Florida Septic systems: what it allows on a lot
Septic systems is Florida law, and the official source is at floridahealth.gov.
New septic systems need a permit from the county health department.
Whether it applies to one lot turns on where the lot is and what it is zoned; the city, county or state office named in the law decides. Mapped areas are approximate. This is a plain reading of public law with its source, not legal advice.
