Do I need a permit for plumbing fixture or repiping in Unincorporated Caldwell County?
Most likely yes. Plumbing fixture or repiping usually requires a permit in Missouri. Confirm the specifics with Unincorporated Caldwell County.
RSMo 341.060 directs each city of 15,000 or more residents to require a permit for plumbing work and to create a plumbing inspector office under RSMo 341.070. Missouri has no statewide plumbing license; RSMo 341.010 requires master and journeyman plumber certificates in cities of 15,000 or more, issued through local boards. Outside those cities, plumbing rules and permits depend on the local code, and many rural areas have none. Missouri has no statewide residential building code; whether a permit is required depends entirely on the city or county code that covers the address. Work that moves or replaces pipes, rather than swapping a fixture, alters the plumbing system itself and is not covered by fixture replacement exemptions. Pipe work normally requires a plumbing permit, a pressure or air test, and a rough in inspection before walls are closed, and many jurisdictions require a licensed plumber to pull the permit.
Local detail for Unincorporated Caldwell County: Caldwell County issues a permit under its county zoning rules, but has not adopted a residential building code for unincorporated areas, so the work may not be inspected to a building code. Ask the office what the permit covers and whether any inspections apply.
