State Statutes and Adopted Codes
The State of Iowa adopts model building codes to establish minimum safety and performance standards for construction, including HVAC systems. These adoptions are codified through the Iowa Administrative Code. As of recent updates, the state has adopted the following primary model codes:
- International Building Code (IBC): 2024 edition.
- International Residential Code (IRC): 2024 edition.
- International Existing Building Code (IEBC): 2024 edition.
- International Energy Conservation Code (IECC): 2012 edition.

It is important to note that Iowa Code Chapter 103A allows local jurisdictions (cities and counties) to adopt and enforce their own building codes, provided they are not less restrictive than the state-level standards. Consequently, contractors and designers must verify specific requirements with the local Authority Having Jurisdiction (AHJ) in addition to state-level mandates.
