Wildfire Defensible Space: Protect Your Home from Embers

TL;DR: Most homes lost to wildfire ignite from wind-blown embers, not the wall of flame. Defensible space is how you protect against them.

_Last reviewed: July 2026 · 2 min read_

Most homes destroyed by wildfire don't burn from the advancing flame front — they ignite from wind-blown embers that land on or near the house, sometimes a mile ahead of the fire. Creating "defensible space" denies those embers fuel. Four steps matter most, starting closest to the house. Ready.gov/wildfires has detailed zone guidance.

What is the most important wildfire zone?

The first five feet around the house — the "ember-resistant zone." Clear flammable vegetation within five feet: no wood mulch, dead plants, or shrubs against the walls; use gravel or hardscape instead. Embers collect right against the foundation, decks, and walls, so this immediate zone is the highest priority. Move the woodpile and combustibles away too.

Should I trim branches over the roof?

Yes — trim tree branches that overhang the roof and keep them well clear of the chimney. Overhanging limbs drop leaves and needles onto the roof and into gutters (fuel), and carry fire toward the house. Maintain clearance above and around the roof, and remove dead branches and any "ladder fuels" that let fire climb from the ground into the canopy.

How should I arrange landscaping for wildfire?

Space out shrubs and trees rather than clustering them, so fire can't move continuously from plant to plant toward the house. Break up vegetation with gaps, hardscape, and low-flammability plants, and keep grass mowed. Creating separation in the 5–30 foot zone slows or stops a fire's spread across your property.

Why keep gutters clear in wildfire country?

Keep gutters and the roof clear of dry leaves and pine needles — they're perfect tinder for landing embers, right on top of your house. Clean them regularly (especially before fire season), and consider metal gutter guards. A roof and gutters free of dry debris remove the easiest place for an ember to start a fire.

Frequently asked questions

How far should defensible space extend?

Guidance commonly uses zones out to 100 feet: an ember-resistant 0–5 ft zone, a lean 5–30 ft zone, and a reduced-fuel 30–100 ft zone. Prioritize closest to the house first.

What roofing and materials resist wildfire?

Class-A fire-rated roofing, ember-resistant vents, enclosed eaves, and non-combustible siding and decking dramatically improve a home's odds. Hardening the structure complements defensible space.

FAQ

What plants are safest to keep near a house in wildfire areas?

Low-growing, high-moisture succulents, native groundcovers, and deciduous hardwood trees with minimal resinous sap are safer choices than conifers, ornamental grasses, or dense shrubs that hold dry fuel.

How often should I clear defensible space around my home?

Inspect and clear the 0–5 foot zone at least twice a year—before fire season starts and mid-season—and prune overhanging branches and remove dead vegetation in outer zones annually or whenever you notice buildup.

Can I be fined for not maintaining defensible space?

Many wildfire-prone counties and municipalities enforce defensible space ordinances and can issue citations or fines if your property does not meet minimum clearance requirements, especially during high fire danger periods.

Does homeowners insurance require defensible space?

Some insurers in high-risk states now require proof of defensible space maintenance or a wildfire mitigation inspection to renew coverage, and a few will non-renew policies if the property does not meet clearance standards.
