The Insurance Service Office is an independent private company that rates a community's ability to provide fire protection and services. Departments are rated on a scale of 1 to 10, with 1 being the best and 10 being the poorest.
In 2001, the City of Tomball was awarded a Class 1 designation for the area inside the city limits and a Class 2 designation for the areas in Harris County Emergency Services District #15. Since then, we have worked diligently to maintain the best ISO rating available.
These public protection classifications are used by most insurance companies to set rates for their policy holders. The lower the class number the lower the insurance premium, thus there is a significant benefit for a community to invest in its fire protection system. Check with your insurance company and insure that it is crediting you with a class 1 or 2 rate.
