Course information:
This Residential Structural Inspector course is split into two modules:

  • Module 1: During this module, students will learn the codes and processes for performing residential structural and mechanical inspections covered by the Oregon Residential Specialty Code, and the various components of structural and mechanical installations that are verified during the inspection process. Students who successfully complete module 1 will receive a Residential Structural Inspector (CAS) certification. This certification will not be issued until module 2 is successfully completed. 20 weeks.
  • Module 2: During this module, students will learn the process and responsibilities of reviewing residential plans. This process includes how to read plans, note corrections, write a plan review, and read approved plans provided on the jobsite during the inspection process. Students who successfully complete module 2 will receive a Residential Plans Examiner Inspector (CAX) certification. 10 weeks.
​The course is taught through interactive training between the instructor and students, specific questions and assigned homework/research, a progress review, and final review. Students who successfully complete the course will be issued two separate certifications at the end of the 30 weeks; one to perform residential and mechanical inspections and one to approve plan reviews.
