Low-voltage licensing
Iowa
Iowa requires state Electrical Contractor licensing through the Iowa Electrical Examining Board. The state has a specific Class B Special Electrician category for low-voltage / limited-energy work, and a Class C Special Electrician for fire alarm. Both require a designated master license-holder for the business.

Common pitfalls
Mistakes we see installers make when navigating Iowa licensing.
- Class B (low-voltage) and Class C (fire alarm) are separate licenses with separate exams. Doing both scopes requires both licenses.
- Triennial (3-year) renewal cycle requires continuing education; missing CE invalidates the renewal application.
- Des Moines and Cedar Rapids each have local permit and inspection requirements layered on top of state licensing.
