The State Building Codes Division (BCD) adopted the 2018 International Residential Code, including Appendix Q, as part of the Oregon Reach Code to provide minimum standards for the construction of tiny houses (400 square feet or less, not including loft areas). These code provisions establish a new occupancy classification for tiny houses on wheels (R-5).

The Bureau of Development Services building official Terry Whitehill will be working with staff to develop implementation information and materials in the near future.
