What it is and who needs it.
What the bond actually guarantees
St. Charles County licenses master plumbers and conditions that license on a $10,000 surety bond. The bond is a code-and-public-protection guarantee: it stands behind your compliance with the county plumbing code and the conditions of your license.
It's a three-party arrangement: you, the licensed plumber (the principal), the surety carrier standing behind you, and St. Charles County (the obligee). If a plumber violates the county code or the license terms and the county or a harmed party suffers a loss, they can recover against the bond.
It is not insurance for you — if the surety pays a claim, you repay the surety. The bond is filed in the name of the individual applying for the license, and it must stay active for as long as you hold the license.
