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:

Consequently, contractors and designers must verify specific requirements with the local Authority Having Jurisdiction (AHJ) in addition to state-level mandates.
