What materials are commonly used for ADU construction?

ADU construction materials are selected based on structural performance, energy efficiency, durability, and visual compatibility with the existing property. Common materials include wood framing, stucco, roofing systems, insulation, drywall, modern windows, and energy-efficient doors. Interior finishes often include engineered flooring, quartz countertops, tile showers, compact cabinetry, and efficient lighting systems designed for smaller spaces. In West Hills, homeowners frequently choose materials that balance long-term durability with modern Southern California design aesthetics. Exterior finishes are often coordinated with the main residence to maintain a cohesive property appearance. Selecting quality materials helps improve comfort, reduce maintenance needs, and support long-term property value.
