What the ember-resistant zone rules mean for this city, under its actual designation and its actual fire authority.
The local snapshot
Ojai sits in its oak-ringed valley almost entirely surrounded by wildland, and the 2025 remap treated it accordingly: the city's Very High acreage more than tripled, as reported by The Acorn. The Thomas Fire burned the valley's rim in 2017 and the town remembers watching the ridgelines glow. Zone Zero (Zone 0) applies within the mapped zones, and in a town this canopied, the honest conversation is as much about what the rules don't require (removing healthy oaks) as what they do.
The local record
In December 2017 the Thomas Fire encircled the Ojai Valley, burning the surrounding ridges while the town itself was spared the worst structure loss that Ventura's hillsides suffered. The experience of being ringed by fire, evacuation routes limited to a few valley exits, is why Ojai's preparation culture runs deep and why the 2025 remap's tripling of the city's Very High acreage surprised few residents. The practical takeaway for Zone 0 is specific to this town: the first five feet at the structure is the controllable piece, and the oak canopy conversation belongs with VCFD, not with a chainsaw crew acting on a headline.
Who enforces it
The Ventura County Fire Department (VCFD) is the Authority Having Jurisdiction here. The state Zone 0 framework is the floor; VCFD's adopted schedule and programs set the local specifics. Deadlines pages carry the state defaults; your jurisdiction sets the specifics, and this page names yours. For the requirements themselves, start with the regulations guide, fences and gates, and landscaping.
Questions
The city's Very High acreage more than tripled in the 2025 remap, as reported by The Acorn. For a town ringed by wildland on nearly every side, the updated modeling formalized what the geography always said.
No. The April 2026 draft scaled back blanket vegetation restrictions after statewide concern about mature trees, and local rules may allow well-maintained trees. Verify with VCFD before removing anything; the clear requirement is a noncombustible first five feet at the structure.
It burned the valley's surrounding ridges in December 2017 and put the town through encirclement and evacuation, though Ojai was spared the concentrated structure loss Ventura's hillsides suffered. The memory shapes the valley's preparation culture to this day.
