Simi Valley requires property owners to maintain defensible space and clear brush within prescribed distances from structures. The Ventura County Fire Protection District enforces vegetation management standards critical to the city's wildfire-prone landscape.
Properties in Simi Valley must maintain 100 feet of defensible space around all structures per California PRC 4291 and VCFPD standards. Zone 1 (0-30 feet from structures) requires removal of all dead vegetation, trimming trees to maintain 10 feet of vertical clearance from rooflines, and keeping grass under 4 inches. Zone 2 (30-100 feet) requires thinning of vegetation to reduce fuel loads by at least 50%. Properties in Very High Fire Hazard Severity Zones (VHFHSZ), which cover significant portions of Simi Valley's hillside areas, face additional requirements. Annual inspections begin in spring with compliance deadlines typically in June.
Non-compliant properties receive a notice to comply with a deadline, typically 30 days. Failure to clear vegetation after notice results in the city or fire district performing the work and billing the property owner, plus administrative fees. Repeat non-compliance may trigger liens on the property. Fines range from $100 to $1,000 per violation.
