Public Protection Classification (PPC)

Frequently Asked Questions


How does ISO evaluate local fire protection?

And what does the classification mean for individual property insurance costs in my community?

ISO's expert staff collects information about municipal fire protection efforts in communities throughout the United States. In each of those communities, ISO analyzes the relevant data and assigns a Public Protection Classification (PPC®) — a number from 1 to 10. Class 1 generally represents superior property fire protection, and Class 10 indicates that the area's fire suppression program does not meet ISO's minimum criteria.

Virtually all U.S. insurers of homes and business property use ISO's Public Protection Classifications in calculating premiums. In general, the price of fire insurance in a community with a good PPC is substantially lower than in a community with a poor PPC, assuming all other factors are equal.

How can our community improve its Public Protection Classification?

If your community makes improvements in its fire department, water supply, or emergency communications system, your community may be eligible for a better PPC. Our ISO Mitigation Online website contains a wealth of information on the subject to assist community leaders.
