Ohio Low Voltage Contractor License Requirements (2026)

Ohio splits low-voltage licensing across three agencies. The Ohio Construction Industry Licensing Board (OCILB) within the Department of Commerce issues the statewide Fire Protection Contractor license under R.C. 4740.06, which is required for fire alarm and fire suppression installation on commercial projects. Structured cabling and general low-voltage work is not separately licensed at the state level, but the State Fire Marshal additionally certifies fire alarm installers and inspectors under R.C. 3737 and O.A.C. 1301:7-7. Burglar alarm, CCTV, and access-control companies must register as a Class B Security Services Provider with the Ohio Department of Public Safety Private Investigator Security Guard Services (PISGS) section under R.C. 4749. Cincinnati, Cleveland, Columbus, Dayton, and Toledo also require a local electrical contractor registration for any low-voltage work tied to building systems.

Governing Authority

Under Ohio Revised Code Chapter 4740; Ohio Administrative Code 4101:15 (OCILB rules), Ohio Construction Industry Licensing Board (OCILB) is the body that issues this license and enforces compliance with it. The Ohio Construction Industry Licensing Board, housed inside the Ohio Department of Commerce Division of Industrial Compliance, issues statewide commercial licenses for Electrical, Plumbing, HVAC, Hydronics, and Refrigeration contractors. Ohio has no statewide general contractor license — general building work is regulated at the municipal level.

Phone: (614) 644-3493

Eligibility Requirements

To qualify, an applicant must have reached age 18 and hold a valid Social Security Number. No Ohio residency requirement. OCILB Fire Protection applicants must maintain an Ohio business address.

Good moral character

OCILB and PISGS both conduct fitness reviews. Felony convictions within the last ten years are reviewed individually and may result in denial under R.C. 4776.

Background investigation

Mandatory fingerprint-based BCI and FBI background check for the OCILB qualifying individual and every PISGS Class B registrant.

Experience & Education Matrix

Eligibility requires five years of practical experience in fire protection, fire alarm, or electrical systems installation under a licensed contractor, or a bachelor degree in engineering with three years of practical experience (R.C. 4740.06(B)), documented and independently verifiable. Payroll, tax, project, and supervisor records are the usual proof the board will accept.

Accepted proof of experience or eligibility

OCILB Experience Affidavit signed by each supervising licensed contractor
W-2 statements, pay stubs, or 1099 records covering the five-year qualifying period
NICET Fire Alarm Systems Level II or III certificate
Engineering degree transcripts (if claiming the education substitution)

Education substitution

A bachelor degree in mechanical, electrical, or fire protection engineering from an ABET-accredited program reduces the experience requirement to three years under R.C. 4740.06(B)(2).

Examination Structure

Examinations are administered by PSI Services LLC under contract to OCILB. The applicant must pass the following examination parts before the license can issue:

OCILB Fire Protection Trade examination — NFPA 72, NFPA 70 Article 760, Ohio Fire Code — 100 questions, 240 minutes, passing score 75%
OCILB Business and Law examination — 50 questions, 120 minutes, passing score 75%

Examination fee: $75 per section paid to PSI on registration ($150 total for both sections).

Retake policy: Failed sections may be re-taken after a 30-day waiting period by paying a new exam fee. Each OCILB application remains valid for twelve months.

Insurance & Financial Security

A contractor license surety bond of $25,000, on the OCILB's prescribed form, is a precondition to issuance.

General liability

OCILB requires the Fire Protection Contractor to carry a minimum $500,000 commercial general liability policy under O.A.C. 4101:18-1-05. Most commercial owners contractually require $1,000,000/$2,000,000.

Workers' compensation

Workers' compensation coverage through the Ohio Bureau of Workers' Compensation is mandatory for any Ohio employer under R.C. 4123.

Additional financial requirements

No financial statement required for the OCILB Fire Protection classification. PISGS Class B registration requires proof of $100,000 liability.

Application and License Fees

Fee	Amount
Application (non-refundable)	$360

Reciprocity and Endorsement

Ohio does not accept the NASCLA Accredited Examination for this classification.

Reciprocal State	Accepted Exam	Conditions
Kentucky	Fire Protection trade exam waived	Bilateral OCILB reciprocity for active Kentucky HBC electrical/fire alarm contractors with three years active status.
West Virginia	Fire Protection trade exam waived	Bilateral OCILB–WV reciprocity for active fire protection contractors.

