Iowa, Mills County Electrician Permit Regulations and County Ordinances for Unincorporated Areas

Mills County, Iowa, handles building permits for properties in unincorporated areas through its Building & Zoning Department. For electrical permits specifically, after July 16, 2021, these must be obtained from the Iowa Department of Public Safety, State Fire Marshall Division, Electrical Bureau, rather than the county. The county will not collect separate electrical permit fees or issue electrical permits directly. However, the county does require proof of electrical inspections and a Contractor Certificate of Compliance for final permit approval and issuance of a Certificate of Occupancy. The county building codes include the State National Electrical Code 2020.

Iowa Electrician Legislation, Codes, and Guidelines

Iowa State Building Codes and Legislation for Electricians

In Iowa, the regulation of electricians and electrical work falls under the purview of the Iowa Electrical Examining Board, which operates under the Department of Inspections, Appeals, and Licensing (DIAL). The state adopts specific editions of the National Electrical Code (NEC) as its standard for electrical installations.

As of July 1, 2025, Iowa will officially inspect electrical permits to the 2023 National Electrical Code (NEC). Permits purchased before this date will be inspected under the 2020 NEC. There have been legislative updates, such as SF2374, which proposed adopting the 2023 NEC with specific modifications, including changes to GFCI and AFCI protection requirements.

Historically, Iowa has adopted various editions of the NEC. For instance, the 2020 NEC became effective on April 1, 2021, with time-limited amendments. Prior to that, the 2017 NEC was in effect, and some sources indicate earlier adoptions of the 1990 NEC for specific regulations.

The Iowa Electrical Examining Board is responsible for setting these standards and overseeing the licensing and regulation of electricians. Electricians in Iowa must be licensed, with pathways to obtain journeyman and master electrician licenses requiring specific education and work experience. Continuing education is also mandated for license renewal, with specific requirements for studying the latest NEC.
