Re-Inspection of an Existing Residential OSSF:
Most mortgage lenders require a re-inspection of an OSSF whenever a property is sold. Environmental Health Services staff perform a surface inspection for this purpose. The Application for Evaluation of an Existing On-Site Sewage Facility form describes the scope and limitations of this inspection.
