Verdict

Licensure by endorsement

Read Ohio's agreements one trade at a time — that is the mistake most contractors make here. A deal that waives the electrical exam says nothing about general building, and a commercial agreement rarely covers residential work. The tables below separate them so you can see exactly which of your licenses travels and which does not.

OCILB issues STATE licenses only to COMMERCIAL Electrical, HVAC, Plumbing, Hydronics, and Refrigeration contractors (exam-based); general/residential construction is not state-licensed in Ohio (regulated locally). Reciprocity is limited and trade-specific, offered only to applicants who passed the state-recognized exam (grandfathered licensees excluded): Alabama (HVAC, Refrigeration); Arkansas (Plumbing); Kentucky (Electrical, HVAC, Refrigeration); Louisiana (Electrical, HVAC, Refrigeration +B&L); Mississippi (Electrical, HVAC, Refrigeration, Plumbing +B&L); North Carolina (Electrical); South Carolina (Electrical, HVAC, Plumbing +B&L); Tennessee (Electrical, HVAC, Refrigeration, Plumbing, Hydronics +B&L); West Virginia (Electrical, HVAC, Plumbing). Fee is $25 per trade. Refrigeration and hydronics are captured in the notes above rather than as separate trade keys. Live com.ohio.gov blocks automated access; reciprocity/trade/fee content verified via Internet Archive snapshots (Apr-Jun 2025) of the official OCILB pages, and the eLicense verification portal was verified live.
