An area’s ISO ratings reflect fire preparedness, not the risk of fires in a given area. Therefore, the prevalence of wildfires does not directly affect a community’s ISO rating. For example, a community in Southern California could have a near-perfect ISO rating depending on its water supply and fire department capabilities, despite being located in an area where wildfires are prevalent. However, if that same community has problems with water supply, it could negatively impact their ISO score, since it would likely affect the ability to suppress both structural fires and wildfires.
