Code Development

As technology and building science continue to develop, their advancements are often reflected in the International Code Council (ICC) series of model codes. NAHB reviews the codes and identifies changes that either have a negative impact on the building industry and home buyers or that will save builders time and/or expenses during construction.

NAHB staff offers expert advice and assistance in code adoptions locally as well. Contact a staff liaison.

The ICC code development process is fair and equitable, designed to create the best and most comprehensive set of building codes available. However, it is critical to ensure that impractical and biased code change proposals are not approved in the next edition of the building codes. This can only be done if home builders, remodelers and their trade partners step up to keep housing safe and affordable for home buyers.

The final decision makers are government officials that have been validated by ICC. This group is primarily made up of building code officials. NAHB encourages all members to maintain productive relationships with their local building code officials and ensure they are eligible to vote for the next editions of the International Code Council’s family of model codes.

Here is the four-step process to make sure that happens:

  • Build relationships with your local code officials
  • Urge your code officials to participate in the ICC code development process
  • Seek opportunities to discuss building codes with your local code officials
  • Champion NAHB positions on code change proposals with your code officials

As the hearings draw closer, NAHB will post resources to help members promote cost-effective building codes.

The National Association of Home Builders has developed a High Priority Voting Guide to address the 15 most significant proposals which will impact the housing industry. NAHB urges all ICC Governmental Member Voting Representatives to support the housing industry for these critical proposals. The voting guide will help provide the home building industry with the ability to construct safe and affordable homes in the future. NAHB has also developed a Comprehensive Voting Guide which addresses all Group A proposals that we believe will impact the industry.
