2020 Oregon Residential Specialty Code adoption

New model code

The division is working with the Residential and Manufactured Structures Board to adopt the 2018 International Residential Code (IRC) as the base model code for the 2020 Oregon Residential Specialty Code (ORSC).

The anticipated effective date is Oct. 1, 2020.

Energy provisions

As part of Oregon’s 2020 residential code adoption, the division will be adopting the Oregon Zero Energy Ready Residential Code (OZERRC). The OZERRC is a zero ready residential standard and is anticipated to be effective Oct. 1, 2020. Using U.S. Department of Energy guidance, Oregon will achieve strong energy savings for one- and two-family dwellings through an expedited, contractor supported review process. This action continues Oregon’s leadership in energy efficient building codes well into the next decade. The division anticipates providing the Residential and Manufactured Structures Board with a preliminary draft of the 2020 OZERRC standards at the April 1, 2020 board meeting. The board will then take public feedback on the agency proposal.
