Start with records and requirements
Ask the local permitting authority for permits, approved design or as-built drawings, inspection history, and known alterations. Determine whether the transaction triggers a local inspection, pumping, disclosure, or reporting rule. A general home inspection may not include a complete septic evaluation.
Define the inspection scope
Ask which tanks, access points, controls, pumps, alarms, treatment components, distribution components, and soil treatment areas will be evaluated. Confirm whether records research, locating, pumping, flow testing, photographs, and a written report are included. The appropriate scope depends on system design and local practice.
Read the report carefully
Separate observed conditions from inaccessible components and assumptions. Ask who should evaluate unresolved conditions, what permits apply to proposed work, and whether the report has a stated time limit. Retain the report with the property records.
