The Liberty Township Fire Department recently reevaluated its Insurance Services Office (ISO) rating. As of April 1, 2018, the department's ISO rating is a 2. Some homeowners and commercial insurance companies base their insurance rates on a fire department's ISO rating. Residents are advised to make sure that their policies are up-to-date with the new ISO rating of 2. In the few areas of Liberty Township where fire hydrants are not available, the ISO rating is 9. This is the best rating possible for a non-hydranted area.
