Master Plumber
What this license lets you do: “You take responsible charge of journeyman plumbers, apprentices and others installing or changing plumbing, and you may design, plan, supervise and contract for plumbing work. Plumbing permits are issued to master plumbers.”
How to apply: “Applications must be completed correctly and in the Frankfort office no later than three weeks prior to the exam date.”
About the exam: “A maximum of 2 1/2 hours is allowed for completion of the exam. You need at least 80% on each part: written questions on plumbing, KRS 318 and the regulations, and sizing the pipes on a drawing of stacks, wastes and vents.”
The Master Plumber license costs $250.
You must pass the Kentucky master plumber examination. The exam costs $150.
You renew the Master Plumber license every year. The renewal costs $250. You need 6 hours of continuing education for each renewal.
The $250 covers a 1-year license. Your first license runs to your birth month, 7 to 18 months away, so the first fee is $146 to $376.
If your first renewal is less than 12 months after you got your license, you can renew without the 6 hours.
