Two lots in Oregon can have different wildfire building rules. It depends on the city or county.
Oregon repealed its statewide wildfire hazard map in 2025.
Now the wildfire building standards, called Section R327, apply only where a city or county has adopted them. That city or county also decides where, by a map or a written description. It may not be the whole area.
It covers new construction, like a new house or a new detached accessory dwelling unit. Where it applies, the fire hardening can add $20,000 or more to the house.
The state Building Codes Division lists Ashland, Bend, Deschutes County, Grants Pass and Sisters among the adopters.
Before you buy, ask the local building department: is this lot inside the area where R327 applies? Or order a SiteFacts Report. It covers wildfire, including whether a parcel sits in a wildfire area or a local R327 area, what that triggers, and fire marshal review. The link is in the first comment.
Save this for when you start asking about lots.