OCILB maintains limited bilateral reciprocity with neighboring states for the Fire Protection classification. Reciprocal applicants must still pass the Ohio Business and Law examination and meet insurance requirements. NICET Fire Alarm Systems Level II is recognized as study credit but does not waive licensure.

Step-by-Step Application Roadmap

Confirm scope. Fire alarm commercial = OCILB Fire Protection + State Fire Marshal certification. Burglar alarm / CCTV / access control = PISGS Class B Security Services Provider. Structured cabling = no state license but most major cities require local registration.
Document five years of qualifying experience. Compile OCILB Experience Affidavits covering five years of fire protection, fire alarm, or electrical installation under a licensed contractor. Engineering degree holders may reduce to three years.
Earn NICET Fire Alarm Systems Level II. NICET Level II is the industry prerequisite and strengthens the OCILB application. Level III is required for plan review.
Submit the OCILB Fire Protection Contractor application. File the application with the $360 fee, experience affidavits, BCI/FBI fingerprints, and $500,000 liability certificate.
Pass the PSI Fire Protection trade and Business and Law examinations at 75%. Score 75% or better on both the 100-question trade exam and the 50-question Business and Law exam.
Register with the State Fire Marshal for fire alarm acceptance testing. File the State Fire Marshal Fire Alarm Inspector/Installer certification with NICET Level II evidence and the $150 fee.
File the PISGS Class B registration for burglar alarm work. File the Class B Security Services Provider application with the $375 fee, $100,000 liability certificate, and fingerprint-based background check.
Renew OCILB annually on the anniversary cycle. OCILB Fire Protection renews every year on the licensee anniversary date and requires eight hours of continuing education.

Common Filing Mistakes

Drawn from the board instructions and sources cited on this page, the pitfalls below are the ones most likely to slow down or sink a Ohio Low Voltage application.

Assuming OCILB covers burglar alarm

The OCILB Fire Protection classification covers fire alarm only. Burglar alarm, CCTV, and access-control work requires a separate PISGS Class B registration with the Department of Public Safety.

Skipping the State Fire Marshal certification

The OCILB Fire Protection license authorizes the business, but the individual performing fire alarm acceptance testing must additionally hold State Fire Marshal certification with NICET Level II evidence.

Ignoring city registration

Cincinnati, Cleveland, Columbus, Dayton, and Toledo require separate local electrical contractor registration for any low-voltage work tied to building systems. The OCILB license does not pre-empt local registration.

Insufficient liability insurance

OCILB requires $500,000 minimum commercial general liability. Many out-of-state applicants arrive with only $300,000 and must increase coverage before the license issues.

Letting the OCILB license lapse

OCILB Fire Protection renews annually. A lapsed license carries a 25% late penalty and, if lapsed more than one year, requires retesting the trade and Business and Law sections.

Frequently Asked Questions

Does Ohio have a statewide low-voltage electrician license for cabling?

No. Pure structured cabling and telecom work has no OCILB credential. Fire alarm requires the OCILB Fire Protection Contractor license plus State Fire Marshal certification, and burglar alarm / CCTV requires PISGS Class B registration. Cincinnati, Cleveland, Columbus, and most major Ohio cities require separate local electrical contractor registration.

How much experience does OCILB require for the Fire Protection Contractor license?

Five years of practical experience in fire protection, fire alarm, or electrical systems installation under a licensed contractor. A bachelor degree in engineering from an ABET-accredited program reduces the requirement to three years.

What is a PISGS Class B registration and who needs one?

A Class B Security Services Provider registration is issued by the Ohio Department of Public Safety Private Investigator Security Guard Services section for any business installing burglar alarm, CCTV, or access-control systems. It requires a $375 fee, $100,000 liability, and fingerprint-based BCI/FBI background clearance.

Does Ohio accept NICET certification toward licensure?

NICET Fire Alarm Systems Level II is required by the State Fire Marshal for fire alarm acceptance testing and is widely recognized as study credit for the OCILB Fire Protection trade exam, but it does not waive OCILB licensure.

How often does the OCILB Fire Protection Contractor license renew?

Annually on the licensee anniversary date. Renewal requires eight hours of continuing education including a code-update course and proof of continuing $500,000 liability coverage.
