Replacing a water heater in Kirkwood.
Kirkwood issues its own plumbing permits, including for water heaters, on the Kirkwood Public Portal. The plumber needs both a St. Louis County license and a Kirkwood Contractor's Business License. Most homes get electricity from the city-owned Kirkwood Electric and water from the city, which buys it from Missouri American Water. Spire supplies gas. The city switched to the 2021 International Plumbing Code on April 1, 2026.

- Yes · City of Kirkwood Building Division
- Who gets the permit
- The permit application says a permit isn't valid until it's signed by plumbing (and electrical or mechanical) contractors with an active Kirkwood Contractor's Business License. Plumbing contractors also need a St. Louis County license. We found no homeowner permit option on the city's pages.
