Plumbing permits are issued to Master Plumbers or Drainlayers who are licensed by St. Louis County. Plumbers licensed by St. Louis County also receive a license from University City. One may verify that a contractor is licensed by calling the Community Development Department or visiting the following website. Plumbers must show proof of license from St. Louis County as well as a second form of identification (such as a driver's license) when applying for a permit with University City.

An owner can receive a plumbing permit if the following conditions are met:

  1. The owner occupies the home.
  2. The owner personally performs all the work.
  3. The owner obtains a plumbing permit to perform work that meets the standards of University City's adopted ordinances and codes.
  4. The owner passes an open book exam. The exam is based on the currently adopted edition of the International Residential Code (Chapters 33-40). A current edition of the code book is available for use at the Community Development Department.
The owner's permit is applicable only to single-family, owner occupied units.
