Fire record

Old town, new maps

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 immediate-effect fence rule deserves early attention.

Who enforces it

Orange County Fire Authority (OCFA)

OCFA is the Authority Having Jurisdiction here. The state Zone 0 framework is the floor; OCFA's adopted schedule and inspection program 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.
