Zone 0 data
Zone 0 by ZIP code: how much of your neighborhood is covered
California's Zone 0 rules cover the first 5 feet around a home, but only in certain fire hazard areas. We mapped those areas against every home in Los Angeles, Ventura and Santa Barbara counties. Find your ZIP below.
Updated November 11, 2026. The Board of Forestry re-adopted the Zone 0 rules on November 5, 2026. They are not in effect yet. They start only after the Office of Administrative Law approves them and they are filed with the Secretary of State.

What stands out
It's not only the canyons
- City neighborhoods, not just canyons
- Highland Park (90042) has more covered homes than any ZIP in the three counties: 17,407, or 78%. Eagle Rock is at 76%, and the Hollywood Hills (90068) at 100%.
- Whole communities are in
- Practically every home in Pacific Palisades (100%), Topanga (99%) and La Cañada Flintridge (100%) is in a covered area.
- Foothill towns are split
- In Altadena, 36% of the land but only 22% of homes are covered, because the 2025 local map marks the foothills Very High and most of the flats lower. Sierra Madre is similar: 49% of land, 28% of homes.
If you're in a covered area, the rules ask for a clear 5 feet: no wood mulch, no firewood, nothing burnable against the walls or under decks, and no new trees, phased in over up to five years. Read the full Zone 0 guide for the list and timeline, or see what each fire hazard zone means.
How we counted
Method and limits
Covered area. The adopted rules apply on all State Responsibility Area land and in Very High Fire Hazard Severity Zones on local land. We used CAL FIRE's official 2024 state map and its 2025 local map, the same maps behind our address check.
Homes. 2020 Census housing units by block. When a block is partly in a covered area, we counted homes in proportion to the share of the block's area that's covered.
ZIP codes. The Census Bureau's ZIP Code Tabulation Areas, which match mail ZIP codes closely but not exactly. Land share uses Census land area, so ocean doesn't count.
- Home counts are from 2020. They include homes lost in the January 2025 fires and miss homes built since.
- A city or county can map more land Very High than CAL FIRE did. Those local additions aren't in this count.
- Federal land, like national forest, isn't covered by the state rules and isn't counted.
- These are estimates for planning and research. Your own parcel is in or out; check it with the address tool above.
Questions
Zone 0 by ZIP, answered
- Is my ZIP code in Zone 0?
- Zone 0 isn't drawn by ZIP code. It's the 5 feet around each building, and the state rules reach a home if it sits on State Responsibility Area land or in a Very High Fire Hazard Severity Zone on local land. Most ZIP codes are split, so this table shows the share of homes and land that fall in those areas. To know for sure, check your exact address with the tool on this page.
- Is Zone 0 in effect?
- The Board of Forestry re-adopted the Zone 0 rules on November 5, 2026. They are not in effect yet. They start only after the Office of Administrative Law approves them and they are filed with the Secretary of State.
- Why does my ZIP show a percentage instead of a yes or no?
- Fire hazard zones follow hills, canyons and open land, not ZIP lines. In most ZIP codes the streets nearest the hills are in and the flats are out. The percentage tells you how common it is in your area. Your own parcel is either in or out.
- Why is Altadena only 22%?
- Most of Altadena is local responsibility land, where the state rules cover only Very High zones. CAL FIRE's 2025 local map marks the foothills Very High but not most of the flats, including much of the area that burned in the Eaton Fire. The counts also use 2020 Census homes, before the fire. Rebuilt homes in covered areas will have to follow the rules.
- Why are city neighborhoods like Highland Park so high?
- CAL FIRE's 2025 local map marks large parts of northeast and central Los Angeles Very High, including Highland Park, Mount Washington, Eagle Rock, El Sereno and the hills around Silver Lake and Echo Park. In those areas the state Zone 0 rules would apply just as they do in the canyons.
- Where do these numbers come from?
- CAL FIRE's official Fire Hazard Severity Zone maps (the 2024 state map and the 2025 local map) and the 2020 Census count of homes by block. We counted the homes in each block in proportion to how much of the block falls in a covered area. The method and its limits are below.
