Background: Due to its history of strong local government, Missouri does not have a mandatory statewide energy code. However, all local jurisdictions except class III counties have the right to adopt an energy code. As expected, this system creates a sometimes confusing patchwork of different codes throughout the state.
Regardless of the system in place, the bottom line is that many jurisdictions in Missouri still don’t have an energy code—meaning that many residents do not receive the benefits of energy-efficient construction.
Local Adoption: For more, view the BCAP Missouri Gap Analysis Report, starting with pages 19-22.
It is typical for Missouri communities to adopt codes on a 6-year cycle rather than the 3-year code development cycle for ICC. It is also typical for communities to follow the code adoption of surrounding communities. These adoption practices have developed two trends in Missouri; eastern Missouri communities are generally on the 2003 I-Codes and are moving/have moved to the 2009 I-Codes and western Missouri communities are generally on the 2006 I-Codes and are moving to the 2012 I-Codes.
