The layout places the primary bedroom suite on the left with its own walk-in closet and en-suite bathroom, while two additional bedrooms sit on the right sharing a walk-in closet, second bathroom, and washer/dryer area. The open kitchen and living area occupy the lower portion of the plan, creating a comfortable family-sized living space within a compact 26' × 40' footprint.

Why a 3-Bed / 2-Bath ADU?

At 1,000 sq ft, the Sierra reaches California's maximum allowed ADU size, giving you the most livable space possible. The dual-bathroom layout with a primary suite provides comfort and privacy that rivals many full-sized homes, making it an excellent investment for property owners seeking top rental returns.
