Fire protection plans
CWUIC Chapter 6 requires site‑specific fire protection plans (preliminary and final) that analyze wildfire risk and specify access, water, fuel‑reduction and long‑term maintenance measures.
Last reviewed: July 6, 2026
Overview
This part of the California Wildland‑Urban Interface Code (CWUIC) sets the requirements for project‑specific fire protection plans that evaluate and mitigate wildfire risk for buildings, developments and sites in WUI areas. The code authorizes the code official to require a fire protection plan and specifies who may prepare it (registered design professional, qualified landscape architect, qualified fire‑safety specialist, or other specialist acceptable to the code official) under §602.1 .
The plan must be grounded in a wildfire hazard assessment (location, topography, aspect, climate and fire history) and demonstrate conformance with applicable state wildfire regulations and local ordinances. It must address fire department access, egress, signage, water supply, fuel reduction and defensible‑space measures (including reference to PRC 4290 and PRC 4291 or Gov. Code 51182) as described in §602.2 and §602.3 .
Submittal and approval procedures are defined for preliminary and final plans. Final plans must include project maps, plant species lists for fuel‑modification zones, irrigation/maintenance zones and legally binding maintenance statements (e.g., CCR language) and must be reviewed and approved before construction begins, per §602.3, §602.3.1 and §602.3.2; these requirements sit within Chapter 6 (Fire Protection Requirements) of the CWUIC .

6 FIRE PROTECTION REQUIREMENTS
User notes:
About this chapter: In addition to the building construction requirements in the California Building Code and California Residential Code, this chapter contains requirements for development and construction in Local Responsibility Areas (LRA) designated as Very High Fire Hazard Severity Zones and areas designated by the State Fire Marshal as State Responsibility Areas (SRA). While many of these provisions are found in Title 14 and Title 19 of the California Code of Regulations, they are replicated here for the code user. The local jurisdiction has the authority to apply the same regulations to LRA when the regulations are adopted by local ordinance.
The requirements in this chapter reference the process for adoption of Very High Fire Hazard Severity Zones in the LRA; criteria for evaluating existing subdivisions that are at significant fire risk and are without an adequate secondary egress; and criteria for fire safety provisions required in the Safety Element of a city or county General Plan.
The chapter includes mitigation strategies to reduce the hazards of fire originating within a structure spreading to wildland and fire originating in wildland spreading to structures. These strategies are included in the following requirements:
1. Development of fire protection plans.
2. Development of landscape plans and long-term vegetation management.
3. Creation and maintenance of defensible space to protect structures and subdivisions.

CWUIC § 1-2 High relevance — show source text
Population growth and the expanding urban development into traditionally nonurban areas have increasingly brought humans into contact with wildfires. According to the National Fire Protection Agency (NFPA), every year, wildfires burn across the United States and a growing number of people are living where wildfires are a real risk. In 2018 more than 58,000 fires burned nearly 9 million acres across the US. More than 25,000 structures were destroyed, including 18,137 residences and 229 commercial structures. California accounted for the highest number of structures lost in one state due to the number of significant fires, including the Mendocino Complex, Carr, Camp and Woolsey fires.
The IWUIC is a model code that is intended to be adopted and used supplemental to the adopted building and fire codes of a jurisdiction. The unrestricted use of property in wildland-urban interface areas is a potential threat to life and property from fire and resulting erosion. The IWUIC has as its objective the establishment of minimum special regulations for the safeguarding of life and

property from the intrusion of fire from wildland fire exposures and fire exposures from adjacent structures and to prevent structure fires from spreading to wildland fuels, even in the absence of fire department intervention.
Safeguards to prevent the occurrence of fires and to provide adequate fire protection facilities to control the spread of fire in wildland-urban interface areas are provided in a tiered manner commensurate with the relative level of hazard present.
