State-level license requiredLast verified May 23, 2026

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.

Common pitfalls

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.
