Reciprocal agreements
Kentucky has limited reciprocal agreements, primarily with Ohio for HVAC and electrical licensing, and with Virginia and West Virginia for electrical licensing. For other trades, Kentucky may recognize out-of-state credentials on a case-by-case basis if the issuing state’s standards are substantially equal.Reciprocity in Kentucky is trade-specific, not statewide. Always confirm which DHBC division handles the trade before assuming an out-of-state credential transfers.
| Trade | Reciprocal states | Coverage |
|---|---|---|
| HVAC | Ohio | 1 state |
| Electrical | Ohio, Virginia, West Virginia | 3 states |
| Manufactured home installation | HUD license holders and states with reciprocal agreements | Limited |
| All other trades | Case-by-case if issuing state has substantially equal standards | Case-by-case |
Kentucky's case-by-case recognition process
Kentucky's case-by-case recognition process
Kentucky may recognize, on a case-by-case basis, out-of-state credentials for an applicant that holds a current license, certification, or registration in another state whose standards are substantially equal to those required by the Commonwealth. This is not automatic — applicants must apply through the relevant DHBC division and demonstrate equivalency.
