Scott County Plumbing Permit Requirements
Scott County, Iowa, through its Planning & Development department, handles building and safety regulations, including plumbing permits, for unincorporated areas.
For properties in unincorporated areas of Scott County, a plumbing permit is required for any work that involves altering, repairing, replacing, or installing any part of the plumbing system, including water heaters. Sub-contractors performing plumbing work are responsible for obtaining their own construction permits.
The permit application process requires a completed application form, two sets of full-size building plans, a site plan, a RESCheck report, and zoning approval. Fees for permits are based on the cost of the work and are outlined in the Scott County Fee Schedule. Payment can be made online via credit card or by check.
Scott County has adopted various construction codes, including the International Residential Code and the Uniform Plumbing Code, as amended by the State of Iowa.
Permits become invalid if work is not commenced within 180 days of issuance or is suspended for 180 days. All work must be completed within one year of the issuance date, though extensions may be granted.

State Statutes and Plumbing Codes
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. Local jurisdictions in Iowa are prohibited from adopting other plumbing codes, though they may adopt additional amendments provided those requirements are stricter than the state-adopted code.

The board operates under the Iowa Department of Inspections, Appeals, and Licensing (DIAL). 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.
