The City's Building Permits and Occupancy Inspection Information page says "The City of Ballwin is taking steps to adopt the 2024 International Building Codes," and that this "is an update from the 2015 standards the City currently uses." The codes recommended for adoption include the "2024 International Residential Code: Rules specifically for building new one- and two-family homes," and the page posts the City's proposed amendments in draft. The City's codified adopting section and its local amendments to the International Residential Code were not read for this record, so it gives no answer that depends on them.
