Start with the Existing Record
Look for the approved capacity, bedroom count, field layout and later repair permits. Compare the record with the current house and yard. An added bedroom, enclosed room, pool or new driveway can affect system demand, access or the available replacement area.
Accessible Tank Components
Review accessible lids, risers, inlet and outlet parts, filter and visible shell condition. Record waste levels and any need for pumping to see components. A visual inspection through an opening does not prove every buried wall or pipe is sound.
Assess the Drain Field Separately
Wet patches, odors and unusually green strips can be clues, but they are not a diagnosis by themselves. Consider recent rainfall, household water use and field layout. Pumped systems also need checks of accessible alarms, controls and dosing components.
Real-Estate Inspection Scope
Specify whether the quote includes locating the tank, exposing lids, pumping, camera work or lateral-line review. A comprehensive inspection and a routine visit are different scopes. Put material findings and recommended follow-up in writing so the buyer can make a useful decision.
County Approval Is a Different Review
A private inspection does not authorize installation or a permitted repair. DOH-Orange handles local septic permitting. Orlando's building checklist also calls for approved health-department septic documentation when additional living space is constructed on a septic-served property.
