Ohio Contractor License Lookup

Ohio does not license general contractors or residential builders at the state level — but commercial work in five trades (electrical, HVAC, hydronics, plumbing, and refrigeration) requires an OCILB license. Verify it in the official eLicense Ohio look-up, the same system Ohio's licensing boards point to as the primary source.

Good to know: There is no Ohio state general contractor license. OCILB licenses the five commercial trades above; residential and general contracting are handled by local registration in many cities. If a GC can't be found in eLicense, check the trade licenses of the crew and the city's contractor registration list.

The official lookup: Ohio Construction Industry Licensing Board (OCILB) — via eLicense Ohio

Search by last and first name, or full license number, with the licensing board selected. This is the board's live database — the same record building departments and insurers check.

How to verify a Ohio contractor in 3 steps

  1. 1

    Get the license number

    Ask the contractor for it — in most states it must appear on their contracts, bids, and advertising. No number? The search also works by business or owner name.

  2. 2

    Search the OCILB database

    Open the official search above and look up the record by last and first name, or full license number, with the licensing board selected.

  3. 3

    Read the record like an inspector

    Status must be active, the name must match your contract, the classification must cover your project, and the expiration date must be in the future. Check disciplinary actions before you sign.

Ohio license lookup FAQs

Does Ohio license general contractors?

Not at the state level. Ohio licenses commercial contractors in five trades through OCILB — electrical, HVAC, hydronics, plumbing, and refrigeration. General and residential contractors are typically registered locally with the city or county building department instead.

How do I search eLicense Ohio for an OCILB contractor?

Open the eLicense look-up linked above, choose "License Look Up," enter the last and first name (or the full license number including any prefix), and select the Ohio Construction Industry Licensing Board from the board list. The record shows the license type, status, and expiration date.

What if the contractor isn't in the board's database?

Either the license isn't active, the details were entered differently (try the owner's name, not just the business name), or the contractor isn't licensed. Ask the contractor for their license number and search by number — if it still doesn't appear, do not hire them for work that requires a license.

How often should I re-check a license?

Verify before you sign, and again before final payment on long projects. Licenses can be suspended mid-project, and a lapsed license can void insurance coverage and leave you outside the board's complaint process.

A license lets a contractor work — a permit lets the project start. Browse Ohio permit portals for the official building department links, or look up a contractor in another state.
