Oregon Licensed DEQ Septic Evaluations

​In Oregon, licensed DEQ septic evaluations are required for rural property transfers and are often requested whenever a system’s performance is in question.

 

A proper septic evaluation not only ensures compliance with state requirements, it also identifies defects that may affect system performance, property value, or future use.

Why a Licensed DEQ Evaluation Matters:

Septic systems are buried and expected to perform quietly. When systems fail or are unknown, they can create:​

​

  • Uncovered defects at closing that delay or derail transactions

  • Costly repairs that surprise buyers and sellers

  • Unknown liabilities for future owners

  • Complications with permitting or remodeling

  • Future property "Master Plan" limitations

​

An Oregon Licensed DEQ evaluation protects the transaction and your investment by identifying issues early and documenting them correctly.
