to Table 721.1(1); o to Table 721.1(2); and q to Table 721.1(3) of the 2012 International Building Code state “Generic fire-resistance ratings (those not designated as PROPRIETARY in the listing) in the GA-600 shall be accepted as if herein listed. Table 2508.1 of the 2012 International Building Code lists “GA-216″ (Specification: Application and Finishing of Gypsum Panel Products) as a reference standard to be followed in the application and finishing of gypsum board.

NOTE: ICC has issued an errata to Section 403.2.2.1 of the 2021 International Building Code. This errata clarifies that only the exterior walls of interior exit stairways and elevator hoistway enclosures need to meet a Soft Body Impact Classification Level of 2. The code had incorrectly implied both the inside and outside needed to meet this criteria. Download the errata.
