What the ember-resistant zone rules mean for this city, under its actual designation and its actual fire authority.
The local snapshot
San Juan Capistrano adopted its updated 2025 FHSZ maps with confirmed Very High zones, reflecting the foothill and creek-corridor terrain that surrounds the historic core. Zone Zero (Zone 0) requirements apply to parcels in the mapped zones, with OCFA as the city's fire authority.
Fire record
The oldest community in Orange County now carries some of its newest hazard designations. San Juan Capistrano's exposure follows its geography: foothill edges and the creek corridors threading toward the Santa Ana Mountains. No defining fire appears in this project's verified record for the city, and none is claimed; the designation is the 2025 map cycle doing what it was built to do, capturing terrain-driven risk. For the city's older housing stock especially, the fence attachment in the first five feet deserves early attention.
Who enforces it
OCFA is the Authority Having Jurisdiction here. Statewide Zone 0 is Proposed — not in force. Existing defensible-space law still applies. OCFA Guideline C-05 is a new-construction fuel-modification plan-review rule, not a countywide existing-home Zone 0 ordinance. 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.
