Insurance Services Office (ISO) Rating

Insurance Services Office is a division of Verisk Analytics, that reviews and rates fire departments. This rating is used by insurance companies to help determine fire risk and develop rate structures. "ISO" ratings range from 10, being the lowest rating, to 1, being the best. These ratings generally correlate to how much it costs to insure a property, with lower homeowners rates being paid by those with lower number ratings. ISO audits generally occur every five years.
