Ohio Intercom Permit Requirements: No State License Needed

Ohio does NOT require a state contractor license for most low voltage work, including intercom installation. Work under 50 volts is specifically exempt from OCILB electrical licensing. However, if your intercom integrates with security systems, separate licensing may apply.

Quick Answer

Ohio exempts low voltage work under 50 volts from state electrical licensing per Ohio Revised Code Section 4740.13(D). Standalone intercom systems fall under this exemption. No OCILB license is required. However, some municipalities have local licensing requirements, and security-integrated systems may require licensing under Ohio House Bill 41 Section 4770.

Ohio Revised Code Exemption

Per Ohio Revised Code Section 4740.13(D), low voltage work is specifically exempt from electrical contractor licensing:

"A person is not an electrical contractor subject to licensure under this chapter for work that is limited to the construction, improvement, renovation, repair, testing, or maintenance of the following systems using less than fifty volts of electricity: fire alarm or burglar alarm, cabling, tele-data sound, communication, and landscape lighting and irrigation."

Intercom systems fall under "communication" in this exemption.

What This Means for Contractors

No State License Required For:

Standalone intercom systems
Video doorbell installation
Apartment/building intercom systems
Paging and PA systems
Data and network cabling
Telephone systems
Sound systems

When Licensing MAY Apply:

Scenario	License Required?	Authority
Standalone intercom	No	ORC 4740.13(D) exemption
Intercom with access control	Possibly	May fall under security systems
Security-integrated intercom	Yes	HB 41 Section 4770
Commercial electrical work over 50V	Yes	OCILB electrical license

Security System Licensing (HB 41)

Ohio House Bill 41 Section 4770 requires separate licensing for individuals who sell, install, monitor, maintain, repair, test, or inspect security or life-safety systems for profit.

If your intercom installation includes:

Burglar alarm integration
Access control systems
Monitored entry points
Life-safety functions

You may need to be licensed under the security systems regulations, separate from electrical licensing.

OCILB Electrical Licensing

The Ohio Construction Industry Licensing Board (OCILB) regulates electrical contractors for commercial work. Key points:

Only commercial electrical contractors need OCILB licenses
Residential electrical work doesn't require state licensing (local may apply)
Low voltage under 50V is explicitly exempt

Local Requirements

While Ohio has no state low voltage license, many municipalities have local requirements:

Columbus

Check with the Columbus Building & Zoning Services Division for contractor registration and permit requirements.

Cleveland

Cleveland may require contractor registration for certain work. Contact the Building & Housing Department.

Cincinnati

The Cincinnati Department of Buildings & Inspections handles local permits. Low voltage work may be exempt but verify locally.

Other Cities

Always check with the local building department. Ohio's home rule allows cities to establish their own requirements.

Low voltage systems under 50V
Residential installations
