Oregon building inspector certification
Oregon certifies inspectors at the state level, and an ICC pass does not let you inspect by itself. The agency is the Building Codes Division (BCD) of the Department of Consumer and Business Services. Its rules on who needs what are short, so this guide sticks to what BCD's own pages say, and points you to BCD for anything they leave open.
Who needs certification
BCD says every person who performs building official duties, code inspections or plan reviews must hold an Oregon Inspector Certification (OIC) and an Oregon code certification for the work. They are two separate credentials. BCD's manual says the OIC class covers the basic operation and administration of the Oregon code system, and BCD says it can be obtained only by completing a class through the Oregon Inspector Training Program. BCD's certification manual (last updated December 2024) adds that the OIC takes a training application with a fee, the division's orientation and course, and a passing score on the OIC exam. The manual lists the fee as $125, so check the current amount before you apply.

Three ways to get a code certification
The manual describes three paths:
- BCD's residential courses. BCD runs residential inspector courses for the electrical, plumbing and structural or plans examiner scopes. The manual says no experience is needed for these, and places are subject to space.
- Converting an ICC certificate. BCD's national-certification page says any ICC or other national certification must be converted before you can do that work in Oregon. To convert, you first need an OIC, then you send a conversion application, proof of the current expiration date and the fee.
- A BCD exam. Some certifications have a state exam for people with specialized experience. The manual says exams and courses do not exist for every certification.

Where the B1 fits
The manual's conversion table pairs ICC's B1 Residential Building Inspector with the Oregon Residential Structural Inspector certification, and R3 Residential Plans Examiner with the Oregon Residential Plans Examiner certification. So if you plan to inspect residential structures in Oregon by the ICC route, the B1 is the exam this site prepares you for. The B1 outline guide shows what it tests, and the B1, B2 and R5 comparison helps if your job covers more than residential building.
Keeping the certification
BCD says all inspector certification holders must complete a code change class to stay active. Its renewal page describes the current cycle, where holders had to finish code update training and self-certify by 1 June 2026. The manual says the OIC itself renews on a three-year cycle. The manual says renewals fall due on 1 June in 2023, 2026, 2029 and every third year after, whatever your issue date. Confirm current dates with BCD.
Budget
Keep the state costs and the ICC costs apart. BCD sets its own application, OIC and conversion fees. ICC sets exam fees, which the ICC exam cost and scheduling guide and the exam cost calculator cover. Add code books and study time.
FAQ
Is passing the B1 enough to work as an inspector in Oregon?
No. BCD requires the OIC plus an Oregon code certification, and an ICC certificate can be used for the second only after conversion.
Do I need experience?
BCD says its residential courses need none. Other routes can. Check the pathway for the certification you want.
