Transfer Your Plumber License to Kentucky: Reciprocity & Endorsement (2026)
Does my plumbing license transfer to Kentucky?
No — Kentucky has no plumbing reciprocity with any state. To be licensed you qualify as a new applicant through the Kentucky Department of Housing, Buildings and Construction — Division of Plumbing: Kentucky has no plumbing reciprocity; every applicant, including out-of-state plumbers, must pass the Kentucky journeyman plumber examination (written, drawing, and practical sections, minimum 75% each). An out-of-state plumbing license may be submitted only as proof of the required experience, not as a substitute for the exam. Your out-of-state hours usually count toward the experience requirement; your license does not skip the exam. Application fee: $110 ($50 journeyman examination fee + $60 initial license fee (total $110 to become licensed); journeyman renewal is $60. Fees set by 815 KAR 20:030. Master plumber tier: $150 exam + $250 license.).

Verdict
Full re-application required
The honest news first: there is no shortcut into Kentucky for an out-of-state plumber, because Kentucky recognizes no other state's plumbing license. The productive framing is that your logged apprenticeship and on-the-job hours usually count toward Kentucky's experience requirement, so the real work is documentation and the journeyman exam, not starting your career over. Pull the Kentucky Department of Housing, Buildings and Construction — Division of Plumbing's current experience rules early, order your certified license history and employment records — the long-lead item — and treat the exam as a review of work you already do. The steps below are the new-applicant path, annotated for someone who has done the job before.
Kentucky has no journeyman plumber reciprocity: all applicants must pass the Kentucky journeyman exam, so endorsement_available is false — an out-of-state license only serves as proof of the required two years of apprentice experience (i.e., it saves the applicant from redoing a Kentucky apprenticeship but not from the exam). Fees ($50 exam, $60 license, $60 renewal) are set by 815 KAR 20:030; master plumber is a separate higher tier ($150 exam / $250 license). Verification is via the DHBC public license search; no national plumber database exists.
