The state of Iowa regulates plumbing installations through the Iowa State Plumbing Code, which is established under the authority of Iowa Code Chapter 105.

This adoption is codified in the Iowa Administrative Code (specifically Chapter 25), which includes state-specific amendments to the model code.

The PMSB is tasked with licensing individuals at various levels—including apprentices, journeypersons, masters, and contractors—and overseeing the enforcement of state laws and technical standards related to plumbing and mechanical systems.
