Oregon Defensible Space Code

Update as of August 4, 2022

The Oregon Department of Forestry (ODF), the agency responsible for the development of the wildfire risk map, announced they are withdrawing the initial map and notifications. Read the ODF press release here.

The OSFM is continuing to develop the new defensible space code, which will be complete by December 2022, and the effective date will be announced in 2023. This announcement changes the effective date and where the code will apply, but the code will still be developed by December 2022.

For more information, to submit public comment about the defensible space code, or for town hall meeting information, please see below.

Oregon Defensible Space Code

Under Senate Bill 762, the Office of State Fire Marshal is mandated to adopt a statewide minimum defensible space code. The OSFM is using its standing code considerations, development, and adoption process. Agencies, interest groups, and individuals are welcome to provide input during the adoption process. 

The OSFM and stakeholders are following the established code adoption process using the International Wildland-Urban Interface Code model language, using sections 603 and 604 per the Senate Bill 762 mandate. Upon adopting the new Oregon Defensible Space Code, the OSFM will re-evaluate every three (3) years and follow the same systematic policies and practices in place for the Oregon Fire Code.

The code development process will be complete by December 2022 and go into effect in 2023.

Wildfire Risk Map - Withdrawn as of 8/4/22

If your home or business is in the wildland-urban interface and at high or extreme risk, you may be subject to the Oregon Defensible Space Code. Homes and businesses not in the WUI and at high or extreme risk are not subject to the code. 

The OSFM recommends that home and business owners at high or extreme risk but not in the WUI follow defensible space best practices. Wildfire does not recognize map boundary lines.

Find your risk level on the wildfire risk map here. Please note the original map was withdrawn on August 4 and may look different as data layers were removed for further development. The map was developed by Oregon State University and the Oregon Department of Forestry.

Building Codes Division

The Building Codes Division (BCD), is developing rules to:

  • Amend the current Oregon Residential Specialty Code (ORSC) Section R327 to apply to all new dwellings and the accessory structures of dwellings in extreme and high wildfire risk classes in the wildland-urban interface.
  • Amend the current Oregon Residential Specialty Code (ORSC) Section R327 to extend wildfire hazard mitigation building code standards to apply to existing dwellings that are replacing exterior elements of the structure.

These changes will be effective Oct. 1, 2022, and mandatory on April 1, 2023. For more information, click here.
