Quick answer: Placentia carries a Very High designation, with Placentia Fire and Life Safety Department as the local fire authority. Zone Zero requires an ember-resistant zone in the first 0 to 5 feet around structures in the mapped Very High areas, with the combustible-fence restriction taking effect immediately upon adoption of the final regulations.

The local snapshot

Where Placentia stands

Placentia was newly classified in the 2025 remap with all three tiers including Very High, and it brings a distinctive wrinkle: the city runs its own fire department, having left OCFA in 2020 as the first city ever to do so. Zone Zero (Zone 0) compliance here runs through Placentia Fire and Life Safety, not the county authority.

Fire record

New designation, independent department

No wildfire defines Placentia in this project's verified record, and none is claimed. The city's Very High classification arrived with the 2025 remap's updated modeling. What makes Placentia's compliance path distinct is institutional: as the county's newest independent fire department, Placentia Fire and Life Safety is the authority that will adopt local schedules and run inspections here, so Placentia homeowners should watch their own city's announcements rather than OCFA's.

Who enforces it

The state Zone 0 framework is the floor; Placentia's own department sets 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.
