Checking a Clermont property's septic history
Three free state lookups that show a Clermont home's septic permit history before you buy
Florida publishes its septic permitting records, and all three of the relevant databases can be filtered to Lake County - which means a Clermont buyer can check a property's septic history for free before the inspection contingency runs out. The Florida Department of Health's OSTDS Final Approvals search is the most useful of the three: it filters by owner, county, street address, ZIP, and application type, and it returns an approval field showing whether the system was Approved or Disapproved, the inspector, the document numbers, and a final system approval date. The application types it distinguishes matter too - OSTDS New, OSTDS Repair, OSTDS Existing, OSTDS Existing Modification, OSTDS Existing Repair, OSTDS Holding Tank, and OSTDS Abandonment - so you can see not just that work happened but what kind.

The other two close the loop. OSTDS Construction Approvals filters by city, county, ZIP, and document number and shows that a system was approved to be built; OSTDS Permits Issued in the Last 30 Days filters by county, application type, agent, owner, address, and ZIP, and is the fastest way to see current Lake County permit activity. Read them together: a construction approval with no matching final approval is a specific, answerable question to put to a seller before closing, because in Florida the final approval is the record that the finished system was actually inspected and signed off. Pair the record check with a physical inspection - the what a septic inspection includes guide and the septic inspection when buying a house guide cover what the field work should cover, and the septic inspection cost guide covers pricing.

The abandonment records deserve their own look in Clermont, because this is a city that converts properties from septic to sewer. When a home connects to central sewer the old tank is supposed to be closed out under a permit, and the state's permit-type lists carry both OSTDS Abandonment and a separate OSTDS Abandonment (General Permit or Utility) category. If a Clermont-area listing says the home is on city sewer, the abandonment record is how you check that the tank was properly abandoned rather than simply left in the ground - a distinction that shows up later as a settlement or collapse problem in the yard, not on the closing statement.

What the records will not tell you is whether the system you are looking at may legally be replaced in kind, and in Lake County that answer is moving. Lake County's own June 2025 land-development staff report states that the county contains three basin management action plan areas - the Upper Ocklawaha River BMAP, the Wekiva BMAP, and the Silver Springs BMAP. FDEP's February 2026 enhanced nutrient-reducing requirements tables show that the trigger is no longer a single acreage test: alongside the long-standing rule that lots one acre or less inside a BMAP require an enhanced nitrogen-reducing system on a new-construction permit (in force since July 1, 2023), the tables add a category under which any size lot inside a priority focus area requires one as of January 5, 2026, so the basin your parcel sits in now matters as much as its size. For existing systems the same FDEP tables record that in springs BMAP remediation areas conventional systems must adopt enhanced nitrogen treatment, install a system achieving at least 65% reduction, or connect to central sewer no later than 20 years after the BMAP's adoption - for the 2018 Wekiwa Spring and Rock Springs BMAP that is a horizon roughly two decades out, not an obligation that has already landed, which is worth knowing if a contractor presents an upgrade as legally required today. Separately, Lake County staff brought a proposed amendment to the county's land development regulations to the Planning and Zoning agenda on June 4, 2025 that would require an enhanced nutrient-reducing system or a distributed wastewater treatment unit wherever regional sewer is not available and would bar conventional systems for new development or to replace an existing system of any kind in unincorporated Lake County; the draft in that packet carries no ordinance number and we have not been able to confirm whether it was adopted, so confirm the current rule with Lake County before you price a conventional replacement outside the city.
