1,000-square-foot detached Accessory Dwelling Unit (ADU) in Covina, California was thoughtfully designed as a long-term retirement home. The two-bedroom, two-bath residence features an open floor plan that maximizes natural light, comfort, and everyday functionality. Aging-in-place design principles were incorporated throughout to support future accessibility and independent living. A multi-zone mini-split HVAC system provides efficient climate control for each living space, while low-maintenance artificial turf creates a clean, inviting outdoor environment that can be enjoyed year-round. The result is a modern, comfortable home designed for lasting quality and ease of living.
