Savannah is an ISO Class 1 city. ISO stands for the Insurance Service Office. It is a leading source of information about property/casualty insurance risk. ISO expert staff collects information about municipal fire protection efforts in communities throughout the United States. They analyze the relevant data to determine a community’s Public Protection Classification — a number from 1 to 10. Class 1 generally represents superior property fire protection. The ISO classification system evaluates everything from fire department training aids to the distance between fire hydrants. Virtually all U.S. insurers of residential and business property use the ISO Public Protection Classification system to calculate premiums. In general, the price of fire insurance in a community in an ISO Class 1 City is substantially lower than in communities with a poor ISO rating, assuming all other factors are equal.
