Idaho Roofing Legislation, Codes, and Guidelines

State Statutes and Adopted Building Codes

The State of Idaho adopts building codes through state statute, with specific editions and amendments finalized through the legislative process. As of the most recent state-level guidance, Idaho utilizes the International Code Council (ICC) family of codes, including the 2018 International Building Code (IBC) and the 2018 International Residential Code (IRC). These are implemented with specific Idaho-approved amendments. For residential roofing, the requirements are primarily found within the 2018 IRC (specifically Chapter 9, "Roof Assemblies") as modified by the Idaho Residential Code amendments.

Primary State Board and Agencies

The primary agency responsible for the administration and oversight of building codes in Idaho is the Division of Occupational and Professional Licenses (DOPL), specifically through its Building, Construction & Real Estate Bureau. The Idaho Building Code Board is the body tasked with overseeing the adoption and application of these building standards. Local jurisdictions in Idaho may adopt additional codes or local amendments, provided they are no less stringent than the requirements established by the state.
