Iowa, Montgomery County Plumbing Permit Regulations and County Ordinances for Unincorporated Areas
Montgomery County, Iowa, does not appear to have a dedicated "Building & Safety Division" at the county level for plumbing permits. Instead, permitting and code enforcement for unincorporated areas are typically handled at the state level or by specific county departments responsible for zoning and development. Iowa has a statewide plumbing code, which is based on the Uniform Plumbing Code (UPC), with the latest adopted version being the 2024 UPC.
Plumbing Permit Requirements in Unincorporated Areas
For properties in unincorporated areas of Montgomery County, Iowa, plumbing work must comply with the Iowa State Plumbing Code. Local ordinances may impose stricter standards, but not lower ones. The Iowa Plumbing Code applies to plumbing in buildings or on premises within cities and also to those outside city limits if they are connected to a municipal water or wastewater system.
Plumbing permits are generally required for new construction, alterations, additions, and repairs. Plumbing plans are typically required as part of the permit application. Licensed contractors are usually required to perform plumbing work.
It is advisable to contact the Montgomery County Planning & Zoning Department or a similar county office to confirm the specific permit application process and any local requirements for unincorporated areas.

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.
