Repair Permit

A residential/commercial repair permit is required to repair an on-site sewage disposal system.

Getting Started

  • An application to repair an existing on-site sewage disposal system (alteration permit) requires a septic installation permit
  • You must both be the owner and occupant of the house in order to do the work yourself. This work may not be done on a dwelling that is now or will be for sale, lease, rent or exchange in the near future.
  • For other residential or commercial properties, a licensed State of Oregon, Department of Environmental Quality (DEQ) installer has to do the installation
  • If you have any questions, please call the Environmental Soils section at (503) 823-6892
  • There is also a Department of Environmental Quality (DEQ) surcharge to be paid along with the fee

  • Land Feasibility Study Number (for major repair)
  • Scaled legible site plan showing all existing structures, existing and proposed repair septic system, and private well (if applicable)
