For years, the conversation around wildfire safety in Lamorinda focused on 'Defensible Space,' the 100-foot buffer between your home and the wildland. But as fire behavior evolves, experts are shifting their focus to the most critical area of all: Zone 0.
Zone 0 is the space from 0 to 5 feet around your structure. In many cases, it is the difference between a home that survives and one that is lost.
Why Zone 0 Matters
During a wildfire, homes are rarely lost to a 'wall of flame.' Instead, they are lost to embers. These tiny, wind-blown firebrands land in gutters, under decks, or against the base of your house. If they find fuel within that first five feet, like dry mulch, dead leaves, or a wooden broom, they start a fire directly against your siding.
MOFD 2026 Enforcement
Starting this April, the Moraga-Orinda Fire District (MOFD) is stepping up enforcement of Zone 0 requirements. This is not just a suggestion anymore; its a critical component of community-wide resilience.

Moving Toward 'Hardening'
Hardening your home and clearing Zone 0 are two sides of the same coin. While clearing vegetation prevents fire from reaching the house, 'hardening' ensures that any embers that do reach the structure cant find a way in. Specific hardening requirements vary by jurisdiction and property. Check with your local fire district for guidance tailored to your home.
