OIC Safety Standards & Compliance 3 — Questions and Answers
Question 1: During an Oregon residential inspection, an inspector notices a handrail that does not return to the wall at the bottom of a stairway. Which code section most directly addresses this issue?
- ORS 479.540
- Oregon Residential Specialty Code (ORSC) R311.7.8 (Correct answer)
- OAR 437-002-0380
- ORS 701.325
Correct answer: Oregon Residential Specialty Code (ORSC) R311.7.8
ORSC R311.7.8 requires handrail ends to be returned to the wall, post, or terminate in a newel post to prevent catching clothing or causing injury.
Question 2: An inspector finds that smoke alarms in a newly constructed Oregon home are not interconnected. Under the Oregon Residential Specialty Code, when is interconnection required?

- In all newly constructed dwellings with more than one sleeping area (Correct answer)
- Only when the home exceeds 3,000 square feet
- Only in homes with attached garages
Correct answer: In all newly constructed dwellings with more than one sleeping area
The ORSC requires all smoke alarms in new construction to be interconnected when the dwelling has more than one sleeping area, so activating one alarm activates all.
Question 3: An Oregon inspector is reviewing a residential deck that was built without a permit. Under ORS 701.305, which of the following best describes the inspector's obligation?
- Issue a stop-work order immediately
- Document the violation and refer it to the CCB (Correct answer)
- Approve the work if it appears structurally sound

Correct answer: Document the violation and refer it to the CCB
Under ORS 701.305, an inspector who discovers unpermitted work must document the violation and refer it to the CCB for enforcement action.
