Ohio Contractor License Lookup (OCILB): HVAC, Electrical & Plumbing Contractors

Look up, verify and export Ohio commercial contractor licenses straight from the Ohio Construction Industry Licensing Board (OCILB)'s own eLicense roster, current to the day: about 12,400 active licenses in the 5 trades Ohio licenses at state level: electrical (EL), HVAC (HV), plumbing (PL), hydronics (HY) and refrigeration (RE). Each record has the qualifying individual's name, company, address, county, phone (about two thirds of records), email (a few percent), effective and expiration dates and an "in renewal" flag.

• Verify contractors by license number (HV.10704) or by company or qualifier name, in bulk.
• Export lead lists: every licensed HVAC contractor in Franklin County, every electrical contractor in Cleveland, every plumber in a ZIP range, with the qualifier's name and phone.
• Renewal, continuing-education, insurance and bonding leads: licenses expiring in the next N days.

No login, no browser, no CAPTCHA: the actor generates OCILB's public roster (the same Generate Roster → CSV download anyone can use on the Ohio eLicense Center) at run time, so a statewide run takes a few seconds and costs a fraction of a cent in compute.

Data and limits

• Source: Ohio eLicense Center, OCILB roster download (Ohio public record, free). Pulled live on every run; dataAsOf is the run date. A run stops with an error rather than returning a partial roster if OCILB's download comes back truncated.
• Ohio licenses only these 5 commercial trades at state level. Residential contractors, roofers, general contractors and home-improvement contractors are registered by cities and counties, not OCILB, so they aren't in this data.
• The roster lists active licenses only (including licenses in renewal) and has no original issue date, so there's no "newly licensed since" filter. Check verifyUrl (Ohio's own lookup) for expired licenses and disciplinary history.
• Names and addresses are exactly as OCILB publishes them. This is public licensing data; use it in line with Ohio and US law (including telemarketing and anti-spam rules).
• Not affiliated with or endorsed by OCILB or the State of Ohio.
