Code adoption in 2019
In the last year Building Codes Division has been in the process of adopting the 2019 Oregon Structural Specialty Code (OSSC) based on the 2018 International Building Code (IBC) including ASHRAE 90.1-2016, the base model code for the energy provisions, and the 2019 Oregon Mechanical Specialty Code (OMSC) based on the 2018 International Mechanical Code (IMC) and the 2018 International Fuel Gas Code (IFGC). These codes will be effective Oct. 1, 2019.
Code adoption in 2020
Through the fall of 2019 and into the spring of 2020, the division is working with the Electrical and Elevator Board, the State Plumbing Board, and the Residential and Manufactured Structures Board to adopt the following codes effective Oct. 1, 2020:
2020 Oregon Electrical Specialty Code (OESC) | Based on the 2020 National Electrical Code (NEC)
2020 Oregon Plumbing Specialty Code (OPSC) | Based on the 2021 Uniform Plumbing Code (UPC)
2020 Oregon Residential Specialty Code (ORSC) | Based on the 2018 International Residential Code (IRC)
The division also intends to update the OSSC energy provisions to ASHRAE 90.1-2019 effective Oct. 1, 2020.
These actions, both through the adoption of the OSSC and OMSC in 2019 and the OPSC, OESC and ORSC in 2020, continue Oregon's leadership in timely and efficient adoption of national model codes.
For those codes intended to become effective Oct. 1, 2020, division staff will focus on making only those adjustments necessary for Oregon to align with model codes or to comply with the residential energy requirements directed by Executive Order 17-20. Areas of the model codes that are unworkable in Oregon, conflict with statutes or executive direction, or that significantly change past practice will not be considered by the division.
