Inspections:

  • Homeowners installing their own systems for personally occupied residences will need to submit a written request to install their own system. Owners will be approved in writing and will be given a written inspection schedule. Inspectors will call the owner and discuss inspection requirements. Once approved owners will be able to call in for inspections. If you are concerned about common installation mistakes, see common site evaluation and construction omissions.
  • 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.
