450 SF Garage Conversion ADU in San Francisco
Located in a dense San Francisco neighborhood, this project converts a compact 450-square-foot garage into a fully functional accessory dwelling unit. The design maximizes every inch of space to deliver a comfortable living environment while navigating complex city zoning and strict building codes.
Tight urban constraints & challenging city requirements
Converting a garage in San Francisco presents unique challenges: limited square footage, strict fire-separation requirements between units, and the need to maintain independent utility access. The homeowners wanted a rental-ready unit that felt spacious despite its small footprint, requiring creative storage solutions and precise layout planning.
Cramped garage interior with low ceilings.
Limited access for construction materials.
Typical SF garage requiring facade modernization.
Smart spatial planning for maximum efficiency
To make 450 SF feel larger, we utilized an open floor plan that combines living, dining, and kitchen areas into a cohesive "great room."
Vertical space was maximized with floor-to-ceiling cabinetry and high shelving. A large sliding glass door replaces the old garage door, flooding the unit with natural light and opening onto a private patio.
We engineered the fire separation walls and ceiling to fully comply with S.F. Building Code, ensuring safety and privacy for both the main house and the ADU tenant.
Open layout maximizing usable square footage.

From storage space to premium city living
The transformed space is a stylish, self-contained apartment. High-quality finishes, strategic lighting, and efficient appliances turn a dark garage into a desirable rental property in one of the city’s most competitive markets.
Maximizing value in a high-cost market
