Ohio Electrical Contractor License Requirements

Ohio's state electrical license is a commercial electrical contractor license issued by the Ohio Construction Industry Licensing Board (OCILB). Ohio doesn't issue a state journeyman or residential electrician license. Worker and residential rules are set locally.

What Ohio requires

Last verified October 1, 2026, against ORC Chapter 4740, OAC 4101:16, the OCILB application (rev. 9/2025) and the PSI candidate bulletin.

Is this the license you need?

You need the state license if you run, bid or take responsibility for electrical work on commercial construction projects in Ohio. The law defines a "contractor" as the person or company that controls the means, method and manner of the work and presents itself as qualified to do it (ORC 4740.01). Nobody may act as, or claim to be, a licensed electrical contractor without holding or being assigned the license (ORC 4740.13(A)).

Three limits change the answer for a lot of people:

• Residential work is outside the state definition. A "construction project" under Chapter 4740 excludes residential buildings. Those are one-, two- and three-family homes plus attached garages and porches (ORC 4740.01(F); ORC 3781.06(C)). Local building departments regulate residential contractors, and the law lets them require the state commercial license for residential work (OCILB).
• Employees can work under the contractor's license; independent contracting is different. A tradesperson employed by a licensed contractor can perform covered work under that contractor's responsibility. But a tax form by itself does not decide licensing status. If another individual or company independently acts as an electrical contractor on a Chapter 4740 construction project, that contractor must hold or be assigned the required license (ORC 4740.01; ORC 4740.13(A)).
• Some low-voltage work is exempt. Work limited to fire or burglar alarm, cabling, tele-data, sound, communication, or landscape lighting and irrigation systems under 50 volts doesn't require the electrical contractor license (ORC 4740.13(D)).

Not every city has every item in the right-hand column. Check the building department where the job is.

Find your qualifying route

Pick the line that sounds like you, then read that route below. The OCILB Electrical Section decides whether your experience qualifies. This matches your situation to a published route, but it isn't an eligibility decision.

Route 1: Five years as an electrical tradesperson

This is the standard route. You need at least five years as a tradesperson in the electrical trade immediately before the date you file (ORC 4740.06(B)(3)).

Attach: five consecutive years of tax documents (W-2s, Schedule C or K-1), plus one of these (application; OCILB checklist):

Document caution: The current OCILB examination application, page 1 expressly lists W-2s or Schedule C. It does not expressly list K-1. Confirm K-1 acceptance with OCILB before relying on it as your tax-document evidence.

• At least one permit for each of the last five years, pulled by the licensed contractor you worked for. That contractor must be the employer shown on your tax documents.
• An active journeyman card in the electrical trade.
• A certificate of completion from an apprenticeship approved by Ohio or the U.S. Department of Labor.
• Certificates for 40 hours of non-duplicated code courses in the electrical trade from an OCILB-approved training agency. They must be taken live or virtually; self-guided or self-paced courses don't count for licensing purposes.

Watch out: sewer service, water service, gas service and drain-cleaning permits don't count. Permits are public record, so your local building department can pull them if your employer won't. The form also asks for the contractor license number you worked under for each job. It asks for a specific description of your duties.

Route 2: Owner, partner or employee of a licensed company

If you were a full-time owner, partner or employee of a licensed commercial electrical contracting company for the five years immediately before you apply, the board may accept that as qualifying experience (OAC 4101:16-2-01(H)(3)(c)).

Attach: your tax documents and proof of your role with the licensed company.

Watch out: office roles don't count. The rule excludes inventory worker, counter salesperson, manufacturer rep, purchasing agent, secretary, clerk and bookkeeper experience. It also excludes general-contractor experience that isn't directly electrical (OAC 4101:16-2-01(H)(3)(d)).

Route 3: Five years in the trade, but not the last five

The board may accept five years of electrical experience even when it isn't the five years right before you apply (OAC 4101:16-2-01(H)(3)(a)). The conditions:

• At least three of the five years must be construction work on commercial or residential projects in the electrical trade. Residential years can count here.
• Education programs other than an Ohio-approved apprenticeship can replace at most one year of the five.
• Your documents (tax records plus permits, a journeyman card, an apprenticeship certificate or 40 code hours) must show you spent a majority of the five years in the trade.

