The Insurance Services Office (ISO) rating is a classification devised by the insurance industry to rate a community's fire protection. These classifications are used to determine the insurance premium for homeowners and businesses. The rating is based on a scale of 1 to 10 with 1 being the best rating.
In Spotsylvania County, properties located within 5 road miles of a responding fire station have a classification rating of 2. All other properties are rated a class 10 (unclassified).
