What the ember-resistant zone rules mean for this city, under its actual designation and its actual fire authority.
The local snapshot
The City of Ventura, San Buenaventura on the county seal, is the county seat and this site's namesake city, and it carries the county's heaviest single memory of wildfire loss. Its hillside neighborhoods hold real, current Very High designations under the city's own mapping process, administered by the independent Ventura City Fire Department rather than the county. The first five feet is the highest-leverage prevention within those zones, and the city's 2017 experience is why it reads differently here than almost anywhere in California. Statewide Zone 0 is Proposed — not in force.
The local record
On December 4, 2017 the Thomas Fire ignited and ran at the coast with Santa Ana winds behind it, and before the first night ended more than 500 Ventura residences were destroyed, most in the hillside neighborhoods above downtown. The fire would eventually burn 281,893 acres across two counties, destroy 1,063 structures, and stand for a time as the largest wildfire in California history, but for this city the defining fact is the speed: one night, one wind event, five hundred homes. Embers arriving ahead of the flame front ignited fuel at the house line, which is precisely the five feet Zone 0 governs.
Who enforces it
The City of Ventura runs its own independent Ventura City Fire Department, not VCFD, with its own hazard-mapping process confirmed through the city's public FAQ. Inside city limits, the city's adopted maps and schedule control. The deadlines page names what is Required now versus Proposed — not in force; your jurisdiction sets the specifics, and this page names yours. For the requirements themselves, start with the regulations guide, fences and gates, and landscaping.

Because more than 500 Ventura residences were destroyed in the fire's first night in December 2017, most in hillside neighborhoods. It remains the county's clearest local demonstration of ember-driven loss, the exact mechanism Zone 0 exists to interrupt.
