Shed Roof ADU in San Diego
This thoughtfully designed shed roof ADU in San Diego was created to offer a comfortable and private living space for aging parents. At 499 square feet, the 1 bedroom, 1 bathroom layout makes smart use of its narrow footprint while maintaining a warm and functional interior.
The elongated structure measuring 38 feet long and just over 13 feet wide is topped with a modern shed roof that complements the clean lines of the unit. This sleek design is ideal for properties where space is limited but style and comfort are still top priorities.
Smart Layout for Narrow Lots
This ADU layout is a great option for narrow or irregularly shaped lots. It maximizes usability without sacrificing livability. Its efficient design includes a spacious bedroom, open-concept living area, a bathroom easily accessible from the bedroom and living room, and in unit laundry. Because this ADU is under 500 square feet, homeowners may qualify for certain local cost saving exemptions, such as waiving the need for a soils report or reduced wastewater fees.

Why Choose a Shed Roof ADU?
Shed roofs, also known as single-slope roofs, are a popular choice for modern ADU designs. A shed roof ADU slopes in one direction, often toward the rear of the structure. It creates a clean, minimalist profile while allowing for added ceiling height and natural light.
Compared to other roof types like gable, hip, or flat roofs, shed roofs offer a simple and cost effective way to achieve a contemporary look. They’re especially useful for drainage on narrow ADUs and can allow for the installation of clerestory windows to bring in extra daylight.
