How to Become a Licensed Plumber in Missouri
Missouri Plumbing License Requirements
Although there’s no state license for Missouri plumbers, counties and cities have unique licensing requirements.
County and city governments provide oversight, and those seeking a journeyman or master plumber’s license must pass an exam to work in cities with populations over 15,000.
St. Louis and Kansas City are the state’s most densely populated cities, and each has stringent plumbing license requirements.
Each city requires apprentices to work under a journeyman or master plumber’s supervision to gain the experience needed to pass the exam and apply for a qualification certificate. Before working in an area, check with its government to learn its licensing requirements.
Missouri Plumbing License Exams
According to Missouri law, each city with a population over 15,000 shall require plumbers to pass an exam before earning their licenses.
Examination scheduling is explained on city websites. When an application is accepted, the prospective plumber will receive a registration form in the mail.
With the form, they also get information on exam content, fees, references, format, locations, dates, deadlines, and much more.
In the city of St. Louis, applicants can sign up and pay the exam fee online.
Who Issues Missouri’s Plumbing Licenses?
Master plumbers and journeymen must be certified to provide services within the state, but they earn those certifications in their respective counties and cities.
The method by which a plumber obtains their license varies by jurisdiction, so applicants should contact the local government in the area where they plan to work.
Additional Plumbing Certifications in Missouri
While the state doesn’t require them, certifications can demonstrate a plumber’s proficiency and marketability.
Certificates from the International Association of Plumbing and Mechanical Officials and National Inspection Testing and Certification make plumbers more compelling prospects for customers and potential employers.
Can I Transfer a Plumbing License to Missouri?
There is no plumbing license reciprocity in Missouri, meaning licenses from out of state cannot be transferred into Missouri.
