## The ember-resistant zone (first 5 feet)

Embers, not walls of flame, ignite most homes. The first 5 feet around your house should be the most defensible:

- Use noncombustible materials (gravel, pavers, concrete) against the foundation
- Remove bark mulch, dead plants, and stored combustibles in this zone
- Keep this area clear under decks and stairs

## Defensible space (out to 100 feet)

- Zone 1 (5 to 30 feet): trim trees, remove dead vegetation, space shrubs
- Zone 2 (30 to 100 feet): reduce and space fuels, keep grass mowed
- Move woodpiles and propane tanks away from the home

## Home hardening (the structure)

- Class-A fire-rated roof - the single most important upgrade
- Ember-resistant (1/8-inch mesh) vents to keep embers out
- Enclosed eaves and noncombustible siding near the ground
- Dual-pane or tempered windows that resist heat
- Noncombustible gutters kept clear of debris

## Community programs

Neighborhood efforts count too. Firewise USA recognition and California's Fire Risk Reduction Community designation can help at the community level, and some markets weigh them in underwriting.

## Frequently asked questions

### Does home hardening lower insurance costs in California?

It can. Under the Safer from Wildfires regulation, insurers must recognize specific mitigation such as a fire-rated roof, ember-resistant vents, and defensible space in eligibility and pricing.

### What is the most important wildfire upgrade?

A Class-A fire-rated roof and a clear 5-foot ember-resistant zone around the home are among the highest-impact steps, since embers igniting the roof or nearby fuels cause many home losses.

### How far should defensible space extend?

California guidance calls for managing vegetation out to 100 feet from the home where feasible, divided into an inner and outer zone, plus a noncombustible 5-foot zone right against the structure.
