Replacing a water heater in Florissant.
In Florissant, a water heater is a $95 'quick issue' permit from the city's own Public Works Department, with no plan review. The city's plumbing code requires a plumber licensed by St. Louis County, but owners of a detached house can get a homeowner permit after showing they know the code. Florissant homes are on Ameren Missouri electric, Spire gas and Missouri American Water.
