Past fire is history, not a forecast. The chance of fire on a lot today depends on what the record doesn't show: the forest and grass around it, the slope, what has been thinned or burned since, and how far it is from a fire hall.
Before you buy or build, ask the local government or fire department about the fire protection area, FireSmart work and the distance to a fire hall, and ask your insurer what they need.
