Pleasanton, CA Fire Regulations: Wildfire Zones (2026)

Fire Hazard Severity Zone (FHSZ) maps classify land as Moderate, High, or Very High wildfire-hazard based on terrain, vegetation, fire history, weather, and ember exposure. The Livermore-Pleasanton Fire Department notes that recent California legislation expanded mapping to include Moderate and High zones in Local Responsibility Areas (city lands) in addition to Very High zones. Pleasanton's City Council adopted the 2025 California Wildland-Urban Interface (WUI) Code by ordinance, codified at PMC Chapter 20.22, which the city pairs with its adopted California Fire and Building Codes. The practical consequences for property owners in mapped zones are significant: new construction and renovations in High and Very High zones must comply with WUI ignition-resistant building standards (such as Chapter 7A materials), homeowners in Very High zones must maintain defensible space around structures, and sellers are required to disclose a property's FHSZ designation during a real estate transaction. Properties in the WUI are also subject to LPFD's more restrictive vegetation-management standards, including tree and shrub spacing. The Fire Hazard Severity Zone reflects the natural hazard, not the post-mitigation risk; owners reduce their actual risk through defensible space (vegetation management) and home hardening (fire-resistant construction). Residents can look up a parcel's FHSZ designation using LPFD's online map tool by address or assessor's parcel number.
