Iowa, Story County Plumbing Permit Regulations and County Ordinances for Unincorporated Areas
Story County Plumbing Permit Requirements
Story County, Iowa, requires permits for most construction and changes in land or building use, particularly in unincorporated areas. While the county's Planning & Development Department handles zoning permits and land use regulations for unincorporated areas, plumbing-specific permits are generally managed at the state level or by specific municipalities within the county. It's crucial to distinguish between county-level zoning and state or city-level trade permits for plumbing work.
County Jurisdiction and Unincorporated Areas
The Story County Planning & Development Department oversees zoning and land development regulations for all unincorporated areas of the county. This means permits are generally required for most structures, including new construction, fences, decks, and signs, to ensure compliance with zoning ordinances and setbacks.
Plumbing Permit Specifics
Story County itself does not appear to issue plumbing permits directly. Instead, electrical, mechanical, and plumbing work often requires a "trade permit." For properties within incorporated cities like Story City, a trade permit is necessary for all plumbing work not considered cosmetic. Homeowners may be able to pull their own trade permit if they reside on the property and have lived there for over six months, otherwise, a licensed contractor must obtain the permit.
For electrical work, permits and inspections are handled by the State of Iowa, not Story County.
It is essential to contact the relevant city or township authorities, or the State of Iowa Electrical Permit office, depending on the property's location, to determine the exact requirements for plumbing permits and inspections. The Story County Planning and Development Department can be contacted for guidance on zoning and general building permits.

Iowa Plumbing Legislation, Codes, and Guidelines
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. The state has adopted the 2024 edition of the Uniform Plumbing Code (UPC), published by the International Association of Plumbing and Mechanical Officials (IAPMO), as the base technical standard. 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.
Regulatory Board and Agencies
The primary state entity responsible for the regulation and licensing of plumbing professionals is the Iowa Plumbing and Mechanical Systems Board (PMSB). 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.
