The following statewide building codes and regulations apply universally to all jurisdictions within Kansas:

State-Level Building Codes and HVAC Legislation in Kansas
Kansas does not have a mandatory, statewide building code. Under the state's "Home Rule" authority, the responsibility for the adoption and enforcement of building codes—including those governing HVAC systems—lies entirely with individual cities and counties. Consequently, there is no single "Kansas Building Code," and regulations can vary significantly from one jurisdiction to another.
Because there is no statewide code, there is no single state agency that sets or enforces building standards for private construction. Local jurisdictions (cities and counties) act as the Authority Having Jurisdiction (AHJ) and determine which model codes to adopt, such as the International Mechanical Code (IMC), International Residential Code (IRC), or International Building Code (IBC), and whether to include local amendments. Contractors and design professionals must verify the specific code requirements and local ordinances with the building department in the jurisdiction where the project is located.
While the state does not regulate private building codes, the Kansas Department of Administration (Design, Construction & Compliance) is responsible for enforcing building codes and standards for projects on State of Kansas-owned property.