Route 4: Professional engineer

A currently registered professional engineer in Ohio qualifies with three years of business experience in the construction industry in the electrical trade (ORC 4740.06(B)(3)). An engineer not registered in Ohio needs five years of that business experience (OAC 4101:16-2-01(H)(3)(a)(iii)).

Attach: your Ohio PE certification and the experience records the current OCILB application requests.

Route 5: Ohio government inspector

Five years as an Ohio government inspector in the electrical trade is listed as acceptable experience (OAC 4101:16-2-01(H)(3)(b); application).

Route 6: Out-of-state license holder

If you hold a substantially similar electrical contractor license in another state, Ohio law gives you a separate route to the exams (ORC 4740.06(C)). This isn't reciprocity: you still take both Ohio exams. Use the out-of-state application and include:

• Proof of your out-of-state license, showing at least five years' experience, the license status and the license type.
• Proof of at least five permits (building authorizations) issued in the state where you're licensed.
• At least one tax return showing income from work under that license. The out-of-state form also asks for a W-2 if you aren't the owner.
• Proof your company is registered in Ohio as a foreign corporation or foreign LLC with a designated Ohio agent.

The board secretary must approve a complete application that meets these requirements within 30 days (ORC 4740.06(E)).

Route 7: Uniformed services

If your uniformed-service duties were substantially similar to electrical contracting work for at least three of the five years before you apply, you can qualify on that basis (ORC 4740.06(D)). For military veterans, the current OCILB examination application directs applicants to complete Question 11 and attach DD214 training records; it also lists training certificates, evaluations, a joint services transcript and a commanding-officer letter as possible supporting documents (application). Other qualifying uniformed-service applicants should use records that document the service and duties required by ORC 4740.06(D) and follow OCILB's current instructions. A complete application meeting the statutory route must be approved within 30 days.

Route 8: Reciprocity

Reciprocity can let a qualifying out-of-state license holder obtain the Ohio license without the Ohio trade examination when a written reciprocal agreement applies and OCILB finds the other state's requirements substantially equal (ORC 4740.08; OAC 4101:16-2-10). Some current state-specific reciprocity forms still require Ohio's Business & Law exam.

Ohio currently publishes electrical reciprocity application forms for these state routes:

The forms also impose state-specific license and testing conditions. For example, Kentucky requires both a Kentucky Master Electrician license and a Kentucky Contractor license earned by examination; Texas requires a Texas Master Electrician license held for at least one year; West Virginia requires both the West Virginia Master Electrician and Contractor Electrical licenses. Applicants who obtained the source-state credential by grandfathering or reciprocity may be ineligible for reciprocity and may instead have to use Ohio's examination route.

Use the current OCILB reciprocity form for your state rather than relying on an old state list. Current official examples include the Kentucky form, Louisiana form, Mississippi form, North Carolina form, South Carolina form, Tennessee form, Texas form, Virginia form and West Virginia form.

Licensed somewhere that does not have an applicable Ohio reciprocity agreement? Check Route 6, which is a separate path to qualify for Ohio's examinations.

Documents to gather before you apply

For Routes 1–5 (Routes 6–8 are listed above):

• Completed OCILB examination application, signed and notarized
• $25 application fee (check payable to "Treasurer, State of Ohio," or the card section on the form)
• Employment history for each employer: name, address, the contractor license number you worked under, dates, full- or part-time, and specific duties
• Five consecutive years of W-2s or Schedule C tax documents
• One supporting proof: five years of permits, a journeyman card, an apprenticeship certificate, or 40 live/webinar code hours
• Route-specific proof: Ohio PE certificate, inspector records, or DD214
• Proof of legal-alien status, if you aren't a U.S. citizen
• The name of the contracting company you'll assign the license to, and your position there

Mail it to Ohio Construction Industry Licensing Board, 6606 Tussing Road, P.O. Box 4009, Reynoldsburg, OH 43068-9009, or email it to OCILB@com.ohio.gov.

Don't get fingerprinted yet. The background check comes after approval, and it's only valid for one year (OAC 4101:16-2-02(L)).

