ISO Information

Public Protection Classification (PPC) is the countrywide classification system used by the Insurance Services Office, also known as ISO Mitigation, to grade a community’s local fire protection. This grade is then used to set property insurance rates. The public fire protection of a city, town, or area is graded using ISO’s Fire Suppression Rating Schedule to develop the community’s classification.

Excellent ISO Rating Means Superior Fire Protection and Reduced Insurance Rates

Lake Travis Fire Rescue is recognized as an ISO Class 2 Department in the Cities of Bee Cave, The Hills, and Lakeway. Most unincorporated Travis County areas are in an ISO Class 3, these areas include River Place, Steiner Ranch, Comanche Trail, Marshall Ford, Mansfield Dam, Hudson Bend, Apache Shores, and Cardinal Hills.

The Insurance Safety Office (ISO) rating Is used by Insurance companies to define the risk factors of your property. It includes items like the distance from the house to the nearest fire hydrant or fire station. The farther away you are, the higher the rate and class rating may be.

ISO collects information on fire-protection efforts in communities throughout the United States. In each of those communities, ISO analyzes the relevant data using our Fire Suppression Rating Schedule (FSRS). It then assigns a Public Protection Classification from 1 to 1 O. Class 1 represents exemplary public protection, and Class 10 indicates that the area’s fire-suppression program doesn’t meet ISO’s minimum criteria. The rating is based on the fire district’s ability to receive, respond to and mitigate fires (60%) while assessing the hydrant and water supply capabilities of your local water provider (40%). It is possible in some developing areas outside of municipalities will have a class rating of 8b, 9, or 10. The higher rating may be a result of either the lack of fire hydrants within 1000′ of a home: the distance from a recognized fire station beyond five road miles, or both.

Some insurance companies choose not to use ISO ratings In favor of using Subzone Rating Factor System. In these cases, homeowners will need to work with their insurance provider to obtain “subzone” ratings. The District can assist with providing information to an insurance company choosing to use subzone ratings in lieu of a specific ISO Class rating.
