California now requires ember-resistant materials within five feet of the house in the state's highest fire hazard zones, and that line runs through many East Bay hillside properties. This guide breaks down what the rule covers, which materials qualify, and which local contractors can install them correctly.

What Is Zone Zero in California?

Zone Zero is the part of California's new wildfire rules that applies directly to fencing: a five-foot buffer around the house where nothing combustible is allowed to stand. The requirement comes from AB 3074 and SB 504, and it's being enforced first in the highest fire hazard severity zones, many of which sit in the East Bay hills. Read the full explainer to see exactly what the zone covers, when it takes effect for your city, and how it changes what can sit on your property line.
