Plumbers in Kansas

How Kansas licenses plumbers

There is no statewide plumber license; cities or counties license plumbers.

Who licenses: Local governments

Businesses: Kansas's official business portal says cities and counties set licensing requirements for construction and contracting businesses, including plumbing trade licenses, so contractor licensing for plumbing comes from the local city or county.

Local rules: Plumbing licenses are set and issued by individual cities and counties, so requirements vary by jurisdiction.

Call your city or county building or permitting department to find out which plumbing license it requires, and ask the plumber for that local license number before hiring.

We could not confirm every detail from Kansas’s own sources, so treat this as a starting point and check with the agency.

Before you hire

Ask for the license number and check it on the official lookup where one exists. Ask for proof of insurance and a written, itemized estimate, and ask who pulls the permit if the job needs one – water heaters, repiping and sewer lines often do.
