Wildfire hazard mitigation

Home hardening and wildfire hazard mitigation

What is home hardening?

Home hardening describes steps that can be taken to make a home more resistant to damage from a wildfire, such as using materials for siding and/or roofing that resist ignition during a wildfire, installing fire resistant windows to protect openings, or using attic ventilation devices that help reduce ember intrusion.

Home hardening, along with creating defensible space, decreases the likelihood that a nearby fire will ignite your structure, and it reduces the potential for damage.

Fire hardening makes the community more resistant to the spread of wildfire. By slowing down a fire, it may create additional time and opportunity for emergency responders to protect life and property threatened by the fire.

What is required?

Where adopted by the local municipality, the construction of new one- and two-family dwellings and certain new accessory structures located within the locally designated wildfire hazard zones are required to comply with the provisions of Oregon Residential Specialty Code (ORSC) Section R327, Wildfire Hazard Mitigation.

Voluntary compliance

Home hardening measures intended to reduce potential damage from wildfires may be voluntarily followed for new construction, and when replacing exterior elements of existing construction. These provisions may be followed throughout Oregon; particularly where your existing home is located in an area subject to wildfires, or where you are looking to build in a wildfire-prone area where the R327 provisions have not been adopted locally.

Wildfire home hardening guide

This guide includes specific recommendations on how to construct new or retrofit existing components of a home to withstand wildfire. Each section of this guide contains an explanation on how the component is vulnerable to wildfire and what can be done to improve that component.

Estimated cost of home hardening

A wide range of variables impact the cost of hardening a home and estimating a cost increase from standard prescriptive construction, including materials selected, size of dwelling, size and number of projections and decks, eave heights, number and type of vents, number and type of windows, and similar customer design considerations.

Wildfire Hazard Mitigation training

This training video covers construction standards and material compliance requirements from for wildfire hazard mitigation or home-hardening. This training is intended to identify the appropriate construction standards required where the wildfire hazard mitigation provisions of the 2023 ORSC are applicable.
