ADU Contractor in West Hills CA — Costs, Permits & Investment (2026)

ADU Contractor in West Hills, CA — Costs, Permits and Investment Guide (2026)

West Hills is one of the San Fernando Valley’s premier ADU neighborhoods — featuring large lot sizes (7,500–12,000+ sq ft), newer housing stock (1970s–1990s), and a stable family community near the 118 Freeway corridor. Unlike many older Valley neighborhoods where garage conversions dominate, West Hills homes often feature attached garages that are part of the main structure, making new detached ADU construction the most common approach. APLA Construction (CA Lic #1136359) builds detached ADUs and garage conversions throughout West Hills.
