Low-voltage licensing
Ohio
Ohio requires Electrical Contractor licensing through the Construction Industry Licensing Board (CILB), Ohio Construction Industry Examining Board. The Electrical Contractor classification covers all electrical including low-voltage. Some specialty work (HVAC, refrigeration, hydronics) has separate licensing; low-voltage is included under electrical.

Mistakes we see installers make when navigating Ohio licensing.
- Ohio's electrical contractor license is state-level but most cities (Columbus, Cleveland, Cincinnati, Toledo, Akron) also require local contractor registration and permits.
- The qualifying individual must be a W-2 employee or officer; cannot be a 1099 contractor borrowed across multiple businesses.
- Annual renewal with continuing-education hours required.
