Full Breakdown
Eastvale Municipal Code § 110.22.020 adds Section 302.1.1 to the adopted California Wildland-Urban Interface Code, stating that the City Council "adopted the recommendations of the State Fire Marshal made pursuant to Government Code section 51178 and designated those areas within the County as moderate, high, and very high fire hazard severity zones as shown on the Local Responsibility Area Fire Hazard Severity Zones Maps." The city adopted these maps by Ordinance No. 25-05. Section 501.1, also amended by § 110.22.020, defines the wildland-urban interface area to include any zone designated under Public Resources Code §§ 4201-4204 and Government Code §§ 51175-51189, plus the areas mapped under Ordinance 25-05.
Falling inside a mapped zone triggers real construction obligations: buildings must comply with both the California Building Code and the Wildland-Urban Interface Code, and any subdivision or building project must submit a fire protection plan to the code official analyzing wildfire risk, prepared by a registered design professional, qualified landscape architect, or qualified fire safety specialist. The code carves out two narrow exceptions: Group U accessory structures under 120 square feet and Group U agricultural buildings, each only if located at least 50 feet from any applicable building. A single-family home on an existing legal parcel is exempt from the fire protection plan requirement, though it still must meet the underlying construction and vegetation-clearance standards. Because Eastvale contracts with the Riverside County Fire Department, that department administers zone designations and reviews protection plans for property within the mapped hazard areas.
Violations & Fines
Violating any Wildland-Urban Interface Code provision that applies inside a designated fire hazard severity zone, including building without an approved fire protection plan, is unlawful under WUI Code § 109.3.7 as adopted by § 110.22.020, punishable under the city's ordinances and applicable fee schedule as well as Health & Safety Code §§ 17995-17995.5 and Government Code § 51185.
