Which Oregon building code governs residential construction of one and two-family dwellings?
Correct Answer
C) Oregon Residential Specialty Code
The Oregon Residential Specialty Code governs construction of one and two-family dwellings and townhouses.
Why This Is the Correct Answer
The Oregon Residential Specialty Code (ORSC) is Oregon's adopted and amended version of the International Residential Code (IRC). It governs the design and construction of one- and two-family dwellings and townhouses not more than three stories in height. The Oregon Building Codes Division administers it.
Why the Other Options Are Wrong
Option A: Oregon Structural Specialty Code
The Oregon Structural Specialty Code (OSSC) governs commercial and multi-family buildings that fall outside the scope of the ORSC. It is based on the International Building Code, not the IRC, and does not apply to typical single-family homes.
Option B: Oregon Mechanical Specialty Code
The Oregon Mechanical Specialty Code regulates HVAC, ventilation, and fuel gas systems — not the overall construction of residential dwellings. It applies to mechanical installations within buildings of all types.
Option D: Oregon Fire Code
The Oregon Fire Code governs fire prevention, protection systems, and occupancy fire-safety requirements. It does not serve as the primary construction code for one- and two-family dwellings.

R = Residential: Oregon **R**esidential Specialty Code covers **R**esidences (1–2 family). If it has a front door for a family, it's the ORSC.
