Summary
Santa Ana is a fully urbanized city with no areas designated as Very High Fire Hazard Severity Zones (VHFHSZ) by CAL FIRE. The city is served by the Orange County Fire Authority (OCFA) and is not subject to wildland-urban interface fire regulations.
The State Fire Marshal is mandated to classify lands within State Responsibility Areas into Fire Hazard Severity Zones (FHSZ). Fire Hazard Severity Zones fall into one of the following classifications: Moderate, High, Very High. The California laws that require Fire Hazard Severity Zones include California Public Resources Code 4201-4204, California Code of Regulations Title 14, Section 1280 and California Government Code 51175-89. [...] The FHSZ maps are developed using a science-based and field-tested model that assigns a hazard score based on the factors that influence fire likelihood and fire behavior.
Full Breakdown
As a densely developed urban city in the coastal plain of Orange County, Santa Ana does not contain any areas classified as Very High Fire Hazard Severity Zones by the California Department of Forestry and Fire Protection (CAL FIRE). The city is entirely within a Local Responsibility Area served by the Orange County Fire Authority. Properties are not subject to the enhanced vegetation management, building material, and defensible space requirements of California Government Code Section 51182 that apply in VHFHSZ areas. Standard California Fire Code provisions for urban properties still apply, including general property maintenance and fire access requirements.
Violations & Fines
While VHFHSZ regulations do not apply, standard fire code violations related to property maintenance, blocked fire access, and combustible material storage are still enforceable by OCFA.
