ISO Public Protection Classification
Verisk’s ISO Public Protection Classification grades a community from 1 to 10 for structure-fire suppression. Class 1 is superior property fire protection. Class 10 means the area’s fire-suppression program does not meet ISO’s minimum criteria. Most home insurers use PPC in pricing. ISO does not give the class to policyholders. PPC is not a wildfire score and not Oregon R327.
You are on the phone with an agent who said the premium is the fire district’s fault. They mean this grade. It is not your gravel. It is not a nearby burn scar.
No g3-passed exhibit matches this object. Do not reuse SIT-100 as a PPC worksheet.
Why it matters
A Class 10 community can make admitted homeowners coverage scarce even when the house is hardened. A Class 3 community does not make Zone 0 optional. The grade and the house are different books. See premiums with no nearby fire.
How it works
ISO surveys fire-protection areas. The Fire Suppression Rating Schedule turns communications, department, water, and prevention into a class. Insurers buy that class. You do not. The water piece is hydrant inspection, flow testing, and water available versus water needed for structure fire. That is why a rural tank on your lot does not automatically rewrite the community class. Rural firefighting water is still OFC 507.1 for the permit.
How the documents split
| Object | What ISO/Verisk say | What it is not |
|---|---|---|
| PPC 1–10 | Community structure-fire suppression grade | A house score |
| Class 1 | Superior property fire protection | A wildfire-prepared designation |
| Class 10 | Does not meet ISO minimum criteria | “No fire district” as a legal status |
| Who can see it | Insurers, agents, fire officials | Policyholders, this website |
| FSRS scope | Features that reduce structure-fire property loss | EMS, wildland, your Zone 0 |
| Premium | Better PPC, lower fire insurance, other factors equal | A published percent off |
The paths
1. Ask the agent for the class they are using. ISO will not send it to you. Verisk says so.
2. Do not treat PPC as wildfire. The scope page is structure fire. Embers at the vent are home ignitability, not FSRS.
3. Water in PPC is the community system. Hydrant testing and available flow. A tank the fire district accepted for your permit is OFC. It may or may not move the community class. ISO tells fire officials to call when the system changes.
4. Firewise and IBHS are other checklists. Firewise and premiums. They do not replace PPC.
5. Oregon FAIR Plan is residual market, not a class. Oregon FAIR Plan. A poor PPC can be why someone is shopping residual. It is not the FAIR statute.
6. Access is still the fire code. Fire apparatus access does not change because ISO scored the town.
What people mix up
- A public PPC lookup that ISO does not offer.
- A percent discount invented from “substantially lower.”
- PPC as a wildfire hazard map.
- Home hardening as a community class change.
- Class 10 as “the fire department will not come.”
- This grade as R327.
How to check
- Ask the agent which PPC they have on the location.
- If you are a fire official, call ISO at the number on the consumer FAQ.
- Open isomitigation.com/ppc. Read Class 1 and Class 10 in ISO’s words.
- Open the scope page. Confirm it is structure fire.
- Do not paste a blog “PPC-to-premium table” onto a drawing.
- For the permit, stay on OFC 507 and the district guide.
Limits
This page does not report Bend’s or Deschutes’ class. ISO does not publish those classes here. FireApproved is not Verisk and not a carrier. No invented formula.

Questions
Can I look up my PPC online?
ISO’s consumer FAQ says ISO supplies Public Protection Classifications to insurance companies and agents through ISOnet, not to policyholders or the general public. Ask your carrier or agent. Fire officials can call ISO at 1-800-444-4554, selection 2, for the class ISO has for their community.
Does a better PPC lower my premium by a fixed percent?
Verisk says that, assuming other factors are equal, the price of fire insurance in a community with a good PPC is substantially lower than in a community with a poor PPC. That sentence is not a formula. This page does not invent one.
Is PPC a wildfire grade?
No. ISO’s scope page says the Fire Suppression Rating Schedule recognizes fire-protection features only as they relate to suppression of fires in structures. Hydrants, staffing, and dispatch are in. Your Zone 0 gravel is not the PPC worksheet.
If my house is hardened, does my class change?
PPC is a community grade. Home hardening and IBHS designation are different objects. See premiums with no nearby fire, and Firewise and premiums.
