When does a master or journeyman plumbing license typically expire?

A master or journeyman plumbing license typically expires on the last day of the license holder's birth month. This practice is in place to standardize the renewal process, making it easier for individuals to remember their renewal dates. By aligning the expiration date with the license holder's birthday, it encourages timely renewal and helps ensure that plumbers maintain current certifications and are up to date with industry standards.

The other options, such as an expiration at the end of the calendar year, every two years on March 31, or the end of the fiscal year, do not align with the typical regulatory structure in Kentucky for plumbing licenses, which focuses on the individual’s birth month for expiration and subsequent renewal.
