Ohio Construction Industry Licensing Board (OCILB), Division of Industrial Compliance, Ohio Department of Commerce administers electrical contractor licensing in Ohio. Every figure below is verified against the board’s own official pages and dated. Who must personally hold a credential — the contractor, the business, or the individual worker — is set out under Requirements.
What it’s called
In Ohio the state credential is an electrical contractor license, issued by the Ohio Construction Industry Licensing Board (OCILB) for commercial work — not an individual electrician license. Residential electrical licensing is handled by municipalities. A search for an “Ohio electrician license” maps to the state contractor license (commercial) or a local license (residential). “Electrician license” and “journeyman electrician license” are common informal names for these.
License types & fees
| Type | Experience | Exam | Fee |
|---|---|---|---|
| Electrical Contractor (commercial) | Must have been a tradesperson in the electrical trade for not less than five (5) years immediately prior to the date of application (alternatives: registered Ohio professional engineer with 3 years construction-industry business experience in the trade, or 5 years as an Ohio government inspector in the trade). | Two-part exam: electrical trade part + business and law part; 70% required on each part (OAC 4101:16-2-03). | $25 examination application + $25 license issuance |
Who does NOT need this license — exemptions
Ohio’s state credential is the OCILB (commercial) Electrical Contractor license under ORC Chapter 4740, and its biggest carve-out is built into the definitions rather than an ’exemptions’ section. ORC 4740.01(F) defines ‘construction project’ to exclude ‘an industrialized unit or a residential building as defined in section 3781.06 of the Revised Code’ — and ORC 3781.06(C)(9) defines a residential building as ‘a one-family, two-family, or three-family dwelling house, and any accessory structure incidental to that dwelling house’ (accessory structures include garages, porches, and screened-in patios). Electrical work on those residential buildings is therefore outside the state license requirement entirely; the Ohio Department of Commerce states plainly that ‘residential contractors are not required to be licensed by the state,’ while noting that ’local building departments throughout Ohio may have their own verification or licensing requirements’ — many municipalities license residential electrical contractors and journeymen locally. Second, individual electricians are exempt by design: Ohio licenses only the CONTRACTOR (the individual holding out as responsible for the means, method, and manner of the work, per ORC 4740.01(B)); a ’tradesperson’ — an individual employed by a contractor who works ‘without assuming responsibility for the means, method, or manner’ of the work (ORC 4740.01(E)) — needs no state license, though ORC 4740.12(B)(2) preserves the power of political subdivisions to register tradespersons. ORC 4740.131 likewise permits contractors to use employees leased from professional employer organizations or temp agencies under the contractor’s direct supervision. Third, ORC 4740.13(D) is a low-voltage carve-out: a person is not an electrical contractor subject to licensure for work limited to constructing, improving, renovating, repairing, testing, or maintaining fire alarm, burglar alarm, cabling, tele-data sound, communication, and landscape lighting and irrigation systems using less than fifty volts. Fourth, ORC 4740.13(C) lets a contractor licensed in another OCILB trade (HVAC, refrigeration, plumbing, hydronics) install, service, and maintain the related or interfaced control wiring for equipment and devices related to that license, provided the control wiring is less than twenty-five volts — the HVAC-incidental-wiring exemption.

(OAC 4101:16-2-09; OCILB Examination Application)
Exam
Two-part, computer-based exam administered by an approved testing agency (candidates receive a PSI Candidate Information Bulletin): (1) a part specific to the electrical trade, and (2) a business and law part. A score of 70% is required on each part; a passed business-and-law part remains valid for 3 years. Offered at least four times per year at sites throughout Ohio and the U.S. (OAC 4101:16-2-03; OCILB Examination Application).
Renewal & continuing education
Annual, with a triennial (3-year) renewal option; a licensee renews each year by certifying $500,000 liability insurance, paying the renewal fee, and meeting continuing-education requirements (OAC 4101:16-2-06 and 4101:16-2-07). For a licensee holding only an electrical license: 10 classroom hours of approved continuing education per year — at least 5 hours of electrical code approved by the electrical section, plus 5 hours in an approved health & safety, business, or technology course (OAC 4101:16-2-08).
