Does Kansas Require a Plumbing License? Who Licenses Plumbers Instead

No. Kansas licenses plumbing locally: the state issues no plumber license.

Under K.S.A.

12-1508 to 12-1511, any county or city that requires the licensure of plumbers practicing within its borders may conduct the examinations and issue the credentials, following the uniform standards the statute sets.

Whether you need a certificate — and which level — is decided by the county or city where the work happens.

There is no state application, state exam or state fee to plan around; plan around the city or county instead.

Kansas's plumbing credentials are local: the journeyman plumber certificate, the master plumber certificate and the plumbing contractor licence, issued by the county or city that requires licensure.

The statute describes the local program as determining the qualification of persons seeking licensure as plumbing contractors and master and journeyman plumbers.

What each credential allows on the job is set by the local ordinance, and our research did not capture individual cities' scope rules — ask the issuing jurisdiction what a journeyman may do unsupervised and what a master or contractor may sign off.

One rule the state standards add everywhere: medical gas piping may be installed only by a plumber licensed under them who also holds the appropriate ASSE Series 6000 certification.

Journeyman plumber: before issuing the certificate, the jurisdiction must verify documented proof of a minimum of 2 years of field experience.

Kansas defines field experience as working under the direct supervision of a person holding a valid journeyman or master certificate, or attending trade-related schooling, and up to 1 year of it can be trade school of at least 930 program hours.

Kansas sets no statewide apprentice registration with a licensing board — experience is documented as supervised work or trade schooling.

Master plumber: 2 years holding a valid journeyman certificate or 4 years of field experience.

Fees: our research did not capture local application, examination or certificate fees, and there is no state fee to quote — ask the city or county where you will apply.

There is no state plumbing exam: the county or city that licenses plumbers conducts the examinations.

Kansas law designates which tests count as the standard plumbing competency exams — those promulgated or administered by the International Code Council (ICC), the International Association of Plumbing and Mechanical Officials (IAPMO) or Prometric — and localities set a minimum passing score of 75%.

Our research does not describe what the exams cover or which exams a given jurisdiction uses; the issuing jurisdiction and the exam publisher are the places to confirm before you book.

The continuing-education floor is set in state statute: local plumbing licensees must complete not less than 12 hours of continuing education every two years, or 6 hours annually, and at least half of it must be code education.

The rest of the renewal picture is local — our research did not capture the renewal cycle, renewal fees or how individual jurisdictions approve courses.

Confirm the cycle and the current hours with the office that issued your certificate before you count anything.

Kansas's portability rule runs inside the state, not across state lines: a plumbing licence based on the designated standard exams is valid in any other Kansas county or city that requires examination and licensure of plumbers.

Out-of-state acceptance has no statewide rule to point to — there is no state plumbing licence to reciprocate with, and our research found no statewide recognition provision — so each jurisdiction decides.

If you hold a journeyman or master certificate from another state, ask the building or licensing department where you want to work what it accepts before you assume you must retest.

There is no statewide lookup, because there is no statewide licence: each county or city that licenses plumbers keeps its own records and sets its own way to check them.

To verify a plumber's credential — yours or a contractor's — contact the building or licensing department of the jurisdiction that permits the work.

Be cautious with any service offering to look up a 'Kansas state plumbing license': the state issues none, so any such record would be local.

Any county or city that requires plumber licensure may conduct examinations under the uniform standards in K.S.A.

12-1508 to 12-1511; there is no statewide requirement, so whether you need a licence is decided locally.

Our research confirmed the framework but not the offices: examples of Kansas local licensing bodies, such as the Wichita–Sedgwick County Metropolitan Area Building and Construction Department and Johnson County's contractor licensing program, appeared in the research but were not verified, so we do not present them as confirmed plumbing licensing offices.

Contact the building or licensing department where the work will be done — it decides whether you need a certificate, which level, and what it takes.

Medical gas piping has its own rule in the statute: it may be installed only by a plumber licensed under the state standards who also holds the appropriate ASSE Series 6000 certification.

Our research did not cover backflow tester certification or separate gas-fitting credentials for Kansas plumbers — if a job involves backflow devices or gas piping beyond medical gas, ask the local building or plumbing department what it requires where you work.