How to get licensed, step by step

1. File the application. Send the notarized application, documents and $25 fee.
2. Wait for the board. OCILB's sections meet every other month to review new test applications (OCILB), so time your filing around that. You'll be notified by mail. If you're denied, the notice explains your right to a hearing (OAC 4101:16-2-02(J)).
3. Complete the background checks. After approval, get Ohio BCI and FBI fingerprint checks at a WebCheck location. Have the results sent directly to OCILB.
4. Schedule both exams with PSI. Your approval expires one year after your completed criminal records check (OAC 4101:16-2-03(G)). Book online at PSI's Ohio contractor page or call (855) 257-1621.
5. Pass both parts. You get a pass/fail report when you finish.
6. Apply for issuance. Within 12 months of passing, send the board (OAC 4101:16-2-02(K); OCILB):
   • your passing score for each exam;
   • a certificate of insurance for the company, listing OCILB as certificate holder (or a letter asking for inactive status);
   • the $25 license fee.
7. Register locally. Before you pull permits, check the city or county where you'll work.

The two exams

Both are computer-based, open-book PSI exams. You must score 70% on each part to pass (OAC 4101:16-2-03(D)). All figures below come from the PSI Ohio contractor bulletin, pp. 1–5.

Pretest questions don't count toward your score, but they do use your time. If every pretest item appears, you have about 2.2 minutes per question on both exams (240 ÷ 110 and 120 ÷ 55). You can go back and change answers while time remains. The on-screen tutorial, up to 15 minutes, isn't timed.

Electrical exam content

Business & Law exam content

What you can bring

Electrical exam: bring your own references. The allowed list is:

• The 2023 NFPA 70 National Electrical Code and/or the 2023 NEC Handbook. Either one is enough, or you can use both.
• Ugly's Electrical References, 2023.
• The Electrical Field Reference Handbook (revised for the 2008 NEC) or the IBEW-NECA Field Reference Book.

Code questions are based only on the listed edition. That applies even if your job sites use a different edition (NEC adoption by state).

Business & Law exam: the NASCLA Contractor's Guide to Business, Law, and Project Management – Ohio, 4th edition, is provided at the test center, and you can't mark it. You may also bring your own copy.

Rules for your books: you can highlight, underline and index (tab) them before exam day. You can't write in them, and you can't bring loose or attached papers. A candidate caught writing in a reference loses it and is reported to the department.

Calculator: PSI provides an on-screen calculator, and it's the only one you may use (calculator rules by exam).

ID: one valid, unexpired government photo ID with your signature, in the same legal name you registered under. Arrive 15 minutes early. Late arrivals may be turned away and lose the fee.

If you fail a part

You retake only the part you failed, paying PSI's fee again (OAC 4101:16-2-03(G)). You must wait at least 60 days between attempts. After five failed attempts, you have to file a new application before testing again (ORC 4740.06(G)). A failing score report includes diagnostic information to guide your review.

What it costs

Sources: OAC 4101:16-2-09; PSI bulletin, p. 1; OCILB.

OCILB's own fees for a first license come to $50 ($25 + $25). PSI's bulletin charges $69 "for each registration" but doesn't say whether booking both exams together counts as one registration or two. Check the total when you book. Local registration is extra where it applies: Canton, for example, charges $150 a year (see City rules).

Deadlines and waiting periods

Insurance and company rules

The license is issued in your name, and you assign it to the contracting company you work for (ORC 4740.07). The rules that follow from that:

• One company at a time. You can't assign the same license to a second company, and no DBAs are allowed. While a company holds your license, you can't get another license of the same type.
• Insurance in the company's name. You need at least $500,000 of contractor liability, including completed-operations coverage. The company must be registered with the Ohio Secretary of State (OAC 4101:16-2-09(D)). This is liability insurance, not a surety bond.
• You answer for the work. The company's work under your license counts as done under your personal supervision. You must be actively engaged in the business and available for consultation.
• License number on ads. It must appear on advertising that shows the company name, including vehicles, business cards, websites and directory ads (OCILB).
• No pulling permits for others. If you pull a permit, you must be the contractor in charge.
• Not assigned means inactive. If your license isn't assigned to a company, it goes into inactive status.

Do you also need a city registration?

Often, yes. Ohio doesn't stop cities from regulating electrical installations or registering tradespeople. A city that requires contractor registration with a fee must also require the state license (ORC 4740.12).

