Mountain communities including Idyllwild, Mountain Center, and communities along Highway 74 face significant Zone Zero obligations. Desert communities in the Coachella Valley generally have lower FHSZ exposure. Phase 2 timelines will be set by the local AHJ for each jurisdiction.

High-FHSZ communities in Riverside County include Idyllwild, Mountain Center, Anza, Hemet foothills, Lake Elsinore hillsides, Murrieta foothills, Temecula wine country, Beaumont-Cherry Valley, and communities along Highway 74 and the Santa Ana River corridor.
Local FAQs
Does Zone Zero apply to homes in Idyllwild and other mountain communities? Yes — mountain communities in the San Jacinto Mountains are in Very High FHSZ and Zone Zero requirements will apply fully.
