ISO Fire Ratings

Insurance Program

The Insurance Services Office, Inc. (ISO) is the leading supplier of statistical, actuarial, and underwriting information for and about the property / casualty insurance industry. The ISO fire insurance ratings for a community are the foundation on which most insurers build their coverage programs.

Ratings Basis

The ratings are based on many factors, including:

  • Building Codes
  • Building Inspection Programs
  • City Communication Systems
  • Quality of the Fire Department
  • Water Supply and Hydrant Locations

The ISO ratings range from 1 to 10, with 1 being perfect. Since the ISO fire ratings are used by property insurance companies to set insurance premium rates, the lower the ISO fire rating, the lower the insurance premium.

Current Rating

The City of Edwardsville has been awarded an ISO rating of 4, which is one of the lowest ratings awarded to the communities in Southern Illinois. Our good rating reflects our extensive training, aggressive Building Plan Review, and Building Inspection programs.