Canton is one example. Its electrical contractor registration requires:

• a valid state license;
• a $75 application fee and a $150 annual registration;
• a $10,000 surety bond;
• proof of workers' compensation coverage;
• city income tax registration.

Canton renewals are due by December 31 (Canton Codified Ordinances §1313.04). Other cities set their own terms. State law also allows local registration of individual tradespeople.

Before your first job in a new place, call that building department. Ask what registration, bond, insurance and permit steps it requires for electrical contractors.

Renewal and continuing education

Licenses expire every year on the date of your original license (ORC 4740.06(H)). Renew online through OCILB eLicense.

How many continuing education (CE) hours you need depends on whether you're in OCILB's Compliant Contractor Program. Existing licensees join after a year of on-time renewals with no discipline. New licensees must complete a compliant licensure period first (OAC 4101:16-1-08).

Sources: OAC 4101:16-2-08(A); OAC 4101:16-1-08(C).

A few more rules:

• Courses must come from OCILB-approved training agencies. Search them with the OCILB CE lookup.
• Extra hours don't carry over to the next renewal.
• You can earn no more than 10 hours of credit in one day.
• Program members who don't want to do three years at once can still renew annually.
• You no longer send proof of insurance with a renewal, but you must keep the coverage in force.

Taking a break? You can request inactive status. While the license is inactive, you are exempt from the continuing-education requirement and do not have to maintain contractor liability insurance. To return an inactive license to active status, the current rule requires the applicable accumulated CE (capped at 30 hours, or 24 hours if you were in the Compliant Contractor Program when the license became inactive), a $60 reactivation fee and proof of the required insurance (OAC 4101:16-2-12).

Criminal record? Check before you apply

Ohio's current OCILB notice says a licensing authority cannot refuse to issue a credential solely because a person was charged with or convicted of an offense, or because of a vague standard such as "moral turpitude" or "moral character." But specific convictions with a direct nexus to the occupation can still affect an initial license application under Ohio law (OCILB disqualifying-offenses notice; ORC 4740.06(L)).

OCILB says listed offenses are not automatically disqualifying; the facts are reviewed individually. Factors can include:

• how serious the offense was;
• how much time has passed and whether court-ordered terms were completed;
• whether other offenses occurred;
• how the offense relates to the duties of the occupation;
• evidence of rehabilitation or treatment; and
• whether denial is reasonably necessary for public safety.

If you have a conviction, judicial finding of guilt or guilty plea, you can file a Pre-Determination Request before applying to ask whether it may disqualify you. See the OCILB disqualifying-offenses notice, which links the form.

Renewal is different: ORC 4740.06(L) limits the Board's use of past criminal activity in renewal decisions and says a conviction or guilty plea from before the initial license may not be considered when the license is renewed.

Five things people get wrong about this license

1. "Ohio has an OCILB state journeyman license." It doesn't. OCILB licenses contractors; worker or journeyman credential requirements, where imposed, come from local authorities.
2. "Everyone renews every two or three years." Renewal is annual. The three-year option is only for Compliant Contractor Program members.
3. "You need 40 CE hours to renew." Forty code hours is one way to document experience when you apply. Renewal takes 10 hours, or 8 (24 over three years) in the program.
4. "You retake Business & Law for every new trade." A passed Business & Law exam counts for three years from license issuance if you apply for another trade.
5. "The license belongs to the company." It's issued to you and assigned to one company. When you leave, a 90-day clock starts unless the company signs a release.

Common questions

Can I take the exams before I have insurance? Yes. Insurance comes at issuance, when you send the certificate for the company you're assigning the license to. You can also ask for inactive status instead.

Does residential experience count toward the five years? It can under Route 3, where at least three of the five years must be construction work on commercial or residential projects in the trade. If your records don't clearly fit Route 1, describe your duties specifically on the form and choose the supporting proof that shows most of your five years in the trade.

How do I check whether a contractor is licensed? Use OCILB's licensee lookup or the current licensee roster.

Where official sources differ, we followed the controlling statute or rule. The continuing-education rules set 10 hours for an ordinary electrical-only renewal and give the two-hour reduction to Compliant Contractor Program members. PSI's bulletin says candidates can retest up to five times in a year, while current ORC 4740.06(G) says a new application is required after five failed attempts; the statute controls that licensing rule.
