What is the Public Protection Classification (PPC) system?

Return to TopReturn to Index

It is the countrywide classification system used by the Insurance Services Office (ISO) to reflect a community's local fire protection for property insurance rating purposes. 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.


Where is the PPC system used?

Return to TopReturn to Index

The PPC system in some form is used in all 50 states. Texas was the last to adopt it. Commissioner Elton Bomer replaced the old key rating system with ISO's Fire Suppression Rating Schedule and related Public Protection Classification system, effective February 1, 1998.


What is ISO?

Return to TopReturn to Index

ISO is a New York-based advisory organization that serves the property and casualty insurance industry by providing inspection services, insurance coverage form development and statistical services. ISO has Texas offices in Dallas and Austin.


How does the PPC system grade local fire protection?

Return to TopReturn to Index

ISO classifies communities from 1 (the best) to 10 (the worst) based on how well they score on the ISO Fire Suppression Rating Schedule, which grades such features as water distribution, fire department equipment and manpower and fire alarm facilities. ISO field representatives use the schedule when surveying a community's fire protection capability. The score that is determined from applying the Fire Suppression Rating Schedule is translated into a public protection classification. A perfect score in Texas is 106.5. It consists of 50 points for fire department capabilities, 40 points for water supply and distribution, 10 points for receiving and handling fire alarms and 6.5 points for a "Texas Addendum" that grades fire safety education, building code enforcement, fire prevention code enforcement and fire investigation capabilities.

How does a community's score translate into a PPC rating?

Return to TopReturn to Index

The following table shows the number of points required for each PPC Class:

Points Required for Each PPC Class
Class Points
1 90 +
2 80 to 89.99
3 70 to 79.99
4 60 to 69.99
5 50 to 59.99
6 40 to 49.99
7 30 to 39.99
8 20 to 29.99
9 10 to 19.99
10 0 to 9.99

What does a dual PPC like 7/9 mean?

Return to TopReturn to Index

The first number is the PPC for buildings within 1,000 feet of a fire hydrant and five road miles of a recognized fire station. The second number is for buildings more than 1,000 feet from a fire hydrant but within five road miles of a recognized fire station.


Does ISO automatically penalize communities for having volunteer fire departments?

Return to TopReturn to Index

No. Canyon's all-volunteer fire department, for example, has a rating of 3.


What does the PPC system mean to me?

Return to TopReturn to Index

Every city, town or area that provides fire protection services is subject to being graded to establish a PPC. Individual buildings - including your house - are subject to the community's PPC. When calculating property insurance premiums, insurance companies using the PPC apply a factor that reflects a particular community's PPC.


Do PPC ratings vary from company to company?

Return to TopReturn to Index

Yes, it can, because some insurance companies do not use ISO.


In general, how do Texas communities stack up?

Return to TopReturn to Index

Larger cities, which tend to have the best fire protection, generally are rated 3 or 4. A few are rated 2. Small towns tend to cluster in the 4-to-7 range. A number of previously un-inspected areas that returned ISO questionnaires about their fire fighting capabilities are rated 7 or 9.


Does my community's Public Protection Classification significantly affect my homeowners' insurance premium?

Return to TopReturn to Index

Although homeowners' insurance rates are driven mainly by your area's claim experience, your community's PPC rating also is important. The premium on a brick veneer house is 39 percent higher in an area rated 10 (worst) than in one rated 1 (best). (This range is even greater for frame houses.) A brick veneer home's rate difference from one class to the next ranges from 1.5 percent to 9 percent.

Brick Percentage Change from Current PPC to Other PPC.
Brick Veneer Percentage Change from Current PPC to Other PPC.
Wood Frame Percentage Change from Current PPC to Other PPC.


Can you give examples of how differences in PPC ratings affect individual homeowners' rates?

Return to TopReturn to Index

Insurer's writing homeowners insurance policies in Texas are not required to use the PPC factors from the Texas Personal Lines Manual. Insurers may file and use their own factors.


What about homes in remote locations?

Return to TopReturn to Index

Any building more than five road miles from a fire station or outside the boundary of a fire protection area, such as a city or volunteer fire department service area is rated 10. An exception is an area that has an "automatic aid agreement" with a recognized and rated fire department to respond to fires in that area. In such cases, ISO assigns the area a rating after evaluating the agreement. Use of the assigned rating will depend on the distance of individual buildings from fire stations.


How can I learn my community's PPC rating?

Return to TopReturn to Index

  1. Ask your SFMO/TDI contact, the PPC Oversight Representative, at 512-305-7941 or e-mail jesse.williams@tdi.texas.gov.
  2. Ask your city manager.
  3. Ask your insurance agent.
  4. Call ISO Customer Service at 1-800-444-4554, menu option 2.

How can my community get a better PPC rating?

Return to TopReturn to Index

By asking ISO for a re-evaluation based on improvements since last inspection. If your community has never been inspected, it needs to start by returning ISO's questionnaire if it has not already done so. City officials can make inquiries by calling ISO Customer Service, 1-800-444-4554 or TDI's PPC Oversight Representative at 512-305-7941. For a re-evaluation, ISO requires a letter from the fire chief or city official.


If my town makes improvements and seeks a re-evaluation, how soon will the improvements affect my homeowners' insurance rate?

Return to TopReturn to Index

ISO publishes evaluations quarterly. For several reasons, including the fact that homeowners policies are written for a year at a time, it may take a year or longer for a re-evaluation to affect an individual homeowner's premium.


Does TDI oversee ISO to assure that PPC ratings are accurate and fair?

Return to TopReturn to Index

Yes, TDI has a PPC Oversight Representative that reviews each proposed new classification rating. This review ensures the accuracy of the survey, and will take no longer than 30 days. This includes 10 days for local officials to comment. If the new rating appears reasonable, TDI authorizes ISO to publish it for use by insurance companies.


Are ISO inspection reports and lists of PPC ratings open records?

Return to TopReturn to Index

Yes, inspection reports may be viewed at ISO's office in Austin (8911 N. Capital of Texas, Westech 360, Bldg. II Suite 2110, telephone 512-440-9900). The current ratings list and certain other documents such as grading sheets and inspections summary sheets are on file with TDI as open records. The Public Protection Classification Office also has copies which are available upon request.
