Residential Plumbing Inspector (CAP) course

Course description

The Residential Plumbing Inspector course explains the codes and processes for performing residential plumbing inspections covered by the Oregon Low-Rise Residential Dwelling Code. The course addresses the various components of plumbing installations that are verified during the inspection process. The course is taught through interactive training between the instructor and students, specific questions and assigned research, and progress exams. Students who successfully complete the course and pass the state plumbing inspector certification exam will be issued an Oregon Residential Plumbing Inspector (CAP) certification.

Course requirement: Individuals who have registered and been approved to take the plumbing course who do not hold a current Oregon Inspector Certification (OIC) will be required to enroll for the next available OIC class. Training staff will contact you with available dates.

Please note: Those interested should register immediately once registration is open so your application can be reviewed for consideration. Although we are aware many are waiting to take this course, seating will be limited. Those who work for, or on behalf of, an Oregon building department (county, city or state) will be considered for seating first as we have a responsibility to meet the needs of current inspection services in the state. All other registration requests will be considered in the order received.
