This project upgrades an existing garage by adding a modern second-story Accessory Dwelling Unit (ADU) that delivers comfort, efficiency, and full LADBS code compliance. The new unit forms a complete independent living space—featuring a full kitchen, living area, bedroom, 3/4 bathroom, and an in-unit washer/dryer—efficiently arranged within approximately 496 sq ft.
Additionally, the project includes a 90.9 sq ft fire-rated under-stair storage area at ground level, built to meet all LADBS safety requirements.
