What the ember-resistant zone rules mean for this community of the City of Anaheim, under its actual designation and its actual fire authority.
The local snapshot
Anaheim Hills has lived with a Very High designation for years, and the 2025 remap grew it: roughly 300 acres were added to Anaheim's existing Very High zone. Anaheim's own fire marshal put it plainly during the remap: the city's acreage would increase by about 300 acres taking the maps as CAL FIRE drew them. In the hills east of the 55, Zone Zero is an expansion of a known reality, not a new one.
Fire record
The November 2008 Freeway Complex Fire, 30,305 acres and 314 residences destroyed, burned through the Anaheim Hills and Yorba Linda corridor together. The canyon-facing streets along Santa Ana Canyon Road saw the same wind-driven ember exposure that defines this whole front of the county. The 2025 expansion of Anaheim's Very High zone follows that history rather than inventing new risk.
Who enforces it
Anaheim runs its own municipal fire department, Anaheim Fire & Rescue, not OCFA. Anaheim Fire & Rescue is the AHJ. Statewide Zone 0 is Proposed — not in force. Existing defensible-space law still applies. Anaheim Fire & Rescue is independent of OCFA. Deadlines pages carry local status labels, not a 2027 to 2028 statewide clock; your jurisdiction sets the specifics, and this page names yours. For the requirements themselves, start with the regulations guide, fences and gates, and landscaping.
