Wildfire risks are rising, and preparation has never been more critical. The Oregon State Fire Marshal's Defensible Space Program is here to help Oregonians protect their homes and communities through proactive, practical measures.

Scheduling a free defensible space assessment is easy and ensures your property is better protected from the next wildfire season. The assessment is an education-focused visit that gives home and property owners tips to start or improve their defensible space.
