Do I need a permit for swimming pool or spa in Chesterfield?
Most likely yes. Swimming pool or spa usually requires a permit in Missouri. Confirm the specifics with Chesterfield.
Missouri has no statewide barrier law for private residential pools; barrier, alarm, and cover rules come from the locally adopted code. Many rural Missouri counties have not adopted a county building code, and a county code applies only outside city limits; inside a city, the city's own code governs. Pool wiring and bonding follow the electrical code adopted locally; in areas without a code, following the current National Electrical Code is still strongly recommended. Missouri has no statewide residential building code; whether a permit is required depends entirely on the city or county code that covers the address.
Local detail for Chesterfield: Chesterfield does not run its own building department. Building permits and inspections for Chesterfield are handled by St. Louis County, which the city contracts with; the city handles zoning approval first.
