Central Oregon Wildfire Protection
Fire Mitigation Guide for Central Oregon Homeowners
Defensible space, home hardening, and documentation strategies that protect your home \u2014 and can save you 10\u201330% on your wildfire insurance premium.
Why Mitigation Matters
Mitigation Is the Most Powerful Tool You Have Against the Wildfire Insurance Crisis
Central Oregon's wildfire insurance market is in crisis. Carriers are non-renewing policies, raising premiums, and exiting markets across Crook, Deschutes, and Jefferson counties. But homeowners who take documented mitigation action are in a fundamentally different position.
Documented defensible space and home hardening improvements can lower your risk score, qualify you for carrier credits, and \u2014 in many cases \u2014 make the difference between finding affordable coverage and being forced onto the Oregon FAIR Plan.
This guide covers the three defensible space zones required by Oregon law, the home hardening improvements that carriers reward most, and the documentation process that turns your work into insurance savings.

Oregon ORS 477.015
The Three Defensible Space Zones
Oregon law requires a minimum 30-foot defensible space. Most insurance carriers want to see 100 feet documented.
The immediate zone around your home — the most critical area for ember ignition prevention.
- \u2713Remove all combustible materials (firewood, propane tanks, furniture) from within 5 ft of the structure
- \u2713Use non-combustible mulch (gravel, decomposed granite) instead of wood bark or rubber mulch
- \u2713Clear all dead plant material, leaves, and pine needles from against the foundation
- \u2713Ensure no plants or shrubs are touching the structure
- \u2713Clean gutters and roof valleys of all debris
- \u2713Screen all vents with 1/16” – 1/8” corrosion-resistant metal mesh
The lean, clean, and green zone — irrigated, low-fuel landscaping that slows fire approach.
- \u2713Maintain well-irrigated, low-growing plants and lawn (grass under 4” height)
- \u2713Space plants in islands — no continuous vegetation from ground to tree canopy
- \u2713Remove all dead plants, dry leaves, and fallen branches regularly
- \u2713Prune tree branches to a minimum 10 ft height from ground
- \u2713Space trees so canopies do not touch (minimum 10 ft between canopies on flat ground)
- \u2713Remove all ladder fuels (shrubs under trees that allow fire to climb)
The reduced fuel zone — thin and space vegetation to slow fire spread and reduce intensity.
- \u2713Thin ponderosa pine and juniper to reduce canopy density (Oregon ORS 477.015 requires 30-ft clearance)
- \u2713Remove all dead trees, snags, and down logs within this zone
- \u2713Space conifers so canopies do not touch (minimum 18 ft on slopes over 20%)
- \u2713Remove shrubs and brush from under tree canopies
- \u2713Mow grass and annual weeds to under 4” height during fire season
- \u2713Create fuel breaks along driveways and property lines

Home Hardening
Structural Improvements That Carriers Reward
Defensible space reduces fire intensity approaching your home. Home hardening prevents ignition once embers arrive. Both are rewarded by carriers.

How It Works
Three Steps to Lower Your Wildfire Insurance Premium
Complete Your Mitigation Work
Start with Zone 0 (most critical), then work outward. Focus on the highest-impact improvements first: ember-resistant vents, roof cleaning, and removing combustibles from within 5 feet of your home. Oregon ORS 477.015 requires 30-foot defensible space — but most carriers want to see 100 feet documented.
Document Everything
Documentation is what turns your mitigation work into insurance savings. Take dated photos of every improvement — before and after. Keep receipts. If you pursue Wildfire Prepared Oregon certification (a third-party inspection program), that documentation carries significant weight with carriers.

Oregon Building Code
Oregon R327 \u2014 What It Means for Your Insurance
Oregon R327 is a residential building code that applies to new construction and major renovations in WUI zones. It requires fire-resistant roofing, siding, vents, and other structural features designed to reduce ember ignition.
If your home was built or significantly renovated to R327 standards, this is valuable documentation. Carriers that actively write in Central Oregon's WUI zones often offer underwriting credits for R327-compliant construction.
See our Home Hardening Insurance Guide for more detail on how specific improvements are evaluated.
Class A Roofing
Metal, tile, or Class A asphalt shingles — the single most impactful R327 requirement for insurance purposes.
Ember-Resistant Vents
1/16”–1/8” corrosion-resistant metal mesh on all vents prevents ember intrusion — the #1 cause of home ignition in wildfires.
Non-Combustible Siding
Stucco, fiber cement, brick, or other non-combustible exterior materials reduce ignition risk from radiant heat.
Multi-Pane Windows
Tempered or fire-rated glass windows resist radiant heat and reduce the risk of glass failure during a wildfire event.
