Missouri Plumbing License: Everything You Need to Know

In Missouri, plumbing licenses are regulated locally rather than at the state level. Requirements and processes vary by city or county, with major cities like St. Louis and Kansas City setting their own licensing, insurance, and renewal criteria. This guide provides an overview of key steps, average salaries, and important considerations for obtaining and maintaining a plumbing license in Missouri.

What plumbing work can be done without a license?

Missouri does not enforce a statewide plumbing license, so local regulations determine what work requires a license. Typically, counties and cities require licenses for most plumbing work to ensure public safety and code compliance. Check with your local licensing board for specifics.
