Union County, Iowa Electrician Permit Requirements
Union County, Iowa, does not appear to have its own distinct building and safety division for issuing electrician permits. Instead, electrical licensing and regulation are handled at the state level by the Iowa Department of Inspections, Appeals, & Licensing (DIAL) and the Iowa Electrical Examining Board.
For properties in unincorporated areas of Union County, the same state-level licensing requirements for electricians apply. There is no indication of separate county-level permitting processes for electrical work in these areas. However, Union County does have a Utility Permit Application process for work within the county's right-of-way, which may include electrical installations. This permit requires compliance with specific depth requirements for cables, a notice to proceed, and proof of insurance.
To perform electrical work in Iowa, individuals must hold a valid state-issued license. The state offers various types of licenses, including Apprentice Electrician, Residential Electrician, Journeyman Electrician (Class A and B), and Master Electrician (Class A and B).
Key requirements for obtaining an electrical license in Iowa generally include:
- Being at least 18 years old.
- Holding a high school diploma or GED.
- Completing classroom training (except for Unclassified Workers).
- Acquiring progressive work experience.
- Passing a state-administered examination (exceptions apply for certain license types).
- Paying applicable fees.
- Applying through the Iowa Department of Public Safety.
Specific requirements for each license type, such as the number of work experience hours and examination details, vary. For instance, Class A Journeyman and Master licenses typically require passing state exams, while Class B licenses often rely on extensive work experience.
Electrical contractors in Iowa must also be licensed and typically need to employ or be a master-level license holder. They are generally required to carry general liability insurance of at least $1 million and workers' compensation insurance if they have employees.

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.
