Next Update Cycle (amendment opportunities):

No current plan to update to 2015 “I” Codes. No apparent adoption of the provisions contained in the 2015 IRC under Section R302.13.

Additional Notes:

St. Louis County is considering adoption of the 2015 IECC. In Missouri, only the General Assembly is authorized to enact legislation to establish statewide building construction regulations and/or authorize a state agency to do so. However, there currently is no state regulatory agency authorized to promulgate, adopt, or update construction codes on a statewide basis.
