Florida requires septic contractors to hold a registration and business authorization under the DEP Operator Certification Program (formerly under DOH). County health departments permit installations, repairs, and inspections — and Florida's periodic pump-out and inspection rules are among the strictest in the Southeast. If you're buying a home with a septic system in Nassau County, ask for the permit history and get an inspection before closing.
