Regional wildfire smoke infiltration.
Even homes that don’t burn take heavy smoke and soot during regional fires. The January 2025 Palisades Fire burned the Pacific Palisades, Malibu, Topanga, and Brentwood corridor — close enough that smoke and ash reached Encino for days, and HVAC systems pulled it into homes. Encino Hills, Royal Oaks, and south of Ventura Blvd all faced the smoke even though the active burn was miles away.
