Full Breakdown
Lake Forest Municipal Code § 8.25.010, added by Ordinance 385 (February 17, 2026), adopts the CalFIRE Local Responsibility Area Fire Hazard Severity Zone Map dated March 24, 2025. Property mapped in a designated zone must meet Chapter 7A of the California Building Code, which governs materials and construction methods for exterior wildfire exposure, including roofing, vents, siding, and decking. The designation applies at building-permit review for new construction, additions, and qualifying alterations within city limits, not to unincorporated Orange County land.
Violations & Fines
Building without Chapter 7A wildfire-exposure materials in a mapped severity zone is enforced through the city's adopted Building and Fire Code violation provisions, which authorize permit denial and misdemeanor penalties for uncorrected hazards.
