Oregon Septic Contractor License Requirements (2026)
By Gabriel Giner, Editor · Source checked 2026-09-30
Oregon requires a Sewage Disposal Service business license for septic installation and for advertising that service. The installer or combined installer/pumper business must identify at least one appropriately certified person to supervise the work. Individual certification alone does not license the business. The business application, bond, and each project’s onsite permit are separate parts of lawful operation.
