Up-To-Date Building Codes Support Safe, Sustainable and Resilient Communities

Building codes represent a highly cost-effective strategy to help protect communities from the risks posed by natural and man-made events. The Congressionally-established National Institute of Building Sciences (NIBS) found that adopting and enforcing the 2018 International Building Code (IBC) and International Residential Code (IRC) provide communities with an $11 benefit for every $1 invested. The resources provided here can help you make sure your community captures these benefits while preventing injuries, deaths and property loss.

How Do States or Localities Adopt Building Codes?

The process for adoption at the state and local level varies, but typically allows for some level of public engagement. Learn how states adopt the International Codes (I-Codes). Sample ordinances are available to help communities get started in the adoption process.

How are Building Codes Developed?

The I-Codes are the most widely used and adopted set of building safety codes in the world. These model codes developed through a consensus process organized by the International Code Council that allows all interested parties to recommend changes. The final outcomes are voted on by state and local government officials that are charged with protecting health, safety and welfare in their communities. The I-Codes are updated every three years. See the infographics on the ICC Code Development Process.
