Do I need a permit for water heater replacement in Kansas City?
It depends. Whether water heater replacement needs a permit in Kansas City comes down to the details of your project.
Kansas has no statewide residential building code; whether a permit is required depends on whether the city or county has adopted a code by ordinance or resolution (K.S.A. 12-3009, 12-3302, 12-3303). Cities and counties, not the state, set licensing for plumbing and other trades (Kansas Business Starter Kit). The first question is which city or county, if any, enforces a building code at the address.
Local detail for Kansas City: Kansas City, Kansas is governed by the Unified Government of Wyandotte County and Kansas City, which issues building permits for the city.
