Monroe County sets the septic rules

Septic permits, sale inspections and installer rules are set by the county health department, not by the city. Pump every one to two years is a recommendation, not a rule.

Inspection at sale
No rule found in the county's published code
Permit steps
Site assessment (soil borings), plans if soils are unsuitable (by a licensed engineer, RS or REHS), permit valid 12 months, then inspections after the gravel bed and piping, of tanks, pumps, alarms and filter, and a final after sand cover and berms.
