General FAQs

Where can I find a copy of the current energy code?

Idaho's Energy Code is based on the International Energy Conservation Code. The IECC is a "comprehensive energy conservation code [that] establishes minimum regulations for energy-efficient buildings using prescriptive and performance-related provisions." A copy of the energy code can be viewed on the International Code Council website. 

Current building codes and the Idaho amendments to the IECC are included in the Idaho Statutes and Administrative Rules
