California’s Safer from Wildfires framework is the clearest statewide map of mitigation actions insurers must recognize when wildfire risk affects rating. CDI’s consumer page lists ten homeowner-facing steps spanning structure, immediate surroundings, and community programs; the underlying rating regulation (10 CCR §2644.9, as summarized in CDI FAQs and research notes) requires separate credits for mandatory community and property mitigation factors—commonly discussed as roughly a dozen factor lines when community designations, roof, eaves, vents, glazing, Zone 0, fencing materials, under-deck clearing, outbuilding distance, defensible space, and base-of-wall clearance are counted individually. This Wildfire Compare Pilot article explains the buckets without inventing discount percentages.
Community, defensible space, and hardening buckets
Community: Firewise USA participation and Board of Forestry Fire Risk Reduction Community designation appear in CDI materials as recognized community measures.
Immediate surroundings: 5-foot ember-resistant zone, fencing adjacent to the home, vegetation/debris under decks, combustible outbuildings moved (CDI cites ≥30 ft where controllable), and broader defensible-space compliance with state/local / CAL FIRE rules.
Structure: Class A roof (wood shake is not Class A), ember-/fire-resistant vents (CDI cites 1/16–1/8 in noncombustible metal mesh), noncombustible six inches at the bottom of exterior walls, enclosed eaves/soffits, and upgraded multi-pane windows or shutters.
How carriers must reflect measures in rating
When wildfire risk affects rates, CDI FAQs explain that rating plans must reflect each mandatory community and property mitigation factor with a separate discount or credit. Optional factors may be included if substantially related to wildfire loss. Expect at least a nominal premium reduction per mandatory factor when modeled credits would otherwise round below a dollar—details live in CDI insurer/consumer FAQs. Carriers still file their own rating plans; your renewal math depends on the filing, not a blog table.
Why discounts vary by filing
Two neighbors with identical roofs can see different dollars if their carriers filed different relativities, if one discount applies only to the wildfire peril portion, or if verification status differs. Always request a line-item explanation tied to your score or rating factors.
Building a home plan across categories
Sequence high-ROI, inspection-visible work first: Zone 0 mineral belt, vent upgrades, gutter/debris, fence break, then roof/eave projects on their natural replacement cycle. Add community participation if your neighborhood qualifies. Consider active exterior systems as a supporting layer after the mandatory checklist items are underway.
Evidence that maps cleanly to each category
Label photos and invoices with the CDI step name (“Class A roof — composition shingle — June 2026”). Include product approvals where relevant. For community measures, keep Firewise or FRRC documentation. For defensible space, keep CAL FIRE or local inspection records when available.
Category mapping exercise
- Print CDI’s Safer from Wildfires list and check what you already meet.
- Photograph gaps (mulch in Zone 0, open vents, wood fence attachment).
- Price the next three fixes and schedule them before renewal.
- Ask your agent which filed credits your policy actually uses.
- Re-submit evidence after completion and calendar the follow-up.
FAQ
Is it exactly twelve categories?
CDI’s consumer page highlights ten steps; rating regulation factor lists are often discussed as about a dozen mandatory community/property lines when split out. Use CDI primary pages and your carrier’s filing explanation—not a fixed blog count—as authority.
Do I need every measure?
More completed measures can mean more recognized credits, but start with ignition-critical Zone 0, vents, and roof class.
Where is the official list?

Are active sprinklers on the CDI ten-step list?
The public ten steps focus on hardening, Zone 0, defensible space, and community programs. Sprinklers may still support underwriting conversations as extra documentation—ask your carrier.
How Wildfire Compare Pilot readers should use this guide
Print or save this article beside your quote sheets or insurance binder. Check off each H2 against written answers from installers or brokers. Cross-link to our defensible space, home hardening, insurance, and comparison pages so active defense stays nested inside a layered plan. Re-read before fire season and after any major roof, landscaping, or policy change. If a vendor’s story cannot survive these sections without hand-waving, keep shopping.
Finally, separate marketing from operations. A system that looks complete in a render but lacks a water budget, mute rules, or maintenance calendar is incomplete. An insurance packet that cannot map photos to Safer from Wildfires or state disclosure categories is incomplete. Wildfire Compare Pilot exists to make those gaps visible before you spend.
Next step: Use this Wildfire Compare Pilot guide’s comparison hub to line up options, then request a property inspection from FireShield (disclosed sponsored #1). Verify current specs, pricing, and documentation with every company yourself—and keep evacuation as the non-negotiable plan.
