Choosing an access control installer in Ohio

Commercial contractors in 5 trades get their license from the Ohio Construction Industry Licensing Board, also called OCILB. The trades are electrical, HVAC, plumbing, hydronics and refrigeration. That list leaves out low voltage work: the thin wiring used with readers, keypads and door strikes.

Section 4740.13 of the Revised Code adds more detail. Someone who works on specific systems under 50 volts is not treated as an electrical contractor. It includes cabling, tele-data, sound, communication and fire or burglar alarm systems.

You won't find access control named in that list. A reader connected to a burglar alarm might fit the list; a door system on its own is harder to pin down. Ohio's official pages leave that question unanswered.

Anything above the 50-volt line changes the rules. For commercial electrical work you need an OCILB license. Local departments with a registration process must see the state license before handing out commercial permits.

The board asks for 5 years in the trade as a tradesperson, or alternative experience it accepts, before you can take the exam. The board also sets an amount for contractor's liability insurance that the applicant has to hold.

When doors connect to a fire alarm, the State Fire Marshal gets involved. Any company that installs or services smoke and fire detection for pay must hold a Fire Protection Certification. A bond of at least $50,000, or proof of liability insurance, must be sent in.

A company pays $200, while a sole proprietor pays $50. A certified company can work only in the categories its own certified staff cover.

Cities often step in where the state leaves off. Columbus requires every contractor on jobs in the city to have the right license or registration before any permit application. Check with your city, county or township building department about what it demands for low voltage door work.

• To check an electrical license, go to the state's contractor verification page; it connects you to a company lookup and a separate individual lookup.
• Your project may or may not need a permit; check with the local department. A contractor who won't get permits is a red flag, according to state guidance.
• Insurance: ask for proof and the insurer's contact info, then call the insurer.

The Board of Building Standards took the 2021 International Codes, added Ohio amendments, and issued the 2024 Ohio Building Code. The effective date was March 1, 2024. Its rule text references NFPA 70-23, the 2023 National Electrical Code, as a standard.

A section Ohio wrote, 1010.2.16, deals with temporary door locking devices that block intruders from a room. These devices need the building official's sign‑off and a mark on the certificate of occupancy. Staff at schools may only engage them during an emergency or an active shooter drill.

Keys and access cards, along with other non‑fixed hardware, get an exception under section 1010.2.2 through a separate Ohio amendment.

According to the state's verification page, Ohio does not require residential contractors to hold a license. They're overseen by local building departments, and some of those may still want the state commercial license.
